A Reconfigurable Supercomputing Library For Accelerated Parallel Lagged-Fibonacci Pseudorandom Number Generation, Yu Bi
Masters Theses
To help promote more widespread adoption of hardware acceleration in parallel scientific computing, we present portable, flexible design components for pseudorandom number generation. Due to the success of the Scalable Parallel Random Number Generators (SPRNG) software library in stochastic computations (e.g., Monte Carlo simulations), we developed an efficient and portable hardware architecture fully compatible with SPRNG’s Parallel Additive Lagged Fibonacci Generator (PALFG). Our general design produces identical results for all the parameter sets that SPRNG supports and yields high performance parallel random number generators which can each generate 162 million 31-bit uniform random integers per second on Xilinx Virtex II …
Computer Model To Select Leed Certification For Building Projects, Ruba Mirghani Mohammed
Computer Model To Select Leed Certification For Building Projects, Ruba Mirghani Mohammed
Masters Theses
According to the US Green Building Council (USGBC) residential and commercial buildings in the United State consume huge amounts of natural resources; pollute the environment, and generate large amounts of waste, all of which affect the environment, economy, public health, and productivity. As a result, USGBC committees developed the Leadership in Energy and Environmental Design (LEED) rating system to help professionals improve the quality of buildings and lessen their impact on the environment.
The (LEED) Green Building Rating System is a point-based system for certifying the level of a building's sustainability. There are four LEED certification categories: (1) Certified, (2) …
Distributed Self-Deployment In Visual Sensor Networks, Christopher Allan Beall
Distributed Self-Deployment In Visual Sensor Networks, Christopher Allan Beall
Masters Theses
Autonomous decision making in a variety of wireless sensor networks, and also in visual sensor networks (VSNs), specifically, has become a highly researched field in recent years. There is a wide array of applications ranging from military operations to civilian environmental monitoring. To make VSNs highly useful in any type of setting, a number of fundamental problems must be solved, such as sensor node localization, self-deployment, target recognition, etc. This presents a plethora of challenges, as low cost, low energy consumption, and excellent scalability are desired.
This thesis describes the design and implementation of a distributed self-deployment method in wireless …
Automatic Image Based Time Varying 3d Feature Extraction And Tracking, Lu Zhang
Automatic Image Based Time Varying 3d Feature Extraction And Tracking, Lu Zhang
Masters Theses
3D time-varying data sets are complex. The intrinsics of those data cannot be readily comprehended by users solely based on visual investigation. Computational tools such as feature extraction and tracking are often necessary. Until now, most existing algorithms in this domain work effectively in the object space, relying on prior knowledge of the data. How to find a more flexible and efficient method which can perform automatically to implement extraction and tracking remains an attractive topic.
This thesis presents a new image-based method that extracts and tracks the 3D time- varying volume data sets. The innovation of the proposed approach …
The Flood Frog: An Autonomous Wireless Device For Flood Detection And Monitoring, Valerio Plessi
The Flood Frog: An Autonomous Wireless Device For Flood Detection And Monitoring, Valerio Plessi
Masters Theses
"Accurate real time monitoring is gaining critical importance in a broad range of domains. Of particular interest to this research is the development of monitoring and detection systems for environmental and structural phenomena. Transportation infrastructures, in particular bridges, provide examples for both categories. Flooding of low water bridges is one example of rapidly evolving environmental phenomena, while stress and vibration are structural phenomena in need of monitoring.
Early warning and advanced preparation for emergency are two of the most effective lines of defense against catastrophic events, where real time monitoring can facilitate containment and recovery efforts. The operating environment of …
