]]>Plant-eating insects are an important positive component of healthy ecosystems, but a negative pest in agricultural fields. Consequently, it is important for scientists to quantify the extent of herbivory on plants. Software currently exists to calculate the areas of existing leaves, but not to perform the more difficult task of reconstructing the missing portions of partially eaten leaves.

The co-authors are developing software to reconstruct the missing portions of leaves in photographs by matching the partially eaten leaves with an entire uneaten reference leaf of that same species. They are using three approaches.

One method uses the Hough Transform to isolate the petiole and uses the angle and location of the petiole to determine the rotation and translation necessary to match the partially eaten leaf with the reference leaf.

The second method determines the matching transformation using Random Sample Consensus (RANSAC), which is used to iteratively estimate parameters in a model while ignoring a possibly large set of outliers.

The third method constructs
a multilayer neural network model, which is an artificial intelligence
approach that adjusts the weights in the model during a training phase
based on past experience.

Using data from all postsecondary institutions in the United States sourced from the Department of Education's database, Bright and Hanely used multiple regressions to model a student's education success and then developed an optimization algorithm to approximate optimal allocations of funds for each of their undergraduate success indicators.

Samuel Grieggs, a double major in Mathematics and Computer Science from Indiana, won the award for Best Computational Poster for "A RANSAC Based Approach to Leaf Matching." Grieggs used Random sample consensus (RANSAC) for the purposes of image registration. This was then used to develop a method of estimating what the "true" edges of a leaf are by registering the image of a leaf with a sample leaf of the same type. This gives a general idea of how much of the leaf has been eaten along the edges.

Aeroelastic Flutter is a highly non-linear phenomenon caused by a combination of aerodynamics, inertial forces, and the elastic properties of the wing of an aircraft. Researchers at NASA are working to advance fundamental knowledge of aeroelastic phenomena through the development and application of prediction methods to aerospace vehicles.

In support of their work, we are investigating a data-driven approach to understanding flutter by applying temporal pattern mining algorithms to the experimental data collected during wind tunnel testing. When testing an aircraft model in a wind tunnel, scientists and engineers currently rely on expert observation, monitoring of instrumentation, and the use of Fourier Transforms to convert data from the time domain to the frequency domain. This approach may not always be effective in identifying subtle dynamics that are precursors to flutter.

In his talk, Yagle will discuss the use of pattern mining algorithms to identify repetitive subsequences—or “signatures”—in time series data collected from accelerometers. The family of algorithms being investigated has the capability to mine unprocessed, time-domain data in a fraction of the time required by other methods. Once identified, these signatures can then be mapped to events that occurred during wind tunnel testing.

Detection and identification of significant signatures could lead to new insights about precursors to flutter and other aeroleastic phenomena. An overview of the algorithms and test methodology will be presented, along with a discussion of the potential challenges and benefits to this important area of aerospace research.

In the paper the authors propose a new class of distribution called the beta-exponentiated power Lindley (BEPL) distribution. The article can be found at the publisher's website.

Flowers presented an overview of the Calkin-Wilf tree,
including how it may be used to enumerate the rational numbers. He also
summarized how the tree relates to the classical combinatorial question of
counting integer partitions. In particular, Calkin and Wilf proved that
the tree counts hyperbinary partitions.

Flowers then reported on recent work with
Shannon Lockard of Bridgewater State University, where they introduce an
*m* - ary tree that is a generalization of Calkin and Wilf’s tree. Flowers gave
characteristics of this tree and showed how these trees can reveal and
verify new properties of the hyper *m* - ary partition function.

Bouchat discussed graphs and their associated ideals, showing how results in the structure of the graph can lead to results in the minimal free resolution of the path ideal. She also talked about the process of developing mathematical conjectures in "colorful" ways.

The paper “A new Class of Generalized Dagum Distribution
with Applications to Income and Lifetime Data” was also co-authored with Broderick Oluyede of Georgia Southern University and Shujiao Huang, a graduate student at Georgia Southern, and concerns the Dagum distribution. The Dagum distribution is a sub-model of the generalized beta distribution of the second kind and plays an important role in size
distribution of personal income. The article is published in *Journal of Statistical and Econometric Methods*,
3(2), 125-151, 2014.

The other two papers were co-authored with Gayan Warahena-Liyanage, a student in the Applied Mathematics graduate program at IUP. The first, “A New Class of Generalized Inverse Weibull Distribution with Applications,” concerns mathematical properties of the distribution, which is

useful for failure time data analysis. Professor Oluyede also shared co-author credit on this paper, which appeared in *Journal of Applied Mathematics & Bioinformatics*, 4(2), 17-35, 2014.

The second paper, “A Generalized Power Lindley Distribution with Applications,” appeared in *Asian Journal of Mathematics and Applications*, 1-23, 2014. The authors introduce the Exponentiated Power Lindley distribution, which is an extension of the Power Lindley Distribution. This new distribution represents a more flexible model for lifetime data.

From 11:15–12:05, Vanden Bosch will speak on “Variations on a Theme by Sierpinski,” extending the Sierpinski gasket to the topic of random walks. This talk will be held in Weyandt Hall, room 107.

Finally, Vanden Bosch will speak on “The Goldilocks Fallacy,” concerning decision making and the Law of Large Numbers. This talk will be from 3:35–4:35 in Stright Hall, room 226.

Abstracts for Vanden Bosch’s talks can be found on the S-COAM page.

Peter Vanden Bosch currently teaches mathematics at Marymount University. He served in the USAF for 26 years,
culminating as chief of analysis and science and technology advisor
for USNORTHCOM and NORAD. He also worked in a think tank on homeland security
issues for three years. Vanden Bosch also taught high school for seven years. He has published
articles on mathematics education, nuclear effects, stochastic
processes, military doctrine, homeland security, numerical estimation,
and the psychology of decision making. Vanden Bosch earned a PhD in Operations Research at the Air Force Institute of Technology.

