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 […]

Development and Assessment of a Groundwater Sustainability Index in Climatically Diverse Groundwater Irrigated Regions in Nebraska (Civil Project)

The aim of this research was to evaluate the impact of regional change in ET on groundwater level changes and the assessment and development of a groundwater sustainability index for climatically diverse regions acrossNebraska during 2000-2014. Irrigation in the selected regions is predominantly supplied by groundwater. The hypothesis is that groundwater use can become sustainable if the regional evapotranspiration (ET) […]

DNA Based Electrolyte/Separator for Lithium Battery Application (Electrical Project)

In this study, we demonstrated the use of DNA-CTMA (DC) in combination with PolyVinylidene Fluoride (PVDF) as a host matrix or separator for Lithium based electrolyte to form solid polymer/gel like electrolyte for potential application in Li-ion batteries. The addition of DC provided a better thermal stability of the composite electrolyte as shown by the thermos-gravimetric analysis (TGA). The AC […]

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 […]

Design and evaluation of a Capacitively Coupled Sensor Readout Circuit, toward contact-less ECG and EEG (Electronics Project)

In modern medicine, the measurement of electrophysiological signals play a key role in health monitoring and diagnostics. Electrical activity originating from our nerve and muscle cells conveys real-time information about our current health state. The two most common and actively used techniques for measuring such signals are electrocardiography (ECG) and electroencephalography (EEG). These signals are very weak, reaching from a […]

Tremor Quantification and Parameter Extraction (Electronics Project)

Tremor is a neuro degenerative disease causing involuntary muscle movements in human limbs. There are many types of tremor that are caused due to thedamage of nerve cells that surrounds thalamus of the front brain chamber. It is hard to distinguish or classify the tremors as there are many reasons behind the formation of specific category, so every tremor type […]

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 […]
