  1. 1. Computerized achievement tests sequential and fixed length tests

    University dissertation from Umeå : Statistiska institutionen, Umeå universitet

    Author : Marie H. Wiberg; Umeå universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; item respons theory; sequential analysis; statistical inference; power; optimal design; simulations; Statistik; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; Statistics; statistik;

    Abstract : The aim of this dissertation is to describe how a computerized achivement test can be constructed and used in practice. Throughout this dissertation the focus is on classifying the examinees into masters and non-masters depending on their ability. However, there has been no attempt to estimate their ability.

  2. 2. Optimal Design of Experiments for the Quadratic Logistic Model

    University dissertation from Stockholm : Department of Statistics, Stockholm University

    Author : Ellinor Fackle Fornius; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Logistic regression; D-optimality; c-optimality; Canonical design space; Maximum likelihood estimation; Sequential design; Stochastic approximation; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; statistik; Statistics;

    Abstract : Optimal design of experiments for binary data is the topic of this thesis. A particular logistic model including a quadratic term in the linear predictor is considered. Determining an optimal design for this model is complicated by the fact that the optimal design is dependent on the unknown true parameters. READ MORE

  3. 3. On Sequential Treatment Allocations in Clinical Trials

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Carl-Fredrik Burman; Göteborgs universitet.; Gothenburg University.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; treatment assignment; clinical trial; biased coin designs; balance of prognostic factors; sequential design; randomization test; expected p-value; deficiency; efficiency;

    Abstract : This dissertation treats baseline-dependent sequential designs of two-treatment parallel-group clinical trials. The treatment assignments are chosen in order to minimize the variance, in a linear model, of the treatment effect. This is done for each new allocation using a generalized biased coin design, or a non-randomized minimization' method. READ MORE

  4. 4. Computational support in product development applications from high temperature design and development

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Ola Isaksson; Luleå tekniska universitet.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion; Funktionella produkter; Functional Product Development;

    Abstract : In this thesis a new perspective to Computational Support in Product Development is presented. It is explained and discussed how computational simulation can be used to achieve shorter lead time and better quality in the product development process. READ MORE

  5. 5. Towards a methodology for integrated design of mechatronic servo systems

    University dissertation from Stockholm : KTH

    Author : Fredrik Roos; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechatronics; Servo Systems; Design Methodology; Integrated Design; TECHNOLOGY Engineering mechanics Construction engineering; TEKNIKVETENSKAP Teknisk mekanik Konstruktionsteknik;

    Abstract : Traditional methods for mechatronics design are often based on a sequential approach, where the mechanical structure is designed first, and then fitted with off-the-shelf electric motors, drive electronics, gearheads and sensors. Finally a control system is designed and optimized for the already existing physical system. READ MORE