The first workshop, “Introduction to Python,” will be held on Thursday, October 9, from 3:30 to 5:00 p.m. in Stright Hall, room 220. In this workshop, Chrispell will introduce
participants to Python scripting using a Linux environment
with the goal of modeling an N-Body problem. Topics covered will include
package management for the Linux OS, importing Python libraries, and basic
scripting for numerical computation touching on classes, functions, and
plotting data.

The second workshop, “Python II: Image Processing with Python,” will be held on Thursday, October 16, from 3:30 to 5:00 p.m. in Stright Hall, room 220. In this second workshop, Donley will teach some fundamental procedures for analyzing images and will implement those procedures in the Python programming language using popular Python packages. Image processing tasks will include edge detection, line detection, and identification of objects within images. This second workshop is intended for people who already know a programming language.

If you are interested in attending one or both workshops, please RSVP using the following Qualtrics link: RSVP Link

These workshops are cosponsored by the Mathematics Department, the S-COAM program, and the IUP Software Development Center.

Johnson is an associate of the Casualty Actuary Society and a member of the American Academy of Actuaries. He also serves as treaty underwriting manager and senior vice president with Swiss Re America Holding Corporation.

Johnson will discus the various traditional and nontraditional roles for a property and casualty actuary in the insurance and reinsurance market. He'll talk about how these jobs differ with respect to passing actuarial exams, hours of work, job quality, and salaries.

Johnson will also discuss the recommended course work and skills needed to be successful in an actuarial career.

In 1999, Neil Calkin and Herb Wilf “recounted”
the rationals on a binary tree in their article “Recounting the Rationals” in Volume 107, Number 4 of the *American Mathematical Monthly*. Their new approach to an ancient problem
has been featured in many places, including the book *Proofs from THE BOOK*, containing what some consider to be the most elegant proofs of famous mathematical theorems. It also led to several other results and generalizations from numerous
authors. However, the Calkin-Wilf tree is also related to the classical
combinatorial question of counting integer partitions. In particular,
they proved that the tree counts hyperbinary partitions.

Flowers will recap the results above, including a fun way to
enumerate the rational numbers. Then, he will introduce an *m*-ary tree that is
a generalization of Calkin and Wilf’s tree. Finally, he will discuss
characteristics of this tree and show how he used these trees to reveal and
verify new properties of the hyper *m*-ary partition function.

Flowers’ talk is intended to be accessible to undergraduate students.

Colen along with co-presenters Jung Colen (MEd '11, currently at Penn State University) and Jinho Kim (Daegu National University of Education) presented an ethnographical approach to reporting two elementary school teachers' math talk move facilitation. The vignettes of the classroom discussions between the students and teachers depicted how they used the math talk move to interconnect mathematical concepts.

"Math Talk Moves" afford a community of learners frequent opportunities to articulate their
mathematical thinking and to assess their peers’ conjectures and conclusions.
The presented moves are not unguided, aimless discourses. Rather, the moves
serve as an instructional tool to probe for student understanding and to
scaffold their mathematical learning.

In the first part of the talk, we will recall the basic
theory of impartial games. We’ll learn how to win at familiar games like NIM
and precision bowling. Then, we’ll apply this knowledge to study games in which
two players alternately pick elements of a given group until the picked
elements generate the group.

NASA systems are becoming overly
complex, with newer challenges surfacing every day. Gone are the days where we can afford to rely on “Heroes” to come and save the project. The good news is that NASA does not have to rely on “Heroes”; there exist proven, scientifically generated engineering methods and tools to help deploy successful systems.
But to do so requires an opening of minds to accept that there may be two cultures that need to be bridged.

Even though NASA may be focused on building, testing, and delivering a particular subsystem, it must embrace the holistic perspective which is driving our particular
subsystem entirely. It is difficult for the human to create the solution—how do you teach intuitive synthesis needed to go from perception of problem to an idea for
its solution? Over the years, Systems Engineering has promoted that it brings tools and methods to the table to help bridge this gap. In
this talk, Fisher will explore the concept of two cultures and its effects on system development, and in particular how the Independent Verification and Validation approaches strive to
integrate the holistic view when determining whether or not a software system will work.

Marcus Fisher’s presentation is sponsored by the S-COAM program spearheaded by Yu-Ju Kuo and Rick Adkins.

The Mathematical Contest in Modeling is an annual international
competition, with 6755 teams participating this year from 18 countries. Teams of up to three undergraduate students
spend an intense four-day weekend at their home institution, working on an open-ended
realistic mathematical problem.

The team of Mathematics and Economics double major Ashleigh
Craig (Hollidaysburg, Pa.), Geology and Computer Science double major Daniel O’Hara
(Ebensberg, Pa.), and Mathematics major Theresa Scarnati (Erie, Pa.) worked on a
model to analyze the performance of the “Keep Right Except to Pass Rule” in
light and heavy traffic. The team
analyzed throughput versus safety, the role of speed limits, and other factors
in analyzing this model. The team of
Craig, O’Hara, and Scarnati were declared “Meritorious Winners,” placing their
work in the top 10 percent of all entrants.

Ashleigh noted that “It was pretty intense. You only have four days to do all the
research, create and test the model, and write up a report.” Theresa added that “the Mathematics
Department faculty members were great. They kept us fueled with food and snacks throughout the weekend. The students also made use of the computing
facilities of the Mathematics Department.

The team of Craig, O’Hara, and Scarnati used a combination of partial
differential equations, discrete simulation in MATLAB, and a technique known as “time
stepping” in their analysis. Ashleigh
and Theresa noted that they learned about time stepping in John Chrispell’s
Numerical Methods class.

The team of Mathematics and Physics double major Ross
Newcome (Reading, Pa.), Mathematics major Sean Smith (Annandale, Va.), and
Computer Science major Michael Taylor (Waynesboro, Pa.) also worked on the
traffic model, earning a “Successful” designation for their modeling of the
problem. Newcome, Smith, and Taylor wrote a rules-based discrete simulation model and a risk analysis discrete simulation model in Java.

