Det finns två stationer på Boxholm Stål AB med produktionssågar. Den ena är en bandsåg och två fasmaskiner med hanteringsutrustning för transport mellan såg och fasar samt en automatisk buntmaskin. Fasarna på den stationen är utslitna och håller inte de toleranser som Boxholm Stål AB har på sina produkter. En önskan att kunna planfräsa ändarna har också tillkommit vilket utrustningen i dagsläget inte klarar av. Det innebär att fasarna ska bytas ut.

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.

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.

Denna rapport handlar om en användbarhetsutvärdering av synthesizern OP-1, utvecklad av företaget Teenage Engineering. Studien är kvalitativ och undersöker bara den omedelbara användarupplevelsen av produkten. Rapporten baseras på resultat från ett antal användbarhetstester, utförda på företaget i fråga. Användbarhetstesterna avser att undersöka hur en användare kan förstå hur OP-1:s kan användas och hur de kan förstår dess olika lägen och vidare på vilket sätt detta påverkar den initiala användarupplevelsen.Totalt nio av fjorton tillfrågade personer har ingått i användbarhetstesterna. Urvalsgruppen bestod av personer med tidigare, dock varierande mängd, erfarenhet av synthesizers.

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.

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.

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.

The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement.The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers? attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden.The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole.

The purpose of the study was to identify and analyse the implications of client virtualisation in company environments. The study chose to focus on the aspects of the current hardware, license management, application management, maintenance work and the implications virtualization would have on these. The work in the study was chosen to limit itself to a Windows environment.The background to the study was due to a growing need to be more flexible and mobile in company environments and in collaboration with the University of Jönköping a problem description and the framing of questions was defined. The essay tooka qualitative initiative to comprehend the complexity of the problem at hand. The empirical data was collected from interviews, literature studies and laboratory work testing applications.
