The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Background: First Line Managers are expected to create a health promoting work environment. Research has shown that the prerequisites for accomplishing a health promoting leadership are not always the best. Aim: The aim was to elucidate the prerequisites for a health promoting leadership as First Line Manager at a University hospital in Sweden based on competence, role, support structures and own durability. Results: First Line Managers at the chosen hospital seems to have rather good conditions for conducting a health promoting leadership. All respondents did have a university degree and most thought that their competence corresponded well with the role.

Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative. To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating problems. This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality. The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles. The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.

Have you ever had problems sorting your cables, are the winders you use too big and crude then the EC-winder is the product for you. The EC-winder concept is a compact and intelligent winder for home application. Its simple design and subtle looks enables it to blend in with the surrounding environment. Its function is designed so that it with ease can be handled by any one after only a couple of instructions. You simply thread the cable trough the opening on the winder and then you rotate the upper part until the cable reaches the desired length. After use the winder can be opened to enable easy extraction of the cable..

The purpuse with this work is to see if there is a possibility to buy a farm with a low amount of own capital. We have been doing budgets for five farms with different kind of productions. Some of the farms in this work are possible to buy with a low amount of capital but if you start without any money you will run into problems with the bank. The bank is not very pleased with fully financed projects; they would recommend an own capital of at least 10-20%. The farms with the best budgets were farms with animals..

In the end of the 80´s the area of system development moved into a new era. As a consequence many new methods and development models emerged which in many cases resulted in problems when choosing system development models and methods. As a result of these problems the today standardized modeling language UML (Unified Modeling Language) was created. UML is tailored to support many different types of projects. This is possible because of UML?s capacity to be adjusted and adapted to a specific company environment.The purpose of this bachelor thesis is to investigate how and why companies use UML and what experiences and opinions those who use UML have of using UML in practice.

I dag lider ca 25-35 % av skolungdomar av psykisk ohälsa. Tidigare forskning har visat att denna ohälsa beror på att ungdomar sover alltför lite, vilket i sin tur associerats till en ökad användning av sociala media. Orsakssambanden är emellertid oklara och varierar mellan studier. Av den anledningen genomfördes en enkätstudie på gymnasielever, för att ytterligare belysa hur sambanden ser hos svenska ungdomar.I undersökningen användes två frågeformulär bestående av en reducerad version av KASAM, ett sömnformulär, samt frågor angående sociala media.I studien deltog 51 elever (M: 18.0 år, SD 0.35), varav 22 kvinnliga och 28 manliga elever i ÅK 3. Resultatet visade att cirka hälften av eleverna (49 %) ansåg sig sova signifikant kortare tid än vad de önskade (p<0.0001).

Organising knowledge in a corporate environment : a case study at the development departments of Ecophon ABThe purpose of this master's thesis is to investigate how three development departments of a technical firm could organise their collection of documents and information resources to improve their management of information. Three sets of questions have been posed: 1) How does the target group of engineers deal with information, and what problems can be identified in this process? 2) What does their collection of resources consist of, how is it organised, and what problems are apparent? 3) How can principles of knowledge organisation be applied in a corporate environment?The investigation has been carried out as a case study. Three main methods of collecting empirical data have been used: surveys, unstructured interviews and collection observations. The results of the study have highlighted three major problem areas: the collection's lack of structure and searchability, the absence of policy regarding how employers should deal with information, and the inadequate knowledge among staff on how to search for, use and disseminate information.By looking at previous research on knowledge organisation, we have been able to draw conclusions regarding how the target group could organise and manage its information and knowledge in order to achieve greater efficiency in dealing with information and carrying out work tasks.

This report describes the construction process and the aspects that should be taken into consideration. It includes models of decision and how these can be used in practice. Planning of a building project is very important for a successful execution. This will be the foundation of problems that will occur during the production. In the planning process people with different positions, search for the best suitable building methods.

Hemmasittare is a new term for children and youths with a history of long term truancy. As the term indicates these youths spend most of their time in their homes. This often results in them being socially alienated and the loss of their earlier social network. The consequences of hemmasittande and social alienation are many and include not only a deficient social network but also psychological and physical problems. Research has shown that many of these problems follow on through into adult life.

Ala sawmill in Ljusne, Hälsingland, has increased its flow through the sawing plant during the last couple of years. The problem now is the sorting plant, as this part of the mill is now slower than the rest. A close analysis of the sorting plant was therefore necessary to be able to increase the flow through. The aim of the project was to find solutions that can lessen downtime and increase flow. The goal was to increase the flow from 650 to 925 logs through the sorting plant per hour.

?African Solutions to African Problems? är en av Afrikanska Unionens nya ledord. Denna vilja om att ta mer ansvar för den afrikanska kontinenten och kunna agera som en säkerhetsaktör har resulterat i en ny säkerhetsdoktrin. För att kunna agera som aktör på den internationella arenan krävs att vissa förutsättningar existerar enligt en modell framtagen av Gunnar Sjöstedt. Dessa strukturella och institutionella förutsättningar kommer i denna studie att undersökas för att analysera huruvida AU kan agera som säkerhetsaktör.

Bakgrund: Sömn är ett mänskligt grundläggande behov och bör därför tillgodoses hos patienter som vårdas på sjukhus. Patienter som vårdas på intensivvårdsavdelningar upplever dock ofta upprepade avbrott på sömnen och sömnbrist vilket kan leda till både fysiska och psykiska negativa konsekvenser. Intensivvårdsmiljön med dess oljud, starka belysning och frekventa vårdrelaterade interaktioner leder ofta till oförmåga hos patienterna att få en adekvat sömn. Syfte: Att belysa olika interventioner sjuksköterskan kan tillämpa för att förbättra sovmiljön och sömnkvaliteten hos patienter som vårdas på en intensivvårdsavdelning. Metod: En litteraturöversikt med grund i analys av kvantitativ forskning.

This bachelor thesis contains the findings of an investigation into the laying of wedge sawn wood flooring. The advantage of wedge sawn wood flooring is the usage of more material from each board reducing waste. The boards follow the natural profile of the tree where the root part of the board is wider, and the top part is narrower. The technique involves placing boards side by side with adjacent boards in opposite directions. The thick base of one board is neighbored by the narrow top of another, this creates a pattern of wedges in alternating directions, known as a ?root and top? system. Existing literature into this type of flooring is sparce.