A team of exchange students from China majoring in Finance, Yifei
Hu, Zhen Yang, and Huidong Zhang, worked to create a mathematical model to
analyze and declare the “best all-time college coach,” male or female, for the
past century. The team of Hu, Yang, and
Zhang used three operations research models of increasing
complexity to refine their choice of best coach of the century—the simplex
method, a combination of Data Envelopment Analysis and Grey Relational
Analysis, and then they added economic and life expectancy indices. Hu, Yang, and
Zhang earned an
“Honorable Mention” for their model, placing their work in the top 42 percent of all
entrants.

It was Hu, Yang, and Zhang
who initiated IUP’s participation in the competition. Ed Donley of the Mathematics Department,
who served as one of the advisers for the students, said, “Yifei knew of the
COMAP modeling competition because it is very popular in China. He stopped by my office and asked if I would
sponsor their team in the competition. I
was familiar with the COMAP modeling contest, but IUP has never
participated. I was enthusiastic about
giving students an authentic applied mathematics experience—working as a team
on a complex mathematical problem that does not have one ‘correct’
solution. I enlisted Dr. John Chrispell
to work with me to assemble and orient the teams.”

Chrispell added, “I teach the
operations research course sequence, so I know most of our students’
mathematics and programming capabilities. We recruited our best students with a breadth of mathematics, science,
and computer science backgrounds for the competition.”

Donley and Chrispell hope to make this an annual event
in the Mathematics Department. Ed
commented, “I have already had some sophomores come up and ask me if we can
participate next year. So, the pump is
primed.”

COMAP (Consortium for Mathematics and Its Applications), is
an award-winning, nonprofit organization whose mission is to improve
mathematics education for students of all ages. In each year since 1984, COMAP has sponsored the Mathematical Contest in
Modeling for undergraduate students.

Plant-eating insects are important members of ecosystems
because they convert the photosynthetic energy of plants into high protein and
fat resources for birds and other insect predators. A healthy terrestrial ecosystem requires
abundant insect fauna. Many non-native
plants are less preferred food sources for insects, but no studies have been
done to determine the exact quantitative level of preference for native plants
over non-native ones.

To determine this, an accurate method is needed to
measure the amount of native plant foliage consumed by insects. Current leaf area calculation software
systems only find the areas of existing leaves. They cannot perform the more difficult task of reconstructing missing
portions eaten by insects.

This
interdisciplinary collaboration will produce a software system to reconstruct
images of the missing portions of leaves that have been partially eaten by
insects. In an accompanying field
experiment, the software will be used to accurately measure insect feeding
preferences for several significant native verses non-native plants in
ecosystems.

Student participants in this research project are from
Computer Science, Biology, and Mathematics. The leaf area calculation software will be distributed freely to other
researchers.

Web analyst is a position that is emerging in our
data-driven society. The goal of this presentation is to bring awareness
to the web analyst field, provide a day in the life of a web analyst, and show
some useful tools that are used by web analysts. With virtually everything
online being trackable, the benefits are endless for companies employing
people who love data. Companies are investing thousands, even millions of
dollars with insights they are gaining from web analysts. With the world
becoming more and more digitally focused, the opportunities are only going to
increase for people with strong analytic skills. There is a huge lack of
awareness for this field, especially among math majors.

After this presentation
is complete, you will have a better understanding of whether or not being a web
analyst is for you.

R is a free statistical software package that is extensively used in both academia and
industry. It is an open source platform with more than 5,000 contributed packages that include the latest statistical analysis tools.

In this two-day
workshop, Stocker will introduce the major
components of R. This will include importing and exporting data, descriptive statistics, graphics,
inferential statistics, statistical
modeling, and simulation studies. Participants in the workshop will use the R package to analyze a
variety of data sets and will receive
example R code and output.

If you wish to attend, please RSVP via e-mail to Yu-Ju Kuo of the Mathematics Department: yjkuo@iup.edu.

Failure
detection and fault correction are vital to ensure high-quality software.
During the development and deployment phases, detected failures are commonly
classified by severity and tracked to meet quality and reliability
requirements. Besides tracking failures, this data can be analyzed and used to
qualify the software and to control the development and maintenance process.
Our work is focused on failure data collected during the development phase and
explores what we can learn by analyzing this data. Change management systems
log the failures detected and the code fixes to correct the underlying software
defects. By applying software reliability models and statistical techniques to
this defect data, we can answer questions such as the following:**
**

- Is the maintenance process increasing the software reliability?
- Is the maintenance process under control?
- How many failures are expected to occur in the field?
- What is the expected time remaining to meet the reliability requirement?

**
**This
presentation addresses these questions by using a methodology based on trend
analysis, control charts, and software reliability growth models. The
methodology is applied to a large software system during various stages of
testing including customer acceptance testing.
What is new about this methodology is the combined use of control
charts, trend analysis, and software reliability models.

The
saturation of mobile phone markets has resulted in rising costs for operators
to obtain new customers. These operators thus focus their energies on
identifying users that will churn so they can be targeted for retention
campaigns. Typical churn prediction algorithms identify churners based on
service usage metrics, network performance indicators, and demographic information.
Social and peer-influence to churn, however, is usually not considered. In this
talk, a new churn prediction algorithm is described that incorporates the influence
churners spread to their social peers. Using data from a major service provider,
it is shown that social influence improves churn prediction and is among the
most important factors.

]]>Rosenberg will give three presentations. Verification of attendance can be provided for students.

2:00–3:00 p.m., Stright 327/329

We have a collection of prices that reflect brand preferences from a retail client. Think of a grocery store chain with various name brands like Kellogg’s, General Mills, or Quaker Oats and private-label store brands. Think Cheerios versus “Tasty-O’s.” We are trying to quantify the price relationships among N brands based on existing prices.

