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.

Stress test methods : a potential approach to hurry up shelf-life tests on oat products

According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

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.

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.

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.

Automatisk viktkontroll av glascontainer

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

Undervattensvågbrytare - En modellstudie

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.

Vintervegetation genom ljus : om hur man med belysning kan framhäva avlövad vegetation i offentlig stadsmiljö

Use of lighting is crucial to make public urban places available during dark hours. Landscape architects participate in planning of lighting, but during our education there is very little taught on the subject. Through this study we approach the subject of lighting by looking into lighting methods for urban plant materials during winter. In this thesis we look into ways to emphasize the visible characters and experiences of urban plants during winter season using light. Target audience are landscape architect students and landscape architects without knowledge of lighting. The part of the thesis that describe basic conditions for, and visual characters of plants can be useful to lighting designers without knowledge in this subject. Working methods used were the following: ? Pre-study about light and lighting techniques through literature and dialogues. ? Compiling important visual winter plant characters through photography and literature. ? Outdoor light experiments with plants.

Klimatförändringar och dess effekter på ogräsfloran i Sverige :

Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.

Effekten av klimatförändringar påkontrollbehovet av åkerogräs

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

Dokumentation av en experimentell biogasanläggning

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

Kultur i förändring : En vidgad syn på kultursektorn och dess roll för samhället

How can you do a right measurement of culture as well as with other social sectors and with what can culture contribute when it comes to a town´s development? We found out that in Linköping the regional federation Ostsam recently (2005) started mapping the region's creative centers in order to look into the spreading of the culture in the county, and then use the uniqueness of the culture as an advantage in society- planning contexts. The reason was that both municipal - and State directions detected that the culture has a broader importance when it comes to building up society and infrastructure than earlier considered. This is called Cultural planning and is the foundation- method that Östsam used when working with their new projekt The creative sector. The outcome of the Östsam study resulted in an exciting study basis to work further on with and to examine through own demarcations and directions.This research manages the matter of the creative sector as an extension to the cultural sector.
