   Författare :Sunney Fotedar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Decision-making; Robust efficient solutions; Discrete bi-objective optimization; Capacity planning; Discrete tri-objective optimization; Production planning; Coverage gap;

   Sammanfattning : In the aerospace industry, efficient management of machining capacity is crucial to meet the required service levels to customers and to maintain control of the tied-up working capital. We introduce new multi-item , multi-level capacitated resource allocation models with a medium--to--long--term planning horizon. LÄS MER

3. 2. On Falsification of Large-Scale Cyber-Physical Systems

   Författare :Johan Lidén Eddeland; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Test Coverage; Testing; Optimization; Simulation-Based Verification; Formal Requirements; Cyber-Physical Systems; Falsification;

   Sammanfattning : In the development of modern Cyber-Physical Systems, Model-Based Testing of the closed-loop system is an approach for finding potential faults and increasing quality of developed products. Testing is done on many different abstraction levels, and for large-scale industrial systems, there are several challenges. LÄS MER

4. 3. Closing the quality gap : investigating health system bottlenecks and quality improvement strategies for maternal and newborn care in Sub Saharan Africa, focusing on Tanzania

   Författare :Ulrika Baker; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : BACKGROUND: Despite substantial gains in survival in the past three decades, around 200,000 maternal deaths, 1 million newborn deaths and 1 million stillbirths occur annually in Sub Saharan Africa (SSA). The majority of these could be averted by effective medical interventions, but implementation in the context of under-resourced health systems is a challenge. LÄS MER

5. 4. Exploring socioeconomic inequality in educational opportunity and outcomes in Sweden and beyond

   Författare :Victoria Rolfe; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; inequality; socioeconomic status; opportunity to learn; student achievement; teacher characteristics; TIMSS; PISA;

   Sammanfattning : This doctoral thesis aims to explore Sweden’s achievement gap in international assessment and how this may have developed in the context of a network of educational inequalities. Theoretically grounded in the Model of Potential Educational Experiences (Schmidt, Raizen, Britton, Bianchi, & Wolfe, 1997), the thesis investigates how the relationship between the intended and attained curriculum is moderated by actions at the classroom level.

7. 5. Decomposition Methods for Combinatorial Optimization

   Författare :Uledi Ngulo; Torbjörn Larsson; Nils-Hassan Quttineh; Egbert Mujuni; Athanasios Migdalas; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis aims at research in the field of combinatorial optimization. Problems within this field often posses special structures allowing them to be decomposed into more easily solved subproblems, which can be exploited in solution methods. These structures appear frequently in applications. LÄS MER
