Demand for selected classes of convenience food in the United States
The focus of this research was the problem of identifying the economic and demographic factors that determine household expenditure for convenience food in the United States. A major objective was to measure, for various classes of convenience food, the response of expenditures to changes in demand …

Monetizing truck freight and the cost of delay for major truck routes in Georgia
… on Interstate-75 (I-75) in Georgia. Truck profiles on Georgia interstates are used to calculate the value of freight by truck type and commodity moved. Determining the types of trucks and commodities moved within the state of Georgia allows the researcher to monetize the effect of recurring …

Global Demand Model to Estimate Supersonic Commercial Services
… commercial supersonic aircraft flights were part of the air transportation system. In the 1970's we had the Russian-built Tupolev Tu-144 and the BAC/Aerospatiale Concorde, the latest being tin operation for 27 years. The work documented in this dissertation focused on the viability of bringing …

An investigation into Indian apparel and textile supply chain networks
The activities of the Indian clothing industry supplying Western markets have been investigated, with particular reference to identifying where improvements could be made to supply chain management. Focus group discussions, case studies and questionnaire analysis established that long lead-times in …

Work Zone Analysis Under Detour Settings
A new approach of work zone delay cost analysis is developed to understand the implications of detours. This method, unlike any of the previous methods, is based on the impacts within the transportation network and let users find the shortest paths which will eventually come to equilibrium. The …

Bus rapid transit : impacts on travel behavior in Bogotá
In the year 2000, the government of Bogotá, the capital of Colombia, undertook a major transformation of its public transport system. A Bus Rapid Transit (BRT) system named Transmilenio was implemented modifying the organizational scheme of service delivery, raising the level of service, and …

Applying Information Visualization Techniques to Visual Debugging
In the arena of software development, implementing a software design (no matter how perfect the design) is rarely done right the first time. Consequently, debugging one's own (or someone else's) software is inevitable, and tools that assist in this often-arduous task become very important with …

Spectral Variability Analysis of BL Lacertae
BL-Lacertae is the prototype of BL Lac objects. It has been observed during the months of May, October and December 2011 with the aim of studying the intranight color variations on short timescales using the method of Color-Magnitude Diagram analysis and to look for the time-lag between the …

Optimizing integrated service for a transit route with heterogeneous demand
… total cost, including user and supplier costs, of a transit route with heterogeneous demand. While minimizing total cost, a set of practical constraints, such as capacity, operable fleet size and frequency conservation, are considered. The research problem is presented in three scenarios, …

Travel behaviors during a public health biological emergency requiring points of dispensing
In the case of a large-scale public health biological emergency, one response task is to distribute medical countermeasures to the general population through Points of Dispensing (PODs). Previous research identified travel decisions as a gap in current operational planning, with little …

ANALYSIS OF SLACK TIME FOR A REAL-TIME RIDESHARE SYSTEM
… As a safety factor can increase the reliability of transit systems, a slack time can be added to the passenger pickup schedule to increase the system stability and reliability. This thesis focuses on a driver-passenger system, modeling three objective cost functions using similar steps and …

Signal timing optimization based on minimizing vehicle and pedestrian delay by genetic algorithm
… selection (two-way or scramble) and the length of WALK phase when scramble crossing is used. An optimization procedure for signal plans in an isolated intersection is developed. The procedure yields up to four phases for vehicles with either the two-way or scramble pedestrian crossing phase. A …

Insight to Mexican E-Commerce and its interaction with future industrial real estate demand
This study conducted some interviews to professionals related to the Retail Logistics Industry, and gained understanding for Mexican E-commerce. After interviewing these professionals, six reasons for the delay of Mexican E-retail were identified. The reasons are: Lack of Confidence from the User, …

Modifying TRANSIMS (Transportation Analysis and Simulation) to Include Dynamic Value Pricing and Departure Time Choice
Value pricing is now an accepted strategy for congestion and demand management in metropolitan areas. Along with alternate congestion management strategies, many transportation agencies have started looking at value pricing as a method to help financial shortfalls of new congestion management …

Using Laboratory Experiments to Better Understand Voluntary Contributions
… which help others (e.g., charities); many of the theoretical models have at their core, that an individual is indifferent between giving time or money. We test this assumption in a laboratory (and other related phenomena concerning giving time and money to charity). Further, we test how …

Automated Detection of Incomplete Exhalation as an Indirect Detection of Auto-PEEP on Mechanically Ventilated Adults
… end-expiratory pressure due to excessive amounts of alveolar gas produced by sustained recurrent incomplete exhalation. Incomplete exhalation occurs when the exhaled breath never reaches a flow rate of 0 L/min. The objective of this dissertation is to develop an automated detection system of …

Mathematical analysis of fractional-order chemostat model with time delay
… is studied to describe the dynamic behaviour of a chemostat system. This study also investigated the FDEs with time delay to examine the effect of time delay on the behaviour of a chemostat system. The integer-order chemostat model in the form of the ordinary differential equation (ODEs) is …

Design and Evaluation of Urban Congestion Pricing Policies with Microsimulation of Passenger and Freight
… congestion has been growing. The contribution of urban freight to congestion has also been increasing due to surging e-commerce demand. Congestion pricing is effective for urban congestion mitigation, yet knowledge about its impacts on the freight sector is insufficient. We propose to design …
