    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Heavy-duty; Turbine; Axial; Radial; Machine Design; Maskinkonstruktion;

    Sammanfattning : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. LÄS MER

  3. 12. System Design for DSP Applications with the MASIC Methodology

    Författare :Abhijit Kumar Deb; KTH; []
    Nyckelord :System design methodology; Signal processing systems; Design decision; Communication; Computation; Model development; Transaction level model; System design language; Grammar; MASIC.;

    Sammanfattning : The difficulties of system design are persistentlyincreasing due to the integration of more functionality on asystem, time-to-market pressure, productivity gap, andperformance requirements. To address the system designproblems, design methodologies build system models at higherabstraction level. LÄS MER

  4. 13. Food packaging design to support sorting behavior

    Författare :Babak Nemat; Mariano Jr Reyes Ramirez; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Household waste; design attributes; packaging waste; design approaches; sorting behavior; sustainability; Resource Recovery; Resursåtervinning;

    Sammanfattning : Due to population growth, urbanization, higher income levels, and intensive use of packaging products, the amount of waste generated by households, including food packaging waste, has been increasing continuously worldwide, posing a massive threat to societies and the environment. Therefore, proper waste management has become a challenging environmental issue and priority for governments. LÄS MER
