Program goals and structureThe Master's Degree Program in Applied Mathematics is specially designed to prepare graduates for a successful career in today's industrial/business world. Accordingly, the program is structured into the following three components:a core of graduate courses in applied subjects within the Department of Mathematics and Statistics;a selection of advanced courses in other departments including, but not limited to, these;a group project in which an applied scientific problem is undertaken in a colloborative effort.

The graduate courses in the Department concentrate on Analytical Methods, Numerical Methods, and Probability/Statistics.

The elective courses outside the Department are determined depending on each student's interests and preparation.

In recent years, they have been chosen from Computer Science, Engineering (Industrial, Mechanical, Electrical), Physics, and Management Science A JavaScript display engine for mathematics that works in all browsers. MathJax™ uses CSS with web fonts or SVG, instead of bitmap images or Flash, Code and TeX commands to get a pop-up that allows you to copy the math source American Mathematical Society Society for Industrial and Applied Mathematics .

These courses expose the student to the use of practical mathematical tools by scientists and engineers. The group project is the most novel component of this program.

It is intended to emulate industrial teamwork on a large, technical problem. Through the combined efforts and diverse talents of the group members, a mathematical model is developed, a computer code is implemented, and a final report is written.

In the process, the students learn how to start solving a new and hard problem, how to make a professional presentation of their work, and how to collaborate effectively with their coworkers. Student experiences and employmentHow is student life in the program? A comradery develops naturally among the students through their common coursework and the group project class, which meets weekly as a seminar and requires joint work outside class.

There are around ten students in the program in any given year. This size allows the students and the faculty to interact easily and frequently.

Also, the second-year students often share their experiences and contacts with the first-year students. Where do the graduates go? While a few find the program useful for developing their mathematics prior to pursuing other advanced degrees, most graduates find jobs in industry.

Typically, these jobs are in high-technology firms, often falling under the label of software development. Some recent graduates are employed by large, well-known companies: DEC, GTE, Hewlett-Packard, MIT Lincoln Labs, Pfizer.

Others work for smaller, local firms, such as Artios (Ludlow, MA) and Amherst Process Instruments (Hadley, MA). How do the graduates fare on the job market? It appears that many employers prefer to hire candidates having strong mathematical training together with good programming skills, rather than those with other, more specialized, degrees.

And, indeed, all the recent graduates from the program have secured good jobs upon completion of the program. What do the recent graduates have to say? Feedback from our graduates underscores the value of program, and the group project in particular, as preparation for the workplace. Here are a few examples of their comments:A 1993 grad now at Lincoln Labs writes, "One thing I would like to mention is that even though I may be using more computer skills than math, I feel that my math background has helped a lot.

When I was hired, my boss told me that she preferred someone with a math background who could program than a computer science major. Also, the applied math group project is a great idea because it teaches you to work as a group and prepares you for the "real world". "One of our 1994 alumni, who worked for a while at Fuji Capital Markets Corporation before returning to school, recalls, "Well I remember some words from my boss at FCMC : He told me that, 'A good background in mathematics and programming makes you a very valuable person for an Investment bank or a Capital Markets firm like Fuji Capital Markets.

If you combine both and have good conversational skills, that's exactly what employers are looking for.

' And that is exactly what we tried to learn in the Master's Program : get a thorough math background, learn to program and communicate. "An alumna from 1995, now working at GTE, states, "I think the best selling point is the project.

Not so much in terms of what the project is about, but rather the fact that you're working in a group where you have to deal with people not getting their portion of the project done, and project management issues. The team aspect is emphasized a lot at GTE and also I think in other companies.

The C coding is also very important; even little things like the RCS configuration management tool are good things to talk about (We're using one now called ClearCase, and tho' I didn't know exactly how to use it, at least I knew the principles behind why we needed such a thing. "A 1994 graduate reports, "I am currently a Statistician/Quality Engineer for the Hewlett-Packard Company. The Applied Math Program at UMASS was great for me.

I was able to choose many classes that built on my previous engineering degree.

The faculty at UMASS are also very supportive and are available for the students. I never had a problem trying to get advice on any matter.

In addition, the faculty realizes that students will be looking for a job after the program and they give the students many opportunities to make contacts and explore various professional paths. "A 1990 alumna who later received her PhD in meteorology writes, "The best thing about the applied math program is the solid theoretical background it gave me and the 'hands-on' application of that knowledge in a project.

