Conducting polymers entered the research field in late 70 ́s and efforts aimed at achieving printed electronics started a decade later. This thesis treats printable organic electrochemical transistors (OECT). Some conjugated polymers can be switched between a high conducting and a low conducting state in an electrochemical cell. In this thesis, the work carried out using poly(3,4ethylenedioxythi...

Mobile augmented reality system is the next generation technology to visualise 3D real world intelligently. The technology is expanding at a fast pace to upgrade the status of a smart phone to an intelligent device. The research problem identified and presented in the current work is to view actual dimensions of various objects that are captured by a smart phone in real time. The methodology pr...

A novel low power CMOS imaging system with smart image capture and adaptive complexity 2D-Discrete Cosine Transform (DCT) is proposed. Compared with the existing imaging systems, it involves the smart image capture and image processing stages cooperating together and is very efficient. The type of each 8 × 8 block is determined during the image capture stage, and then input into the DCT block, ...

In neurological system of primates, changes in posture are detected by the central nervous system through a vestibular process. This process, located in inner ear, coordinates several system outputs to maintain stable balance, visual gaze, and autonomic control in response to changes in posture. Consequently the vestibular data is merged to other sensing data like touch, vision,.... The visuo-i...

A spatial light modulator (SLM) is a device that can impress information on an optical wave front. An electrically addressed SLM translates information from the electronic domain to the optical domain. The applications for SLM's are numerous; they inciude coherent optical processing applications, data routing, data input to optical processing systems, and information display. Spatial light modu...

Understanding human behavior in video is essential in numerous applications including smart surveillance, video annotation/retrieval, and human computer interaction. However, recognizing human interactions is a challenging task due to ambiguity in body articulation, variations in body size and appearance, loose clothing, mutual occlusion, and shadows. In this paper we present a framework for re...

Modern "smart" CMOS sensors have penetrated into various applications, such as surveillance systems, bio-medical applications, digital cameras, cellular phones and many others. Reducing the power of these sensors continuously challenges designers. In this paper, a low power global shutter CMOS image sensor with Wide Dynamic Range (WDR) ability is presented. This sensor features several power re...

CMOS APS technology allows including signal processing in the sensor array. Inclusion of functionality however will come at a cost both financially and in the field of limited applicability. Based on two real world examples (micro digital sunsensor core and lightning flash detector for Meteosat Third Generation (MTG)) it will be demonstrated that large system gains can be obtained by devising s...

Background: Breeding soundness evaluation (BSE) is the primary assessment for determining reproductive potential of male animals. This method, however, cannot be used to evaluate semen frequently or to predict future semen quality. Computerized analysis of ultrasonographic images provides information on histophysiological changes in male reproductive organs.We hypothesized that: 1. semen parame...

background: a major issue in many gene expressionstudies utilizing small amount of biological materials is thelimited quantity of rnapurified from clinical samples, which isoften used for rt-pcr or standard northern blot analysis.objectives: the smart cdna synthesis method and subsequentsmart-cdna-pcr technique was used to analyse 3genes in macroschizonts of theileria annulata in small lymphnod...