We’re going to use a least-squares fit to find N-1 brand values (if we fix one of them) based on the N*(N-1)/2 observed price ratios. We avoid the trivial solution of all the values equal to zero by imposing a single constraint on the magnitude of the values.

Starting with the derivation of the basic formula for minimizing the least sum of squared error with linear coefficients, we’ll add the single constraint and derive the formula we’re using in our own brand-value calculation.

3:30–4:20 p.m., Stright 327/329

A discussion of three decades of Operations Research work.

5:00–6:00 p.m., Stright 327/329

For each of N products p we have a selection of M(p) prices. Each of these prices has revenue R(P) and profit pi(P) [that’s supposed to be the Greek letter pi for profit] associated with that price. The revenue and profit value are derived from retail demand models. We want to know the best price for each product.

The concept of “best” depends on our relative weight of revenue and profit. We consider a pure-revenue objective to be lambda=zero and pure profit to be lambda=one with a continuum of revenue-profit lambda optimization weights in between. The goal of this work is to present all the optimal price possibilities for all N products over the zero-to-one range of lambda.

We’ll start by finding the optimal price for each product as a function of lambda. That involves finding the frontier, part of the convex hull of the revenue-profit values for all the prices.

Rather than enumerate M-to-the-N price-choice possibilities, we’ll find their convex hull in revenue-profit space with nothing more computationally vigorous than sorting the individual-product solutions once. While this two-objective frontier is complete and exact, extension this method to three objectives (for example, revenue, profit, and units sold) is diluted to a good approximation.

Adam Rosenberg has three decades of mathematical decision-support expertise in industries including retail science, airline optimization, financial-market analysis, hotel yield management, railroad line simulation, and telephony. He started his career at Bell Telephone Laboratories developing the emerging cellular telephone systems. He also worked in printed circuit board design and manufacture and wrote a book on CDMA, the most-recent mobile telephone technology. Many of his software solutions have remained in production for over a decade and they have earned or saved hundreds of millions of dollars for his employers and clients. Rosenberg earned his M.S. and Ph.D. degrees from Stanford University in Operations Research and his A.B. from Princeton University in Mathematics (cum laude). He holds several patents.

]]>Labant, a graduate of the Secondary Mathematics Education program from Indiana, Pa., received an award for best Mathematics Education Work Sample at the Women in Mathematics, Science, and Technology Program held on April 1. Labant’s faculty supervisor was Edel Reilly. Labant is currently a mathematics teacher at Robert E. Lee High School in Springfield, Va.

Craig, from Hollidaysburg, and Scarnati, from Erie, both junior Applied Mathematics majors, presented their research on Model for End-Stage Liver Disease (MELD) scores and survival rates of liver transplant recipients. Their research, which started as a class project in Rick Adkins’ Modeling and Simulation class, models the effects of the MELD scores on the survival rates of liver transplant recipients. The purpose of their model is to determine how to allocate livers so that they will be used most effectively. It is best to provide a liver to a patient with a higher rate of survival after transplantation over someone with a small chance of survival. MELD scores range from 0 to 40, with the national average of 20. Craig and Scarnatti examined data from Ohio, Pennsylvania, and West Virginia to determine which values are optimal for saving the most lives with liver transplants.

]]>Homology groups are an important algebraic invariant of topological spaces, while infinite loopspaces are an important type of topological space.

McCarty and his coauthor address the question of how one can compute the homology groups of infinite loopspaces from information about their "stable" homology groups, by integrating many topological and algebraic ideas.

A full abstract can be found at the journal's website.

]]>Ryan’s thesis work has involved the mathematical modeling of both Newtonian and viscoelastic fluid flow inside a journal bearing. To model the flow inside a journal bearing, numerical simulations using an Oldroyd-B/Navier-Stokes fluid solver and the immersed boundary method were conducted. Model parameter studies showed the effects of viscolasticity and viscosity on the flow generated between two rotating annular geometries.

]]>The MAA is an organization for those interested in mathematics and mathematics education. The Allegheny Mountain Section serves all of western Pennsylvania and most of West Virginia. The annual spring meeting provides numerous mathematical and social activities for faculty and students.

The Mathematics Department is very excited to host this event. Several IUP faculty and students will be presenting at the meeting. Also, many faculty and students are volunteering their time to ensure that things run smoothly.

]]>Pi Day is celebrated every year on March 14 (3-14). The Preservice Teachers of Mathematics (PTM) auction off chances to “pie a professor,” with all proceeds going towards awards and prizes for children during Family Math Night, a PTM program for children and parents to show the fun side of mathematics.

]]>The article proposes inferences procedures for assessing the generalized Koziol-Green model that is used to analyze recurrent event data where informative right censoring is present. The procedures are constructed using functionals of a class of empirical processes. Asymptotic properties of the resulting procedures are established and finite sampling properties are investigated via a computer simulation study. The procedures are applied to a data set that contains the recurrence times of bladder tumors for patients in a study.

]]>Details on all the scholarships and their requirements, as well as a link to the electronic application, can be found on the department scholarship page. Please note that this year all applications are submitted online.

]]>Truth tables are the basic elements behind the “thinking” power of electronic devices. Basic modules of semiconductor electronics are generally referred to as logic gates. These gates can make decisions based on the presented inputs (statements).

Typically, presenting the concepts of truth tables is a difficult task. Introducing logic gates and implementing a class project can not only help students to understand the importance of truth tables, but it also inspires them to create their own projects. The authors describe the basics of logic gates and how they can be used in teaching truth tables.

]]>Sage is a free mathematics software system licensed under the General Public License. Using a Python-based interface, Sage’s goal is to be an open source alternative to software packages such as Maple, Mathematica, and Matlab. In the workshop, an introduction to the Sage software and its different interfaces will be given using the IUP Sage server and hands-on Sage notebook activities.

