  1. 1. Cost Optimization of Aircraft Structures

    Författare :Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

    Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER

  2. 2. Cost/Weight Optimization of Aircraft Structures

    Författare :Markus Kaufmann; Dan Zenkert; Frédéric Lani; KTH; []
    Nyckelord :Cost Weight Optimization; Weight Penalty; Direct Operating Cost; Composite Structures; Non-destructive testing; Finite element analysis FEA ; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Composite structures can lower the weight of an airliner significantly. The increased production cost, however, requires the application of cost-effective design strategies. Hence, a comparative value is required which is used for the evaluation of a design solution in terms of cost and weight. LÄS MER

  3. 3. Energy Efficient Machine-Type Communications over Cellular Networks : A Battery Lifetime-Aware Cellular Network Design Framework

    Författare :Amin Azari; Guowang Miao; Jens Zander; Cedomir Stefanovic; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine-type communications; Internet-of-things; 5G; Battery lifetime; Energy efficiency; maskin-typ kommunikation; Sakernas Internet; 5G; Energieffektivitet; Batteriets livslängd; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Internet of Things (IoT) refers to the interconnection of uniquely identifiable smart devices which enables them to participate more actively in everyday life. Among large-scale applications, machine-type communications (MTC) supported by cellular networks will be one of the most important enablers for the success of IoT. LÄS MER

  4. 4. The value of social investments : A health economic approach to evaluating parenting interventions

    Författare :Camilla Nystrand; Inna Feldman; Filipa Sampaio; Anna Sarkadi; Eva-Maria Bonin; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; health economics; cost-effectiveness; cost-benefit; public health; child health; mental health; parenting; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Child mental health problems are current welfare challenges and may be costly to the individual, the family and society at large. The problems may persist and result in adverse outcomes later in life, which also carries a large financial burden. LÄS MER

  5. 5. Performance Measures of Road Infrastructures

    Författare :Babak Ebrahimi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCCA; LCA; road infrastructure; SLR; survival analysis; modelling; lifetime; GIS;

    Sammanfattning : Roads are transport infrastructures that play a fundamental role in the development of societies and businesses. They are valuable assets, as they connect places, provide mobility, create jobs and stimulate economic prosperity. LÄS MER
