  1. 1. Structural Interaction between Vehicles. An Investigation of Crash Compatibility between Cars and Heavy Goods Vehicles

    Författare :Aleksandra Krusper; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Front Underrun Protection; simulation; Heavy Goods Vehicles; compatibility assessment; FUPD; Front Underrun Protective Device; energy absorption; crash compatibility; HGV; structural interaction; FUP;

    Sammanfattning : While frontal collisions between Heavy Goods Vehicles (HGVs) and passenger cars are rarecompared to car-to-car frontal crashes, they are much more severe. Between 43% and 73% ofall frontal car-to-truck accidents result in fatalities. LÄS MER

  3. 2. Fabrication, Characterisation and Modelling of Subharmonic Graphene FET Mixers

    Författare :Omid Habibpour; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gate dielectric; Graphene; harmonic balance analysis.; subharmonic resistive mixers; microwave FETs; device modelling;

    Sammanfattning : Graphene has exceptional carrier transport properties which makes it a promising material for future nanoelectronics. The high carrier mobility along with the ability to switch between n- and p-channel in a graphene field effect transistor (G-FET) truly distinguishes it from other types of FET technologies and enables completely new high frequency devices.

  4. 3. Car-to-Car Side Impacts: Occupant Injuries, Test Methods, and the Development and Evaluation of Protective Systems

    Författare :Yngve Håland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The present work addresses the problem of injuries following car-to-car side collisions. The injuries in this type of impact have been evaluated to form the basis for the development of test methods and for the principles of protective systems. Side impacts give rise to relatively more severe injuries than frontal impacts. LÄS MER

  5. 4. Integration of Two-Dimensional Materials for Electronics and Photonics

    Författare :Arne Quellmalz; Kristinn Gylfason; Frank Niklaus; Cedric Huyghebaert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Two-dimensional (2D) materials with a thickness on the atomic scale promise to continue the trend of increasing performance in electronics, photonics, and sensing. However, despite record-breaking demonstrations of individual devices, the commercial exploitation of 2D materials is still limited. LÄS MER

  7. 5. Influence of The Education and Training of Prehospital Medical Crews on Measures of Performance and Patient Outcomes

    Författare :Hans Blomberg; Rolf Gedeborg; Jakob Johansson; Karl Michaelsson; Eldar Søreide; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ambulance; prehospital; education; CPR; stroke; trauma; outcome;

    Sammanfattning : Prehospital care has developed dramatically the last decades with the implementation of new devices and educational concepts. Clinical decisions and treatments have moved out from the hospitals to the prehospital setting. In Sweden this has been accompanied by an increase in the level of competence, i.e. LÄS MER
