This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (

Smaller size and lower weight are always the targets of the power electronic product development. This work introduces two new topologies of auxiliary converters which have the feature of fewer components and fewer number of energy conversion stages comparing with the conventional auxiliary converter used in railway applications. The initial proposal of the proposed new topology is based on the id

In this letter we apply the Generalized Method of Moments (GMM), widely used in econometrics, to receivers operating with imperfect channel state information (CSI) of singleinput-multiple-output (SIMO) block-fading channels where a single pilot symbol is used. The GMM results in the standard maximum ratio combining (MRC) receiver, but with an improved channel estimate. Although not our goal at the

Background: Postoperative nausea and vomiting (PONV) is common after general anaesthesia, and corticosteroids are used in many protocols for enhanced recovery after surgery (ERAS). However, surgical techniques are developing, and ERAS protocols need to be reevaluated from time to time. Patients and method: In this study, we compared the effects of oral vs. parenteral corticosteroid administration

Significant saving potential is believed to exist in all economic activities of the private sector of MENA countries. However this potential is hardly explored in systematic ways. Particularly in the context of a country like Saudi Arabia, where the cost of water production is among the highest in the world, the incentives to examine this potential should be high. In 2007, a group of private secto

Popular Abstract in Swedish Syftet med avhandlingen var att utveckla en modell för ledarskap som påverkar målorienterad social kreativitet i organisationer. Modellen, på engelska benämnd Generative learning management, har två dimensioner: målstyrning genom tilldelning och decentralisering av beslutsrätten över strategiutveckling för att nå målen i analogi med parallell distribution. I rent praktiA main purpose of this thesis was to develop a model of leadership style named Generative Learning Management (GLM), thought to influence goal-oriented interpersonal creativity in organizations, and to test this model. Creativity is a complex consisting of both novelty and usefulness and it is a general mental ability that is determined by the interplay between different regions in a normally func

A frequency synthesizer applied to 1000Base-T Ethernet transceiver as well as 10/100Base-T mode is described. A dynamic voltage-mode phase interpolator is used and a more precise analysis and calculation on degressive interpolating resistors are given. The design not only meets the transmitter's requirement of very accurate rising (falling) edge control but also offers much finer time-interval clo

When the wavelength is much larger than the typical scale of the microstructure in a material, it is possible to define effective or homogenized material coefficients. The classical way of determination of the homogenized coeffi- cients consists of solving an elliptic problem in a unit cell. This method and the Floquet-Bloch method, where an eigenvalue problem is solved, are numerically compared with

The extension of businesses to incorporate the provision of function as a service in supplement to standalone products is an ongoing movement in manufacturing industry. In short, this means that the development intent should be guided by the need of ‘performance in use’ that the customer wants, e.g. thrust rather than an engine. By this, the established knowledge base challenges the development te

The goal of the presented work is to provide support for software requirements engineering domain experts in modeling combinatorial optimization problems that arise in requirements prioritization and release planning. A Domain-Specific Language (DSL), called reqT/CSP, is presented that integrates constraints modeling with requirements modeling. The DSL is embedded in the object-functional Scala pr

We consider the propagation in macro- and microcellular environments for systems with multiple antennas at both transmitter and receiver. We consider the important propagation effects that lead to (i) interdependency of directions-of-arrival and directions-of-departure, (ii) large delay and angle dispersion by propagation via far clusters, (iii) rank reduction of the transfer function matrix. We p

Specific advantages with Particle Induced X-Ray Emission are: its (1) multielemental capability, especially when combined with nuclear techniques for lighter elements, (2) speed, (3) low detection limits for small samples and (4) accuracy. To make full use of these advantages, analytical parameters have to be chosen optimally and the facility to be carefully designed. This paper describes an exper
