  1. 1. Friction in metal powder pressing : measurement and characterisation

    Author : Naghi Solimanjad; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The present work describes different methods for measuring and characterisation of friction in powder compaction process. A new test apparatus has been developed and presented which gives possibility of directly measurement of coefficient of friction during pressing from low to relative high density. READ MORE

  2. 2. Learning about the unobservable : The role of attitudes, measurement errors, norms and perceptions in user behaviour

    Author : Juan Manuel Lorenzo Varela; Yusak Susilo; R. Daniel Jonsson; Maria Börjesson; Soora Rasouli; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Attitudes; Measurement errors; Discrete choice analysis; Latent variables; Model misspecification; Normative beliefs; Rail factor; User perceptions; Social norms; Value of travel time savings; Transportvetenskap; Transport Science;

    Abstract : Unobservable factors are important to understand user behaviour. Moreover, they contain information to help design services that willsolve today’s challenges. Yet, we have barely scratched the surface ofthe underlying mechanisms ruling user behaviour. READ MORE

  4. 4. Bufferbloat and Beyond : Removing Performance Barriers in Real-World Networks

    Author : Toke Høiland-Jørgensen; Anna Brunström; Per Hurtig; Luca Muscariello; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bufferbloat; AQM; WiFi; XDP; TSQ; Flent; network measurement; performance evaluation; fairness; queueing; programmable packet processing; Computer Science; Datavetenskap;

    Abstract : The topic of this thesis is the performance of computer networks. While network performance has generally improved with time, over the last several years we have seen examples of performance barriers limiting network performance. In this work we explore such performance barriers and look for solutions. READ MORE

  5. 5. Motivational aspects of test-taking : measuring test-taking motivation in Swedish national test contexts

    Author : Eva Knekta; Hanna Eklöf; Anna Sundström; Rolf Vegar Olsen; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Test-taking motivation; Swedish national tests; validity; expectancy-value theory; task value; expectancies; young adolescents; self-report instrument; interview; structural equation modelling; test stakes; didactics of educational measurement; beteendevetenskapliga mätningar;

    Abstract : The overall aim of the work underlying this thesis was to improve the understanding of students’ test-taking motivation in connection to achievement tests for young adolescents. The thesis includes four studies and a summary. All four studies explore test-taking motivation and are all connected to validity in one way of another. READ MORE
