Early, Jared WBusiness Opportunity Analysis of Wearable and Wireless Electromyography Sensors in Athletics
Master of Sciences, Case Western Reserve University, 2016, Physics
An athlete’s quality of training has impacts on their long-term performance. Suboptimal training then prevents and athlete from achieving their full potential. The scope of the work focuses on the feasibility of a technology based on a wearable and wireless electromyography sensor to detect the onset of muscle fatigue in elite athletes. The work analyzes the biophysics of electromyography, techniques to measure muscle fatigue, and the business opportunities available. The analysis found that successfully measuring fatigue using electromyography sensors provide a difficult challenge and building a business around the technology may cause poor returns on investment. The innovation is better served when championed by a company that has the resources to develop the technology, not a startup.

Al-Khateeb, Shadi A.Fire Detection Using Wireless Sensor Networks
Master of Science in Engineering, Youngstown State University, 2014, Department of Electrical and Computer Engineering
Fire threatens man, animals, plants and properties. So there should be a very adequate, fast, and easy to install alarm systems to avoid the fire consequences. A wireless sensor network (WSN) with multiple wireless sensor nodes and a base station for fire detection is presented. It is a low-cost, easy to construct, highly efficient, fast, and reliable wireless sensor network. Wireless nodes measure the temperature and light intensity in their surrounding areas. The temperature and light data from the wireless nodes are used to detect the fire event and then the system sounds an alarm. The wireless sensor nodes collect and send data continuously to the base station, which is connected to a computer. Software application has been developed in order to conduct the data mining of the wireless sensor network. The WSN has shown the efficiency of mining real time data, reliability, and its flexibility for expansion.

Naik, Ameet MohanPerformance Evaluation Of Hybrid Wireless Sensor Network Simulation At Scale
MS, Kent State University, 2011, College of Arts and Sciences / Department of Computer Science
Networks of wireless sensors are notoriously difficult to experiment with. Testbeds became the experimenter's tool of choice. However, some of potential sensor network applications require the scales that are difficult to achieve on a testbed. Simulation may be a possible substitute. Yet, the radio propagation patterns of low-power radios used by wireless sensors are difficult to model with high fidelity. The errors that the simulation introduces compound at large scale rendering the results suspect. We propose to a combined approach where radio communication between wireless sensor nodes on a testbed is used in real-time to boost the fidelity of large scale simulation. In this thesis we present a series of experiments that demonstrate the viability and evaluate the efficiency of this approach.

Babb, Jeffrey RossBRIDGING THE GAP BETWEEN PUBLIC VISITORS AT LACAWAC SANCTUARY AND LAKE RESEARCHERS: DEVELOPING OUTREACH MATERIALS ON ADVANCED ENVIRONMENTAL SENSORS
Master of Environmental Science, Miami University, 2013, Environmental Sciences
The purpose of this practicum is to help Lacawac Sanctuary visitors better understand ecological monitoring and spark their interest on the data being collected there. Researchers and other guests visiting the sanctuary currently have little information about the monitoring taking place on site. To fill this void, Lacawac visitors have been provided with educational materials, displays, and a program that focuses on ecological monitoring technology and its importance to understanding the ecology of lakes. Specifically, these materials are an educational pamphlet, an interpretive sign, information for Lacawac's website, and a short lesson plan. All of the educational materials highlight a monitoring platform on Lake Lacawac along with the parameters it measures and how the data collected are being used. Now people of all ages and backgrounds visiting Lacawac Sanctuary can enjoy, appreciate, and understand the usefulness of ecological monitoring here and throughout the world.

Vikram, Anil BabuTRACKING IN WIRELESS SENSOR NETWORK USING BLIND SOURCE SEPARATION ALGORITHMS
Master of Science in Electrical Engineering, Cleveland State University, 2009, Fenn College of Engineering
This thesis describes an approach to track multiple targets using wireless sensor networks. In most of previously proposed approaches, tracking algorithms haveaccess to the signal from individual target for tracking by assuming (a) there is only one target in a field, (b) signals from different targets can be differentiated, or (c) interference caused by signals from other targets is negligible because of attenuation. We propose a general tracking approach based on blind source separation, a statistical signal processing technique widely used to recover individual signals from mixtures of signals. By applying blind source separation algorithms to mixture signals collected from sensors, signals from individual targets can be recovered. By correlating individual signals recovered from different sensors, the proposed approach can estimate paths taken by multiple targets. Our approach fully utilizes both temporal information and spatial information available for tracking. We evaluate the proposed approach through extensive experiments. Experiment results show that the proposed approach can track multiple objects both accurately and precisely. We also propose cluster topologies to improve tracking performance in low-density sensor networks. Parameter selection guidelines for the proposed topologies are given in this Thesis. We evaluate proposed cluster topologies with extensive experiments. Our empirical experiments also show that BSS-based tracking algorithm can achieve comparable tracking performance in comparison with algorithms assuming access to individual signals.

BHATIA, AKASHA MODIFIED WIRELESS TOKEN RING PROTOCOL TO PREVENT DATA COLLISON IN WIRELESS TRAFFIC SENSORS
MS, University of Cincinnati, 2006, Engineering : Civil Engineering
Intelligent Transportation Systems, or ITS, is about using technology to solve transportation engineering problems. There is a major push by the Departments of Transportation to use wireless sensors all over the highways to provide accurate traffic information in real-time. Wireless Token Ring Protocol (WTRP), a wireless protocol based loosely on IEEE 802.4 [8] Token Bus Protocol, is an excellent Medium Access Control layer level protocol to prevent data collision in this wireless sensor network on the freeways. The distances between wireless sensors on the freeway were calculated, based on sensor frequency, sensitivity of the receiver and the transmitters, using the Free Space Path Loss Equation. Based on these calculations, it was found that Wireless Token Ring Protocol could fail, as the distances between the sensors was quite large and the data packets got lost, when being transmitted from the last sensor back to the first sensor. The Wireless Token Ring Protocol was modified such that instead of being uni-directional, transmitting data in one direction only; it became bi-directional, transmitting data in both directions. As such, during simulation, it was found that, the performance of the Modified Wireless Token Ring Protocol was better than that of Wireless Token Ring Protocol. The number of data packets that were lost in transmission or corrupted using Modified Wireless Token Ring Protocol was drastically less than that using Wireless Token Ring Protocol, over the same node positions. Hence, the Modified Wireless Token Ring Protocol is more effective than the Wireless Token Ring Protocol to prevent data collision and corruption on the field.