]]>The first chapter, “Reform-Based Instruction in Korea: Looking over Its Promises to Discover Its Successes,” was coauthored with Jinho Kim (Department of Mathematics Education, Daegu National University of Education) and Jung Colen (Department of Curriculum and Instruction, Penn State University). This chapter introduces practices for successful implementation of reform-based instruction from the perspectives of the learner, the teacher, knowledge, instruction, assessment, and classroom culture. Moreover, this also examines mathematical and instructional practices before, during, and after Korea’s seventh National Curriculum and concludes with some implications to improve reform-based instruction.

Colen coauthored the other chapter, “Teaching and Learning Practice in Mathematics Classrooms: Focus on Statistics,” with Sanglyong Kim (Department of Mathematics Education, Daegu National University of Education), Seonghee Kim (Curriculum and Instruction, Arizona State University), and Jinho Kim (Department of Mathematics Education, Daegu National University of Education). This chapter introduces the practices of teaching and learning mathematics in Korea. It describes the content of the “probability and statistics” strand in the elementary school curriculum and considers some of its shortcomings. In order to overcome these shortcomings, the authors transform the fourth grade unit (“Broken Line Graph”) into the theme “Students Understanding Themselves.” In this unit, students collect their height and weight measurements, organize and represent data, and project them into the future. These lessons demonstrate students’ abilities to investigate the posed problems, to communicate their thinking, to summarize their findings, and to reflect upon the project and their metacognitions.

Jinho Kim, Inki Han, Joongkwoen Lee, and Mangoo Park edited the volume.

The award is presented to a mathematician or a mathematics educator from a public or private school, college or university, or industry who has made an outstanding contribution to mathematics education in Pennsylvania.

The award was presented at the PCTM Annual Conference in Harrisburg on October 18, 2012.

]]>The presentation reports on a student-focused comprehensive research project integrated in undergraduate introductory econometrics classes at IUP. Since 2000, approximately 150 IUP undergraduate students have completed these research projects. The assignment requires each student to conduct empirical research on a topic of his/her choice, write a formal paper formatted like a scholarly journal article, and give an oral presentation of the findings to the class. As a result of this project, students gain hands-on experience applying econometric techniques to real economic data and learn how to conduct independent research. The multiple benefits of the assignment for the professional development of IUP students as they apply for jobs and graduate school admissions are discussed.

]]>The 2000 presidential election provides an ideal backdrop to introduce the electoral voting system, the weighted voting system, and the Banzhaf and the Shapley-Shubik Power Indices.

]]>Del Valle earned a PhD in Applied Mathematics and Computational Sciences in 2005 from the University of Iowa, and a BS and MS in Applied Mathematics in 2000 and 2001, respectively, from the New Jersey Institute of Technology. She has worked on developing and analyzing mathematical models for the spread of infectious diseases, including smallpox, anthrax, malaria, HIV, and influenza, on a pandemic scale. She has also worked on social network analyses and modeling and simulation of large scale, agent-based simulations.

Dr. Del Valle will be giving three presentations:

1:25–2:15 p.m. in Pratt Auditorium

**Abstract:** Science, technology, engineering, and mathematics (STEM) are playing a key role in the development of new discoveries and meeting the challenges of this century. In this talk, I will present some examples of scientific advances made possible by the interaction between science and mathematics. In particular, I will describe the role of mathematics in epidemiology, climatology, biology, sports, and entertainment.

3:35–4:35 p.m. in Stright Hall, Room 327/329

**Abstract:** Pursuing a career in science has never been more timely, but also difficult due to the current economic uncertainty. In this talk, I describe my journey and provide some advice on the difficulties that lie ahead and the skills that you will need to succeed. Although my advice is geared toward women and minorities, many aspects of my talk are universal.

5:30–6:30 p.m. in Stright Hall Room 327/329

**Abstract:** Emerging and re-emerging infectious diseases are the leading cause of morbidity and mortality across the globe. Modeling efforts can help improve the effectiveness of public health interventions and minimize the population and economic impacts of an epidemic. In this talk, I will describe different mathematical and computational models used to simulate the spread of infectious diseases, including smallpox, influenza, and HIV and show the impact of intervention strategies on their spread.

Prior to coming to IUP, Reilly taught middle school mathematics for 10 years and high school mathematics for three years. She teaches courses for elementary and middle level education majors. Reilly’s research focuses on mathematics and writing, middle level mathematics education, and curriculum integration.

]]>The article stems from work Lattanzio did with Quan while Quan was a graduate student in the Mathematics Department.

For natural numbers k and n, where 2 ≤ k ≤ n, the vertices of a graph are labeled using the elements of the k-fold Cartesian product In×In× …×In.

Two particular graph constructions will be given and the graphs so constructed are called generalized matrix graphs. Properties of generalized matrix graphs are determined and their application to completely independent critical cliques is investigated. It is shown that there exists a vertex critical graph which admits a family of k completely independent critical cliques for any k, where k ≥ 2. Some attention is given to this application and its relationship with the double-critical conjecture that the only vertex double-critical graph is the complete graph.

]]>“Variational Methods in Materials Science and Image Processing”

Time: 1:25–2:15 p.m.

Location: Pratt Auditorium

Several questions in applied analysis motivated by issues in computer vision, physics, materials sciences, and other areas of engineering may be treated variationally leading to higher order problems and to models involving lower dimension density measures. Their study often requires state-of-the-art techniques, new ideas, and the introduction of innovative tools in partial differential equations, geometric measure theory, and the calculus of variations.

In this talk, it will be shown how some of these questions may be reduced to well-understood first order problems, while, in others, the higher order plays a fundamental role. Applications to phase transitions and to the equilibrium of foams under the action of surfactants, imaging, micromagnetics, thin films, and quantum dots will be addressed.

“Careers in Mathematics”

Time: 2:45–3:45 p.m.

Location: Stright Hall, room 226

Fonseca will speak to students about careers in mathematics.

“Variational Methods for Crystal Surface Instability”

Time: 4:00–4:50 p.m.

