  1. 21. Haptics with Applications to Cranio-Maxillofacial Surgery Planning

    Författare :Pontus Olsson; Ingrid B. Carlbom; Blake Hannaford; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; medical image processing; haptics; haptic rendering; haptic gripper; visuo-haptic co-location; vibrotactile feedback; surgery simulation; virtual surgery planning; cranio-maxillofacial surgery; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Virtual surgery planning systems have demonstrated great potential to help surgeons achieve a better functional and aesthetic outcome for the patient, and at the same time reduce time in the operating room resulting in considerable cost savings. However, the two-dimensional tools employed in these systems today, such as a mouse and a conventional graphical display, are difficult to use for interaction with three-dimensional anatomical images.

  4. 23. Towards improving performance and user-friendliness of optical motion capture systems

    Författare :Zlatko Franjcic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Visualization; Photogrammetry; Human-computer interaction; Motion capture;

    Sammanfattning : Measuring the motion of humans, animals or objects is important in various current and future applications. Today, many alternative motion capture systems exist to obtain such measurements. The technological approach to detect motion is often used to classify the systems. LÄS MER

  5. 24. Nonlinear pulse propagation and saturation gain grating phenomena in optical fiber devices

    Författare :Evgeny V. Vanin; KTH; []
    Nyckelord :;

    Sammanfattning : Nonlinear effects are known to influence the propagation ofoptical waves in fibers already at modest power levels. Thisprovides us with a unique tool to observe nonlinear phenomenaunder comparatively simple experimental conditions and alsoopens the door to numerous important applications. LÄS MER

  7. 25. Design and Characterization of SiN-based integrated optical components for Wavelength Division Multiplexing

    Författare :Alexander Caut; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosstalk; silicon nitride.; Mach-Zehnder interferometers; polarization; grating couplers; insertion loss; power splitters; arrayed waveguide gratings; silicon photonics;

    Sammanfattning : To follow the trend of the data traffic and to limit the size of the hyperscale data centers, communication solutions offering small footprint, low cost and low power consumption are needed. Optical interconnects used in data centers are mostly short reach (approximately 100 m) based on GaAs-based 850 nm vertical-cavity surface emitting lasers (VCSELs) and OM4 multimode fibers (MMF).
