This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

The main purpose of this essay is to investigate if Latvia´s pattern of trade has become more similar to the mature market economies, after Latvia´s independence 1991.Today, the intra-industry trade (IIT) dominates the trade of mature market economies. One of the pioneers of intra-industrial trade is Paul Krugman, who was the first to emphasize the importance "of scale and consumers' desire for variety" in explaining the basis for modern commerce. Customers get more variety and usually cheaper goods when the market gets bigger. I mainly use the modern trade theories to explain the trade pattern in Latvia. To measure how Latvia has developed its intra-industry trade, and thereby is approaching the mature market economies´ trade pattern, I use the Grubel-Lloyd index (GL-index).

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Gruppen Kvantitativ Logistik (KL) vid Linköpings Universitet har under en längre tid efterfrågat en simuleringsbaserad utbildningsmiljö där produktionsplanering kan upplevas i form av planering, omplanering och kapacitetsberäkningar. Denna utbildningsmiljö ska framförallt användas för att utbilda andra studenter inom produktionsplanering. Miljön ska bestå av ett användarinterface där all data om produktionen framgår, en simuleringsmodell som utgör själva fabriken samt en sammanhållande struktur som möjliggör styrning av de båda komponenterna. Dessutom skall ett antal scenarion skapas som skall ligga till grund för de lärandemoment som MPCW hanterar.Fyra fiktiva produktstruktur skapades, på så sätt att deras komplexitet och djup var tillfredsställande. Dessa strukturer ligger till grund för de MRP- och sedermera CRP-beräkningar som används för att styra de ursprungliga aktiviteterna.Resultatet av examensarbetet är ett verktyg som kan användas för att simulera produktionsplaneringsarbete. Verktyget består av två huvuddelar, den ena är ett GUI (Graphical User Interface) i Excel som kallas för MPCW (Material Planning and Control Workbench) och en simuleringsmodell.

This report represents a comparison between two different tools used to create an online store that was developed by two students at the Technical University in Jönköping. The web shop will be of great benefit to both customers and administrator in a food firm known as Mattias' Livs. The company wanted an online store that facilitates the sale section and gives a full control of their stocks. The aim of this thesis is to create an online store that offers customers the ability to shop online and help the staff to operate the company in a simpler and more efficient way, which reduces the need for human resources and thus leads to less costs for the company. The aim also includes a comparison between the two different tools used to create the online store.

Det här examensarbetet som är utfört hos Telia Research AB behandlar opto-elektriska korskopplare (OEXC) i ett modellnät. Arbetet omfattar två delar, en karaktärisering av OEXC:er tillverkade av en specifik leverantör och en nätanalysdel. Karaktärisering av OEXC:er bestod av mätningar utförda i laboratorium på Telia Research AB. Mätningarna syftade till att finna fel och brister hos korskopplaren inför ett fältprov. Mätningar utfördes på fyra OEXC:er.

Denna studie syftade till att ta fram ett ramverk för utveckling av API:er för tjänsteorienteradearkitekturer. Studien tar sin utgångspunkt i forskningsprojektet e-Me (utvecklingenav en integrationsplattform för att underlätta studenters vardag) samt en benchmarking avde i nuläget mest använda API:erna på webben. Studien har fem faser: En litteraturstudie,en benchmarking, en kvalitativ genererande intervjustudie, en teoribildande fas (framtagningav ramverket), samt en kvalitativ validerande studie. Litteraturstudien tar upp sådanafenomen som utvecklingsmetoder, systemarkitekturer (bland annat SOA) samt metautveckling.Denna studie låg till grund för den första intervjustudien, som i sin tur låg tillgrund för benchmarkingen. Resultatet av dessa två studier bildade tillsammans en grundför ramverket SOAPIF (Service-Oriented Application Programming Interface Framework),som till en början innehöll fyra olika faser: Conceptualization, där man försökerbilda sig en uppfattning om vad API:et skall exponera; Definition, där man försöker definieraett kontrakt för API:et; Testing & Implementation som tar sin utgångspunkt i testerför att implementera API:et; samt Delivery, som är den fas där API:et skall levereras.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Tester som utfördes var: Konfigurering av noder och länkar, transmissionstester, skyddsomkoppling, tillförlitlighet och stabilitet.

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

Det bör vara möjligt att skapa verktyg för att beskriva scenarion och med hjälp av tillgänglig mjukvara för visualisering kunna spela upp både verkliga och simulerad bilddata. Detta examensarbete beskriver hur några sådana verktyg tagits fram. Till förfogande fanns en stor mängd bilddata, insamlad på ett militärt övningsområde som dessutom finns representerad som en syntetisk omvärldsmodell. Insamlingen gjordes med en UAV (Unmanned Aerial Vehicle)- prototyp, som var utrustad med videokamera, IR-kamera och tröghetsnavigeringssystem. För att simulerad bilddata skulle få ett verklighetstroget intryck placerades markfordon ut i den syntetiska modellen på exakt samma position som under fältförsöken.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

AbstractAim of the study: Aim of the study was to investigate whether there were any connections in time between different parts of care in patients with cardiac arrest and hypothermia treatment and cognitive and physical function six months after cardiac arrest and to investigate neurological outcome related to primary registered cardiac arrest rhythm after six months and if there were any changes in cognitive and physical functions as well as self-related health between discharge from hospital and six months after cardiac arrest.Method: The study included 39 patients admitted to three Swedish hospitals between 2008-2011. Cognitive and physical function was evaluated with Cerebral Performance Cathegory, CPC completed with Mini Mental State Examination, MMSE for cognitive function and Bartels Index, BI for physical function and Euroqol-VAS for evaluating the self-related health.Result:  A significant connection was shown between time to start hypothermia treatment and BI, patients with longer time showed improved physical function after six months.Majority of the participants (66,7 %) had Ventricular fibrillation/Ventricular tachycardia, VF /VT, as primary registered cardiac arrest rhythm and in this group CPC and BI was significant better compared with the asystole /Pulsless Electrical Aktivity, PEA group.CPC, MMSE, BI and Euroqol-VAS were all improved over time.Conclusion: Participants with VF /VT as primary registered cardias arrest rhythm had significant better cognitive and physical function 6 months after hypothermia-treated cardiac arrest compared with participants with asystole/PEA as primary registered rhythm. This shows the importance of access to defibrillators in public places in the society and in hospitals and optimal education of lay people and medical staff. Cognitive and physical function and self-rated health improves over time, which might be a very important reason to convey patients, relatives and medical staff to continue cognitive and physical rehabilitation. Keywords: Cardiac arrest, hypothermia, cognitive and physical function, wellbeeing.
