   Sammanfattning : The transition from conventional cast concrete to 3D Concrete Printing (3DCP) marks a paradigm shift by directly depositing fresh concrete layer upon layer according to a digital model without the need for a formwork. This technology offers the possibility of achieving innovative and complex geometries in an automated process. LÄS MER

3. 2. Performance Analysis and Design Space Exploration of On-Chip Interconnection Networks

   Författare :Abbas Eslami Kiasari; Axel Jantsch; Joerg Henkel; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The advance of semiconductor technology, which has led to more than one billion transistors on a single chip, has enabled designers to integrate dozens of IP (intellectual property) blocks together with large amounts of embedded memory. These advances, along with the fact that traditional communication architectures do not scale well have led to significant changes in the architecture and design of integrated circuits. LÄS MER

4. 3. Design of flexible lattice structures : a design for additive manufacturing perspective

   Författare :Satabdee Dash; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design for additive manufacturing; DfAM; Lattice structures; Flexibility; Compuational methods; Numerical modelling; Engineering design process;

   Sammanfattning : Recent years has seen an unprecedented growth in emerging technologies like Additive manufacturing (AM), augmenting the manufacturing capabilities through a multitude of opportunities while also introducing unique constraints, such as support structures, and post-processing requirements. Taking full advantage of the potential of AM demands product designs to be optimised for both opportunities and constraints specific to AM, requiring evolution from the traditional design for manufacturing to design for additive manufacturing (DfAM).

   Sammanfattning : The use of lightweight parts by the vehicle industry produces immediate benefits on the reduction of emissions because less energy is consumed during the production, service, and recycle stages of a product life cycle. Therefore, the development of processes that allow high design freedom for topology optimisation and materials with high specific strength is a great need. LÄS MER

7. 5. Antiporter-like protein subunits of respiratory chain complex I

   Författare :Kamil Gorecki; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Complex I is the mitochondrial enzyme complex that oxidizes NADH produced in the citric acid cycle and reduces quinone in the membrane, coupled to proton pumping out of the mitochondrial matrix, creating a membrane potential. This process generates about 40% of the energy used by living organisms. LÄS MER
