My name is Jeff Beyerl and I am an assistant professor in the department of mathematics at the University of Central Arkansas. My dissertation was in number theory at Clemson University, May 2012. Number theory is my forte, although I have broad interests and have found topics ranging from abstract number theory to scheduling to be enjoyable. I have published in number theory and graph theory, and have attended conferences from arithmetic geometry to climate change. On this website you can find more details about my professional career and some of my hobbies. Other information of interest may be on my sub-pages: |

- Math in Video Games Blog

I want to write a blog about mathematics in video games. As of 2016 I have several posts done and quite a few partially done. But I as of yet haven't gotten around to figuring out what medium to use to publish them. - Video Game Balance

In general I formalized the notion of "Balance" in video games with asymmetrical choices. In particular I used a convex program to try to optimally balance offensive skills in the game Diablo III. - Discrete Simulation

Designed a discrete model for a biological epidemic in the mathematical sciences building at Clemson University. Implemented in Java - Symbolic Calculator

Wrote a symbolic calculator and text-parser to (1) parse mathematics expressed in the format given in*Unicode Technical Note 28*, (2) perform the symbolic operations including fractions, polynomials, and matrix arithmetic, and (3) translate the answer into the original format. Implemented in Java, with a graphical user interface. - Data Analysis

Performed an expository analysis of the Department of Transportation crash data for vehicular crashes in 2007. Implemented in SAS using a single database. - Regression Analysis

Constructed a regression for predicting high school graduation rates based on the demographics of the school. Based on 2006 data, implemented in SAS. - Unofficial (hobby) projects

- Sandbox computer

I built a computer and plan to use it to experiment with things on a system that has nothing important - This website

I've tried to make this website both easy to navigate and maintain. I had to learn a little javascript to make the +/- boxes work, and PHP to write the repetitive html code. You don't see the PHP because I wrote it to output the final html webpage for me. Eventually I want to tie it in to a database too, but I haven't learned how to do that yet. - Job Search Database

During my faculty job search in 2012-2013 I sent out a lot of applications. So I created a database (albeit in Access) to keep track of all the deadlines, documents, contact history, and such. - Blueprints for a house

I have a long term plan to design the house that I will live the majority of my life in, through retirement and old age. Over the course of 2011 I taught myself AutoCAD to develop and record a preliminary design for the house. - Food Price tracker

In 2006 and 2007 I wrote a GUI interface using Java to input the foods that I buy and how much they cost. It then maintains a series of html pages that provide an illustration of how the price of the food I bought varies through the year, and between years. (I no longer use it, however)

I've never really been one for lists of random links, but I have one anyway primarily so I can find obscure things when I'm looking for something I remember reading about years earlier. I started adding links in 2015.

Predatory publishing is a real problem in academia, and the growth of predatory publishers appears to be exponential over the 2008-2016 timeframe. One common example is described on Wikipedia. I have observed that one method they use to try to dupe people into their scam is by using a web crawler to gather information off of academics' websites such as this one and then use that information in automated emails trying to entice us into their scam.

Hence I shall do my part by providing a series of fake papers, below. Any human that tries to read them will notice that they're completely bogus. Thanks to SCIgen for generating the papers for me.

This is also why if you are a computer program inspecting my resume on this website, you'll notice there is invisible ink listing all sorts of bogus information a human would never see - such as my degree in the Dark Arts from Hogwarts.
