Energieffektivisering av industribelysning : Planering av belysningsanläggning i mekanisk verkstad

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.

Avsikt, insikt och moraliskt ansvar : En genomgång av diskussionen gällande doktrinen om trippel effekt mellan Frances M. Kamm och John Harris.

This work is meant to contribute to the research of adaptation studies by focusing on a special case: the transformation of a fictional diary into a movie. In order to sustain the form of the literary source the adaptation to movie requires certain strategies. Först of all, the diary genre is characterized by a one-dimensional narration. Second, diaries only supply a few written dialogues, hence this "void" has to be compensated and filled by media specific measures. Third, the investigated diary is a story of individualization and emancipation of a single woman.

Autopositionering för röntgensystem

AbstraktRöntgen är ett område där man ställer frågan om processen skulle kunna automatiseras för att göra den enklare för sjuksköterskor. På så sätt ökar antalet patienter som kan röntgas eftersom det skulle gå snabbare. Med hjälp av datorseende och en servostyrd röntgenkamera kan man förverkliga delar av dessa drömmar genom att låta röntgenkameran själv justera sig efter en patient och även flyttas till en vald kroppsdel.Här undersöks och testas open-source biblioteket OpenCV. En prototyp på ett automatiskt system tas fram med syftet att testa OpenCVs funktionalitet och besvara ett antal frågor:Hur kan röntgen automatiseras genom användning av open-source programvarubibliotek med inriktning på bildbehandling?Vilka för ? och nackdelar kan användandet av ett datorseendebibliotek vara?Kan man med dagens teknik utveckla en automatisk lösning som kan göras till en kommersiell produkt?.

Den kritiska Messengergenerationen : En studie om politiska diskussioner i sociala medier samt skolans roll i att forma kritiskt ta?nkande individer

The purpose of the study is to explore how social media can be used as a forum to discuss politics and also how young people use critical reflection to evaluate the information available on social media. To achieve the purpose, a qualitative research is used. The empirical data is collected through semi-structured interviews with six high school students who voted in the Swedish parliamentary elections in/of 2014. The empirical data were then analyzed based on previous research on social media, and the school's mission to foster individuals who think critically. The analysis is also based on the theory of deliberative democracy model.

Att göra det osynliga synligt : En adaptionsstudie av en filmatiserad dagboksroman

DYNAMIKEN OCH EFFEKTEN AV MARINA V?RMEB?LJOR P? TROPISKA KORALLER (SCLERACTINIA)

Marine heatwaves (MHW) have become increasingly common in recent decades due to greenhouse gas emissions that have caused climate change. A marine heatwave is when the sea surface temperature rises, which damage many different ecosystems in the sea. One ecosystem that is sensitive to temperature changes is tropical coral reefs, which are at risk of bleaching during marine heatwaves. Coral bleaching is when its symbionts leave the coral and they lose their color, while also starving to death as they lose their food source. The purpose of this report was therefore to investigate what the connection between marine heatwaves and coral bleaching looks like, and to see if there are any geographical differences.

Kunddriven tjänsteutveckling? - en kvalitativ studie av Scandinavian Airlines.

The deregulation during the last decade within the airline businesses have called upon a more fierce competition among airlines. This fact forces airlines to continuously focus on service development in order to offer attractive solutions to satisfy customers changing needs and stay competitive. This paper focuses on service development at Scandinavian Airlines. The aim of this case study is to examine the sources of information used in service development and new service development at Scandinavian Airlines. Further the aim is to examine whether information derived from customers can be shown to play a more important role in either service development or new service development.

Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Ombyggnation till passivhus

Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.

Vilken Open Source SIP-server lämpar sig bäst förAndroid?

Denna studie tacklar ett av de problem som modern IP-telefoni brottas med, som gör att det är svårare att konkurrera med traditionell telefoni: fördröjningar på grund av otillräckliga Session Initiation Protocol-servrar (SIP). Genom tester av de viktigaste faktorerna jämförs fyra högaktuella Open Source SIP-servrar: OpenSIPS, Kamailio, FreeSWITCH och Yate. Avsikten är att underlätta valet av SIP-server för nya applikationer inom IP-telefoni, öka prestandan samt snabba på utvecklingen. Studien behandlar de intressantaste faktorerna vid val SIP, såsom användarvänlighet, hastighet, lagring av användardata samt ljudkvalité. Slutsatsen blev att Kamailio stod som klar segrare, med överlägsna resultat i jämförelse med övriga servrar, på de parametrar som valts ut.

Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

Brännskuggat fanér - en metodanalys

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

Avvikelser i energiprestanda

Calculated and measured energy in residential buildings is going to differ. The reason to this may be due to many factors. In this study there is a study on how these factors affect the energy use in a building. To get an insight in what defines energy, there is first a description of energy supply both worldwide and used in Sweden, followed by a description of the energy balance. In this study energy will be studied in residential buildings only.

Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

Utvärdering av Windows RT för portning av Mario Framework

Ericsson har utvecklat ett ramverk för multimediakommunikation som heter Mario. Mario kan användas för att sätta upp video- och ljud-samtal över IP och finns fungerande på Android och iOS. Mario är en del av web browsern Bowser som finns att hämta på Google Play eller App Store. Bowser möjliggör att köra WebRTC applikationer skrivna i HTML5 och JavaScript på Android och iOS.Nu när Microsoft släpper sina nya plattformar, Windows RT, Windows 8 och Windows Phone 8 så finns ett intresse att försöka flytta detta ramverk till dessa plattformar. Vi kommer göra ett försök att porta Mario till Windows RT.