I also enjoyed enormously the course I took outside the department in fluid dynamics, which set the foundation of my current research work. "Group projectsEach year a group project is completed by all of the current students.

In a sense, this project class is the organizing experience for the students in the degree program. In addition, it serves as the thesis component of the M.

The second-year students are expected to take a leadership role in the project, along with the two faculty members who guide it.

### Applied mathematics m.s. program | department of mathematics

The class meets as a weekly seminar throughout the academic year, although most of the real work occurs outside the classroom. The projects from recent years are described briefly below.

More details can be found at our Department Newsletters2015-16: Non-transitive Systems in Grasslands This year’s Applied Math Master's Project modeled the non-transitive interactions between three plant species in a prairie and explored the effects that urban development would have on species survival and co-existence. In a transitive system, if A defeats B and B defeats C then A defeats C; a non-transitive system is one that does not follow these rules. The prototypical example is the game of Rock-Paper-Scissors (RPS), where Paper covers Rock, Rock crushes Scissors, and Scissors cuts Paper.

Mathematically, non-transitive systems (often called RPS games) have been examined using discrete and continuous techniques and applied to model multi-player interactions in fields such as biology, economics, and social networking. 2014-15: Uncertainty Quantification: The Story Begins This year’s Applied Math Masters project utilized the emerging field of uncertainty quantification to focus on a topic of concern to human health: developing a Susceptible-Infected-Removed model (SIR) for forecasting the spread of dengue hemorrhagic fever (DHF).

2013-14: From Atomic Physics and Materials Science to Financial Mathematics and Beyond This year the Applied Mathematics Masters’ Program tackled a diverse variety of themes in the context of its yearly project: Bose-Einstein condensates in atomic physics; granular crystals in materials science; and deterministic (and potentially chaotic) models of supply-demand-pricing and inflation in financial markets. 2012-13: Multi-Agent Models This year the Masters students in the Applied Mathematics program undertook a multi-faceted project related to the broad theme of Multi-Agent Models.

First, it offered an opportunity to model the collective behavior of complex systems arising in a range of different disciplines.

In particular, three subgroups of the students studied dynamical systems from physical chemistry, biology, and finance. Second, this theme demanded a computationally intensive approach, and the students themselves expressed a desire to use the project to push the limits of their abilities as computational modelers.

2011-12: Power Grids and Energy Transmission Energy has become an important issue across the whole spectrum of our society. Overall electricity production, one of the most important forms of energy, is often used as an indicator whether a country is industrialized or non-industrialized.

The power grids used to transfer electricity from the generators to consumers have a tremendous scale and are becoming ever more complicated as more power plants are built to meet the ever increasing demand. This year the students in the Applied Math Master’s Degree Program worked on three different projects that deal with three different aspects of power grids and energy transmission.

2010-11: Numerical Optimization of Airport Traffic For this year’s group project in applied math, the students modeled the efficiency of airport taxi way operations, with the aim of improving the scheduling of departing and arriving flights at a busy airport. This problem was suggested by a former graduate from our department, Richard Jordan (Ph.

, 1994), who is currently working for the MIT Lincoln Laboratories.

Rich’s group in the Lincoln Lab is under contract from the FAA to update various aspects of airport operations by means of modern automation. 2009-10: Microscopic Traffic Flow Modeling, and Compressive Sampling In the past year, the Applied Mathematics Masters students were divided into two groups and worked on two separate projects.

The first group worked on a project about “Compressive Sampling,” which is a state-of-the-art technique to compress data during acquisition. The basic idea goes back to the 1970s, when seismologists first use the reflected waves to construct an image of the Earth’s interior structure.

But the field exploded around 2004 after David Donoho, Emmanuel Candes, Justin Romberg and Terence Tao discovered that the minimum number of data needed to reconstruct an image is less than that required by the famous Nyquist-Shannon criterion. The second group worked on a project of Microscopic Traffic Flow Modeling.

Different from macroscopic models, which treat traffic flow as an effectively one-dimensional compressible fluid, microscopic traffic models are built up from the minute level of individual cars and the interactions between them. The car-following model is one such model based on the stimulus-response mechanism — the following car takes actions like acceleration or deceleration whenever there is stimulus from the leading car, like a change of relative speed or headway.

