Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

Förmedling : från Arkeologisk Dokumentation till Publik Presentation
The aim of this study is to investigate how new knowledge, discovered and translated by the archaeologist, is transferred to the public by examining the question posed to the archaeologist by ?la?nsstyrelsen,? the county administration office.Since there can be no mediation of knowledge without an understanding of its perception, I pay a visit to the cognitive sciences in order to answer what knowledge is and how it functions in regards to contract archaeological results.I argue that the current structure of mediation, in regards to archaeological knowledge, is in need of the same quality control that is demanded by the contractors in regards to standard archaeological procedures. When presenting archaeology to the public, consideration needs to be paid to the different targets groups of society. The importance of national directions rather than regional translations for mediation of archaeology is stressed by the author. This needs to be carried out through a change of the questions posed to the contracted archaeologists by the county administration in their ?fo?rfra?gningsunderlag,? the order specification for archaeological investigations. .
Vitamin A och E i relation till hästutfodring :
The purpose of this study was to examine vitamin A and E in equine nutrition and especially in relation to forages. A literature review was conducted to examine factors that influence the level of vitamins present in forage, the vitamin A and E requirement of horses, and the absorption of vitamin A and E in horses. The influence of DM level on alpha-tocopherol and beta-carotene content in ensiled forage was investigated in a controlled ensiling study using baled silage and haylage. The results from the ensiling study were combined with data of vitamin A and E concentrations collected from literature. Calculations were done to theoretically establish how well the vitamin content in ensiled forage can cover the
maintenance requirements of vitamin A and E in horses.

FE safety analysis of a high speed wood planer cutter. An alternative method to achieve the requirements of EN847 standard
In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.
Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager
This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.
Anser kunden att ett WIS kan gör denne vis? : Kundens önskemål om informationsinnehåll i ett webbaserat informationssystem
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.

Spatial TDMA in Ad Hoc Networks with Antenna Arrays
In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.
Utveckling av Web Service för hantering av öppna autentiseringsnycklar
Utvecklingen går mot alltmer distribuerade IT-system, där ett flertal datorer kommunicerar med varandra. Detta gäller även försvarsmaktens ledningssystem. I dessa öppna och distribuerade system är olika säkerhetsfunktioner kritiska. En av dessa är att kunna verifiera identiteten hos den part som kommunikationen sker med. Detta görs oftast med hjälp av asymmetriska kryptooperationer, där identiteter kan verifieras med hjälp av öppet publicerade autentiseringsnycklar.
Förpackningslogistik på Haldex Traction Systems AB
the most obvious problem at Traction today is the in-between handling that demands much time and resources. The reason is that the packages are not designed with handling in mind. Several of the packages of today also have a poor degree of utilization that means there is room for a fewer number of articles. That in turn means more packages, more transports, more storage space and more staff. On the basis of a specification of demands ? which take quality and environmental influence, as well as transport, handling and economy in account ? we have developed suggestions on new packages that will facilitate handling and lower the total costs, The time of handling will in some cases abbreviate to just a few seconds with the new packages.
"Varder lekare sårad..." : Musik, politik och ideologi i tidigmedeltidens Norden
The aim of this paper is to illuminate and discuss the political and ideological aspects of Early Medieval Nordic music. Due to shortage of sources, this issue has been overlooked until now. Did Early Medieval Nordic music meet the requirements for political and ideological use? In what ways could music potentially be used politically and ideologically? Was music used as a political and ideological tool? This is examined by a contextual analysis combining music history and historical archaeology. The survey consists of a background account, focusing on the potential of music and some requests for political use, and three case studies, where musical reflections of societal tensions is investigated in folk music lyrics, Icelandic sagas and church art.