Location: Stright Hall, room 226

Using the calculus of variations, it is shown that important qualitative features of the equilibrium shape of a material void in a linearly elastic solid may be deduced from smoothness and convexity properties of the interfacial energy. In addition, short-time existence, uniqueness, and regularity for an anisotropic surface diffusion evolution equation with curvature regularization are proved in the context of epitaxially strained two-dimensional films. This is achieved by using the $H^{-1}$-gradient flow structure of the evolution law, via De Giorgi's minimizing movements. This seems to be the first short-time existence result for a surface diffusion type geometric evolution equation in the presence of elasticity.

Irene Fonseca is president-elect of SIAM, Mellon College of Science professor of Mathematics at Carnegie-Mellon University, and director of the Center for Nonlinear Analysis.

]]>This program will highlight any mathematics-related scholarly work of undergraduate and graduate students. All oral presentations will take place in Stright Hall.

]]>The talk will be aimed at a general audience, so students are welcome.

Influenza A virus (IAV) causes a respiratory disease and continuously evolves, producing new pandemic strains of varying phenotypes. These pandemics occur seasonally, with about 3 to 5 million cases annually and an estimated 250,000 to 500,000 deaths worldwide. An individual becomes infected by inhalation of virus particles, which infect cells of the respiratory tract. Upon infection, influenza virus triggers an immune response, which consists of a rapid innate response and a slower adaptive response. The dynamics of the immune response and virus/host interactions are highly complex. We will discuss strategies for mathematical modeling of influenza viral growth and the immune response, and show how mathematical modeling may be used to estimate biological parameters governing interactions between the virus and the host.

]]>Megan Agosti (Physics), Dane Alabran (M.S. in Applied Mathematics), Albert Harrison (M.S. in Applied Mathematics), and SaraJane Parsons (Mathematics) recently applied to various graduate programs.

]]>Professor John Henry Steelman retired at the end of the Fall 2011 semester after nearly 26 years in the Mathematics Department.

Steelman came to IUP as an associate professor in 1986 and was promoted to professor in 1992. His dedication to students, colleagues, and the university was widely known, and will be missed.

Steelman was a frequent contributor to the Problems and Solutions section of the *American Mathematical Monthly*. He played a leadership role in the High School Mathematics Competition held annually at IUP, for which he supervised the construction of scores of mathematics problems. He was also active in the Association of Pennsylvania State College and University Faculties.

Acting with the local Indiana Players is among his other interests.

]]>Each student presented a hands-on activity for teaching middle school mathematics. The students presenting with Dr. Walker were:

- Brandon Kochinsky, from Nicktown, Pa.
- Megan Labant, from Indiana, Pa.
- Antoinette Moeslein, from Pittsburgh, Pa.
- Derek Morf, from Annandale, N.J.
- Brianne Thomas, from Homer City, Pa.

Check back in late January 2012 for tutoring hours for the Spring semester.

]]>This talk is intended to be accessible to those without a background in combinatorics. Students are encouraged to attend.

Thirty years ago, three mathematicians made a conjecture for counting the number of n x n alternating sign matrices. Then they discovered that someone else already had seen those same numbers—but he had been counting a certain type of restricted plane partition. In the years since, many proofs and results have been found in each of these seemingly unconnected fields. We will follow the story of the conjectures, theorems, and proofs, including the surprising twist in 1996.

]]>The career panel will take place on Friday, December 2, 2011, from 2:30–3:30 p.m. in room 340 of Stright Hall. Light refreshments will be served.

The panelists include three recent graduates of IUP and a new faculty member:

- Kwasi Abrefa-Kodom (M.S. Applied Mathematics, 2010), who works for IBM
- Ben Jarrett (M.S. Applied Mathematics, 2010), who works for the Federal Energy Regulatory Commission
- Paul Rossman (B.A. Journalism, 2006, M.S. Applied Mathematics, 2008), who works for Sheetz
- John Chrispell (Ph.D. in Mathematical Sciences, Clemson University, 2008), who is an assistant professor of Mathematics at IUP

On Thursday, Dr. Famoye will speak on “Regression Models for Count Data” at 5:00 p.m. in Stright Hall, room 327.

On Friday, he will meet with interested students, where he will discuss and take questions on aspects of his career. This meeting will take place in Stright Hall, room 329, from 12:20 to 1:10 p.m.

Linear regression models have been found useful when the experimental observations follow the normal distribution. Quite often, experimental observations are count, and it is natural to assume that these observations follow a count discrete distribution instead of a continuous distribution. This talk will provide a survey of research work on modeling count data.

]]>The Mathematical Sciences Research Institute at Berkeley, Calif., will sponsor “Critical Issues in Mathematics Education: The Mathematical Education of Teachers” on May 11–13, 2011. The workshop will showcase materials and successful teacher education programs, examine the Common Core State Standards and its implications, and explore how mathematics education research can improve practice. The audience for the workshop includes mathematicians, mathematics educators, classroom teachers, and education researchers who are concerned with improving the teaching of mathematics and, in particular, the mathematical education of teachers.

University of Michigan will sponsor “IBL Workshop on Inquiry Based Learning” on May 21–25, 2011. Inquiry-based learning (IBL) has been highly successful both in mathematics and mathematics education environments. Via IBL, students actively participate in their mathematical education. They become adept at understanding and explaining mathematics.

This workshop will discuss IBL methods in a variety of settings. In particular experienced instructors will present on

- The Freshman Experience
- The Math Major Experience
- Math Education
- Assessment

Workshop participants will be prepared to present effective IBL style courses after the workshop. Participants will be connected to a mentoring support system to help them as they implement these ideas in their own institutions.

Presenters will come from a diverse set of institutions: California Polytechnic University, De Paul University, Kenyon College, Marshall University, University of Chicago, UCSB, University of Colorado, University of Michigan, and University of Texas.

