Structure And Dynamics Of Heterogeneous Molecular Systems, Alfred B. Roney
Structure And Dynamics Of Heterogeneous Molecular Systems, Alfred B. Roney
USF Tampa Graduate Theses and Dissertations
Although current classical force fields describe homogeneous single-componentsystems fairly well, they do not represent the response of an individual molecule's electronic structure to its local environment with enough detail to reliably predict atomic motions in interfacial regions such as a solvation structure or liquid surface.Since most chemical processes of non-trivial interest involve two or more dissimilar molecules interacting at a short distance, molecular models must accurately simulate the interactions between different molecular species as well as bulk behavior in order to provide useful information. Results from two simulation studies are presented to illustrate both the utility of current point-charge electrostatics …
Development Of A Gis Based Infrastructure Replacement Prioritization System; A Case Study, Brian D. Pickard
Development Of A Gis Based Infrastructure Replacement Prioritization System; A Case Study, Brian D. Pickard
USF Tampa Graduate Theses and Dissertations
Maintenance, repair, and replacement of transmission mains and distribution system piping is expected to cost approximately $75 billion over the next two decades to ensure that public water systems are capable of providing the United States with safe drinking water. However, there is a significant gap between the funds available and the projected costs of infrastructure replacement or rehabilitation. Infrastructure Management Systems (IMS) have been developed to assist utilities and decision-makers in determining how to allocate resources for infrastructure. This project utilizes theTampa Water Department (TWD) as a case study to develop a tool for prioritizing infrastructure replacement.
TWD is …
Effects Of Trait Anxiety And Cognitive Appraisals On Emotional Reactions To Psychological And Physical Stressors, Qutayba Abdullatif
Effects Of Trait Anxiety And Cognitive Appraisals On Emotional Reactions To Psychological And Physical Stressors, Qutayba Abdullatif
USF Tampa Graduate Theses and Dissertations
This study investigated the effects of individual differences in trait anxiety on cognitive appraisals and emotional reactions to stressful situations. Specifically, the effects of trait anxiety on the evaluation of psychological and physical threats to well-being were examined in relation to state-anxiety. To accomplish this goal, a proposed model consisting of elements from the Lazarus and Folkman Stress and Coping Model (1984) and Spielberger's State Trait distinctions is presented. To our knowledge, this is the first proposed model to attempt to combine trait anxiety, primary and secondary appraisals, and state anxiety and to utilize path analytic models in assessing empirical …