Ideally, models of this kind should be able to reproduce common traffic phenomena, such as stop-and- go, platoon diffusion, or spontaneous congestion. In practical situations they could be used to predict traffic conditions on major roads and to aid traffic control procedures.

2008-09: Modeling Climate Change At first sight, there is no easy entry point for mathematical modelers into the extremely complex subject of climate dynamics. State-of-the-art climate predictions are based on elaborate numerical models that attempt to include all relevant physical processes in the entire Earth system.

These numerical simulators, which grew out of weather-prediction technology, are generically called GCMs, meaning General Circulation Models, although nowadays perhaps Global Climate Models is a more appropriate term. Their governing equations incorporate the circulation of the atmosphere as well as its radiative physics and chemistry (carbon dioxide, ozone, aerosols), the circulations of the oceans and coupling through the hydrosphere (water vapor, clouds, glaciers, sea ice), and even aspects of the biosphere (forests, soils, marine biota).

Models with this level of complexity take decades to develop, test, and tune, and they are very expensive to run. Moreover, the results and predictions that they produce are often quite hard to interpret, especially if the goal is to identify a particular mechanism and its effects.

2007-08: Cancerous Tumor, and Data Compression This year, students in the program worked on two projects. In the first project they looked at models of blood vessel growth towards a cancerous tumor.

A critical question for a patient diagnosed with cancer is whether the disease is local or has spread to other locations. Cancer cells penetrate into lymphatic and blood vessels, circulate through the bloodstream, and then invade and grow in normal tissues elsewhere.

This mechanism of spreading is called metastasis. Its ability to spread to other tissues and organs makes cancer a life-threatening disease.

Hence, there is naturally a great interest in understanding what makes metastasis possible for a malignant tumor. One of the key findings of cancer researchers studying the conditions necessary for metastasis is the fact that the growth of new blood vessels is critical in this respect.

In the second group project, the applied math studied data compression.

As with any communication, compressed data communication is useful only when the sender and receiver understand the coding scheme.

Compression is useful because it reduces the amount of space required for storage of the original data. On the other hand, compressed data must be decompressed in order to be used, and the additional processing could be harmful to some applications.

For example, a compressed video may require expensive hardware for the video to be decompressed fast enough to be viewed while it is being decompressed. 2006-07: The Mathematics of Climate The group worked on mathematical models of global climate.

The first person in history to publish a scientific paper on the physical principles that underlie climate — namely, the overall effect of solar radiation and its interaction with the Earth’s surface and atmosphere — was the famous mathematician Joseph Fourier. In the 1820s the father of the heat equation asked himself how it is that the Earth maintains an equilibrium temperature and what that temperature should be.

He first wondered why the Earth is not much hotter than it is, given that it is continually heated by the Sun. He realized that the Earth balances the solar radiation it receives by emitting lower frequency (infrared) radiation back into space.

But then his calculations suggested that the equilibrium temperature should be below freezing worldwide. The discrepancy lay in the fact that some gases in the atmosphere absorb the reflected radiation even though they are almost transparent to the solar radiation.

Of course, these are the greenhouse gases, principally water vapor and carbon dioxide. Although science was much too primitive in Fourier’s time for him to make a thorough analysis, his simple picture of the key processes has stood the test of time, and today it underlies the urgent debate on global warming.

2005-06: The Google Search Engine and the Mechanics of Human Locomotion The group worked on two projects. The first project was to model the search engine Google.

After people type keywords in Google, it prepares a list of websites associated with those keywords. By applying the power method in numerical analysis, the students were able to simulate the page-rank processing of a network.

They wrote a program, called a webcrawler, that crawls the internet site by site to determine how sites are interconnected. This created a network of 60,000 sites containing the Department of Mathematics and Statistics and its connected sites.

The students then applied the page-rank algorithm to this network. The students also applied the same algorithm to other topics such as developing a ranking system of US airports that would help determine which airports are the most important according to the numbers of passengers.

Once again using the power method and applying it to an actual data set obtained from the Bureau of Transportation, the students concluded that Dallas/Fort Worth International Airport is the most important airport in the US. Undertaking this project involved input from many academic areas. The students first had to understand the physiology of the leg as well as the mechanics of how the leg moves and interacts with various forces during running.

