Benchmarking parallel implementations of cloud type clustering from satellite data
The study of clouds, i.e., where they occur and what are their characteristics, plays a key role in the understanding of climate change. The aim of this project is to use machine learning in conjunction with parallel ... 
Benchmarking Parallel KMeans Cloud Type Clustering from Satellite Data
(Springer, Cham, 20191008)The study of clouds, i.e., where they occur and what are their characteristics, plays a key role in the understanding of climate change. Clustering is a common machine learning technique used in atmospheric science to ... 
Block Cyclic Distribution of Data in pbdR and its Effects on Computational Efficiency
(2013)Programming with big data in R (pbdR), a package used to implement highperformance computing in the statistical software R, uses block cyclic distribution to organize large data across many processes. Because computations ... 
Calcium Induced Calcium Release with Stochastic Uniform Flux Density in a Heart Cell
(Society for Computer Simulation International (SCS), 20150726)Calcium is a critical component in many cellular functions. It serves many important functions such as signal transduction, contraction of muscles, enzyme function, and maintaining potential difference across excitable ... 
CAREERRELEVANT MATHEMATICS PATHWAYS: ON THE ROAD TO STUDENT SUCCESS
UMBC, a diverse public research university, has a reputation for producing highly capable undergraduate scholars. Unfortunately, many students place into mathematics courses at a lower level than those that offer degree ... 
A Chromatic Dispersion Estimation Method for Arbitrary Modulation Formats
(Optical Society of America, 20110506)Simulations show that a modulationformatindependent method for estimating chromatic dispersion from the phase of a coherentlyreceived signal at four frequencies can estimate 3000 ps/nm of dispersion to within 2% at an ... 
Cluster Computing using Intel Concurrent Collections
(2012)The Intel Corporation is developing a new parallel software and compiler called Concurrent Collections (CnC) to make programming in parallel easier for the user. CnC provides a system of collections comprised of steps, ... 
Clustering of Multidimensional Data Sets with Applications to Spatial Distributions of Ribosomal Proteins
(2013)Consider ribosomal proteins, each with a threedimensional spatial location. Proteins related to the cofactor phenotype may be randomly or nonrandomly distributed within the ribosome. To investigate this question, the ... 
Commutation principles for optimization problems on spectral sets in Euclidean Jordan algebras
(20200910)The commutation principle of Ramirez, Seeger, and Sossa proved in the setting of Euclidean Jordan algebras says that when the sum of a real valued function h and a spectral function Φ is minimized/maximized over a spectral ...
