  1. 16. Selection and use of engineering design methods using creative problems solving principles

    Författare :Belinda López-Mesa; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : Many modern products require the careful planning of a vast number of aspects of their life cycle to succeed in the market, such as, financing, functionality, quality, reliability, environmental impact, manufacturing process, relationship with suppliers, etc. Potentially, the numerous domain- independent design methods generated for decades in the fields of engineering design and creative problem solving (CPS) have much to offer in today's complex multi-objective product design activity.

  3. 17. Securing Information Assets : Understanding, Measuring and Protecting against Social Engineering Attacks

    Författare :Marcus Nohlberg; Benkt Wangler; Stewart Kowalski; Angela Sasse; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap; Teknik;

    Sammanfattning : Social engineering denotes, within the realm of security, a type of attack against the human element during which the assailant induces the victim to release information or perform actions they should not. Our research on social engineering is divided into three areas: understanding, measuring and protecting. LÄS MER

  4. 18. Towards enhanced mechanical braking systems for trains. Thermomechanical capacity of wheel treads at stop braking

    Författare :Mandeep Singh Walia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; full-scale brake rig testing; tread braking; rolling contact fatigue; high temperature fatigue; Railway wheels; stop braking;

    Sammanfattning : Modern trains are equipped with different braking systems, between which the braking effort can be distributed. Among these, tread braking is still the most common system for friction braking. Tread brake systems are cheap and robust. LÄS MER

  5. 19. Passive acoustic leak detection in energy conversion systems of sodium fast reactors

    Författare :Anders Riber Marklund; Henryk Anglart; Horst-Michael Prasser; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics;

    Sammanfattning : Reaching the goals of Generation IV nuclear power is challenging. However, no less than six reactor concepts have been identified as capable of fulfilling the demands. Among these, the Sodium Fast Reactor (SFR), probably represents the most mature technology as about 20 SFR plants have been operated to this day. LÄS MER

  7. 20. Proliferation resistances of Generation IV recycling facilities for nuclear fuel

    Författare :Matilda Åberg Lindell; Sophie Grape; Ane Håkansson; Staffan Jacobsson Svärd; Roland Carchon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; safeguards; proliferation resistance; Generation IV; reprocessing; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : The effects of global warming raise demands for reduced CO2 emissions, whereas at the same time the world’s need for energy increases. With the aim to resolve some of the difficulties facing today’s nuclear power, striving for safety, sustainability and waste minimization, a new generation of nuclear energy systems is being pursued: Generation IV.
