Framtagandet av ett företags visuella produktidentitet
Aqeri has since the past year a new profile with name and logotype, which has createda need for an updated visual product identity. The company is a leading developer,producer and distributer of IT products suitable for extreme environments in industry,defense and vehicles. This new profile with the different segments has together with aproduct identity from two companies resulted in that they have no clear designidentity on their products. From this background the aim of this research is todetermine how a development of a design identity is done to implement it to Aqeri.The design identity can be defined as a product?s identity visualized through its formor appearance which defines what the product is.
Naturlig förekomst av arsenik och avskiljning av arsenik från grundvatten : test av olika filtertekniker avsedda för enskilda brunnar
During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003.
Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.
Solmodul jord- och bergvärmepump
An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.
Konsekvenser för äggproducenter efter förändring i djurskyddslagen avseende inhysning av värphöns :
The avowed aim in this project was to see how the Swedish egg production is today. My first question was if the Swedish egg producers egg production turn a profit. I have done five after calculation at five different egg producers with different systems from case to case. The difference has been the living system, the fodder and the egg price.
They made a report in Uppsala, Sweden (Hoffman & Andersson, 1996), where the look forward to a Swedish cage ban and made calculations after that coming ban. After that they lift the Swedish ban of cages and the egg producers could invest in new cages who called the decorated cage.
Automatisk trafiksäkerhetskontroll
Hela projektet ATK startade 1999 i och med att regeringen skrev sitt 11 punkts program för att få ett snabbt resultat på de farligaste vägsträckorna i Sverige. Hela projekt bygger från början på Nollvisionen som syftar till att få ner antalet skadade och döda i trafiken. Huvudsyftet är inte att bötfälla folk som kör för fort utan ett sätt att få ner medelhastigheten på farliga vägar där det förekommit mycket olyckor med svår utgång. ATK är ett automatiskt system som med hjälp av radar och digitalkamera fotograferar hastighetsöverträdelser och sedan rapporteras dessa genom kontorsförelägganden. Statistik visar att under projektets gång har medelhastigheten sjunkit samt antalet svårt skadade och antalet döda har minskat, samtidigt som lindriga skadade givetvis ökar.
Komponentuppdelning av elnätetpå lokalnivå
Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.
Trädgårdar på tak- och gårdsbjälklag :
The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens.
Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions.
The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.
Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth.
Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.
User Interface Design for Analysis of Sensor Systems
In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user interface for the C2SR-system was performed.
Vem är det framför skärmen? : En fördjupad textanalys om hur svenska politiker konstruerar jag-bilder på Twitter.
The trend of social media is a global hit and now both individuals, businesses, celebrities and politicianshave their own social media pages, which means that the visibility increases and focus lies on what'swritten and published by the person. Mediated communication are everywhere around us and affects theway we communicate with each other and also the way we look at ourselves and most importantly how weportray ourselves. The individual's perspective has become a relevant issue with the rapid moderndevelopment. One's cultural identity can be seen as a life-long project.The purpose of this paper is to do an in-depth text analysis to examine how Swedish politicians constituteand construct identities, with a focus on "the self" and the "mediatization self" on the micro-blog Twitter.The theoretical ground for this study is from a discourse analysis point of view that focus on ?the self? andthe ?meditization self?.
Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
Objektdetektering i SAR- och IR-bilder
This report treats detection in IR-pictures taken from airplanes over the ground. The detection is divided in two parts. First there is a detection with filterkernels with the task to point on targets and objects that look like targets. The second part is a discriminator that demands more calculations and has the task to sort out the false alarms from the discriminator. Both the detector and the discriminator contain thresholds thats been trained from trainingsets of data.
Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island
This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.
11 september under elva år : En kvantitativ studie av Dagens Nyheters rapportering om 11-septemberattackerna i USA på årsdagarna 2001-2011
Syftet med denna uppsats är att undersöka om nyhetsvärderingen har ändrats under åren 2001-2011 i Dagens Nyheters nyhetsrapportering om attackerna mot USA den 11 september 2001. Detta har vi gjort genom att studera bevakningen av årsdagarna för terrordåden. Dagens Nyheter valdes eftersom tidningen har en tillräckligt stor redaktion och tillräckligt med resurser för att täcka internationella händelser. Vår teoretiska ram utgörs av tre nyhetsvärderingsteorier. Med dessa som utgångspunkt utformade vi variabler och gjorde en kvantitativ innehållsanalys.
Utvärdering av näringsstatus inför återskapande av kalkkärr vid Hagebyhöga, Östergötland
Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.
