Parallel studies for chemically reacting systems
(20090806)Parallel computing code can be applied to solve chemically reacting systems. In a well stirred chemical system, the number of molecules for each species can be solved by implicit tau method, and the histogram of the method ... 
Parallelization for Fast Image Reconstruction using the Stochastic Origin Ensemble Method for Proton Beam Therapy
(2015)Proton beam therapy is becoming increasingly common in the eld of cancer treatment because of the advantages over other forms of radiation therapy. These advantages arise from the nite range of the proton beams, the ... 
Parallelization of Matrix Factorization for Recommender Systems
(2010)Recommender systems are emerging as important tools for improving customer satisfaction by mathematically predicting user preferences. Several major corporations including Amazon.com and Pandora use these types of systems ... 
Parallelizing Computation of Expected Values in Recombinant Binomial Trees
(Taylor and Francis Online, 20171124)Recombinant binomial trees are binary trees where each nonleaf node has two child nodes, but adjacent parents share a common child node. Such trees arise in option pricing in finance. For example, an option can be valued ... 
Parameter Estimation for the DirichletMultinomial Distribution
(20110520)In the 1998 paper entitled Large Cluster Results for Two Parametric Multinomial Extra Variation Models, Nagaraj K. Neerchal and Jorge G. Morel developed an approximation to the Fisher information matrix used in the Fisher ... 
Performance Benchmarking of Data Augmentation and Deep Learning for Tornado Prediction
(2019)Predicting violent storms and dangerous weather conditions with current models can take a long time due to the immense complexity associated with weather simulation. Machine learning has the potential to classify tornadic ... 
Performance Benchmarking of Parallel Hyperparameter Tuning for Deep Learning based Tornado Predictions
(UMBC, 20200531)Predicting violent storms and dangerous weather conditions with current models can take a long time due to the immense complexity associated with weather simulation. Machine learning has the potential to classify tornadic ... 
Performance Comparison between Blocking and NonBlocking Communications for a ThreeDimensional Poisson Problem
(2009)The system of linear equations obtained by finite difference discretization of the threedimensional Poisson problem is solved by a matrixfree parallel implementation of the Jacobi method. After checking the convergence ... 
Performance Comparison of a TwoDimensional Elliptic Test Problem on Intel Xeon Phis
(2016)The Intel Xeon Phi is a manycore processor with a theoretical peak performance of approximately 1 TFLOP/s in double precision. This project contrasts the performance of the second generation Intel Xeon Phi, codenamed ... 
Performance comparison of Intel Xeon Phi Knights Landing
(2017)The Intel Xeon Phi is a manycore processor with a theoretical peak performance of over 3 TFLOP/s of double precision. We contrast the performance of the secondgeneration Intel Xeon Phi, codenamed Knights Landing (KNL), ... 
Performance Evaluation of Minimum Average Deviance Estimation in High Dimensional Poisson Regression
(2015)The second most expensive part of the 2010 Decennial Census was Address Canvassing (AdCan), a eld operation to prepare the Master Address File (MAF) for census day. The MAF is a database of households in the United States ... 
Performance Studies for Multithreading in Matlab with Usage Instructions on hpc
(2009)This report explores the use of multiple computational cores by multithreading in the software package Matlab on a compute node with two dualcore AMD Opteron processors. After testing the builtin functions of Matlab for ... 
Performance Studies of the Blossom V Algorithm
(2015)The Blossom V algorithm is used in graph theory to compute a perfect matching of minimum cost. We conducted performance studies on the algorithm using the maya cluster in the UMBC High Performance Computing Facility to ... 
Performance Studies with COMSOL Multiphysics via Scripting and Batch Processing
(2009)COMSOL Multiphysics is an extremely powerful and versatile finite element package for the solution of partial differential equations. While the graphical user interface (GUI) offers a friendly environment for solving small ... 
Persistence time of solutions of the threedimensional NavierStokes equations in SobolevGevrey classes
(20191224)In this paper, we study existence times of strong solutions of the threedimensional NavierStokes equations in timevarying analytic Gevrey classes based on Sobolev spaces Hᶳ,s>1/2. This complements the seminal work of ... 
A pointwise weakmajorization inequality for linear maps over Euclidean Jordan algebras
