Genom experimentella mätningar har vi tagit fram grafer för luftflöden och förlustfaktorer i spalt mellan vind- och regnskydd i putsade tvåstegstätade fasader. Detta är av betydelse för att veta att inträngande fukt kan torka ut så att konstruktionen inte tar skada. Mätningar gäller för konstruktioner med spaltbildande läkt från Lindab och Europrofil samt även för fallet med helt tom spalt. ResultBy experimental measurements we have developed charts for air flows in the space between the wind- and rain cover in parget two-step sealed facade. This is a presumption to give penetrating moisture a possibility to dry-out and the construction not to take damage. All measurements are based on structures with ventilated air space with profiles from Lindab and Europrofile. The results are then comp

The world has witnessed a remarkable growth over the last 50 years and the urbanisation is becoming a growing problem in many countries. In 1950 29 % of the world’s population lived in urban areas, in 2003 the urban population had grown to 48 %. In order to create a healthy environment in the fast growing cities it is important to have an infrastructure that works. Creating such a city is somethin

The purpose of this study is to show which possibilities the railways in the western part of Småland can offer to the inhabitants and industry within the region. The background is that the passenger traffic is suffering from unprofitability because of bad infrastructure standard, long journey times and low traffic density. The railway between Halmstad and Nässjö was completed 1882, and the branch

Reppe, a starch factory within the concern of Lantmännen is mainly producing starch from wheat but also gets gluten as a product in the process. Currently, the wheat gluten is primarily used to improve the properties of flour for bread-making and as an additive in the baking industry. But there is an interest to explore new uses of the product. To make this possible, the solubility of gluten has t

Vi har i detta examensarbete utfört samtidig mätning av värmeutveckling (hydratationshastigheten) och relativ fuktighet (självuttorkningen) hos hydratiserande cement. Denna studie har gjorts på fyra grundrecept med olika cement där vatteninnehållet har varierats för att få olika självuttorkning. Mätningarna av relativ fuktighet är utförda med RF-sensorer som ger utslag i millivolt som därefter omv

Östra Tommarp is the name of a small village situated outside Simrishamn in eastern Skåne. Bioagro-life is an ongoing project sponsored by the EU. The main ambition is to eliminate carbon dioxide emissions from the process of heatproduction. The project will produce a more environmental friendly alternative to present use of burners with oil as fuel. The heating of the facilities within the villag

We have in our thesis examined energy system for small houses for Skanska Teknik AB. The environment is a current issue in our society and buildings from the past are rarely energy effective, since many houses built during the seventies had heating based on oil or direct electricity. In new buildings it is more and more important to be energy efficient, to meet the demands from our future environm

The independent engineer In the current financial crises, a vacant job is an article in short supply. Good competence and academic titles are no longer a guarantee to receive an employment after examination. These circumstances require a capacity to see opportunities outside the box. When the labor market no longer can offer any jobs, there is two alternatives. Await an opportunity or create an op

Railway detail planning is divided in seven major technical branches; ground works, track, power supply, catenary, signalling, telecommunication and cable-trenching. Technical consultants perform detail planning at the request of a client, usually the Swedish Rail Administration (Banverket). The work results in design and other technical documents. According to common public opinion the quality in

“Comparing Apples & Oranges – A Life Cycle Perspective on the Energy Requirements in Swedish and British Columbian Building Codes” The requirements to decrease the energy use in a building vary in the building codes. “British Columbia Building Code” (BCBC) prescribes a nominal thermal resistance of insulation, while “Boverket’s Building Regulations” (BBR) requires an annual specific energy use

Bodar förbrukar mycket energi, varav en ansenlig del skulle vara möjligt att spara. Det finns regler och lagkrav som måste vara uppfyllda. Specificeringen av hur mycket energi det skulle vara möjligt att spara samt undersökningen av hur väl efterlevda lagarna är, utgör denna rapports syfte. Metoden som har använts är främst litteraturstudier och e-postutväxling med platschefer. Rapporten behandlar

Presence of lactic acid bacteria on a beer brewery The purpose of this thesis is to help a brewery solve a mayor problem regarding the quality of their product. The brewery has for a considerable amount of time had a problem with the presence of lactic acid bacteria in their product, which has caused it to acid long before the expiration date has passed. The root of the problem could be establishe

NCC’s main objective is to reduce their production costs by 5 % each year until 2012. Taking this into consideration, studies have been made to investigate the efficiency on today’s construction sites. There are certainly a considerable number of factors that contribute to today’s inefficiency on the construction sites. Our main objective with this report is to locate these factors, investigate th

Denna rapport har som uppgift att gå igenom hur den nya krypterings och komprimeringsalgoritmen SCAM har utvecklats. Kryptering och komprimering är två vanliga begrepp inom datateknik och det finns många olika typer av algoritmer inom båda områdena. Rapporten går igenom en möjlig kombination av dessa två begrepp till en enda algoritm. Under projektets gång så har två nya algoritmer utvecklats, en

Eftersom det går åt mycket energi för att tillverka asfalt, så är det viktigt att undersöka om det finns möjligheter att minska energiåtgången. Därför har detta examensarbete tillsammans med Peab Asfalt gjorts, för att undersöka möjligheterna till sänkt tillverkningstemperatur. Detta examensarbete syftar till att undersöka om det är möjligt att sänka tillverkningstemperaturen med 30 °C för varmtil

Track switches are vital parts in the railway construction. They meet an important feature when planing and stearing the traffic flow through them to increase capacity. To ensure functionality during winter they have since the 50- century systematically installed switch heating with different technical solutions but with the same objective, to keep the moving parts on the switch free from snow and

Fiberbar manufactures glass-fiber reinforcement that is intended to be used in different types of structures, such as buildings and bridges. In order for the reinforcement to fulfill it’s purpose. It’s requires that the reinforcing and concrete interact under load. Earlier trials have shown that the anchorage between the concrete and glass fiber reinforcement is substandard for Fiberbar AB's p

In the 1960:s the Swedish government approved a decision that led to the construction of about one million households during the years 1965-1975. Today these buildings are both deprived and suffer from high energy consumption. To address these problems individually is very expensive. If it instead is done simultaneously substantial savings can be made. The company AB Helsingborgshem owns and manag
