The pre study will contain different cost proposals for the automation of selected process and serve as a basis for procurement of the equipment.The pre study has resulted in some proposed solutions to the various steps required to automate Performance Sk8 ?s production.

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Quality was earlier only an issue for the company?s quality departments but today is the entire organization involved in quality- and improvements work. With the customers in focus, both external and internal, quality and improvement work should be integrated in the daily activities. The management shall state goals and visions together with a policy. Through participation the correct requirements for a successful work are created.With SPC, statistics process control, there is an opportunity to perceive variations in the process and with the correct tools make it stable.

The agriculture is today in a development that leads to bigger and bigger units in the primary production. To be able to follow this development many companies chooses to cooperate in different ways. The most radical change is when farmers fuses with other farmers and merge into to a big collectively owned operation firm. The reason behind this idea is that the firms achieve the big companies advantages by being complement to each other. The purpose of this essay is to make an economic analysis of two crop production companies who works together in an operation firm.

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.

Den ökade förändringstakten i samhället på grund av ny teknik, internationalisering och att samhället blivit alltmer mångkulturellt bidrar till att större krav ställs på företag att hela tiden förbättra sin verksamhet. Akzo Nobel Surface Chemistry, Production Surfactants i Stenungsund, har huvudsakligen sina kunder och konkurrenter runt om i Europa. Då Sverige ligger i utkanten av detta område tar det omkring en leveransdag längre tid för Production Surfactants att leverera sina produkter i jämförelse med företagets konkurrenter. Detta medför att Production Surfactants behöver kompensera denna längre leveranstid genom exempelvis högre produktkvalitet, större flexibilitet eller lägre priser för att ha möjlighet att tävla på marknaden. För att uppnå detta behöver Production Surfactants utveckla och systematisera sitt förbättringsarbete.

Relationships and trust between humans create the psychosocial working environment. This is a basic human activity and is communicated in a continually ongoing process. Conciseness about the value of trust and social capital motivates the need for work, with threats to communication, being conflicts and noise. This can create greater trust in the workplace as a whole, as well in the working team. Scientists are increasingly interested in these social relations in the working environment; there are profits, both for production and in terms of individuals2019 well being, in shifting the focus away from a purely production-oriented, economic perspective.

För att ett företag ska kunna hålla sig flytande på marknaden idag krävs de att de har hundra procent koll på vad som sker i deras fabriker och att de strävar efter en mer hållbar tillverkningsprocess. Att försäkra konsumenterna om att fabrikerna inte använder sig av barnarbete eller dåliga arbetsförhållanden räcker inte längre utan det krävs en bredare kunskap inom miljö och hållbar utveckling för att den trogna kunden ska stanna. Syftet med denna rapport är att kontrollera det nyuppstartade företaget DENIM IS DEAD?s produktion och utvärdera om hur man kan förädla de olika processtegen samt skapa transparens gentemot kund.Metoden som arbetet utformades efter var genom en fallstudie som är baserad på en mestadels deduktiv metod men med inslag av induktiv metod. Där grunden lades genom en utförlig faktainsamling för att i rapportens senare del kunna analysera de hypoteser och problemformuleringar som ställts.Målet med rapporten var att ta fram en metod eller produkt som ska underlätta kommunikationen med DENIM IS DEAD?s kund.

This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

More efficient energy consumption is essential to secure a sustainable future, not least within the building and real estate sector which answers for approximately 40 % of the EU countries total energy consumption. One part of EU: s work to reduce the energy consumption is the directive on energy performance of buildings which among other things have lead to stricter demands on energy performance in new and renovated buildings.One of the difficulties with making buildings more energy effective is that it often demands big investments and although it results in lower operating costs the extent of these savings and therefore also the repayment time can be difficult to decide beforehand. To make it interesting for property owners and also tenants to invest in energy efficient buildings powerful incentives are needed. Favorable loans to energy efficiency projects are one example of governmental instruments that have been tested in other European countries with good results.Reduced operating costs appear to be the main incentive for property owners to make their buildings more energy efficient. The best result of an energy efficiency project is usually achieved by cooperation between property owners and tenants but in order to make that interesting it is important that both parts can profit from the savings.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.
