    Sammanfattning : Background: The Swedish driving licence test is a criterion-referenced test resulting in a pass or fail. It currently consists of two parts - a theory test with 65 multiple-choice items and a practical driving test where at least 25 minutes are spent driving in traffic. LÄS MER

    Sammanfattning : Silicon Carbide (SiC) is a wide-bandgap (WBG) semiconductor materialwhich has several advantages such as higher maximum electric field, lowerON-state resistance, higher switching speeds, and higher maximum allowablejunction operation temperature compared to Silicon (Si). In the 1.2 kV - 1. LÄS MER

  4. 4. Quality of Test Design in Test Driven Development

    Författare :Adnan Čaušević; Sasikumar Punnekkat; Henry Muccini; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; agile; software testing; test driven development; quality of tests; developer testing; test design quality; Computer Science; datavetenskap;

    Sammanfattning : One of the most emphasised software testing activities in an Agile environment is the usage of the Test Driven Development (TDD) approach. TDD is a development activity where test cases are created by developers before writing the code, and all for the purpose of guiding the actual development process. LÄS MER

  5. 5. Projective methods and longitudinal developmental research : considerations of data's nature and reliability

    Författare :Harald Janson; Bertil Mårdberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Longitudinal studies; projective methods; reliability; temporal stability; interrater agreement; epistemology; measurement; psykologi; Psychology;

    Sammanfattning : A projective method is viewed in the present work as a psychological test, by which is understood a standardized task that is set before a person, the solution of which is used for making inferences about psychological quantities. The present research was designed to shed light on several aspects of the usefulness of projective methods in longitudinal research, particularly with regard to reliability and to the distinction between measurement and theory-free empirical-comparison data.
