Deposition Control for Electrospun Fibers (Electrical Project)

Electrospinning (ES) is a process for fabricating polymer fibers that have diameters that range from tens of nanons to hundreds of microns, which has been studied for over 100 years. These fibers have been studied in applications such as: the enhancement of mechanical properties including increased sensor sensitivity and increased tensile strength, filtration enhancement, drug delivery systems, and as a […]

Clinical Assessment for Deep Vein Thrombosis Using Support Vector Machines: a Description of a Clinical Assessment and Compression Ultrasonography Journaling System for Deep Vein Thrombosis Using Support Vector Machines (Computer/Biomedical Project)

This project describes a journaling system for compression ultrasonography and a clinical assessment system for deep vein thrombosis (DVT). We evaluate Support Vector Machines (SVM) models with linear and radial basis function-kernels for predicting deep vein thrombosis, and for facilitating creation of new clinical DVT assessment. Data from 159 patients was analysed, with our dataset, wells Score with a high […]

Laboratory and Full Boom-Based Investigation of Nozzle Setup and Restriction Effects on Flow, Pressure and Spray Pattern Distribution (Civil Project)

Pesticide application is an integral part of crop production and ground-based agricultural boom sprayers are used extensively to apply pesticides to the crop canopy or soil surface across millions of acres in the United States. Efficient application is necessary to minimize costs and limit adverse environmental impacts. Errors in flow rate and system pressure measurements may cause as-applied maps to […]

Design and Evaluation of Pediatric Gait Rehabilitation Robots (Mechanical Project)

Gait therapy methodologies were studied and analyzed for their potential for pediatric patients. Using data from heel, metatarsal, and toe trajectories, a nominal gait trajectory was determined using Fourier transforms for each foot point. These average trajectories were used as a basis of evaluating each gait therapy mechanism. An existing gait therapy device (called ICARE) previously designed by researchers, including […]

Development of Mobile-based Hand Vein Biometrics for Global Health Patient Identification (IEEE Computer Project)

For many health services in developing countries, patient identification is a fundamental need. In countries where no standard form of identification is available, this problem is exacerbated by a lack of literacy and also frequent errors in spelling and consistency. To address this need, we implemented two low-cost hand vein scanner devices for use with mobile devices. The first scanner […]

A Prototype for Blood Typing Based on Image Processing (Computer/Biomedical Project)

This paper presents a new methodology for blood phenotyping based on the plate test and on image processing techniques to determine the occurrence of agglutination (between blood sample and reagent). A portable device for ABO-Rh blood typing and blood phenotying that automates all the analysis procedure, including mixture/centrifugation, reading and interpretation of results is presented. The system was tested with […]

Control and Modeling of Plant Growth: A Versatile System for Mineral Nutrient Addition and Feed-back Monitoring (Electronics/Biotechnology Project)

Studying plants under controlled environmental conditions is a key component of current research. This thesis concentrates on the study of plant growth under nutrient-limiting conditions. The first objective is the design and construction of a prototype of a system which is able to supply nutrient solutions of prescribed time-dependent concentration to laboratory plants. The system, once configured via a PC, […]

Plaque Identification using Automated Image Enhancement (Computer/Biomedical Project)

Image enhancement is a task of applying certain transformations to an original image for obtaining output image visually more pleasant, more detailed, or less noisy. The transformation usually requires interpretation and feedback from a human evaluator for the output result image. In this project we introduce automatic image enhancement techniques which are helpful in plaque identification. Plaque is accumulation of […]

A method for Identification of Putatively Co-regulated Genes (Computer/Biomedical Project)

The genomes of several organisms have been sequenced and the need for methods to analyse the data is growing. In this project a method is described that tries to identify co-regulated genes. The method identifies transcription factor binding sites, documented in TRANSFAC, in the non-coding regions of genes. The algorithm counts the number of common binding sites and the number […]

Modeling of the arterial system with an AVD implanted (Electrical/Biomedical Project)

The number of patients that are waiting for heart transplants far exceed the number of available donor hearts. Left Ventricular Assist Devices are mechanical alternatives that can help and are helping several patients. They work by taking blood from the left ventricle and ejecting that blood into the aorta. In the University of Louisville they are developing a similar device […]
