This dissertation presents the algorithm, methodology, modeling, and system development of a GIS-enabled multi-year pavement rehabilitation needs analysis system which can perform multi-year network-level pavement rehabilitation needs analysis subject to funding availability, minimum performance requirements, and balancing constraints. The system links network-level analysis results directly with project-level maintenance plans and, therefore, can generate not only network-level results but also detailed project-level rehabilitation plans, such as when to treat, where to treat and what treatment method to use. The system first utilizes the current and historical project level pavement condition evaluation information stored in the central Oracle database to forecast future project performance ratings and distresses, to determine appropriate treatment methods and costs, and to calculate life-cycle cost effectiveness ratios for all the projects in the pavement network. Based on this information, a methodology was developed to perform various network-level analyses to determine multi-year funding requirements to meet various prescribed pavement performance requirements and to determine optimum pavement rehabilitation plans subject to funding availability and other requirements, such as balancing funding distribution or future pavement performance among Georgia Department of Transportation (GDOT) Engineering Districts or State Congressional Districts. The system integrates graphical information on GIS maps with information in the central Oracle database and the needs analysis results seamlessly so that engineers can perform interactive map-based multi-year what-if needs analysis directly on the maps using the framework and methodology presented in this dissertation. Several case studies using the actual historical pavement condition evaluation data from the GDOT are presented to illustrate the capabilities of the system. The dissertation concludes with a summary of major conclusions and recommendations for future research. Besides linking network-level analysis results directly with project-level maintenance plans, the following major advantages of the system are also recognized: GIS technology is fully utilized in the system. The system is one of the first pavement needs analysis systems that allows an engineer to perform interactive map-based what-if scenario analyses on multi-year pavement needs analysis. The system allows the rehabilitation plans to balance pavement rehabilitation costs and performances among different political jurisdictions. The system can perform various types of analyses to develop multi-year rehabilitation plans subject to various budget and performance constraints together with the balancing constraints. Although the system was developed for GDOT, with slight modifications, the system can be used by engineers in other transportation agencies to perform the same analyses.

One of spheres of activities of teachers and psychologists is the fulfillment of various psychological researches, with the help of which the characteristics of different persons or people groups are tried to be explained. For the research of the interrelation of the group of people the method of sociometric interrogation, providing a great amount of information (data), is mostly used. The treatment of the information usually requires lots of time, problems in speed and precision also arise. Because of these circumstances the need to use information technologies in the treatment of psychological researches appeared. The aim of the work: to create automatic system for analysis and interpretation of sociometric interrogation data. The detailed description of sociometric interrogation method is presented in the study. The possibility of sociometric interrogation information treatment automation and information analysis principles are investigated, methods of sociograms’ formation are researched. The analysis of existing software was performed, its advantages and disadvantages were singled out. The ways of information (data) representation and reflection were discussed. The ways of protection (deposition) of sociometric interrogation information are analyzed. The means of sociometric interrogation information treatment automation are presented in the work. Lots of attention is devoted not only to creation of algorithms and programs, but also to the evaluation of the... [to full text]

Rapid determination of the concentrations of molecules related to diseases can provide timely information for treatment options. However, most biomarker quantitation methods require costly and complex equipment. On the other hand, point-of-care systems have less complex instrumentation needs than laboratory-based equipment, but often provide less information; for example, biomarker presence or absence instead of concentration. A complete analysis setup addressing key limitations of both laboratory-based and portable systems is highly desirable. I developed microfluidic devices with visual inspection readout of a target’s concentration from microliter volumes of solution flowed into a microchannel. Microchannels are formed within polydimethylsiloxane (PDMS), and the surfaces are coated with receptors. Capillary flow of target solution in the channel crosslinks the top and bottom surfaces, which constricts the channel and stops flow. The flow distance of the target solution in the channel before flow stops indicates the target’s concentration, enabling simple visual inspection readout without complex detection instrumentation. Because of its easy readout and portability, my system has great potential for use in point-of-care diagnostics. I initially demonstrated a proof-of-concept assay using biotin-streptavidin. Solution capillary flow distances scaled linearly with the negative logarithm of streptavidin concentration over a 100,000-fold range. I measured streptavidin concentrations as low as 1 ng/mL using these microsystems, demonstrating low detection limits. I also characterized the mechanism wherein time-dependent channel constriction in the first few millimeters leads to concentration-dependent flow distances. I demonstrated the visual detection and quantification capability of my system to determine an antigen target, thymidine kinase 1 (TK1). I developed surface modification methods for carrying out flow assays and verified receptor attachment on channel surfaces using fluorescence imaging. I obtained a 1 ng/mL TK1 detection limit in flow assays. I also demonstrated nucleic acid quantitation in my flow devices. I detected specific DNA targets in buffer and synthetic urine at 10 pg/mL levels. A dynamic range of 106 was obtained with single-base mismatch specificity. DNA analogues of two miRNA biomarkers were measured near clinically significant levels, showing great promise for future medical application. The promising results demonstrate that this diagnostic tool offers a simple route to analyte quantitation in microliter volumes, with excellent potential for point-of-care application.

This thesis work is mainly focused on the processes involved in manufacturing of aircraft engine components. The processes are especially about welding and welding methods. The basics of welding and the thesis support has been taken from the GKN Aerospace Sweden AB, a global aerospace product supplier.  The basic objective of this thesis work is to improve the usability of an automation system which is developed for evaluating the weldability of a part. A long run maintainability aspect of this automation system has been considered. The thesis work addresses the problems arising during the usage of a computerised automated system such as process transparency, recognisability, details traceability and other maintenance aspects such as maintainability and upgradability of the system in the course of time. The action research methodology has been used to address these problems.  Different approaches have been tried to finding the solution to those problems. A rule based manufacturability analysis system has been attempted to analyse the weldability of a component in terms of different welding technics. The software “Howtomation” has been used to improve the transparency of this analysis system. User recognisability and details tractability have been taken into account during the usage of a ruled based analysis system. The system attributes such as maintainability, upgradability, adaptiveness to modern welding methods has been addressed. The system suitability for large scale analysis has been considered.
