The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

Accessibility is today a topic of high current interest. It is a requirement for equality and a democracy question. By the year 2010, easy measured hindrances in all of Sweden's municipalities should be cleared away; this is stated in Swedish law. The physical accessibility to our public places is particularly important for functionally disabled people since it affects their possibilities to be outdoors and also their participation in society. When designing these places, it is difficult to find solutions that fit everybody, especially since good accessibility not only should fulfill all physical requirements of accessibility but also values of experience.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

The purpose of this study was to investigate the reason behind thedecision by a company regarding the desire to use mobile access to theirERP-system and to discover whether this will involve any loss offunctionally in comparison to using the ERP-system on a computer atthe office. In addition, the pros and cons involved in using mobiledevices for accessing the ERP-system will also be examined. Semistructured telephone interviews were conducted with companies whicheither used or did not use mobile devices in relation to their work. Atelephone interview was also conducted with a consultant who isworking with the implementation of ERP-systems and mobile solutions.The survey showed that companies with staff working in the field assellers, service personnel and construction workers want to gain directaccess to their ERP-system so as to be able to act directly and takedecisions, to have the ability to provide more efficient order processingand to send out invoices more quickly. Those companies which have notopted to use mobile devices at work within this field are those whichare unsure of the connection to the Internet and the capacities availablewithin cellphones.

Studien bygger på två 24 timmars ljudinspelningar utförda från två olika städer iSverige. Syftet med undersökningen var att se om det gick att urskilja akustiskaskillnader mellan två olika städer i Sverige. Studien har tagit mycket inspiration av R.Murray Schafer arbeten inom soundscaping, samt Pijanowskij, et al., (2011) ramverkför att kunna kategorisera ljuden utifrån dess ursprung och funktion. Olikaundersökningar har genomförts med hjälp av kvalitativa intervjuer, samtfrekvensanalyser av det inspelade materialet. Båda metoderna användes tillsammansvid utvärderandet av ljudmaterialet för att se hur vida informanternas svaröverrensstämde med den frekvensanalys som genomförts.

Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.

This paper discusses whether the main argument for European countries to stay out of the euro, i.e. the loss in stability from not having a national monetary policy that can be used for stabilization purposes, is still valid ten years after the introduction of the single currency. We analyse the stabilization performances of four largely comparable Nordic countries that have all chosen different levels of European economic integration. In retrospect, the so-called ?stabilization policy argument? seems surprisingly weak.

Seven individuals from Surahammar in Västmanland Sweden are analyzed for the appearance of pathological and skeletal changes. The graves, all from within the walls of a fourteenth century church, are dated from the Viking age to late eighteenth century. The aim of this scientific essay is to find pathological conditions by doing an osteological analyze, x-ray analysis, an osteoporosis measurement and letting orthopedists assess the individuals. The aim is also to say something about the individuals? general health and how they experience the changes they have in the skeleton.

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

En hörselnedsättning är en kommunikationsstörning som starkt påverkar en bebis utveckling på många områden, inte bara ljudperception och talad kommunikation. I Sverige screenas idag alla bebisar redan på BB, för att så tidigt som möjligt upptäcka medfödda skador. Dessa metoder har dock informationsbegränsningar angående hörselnedsättningens grad och frekvensberoende. När bebisar är ett halvår gamla kan den observerande audiometriska metoden Visual Reinforcement Audiometry (VRA) användas för att utreda hörselnedsättningen. Metoden baseras på att en audionom gör en subjektiv bedömning om bebisen reagerar och vänder huvudet till följd av presenterade ljudstimuli med känt frekvensinnehåll och känd ljudtrycksnivå.

Due to the wide usage of different databases administrated by the Swedish government to keep control over its citizen?s the issue has arisen concerning if this information is subject for other purposes then originally acknowledged. Executives induced in recruitment for labour has over the years extended their need for information accumulated by these systems. Especially data from the criminal records registry are now being used as a normal step in the employment process among a vastly growing spectrum of enterprises and businesses all over the country. This thesis aims to illuminate the subject by grasp to what extent the described behaviour can be considered legally accepted according to the law or if these actions are inflicting with the foundational juridical principles that has to be ensured by the Swedish government due to our constitutional law.A strict jurisprudential method has been applied throughout the entire thesis to ensure the reliability of the results. The diversity of sources has gently been put together to assure the overall quality.

The purpose of this final thesis is to investigate the effects of seasonal changes in the horticulture industry. In this study this includes mainly garden designers, constructors of gardens and parks and horticultural businesses at Österlen. Today the most important issue,both in private and in public environment, is that the winter occupation in this area is not big enough. The consequence of this issue can result in the loss of competence to other industries if educated personnel has to stay employed only over season. The study is trying to identify and rank factors that are contributing to the problem, and propose solutions that means work opportunities for companies in the horticulture industry as well as for their employees, during twelve months of the year..

The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.