As they learned, the running process can be broken down into two phases. The stance phase is the period of time when the foot is still in contact with the ground, and the flight phase is the period of time when the foot and the body are in the air.

Each phase is governed by a different set of equations derived from Newton's laws of motion. The stance phase is described by three second-order differential equations while the flight phase is described by the equations for common projectile motion found in physics.

The students solved the coupled differential equations for the two phases numerically in order to simulate running. 2004-05: Pattern Formation, Tumor Growth and Turing Instability The spots and stripes which occur on plants and animals is modeled by the group.

The model is based on Turing instability or diffusion driven instability. A coupled pair of partial differential equations are used to model the pattern formation.

These equations are studied analytically to understand when instabilities will occur. The equations are then solved with a finite difference method numerically in different domains with varying parameters producing spots, stripes and combinations of the two.

The model is based on the tumor releasing a chemical(TAF) and using this chemical to recruit blood vessels to proliferate in its direction and eventually vascularize the tumor.

The model involved a partial differential equation for the chemical and one for the blood vessels. The equations were solved with a finite difference method numerically.

2003-04: Traffic Flow with Cellular Automata and Kinetic Models The group looked at different models for simulating traffic flow.

The primary model was one based on cellular automata. This model uses a finite set of vehicles with a finite set of rules governing their interaction.

The group showed that one can predict the mean velocity of a collection of vehicles depending on the density Best website to purchase a case study 33 pages British single spaced Platinum Weconnect should i order a custom presentation mathematics Junior single the top attributes of small and write me a custom paper applied mathematics .

One and two lanes were modeled along with stop lights and ramps.

The kinetic model produced solutions similar to the cellular automata which the differential equation is not capable of. 2002-03: Modeling of the Kidney and Lungs The regulation of sodium chloride in the kidney is modeled.

Each kidney contains over one million nephrons, the basic functional unit of the kidney. Each nephron regulates the composition of sodium chloride amongst other things.

The transport of sodium chloride in the loop of Henle, which is part of the nephron, is modeled with a partial differential equation. Using analysis, the partial differential equation is studied to understand when stable and unstable solutions might occur.

The equation is solved numerically using the Lax-Wendroff method. The computed solutions exhibit oscillations in the sodium concentration in time as is predicted by the analysis.

The group also worked with a research pulmonologist at Bay State Medical Center looking at the amount of carbon dioxide exhaled in healthy patents and patents with asthma versus time.

The group tested different methods for removing the noise from the data(smoothing the data). The group proposed several good methods that the pulmonologist could use in his work.

2001-02: Artificial Neural Networks1999-00: Modeling and visualizing human movement via mechanics and optimal control Image(s) from this project:1998-99: Quasi-geostrophic turbulence modelling using pseudospectral methods The objective of this project is to develop a mathematical model for forcasting atmospheric pressure patterns. The common assumption is made that the atmosphere can be modelled as an incompressible fluid.

The laws governing atmospheric pressure changes are then described using a Navier-Stokes equation in a rotating coordinant frame. Solutions to this nonlinear partial differential equation are obtained numerically, by means of pseudospectral method.

Image(s) from this project:1997-98: Macroscopic modelling of traffic flow Traffic flow is modelled through a hydrodynamic analogy, and the resulting nonlinear hyperbolic partial differential equation is solved numerically. In addition, on-ramps, off-ramps, and bottlenecks are modelled, and these complexities also are implemented in the computer simulation program.

Then, in order to model a two lane highway, the concept of lane changing is examined. A model of lane changing from the literature is discussed, and it is argued that this formulation is incorrect.

Moreover, a modified lane changing model is presented, and its validity is supported by the results of several simulations, again performed through the numerical solution of the governing differential equation. Finally, in order to illustrate the interrelationship between the effects of ramps and bottlenecks and the process of lane changing, results are presented for simulations which model ramps and bottlenecks along a two lane highway.

Image(s) from this project:1996-97: Monte-Carlo simulation of turbulent atmospheric diffusion The physical and mathematical diffusion of particles through a turbulent velocity field was calculated via two methods, a Random Eddy Model and Fourier Spectrum Model. The Random Eddy algorithm simulates a lattice of Rankine vortices; the Fourier Spectrum code utilizes a sum of sine and cosine terms to approximate the stream function of the turbulent velocity field.

