Förbättrad resistansmätning för grova aluminiumledare
The goal with this master thesis has been to evaluate and to examine the stationary resistance bridge. The resistance bridge uses a 4-point measuring to determinate the resistance, which is used in the manufacturing of the conductor. It is then used when the resistance is to be decided for coarser aluminium conductors. A conductor has to fulfil certain demands to be able to move forward in the process. One of these demands is the resistance in ohm/km, which has demands that the measure values of the resistance bridge are as true and precise as possible.
Annonsplacering : Hur placeringen av annonser i artiklar kan optimeras för högre Click Through Rate
The web as an arena for news reporting and information sharing to consumers has grown for many years in the expense of the traditional newspapers. The revenue stream has however not followed the same transformation which has led to a remarkably lower profit when news and articles are distributed through the web. Banner advertising is a method that is commonly used by online magazines to generate profit where advertisers pay to expose their message. One method to measure banner ads effectivity, and indirectly, what the advertiser would pay, is through Click-Through Rate (CTR), how many clicks a banner ad receives in relation to the amount of banner views. One of the variables that play an important role in the banner ad effectivity is the placement of the banner ad.
Arbetsminneskapacitet: relation till verbalt flöde och indirekt minne för inhiberat material
Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.
En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
Förbättrad resistansmätning för grova aluminiumledare
The goal with this master thesis has been to evaluate and to examine the
stationary resistance bridge. The resistance bridge uses a 4-point measuring to
determinate the resistance, which is used in the manufacturing of the
conductor. It is then used when the resistance is to be decided for coarser
aluminium conductors. A conductor has to fulfil certain demands to be able to
move forward in the process. One of these demands is the resistance in ohm/km,
which has demands that the measure values of the resistance bridge are as true
and precise as possible.
The stationary resistance bridge had been examined through various kinds of
measurements to be able to see how stable the system is and how to obtain a
measure value as optimized as possible.
Totalresultatet ur ett annat perspektiv -En studie om Latour
Purpose Based on the new comprehensive income due to changes in IAS 1, the authors aim to describe how a listed corporate accounting is affected by IAS 1 and the new income statement.Methodology This study uses an inductive approach with a combination of qualitative and quantitative data, using financial rapports from the investment company Latour. This case study is based on Latour?s all published financial statements under the period 2008 to 2012.Result The study resulted in different observations of Latour's operational and financial performance, share price trends as well as ratios. The study's authors can see that Latour's net income and comprehensive income differ due to changes in IAS 1. They can also observe the effect of clean surplus in Latour?s income statement.
Klassificering och värdering av finansiella instrument : Ett tillförlitlighetsperspektiv
During the financial crisis voices were raised towards the regulatory framework IAS 39 recognition and measurement of financial instruments and pointed out that it was inadequate. The complexity of the framework contributed to the fact that it was difficult to apply. IASB accelerated the modeling of the new to be regulatory framework IFRS 9. In this study we will focus on the reliability of accounting information, which is an important aspect from the stakeholder?s point of view, for example, to be able to make the best decisions the accounting information should be proper.
Tillförlitlighet hos trafikolycksklassificering
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Pelletskvalitet : Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro
Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.
Simulering av valkar i pappersrullar : och analys av de slappa stråk som uppkommer
A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy.
Magasin för lagring av vatten och växtnäring
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Morgondagens arkiv : Om arkivhantering i framtiden
The aim of this study has been to create a future scenario of what archiving might look like in the future. The main theory used in the study comes from future studies, but also a theory about the social impact of technology on work were used. The questions that were analysed were about the tasks of the archivist, the appearance of the archival institution, collaboration with other LAM institutions, knowledge requirements for the archivist and the amount of archivist positions. The method used in the study was scenario writing, which derives from future studies. The source material consisted among other things of regulations and laws related to archiving together with some archival manuals.The tasks of the future archivist will probably consist of the same tasks as those of present archivists who work with digital archiving, even though archivists probably forever also will have to work a little with paper records.The future archival institution will probably retain its paper records and keep its digital records on digital storage media.
Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn
This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.
Brikettillverkning på gårdsnivå :
In my work I have chosen to examine the profitability for small scale production of hemp briquettes. My study also includes a review of which briquette technique that is the most common one among small scale producers. The reason that I have chosen this subject is because of the discussions about climate and energy that we face almost every day. I also think the subject is extra interesting in these days when the grain prizes are at a historic high level.
In order for me to achieve a reliable report, a hemp and briquette producer has given me the actual data from his farm. In that way I have been able to make my calculations from a concrete perspective.
