  1. 21. Washing Machine Design Optimization Based on Dynamics Modeling

    Författare :Thomas Nygårds; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experiments; Multiobjective Optimization; Modeling; Vibration dynamics; Washing machine; Suspensions; Semi-active control.; Automatic balancing;

    Sammanfattning : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

  3. 22. Assessing Reusability in Automated Acceptance Tests

    Författare :Mohsin Irshad; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Context: Automated acceptance tests have become a core practice of agile software development (e.g. Extreme Programming). These tests are closely tied to requirements specifications and these tests provide a mechanism for continuous validation of software requirements. LÄS MER

  4. 23. Seasonal change in defensive coloration in a shieldbug

    Författare :Aleksandra I. Johansen; Gabriella Gamberale-Stille; Birgitta S. Tullberg; Graeme Ruxton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shield bug; colour change; protective coloration; cryptic; aposematic; behavioural change; etologi; Ethology;

    Sammanfattning : Protective coloration such as aposematism and crypsis occurs in many insects but only a few species alter their defensive strategy during the same instar. We hypothesize the adult shield bug Graphosoma lineatum with an alternating black and non-melanised longitudinal striation exhibit such a change in defensive coloration. LÄS MER

  5. 24. Factors influencing physical activity in patients with venous leg ulcer

    Författare :Kirsti Skavberg Roaldsen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background and Aim: Venous leg ulcer is a chronic condition characterized by a cyclical pattern of healing and recurrence leading to pain, disability, inactivity and reduced health. Physical activity is beneficial for venous circulation and general health, but knowledge is needed of determinants of physical activity and of possibilities for patients with leg ulcer to be physically active.

  7. 25. Autonomous Vehicle Maneuvering at the Limit of Friction

    Författare :Victor Fors; Lars Nielsen; Björn Olofsson; Jan Åslund; Christian Gerdes; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Without a driver to fall back on, a fully self-driving car needs to be able to handle any situation it can encounter. With the perspective of future safety systems, this research studies autonomous maneuvering at the tire-road friction limit. In these situations, the dynamics is highly nonlinear, and the tire-road parameters are uncertain. LÄS MER
