Effektivitetsundersokning av medeltida kastmaskiner
Through the ages mankind has developed and tested a cascade of varying weapons ofwar, large and small, and has has striven to push these creations to the limits of theirtime. A grand example of this are the medieval siege engines that have changed shapeseveral times over the centuries. After all this time the eciency of these siege engineswill have reached their peek.
BIM - Tillämpning och effekt i byggprocessens olika skeden
Byggbranschen står inför stora förändringar i framtiden i och med att BIM (Building Information Model/Modelling/Management) successivt introduceras inom området. BIM innebär en förändrad arbetsmetod som kan ge förbättrade möjligheter att minska tidsåtgången och omarbetningar i ett förprojekteringsskede samt skapa ett effektivare projekterings- och produktionsskede med färre fel. BIM är ett relativt nytt sätt att inom byggbranschen bedriva projekt och innebär en förändring för olika skeden inom byggprocessen vilket påverkar inblandade parter.Syftet med denna studie är att ta reda på hur Peab i Kiruna på bästa sätt kan nyttja möjligheterna som finns med BIM samt redogöra för några av de förändringar BIM kan innebära jämfört med nuvarande arbetsmetoder.En teoretisk del beskriver BIM och dess för- och nackdelar inom olika områden samt vilka hinder det finns för arbetsmetoden. Ett resultat baserat på den teoretiska delen förklarar att BIM i dagsläget främst bör nyttjas av Peab i Kiruna i ett anbudsskede, där ett förfrågningsunderlag görs om till en BIM-modell. Detta kan leda till underlättande för företaget att se fel i förfrågningsunderlag samt att utförande av mängdavtagning och kalkylering kan ske på ett enklare sätt.
Samiskt skogsutnyttjande, dimensionsavverkningar och naturvärden : skogshistorisk analys i block 5, Pakko kronopark i Norrbotten
In order to understand the human impact on today?s remaining ?virgin? forest and to develop sensible management strategies for future reserves, it is necessary to know how these forests have developed. This knowledge can be gained by using forest history analysis. here are large areas of forests still untouched by modern forestry in the mountainous region in the county of Norrbotten. These forests are highly interesting study objects from an ecological and historical point of view.
Styrelsen och CSR : En studie om hur en styrelses sammansättning påverkar företags rapportering av CSR
Syfte: Syftet med studien är att undersöka huruvida bolagsstyrning har en påverkan på ett bolags rapportering av CSR på den svenska marknaden. Liknande studier finns utförda i andra länder men det finns ett kunskapsgap i Sverige och förhoppningen är att komma med ett resultat som är mer tillämpbart för svenska förhållanden. Eventuella resultat kan komma till nytta för företag som vill förändra sina CSR policyer.Metod: Vi använder oss av en kvantitativ ansats för att med hjälp av statistiska metoder svara på vår problemformulering. De metoder vi har använt är korrelationsanalys, för att undvika problem med multikollinearitet, och därefter en multipel regressionsanalys för att testa sambandet mellan beroendevariablerna (CSR rapportering) oberoende variablerna (styrelsens sammansättning) och våra kontrollvariabler.Slutsats: Vår slutsats är att en bolagsstyrelses sammansättning påverkar företagets rapportering av CSR. Fler kvinnliga ledamöter i styrelsen leder till en ökad rapportering av både miljömässig och social CSR.
CSR, det har jag aldrig hört talats om! : En studie om anställdas förhållningssätt till CSR
Title: Communicate ? to provide an opportunity Authors: Ida Eriksson & Petra LindbergTutor: Johan Grinbergs, Mälardalen UniversityExaminer: Cecilia LindhSubject: Bachelor's essay, Business AdministrationKeywords: communication, internal communication, channels, communication models, communication theory, information, organizationPurposeThe idea of this study was to describe how ABB Sweden?s internal communication and information appeared in Västerås. The aim is also to see what tools and channels they use to communicate information internally and see how employees perceive them in Västerås.MethodWe have read literature in form of books and articles that discuss theories on the subject communication including internal communication, channels and tools. Interviews were conducted with employees of ABB and were to serve as the basis for our empirical work. A survey by the Communication Center was made in the spring 2010 and was also the basis for our empirical work.ConclusionsThe communication has been increasingly from one-to two-way communication. To get a functioning organization, it is required that the internal communication in the first place will work.
