2. 11. Comprehensive numerical analysis of stress state in adhesive layer of joint including thermal residual stress and material non-linearity

   Author : Nawres Jabar Al-Ramahi; Roberts Joffe; Janis Varna; Lars Mikkelsen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-lap adhesive joint; Double-lap adhesive joint; Unbalanced bi-material DCB; Residual thermal stresses; Finite element method; Crack path; Crack closure; Polymeric Composite Materials; Polymera kompositmaterial;

   Abstract : The main objective of this work is to improve understanding of the stress state in the adhesive layer of bonded joints and identify key parameters which govern performance of adhesive joints. This information is crucial for the prediction of the failure initiation and propagation with the further estimation of the durability and strength of adhesively bonded structures. READ MORE

4. 12. Adaptive Baseband Pro cessing and Configurable Hardware for Wireless Communication

   Author : Rakesh Gangarajaiah; Integrerade elektroniksystem; []
   Keywords : Wireless receivers; baseband processing; LTE-A; MIMO; OFDM; carrier aggregation; channel preprocessing; adaptive signal processing; non-linearity mitigation; massive MIMO;

   Abstract : The world of information is literally at one’s fingertips, allowing access to previously unimaginable amounts of data, thanks to advances in wireless communication. The growing demand for high speed data has necessitated theuse of wider bandwidths, and wireless technologies such as Multiple-InputMultiple-Output (MIMO) have been adopted to increase spectral efficiency.

5. 13. On the Value of Customer Loyalty Programs - A Study of Point Programs and Switching Costs

   Author : Henrik Sällberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; loyalty programs; point programs; switching costs; Computer science; Datavetenskap; Economic Information Systems; Ekonomiska informationssystem;

   Abstract : The increased prevalence of customer loyalty programs has been followed by an increased academic interest in schemes. This is partly because the Internet has made competition 'one click away'. It is also because information technology has made it more economical for firms to collect customer information by way of loyalty programs. READ MORE

6. 14. Addressability and GHz Operation in Flexible Electronics

   Author : Negar Sani; Magnus Berggren; Isak Engquist; Dago M. De Leeuw; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The discovery of conductive polymers in 1977 opened up a whole new path for flexible electronics. Conducting polymers and organic semiconductors are carbon rich compounds that are able to conduct charges while flexed and are compatible with low-cost and large-scale processes including printing and coating techniques.

7. 15. A new non-linear GARCH model

   Author : Gustaf E. Hagerud; Handelshögskolan i Stockholm; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This dissertation contains four papers in the field of financial econometrics. In the first paper, A Smooth Transition ARCH Model for Asset Returns, a new class of ARCH models is introduced. The model class allows for non-linearity in the equation for the conditional variance.
