Power supply monitoring for wireless sensor platforms
Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Probiotikas inverkan på sjukdomsförloppet hos intensivvårdspatienter. : En metaanalys till grund för evedensbaserad omvårdnad
Bakgrund och syfte: Intresset för enteral administrering av probiotika i förebyggandet av infektioner och diarré har på senare tid ökat. Nosokomiala infektioner och diarré är ett stort problem hos intensivvårdpatienter. Syftet med denna studie var att undersöka hur enteral probiotika påverkar sjukdomsförloppet hos intensivvårdspatienter, med avseende på mortalitet, infektioner totalt, ventilatorassocierad pneumoni (VAP) och diarré.Metod: En systematisk litteraturstudie med sökning i Pubmed och Cinahl genomfördes med följande Meshtermer; probiotics, lactobacillus, critical illness och intensive care unit. Därefter genomfördes en metaanalys av randomiserade kontrollerade studier, utförda på vuxna intensivvårdspatienter, där man jämfört patienter som erhållit probiotika med patienter som fått placebo eller annan behandling.Resultat: Totalt 15 studier med sammanlagt 1293 patienter inkluderades. Ingen signifikans med avseenden på mortalitet, infektioner totalt, VAP och diarré kunde utläsas i metaanalysen.
Presentation av taktisk information på bildskärm : Head-Up Display som stöd för tidsstyrd taxning med flygplan
Syfte: Syftet med uppsatsen är att tillämpa aktionsforskningsteorin och metoden appreciative inquiry vid design av en måltidsupplevelse med målsättning att öka medarbetarnas medvetenhet kring stolthet över arbetsplatsen, inspiration till matlagning samt mod och vad som får människor att våga testa nya produkter och arbetssätt. Ett ytterligare syfte var att utveckla ett mätverktyg som utvärderade insatsen och fångade upp medarbetarnas tankar och känslor. Till sist är det även uppsatsens syfte att utvärdera inbjudan till den designade måltidsupplevelsen för att kartlägga vad som väcker intresse och nyfikenhet samt vad som får medarbetare att anmäla sig för att delta på evenemanget.Design/metod: Arbetet är en fallstudie och har utgått från aktionsforskningsteori och -metodik med specifikt fokus på appreciative inquiry. Eftersom arbetet har varit tätt kopplat till utveckling av en målitdsupplevelse har även inspiration och kunskap hämtats från mat- och måltidsbranschen.Resultat: Ett nytt måltidskoncept har utvecklats och presenterats. Eftersom den designade målitdsupplevelsen fusionerar appreciative inquiry och måltidskunskap har det givits namnet appreciative dining.
Hantering av verksamhetskrav : Utredning av hur hantering av verksamhetskrav från kunder kan förbättras på Saab Aerosystems
Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.
TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Since the very beginning Olsson's garden has played a lot of different rolls in a variety of situations and meant different things for different people.
Today one can find traces from Mr Olsson's life and deeds in the garden.
Verksamhetsstyrning i Stockholmsstad : En studie av verksamhetsstyrningen i Skarpnäcks stadsdelsförvaltning
This paper is a study of corporate governances in the municipal of Stockholm. The purpose of this paper is to enlighten the problems and opportunities for the corporate governances of the wards in the municipal of Stockholm. The municipal of Stockholm is made up of 18 relatively self-governing wards, whose activities bear a resemblance to one and other. Therefore we have specified our survey to corporate governances in the ward of Skarpnäck (Skarpnäcks stadsdel), to be able to use this ward as an example to corporate governances in the entire municipal of Stockholm. The essay emanates from the important management theories: Budget, Integrated Management system (ILS), Benchmarking and Balanced Scorecard.The essay is based on interviews and a poll survey we conducted in the administration of the ward of Skarpnäck, and also based on interviews with Stockholm?s city hall.

Objektiv utvärdering av hälta under ryttare
Background: The most common reason for veterinary care in horses is lameness. Lameness in riding horses is often difficult to evaluate and in many cases may require riding to come to a diagnosis. Evaluation of lameness has proven to be very subjective and depends on the examiner. There is a need to evaluate ridden horses in an objective way.
Lättridningens påverkan på hästens rörelsemönster i trav :
The interest in horses and equestrian sport is constantly increasing, and so is the will in both riders and trainers to learn more about the effect the rider and its equipment have on the horse. The last twenty years, more and more studies have been performed were the horse and its kinematics have been in focus. The access to more advanced technology has made it possible to study areas, which earlier have been hard to reach. The knowledge about kinematics in the horse, and how riders and their equipment interact with the horse?s movement, is also of great interest to veterinarians in equine practice.

Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad
Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.