]]>The colloquium will be on Wednesday, April 27, 2011, at 3:30 p.m. in Stright Hall, Room 202.

Penalized Regression procedures have become very popular ways to estimate complex functions. The smoothing spline, for example, is the solution of a minimization problem in a functional space. If such a minimization problem is posed on a reproducing kernel Hilbert space (RKHS), the solution is guaranteed to exist, is unique, and has a very simple form. There are excellent books and articles about RKHS and their applications in statistics; however, this existing literature is very dense. Our intention is to provide a friendly reference for someone approaching this subject for the first time.

This talk begins with a simple problem, a system of linear equations, then gives an intuitive motivation for reproducing kernels. Armed with the intuition gained from our first examples, we take the reader from Vector Spaces to Banach Spaces and to RKHS. Finally, we present some statistical estimation problems that can be solved using the mathematical machinery discussed.

]]>The minimum and maximum values in a random sample are two of the descriptive statistics reported by many types of statistical software. These are examples of *order statistics*.

In this talk, I will introduce some basic calculations involving order statistics for a continuous random variable, and then I will turn my attention to the Super 6, a defunct Pennsylvania Lottery game, and present an analysis of order statistics in the context of this game. As a part of this discussion, we will employ some inductive reasoning by examining patterns in Pascal’s Triangle, and then we will use math induction to prove our conjectures.

]]>Jung presented “Discrete Mathematics in the Elementary Grades” at the spring 2011 meeting of the Allegheny Mountain Section of the Mathematical Association of America at Clarion University of Pennsylvania on April 9.

At the 2011 Pennsylvania State System of Higher Education Mathematics Association conference, on April 2 at California University of Pennsylvania, she presented “Teaching Map Coloring to Elementary Students.”

These presentations shared an experience in teaching map coloring to a second-grade student and explored ways to incorporate discrete mathematics at the elementary grade level.

]]>Minimizing airplane turnaround time is an important objective of airline companies since it is used as a measure of airline efficiency. Passenger boarding time is an important factor for determining turnaround time. This is the factor for which airlines have the least control.

The focus of our study is to determine a way to decrease passenger boarding times by expanding upon past studies [1]. Using similar methods as the authors of [1], passenger and aisle interferences during airplane boarding were studied. It was determined that an outside-inside boarding strategy is the most efficient way to board the airplane. This differs from the results determined by [1], which suggests a reverse pyramid strategy. The difference in these results was attributed in part to the different usage of aisle interference penalties in the model.

]]>His research is an extension of the work he did for his thesis at IUP.

Baseball is a sport full of numbers and statistics. With a large sample size of a 162-game season, it also is a perfect atmosphere for advanced statistical analysis. Fewer than one thousand players competed at the Major League level this past season, but more than three thousand played in the minor leagues with the hope and ambition of making it to “the big show.” In reality, however, less than 10 percent of these players will actually accomplish that dream.

This talk contends that a probability can be determined for each player in the minor leagues that predicts that player’s chances of making it to the major leagues. Probabilities are computed using logistic regression.

]]>On Thursday, Dave will give a talk geared towards faculty entitled “Of Elephants, Fuzzy Dogs, and Teaching Backwards: A Story about Making Your Course Engaging.” This talk will be in Stright 302 from 3:30 to 4:30 p.m.

On Friday, Dave’s talk will be geared towards students. He will present “Dude, Just How Big IS Infinity?” in Stright 229 from 11:15 a.m. to 12:15 p.m.

Dave Sobecki is an associate professor in the Department of Mathematics at Miami University in Hamilton, Ohio. He earned a B.A. in math education from Bowling Green State University before continuing on to earn an M.A. and a Ph.D. in mathematics from Bowling Green State University. He has written or coauthored five journal articles, eleven books, and five interactive CD-ROMs.

Abstracts for both talks can be found below.

Abstract: The traditional method of teaching math goes something like this: Definition; Theorem; Example; Example; Example; Application. Many of us feel pretty comfortable with that—hey, it worked for us. But does it work well for the average student? I propose a backward method: starting with applications to introduce and motivate the math. When you start to think this way, it opens up a world of possibilities. I’d like to share some of my world of possibilities, as well as some other strategies I use to keep students involved in their learning.

Abstract: Everyone knows that infinity is pretty darn big, but just *how* big? In this talk, I’ll present scenarios that will lead us into answering difficult arithmetic questions like “What is infinity plus infinity?.” Along the way, we’ll learn about different types of infinity and how they apply to sets of numbers you’re familiar with. We’ll close with some perspective on a topic that most people should have some understanding of, but very few actually do: the amount of money that our government actually spends. It’s not infinite, but the sizes will probably surprise you when compared to numbers you’re more familiar with.

In 1977, Martin Gardner's “Mathematical Games” feature in *Scientific American* posed the challenge of factoring a 129-digit number (known as RSA-129). Using the resources available at the time, it was estimated that it would take 40 quadrillion years to factor this number. However, in 1994, Lenstra, et al., announced a factorization of RSA-129. Using many computers, it took them eight months to complete this groundbreaking calculation. They used a modified implementation of the Quadratic Sieve, which had been originally introduced by Carl Pomerance in 1982.

The goal of this talk will be to give a general overview of the Quadratic Sieve algorithm. Special attention will be given to the elementary number theory and linear algebra techniques used in the algorithm.

Undergraduate students are encouraged to attend! The talk is intended to be accessible to those who are familiar with the basics of modular arithmetic and linear algebra.

*Student Explorations in Mathematics* is an official publication of the National Council of Teachers of Mathematics and serves as a resource for students in grades 5-10, teachers, and teacher educators.

The article proposes a class of goodness-of-fit tests for assessing the parametric form of the baseline intensity process found in models used to analyze recurrent event data. These tests are based on a class of weighted empirical processes. Asymptotic properties of this class of weighted empirical processes are given for a sequence of Pitman alternatives. Test statistics are constructed as functionals of the weighted empirical processes. Optimal choices for the weight process are found for a class of chi-squared tests. Khmaladze's transformation is applied to the test statistic, and the asymptotic null distribution of the resulting transformation is given. Two data sets are used to illustrate the goodness-of-fit tests.

