1	Optimization of Proximity Judgment Day, Brian 01 January 2011 (has links) As humans, we have evolved to see in three dimensions. Our ancestors developed two eyes that only look forward, which allows the visual area that can perceive depth to be most of the field of view. A variety of sensors have been developed which can determine depth in the environment. They range from producing individual points of depth to the depth of everything in the environment. These sensors have become cheap and can now reliably produce accurate depth. Research is needed to determine how to present the proximity information to the people using the sensors. Touch, sound, and vision have all been used to provide depth information to the users. This research focuses on vision and compares methods of visually presenting proximity information to a user. The methods examined are stereovision and false color visual proximity mapping. False color mapping proved most effective while, surprisingly, stereovision was not helpful.

The main function of the program is to convert the monochrome image into the pseudo colors. This procedure is achieved increasing the diagnostic yield of image. The program may find application in medical field. The pseudocoloring is used several different methods for obtaining the best results, combined with modifications increasing brightness scale image contrast images. The program is created in the programming environment of Visual Studio 2008 and written in C # programming language. Entry program is monochrome images in various formats (JPEG, BMP). The output of the program can be printed in a false-color image or stored image again in several different formats.
3	The modernization of a DOS-basedtime critical solar cell LBICmeasurement system. Hjern, Gunnar January 2019 (has links) LBIC is a technique for scanning the local quantum efficiency of solar cells. This kind of measurements needs a highly specialized, and time critical controlling software. In 1996 the client, professor Markus Rinio, constructed an LBIC system, and wrote the controlling software as a Turbo-Pascal 7.0 application, running under the MS-DOS 6.22 operating system. By now (2018) both the software and several hardware components are in dire need to be modernized. This thesis thoroughly describes several important aspects of this work, and the considerations needed for a successful result. This includes both very foundational choices about the software architecture, the choice of suitable operating system, the threading model, and the adaptation to new hardware with vastly different behavior. The project also included a new hardware module for position reports and instrument triggering, as well as several adaptations to transform the DOS-based LBIC software into a pleasant modern GUI application.
