There has been a remarkable progress in the development of organic electronic materials since the discovery of conducting polymers more than three decades ago. Many of these materials can be processed from solution, in the form as inks. This allows for using traditional high-volume printing techniques for manufacturing of organic electronic devices on various flexible surfaces at low cost. Many...

There are few studies on how social workers deal with cases regarding transnational surrogacy. Our study intends to contribute to filling this gap. In Sweden, surrogacy as an assisted reproductive technology method is not permitted. As a result, many prospective parents have turned abroad, mainly to India, for surrogacy. There are no laws regulating surrogacy in Sweden, and difficulties have ar...

The formation of dimethyl carbonate (DMC) from CO(2) and methanol with the dimer [n-Bu(2)Sn(OCH(3))(2)](2) was investigated by experimental kinetics in support of DFT calculations. Under the reaction conditions (357-423 K, 10-20 MPa), identical initial rates are observed with three different reacting mixtures, CO(2)/toluene, supercritical CO(2), and CO(2)/methanol, and are consistent with the f...

This project describes credit default swap (CDS) and shows how to calculate a fair value for such a contract. The stochastic evaluation of both the interest rate and the default intensity are first studied independent by using one factor a Vasicek model for a bond and a one factor model for the probability of no default. After validations the combined effect of stochastic interest rates and def...

A multi-agent approach to community detection is studied. There are three objectives in this thesis. The first is to investigate how the parameters of the model affect the community structure. To investigate this, the parameters are swept one at the time and the results are then compared to each other. The second objective is to study how the initial values of the agents affect the community st...

The floridly ornamented Persian singing style called avaz was studied, focusing on melody characteristics in melismatic pitch transitions, phonation types, and formant to harmonic relationships. Audio and EGG signals were simultaneously recorded from a professional male tenor range singer, who sang a Persian avaz song, scales, rapid tone reiterations, and alternations between two neighbouring t...

The immune system is composed of a complex network of different cell types protecting the body against various possible threats. Among these cells are T-helper (Th) cells type 1 (Th1) and type 2 (Th2), as well as T regulatory (Treg) cells. Th1 and Th2 are supposed to be in balance with each other, while Tregs regulate the immune response, by halting it when the desired effect, i.e. destroying t...

Electrochemical systems, which rely on coupled phenomena of the chemical change and electricity, have been utilized for development an interface between biological systems and conventional electronics. The development and detailed understanding of the operation mechanism of such interfaces have a great importance to many fields within life science and conventional electronics. Conducting polyme...

This thesis adresses issues associated with efficiently programming modern heterogeneousGPU-based systems, containing multicore CPUs and one or more programmable Graphics Processing Units (GPUs). We use ideas from component-based programming to address programming, performance and portability issues of these heterogeneous systems. Specifically, we present three approaches that all use the idea ...
