Modeling And Optimization Of The Indiana Land Merge Control System On Approaches To Freeway Work Zones, Part I: Implementation Report; Part Ii: Manual Of The Indiana Lane Merge Control System (2 Volumes), Andrzej P. Tarko, Sreenivasulu R. Kanipakapatnam, Jason S. Wasson

JTRP Technical Reports

Severe traffic turbulence on entry sections of freeway work zones increases the delays and risk of crash. A new Indiana Department of Transportation system called Indiana Merge Lane System (IMLS) creates a dynamic no passing zone on the approach to the freeway work zone through the sequence of DO NOT PASS signs. The system is thought to encourage drivers to switch lanes well upstream of the discontinuous lane taper where the merging maneuver is safer and less intrusive. The IMLS is expected to impact drivers’ behavior, their perception of the traffic conditions, and traffic safety. This research is focused on: …

These systems have increasingly been based upon the international series of standards, ISO 9000.In the food industry, safety is a minimum requirement for food quality. As Governments and food authorities have endeavoured to reduce the incidence of foodborne illnesses, they have promoted the implementation of additional systems developed to a specific standard for food safety, namely Hazard Analysis Critical Control Point (HACCP). …

Automatic Flowchart Displays For Software Visualisation, Paul R. Schurmann

Theses: Doctorates and Masters

Understanding large software projects and maintaining them can be a time consuming process. For instance, when changes are made to source code, corresponding changes have to be made to any related documentation. One large section of the documentation process is the creation and management of diagrams. Currently there are very few automated diagramming systems that can produce diagrams from source code, and the majority of these diagramming systems require a significant amount of time to generate diagrams. This research aims at investigating the process of creating flowchart diagrams from source code and how this process can be fully automated. Automating …

A Comparison Of Advanced Time Series Models For Environmental Dependent Stock Recruitment Of The Western Rock Lobster, Saarah A. Farag

Theses: Doctorates and Masters

Time series models have been applied in many areas including economics, stuck recruitment and the environment. Most environmental time series involve highly correlated dependent variables, which makes it difficult to apply conventional regression analysis, Traditionally, regression analysis has been applied to the environmental dependent stock and recruitment relationships for crustacean species in Western Australian fisheries. Alternative models, such as transfer function models and state space models have the potential to provide unproved forecasts for these types of data sets. This dissertation will explore the application of regression models, transfer function models, and state space models to modelling the puerulus stage …

The Experience Of Flow And Learning By Designing Interactive Multimedia Software, Leonie Ramondt

Theses: Doctorates and Masters

As computer technology is increasingly adopted in education, some students continue to have little context for its use. This is particularly true of tertiary drama education students, of whom many still remain computer illiterate. Constructivist pedagogy proposes that a learner constructs knowledge through active participation in their learning. An approach that is gaining currency which applies this principle is learning by designing. This approach was adopted for this study, with the premise that the process of designing multimedia software for their peers would not only motivate these students to use computers but could also lead to a deepening of their …

Signal Processing Topics In Multicarrier Modulation : Frequency Offset Correction For Ofdm And Multiuser Interference Cancellation For Mc-Cdma, Pingping Zong

Theses

Orthogonal frequency division multiplexing (OFDM) is discussed as a special form of multi-carrier modulation (MCM). One major problem of the OFDM system is the sensitivity to an unknown frequency offset at the receiver. To improve the performance of the OFDM system, correction of the frequency offset is required before decision making. An adaptive method of frequency offset correction is presented. The adaptation algorithm used here is based on the LMS and the estimation is proven unbiased. A multiuser communications system having similar signal structure to the OFDM system, termed as multi-carrier code division multiple access (MC-CDMA), is discussed. The MC-CDMA …
