Faktorer som påverkar datakvaliteten hos affärs- och DW-system - En fallstudie från en högteknologisk industri
This thesis aims to examine how the quality of data that is entered into and retrieved from a corporate group's ERP and Data Warehouse systems can be improved. The corporate group has already taken several measures that will improve the quality of data. For instance the corporate group has updated and merged the previous ERP systems into one. At the same time the corporate group adjusted the settings in the updated ERP system, so that it will be harder to register incorrect data in the ERP system. With regards to the processes and routines, the studied department has efficient written routines and processes.
The Digital Content Era
In order to become even more competitive, a partnering with other niche players is essential in achieving a competitive advantage and it enables opportunities for reintermediation. From an intermediate perspective, there are great possibilities for those who become content coordinators to enter the market. By becoming a bundler of services and products, the content coordinators will become the actors that will capture the most profit in the value web. The value creating drivers that have been identified in the business landscape of intermediates concern owning the content or owning the customer relationship. We find the possibilities of an intermediate actor, such as a content coordinator to achieve competitive advantage through strategic fit is subject to the context and the ability of creating more innovative and co-creative distribution systems.
Etableringsstrategier för spannmål : en studie av investeringsbeslut i maskinsystem
In order to produce grain in an economically rational manner numerous decisions have to be made. One of these decisions is what tillage system to use. The cost of the tillage system is a large part of the total cost in grain production. Different tillage systems result in different distribution of fixed costs, operating costs and timeliness costs. The price of the produced grain and cost of inputs also affect the best way to produce grain.
Raalie steering systems
Under ht08 och vt09 har vi gjort ett examensarbete där vi i gruppen utvecklat ett mekaniskt styrsystem för sjukhussängar. Det nya styrsystem ska underlätta det dagliga arbetet för personalen på sjukhusen, då det idag är svårt att kontrollera sängen när man är ensam och knuffar. Men med RaaLie fastmonterad på sängen kan man utföra arbetet själv, och det är mycket lättare att ta sig runt skarpa svängar och trånga passage..
Metod för att mäta förändring av city logistik : - En casestudie på Sandvikens kommun
To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.
BIM i förvaltningsskedet - Nyttan för fastighetsägare
The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.
Informationskrigföring : den nya teknikens hot
The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.
Spolmaskangrepp är ett ökande problem hos värphöns
This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.
Diagnosens betydelse : En kvalitativ undersökning om gränsdragning, kategorisering och fördelning av resurser i det sociala arbetets praktik ? exemplet ADHD
The aim of this study is to examine if and how the diagnosis of ADHD is important for the social practice delimitation to obtain an understanding of how the sorting and categorization of clients affects the distribution of resources. In a qualitative approach, the study is based on eight semi-structured interviews in five different social practices. Young adults diagnosed with ADHD who need society's help and support, constituted our focus in the study. The selection is based on gaining an understanding of how the client process proceeds. The interviews were supplemented with documents, such as legal and internal methodological support.
ANALYS AV FLERBOSTADSHUS : Med inriktning på ytfördelningen över tiden
Currently, there are no clear statistics on how the floor plan and room size in apartment buildings has changed over time since the postwar period. The statistics available is average area per apartment which can be found on Statistics Sweden's website. This report has the aim to increase knowledge about how the Swedish home have changed over time.The questions that the report will answer are:For apartment buildings, how has the living area been distributed since the postwar period?Why has the area distribution changed over time?A survey of the houses built during 1950-2014 was made before questions could be answered. A case study was also made which a total of 90 apartments were analyzed and divided into three eras, the people´s home, the million programme and the neomodernism.

Energy analysis of a fruit drying plant in Adeiso, Ghana
The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit
drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying
process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity.
The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.
Utveckling av Web Service för hantering av öppna autentiseringsnycklar
Utvecklingen går mot alltmer distribuerade IT-system, där ett flertal datorer kommunicerar med varandra. Detta gäller även försvarsmaktens ledningssystem. I dessa öppna och distribuerade system är olika säkerhetsfunktioner kritiska. En av dessa är att kunna verifiera identiteten hos den part som kommunikationen sker med. Detta görs oftast med hjälp av asymmetriska kryptooperationer, där identiteter kan verifieras med hjälp av öppet publicerade autentiseringsnycklar.
