  2. 31. Geometric Computer Vision for Rolling-shutter and Push-broom Sensors

    Author : Erik Ringaby; Per-Erik Forssén; Anders Heyden; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shutter cmos video rectification stabilisation push-broom kinect;

    Abstract : Almost all cell-phones and camcorders sold today are equipped with a CMOS (Complementary Metal Oxide Semiconductor) image sensor and there is also a general trend to incorporate CMOS sensors in other types of cameras. The sensor has many advantages over the more conventional CCD (Charge-Coupled Device) sensor such as lower power consumption, cheaper manufacturing and the potential for on-chip processing.

  4. 32. Wireless, Single Chip, High Temperature Monitoring of Power Semiconductors

    Author : Joakim Nilsson; Johan Sidén; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : Because failures in power electronics can cause production stops and unnecessary damage to interconnected equipment, monitoring schemes that are able to predict such failures provide various economic and safety benefits. The primary motivation for this thesis is that such monitoring schemes can increase the reliability of energy production plants. READ MORE

  5. 33. Photo diodes for machine vision : device characteristics and a-Si:H deposition and analysis

    Author : Annika Rantzer; Marcus Böhm; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : During the last years the area of digital cameras based on CMOS technology has grown rapidly. In CMOS, signal processing circuitry and sensor elements can be combined on the same chip, which has resulted in advanced machine vision chip designs. READ MORE

  6. 34. Power electronics for resistance spot welding equipment

    Author : Jawad Saleem; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Resistance spot welding is an inexpensive and efficient way ofjoining metals. It has extensive applications in household appliancesand in automotive industries. The traditional approach in relation tospot welding machines is to use 50 Hz welding transformers. Thedrawback associated with these transformers is that they are both heavyand bulky. READ MORE

  7. 35. Diagnostic criteria and dose limiting approaches for image modalities in odontology

    Author : Daniel Benchimol; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Objectives: Technical innovations in radiography enable the development of new approaches to reduce the dose to patients. The aim of this thesis was to explore dose optimization approaches for the most frequently used radiographic modalities in dentistry. READ MORE
