Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Uppsatsen gör en genomgripande kvalitativ analys av redovisningens roll i institutionsteatern, i två fallstudier, med fokus på synliggörande av värdeskapande. Syftet är att öka förståelse för redovisningens funktion vid styrning av verksamheter med icke-finansiella mål. Ytterligare en ambition med uppsatsen är att föreslå ett förhållningssätt till icke-mätbara värden i redovisning och styrning.Inledningsvis presenteras de två analysobjekten som valts för fallstudier; Stockholms stadsteater och Västerbottensteatern. Genom samtalsintervjuer och observationer gör författaren närläsningar av analysobjekten som sedan relateras till utvald litteratur, praktiker och modeller av relevans för studien. Här förs resonemang kring de båda analysobjekten utifrån rådande teori inom redovisning, styrning och arts management.Studien antyder att redovisningens roll i teatern är mångfacetterad; den fyller en inre och en yttre funktion, i en konkret respektive abstrakt dimension.

Detta arbete inom prestationsmätning av effektiv logistik är utfört på Scanias produktionsenhet MB i Oskarshamn. Denna produktionsenhet tillverkar hytterna till Scanias lastbilar på europamarknaden, från plåtrulle till färdigmålad hyttkaross. Produktionsenheten MB består av en pressverkstad, en karossverkstad och ett måleri.Uppgiften i detta arbete är att utveckla ett antal mätetal för prestationsmätning av MB:s internlogistik, och utifrån dessa ge förslag på förbättringsmöjligheter i verksamheten.Uppgiften löses genom att använda Bourne och Neelys metoder för utveckling av mätetal, så som en framgångskarta för den kritiska framgångsfaktorn effektiv logistik och utformandet av ett definitionsblad, vilket explicit definierar varje mätetal. Detta tillsammans med Parmenters definitioner angående mätetal och arbetssätt vad det gäller prestationsmätning, avser att spegla moderna tillvägagångssätt för prestationsmätning och för implementering av dessa i ett företag.De mätetal som rekommenderas för implementering i MB:s logistiska verksamhet är trucktimmar per hytt, leveranspålitlighet, lageryta, energianvändning per hytt för transporter och materialhanteringskostnad per hytt. Flera förbättringsförslag rekommenderas också vad det gäller den förbättringspotential som finns vid införandet av en gemensam materialhanteringsfunktion på MB.

The health care sector is one of the most information-intensive institutions in Sweden. Big investments in information technology have been made to ensure efficiency and quality within organisations in health care. This has led to high requirements in documentation and resulted in an increase in administration which gradually more often is done by nurses and doctors. A major problem is that it is difficult to gain access to the information recorded in all the different systems, which is their objective. This causes double documentation instead of being a support in follow-up performance.

The aim of this thesis is to study whether social welfare secretaries experience occupational pride and what affects this feeling. Previously made research indicate that occupational pride is essential for performance and work-related health. Research has also shown that social welfare secretaries often experience unhealthiness due to working conditions and a lack of professional self-esteem.This thesis is based on four qualitative interviews which have focused especially on critical incidents, according to the critical incident technique. This study has a hermeneutic, interpretative approach. As a theoretical framework, Pierre Bourdieu? s theory on social space and positions aswell as Aaron Antonovsky´s theory on Sence of coherence have been used. The result shows that the interviewed social welfare secretaries do experience occupational pride.

The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.

Enligt Socialstyrelsens föreskrifter om ledningssystem för kvalitet och patientsäkerhet i hälso- och sjukvården, SOSFS 2005:12, krävs det av vårdgivaren att denne arbetar efter mål. Att formulera mål inom hälso- och sjukvården kräver eftertanke. Målen måste vara mätbara och inkludera flera olika delar av verksamheten. Varje förbättringsprojekt är unikt och bör relateras till de resurser som avsatts. Ett stort problem vid kontinuerlig uppföljning är att välja ut parametrar som ger tillräcklig information och är lätta att skapa.

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

This bachelor thesis is an exploratory investigation about the phenomenon 'Gamification', which by some definitions is about implementing game elements into non-game contexts. For example exercise services as Runkeeper and Nike Plus who both are available on android and iOS platforms. This study is mainly about the potential value of gamified systems and services for companies and its users and how such a system or service is developed. The thesis also discusses the development aspect of gamified systems in order to give the reader a more ?in depth? understanding about the phenomenon.

Vid mätning av HbA1c i blod visas medelkoncentrationen av glukos som en person har haft under de senaste tre månaderna och analysen används vid uppföljning av patienter med diabetes mellitus. DCA VantageTM är ett patientnära analysinstrument som utvecklats för att kunna utföra laboratorieanalyser inom till exempel primärvården. Patientnära analysinstrument är viktiga för att minska tiden från provtagning till behandling. DCA VantageTM är ett halvautomatiskt analyssystem som utformats för kvantitativa mätningar av HbA1c i blod. Syftet med studien var att utföra en verifiering för att se om DCA VantageTM (immunoturbimetrisk metod) kunde användas som ett komplementinstrument till VariantTM II Turbo (high performance liquid chromatography, HPLC).

The purpose of this essay is to examine how administrative officers at the Swedish social insurance agency experience and deal with the goal conflicts they may experience. Furthermore, the purpose is to gain a greater understanding on how they perceive their role in the implementation process, and their position as the link between the citizens and the state. Two potential conflicts are examined; between quantitative goals and performance measures and those more qualitative and hard to measure; between economic values such as cost efficiency and productivity and democratic values such as the rule of law. The other conflict examined is that between implementing and following the laws set forth, take into account the individual needs and interests of the citizen. The theoretical framework consists of Lundquist?s theory on public officers as the guardians of democracy, which means that they should not only implement laws and rules according to political intentions, but also make sure that the democratic values and principles are followed in the relationship between state and citizen.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.

The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.

This master?s paper first presents some of the principal theories and concepts developed by the poverty researchers Rowntree, Titmuss, Townsend, Sen and Lister. These theoretical frameworks are then related to two documents from the EU and Sweden concerning combating poverty and social exclusion, bearing on the establishment of the ?Year 2010 against Poverty?. Finally, I discuss the value in practice of these theories and policy documents, as regards reducing poverty in Europe.It has become clear in this investigation that the theories and concepts from earlier research are still relevant to the formulation of contemporary policy programmes, and that earlier research helps us to avoid old traps in fighting poverty.
