The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå.                               The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

Denna studie syftade till att ta fram ett ramverk för utveckling av API:er för tjänsteorienteradearkitekturer. Studien tar sin utgångspunkt i forskningsprojektet e-Me (utvecklingenav en integrationsplattform för att underlätta studenters vardag) samt en benchmarking avde i nuläget mest använda API:erna på webben. Studien har fem faser: En litteraturstudie,en benchmarking, en kvalitativ genererande intervjustudie, en teoribildande fas (framtagningav ramverket), samt en kvalitativ validerande studie. Litteraturstudien tar upp sådanafenomen som utvecklingsmetoder, systemarkitekturer (bland annat SOA) samt metautveckling.Denna studie låg till grund för den första intervjustudien, som i sin tur låg tillgrund för benchmarkingen. Resultatet av dessa två studier bildade tillsammans en grundför ramverket SOAPIF (Service-Oriented Application Programming Interface Framework),som till en början innehöll fyra olika faser: Conceptualization, där man försökerbilda sig en uppfattning om vad API:et skall exponera; Definition, där man försöker definieraett kontrakt för API:et; Testing & Implementation som tar sin utgångspunkt i testerför att implementera API:et; samt Delivery, som är den fas där API:et skall levereras.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

Throughout many years there have been discussions within the European Union (EU) regarding harmonization and improvement of accounting rules for companies with listed shares or other securities. The ambition exists to adopt, the within the union applied accounting standards, to those applied globally. These discussions lead the year 2002 to adoption by the council and parliament of international accounting standards (IFRS). The ordinance meant that all listed European companies have to adopt international accounting standards, accepted for application within the EU, for their consolidated accounts.During July 2003 the Swedish Government Official Reports issued a report (SOU 2003:71) stating, among other things, the differences and oppositions of implementing IFRS on a corporate level in Sweden, since corporate disclosure is regulated in Swedish law by Bokföringslagen (BFL) and Årsredovisningslagen (ÅRL). One of the main obstacles for the full implementation of IFRS is that a company?s annual report underlies the governmental taxation and an implementation of IFRS would affect this balance.

Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting.  Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

In the last decades the Swedish labor market has been characterized by a stereotype perception on women?s role and position on the market. The perception speaks of the characteristics of female leadership as being less qualified causing the gaps between the two genders to transform into a gender segregated society. The historically slow progress has limited the career opportunities for women to reach top management. However the increasing discussions during the 21st century on how to reduce the gender differences in the labor market has made it more acceptable with women on higher positions.

During the last couple of years many sectors and markets have had an increase in the competitive situation, this has meant that being cost effective have become more essential if organizations want to stay in business and be competitive. Thus, one crucial issue has become how to utilize the resources already available within the organization. Organizations can thoroughly plan and control personnel resources in order to become more efficient. But to become more cost effective also means taking into consideration several key figures, productivity being one of the more important figures.Onninen, a wholesaler which has one of its two central warehouses in Örebro has experienced this issue, i.e. an increase in competitive situation in their market.

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.
