The design of a knee mounted energy harvesting device for USB charging was investigated. With the current longevity issues of lithium batteries in portable electronics and the reliance for consistent access to a standard electrical socket for charging, a need for a portable and sustainable energy source was identified. Human biomechanical energy from movement was identified as an emission-free and...
Water scarcity affects 1.2 billion people on a global scale, representing nearly one fifth of the human population. In some regions, current water sources are being depleted faster than they are renewed and the majority of this depletion is being used for irrigation and agricultural purposes. At any given time, the atmosphere contains 3400 trillion gallons of water vapor, which would be enough to...
Nitrates, phosphates, and many other anionic chemical species are among the most problematic and widespread contaminants in water sources. Currently, technologies for removing them in water involve biological and physico-chemical processes. In this study, we test the extent to which the cationic protein from Moringa Oleifera (MO) seeds can effectively sequester anionic contaminants in water. The protein...
Untreated surface water and groundwater are the primary sources of drinking water in many parts of the world, particularly in low-income regions. In these communities, the availability of low-cost water treatment technologies is especially critical in reducing incidences of waterborne diseases. In the present study, we explore the use of Moringa seeds for disinfecting contaminated water. Moringa seeds...
The importance of the many sources of risk to the supply chain has been recognized by the practitioners and leadership in this sector of the economy. Cyber security is paramount to the success of the supply chain sector, which constitutes a safety-critical system for the U.S. and global economy. The diverse consequences from a malevolent attack could adversely affect inventory, product quality, time...
Traffic congestion is one of the most pressing issues in the US highway transportation systems and is a primary concern for motorists nationwide. Not only does it pose a psychological strain on commuters, it also results in monetary losses through wasted working hours and heightened transportation costs. The Hampton Roads metropolitan area is one of the most congested urban regions in the Commonwealth...
Over the past decade, numerous studies have estimated the economic impacts of a variety of disruptions. Most of these studies are based on macroeconomic models that quantify the direct and indirect economic losses from a disruption. Direct economic losses occur due to damaged facilities or when consumers change their purchasing behavior because of the disruption. Indirect economic losses occur when...
The injection of stratospheric aerosols is an effective and feasible solution to addressing the current speed the global climate change has taken. The current international goal that this research has set as a target is to remain below two degrees Celsius above preindustrial temperatures. With the lack of political will in addressing global warming, an initiative must be made to stabilize the global...
Infiltration of the global airplane production supply chain could have catastrophic impacts on flight safety. Thousands of suppliers feed specialized components and materials to only a few large airplane manufacturers. One compromised node in the supply chain could significantly damage the world's commercial airline fleets. A methodology and two models are proposed to detect and assess risk points...
The anterior cruciate ligament is a main stabilizer between the tibia and femur. Tearing it causes loss of mobility and need for surgery. There is a 13% chance for a National Collegiate Athletic Association athlete to tear their anterior cruciate ligament each year. The recovery process can take up to 9 months, about a quarter of a collegiate athlete's career and 44% of those who complete rehabilitation...
To effectively design, deploy, operate, and retire its fleet of boats, the U.S. Navy requires data-driven testing and evaluation of 50-foot boats throughout the lifecycle of the boat design. This project involves the development of an inexpensive, stand-alone instrumentation box capable of gathering motion, GPS, and engine data for the evaluation of boats and boat designs used by the U.S. Navy. Analysis...
Variable frequency drives (VFD) enable control of the speed of three phase motors which allows the motor to be operated with variable current inputs. This technology can be used in Heating, Ventilation and Air Conditioning (HVAC) systems to lower fan operating speeds, reducing energy consumption. The client has expressed a need for a more effective means of control for the operation of their two air...
With continuing developments in automation, robots will begin to supplement tasks that ordinary humans find dull, dirty or dangerous. In situations where robots and humans are interacting or working together, humanoid robots can better navigate human environments and make humans more comfortable with their appearance. Until recently, most humanoid robots were custom-made and designed for one specific...
The Internet of Things (IoT) has become a popular subject in the technology industry and will soon reach the popularity level of smartphones. With the rapid technological advancements of sensors, Wireless Sensor Networks (WSNs) has become the main technology for IoT. We investigated the security of WSNs in an environmental monitoring system with the goal to improve the overall security. We implemented...
Videology, an online video advertising company, is often unable to obtain gender information about incoming online advertisement requests. They purchase aggregate gender statistics on groups of requests from a third party. This project explores creating groups of requests in which at least 80% of the advertisement requests have the same gender using: 1) traditional clustering algorithms, 2) iterative...
The research detailed in this paper seeks to develop an algorithm to optimally select apps to be pre-installed on newly purchased Verizon smartphones. The research focuses on using consumer data sets provided by Advertising.com, a subsidiary of Verizon Communications, to identify and target consumers that are more likely to use pre-installed apps on their smartphones. Advertsing.com hopes to use these...
In today's technological era, the volume of data being processed on a daily basis is growing exponentially. The influence of data is affecting consulting firms and the expectations client companies have of consultants. Consulting firms are expected to not only use their client's data but also to leverage open source data and data from other firms that can help address the clients' needs. Manually...
The Centers for Disease Control and Prevention (CDC) estimate that more than two million people are sickened every year with antibiotic-resistant bacterial infections, and at least 23,000 die as a result of these infections in the U.S. alone. Carbapenem-resistant Enterobacteriaceae (CRE) are a particularly important subgroup with the ability to share genetic material, including the gene responsible...
This study focuses on predicting the risk of occurrence of serious but treatable complications and subsequent risk of mortality using a patient's preoperative conditions. Serious treatable complications include deep vein thrombosis/ pulmonary embolism, pneumonia, sepsis, and shock/cardiac arrest. These complications, if not identified and treated in time, can cause lengthened hospital stays, morbidity,...
Sepsis is the systemic response to infection complicated by organ dysfunction. It is a leading cause of in-hospital mortality, with an observed mortality of 20–40%, and is associated with significantly high costs. Furthermore, patients who survive sepsis are more likely to have permanent organ damage, cognitive impairment and physical disability. Survival from sepsis is dependent on early and targeted...
