Approximately 2.2 million people in the United States depend on a wheelchair to assist with their mobility. Often times, the wheelchair user can maneuver around using a conventional joystick. Visually impaired or wheelchair patients with restricted hand mobility, such as stroke, arthritis, limb injury,... READ MORE
Statistical machine learning uses data to model a relationship between many parameters, or explanatory variables, and a response variable. The adaptive boosting algorithm is a machine learning method that can be used to model relationships of classification data. This method uses a weak base... READ MORE
Determining the mass of a vehicle from ground based passive sensor data is important for many security and traffic safety reasons. A vehicle consists of multiple dependent and independent systems that each respond differently to changes in vehicle mass. In some cases, the responses... READ MORE
Image classification and object recognition are some of the most prominent problems in computer vision. The difficult nature of finding objects regardless of pose and occlusions requires a large number of compute resources. Recent advancements in technology have made great strides towards solving this... READ MORE
The variability in demand across the planning horizon and the presence of heterogeneous workforces where workers learn and forget at different rates make the process of building and managing a workforce challenging. When integrating learning and forgetting functions of workers into workforce scheduling, the... READ MORE
Applications of optical remote sensing processes include environmental monitoring, military monitoring, meteorology, mapping, surveillance, etc. Many of these tasks include the detection of specific objects or materials, usually few or small, which are surrounded by other materials that clutter the scene and hide the...

The relationship between genetics and phenotype is a complex one that remains poorly understood. Many factors contribute to the relationship between genetic variations and differences in phenotype. An improved understanding of the genetic underpinnings of various phenotypes can help us make important advances in... READ MORE
Nanosphere lithography, a technique of generating hexagonally packed monolayers with nanospheres, has been studied and been shown to increase the efficiency of the devices such as light emitting diodes and solar cells. In this research, the fabrication of nanosphere lithography was explored with the aim... READ MORE
The adoption of Distributed Web Systems (DWS) into modern engineering design process has dramatically increased in recent years. The Engineering Design Guide and Environment (EDGE) is one such DWS, intended to provide an integrated set of tools for use in the development of new... READ MORE
Background: Electronic cigarettes are battery powered nicotine vaporizers built with a heating element that atomizes an e-liquid solution. Studies have been conducted to understand user nicotine exposure however, replicating realistic use patterns, puff topography, is necessary to conduct accurate emissions studies. Previous studies have... READ MORE
The carbon footprint of cellular base stations is continuously increasing, due to their large power consumption that accounts for more than 50 % of all of the cellular network infrastructure, and because of the large growth rate experienced by the cellular infrastructure. To address this... READ MORE
The grape industry relies on in situ crop assessment to aid in the day-to-day and seasonal management of their crop. In the case of soil-plant chemistry interactions, there are six key nutrients of interest to viticulturists in the growing of wine grapes: nitrogen, potassium,... READ MORE
Carbon nanotubes (CNTs) are an emerging class of nano-structured carbon materials which are currently being studied for applications which would benefit from their desirable electrical and mechanical properties. Potential benefits such as improved current density, flexure tolerance, weight savings, and even radiation tolerance have... READ MORE
A method for modeling the signal from cables and powerlines in Synthetic Aperture Radar (SAR) imagery is presented. Powerline detection using radar is an active area of research. Accurately identifing the location of powerlines in a scene can be used to aid pilots of... READ MORE
Staphylococcus aureus is a major cause of hospital-acquired infections. The multi-drug resistant nature of certain S. aureus strains makes the discovery of new drug targets for S. aureus vital. A newly discovered virulence factor from S. aureus was described as an ortholog of NagD from... READ MORE
With advancement in technology and increased breadth of requirements of customers, organizations have to deliver innovative products in a quick and efficient way to remain competitive. While there are many theories and approaches to innovation in products, few of them are quantitative in nature.... READ MORE
Moderate resolution remote sensing data offers the potential to monitor the long and short term trends in the condition of the Earth’s resources at finer spatial scales and over longer time periods. While improved calibration (radiometric and geometric), free access (Landsat, Sentinel, CBERS), and... READ MORE
