En ökad efterfrågan på biogas har lett till att matavfallsinsamlingen i Sverige ökar, då detta är en god råvara för produktion av biogas. Det finns flera olika insamlingssystem att välja bland, alla med sina för- respektive nackdelar. Beroende på vilket insamlingssystem som implementeras, får detta konsekvenser för hur renhållningsarbetarnas arbetsmiljö blir. Vad renhållningsarbetarna själva anser vara viktiga aspekter för en god arbetsmiljö samt hur dessa aspekter påverkas av de olika insamlingssystemen har hittills varit okänt. Genom systemanalys innehållandes fallstudier, Corporate Social Responsibility-analys (CSR) och skapandet av Casual Loop Diagrams (CLD) har problematiken undersökts i detta arbete.

Detta examensarbete pågick under fem veckor på SSAB i Luleå och behandlar två uppgifter. Den första uppgiften gick ut på att forska om tid för att på bästa sätt kunna tidsätta nätverksutrustning samt övervakningsplattformar på SSAB. Den andra uppgiften gick ut på att undersöka krav samt upplägg för övervakningsplattformen SCOM. För att kunna synkronisera tid används i huvudsak tre protokoll: NTP, SNTP samt PTP. De vanligaste teknikerna för att synkronisera tid är via internet, GPS, radiokommunikation samt manuell tidsättning.

Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.

Examensarbetet berör vilka faktorer som de boende i ett visst område värdesätter i sin utomhusmiljö. Arbetet baseras på en enkätundersökning där svaren har sammanställts i tabeller och diagram. Vad som gör ett område attraktivt är personligt och beror på många olika aspekter, vilka vi har försökt att fastställa i arbetet..

This paper examines which media messages related to happiness that can be found in interviews with famous people in the four largest lifestyle magazines in Sweden for the age group 16-34. The magazines are Cosmopolitan, Elle, Café and King. Depending on which magazine the reader chooses to read he/she will be presented with different roads to happiness. Common for all examined magazines are happiness factors related to personal goals, determination and work. Often in a causal connection where the goal orientation and determination is tied together with success in work and career for the interview persons.

Avfall Sverige äger två certifieringssystem: SPCR 120 Biogödsel och SPCR 152 Kompost. Dessa två certifieringssystem används för att certifiera biogasanläggningar och kompostanläggningar. Certifieringen säkerställer att biogödseln respektive komposten har en hög kvalité och kan användas inom till exempel jordbruk. Certifieringssystemen har varit i bruk sedan 1999 och har än så länge resulterat i åtta certifierade biogasanläggningar och tre certifierade kompostanläggningar. Det är SP Sveriges Tekniska Forskningsinstitut som genomför besiktningarna ute hos de olika anläggningarna samt ansvarar för utfärdandet av certifikaten.Denna rapport föregicks av en inläsning på certifieringsreglerna SPCR 120 Biogödsel och SPCR 152 Kompost, samt genomgång av samtliga besiktningsrapporter från 2005 och framåt.

There is much research into the reasons why a temporary pain, in some individuals, becomes chronic. Many of the causal factors linked with pain also seems to coexist with social anxiety, public self-consciousness and, to some extent, private self-consciousness. The purpose of this study was to investigate and identify possible patterns of self-consciousness (private and public), social anxiety and pain. This was done by a cross-sectional study in which a questionnaire was distributed to students at Örebro University. A total of 302 completed questionnaires were received.

Idag ses ett ökat intresse för användandet av rörelseanalys inom olika sammanhang t.ex. övervakning, dataspel och diagnostisk undersökning av personers rörelsemönster med mera. Optisk rörelseanalys är den teknik som finns mest idag, men de systemen är dyra och saknar lämplig mjukvara för klinisk användning.En forskargrupp vid centrum för medicinsk teknik och strålningsfysik (CMTS) forskning och utvecklings avdelning (MT-FoU) vid Norrlands universitetssjukhus har sedan 2007 jobbat med en produktidé som bygger på att skapa ett nytt mobilt system för rörelseanalys som kan användas i medicinska undersökningar. Ett Arduino pro mini kort samt ett 9-axligt prototypkort som består av MPU-6000 och en magnetometer HMC5883L är anskaffat för att tillverka ett system i detta syfte.Syftet med projektet har varit att skapa ett verktyg som kan samla in rörelsemönster för att sedan presentera resultatet i ett diagram. Systemet skulle kunna samla in data från en sensor som inkluderar en 3D-accelerometer ett 3D-gyroskop och en 3D magnetometer för att därefter skicka det vidare till en dator där mätdata presenteras visuellt och sparas undan i en textfil.En viktig detalj att ta hänsyn till vid konstruktionen av det nya systemet var att konstruktionen gjordes med hjälp av billiga standardkomponenter och kretskort.

The consultancy firm Knowit sought a smartphone application for communication between schools and pupils. Together with the students, it was decided to create the app both for Android and for iPhone. The project would produce a prototype app with limited functionality usable as a proof-of-concept in communication with potential customers.The questions that have characterized the work are; what features would be demanded in a school app, how to program user-friendly functionality and how to use object-orientation to design such an app. A question has also mentioned the differences between development for iOS and Android. The work was done in an iterative process in which the students worked together with planning, programming and testing.

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

All new households were to be constructed with "near zero energy house standards" (NZE-house) by the year of 2020. The ambition to construct energy-efficient buildings had to increase rapidly in the spring of 2013.The purpose of this report was to increase the interest for building contractors to construct apartment buildings with passive house standards. By locating and evaluating experiences from an existing passive house a case study including interviews, field visits and document analysis was made. Research of literature regarding other passive houses in Sweden also helped to answer the following questions:- What positive and negative experiences have the study of the passive house meant to the involved stakeholders and residents?- What improvements can be made based on identified experiences?- How can an apartment building be designed as a passive house based on possible improvements?By collecting good and bad experiences, as well as improvements and potential design proposals, a diagram was created designed as a tool for developers when constructing apartment buildings with passive house standards.

This study is about differences in knowledge regarding animals. In the study five year old preschool children from a city were compared to five year old preschool children in the suburbs with multicultural background. The study is also about where children´s knowledge about animals comes from and how educators can make a positive difference. To find this out standardized interviews was used on 23 children from four different preschools, two preschools in the suburbs with 15 children and two preschools in the city with 13 children. A survey was sent out to the educators within these preschools to gather background information on what the children do regarding animals.