Industrialiserat byggande
The industrialization of construction is increasing in Sweden which leads to higher demands of prefabricated components and cells. But what does the business of construction think of the industrialized business and what can be done in order to decrease faults and errors with these products? Today we have many manufacturers who have different technical solutions which might lead to difficulties when assembling components and cells at the building site. But by trying to make a more opened market, with possibly standardized connections details and improving the communication between the different participants, the prefabricated components and cells can be made and assembled with less errors. This is something that needs to be done in order to establish a more secure business, and especially when working with new companies and methods, when using industrialized products..
Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal
Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.
Examination of mycorrhizal associations of Allanblackia stuhlmannii : a tree under current domestication
Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.

Internal Market Harmonisation and Trade Implications for Non-EU Companies
After the formation of the European Union internal market in 1992, member state specific obstacles and barriers were largely removed. This was especially the case in harmonised industries where standardisation and technical regulation have led to legal certainty. Despite this, a large range of trade regulation continues to remain distortional to trade, in addition to the ongoing tariffs and subsidies. The key trade regulations relate to a number of areas involving technical regulations such as production labelling and the protection of intellectual property rights. Whilst policy makers claim justification based around the need to correct market failure in delivering desired outcomes, the question is whether these regulations are appropriate responses to market failures or if they have simply been imposed in an attempt to protect domestic markets.
Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
BitTorrent i kommersiella system : Identifiering av incitament och användarbeteenden
Companies that sell digital products such as software and movies transfer large amounts of data to its customers. In order to send this amount of data using FTP or HTTP and still maintain a high speed transfer rate it is required that the company have a large number of servers and a huge bandwidth. Servers and bandwidth costs money which means they have great costs on the distribution of their products. In order to reduce distribution costs, P2P technology can be used and the most powerful technology to transmit popular files is called BitTorrent.BitTorrent requires users to share their bandwidth. Nowadays, BitTorrent is frequently used to transfer products that are free of charge; one example is the Linux distribution Ubuntu.
Data och Tv-spel : Data och tv-spels påverkan på ungdomar
The purpose of this study is to investigate in what extension students experience that computer and videogames affect them. I have chosen to focus on the physical, mental and social affect that this activity might bring them. I have also examined how much time the students spends in front of the computer or the videogame and in which social context they play.The method I have chosen to use is a quantitative opinion poll which I used in three classes of the later junior high and I have also conducted five qualitative interviews.The conclusions I have drawn from this investigation are that computer and videogames affects teenagers both physically and mentally. Physically the affects of playing videogames mostly can be derived to the physical inactivity they expose themselves to. The students themselves did not experienced any positive physical affects from their playing.Amongst the mental affects that stood out the most I recognized the social training that online gaming provided and also the intellectual stimulation that certain games offered the player.
Övertoner i elnät vid Skellefteå lasarett : Harmonics in power grids at Skellefteå Hospital
The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.
Småskalig livsmedelsförsörjning av mjölk :
During the last year?s Swedish agriculture have had difficult times, with decreasing
prices and at the same time increasing production costs, which has led to bad
profitability and faith in the future.
The dairies in Sweden have also had a rough time and there have been large
rationalizations during the years. In the beginning of the 20th century there were almost
1700 diaries in the Swedish countryside. There has been a large technical development
during the 20th century resulting in a decrease in diaries to only 46 in the whole country
today. They are owned by 15 diary companies, of which 7 large and dominate on the
market and the rest are small-scale companies.
With this development the confidence and feeling for the diary companies also has
decreased.
