At the bottom of the screw conveyer and the inlet feeder there is a bearing that keep the parts together. However the lubrication of the bearing must be made manually.

Hur fyra gymnasielärare möter ideal och verklighet : En jämförelse mellan främmandespråksundervisning i Sverige och Australien

This degree project shows how four language teachers teach foreign languages with focus oncommunicative competence, and how their vision of teaching correspond to their reality in the classroom. How do they motivate the students in class and are the conditions good enough tohelp the teachers reach the national goals? A teacher?s vision is formed by his or her education and experiences. However, there are a number of factors which can help or hinder a teacher to reach his or her ideal teaching. Among these factors are the curriculum, the preknowledgeof the students and available technical resources.

Buntning av grot med lastbilsmonterad utrustning :

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.

Energideklarationer - Marknad och Kundkytta

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Alternativa drivmedel i den svenska vägtrafiken år 2030 : En utvärdering av den svenska regeringens målbilder

The Swedish government has set up the overall goal that no net emissions of greenhouse gases can occur after 2050. A sub-target has been developed for road transports which states that the use of fossil fuels must be reduced with 80% to 2030 in order to be completely abolished to 2050. A public inquiry mapping how this can be achieved was handed in to the government late in 2013. The use of alternative fuels for road transport, both biofuels and electricity, is expected to give the biggest contribution to the reduction of the use of fossil fuels. The inquiry sets up a number of goals for how much the use of alternative fuels must increase to 2030 in order to reach the overall goal and which instruments that are needed in order to do so.The aim of this thesis is to evaluate how these goals can be reached and what the most likely obstacles that may hinder the reaching of these goals may be.

Emballage för väggelement i trä : Paketering, hantering, lager och transport

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

Sociala hänsyn vid offentlig upphandling : En jämförelse mellan det klassiska direktivet och det reviderade klassiska direktivet

The first aim of this study is to examine what the differences are between the Classic directive (directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts) and the Revised Classic directive (directive 2014/24/EU of the European Parliament and of the council of 26 February 2014 on public procurement and repealing Directive 2004/18/EC) when it comes to social considerations in public procurement. The second aim is to examine if the revision of the directive has solved the prior existing problems regarding social considerations in public procurement. In this paper a traditional European legal method is used. The examinations show a number of things, including the Revised Classic directive involving codification of case law, references to other sources of law and some clarified rules as well as new provisions. The regulations regarding reserved contracts, technical specifications, and selection criterion are satisfied in the Revised Classic directive.

HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder

On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.

Kampen för ökad tillgänglighet : - om enskilda aktörer, policynätverk och förhandlingsarenor i utarbetandet av EU:s bussdirektiv

The Motor Group of the European Council was commissioned in the autumn of 1997 to prepare a proposal for a new European Bus and Coach Directive. In the beginning, most of the Member States did not have the accessibility requirements as their main concern; still a smaller network with actors from the National delegations from Britain, Germany and Sweden would influence the other National delegations in the Council group to finally agree to retain the requirement of accessibility of the Directive. Within the EU decision process, the European Disability movement acted as a strong player during the whole negotiation process using the proposal to a new Bus and Coach Directive as a tool to influence key actors to go towards a Directive with a strong approach for accessibility.Policy Transfer and Policy Transfer Network are used as analytical tools to understand and structure the transfer of the question of accessibility during the negotiation process. Actors understanding how the bureaucratic process works within the EU decision system have a chance to contributing for the changes in the directions they wishes for within a range of policy areas. The principal aim of the Directive was to guarantee the safety of passengers and to provide technical prescription in particular to wheelchair users.

Utveckling av nytt koncept för positioneringsslid

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

Förstudie -  Nya koncept för ett effektivt flöde

Examensarbetet har genomförts på den produktionstekniska avdelningen på Volvo Construction Equipment i Hallsberg.Syftet varatt ta fram ett nytt koncept för hyttsvetsproduktionen på fabriken;hur produktionsprocessen skulle kunna se ut i framtiden. Man vill göra flödet i linan mer effektivt med avseende på kvalitet, flexibilitet samt eliminera tidsslöseri som idag är ett problem.När fabriken påbörjade sin produktionproducerade man två olika varianter av hyttertill anläggningsmaskiner, idag har man ökat produktionen till fyra varianter. I takt med att varianter samt orderingång ökat har man byggt på befintlig produktionslina istället för att utveckla en ny, anpassadlinafördet nya läget. Resultatet har blivit att maxkapaciteten är nådd och linan klarar inte att hantera en planerad produktionsökning.En grundlig analys av hyttsvetsprocessen, innehållande intervjuer med bland andra platschef, teknisk chef och flera tekniker genfördes för att få förståelse för processen. Övrig information såsom effektivitetsmätningar på utrustning, värdeflödesanalyser och avvikelserapportering har funnits tillgängligt och legat till grund för arbetet.
