1. 1. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty

   Författare :Dženan Hozić; Carl-Johan Thore; François-Xavier Irisarri; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Optimization; Composite Structures; Topology Optimization; Multi-material Optimization; Material Uncertainty; Robust Optimization; Composite Structure Optimization; Design Optimization; Composite Material;

   Sammanfattning : Composite materials are known to have superior stiffness and strength properties per unit weight compared to metallic materials. These properties and the ability to tailor the mechanical properties of composites is the main motivation for choosing composite materials for structural components. LÄS MER

3. 2. Mining Futures : Predictions and Uncertainty in Swedish Mineral Exploration

   Författare :Tobias Olofsson; Patrik Aspers; Gholamreza Azarian; Trine Pallesen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Uncertainty; Risk management; Sociology of the Future; Valuation; Justification; Mineral Exploration; Second Nature; Natural Resources; Sociologi; Sociology;

   Sammanfattning : Any forward-oriented enterprise must somehow manage the challenges posed by uncertainty and with its distant temporal horizons, high stakes, and low probability of success, mineral exploration is a good illustration of this general rule. Based on a combination of interviews, observations, and archival research, this thesis investigates how explorationists use predictions to manage the material complexities and the uncertainties that contribute to determining the future minability of mineral deposits.

4. 3. Den nödvändiga osäkerheten : Elevers perspektiv på respekt i relationer i skolan

   Författare :Susanne Hansson; Solveig Hägglund; Bo Dahlin; Åsa Söderström; Karin Sporre; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; respect; trust; relationships; student perspective; school; the ethical demand; K.E. Løgstrup; Education; Pedagogik;

   Sammanfattning : This thesis deals with students’ views on respect as an element in their relationships with teachers and peers. The purpose of the thesis is to gain further knowledge of relationships in school by applying concepts of the theory of ethical demand in the analysis of students’ descriptions of respect in their relationships with their teachers and peers.

5. 4. MANAGING PROJECT UNCERTAINTY BY USING AN ENHANCED RISK MANAGEMENT PROCESS

   Författare :Rolf Olsson; Mats Jackson; Mats Deleryd; Björn Fagerström; Johannes Halman; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Risk management; uncertainty; project management; Other industrial engineering and economics; Övrig industriell teknik och ekonomi; Innovation och design;

   Sammanfattning : An increasing number of companies are focusing their efforts on project management. Project management is frequently used as an enabler for meeting an uncertain and turbulent environment. Consequently, the overall effectiveness of the project management process is essential for long-term profitability. LÄS MER

7. 5. Towards a model for managing uncertainty in logistics operations – A simulation modeling perspective

   Författare :Ola Johansson; Förpackningslogistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk; uncertainty; simulation; supply chain; logistics;

   Sammanfattning : Uncertainty rules supply chains. Unexpected changes constantly occur on all levels; strategically through globalization, introduction of novel technology, mergers and acquisitions, volatile markets, and on an operational level through demand fluctuations, and events such as late arrival of in-bound material, machine equipment breakdown, and quality problems.
