Kan vi inte ha en sån där istället? : om teknisk kravställning på ett fartygsbaserat UAV-system
Detta arbete kretsar kring obemannade luftfartyg, UAV, avsedda att baseras ombord påörlogsfartyg. Regelverk och standarder tillsammans med befintliga fartygs-, helikopter- ochUAV-system utgör ett ramverk inom vilket ett scenario leder fram till grundläggande tekniskakrav för de delsystem som ingår i ett fartygsbaserat UAV-system. Kraven, som är framtagnamed spårbarhet i sjöoperativa förmågor, erfarenheter från den miljö ett luftburet system skaverka i ombord och systemexempel som visar vad som är möjligt att uppnå med dagenstekniknivå, presenteras som ett förslag till värderingskriterier och effektmått med tyngdpunktpå de krav som ställs på luftfartyget (UAV) i sig..
Additivt tillverkat material
SammanfattningDet här projektet behandlar området Additiv Tillverkning (AM) för metalliska material och undersöker om det är lämpligt att använda vid produktion inom flygindustrin. AM är en relativt ny tillverkningsmetod där föremål byggs upp lager för lager direkt ifrån en datormodell. Teknikområdet tillåter i många fall större konstruktionsfriheter som möjliggör tillverkning av mer viktoptimerade och funktionella artiklar. Andra fördelar är materialbesparing och kortare ledtider vilket har ett stort ekonomiskt värde.En omfattande litteraturstudie har gjorts för att utvärdera alla tekniker som finns på marknaden och karakterisera vad som skiljer de olika processerna. Även maskiners prestanda och kvalité på tillverkat material utvärderas, och för varje teknik listas möjligheter och begränsningar.
Fallstudie av innergårdar och entréplan vid Televerket i Farsta : dokumentation, värdering och framtida utveckling
There are few legally protected gardens in Sweden, and those that are protected are mainly from the 17th and 18th centuries. All time periods have the same value and more modern gardens therefore needs to be protected. Evaluating parks is, however, complicated since it do not exist any methods.
One environment from the 1960?s that has not been protected is Televerket in Farsta, Stockholm. The facility has been classified as worthy of preservation by Stockholm City Museum and has received the Kasper Salin Prize.
Ringtrycks påverkan på vägslitage Tunga fordons ringtryck och dess påverkan på vägens underhållsbehov
SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.
DISA-metoden : En undersökning om gruppledarnas bedömningar av genomförandet och av metodens framtidsutsikter
Twice as many women as men suffer from mental ill-health. The negative trend of mental problems among teenagers continues. In certain places in Sweden, 40 per cent of the teenage girls have outspoken symptoms of depression. This is why it is important to observe mental ill-health in a public health perspective. One effect evaluation of the DISA method (Depression In Swedish Adolescents) drew the conclusion that this universal depression preventive method is well working. The DISA method includes cognitive behavioural techniques that change negative pattern of thinking, give practice of communication, strategies of problem solution plus exercises to strengthen the social network.
Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö
The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
Effekten av olika sorters hälsoinformation på efterfrågan på rött och vitt kött.
A pilot-study was used to investigate, types of assistance, assessed needs, outcomes and effects of special-needs assistance given to a subsample of compulsory school pupils in an effort to develop an evaluation strategy for identifying educational impacts of specific special-needs inputs. Preliminary results indicate a tendency for postive outcomes for most pupils in the pilot group (n = 11) but also that many pupils have residual difficulties. Pupils with residual difficulties mostly required special education asssitance with Maths, English or Swedish. More pupils also needed support with behavioral difficulties. More research and an expanding knowledge base is required in order to effectively evaluate outcomes of teacher support. Schools need help in devising different methods of assistance and particularly for pupils with behavioral difficulties..
