2. 1. A Statistical Approach to Estimate Thermal Performance and Energy Renovation of Multifamily Buildings : Case study on a Swedish city district

   Author : Martin Eriksson; Bahram Moshfegh; Shahnaz Amiri; Jan Akander; Sasan Sadrizadeh; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy signature; multifamily building; district heating; energy renovation; simulation; heat loss coefficient; balance temperature; base load; energisignatur; flerbostadshus; fjärrvärme; energirenovering; simulering; värmeförlustkoefficient; balanstemperatur; baslast; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Several climate and energy goals have been set in the European Union, one of them being to increase energy efficiency. In Sweden, a large potential for increased energy efficiency lies in the residential and service sectors, which account for about 40% of total energy use. READ MORE

4. 2. Finite Element Analysis and Design of Experiments in Engineering Design

   Author : Martin Eriksson; Innovation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element analyses; Predictive Design Analysis; Mechanical engineering design process; Design Of Experiments; Predictive Engineering;

   Abstract : Projects with the objective of introducing Finite Element Analysis (FEA) into the early phases of the design process have previously been carried out at the Department of Machine Design, see e.g. the Doctoral thesis by Burman [13]. These works clearly highlight the usefulness of introducing design analysis early in the design process. READ MORE

5. 3. Fundamentals of a Methodology for Predictive Design Analysis

   Author : Martin Eriksson; Innovation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Predictive design analysis; Generic design analysis process model; Confidence appraisal activities; Computer-based design analysis; Engineering design; Integration;

   Abstract : The rapid development of computer-based design analysis tools and methods such as the finite element method (FEM) within computational structural mechanics (CSM), computational fluid dynamics (CFD), and multi-body systems (MBS) during recent decades has fundamentally changed the way in which products are designed and developed. Among the many advantages observed in industrial practice, one can mention improved understanding of product properties and behavior, the possibility to optimize critical design parameters and to optimize parts as well as the entire product at a system level, the possibility to explore a design space during the synthesis activity, and a decrease of the need for physical testing and thus of the number of physical prototypes needed.

6. 4. Modelling the Evolution of Species’ Ranges

   Author : Martin Eriksson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Range expansions; Range margins; Population genetics; Evolutionary biology; Local adaptation; Environmental selection; Phenotypic plasticity; Computer simulations;

   Abstract : The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental conditions within species’ geographic ranges may change in the near-future. READ MORE

7. 5. Photoluminescence Characteristics of III-Nitride Quantum Dots and Films

   Author : Martin Eriksson; Per-Olof Holtz; Peder Bergman; Fredrik Karlsson; Volodymyr Khranovskyy; Yasuhiko Arakawa; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : III-Nitride semiconductors are very promising in both electronics and optical devices. The ability of the III-Nitride semiconductors as light emitters to span the electromagnetic spectrum from deep ultraviolet light, through the entire visible region, and into the infrared part of the spectrum, is a very important feature, making this material very important in the field of light emitting devices.