]]>In collaboration with the Carnegie Mellon Institute for Talented Elementary and Secondary Students (C-MITES), Dr. Yong Colen of the Mathematics Department will teach two courses at IUP.

C-MITES is a rigorous summer program in which gifted students are presented with challenging material that complements what they have studied in school.

More information about C-MITES is found on the Carnegie Mellon C-MITES website. The two courses are as follows:

Come stimulate your curiosity and develop mathematical problem-solving tools. Working individually and in small groups, you will encounter a variety of problem situations such as, “Why aren’t manhole covers square?” and, “Why isn’t the circular design optimal?” Solving atypical, perplexing problems, you will expand your originality of thought, intuitive reasoning, and mathematical knowledge.

June 20–24, 9:00 a.m.–4:00 p.m. (For students enrolled in grades 5–6 as of April 2011)

This course is designed for students who have taken a Pre-algebra or Algebra 1 course. You will explore how to make sense of more important algebraic concepts and examine why algebra has been a useful tool to solve meaningful problems. One particular focus of the course will be to analyze and utilize algebra in various forms—verbally, numerically, graphically, and symbolically.

June 27–July 1, 9:00 a.m.–4:00 p.m. (For students enrolled in grades 7–8 as of April 2011)

]]>This article combines the areas of theoretical graph theory and abstract algebra. This combination of mathematical areas gives fascinating results concerning the partitions of V(G) as they relate to a forty-two-year unsolved problem in graph theory posed by Erdős and Lovász.

In this article, for a graph G having chromatic number k, Dr. Lattanzio defines an equivalence relation on the set X of all proper vertex k-colorings of G. This leads naturally to an equivalence relation on the set P of all partitions of V(G) into k independent subsets of color classes. He then investigates the notion of a partition type and the algebra of types.

]]>Both presentations take place at 3:30 p.m. in Stright Hall, room 229.

In this presentation, k-dimensional n-square matrices are defined and subsequently matrix graphs arise naturally. Particular matrix graphs will be constructed. An application of two dimensional matrix graphs will be discussed as they provide the only known examples of graph admitting two completely independent critical cliques.

The construction of graphs admitting two completely independent critical cliques is generalized from two dimensions to three dimensions. Using 3-dimensional matrix graphs, we demonstrate the existence of an infinite family of graphs, the members of which admit three completely independent critical cliques. It is conjectured that a similar construction, using k-dimensional n-square matrices, can be used to prove the existence of a graph admitting k completely independent critical cliques.

Less than 1,000 players competed at the Major League level this past season, but more than 3,000 played in the minor leagues with the hope and ambition of making it to “the big show.” In reality, however, less than 10 percent of these players will actually accomplish that dream. This colloquium contends, using logistic regression, that a probability can be determined for each player in the minor leagues that predicts that player’s chances of making it to the major leagues.

Light refreshments will be provided.

Through the process of professional accreditation of schools, colleges, and departments of education, NCATE works to make a difference in the quality of teaching and teacher preparation today, tomorrow, and for the next century. NCATE’s performance-based system of accreditation fosters competent classroom teachers and other educators who work to improve the education of all P-12 students. NCATE believes every student deserves a caring, competent, and highly qualified teacher.

The National Council of Teachers of Mathematics recognized the IUP Mathematics Education program as having “a very strong content component. In the past three years, the 36 teacher candidates have passed the Praxis II test, scoring 136 or higher. Nine teacher candidates received recognition from ETS for passing in the top 15% of the field. The program also has a very strong education component with a very well designed and sequenced field experience component culminating with student teaching. An additional strength of the program is that the university professors for both the pre-student teaching courses and the supervisors for the student teaching are members of the Mathematics Department Faculty.”

Dr. Mary Ann Rafoth, dean of the College of Education, recognized the efforts of Dr. Janet Walker, who designed the program’s evaluation system, collected data over the past five years, and compiled the report. “I would like to commend Dr. Janet Walker, Secondary Math Education coordinator, for her hard work in preparing this excellent application,” Rafoth said. “You cannot earn better accolades than those given by NCATE.”

NCATE also selected the IUP Mathematics Education Program report to use as a sample for a successful program application at conferences and on their website. This will be used by NCATE to help other universities and teacher education programs prepare their own reports.

]]>In the early part of this millennium, it was predicted that two well-known games would be solved by the end of the decade: checkers and reversi (Herik, Uiterwijk, and Rijswijck 2002, 306). In 2007, the first half of this prediction became a reality when it was announced that, with perfect play, or the strategy which leads to the optimal outcome regardless of the response(s) of his opponent(s), either player in a game of checkers can force a draw. Sorting through the 5 x 1020 possible checkers positions required around-the-clock computing on, at times, up to 200 processors for nearly twenty years (Schaeffer et al. 2007, 1518). It currently appears unlikely that reversi, with an estimated 1028 possible positions and significantly more possible games than checkers (Allis 1994, 167-8), will be solved before the end of 2010.

Solving the game of reversi would be a multi-year effort with inherent extensive computing and storage requirements unavailable to the author of this thesis. It has, however, been said that a well-defined problem is half solved; the intent of this thesis is to define the characteristics of reversi in such a way that it could be solved given the proper resources. Results from the solution of a reduced form of the game show that equivalent positions can be generated at a reasonable processing cost to greatly reduce physical storage requireme

For memorial donations to the Mathematics Department, the family has requested funds be contributed to the Arthur G. Morrell Scholarship fund. Don and Wally Morrell (Art’s dad) were good friends, and since Don himself was a military man, the family thought it would be appropriate.

Checks should be made payable to The Foundation for IUP, and the memo line of the check should contain “Morrell 630142 in memory of Don Duncan.”
