Undersökning av avfallshanteringssystem : För ett nyexploaterat område i Ekhagen, Jönköping
Outside of many Swedish households today, you will find a typical green wastecontainer. This container has not changed since its introduction, despitecomplaints about foul-smelling and its impractical system. Even if the system usedtoday, still is the most optimal choice, there is a lot of newly developedalternatives out there.Its purpose is to get a broader perspective on how a waste management systemcan be developed into a working, land efficiently and aesthetically pleasing systemof humans and the environment in a small residential area.The authors treat the residential area of Jära, Ekhagen, in Jönköping, which ismanaged by JM AB as a problem area in regards to waste management.The issues raised by the authors are the different waste management systems usedin the corresponding areas of the world, how to apply technical andenvironmental as well as the waste management facilities from financial aspects.In the process, the methods used were literature reviews, case studies and aninterview. The case study was done through a modeling of waste managementsystems in the area Jära and an interview was conducted with the company Envacworking with vacuum systems. Studies have been made by different systems n theareas around the world.The results show that using directives and guidance will reduce the environmentalimpact done without replacing the traditional system.
Optimering av reducerad bearbetning : högre skörd till lägre kostnad
Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.
Förslitning av fräsverktyg
Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.
RTLS - real time location systems : an inventory study for agriculture applications and requirements
The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture.
In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.
Genotype by environment interactions of claw health in Swedish dairy cattle in tie stalls and loose-housing
Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.
Jag är ny här - får jag vara med? : En studie av nyanlända elevers sociala integration i skolan
The aim of the study was to evaluate the social integration amongst newly arrived students in the two different school systems Sweden welcomes them into. The first school system takes in newly arrived students into preparation classes whilst the other integrates the students directly into ordinary classrooms. The examination is based on qualitative observations in the classroom, canteen, and playground, and interviews with teachers and a select few students from each school system.The result of the study showed that newly arrived students in ordinary classes are socially integrated more into the school than the newly arrived students that are welcomed into a preparation class. Newly arrived students are offered a larger chance of being integrated into the school environment if they are introduced directly into an ordinary class. In preparation classes, social integration is narrowed down to between the classmates.

Utveckling av ett fällbord för offentlig miljö
Denna rapport omfattar ett examensarbete på 22,5 poäng. Examensarbetet har utförts inom ämnet integrerad produktutveckling vid Högskolan i Skövde tillsammans med Jai Designpartner AB. Målet med arbetet var att utveckla ett fällbord som enkelt kan fällas ihop, ha en längre livslängd och lägre vikt än företagets tidigare fällbord. Samarbetet genererade ett fällbord som inte följer de generella principerna av infällning av bordsben. Resultatet blev ett fällbord med minimal klämrisk, med en längre livslängd då infällning av bordsbenet sker med en vridning och med en mindre vikt då ramverk kan elimineras..

Integrerat växtskydd i svensk jordgubbsodling : attityder bland odlarna till genomförande av det nya direktivet
This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.
Systemförvaltningsmodeller ? verklighetsbeskrivning eller idealiserad bild?
This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".
Val av teknik för hastighetsmätning i kallvalsverk
An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system. One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.
