Texto completoIn the vertex detector of the ILC (International Linear Collider), a large number of extra hits will be generated by electrons coming from the beam background. Momenta of these background electrons typically are lower than particles coming from physics events. Our group in IPHC has proposed the concept of a CMOS pixel sensor with on-chip ANNs to tag and remove hits generated by background particles.During my PhD thesis, I focused on the study of a CMOS pixel sensor with on-chip ANNs from the following aspects :1. The implementation of preprocessing modules and an ANN in an FPGA device for the feasibility study ;2. An on-chip algorithm for cluster search which is a part of preprocessing modules has been proposed to integrate into the ASIC design

Texto completoFramstegen inom CMOS-teknologin och tekniken för bump bondning har möjliggjort utveckling av högupplösande bilddetektorer för detektering av enskilda röntgenfotoner eller laddade partiklar. Denna avhandling behandlar design och karakterisering av tre pulsräknande utläsningskretsar med 65536 kvadratiska bildelement med storleken 55 x 55 um2. De tre kretsarna, benämnda Medipix2, Mpix2MXR20 och Timepix, delar samma arkitektur och dimensioner. Medipix2 är en utläsningskrets för avbildning med 256 x 256 identiska bildelement som räknar enskilda fotoner utgående från positiva eller negativa laddningspulser. Förförstärkarens återkoppling kompenserar individuellt för läckströmmen i varje bildelement. Ett energifönster kan definieras med hjälp av två identiska diskriminatorkretsar. Varje händelse som faller inom energifönstret räknas i en 13-bitars pseudo-random räknare. Räknaren, utformad som ett skiftregister, fungerar också som in/utregister för varje bildelement. Kretsen kan läsas ut antingen seriellt eller parallellt. Det elektroniska bruset har uppmätts till ~160 e- rms vid en förstärkning av ~9 mV/ke-. Spridningen i tröskelspänning efter justering är ~120 e- rms vilket ger en minsta detekterbar laddningspuls över hela kretsen på ~1100 e-. Den statiska effektförbrukningen i del analoga delen är ~8 mW per bildelement vid Vdda=2,2 V. Mpix2MXR20 är en uppdaterad version av Medipix2. De huvudsakliga förändringarna är: bättre strålningshärdighet, jämnare tröskelvärden och en 14- bitsräknare med overflow. Periferin innehåller också nya DA-omvandlare med mindre steg, förbättrad linjäritet och mindre temperaturberoende. Timepix är en vidareutveckling av Mpix2MXR20 som medger detektering av ankomsttid, time-over-threshold eller pulsräkning individuellt i varje bildelement. Timepix utnyttjar en extern klocka (Ref_Clk) med frekvenser upp till 100 MHz som distribueras över hela bildmatrisen. Förförstärkaren är förbättrad och en enkel diskriminator med 4 bitars tröskeljustering används för att minimera lägsta detekterbara laddningspuls. Mätningar visar ett elektroniskt brus på ~100 e- rms och förstärkningen 16,5 mV/ke-. Med en tröskelspridning på 35 e- rms blir minsta detekterbara laddning för den nakna kretsen (t.ex. i en gasfylld detektor) ~650 eoch för en bondad detektor ~750 e-. Den statiska effektförbrukningen är ~13,5 mV per bildelement vid Vdda=2,2 V och Ref_Clk= 80 MHz. Den här kretsfamiljen har använts i ett antal olika applikationer. Under dessa studier har ett antal begränsningar konstaterats. Bland dessa märks begränsad energiupplösning och begränsad detektorarea. Framtida utvecklingsprojekt, t.ex. Medipix3, kommer att inriktas på att avhjälpa dessa begränsningar genom att utnyttja den senaste utvecklingen på mikroelektronikområdet.

