Lagerhantering i framtiden på Aero Materiel AB

In recent years, increasing emphasis has been placed on streamlining the supply chain. Keeping inventory and warehouses is considered to be a waste of resources. It is however difficult to completely eliminate the need for inventory and warehouses in a supply chain. The purpose of warehousing is to provide a service for the customer. By keeping what the customer demands in inventory it is possible to make a quick delivery when a need arises.

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.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

Utvärdering av viabilitet hos selekterad hingstsperma med hjälp av fluorometri :

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

Evaluation of Lactobacillus reuteri DSM17938 as starter in cheese production

The probiotic bacteria Lactobacillus reuteri DSM17938 was evaluated as a starter culture in cheese production, with the intention to produce a new interesting product within the functional food market. Growth and acidification rate in milk subjected to different heat treatments, as well as supplementation with growth promoting factors or support cultures was measured during controlled fermentations. The results showed that the weak proteolytic activity of L. reuteri could be compensated for by supplementation with 1% casamino acids or 5% MRS broth. Furthermore, a decrease in growth and acidification rate could be seen when using yoghurt culture or Lactobacillus delbrueckii as adjunct cultures.

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..

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.

Pelletering av tallspån : grundläggande studier

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

3D-byggnadsmodeller utifrån takkonstruktioner : Lagring, hantering och bearbetning

A growing number of cities and municipalities in Sweden begin to work with city models in 3D. For the most part the models are used for visualizations of ongoing planning processes, but also for the analysis of noise, shadow studies and environmental disaster simulations.Gothenburg continues to develop the use of 3D maps in municipal operations and is demanding a way to create building elements (walls), which generates in 3D buildings, from roof constructions that are mapped from the primary map. A method has been investigated in the present study. The results are then presented as a 3D model of buildings, along with a terrain map that will facilitate the localization of the area. The created 3D buildings are then compared with roof-data from the primary map to see how well they harmonize with each other.

Systemen med rätt inställning - En studie om whistleblowingsystem i Sverige

In order to counteract and to discover unethical actions within an organisation, a growing number of Swedish companies implement a so-called whistleblowing system. The purpose of our essay is to study the mindset of companies and further analyse how this mindset affects the design and quality of companies' whistleblowing systems. To do this, we have used a qualitative approach by interviewing different Swedish companies about their mindsets and systems. The study determines that there seemingly are three different categories of systems of varying quality. In this study we have chosen to call them "internal system", "external system" and "combined system".

Gulliver Simulation - En systemarkitektur f or n atverkssimulering av

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.
