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

Looking ahead, the quest for environmental sustainability may turn out to be the most important political challenge of the twenty-first century. Though consensus is growing about some of the policy objectives like climate stability, political attitudes to these issues remain highly contested. Political parties seem to differ on both ontological assessments (how severe are the problems) and remedia

A new reactor type has been designed by Alfa Laval AB,the open plate reactor (OPR). It combines good mixing with high heat transfer capacity. With the new open plate reactor, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a model from first principles is derived. The paper concerns the control properties of the platere

It is disclosed a circuit for extracorporeal blood treatment in which a flow-inverting device is interposed between a blood treatment unit and a blood pump placed on an artery branch connected with a vascular access of a patient. The flow-inverting device allows the blood flow within the filtering unit to be kept unchanged even following an inverted circulation in the patient-side artery and vein