Texto completoBiological research is changing. First, studies are often based on quantitative experimental approaches. The analysis and the interpretation of the obtained results thus need computer science and statistics. Also, together with studies focused on isolated biological objects, high throughput experimental technologies allow to capture the functioning of biological systems (identification of components as well as the interactions between them). Very large amounts of data are also available in public databases, freely reusable to solve new open questions. Finally, the data in biological research are heterogeneous (digital data, texts, images, biological sequences, etc.) and stored on multiple supports (paper or digital). Thus, "data analysis" has gradually emerged as a key research issue, and in only ten years, the field of "Bioinformatics" has been significantly changed. Having a large amount of data to answer a biological question is often not the main challenge. The real challenge is the ability of researchers to convert the data into information and then into knowledge. In this context, several biological research projects were addressed in this thesis. The first concerns the study of iron homeostasis in the pathogenic yeast Candida glabrata. The second concerns the systematic investigation of post-translational modifications of proteins in the pathogenic yeast Candida albicans. In these two projects, omics data were used: transcriptomics and proteomics. Appropriate bioinformatics and analysis tools were developed, leading to the emergence of new research hypotheses. Particular and constant attention has also been paid to the question of data reproducibility and sharing of results with the scientific community

As the advances of the computer technology, the users have changed their information needs from information of simple types to multimedia information. Image segmentation plays an important role in bridging the gap between human perception and computer vision. Basically, image segmentation is the first step toward applications of computer vision, pattern recognition and video compression. In this thesis we present a new segmentation algorithm for color images based on a series of region growing and merging processes using triangle inequality. This algorithm starts with the region growing process, which groups pixels into homogeneous regions by the shortest-path spanning tree technique. Each resulting small region is then merged to the region which is the nearest to it in terms of color similarity and spatial proximity. One problem with region growing is its inherent dependency on the selection of seed region, which can be avoided by using the shortest-path labeling technique. In the proposed video object segmentation algorithm, we use simple frame differences to identify moving pixels, which are detected according to the segmentation results of consecutive frames. The detected moving pixels are then grouped into a video object plane by employing the so-called isolated noise elimination operator. Based on the video object segmentation algorithm, a hardware architecture, which is described by the hardware description language – Verilog and simulated by the Xilinx Foundation is also proposed. We also pay attention to the design of the parallel computation model by pipeling the data path. Experimental results show that the proposed method is superior to other methods for comparison in terms of computational complexity and the data regularity for hardware architecture design.

When an earthquake occurs close to an urban area, it is easy to cause the collapse of buildings and other damages following by the surface rupture. It also results in unpredictable disasters. In order to estimate the amount of damages following by an earthquake, it is important to understand how an earthquake causes the surface rupture. Furthermore, the surface rupture is closely related to the underground fault geometry and subsurface structure. Thus it is necessary to obtain detail and continuous inter-seismic or co-seismic ground slips to study surface rupture fault and fault geometry. On Sep. 21, 1999, Mw 7.6 Chi-Chi earthquake occurred in Taiwan. It causes many damages at the area of surface rupture. At the Tsaotun area, the surface rupture always occured along the Chelungpu fault (CLPF). In addition, about 2km from the east of CLPF, there was an Ailiao fault (ALF) which also created some surface deformation, thus there should be changes in co-seismic ground displacement. In previous study, a more complete measurement of the co-seismic ground displacement was retrieved from sub-pixel correlation of SPOT satellite images. The displacement distribution was used to study the surface deformation and underground geometry of the CLPF structure. However, it cannot accurately locate the position of surface rupture of CLPF and there were no obvious changes in displacement on ALF due to the low resolution of SPOT images. In this study, the high-resolution aerial photographs are used for analysis. This study also uses orthorectification to eliminate the distortion from the topography and sub-pixel correlation to compare and analyze orthor-images, and then obtain more accurate co-semic surface displacement. The result clearly shows the location of surface rupture of CLPF and the obvious change in horizontal displacement on ALF. By east-west profiles, the changes in horizontal displacement were 4.5~5.5 meters toward west and 3~4 meters toward north cross the CLPF, and the changes of the northern segment was greater than the southern one. The changes in horizontal displacement were only 1~2 meters toward west cross the ALF, the changes zone of the southern segment was shorter than the northern one, and the greatest change was appeared in the middle of the southern segment. Therefore, the dip of northern segment was bigger than the southern one on the CLPF plan at Tsaotun, and closed to the result from level elevation changes. Further, the angle of subsurface plane should be an obvious change in the middle of the southern segment. This study applies sub-pixel correlation to the higher resolution aerial images and provides a more accurate result than the SPOT images can. In addition to the discussion of the relationship between the fault and its underground geometric structure, this method may be able to produce the surface displacement even in the area with smaller earthquakes.
