A comparison of Tennessee elected and appointed school superintendents on selected demographic and school system variables
… on selected demographic and school system variables. A questionnaire, consisting of demographic characteristics related to the superintendent and Tennessee school systems, was developed and mailed to all Tennessee superintendents. A total of 137 of 141 superintendents responded, …

Economic efficiency of the collection distribution component of urban mass transit
Recent experiences with urban mass transit systems in North American cities indicate improved efficiency of operation through better co-ordination of mass transit system components. In particular, efficiencies have been improved through innovations in the collection-distribution of transit …

A multi-variate analysis of Indiana school board member attitudes : concerning controversial educational practices and issues
… of school board members and public school systems in Indiana and the educational progressivism of board members as measured by the attitudinal responses of board members to statements on an instrument pertaining to controversial educational practices and issues.A major theoretical …

Simulation program to study MRP nervousness
… Resource Planning (MRP) is a common production system used by many of today's manufacturing facilities. When interactions between a manufacturer and supplier become complex, MRP systems sometimes become chaotic, an event called MRP Nervousness. MRP Nervousness occurs when small scheduling …

A novel framework for predicting patients at risk of readmission
… non-uniform data and lack of knowledge in health system variables. The knowledge of the impact of risk factors will provide clinicians better decision-making and in reducing the number of patients admitted to the hospital. Traditional approaches are not capable to account for the uncertain nature …

Test of a model of job satisfaction for North Carolina school psychologists
… school psychologists have pointed to a number of variables that predict job satisfaction, but research has not yet attempted to test a model of job satisfaction consistent with theory and previous research. The presented study developed and tested a theoretical model of the influences on job …

Statistical Analysis of Electric Energy Markets with Large-Scale Renewable Generation Using Point Estimate Methods
… have introduced serious challenges to power system operation emanating from the uncertainties introduced to the system variables (electricity prices, congestion levels etc.). In order to economically operate the system and efficiently run the energy market, a statistical analysis of the …

Computational Studies of Autocrine Ligand Binding
… of experimental studies of autocrine systems is complicated by both the interdependence of system variables and the difficulty in measuring central parameters including secretion rate and receptor number. A mathematical modeling approach offers hope for improved understanding of the …

Enabling scalable self-management for enterprise-scale systems
Implementing self-management for enterprise systems is difficult. First, the scale and complexity of such systems makes it hard to understand and interpret system behavior or worse, the root causes of certain behaviors. Second, it is not clear how the goals specified at a system-level translate to …

Showup identifications: the effects of presence of stolen property and suspect’s denial on identification performance
A showup identification is the presentation of a single suspect to an eyewitness. I used a simulated theft paradigm and subsequent showup identification to examine the effects of stolen property, suspects’ verbal behaviour, and target-presence on eyewitness identification performance. I used a 2 …

An approximate dynamic programming approach to risk sensitive control of execution costs
… Given an exponential objective function, system variables which are normally distributed, and linear market dynamics, we derive a closed form solution for optimal trading trajectories. We show that a trader lacking private information has trajectories which are static in nature, whilst a …

Estimation of nonlinear systems using Jump Matrix Technique
An estimator for Nonlinear system estimation using Jump Matrix Technique is developed. The idea of the Jump Matrix Technique is to break up the nonlinear system into linear and nonlinear subsystems. The linear subsystem projection, during the sampling interval, is on the basis of the transition …

Design and simulation of a rapid high percision profilometer
A high precision profilometry system was developed for the quality assurance inspection of twosided samples. Based on system specifications and requirements, atomic force microscopy (AFM) was determined to be the most appropriate profilometry technique. The major components of the device include: …

Comprehensive analysis of metabolic pathways through the combined use of multiple isotopic tracers
… that significantly reduces the number of system variables without any loss of information. The elementary metabolite units (EMU) framework is based on a highly efficient decomposition algorithm identifies the minimum amount of information needed to simulate isotopic labeling within a …

A system dynamics model for total-factor productivity measurement of the manufacturing system: its implications for JIT
… (m) and performance of the manufacturing system using a systems approach. Specifically, a conceptual model that captures system-wide performance of the manufacturing system was built using system dynamics in an effort to investigate the relationship between JIT and performance of the …

Assessing Renewable Resource Penetration on Power System Small-Signal Reachability
… proposes a method to assess the impact on power system dynamic performance caused by uncertainty in the system supply side. Operational uncertainty, e.g., demand variability, is not new to power systems. However, with the increased penetration of renewable-based generation, operational …

Optimization of hydraulic networks using the box-complex optimization technique and the linear method of hydraulic analysis
Since the distribution system is often the major investment of a municipal waterworks, it is important that any design satisfy system requirements at a minimum cost. Present design procedures usually employ a trial-and-error process which can be time consuming and lead to non-optimal designs. …
