KL-trä och limträ : hur råvarans kvalité tas tillvara i den färdiga produkten
Detta är en studie som behandlar hur väl kvalitén i trädet tas tillvara för sortimenten limträ och KL-trä. Limträ består av ett antal lameller som limmas samman med fibrerna i längdriktningen medan KL-trä är en krysslimmad skiva som består av en mängd sammansatta lameller. Trä är ett heterogent material som har skilda egenskaper beroende på var och hur det växt. Genom att sätta samman heterogena trälameller vill man skapa en homogenare produkt. Eftersom att produkterna används inom olika områden kan man tänka sig att det går att optimera användandet av råvaran till respektive produkt.
e-infrastruktur som stöd för hemtjänsten
The annual cost of home care services of transport in Falun/Borlänge, is now at 31 million kronor. It is clear from previous research that it is possible to reduce these costs through a restructuring of the existing home-help service. The restructuring aims to have a higher proportion of older people, who are in need of care, to live in special accommodation, in order to reduce transport costs. Therefore there is a need for systems that allow home-help service to plan their operations in such a way that transport is working as efficiently as possible. Through better planning, there are profits to be done.
Smart förpackning för transport av temperaturkänsliga produkter
Vid transport av temperaturkänsliga produkter krävs en förpackning som klarar av att hålla temperaturen inom ett visst intervall så att innehållet inte skadas. Omgivningstemperaturen kan variera mycket under en transport och det är viktigt att förpackning kan kyla passivt utan att påverkas för mycket av omgivningen. Ett typiskt användningsområde för denna typ av förpackningar är inom sjukvård för transport av läkemedel, organ och andra biologiska produkter.Problemet som denna rapport behandlar är att ta fram en sådan förpackning för hingstsperma som skulle kunna skickas med posten. Sperman behövde först kylas ned från rumstemperatur till 5°C under tio timmar innan den skulle hållas vid denna temperatur i ytterligare 24 timmar. För att lösa detta användes en kombination av isolering och fasomvandlingsmaterial vars egenskap att lagra energi gör att en konstant temperatur kan hållas under en längre tid.
Demonstrationsrigg för mätning av vätskors egenskaper
Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.

This report is part of the major thesis carried out at Stoneridge Electronics in Bromma,Stockholm during autumn and winter 2005-2006. The background to the thesis is the trendwithin the automotive industry where color displays have become more common for presentationof information to the driver, a trend that has come to the commercial vehicle market. Thepurpose of the thesis has been to evaluate whether programmable logic, with respect to FPGAtechnology, could be suitable for display control and graphics generation of these more complexcolor displays in automotive environment.Within the scope of the thesis the FPGA technology has been investigated, i.e. whatopportunities and threats there are with aspect to environmental and security requirements. Inaddition, the market of FPGAs and pre-built IP-cores has been investigated.
Tillväxt och potentiell sågtimmerkvalitet i gallringsmogna jämförelseplanteringar med Pinus contorta och P. sylvestris :
The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.
Trafikverket : Kritiska faktorer i projekt inom avdelningen Nationella Projekt
This study has been made on behalf of the Swedish Transport Administration to study the work of the department National Projects. The Swedish construction industry has for many years been characterized by low productivity. By being the largest purchaser of contracts in the industry the Swedish Transport Administration has a unique opportunity to influence the productivity. In order to improve in productivity The Swedish Transport Administration is adopting a new role in which they will order more turnkey projects. In our study, we will focus on how one department within the Swedish Transport Administration, National Projects, can perform successful turnkey projects.To clarify how the department National Projects can perform successful projects, this study identifies critical factors for projects and their links to different phases of the project.
Bemannat vs. Obemannat : En komparativ studie av bemannade och obemannade stridsflygplans nyttjbarhet inom ramen för Counterinsurgency-operationer
Nya typer av krigföring, så som COIN-operationer (Counter insurgency), ställer nya krav på flygstridskrafterna. Utvecklingen av det bemannade stridsflyget har, om man jämför med UAV (Unmanned Aerial Vehicle), trots detta stått relativt stilla. Obemannat stridsflyg har samtidigt utvecklat förmågor som gör funktionen till en värdig konkurrent på det moderna slagfältet. Syftet med denna uppsats är att undersöka huruvida obemannat stridsflyg kan överta det bemannade stridsflygets plats inom ramen för COIN-operationer. Detta avser jag uppnå genom att undersöka hur väl de båda funktionerna svarar uppmot de krav som ställs på ett stridsflygplan i en operation med inslag av COIN.
Några svenska virkesaktörers system för skoglig planering
The purpose of this degree project is to give an overview of the planning system of four Swedish forest companies. The involved companies are ATA TIMBER, SYDVED, BERGS SKOG and VIDA SKOG. The study is based on information from a literature study and by interviews with personals from the four companies.
Each company is described to get a better insight of the companies work and what potential they have. The description of the planning process comes after that. The companies are described separate from each other and will be compared later in this essay.
Skogsägarenas inställning till markberedning i västra Värmland
According to a press release from the Swedish forest agency in May 2014, western Värmland has the worst regenerations of forest result in the whole of Sweden. The scarification frequency is low in the area. AB Hilmer Andersson want´s to know if the private forest owners want to scarify more than is done today. Good regeneration is important for private forest owners so they can have a long term forest management and economics of their forests.
This academic study is done as an opinion poll. The purpose of the study is to see how big the interest of scarification among the private forest owner is.

Från känsla till handling : Empatins betydelse för frivilligas engagemang
Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.
Andningsbesvär under transport : En studie om skillnader och likheter i vitalparametrar och omvårdnadsåtgärder av äldre patienter med andningsbesvär, vid ambulanstransporter med olika transportprioriteter.
Äldre patienter med andningsbesvär är en vanlig patientkategori inom ambulanssjukvården. Är det någon skillnad på patienters vitalparametrar eller givna läkemedel vid ambulanstransporter med prio 1 och prio 2. 43 ambulans och akutjournaler studerades retrospektivt. 24 prio 1 och 19 prio 2. Patienter som transporterats med prio 1 hade signifikant sämre värden på andningfrekvens, puls och kroppstemperatur.
Fiberföstärkning av Limträbalkar
Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.
