This thesis studies the optimization of diagnosis defects of the photovoltaic cells in the darkroom by the help of new operating software for the used CCD camera. First the present situation and the possible solutions are analyzed. Then the attention is paid to the theory of light-sensitive CCD sensors, their construction, their principles of operation and the theory of scanning images. The thesis also focuses on the analysis of the function of the operating libraries which were provided by the equipment producer. The key part is the development of the application for the camera G2-3200 of the "Moravske pristroje" company which significantly accelerates the work with the camera in the darkroom.

In live we often involve monitoring of very fast actions, that are not observable by the human eye. The thesis focuses on possibilities of high speed digital cameras, their application in industry, and the mechanism of chip formation. The experiment part aims to record the chosen process of chip machining and the problems of necessary illumination during the process of object imaging.

This thesis is focused on possibilities of high-speed digital cameras and their use in different fields of industry. It describes the mechanism of chip forming in orthogonal turning. Subsequently experiments focused on comparison and select the right lens and method of illumination are implemented. These findings are then used in obtaining the record of chip forming by using high-speed digital camera. Key words

This diploma thesis deals with the topic of investigative journalism in a democratic society, on the example of Günter Wallraff, a pioneer of German investigative journalists. His work and methods are controversial and questioned, so I focused on what ethical and legal obstacles his two selected works had to overcome. I chose two reports - Informationen aus dem Hinterland and Ganz unten, from the seventies and eighties of the twentieth century. Both reports were filmed with a hidden camera and were therefore not accepted by the public at first, but after the Federal Constitutional Court's decision, the hidden camera search method was just recognized if it leads to the detection of misstatements. To answer the research questions, I worked with period archival articles and secondary literature. I have connected concrete information from the articles with the knowledge from secondary literature. Reconstructing the link between the two works, the motive of the whole work was journalism as the fourth power in the state, which ensures respect for human rights and freedoms and thus contributes to the maintenance of a democratic society.

Imaging photoplethysmography (iPPG) has attracted much attention over the last years. The vast majority of works focuses on methods to reliably extract the heart rate from videos. Only a few works addressed iPPGs ability to exploit spatio-temporal perfusion pattern to derive further diagnostic statements. This work directs at the spatio-temporal analysis of blood perfusion from videos. We present a novel algorithm that bases on the two-dimensional representation of the blood pulsation (perfusion map). The basic idea behind the proposed algorithm consists of a pairwise estimation of time delays between photoplethysmographic signals of spatially separated regions. The probabilistic approach yields a parameter denoted as perfusion speed. We compare the perfusion speed versus two parameters, which assess the strength of blood pulsation (perfusion strength and signal to noise ratio). Preliminary results using video data with different physiological stimuli (cold pressure test, cold face test) show that all measures are in fluenced by those stimuli (some of them with statistical certainty). The perfusion speed turned out to be more sensitive than the other measures in some cases. However, our results also show that the intraindividual stability and interindividual comparability of all used measures remain critical points. This work proves the general feasibility of employing the perfusion speed as novel iPPG quantity. Future studies will address open points like the handling of ballistocardiographic effects and will try to deepen the understanding of the predominant physiological mechanisms and their relation to the algorithmic performance.

Denna rapport beskriver utvecklingen av en referensdesign för en WiFi-modul från före- taget H&D Wireless. Referensdesignen skulle vara en kamera som kan skicka videodata trådlöst via den nyss nämnda WiFi-modulen. Projektet genomfördes under våren 2015 på företaget som examensarbete för Högskoleingenjörsprogrammet i elektronik och da- torteknik på KTH. Projektet delades upp i tre olika faser: en förstudiefas, en genomförbarhetsfas och en avslutande fas. I förstudiefasen gjordes en litteraturstudie som behandlade vanliga funktioner hos ex- isterande nätverkskameror, videokodningstekniker samt en något djupare studie av olika typer av bildsensorer. Förstudiefasen fortsatte med en analys av olika hårdvarulösningar som skulle kunna användas i projektet. I slutet av fasen valdes den hårdvara som skulle användas i projek- tet. Genomförbarhetsfasen gick ut på att ta reda på om den valda lösningen gick att ge- nomföra. I denna fas skedde huvudsakligen mjukvaruutveckling, under vilken testdriven utveckling tillämpades. En videobuffert samt en HTTP-server för videoströmning togs fram i denna fas. I den avslutande fasen färdigställdes projektrapporten och mjukvaruutvecklingen av- slutades. Mjukvaruutvecklingen för den valda videokodaren sköts upp på grund av att den levererades sent i projektet. I projektet användes en Scruminspirerad projektmetod. Projektmetoden upplevdes fungera bra på grund av metodens flexibilitet och påtvingande av tydliga uppgifter. Vid projektets slut kunde inte den trådlösa kameran färdigställas på grund av problem i kommunikationen med videokodaren. Om videokodaren hade kommit tidigare hade detta problem troligtvis hunnit åtgärdas innan projektets slut, men det är osäkert om implementationen hade hunnit färdigställas ändå på grund av den korta tid som fanns tillgänglig. Trots att projektet inte hann färdigställas helt har det gett många nyttiga lärdomar för framtiden. / company H&D Wireless. The reference design would be a wireless camera that can send video data wirelessly using the aforementioned WiFi-module. The project was carried out at the company during spring 2015 as a thesis project for the Degree Program in Electronics and Computer Engineering at KTH. The project was divided into three stages: a pilot study stage, a feasibility stage and a concluding stage. A literature study was performed during the pilot study stage, which described common functions in existing network cameras, techniques for video encoding and a slightly deeper study of different types of image sensors. The pilot study stage continued with an analysis of different hardware solutions which could be used in the project. The hardware solution which would be used in the project was chosen at the end of the pilot study stage. The purpose of the feasibility stage was to find out whether the chosen hardware solution would be possible to implement. This stage consisted mainly of software de- velopment, during which test driven development was practiced. A video buffer and a HTTP-server for video streaming was developed in this stage of the project. The project report was finished and the software development was wrapped up during the concluding stage. The development of the software for the chosen video encoder was delayed until the concluding stage because of its late delivery. A Scrum inspired project method was used for this project. The project method was perceived to work well in the project because of its flexibility and demand of clear tasks. The wireless camera could was not finished at the end of the project, because of problems in the communication with the video encoder. The problem could probably have been resolved before the end of the project if the video encoder had arrived earlier. It is not sure if the implementation had been possible to complete anyways because of lack of time. Although the project was not completely finished a lot of valuable knowledge was obtained for future work.
