This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.

Open source software has recently been discussed, not least in media as a revolution in IT. A number of advantages have been listed in changing proprietary software into open source software. Examples of such pros are no expenses for license fees and improved efficiency. In spite of this, few users have made this change. One of the reasons is a distrust of the quality in open source software.

Detta examensarbete har haft till syfte att åskådliggöra eventuella skillnader och/eller likheter i den upplevda användbarheten vid användandet av en webbplats skapad via mobile first design och desktop first design. Målsättningen med examensarbetet har varit att ta fram en hifi-prototyp, skapad utifrån mobile first design, som visualiserade ett designförslag för flygfotoföretaget HimlaFotos startsida. Jämförelsen har utgått ifrån en egendefinierad version av begreppet användbarhet baserad på ISO:s definition, där användbarhet består av tre faktorer; kraftfullhet, effektivitet och tillfredställelse. För att samla in data om den upplevda användbarheten har användartester genomförts. Flera likheter har identifierats gällande användbarhetsmåtten kraftfullhet och effektivitet, medan skillnader har funnits vid måttet för tillfredställelse.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of the feeding can be very simple or include high degrees of mechanisation. Three different farms, representing different levels of mechanisation are presented. Descriptions and analysis of the feeding systems including mechanisation, work effort and estimations of the feed waste are made on each farm. The herd with the most advanced feed mechanisation included a rolling feed band and mix wagon. The other farms were partly or little mechanised including ad lib feeding from big bales and manual distribution of hay and concentrates. The most mechanised farm was able to feed a large herd of sheep at a low work effort and little feed waste. However, the investment in machinery has to be weighed against the improved efficiency.

Every year new premises are built in Sweden, and even if they are made as energy efficient as possible, this will not reduce the energy demands, but the rate of the increase of the energy use will be reduced. One type of facility in Sweden that is a major energy user is public baths, and this makes public baths an interesting facility to study more closely. There are around 500 public baths in Sweden and about 75 % of those can be seen as older baths with large need of renovation, and they all require a high level of energy efficiency measures. To show how the energy demand increase or decrease depending on the changes chosen to be made, the simulation application IDA Indoor Climate and Energy was used. Simulations were made and compared for several cases, with two extreme cases as starting points.

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.

Produktivitet kan inom tillverkande industri användas som ett nyckeltal för mått på effektivitet; enkelt uttryckt hur bra man utnyttjar tillgängliga resurser för att skapa god avkastning. För att öka produktiviteten bör man identifiera och eliminera, alternativt minska risken för störningar i flödet. Bland störningar återfinns bland annat ställtid och justeringar. Genom att reducera tiden för omställning av maskinutrustning ökar tillgänglig produktionstid liksom flexibiliteten i produktsortimentet.Syftet med studien är att identifiera och belysa produktivitetshämmande företeelser och ge förslag till produktivitetshöjande åtgärder för och vid postning såväl för hela flödet vid Chemwood AB i Alvesta. Utöver närmare studie av postningsförfarandet identifierades och analyserades även andra för flödet störande företeelser.Postningsförfarandet vid Chemwood AB kan enbart normeras till den grad där grundläggande moment ingår.Tiden för postning kan reduceras genom enkla åtgärder..

This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees. In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.

The process of value creation is rapidly shifting from a product- and firm-centric view to personalized consumer experience today. Informed, networked, empowered and active consumers are increasingly co-creating value with the firm. The interaction between the firm and the consumer as well as the experience factor plays an increasingly important role in determining the success of a company?s offering. In this study, a special type of co-creating experience is investigated - ?omstartspex? - where the audience is interacting with actors during the play.

Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. The species composition was analysed by ordination analyses, i.e. DCA and CCA.

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

The purpose of this thesis has been to investigate the effect of introducing the qualitystandard ISO 9001:2000 at Metso Paper Service in Sundsvall. The investigation has been focused on implementation of the new method of work, Continuous improvements. The implementation has been studied in a case study with both a qualitative and quantitative method. Continuous Improvements is a way of working focused on continuously increasing the efficiency and having the purpose of achieving the formulated goals. This is often accomplished by the organisation carrying out the changing process to a great extent in small but efficient teams.
