A Model for Multidisciplinary Optimization for Containerships
(Virginia Tech, 1999-06-15)
This thesis describes a multidisciplinary design optimization approach to containership design. The method employs widely accepted regression equations for computing resistance, weights, building costs and operating costs. ...
Tensile and Flexure Strength of Unidirectional Fiber-Reinforced Composites: Direct Numerical Simulations and Analytic Models
(Virginia Tech, 1998-02-20)
A Local Load Sharing (LLS) model recently developed by Curtin
and co-workers for the numerical simulation of tensile
stress-strain behavior in fiber-reinforced composites is used
to predict the tensile strength of metal ...
Productivity, Cost, and Technical Efficiency Evaluation of Southeastern U.S. Logging Contractors
(Virginia Tech, 1998-05-19)
A group of 35 loggers located across the southeastern United States provided 192 logger years of productivity and cost information. Information, including logger demographics, business, and operational data, was also ...
Fiscal Decentralization and Municipal Budget Policy in Countries with Economies in Transition: Comparing Local Revenue Systems
(Virginia Tech, 1999-05-12)
The thesis explores the effect of fiscal decentralization on local governments budgeting and fiscal autonomy in selected transition countries of Central and Eastern Europe. The implications of legislative changes on local ...
Design of User-Weight-based Exercise Machines
(Virginia Tech, 1997-02-07)
This thesis describes the process of designing exercise machines that raise the weight of the user as the primary source of resistance.
Most strength training machines use weight stacks or springs as the source of ...
Developing an Automated Explosives Detection Prototype Based on the AS&E 101ZZ System
(Virginia Tech, 1997-09-22)
This thesis describes the development of a multi-sensor, multi-energy x-ray
prototype for automated explosives detection. The system is based on the American
Science and Engineering model 101ZZ x-ray system. The 101ZZ unit ...
Exploring Parental Actions to Finance Higher Education
(Virginia Tech, 1998-03-25)
The purpose of this study was to examine parental actions to finance higher education. Data were analyzed from the 1995-96 National Postsecondary Student Aid Study (NPSAS: 96).
Results of this study indicated that gender, ...
Evaluation of Moisture Diffusion Theories in Porous Materials
(Virginia Tech, 1998-08-07)
Moisture transport in building materials is directly responsible for structural
damage, as well as poor indoor air quality. For these reasons, the need to
understand transfer mechanisms and predict moisture transport ...
Kant's Doctrine of Schemata
(Virginia Tech, 1999-05-13)
The following is a study of what may be the most puzzling and yet, at the same time, most significant aspect of Kant's system: his theory of schemata. I will argue that Kant's commentators have failed to make sense of ...
Preparation of highly reflective films by supercritical infusion of a silver additive into poly(ether ether ketone)
(Virginia Tech, 1997-10-03)
There has been a great interest in preparing polymeric reflective surfaces in the last few years. The application of supercritical fluid technology in this area is beginning to receive a great deal of attention. Poly ether ...
