In this project we address the problem of power consumption for wireless sensor nodes. This is where among different components of a sensor, RF transceivers consume a significant amount of power e.g. approximately 80%. Hence the main objective is this project is to tackle the power consumption problem at the RF transmitter, where we aim to reduce the power consumption to micro-watts of power, with minimal sacrifice in achievable data rate and by keeping the connectivity range within an acceptable radius.
Discontinuities of service, variations in voltage magnitude, and distortions in AC voltage waveforms constitute the different aspects poor power quality. A poor quality of power supply can cause malfunction of sensitive equipment and interrupt industrial processes, resulting in significant economic losses. Utilities and consumers are taking actions to maintain the power quality set by the standards. Monitoring of power quality at all levels in the power system is necessary to ensure adherence to standards, but specialized power quality monitoring equipment are expensive.
Surface waters typically have high levels of natural organic matter. The reaction of this organics with chlorine, which is generally used for disinfection, results in the formation of carcinogenic chlorine disinfection by-products (DBPs).
In order to grow into healthy, successful adults, children need environments that support their physical and mental health, engage them in learning, and help them to develop social skills. Out-of-school programs are one kind of support that can help shape childrens futures in a positive way.
Studies have indicated a positive correlation between teaching robotic programming using a virtual platform with speed of learning and deeper level understanding. We will study how students learn when provided with just physical robots, just virtual robotics software, and both in conjunction with each other. This study will also attempt to assess indicators of learning that are more in line with the direction of the Next Generation Science Standards (NGSS), under the assumption that they will be more relevant to modern students, educators, and the corporations in relevant fields.
Modern electric power systems are complicated, large-scale dynamical systems that need specialized tools and techniques for their computer modeling and simulation. This is due to the unprecedented penetration of renewable energy sources and use of high-frequency power electronic converters. This proposal aims to develop algorithms and methods for co-simulation of modern power systems using dynamic phasor and electromagnetic transient (EMT) type simulators.
The Freshwater Oil Spill Remediation Study (FOReST) project will use small contained oil spills in enclosed environments within a lake to study examine the effectiveness of shoreline cleanup procedures and potential ecological impacts of oil spills. The resilience of freshwater aquatic ecosystems to recover from a spill will also be examined. We will examine the ability of bacterial communities to respond to the introduction of oil and biodegrade petroleum compounds.
Many alternate treatment options are now used to alleviate chronic intestinal inflammation and microbial imbalance including dietary supplements of prebiotics and probiotics. Resistant starch (RS) represents a range of indigestible dietary carbohydrates passing into the lower gut, without being digested/absorbed in the upper digestive tract. It is speculated that RS can reduce signs and symptoms of intestinal inflammation through modification of the gut microbial communities, regulation of local inflammatory cytokines, and its effects on mucosal barrier system.
G protein-coupled receptors (GPCRs) are the largest family of membrane proteins and are involved in various disease including hypertension and airway diseases. With >30% of the prescription drugs targeting GPCRs, they have immense therapeutic importance. The detection of antibodies against GPCRs in these diseases has been a challenging task due to the lack of efficient detection assays, which are easy to use and economically available. The company Acudex has a long-term interest in the development of GPCR assays for autoimmune diseases.
We intend to create a novel mixed physical and virtual environment for use in resident education and surgical pre-planning. Our goal is to improve patient safety and amplify training and planning regimes with technology adjunctive to classic apprenticeship or cadaver-based education. To achieve this, we propose the creation of a mixed simulation paradigm expanding on our previous work with printed and virtual simulation where the effective elements of both simulations are combined.
