This paper explores the theoretical and practical uses and limitations of battle-field archaeology. The author aims to paint a big picture of the subject of exca-vating, understanding and theorising about historical battlefields done every day by archaeologists. Its approach places much weight on a quantity of examples rather than exploring specific excavations in every detail, in an effort to give the reader an understanding about how battlefield archaeology works. It stresses the need for battlefield archaeology as a way of obtaining and securing impor-tant archaeological and historical information before it is lost to science. The author tries to evaluate the subject in a critical and pragmatic fashion in order to establish a clear understanding about the facts of battlefield archaeology..

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige Väg och Anläggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and Länsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.

This paper deals with knives excavated in the Birka Garrison between 1997 and 2004, in a selection of 100 knives out of approximately 400. The aim is to measure and analyze the material to find out if certain elements in design points to a specific craft. Two groups of knifeblades can be seen, one with a convex bevel and one with a flat bevel of the blade. Considering osteological evidence, historical sources, and the main suitabillity of the knives, it is concluded that some of the flat beveled knives may have been used for crafting leather and fur, whereas the convex beveled knives are of an allround type..

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

This C-essay focuses its research on the taste of guitarplaying and non-guitarplaying soundengineers, in using single or dual microphone setups when recording electric guitar. It will be shown if there is a significant difference in taste when using one or two microphones between the two testsubject groups. Two classical microphone setups have been used for the test of this essay, which includes a blind listening test. The information in this test will benefit both guitarplaying and non-guitarplaying engineers by getting greater knowledge regarding what kind of microphone setups to use for different occations. The findings in this essay show in general, that guitarplaying and non-guitarplaying engineers between the ages of 19 - 26 don?t have a specific taste between single or dual microphone setups when subjected to the blind listening test..

The purpose of this study is to gain knowledge and a broader understanding for how pre-school teachers describe the importance of planned play environments including in what manner children are given influence. By qualitative interviews with five pre-school teachers from four different units I was able to gather data that shows how the planning process concerning a specific play environment had worked and why it looked as it did. The results show among other things that the pre-school teachers viewed the play environment as a vital part of the daily operation and pointed out that it was of vital importance that it came from the children?s interests. Depending on how the play environment had been organized and what its purpose was it offered different amounts of affordances..

After the deregulation of the Swedish pharmacy market customers can be lost due to stock-outs. Optimization of pharmacy inventory levels has thus become increasingly important. To minimize inventory costs while considering the cost of shortages the latter must be estimated. However, the shortage cost is very difficult to compute. Thus, the aim of this paper is to estimate the pharmacy-specific shortage cost parameter and its relation to other inventory costs.

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound.
