Distributed Spatiotemporal Detection For Chemical And Biological Threats Using Human Immune Mechanisms, Yatin Bodas

Masters Theses

"Ubiquitous detection of chemical and biological (CB) threats in an urban environment using widely distributed, low-cost, broad-spectrum sensors carried by public or on vehicles is extremely desirable and pertinent for homeland security. These distributed sensors should interoperate autonomously and adaptively to meet stringent operational and detection performance requirements. This research explores the use of scalable detection methodology, inspired by the human immune mechanisms to meet these challenges. An adaptive spatiotemporal control mechanism is proposed to organize the detection behavior of spatially dispersed sensors using peer-to-peer communication so that a shorter response time, higher probability of detection and lower false alarm …

Symbol Synchronization And Dynamic Channel Estimation In Multiple Input Multiple Output Systems Using Statistical Analysis Of Eye Diagrams, Abhishek Gupte

Masters Theses

"The research work presented in this document is the continuation of the project to develop a Multiple Input Multiple Output (MIMO) system using band-limited signals in strong multipath environments. The modulation format used is Gaussian Frequency Shift Keying (GFSK). Band-limiting introduces controlled Inter-Symbol Interference (ISI), which along with a multipath environment degrades the features of the received signal waveform that are vital to the performance of standard symbol synchronization techniques. A low complexity algorithm was deemed necessary to counter this problem so that the benefits of conserving bandwidth would not be obviated by an expensive and elaborate receiver architecture.

Such …

Etherannotate: A Transparent Malware Analysis Tool For Integrating Dynamic And Static Examination, Joshua Michael Eads

Masters Theses

"Software security researchers commonly reverse engineer and analyze current malicious software (malware) to determine what the latest techniques malicious attackers are utilizing and how to protect computer systems from attack. The most common analysis methods involve examining how the program behaves during execution and interpreting its machine-level instructions. However, modern malicious applications use advanced anti-debugger, anti-virtualization, and code packing techniques to obfuscate the malware's true activities and divert security analysts. Malware analysts currently do not have a simple method for tracing malicious code activity at the instruction-level in a highly undetectable environment. There also lacks a simple method for combining …

CAD based animations of assembly operations can overcome these shortcomings while offering greater potential for operations analysis and simulation flexibility. However, creating such CAD based training simulations manually is a time intensive task and many a times fail to reveal the practical assembly issues faced in the real world. Thus, it is highly beneficial to be able to automate these simulations using motion capture from a physical environment. This thesis research …

Development Of Novel Backscatter Communication Systems Using A Multi-Hop Framework And Distributed Beamforming, Vikram Reddy Surendra

Masters Theses

"The goal of this thesis it to develop a wireless networking framework for battery-free devices based on passive, backscatter communication. In contrast to traditional, active communication systems, where the radio signal has to be generated using large amount of energy from batteries, the passive systems reflect the RF signal. The information is encoded by modulating the reflected signal, which consumes significantly less energy than active transmission. The existing passive, backscatter systems have limited communication capabilities. For example, the Radio Frequency Identification (RFID) systems support short-distance, direct communication between active reader and passive tags. The communication range is limited due to …