"Jag blev intresserad av matte" : Ett aktionsforskningsprojekt med formativ bedömning i matematik
This thesis examines the implications of a shorter intensive action research project on the formative assessments key strategies four and five that are activating learners as learning resources for one another and activating learners as owners of their own learning. The research questions were ?How do the pupils experience the formative approach?? ?What didactic consequences does the formative approach mean for the role of the teacher?? and ?How does the formative approach affects the pupils? results on a short term??. The results were that the majority of the pupils liked the approach and that they felt like their efficiency increased. The didactic consequences were that the teacher had to spend more time on evaluation but had more time during the lesson to listen to and discuss with the pupils. The pupils? results were not changed in comparison with the control group..
Fukt i byggnadsmaterial : Hur man förebygger fuktskador vid materialhantering på byggarbetsplatsen
Byggsektorn har fortfarande svårigheter med att hantera fuktproblematiken. Vi har valt att fokusera på hanteringen av material i produktion. Den informationssamling vi utfört ligger till grund för vår analys och slutsats. Vi har intervjuat flera olika entreprenörer från byggbranschen för att ge oss en helhetssyn av fuktsäkerheten ute på byggarbetsplatserna. Studien påvisar att det råder brister både på beställar- och entreprenörssidan. Vi ser att det finns potential för förbättring när det så krävs.
E-handelsrelationer: en fallstudie av hur e-handelsföretag
arbetar med sina relationer till konsumenter
The purpose of this thesis is to examine how e-commerce companies work with their relationships to customers. We have conducted a case study of two companies, Koll and Webbshoppen, both active in the e-commerce industry. Our empirical study has shown that it is important for e-commerce companies to create long-term relationships to their customers, but it can be difficult to create these relationships since the companies have little contact to the users of Internet. To build relationships, e-commerce companies market themselves through different types of media to create awareness. It is also essential to be situated high in search engines.
EmoWheel : En metodutveckling för utvärdering av emotionellt engagemang
This is a study of how emotional engagement can be measured and be taken into account in the development of websites. We believe that emotions become relevant only when viewed in correlation to how users experiencing a webpage. In this study, we developed a tool for use together with user tests where the information about the user's emotional engagement can add new value to the evaluation. The tool allows the user to mark, on the website, his/her emotions and level of engagement represented by colored circles, generating quantiative data on how users feel about the website. The tool is part of a method for evaluating the emotional engagement that we have developed which consists of user testing supported by the tool and accompanied by interviews..
Pelletskvalitet : Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro
Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.
Viskningar från en grav. Att se ett förhistoriskt samhälle via gravmaterialet
Since the down of archaeology much of the resurges has focused on graves andgrave materials. This essay is an attempt to interpret a grave material to the society of the living, to investigate what a megalithic grave material can tell us about the society that made them and the people that were buried in them. The study is focused upon two megalithic graves in Löderup; Ramshög and Carlshög. A study of the bone materiel, building construction and building material at Ramshög and Carlshög is done and then compared with different theories that are made of Ramshög and Carlshög and of other megalithic graves. By studying different theories of megalithic graves and comparing these with Ramshög and Carlshög I have tried to evaluate which ones that are relevant in this case.The megalithic graves primarily shows some kind of change, in society or in their way of looking at the dead or the life after this.
Torkat bioavfall som jordförbättringsmedel
The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.
En studie av normerna kring fildelning och piratkopiering
In this paper I have focused on the underlying reasons for people and piracy. The paper starts with a presentation of the Swedish laws of copyright as they are constituted today and the new law that is supposedly being ordained the 1st of July, 2005, a brief summary of what its effects will be for the people, according to the authorities and the critisism that has developed around it from the net-pirats. Then follows a definition of the expression "norms" and what it means here in my paper.Now comes a presentation of the research I have been doing, in the form of a survey concerning why and how often people download copyrighted material from the net, and if they have ever sold any pirated copies to more than selfprice and, if so, to whom. The presentations shows that the majority of the people that are downloading copyrighted material from the Internet is doing it for the own personal use and not to make any money out of selling the material on, since most people consider it unfair to charge for something that they have got for free.The survey also shows that many of those who download copyrighted material also upload it because it gives them a satisfactory feeling of giving something in order to get something. The survey also shows that although most of the people taking the survey knows what the new law means it has not affected them in anyway.
