Gaza has several water problems; inefficient water use by the agricultural sector, limited fresh water supply and high water demand, groundwater contamination, seawater intrusion and shortage of electricity. More water and electricity for the future development of Gaza that will give better life; a significant value of water should be added to the Palestinians living in blocked Gaza; more employme
Protection of systems with series compensated lines is considered to be one of the most difficult tasks for relay manufacturers and utility engineers. Protection and control of surrounding circuit elements, particularly transmission line protection, needs to be adapted to the variations introduced by these devices. Fixed series capacitors and thyristor controlled devices introduce harmonics and no
In an industrial plant, availability is an important factor since increased availability often gives an increase of final production, which in many cases means an increased profit for the company. The purpose of using buffer tanks is to increase the availability either by separating production units from each other or by minimizing flow variations. However, the methods for achieving this goal is n
In this paper we address link dimensioning and routing problems related to the area of resilient network design. We present two network design problems that assume different flow restoration schemes used to cope with network failures. In both cases we allow bifurcation of traffic flows in the normal (failure-less) network state. In the case of a failure, we assume that affected primary flows (i.e.
Syftet med uppsatsen var att studera hur börsnoterade fotbollsklubbars aktier reagerar vid spelartransaktioner och vid kvalifikationsmomentet till Champions League. För att genomföra denna undersökning använde vi oss av en kvantitaitv metod, där vi studerade spelartransaktioner och kvalifikationsmomentet till Champions League enligt Event study teknik. Empirins utgörs av börskurser från de fyra kl
IntroductionRecreational hunting in Sweden can be depicted as being embedded in two different but overlapping cultural and socio-economic contexts. One is the traditional non-commercial and stewardship-oriented form hunting, in Swedish called ‘allmoge’ hunting. It is characterised by a democratic hunting tradition where the local hunting team is ascribed a main role in wildlife management. These tThe paper is based on a study of hunting tourism enterprising in Sweden. The study examines how hunting tourism businesses in Sweden navigate in a complex social, economic and moral environment. The aim of the present paper is to identify how tensions between a market- oriented value sphere and a value sphere based on friendship- and community reciprocity are played out in hunting tourism entrepre
Aim of the study was to access how individual's motives for participation in sports impact on self-reported outcomes 2 years after an anterior cruciate ligament injury. Based on a longitudinal cohort study, this secondary analysis present data from the Knee Anterior Cruciate Ligament, Nonsurgical versus Surgical Treatment (KANON) study, a randomized controlled trial. At baseline, 121 patients reco

The topic of this thesis is the optimal control of transportation networks. The problem studied is a dynamical extension of a classical problem in economics, in which the objective is to distribute goods to maximize welfare, whilst satisfying constraints on production and consumption. The main contribution is to show that for a class of welfare functions and dynamics, the optimal control is highly
