Post Earthquake Investigation Field Manual For The State Of Kentucky, Ann G. Sardo, Thomas E. Sardo, Issam E. Harik

Kentucky Transportation Center Research Report

The rapid assessment of a bridge structure’s safety and functionality is an essential component to restoring vital lifeline routes after a major earthquake. Appropriate posting categories are used to assure the safety of the traveling public. The objective of this manual is to provide a rapid and efficient method of inspecting bridge structures after an earthquake. The primary users of this manual are intended to be the initial Kentucky Transportation Cabinet personnel who will initially reach the bridge sites. It is recognized that such first-line personnel will possess a variety of backgrounds and, therefore, a systematic method of evaluating the …

An Analysis Of Indicator Organism Suitability For Lower James And York Rivers, Rhonda Ashonti Ford

Civil & Environmental Engineering Theses & Dissertations

The primary objectives of this thesis are (1) determine if the proper indicator organism is being utilized to determine the bacterial water quality in the State of Virginia. (2) If other environmental factors can predict the bacterial water quality. The current indicator organism of choice for bacterial water quality of waters in the State of Virginia is enterococci, for estuarine and brackish waters. E. coli is the indicator organism of choice for fresh waters in Virginia.

The study concluded (1) Enterococci are the best indicator organism for beaches located in the Hampton Roads Harbor and the Lower James River. (2) …

Anywhere, Anytime, Anysize, Any Signal: Scalable Remote Information Sensing And Communication Systems, George Markowsky

University of Maine Office of Research Administration: Grant Reports

Several recent meetings have highlighted the growing interest in the biological, ecological, environmental, and other research communities in the development and deployment of large distributed systems for information collection, aggregation, analysis, simulation, predictive modeling and realtime analysis within their respective disciplines. Likewise, recent events have caused concern and raised interest in the need for similar systems in the context of homeland security. It seems apparent that a structured discussion of the needs for these systems could create opportunities for synergistic efficiencies between the various user communities. To date, however, no such discussions have been held among these differing user communities, …

Cee3030 - Uncertainty In Engineering Analysis, Spring 2006, Gilberto E. Urroz

Civil and Environmental Engineering - OCW

This course on uncertainty in engineering analysis can also be referred to as probability and statistics for engineers. In particular, we will deal with the applications of probability and statistics to problems related to civil and environmental engineering. Note: Technical Requirements, Maple 10 by Maplesoft

Discrete Cosine Transform Based Shift Estimation For Fringe Pattern Profilometry Using Generalized Analysis Model, Jose F. Chicharo, Jiangtao Xi, Yingsong Hu, Zongkai Yang, Enbang Li

Faculty of Engineering - Papers (Archive)

This paper presents a new analysis algorithm to carry out profile measure- ment with low computational complexity and less noise-sensitivity. Firstly, a discrete cosine transform (DCT) based representation method is introduced to express the height distribution of the three-dimensional surface. Then, a novel shift estimation algorithm, called DCT based shift estimation (DCT-SE) is presented to reconstruct three-dimensional object surfaces by using the proposed expression and the generalized analysis model. The advantage of DCT-SE is that without loss of measurement precise it provides lower computational complexity to implement three-dimensional reconstruction from distorted fringe patterns and at the same time survives from …

General Methodology For Analysis And Modeling Of Trust Relationships In Distributed Computing, Weiliang Zhao, Vijay Varadharajan, George Bryan

Faculty of Engineering - Papers (Archive)

In this paper, we discuss a general methodology for analysis and modeling of trust relationships in distributed computing. We discuss the classification of trust relationships, categorize trust relationships into two layers and provide a hierarchy of trust relationships based on a formal definition of trust relationship. We provide guidelines for the analysis and modeling of trust relationships. We review operations on trust relationships and relative types of trust relationships in our previous work. We provide a set of definitions for the properties of direction and symmetry of trust relationships. In order to analyze and model the scope and diversity of …

Gait Analysis Of Low-Cost Flexible-Shank Transtibial Prostheses, Winson Lee, Ming Zhang, Peggy Chan, David A. Boone

Faculty of Engineering and Information Sciences - Papers: Part A

The latest lower-limb prosthetic designs have been incorporated with dynamic elastic response (DER) components to enhance prosthesis flexibility, which are suggested to be beneficial to gait. Although DER prosthetic. feet are preferred by most transtibial amputees and their benefits to gait are supported by some biomechanical studies, many are still utilizing the simple conventional solid ankle cushioned heel (SACH) designs because of the lower cost. The monolimb, a transtibial prosthesis with the socket and the shank molded from a single piece of thermoplastic material, perhaps is an alternative to DER feet for providing flexibility at the shank. In addition to …

Explicit Dynamic Fem Analysis Of Multipass Vertical-Horizontal Rolling, Hai-Liang Yu, Xiang-Hua Liu, Xian-Ming Zhao, Di Wu, Y Kusaba

Faculty of Engineering and Information Sciences - Papers: Part A

Three passes of plate rolling during vertical-horizontal rolling process are simulated with explicit dynamic finite element method and updating geometric method. The equivalent strain and stress fields, and shape change at the head and tail of slab during rolling are obtained. The calculated result of the shape at the head and tail of slab is in good agreement with the measured one. The explicit dynamic finite element method and updating geometric method can be used effectively to analyze the multipass vertical-horizontal (V-H) rolling process. © 2006 Central Iron and Steel Research Institute.

Assessment Of Spatial Analysis Techniques For Estimating Impervious Cover, Steven Roso, Michael J. Boyd, Laurie A. Chisholm

Faculty of Engineering - Papers (Archive)

Impervious cover proportion is recognised as an important parameter in hydrologic modelling. Recent advances in the spatial sciences provide new capabilities for estimation of this value. This paper describes an assessment of seven estimation techniques, including human and computer based methods requiring a range of different input data and skill levels. In order to quantify the value of any gain in accuracy, the results from each method were applied to a real catchment using event based (WBNM) and continuous simulation (MUSIC) hydrologic models. The results showed that use of high resolution satellite imagery enabled the most accurate measurements of impervious …