Spatial correlation experiments were performed to ensure appropriate behavior for the moving particles, as well as parameter choices. Simulations of particle emanation from a smoke stack were also performed.

Image(s) from this project:1995-96: Acoustic radiation and propagation The sound field of a planar generator of general shape and/or mode was calculated by using a surface integral representation of the solution to the governing Helmholtz equation. Comparisons were made with some classical formulas available either in simple, symmetric cases, or in asymptotic regimes.

Interesting interference patterns in the sound intensity nearby the radiator were detailed over a range of frequencies and generator characteristics. The directivity of these sound generators was also studied.

Image(s) from this project:1994-95: Models of convective turbulent diffusion The steady-state concentration field of a pollutant introduced into a flowing, turbulent atmosphere was analyzed. A finite-difference method (alternating direction implicit) was implemented to solve the variable-coefficient diffusion equation in three dimensions, under a parabolic approximation in which the downstream variable is time-like.

The plume formed by a source was computed and displayed graphically for various sheared wind-flow conditions. Image(s) from this project:1993-94: Optics analysis The design of a lens system was tackled using a direct numerical approach based on ray-tracing for the geometrical optics.

Optical properties (focussing, magnification) of various instruments (simple telescopes, microscopes) were examied by computing the three-dimensional pencils of rays, without the classical paraxial approximation. Then the aberrations (spherical, coma, astigmatism, .

) were quantified numerically, and an optimization code was used to vary the lens system parameters so as to minimize a given aberration. Image(s) from this project:1992-93: Spectral computations in fluid dynamics The behavior of a two-dimensional viscous fluid was simulated by a direct numerical computation using a pseudospectral method.

First, some simpler one-dimensional codes were written for the Burgers and Korteweg-DeVries equations, and some wave interaction phenomena governed by these equations were studied. Then, the full code for a Navier-Stokes flow in two dimensions was implemented, and various vortex interactions were displayed.

Some assignments will be in Python and some in C++. COMPSCI 687: Reinforcement Learning This course will provide an introduction to, and comprehensive overview of, reinforcement learning. In general, reinforcement learning algorithms repeatedly answer the question "What should be done next?", and they can learn via trial and error to answer these questions even when there is no supervisor telling the algorithm what the correct answer would have been.

Applications of reinforcement learning span across medicine (How much insulin should be injected next? What drug should be given next?), marketing (What ad should be shown next?), robotics (How much power should be given to the motor?), game playing (What move should be made next?), environmental applications (Which countermeasure for an invasive species should be deployed next?), and dialogue systems (What type of sentence should be spoken next?), among many others. Broad topics covered in this course will include: Markov decision processes, reinforcement learning algorithms (model-based / model-free, batch / online, value function based, actor-critics, policy gradient methods, etc.

), hierarchical reinforcement learning, representations for reinforcement learning (including deep learning), and connections to animal learning. Special topics may include ensuring the safety of reinforcement learning algorithms, theoretical reinforcement learning, and multi-agent reinforcement learning.

This course will emphasize hands-on experience, and assignments will require the implementation and application of many of the algorithms discussed in class. PREREQUISITES: COMPSCI 589, or COMPSCI 689, or COMPSCI 683, with a grade of C or better.

Familiarity with an object oriented programming language is required (assignments will use C++, but familiarity with C++ specifically will not be assumed). COMPSCI 688: Probabilistic Graphical Models Probabilistic graphical models are an intuitive visual language for describing the structure of joint probability distributions using graphs. They enable the compact representation and manipulation of exponentially large probability distributions, which allows them to efficiently manage the uncertainty and partial observability that commonly occur in real-world problems.

As a result, graphical models have become invaluable tools in a wide range of areas from computer vision and sensor networks to natural language processing and computational biology. The aim of this course is to develop the knowledge and skills necessary to effectively design, implement and apply these models to solve real problems.

The course will cover (a) Bayesian and Markov networks and their dynamic and relational extensions; (b) exact and approximate inference methods; (c) estimation of both the parameters and structure of graphical models. Although the course is listed as a seminar, it will be taught as a regular lecture course with programming assignments and exams.
