  1. 1. Specifying Safety-Critical Heterogeneous Systems Using Contracts Theory

    Author : Jonas Westman; Mattias Nyberg; Mats Heimdahl; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; Contracts; Heterogeneous Systems; Safety; Architecture; Requirements; Specification; Elements; Compositional; IEC 61508; ISO 26262; Kontrakt; Heterogena System; Säkerhet; Arkitektur; Kravhantering; Specifiering; Element; Kompositionell; IEC 61508; ISO 26262; Machine Design; Maskinkonstruktion;

    Abstract : Requirements engineering (RE) is a well-established practice that is also emphasized in safety standards such as IEC 61508 and ISO 26262. Safety standards advocate a particularly stringent RE where requirements must be structured in an hierarchical manner in accordance with the system architecture; at each level, requirements must be allocated to heterogeneous (SW, HW, mechanical, electrical, etc. READ MORE

  2. 2. Robust energy management for IoT machine elements

    Author : Fredrik Häggström; Jerker Delsing; Jonny Johansson; Saul Rodriguez; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting; Rolling element bearing; Energy Storage; Industrial Electronics; Industriell elektronik;

    Abstract : Advancements in semiconductor technology have reached the point at which ambient energy in the surrounding environment can power sensors and microprocessors. This capability enables new strategies for energy management, which are necessary to continue the sensorization of our environment. READ MORE

  3. 3. Wear resistant low friction coatings for machine elements

    Author : Olle Wänstrand; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : By the introduction of machine elements made of light metals, e.g. Al or Mg alloys, which are coated with a material providing high wear resistance and low friction coefficient, both economical and environmental benefits can be gained. A high resistance against wear results in increased lifetime and lower costs for spare parts and maintenance. READ MORE
