   Sammanfattning : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. LÄS MER

3. 2. A multiwavelength approach to solar chromospheric heating : New insights from the millimeter continuum

   Författare :João Manuel da Silva Santos; Jaime de le Cruz Rodríguez; Jorrit Leenaarts; Petr Heinzel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sun; chromosphere; radiative transfer; waves; reconnection; Astronomy; astronomi;

   Sammanfattning : The chromosphere is an intermediate layer of the Sun's atmosphere where radiative equilibrium breaks down. The standard chromospheric diagnostics such as the Mg II h and k and Ca II H and K spectral lines are formed under nonlocal thermodynamic equilibrium (NLTE) and they are only partially sensitive to the local conditions.

4. 3. Extending a networked robot system to include humans, tiny devices, and everyday objects

   Författare :Md. Jayedur Rashid; Mathias Broxvall; Alessandro Saffiotti; Thomas Pederson; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Networked Robot System NRS ; Ecology of Physically Embedded Intellignet Systems; Middleware; Tiny Embedded devices; Network of distributed ubiquitous sensors and actuators; Object proxies; human proxie; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : In networked robot systems (NRS), robots and robotic devices are distributed in the environment; typically tasks are performed by cooperation and coordination of such multiple networked components. NRS offer advantages over monolithic systems in terms of modularity, flexibility and cost effectiveness, and they are thus becoming a mainstream approach to the inclusion of robotic solutions in everyday environments.

5. 4. Developing Entrepreneurial Competencies - An Action-Based Approach and Classification in Education

   Författare :Martin Lackéus; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; value creation; learning; venture creation; education; enterprise education; entrepreneurial competencies; Entrepreneurship education; emotional events; longitudinal case study;

   Sammanfattning : A question within entrepreneurial education that never seems to go out of fashion is “Can entrepreneurship be taught?”. To address this question, this thesis adopts the view that becoming entrepreneurial requires direct experience, and explores how learning-by-doing can be put to use in entrepreneurial education through action-based approaches.

7. 5. Developing geochemical and mineralogical proxies for the correlation of paleotsunami layers

   Författare :Linda Löwhagen; Malin Kylander; Stefan Wastegård; Eve Arnold; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine Geology; maringeologi;

   Sammanfattning : The catastrophic Indian Ocean tsunami of December 2004 raised urgent questions about the paleotsunami history in the region. Numerous studies have since been conducted to gain better understanding of the magnitude, frequency and impact of past tsunamis, especially around the coasts of the Indian Ocean. LÄS MER
