Konceptuell design och utveckling av hybridfordon

This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

Utfackningsväggar ur lufttäthets- och fuktsäkerhetsperspektiv : En jämförelse mellan platsbyggda och prefabriceradeutfackningsväggar

The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.

Ett aktivt beslut att renovera passivt : En ekonomisk jämförelse vid upprustning av miljonprogrammetsflerbostadshus

As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

Det uppätna monopolet : Initiativ, inflytande och resurser vid planeringen av kvarteret Druvan genom projektet Mitt I City

The purpose of this essay is to examine if the municipality has a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project.In Karlstad there is now (2006) a large building project in form of a shopping mall. This project is in its final stage of completion and offers me a suitable case to examine. To undertake the purpose of the essay, the following research question is formulated:Do the municipality have a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project as the Mitt I City project?In an attempt to examine the project and the planning process, three themes are applied. The first theme derives from the hypothesis that the part that initiate the process gets the upper hand as future discussions are taking place in relation to the original ideas.

vindkraftens påverkan på elkvaliten

This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

Fjärrvärme - ny lokalisering av kraftvärme i Enköping

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Att låta tusen blommor blomma. - Lärares syn på relationens betydelse för elever med koncentrationssvårigheter.

The aim of this bachelor's thesis is to investigate how teachers view the way they build their relationships towards students, both in general and, more specifically, towards those students with some type of attention deficits. The focus of this thesis has been on how great an importance teachers place on this relationship. Especially when it comes to working with students with attention deficits. We also want to know to which extent this relational perspective is rooted in teachers' practice. The theoretical basis of this study is the relational perspective formulated by Aspelin and Persson (2011).

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

En skattemyndighet : Balans mellan maktutövning och relationsbyggande

Background: Power by force and threats used to be the common way to collect taxes, but this procedure is today completely different. It?s now more about building a mutual relationship and with help of laws and controls steer citizens and companies to pay the tax they owe. Thus the way to collect taxes have changed over the years, the collecting of taxes aren?t a popular task to do.

The thinning Quotient - a relevant description of thinning?

Det finns en rad satt att beskriva gallringsformen. Ofta används begreppet gallringskvot i dessa sammanhang utan att närmare ange vilken metod eller definition som använts for att beräkna den. Detta kan lätt leda till att missuppfattningar uppstår. Denna studie belyser olika definitioners känslighet for bland annat beståndsstruktur, gallringsform och stickvägsavstånd. Studien innehåller dessutom en jämforelse mellan olika metoder att mäta och uppskatta gallringskvoten i ett bestånd.

Framtagande av riktlinjer för arbetsplatsbesök enligt nya Plan- och bygglagen

A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.

Kv. Draken : En studie i kostnadseffektivt byggande

Den bostadspolitik som förts de senaste två decennierna har gett oss en alltmer segregerad stadskärna i Stockholm. Byggsubventionernas avveckling på 90-talet har lett till en historiskt låg byggtakt och ett byggande som ensidigt riktat sig till resursstarka grupper i samhället.Parallellt med detta har stora delar av hyresbeståndet ombildats till bostadsrätter vilket medfört att många relativt billiga hyreslägenheter i äldre fastigheter har försvunnit ur beståndet. Dessa är svåra att ersätta med nyproduktion, då dessa är dyrare.Kärnproblemet är förstås att det är dyrt att bygga hus och om man antar att den nuvarande bostadspolitiken består är det ytterst angeläget att utveckla kostnadseffektiva byggmetoder för att möjliggöra lägenheter med överkomliga hyror som kan bidra till att motverka boendesegregationen på sikt.Vårt förslag består av ett bostadshus i Stadshagen. Fastigheten är indelad i två byggnadskroppar som länkas samman via ett system av loftgångar kopplade till ett trapphus. Husen är uppbyggda av volymelement som staplats på en platsgjuten sockel.
