    Abstract : Within the manufacturing of metallic components, machining plays an important role and is of vital significance to ensure process reliability. From a cutting tool design perspective, physics-based numerical modeling that can predict chip morphology is highly necessary to design tool macro geometry. READ MORE

  4. 2. On the Effect of Grain Size and Hardness on the Machinability of Superalloys and Chip Deformation

    Author : Stefan Olovsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superalloys; Microstructure; Burr; Machinability; Waspaloy; Chip microstructure; Tool wear; Alloy 718;

    Abstract : Superalloys are used in applications such as gas turbines, steam power plants and nuclear power systems that require good high temperature properties and/or exceptional corrosion resistance. Superalloys are classified as materials that are “difficult to machine”. In production machining is a most commonly occurring procedure. READ MORE

  5. 3. Design Issues in VLSI Implementation of Image Processing Hardware Accelerators - Methodology and Implementation

    Author : Hongtu Jiang; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Bildbehandling; image processing; Imaging; Teknik; Technological sciences; Controller Synthesis; Circuit design; FPGA; Image convolution; Image processing; Video segmentation; Signalbehandling; Electronics; Elektronik;

    Abstract : With the increasing capacity in today's hardware system design enabled by technology scaling, image processing algorithms with substantially more complexity can be implemented in a single chip with real-time performance. Combined with the demand for low power consumption or larger resolution seen in many applications such as mobile devices and HDTV, new design methodologies and hardware architectures are constantly called for to bridge the gap between designers productivity and what the technology could offer.
