Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

I detta examensarbete har en generell metodik skapats för testning av styrsystem för pumpar. Testmetodiken beskrivs med modeller som på ett strukturerat sätt går igenom testningens förberedelse och utförande. Metodiken tillämpas sedan genom en stegvis mall för hur testningen går till praktiskt.En metod för att optimera antalet tester presenteras. Denna metod minskar antalet tester genom att använda de mest prioriterade signalerna som skickas mellan styrsystem och pump. Denna prioritering sker genom en viktning av hur viktig signalen är för systemet.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

The aim with this essay is to find out what the expected changes in the subject physics will lead to for teachers and their pupils in ?gymnasiet?. The new fields we have chosen to focus on are electronic structure of condensed matter, nanotechnology and material physics. By studying earlier used curricula and textbooks, we illustrate what teachers may have come into contact with in their teaching careers. The main focus lies on what teachers claim to know about the fields mentioned above and if there is a need for further education.

A business is always dependent on its customers. It is therefore important to ensurethat customers are satisfied with the product and the warranty included.The study was conducted in cooperation with the building contacting companySkanska Sweden. The aim is to use interviews to collect and process experiences in order to answer the question: How should the recovery process in the construction industry be performed to ensure a professional handling of warranty? The results have shaped my conclusions and I have turned them into a proposal that companies in the industry can benefit from. The study indicates that the industry is not geared for a five year warranty, which was introduced in 2004 and 2006.

This report describes the process of developing a user-friendly and responsive archive website. The website is a Hi-fi prototype and was created for the company JG Communications, to serve as an archive for their customers? style guidelines. To create this website I have used HTML5 and CSS3 to make it responsive for various computer screens. I have also used PHP and some JavaScript to make some of the functions and Adobe Photoshop and Illustrator to make design elements for the prototype.

This study is an analysis of a survey that harvester operators working for SCA Ångermanland Skogsförvaltning have been participating in. The purpose of this study is to try to show the harvester operators opinion about the forestry planning that SCA provides. Hopefully will this information lead to suggestion about what part of the forestry planning needs to be improved, if any is needed? Unfortunately only 30 / 60 questionnaire has been returned so no conclusion can be made, except about those who have answered the survey. The answers of the survey indicate a number of areas that needs to be improved. The marked routes needs to be more visible and the education about timber landings must be enhanced.

The web has a broad affect on the global economy and can among other things be used for web based information systems (WIS). These systems have grown from being used as a market platform to support all activities in the work of an organisation of today. To survive in a turbulent competitive environment, companies must start to cooperate with their customers instead of just collaborate with them. Can an IT-consultant company use a WIS as a tool for keeping in contact with existing customers to attain this cooperation? A WIS could strengthen the relation between customer and supplier and through that have a possibility to increase the customer use since it can facilitate business processes and imply that services can be offered in a new way.

This research is about the experience educationalists have of children encountering mathematics in a preschool. What is the impact of introducing mathematics in preschool? How do educationalists work with mathematics and how do they experience the children?s interest in mathematics?  The aim of this degree project is to examine how educationalists experience children´s interest in mathematics when they encounter mathematics at an early age. The degree project is limited to educationalists and children within a preschool located north of Stockholm.This research seeks answers to the following questions at issue. Does an early encounter with mathematics in preschool lead to increased interest in mathematics among children?  How can educationalists in preschool work in a appropriate way with mathematics to stimulate children to develop within mathematics and to increase their interest? How does educationalists in preschool experience children´s interest in mathematics?Theories by Piaget, Vygotskij and Dewey were used as well as former research in this subject.To answer the aim and the questions at issue in this research, three interviews was conducted with educationalists at the preschool and recorded with a Dictaphone.

The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics.This thesis addresses the two most common types ofgeosynthetics used in modern road construction, namely geogrids and geotextiles.The most common use of geogrids is reinforcement of poor subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid?s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load spreader.Road contractors often face a choice of whether geogrids and/or geotextiles areappropriate in a particular road project and also how much profit the choice mightbring. This phase in the tender calculation process is the intended scope of thisthesis.The thesis deals with both the "hard" cost-function aspects and the "softer" values e.g.

Touch that is performed in a sensitive and gentle way can be a good complement in caring. To be stricken with illness can involve that the individual feels powerlessness and to have no control over the own body. This could lead to both psychical and physical suffering. To strength health is one of the nurses' responsibilities and to touch can be one way. The aim of the study was to describe patients' experience of the effects of touch.

An array of different retinal disorders is present as a threat in quite a number of dog breeds. These often lead to profound visual impairment or blindness. Many of the disorders are genetic, and they are, in Sweden as well as in other countries, subject to breeding programmes. The anatomy of the eye and the retina, as well as current examination techniques (ophthalmoscopy, electroretinography (ERG) and genetic analysis) are described. The more common retinal disorders encountered in dogs in Sweden are discussed: retinal dysplasia, generalized progressive retinal dystrophy, retinal pigment epithelial dystrophy, collie eye anomaly, sudden acquired retinal degeneration, retinal detachment and choroiditis. The possibly affected breeds are listed. The value of diagnostic findings is discussed and current advances on the subject in ophthalmologic research are accounted for..

The objective of this project was to develop an application for mobile phones using the Android operating system. The main goal was, with the help of GPS, to pinpoint locations, measure distance traveled and illustrate the progress on a map. Functionalities for just showing the map, fetching addresses and saving to a database was also implemented. The result of the work was a proper application, called MeasureApp, that fulfills the goals set in the planning stages of the project. MeasureApp can be used to measure distances where accuracy is not a main factor, i.e walks or runs.

Homework is and has always been a part of school work. It may take a lot of time from the pupils? leisure. Despite this, you cannot find anything written about homework in the curriculum. How can this be? Is homework necessary and what is its function?The purpose of this study is to find out how a few teachers in primary school reason about homework.  What are their attitudes towards homework and what functions do they see?To get an answer to this I studied literature and research reports, and did four qualitative interviews with teachers who teach grades 1-6.The results show that all the teachers give homework to their pupils, but their opinions about homework differ.
