1. 1. Numerical Analysis of Partial Admission in Axial Turbines

   Författare :Narmin Baagherzadeh Hushmandi; Torsten H. Fransson; Liping Xu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : HTML clipboard Numerical analysis of partial admission in axial turbines is performed in this work. Geometrical details of an existing two stage turbine facility with low reaction blades is used for this purpose. For validation of the numerical results, experimental measurements of one partial admission configuration at design point was used. LÄS MER

3. 2. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

   Författare :Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

   Sammanfattning : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. LÄS MER

4. 3. Contingency in high-school students’ reasoning about electrochemical cells : Opportunities for learning and teaching in school science

   Författare :Karim Hamza; Per-Olof Wickman; Gregory J. Kelly; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electrochemistry; laboratory work; concept mapping; high-school; learning; teaching; pragmatism; practical epistemology analysis; contingency; discourse; misconceptions; alternative ideas; curricular materials; Subject didactics; Ämnesdidaktik; naturvetenskapsämnenas didaktik; Science Education;

   Sammanfattning : The thesis takes its departure from the extensive literature on students’ alternative ideas in science. Although describing students’ conceptual knowledge in many science areas, the literature offers little about how this knowledge enters into the science learning process. LÄS MER

5. 4. User Centered Design Methods must also be User Centered: A Single Voice from the Field. A Study of User Centered Design in Practice

   Författare :Erik Styhr Petersen; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; User Centered Design; Reflective Practice; Usability; Validity; Autoethnography;

   Sammanfattning : The present study concerns itself with the usability of the user centered design methodology, as this is defined by ISO 9241-210 (ISO9241-210, 2009) and other international standards: “[usability is the] extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use” (authors emphasis) (ISO9241-11, 1998; ISO9241-210, 2009, p. 3; ISO13407, 1999, p.

7. 5. Parallelized Program Analysis

   Författare :Marcus Edvinsson; Welf Löwe; Uwe Aßmann; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Computer Science; Datavetenskap;

   Sammanfattning : This thesis presents a framework for parallelized program analysis. It uses available parallel processing power in standard desktop computers to speed up static program analysis.Today, processor chip manufacturers produce single processor chips containing multiple cores, each with a processing power of previous single-core processors.
