Syftet med denna uppsats är att modellera och prognostisera Sveriges varuexport, varuimport och handelsnetto. Vi använder oss av data från januari 1975 till och med augusti 2010 för respektive serie. Dessa data testas och jämförs i olika ARIMA- och SARIMA-modeller samt skattas även medelst säsongsreningsprogrammet TRAMO/SEATS. För de modeller som bäst passar serierna genomförs därefter in sample- och out of sample-analyser med felmåtten RMSE och MAPE. Modellerna med bäst felmått och som därpå väljs ut för att göra prognoser för serierna till och med augusti 2012 är (3,1,0)x(0,1,1) för export, (2,1,1)x(0,1,1) för import samt (0,1,1)x(0,1,1) skattad i TRAMO/SEATS för handelsnetto..

Uppsatsen grundas kring teorier om att aktiemarknadens aktörer är relativt dåliga på att förutspå aktiers utveckling. Den helt rationelle investeraren som är en av grundstenarna för teorin om den effektiva marknadsportföljen verkar ej existera. Den effektiva marknadsportföljen, praktiskt uttryckt som ett marknadsvärdeviktat index, blir då en olämplig förebild att följa vid investeringsförfarande. Vidare grundas undersökningen på teori vilken antyder att historiska resultat ger en god indikation om företags framtida utveckling. Vi har studerat en stor mängd företag noterade på den svenska börsen under perioden 1992-2003.

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

Flera företag har använt sig av paralleller till idrotten för att motivering sina anställda, vilket inte är överraskande då passionen och drivkraften att uppnå sina mål är stark hos idrottare. Uppsatsen ämnar därför undersöka om det finns likheter hos säljare på medieföretag och brottare i en idrottsförening. Dessa organisationer valdes eftersom det ansågs föreligga likheter i deras sätt att arbeta och träna. För att i mesta möjliga mån få del av respondenternas tankar kring vad som motiverar dem valdes semistrukturerade intervjuer som metod för insamlig av data. Data analyserades sedan utifrån Maslows behovshierarki samt Herzbergs tvåfaktorteori..

This report tested the possibility of using induction as a mean for transferring data and power so that it can be implemented as a communication medium between a terminal and measuring head mounted in a measuring frame. This would eliminate the need for the cable bunches that are used today. For testing, signal generators were used to generateFSK-signals and were transferred with the help of inductors to the oscilloscope for signal detection, this to see how the coils used in the tests behaved. Simulations of a PLL were performed to see how good it could handle FSK-demodulation. With the help of a PLL IC and the simulations a working FSK-demodulator could be assembled.

Precis som titeln avslöjar handlar rapporten om att utveckla ett system som kananvändas vid utvärdering av övningsmoment. Idag saknas ett liknande system somvara ett stöd för hemvärnets instruktörer vid utvärderingar som har till syfte att ökaförståelsen hos övande personal. Systemet består av en mobilapplikation och enwebbapplikation. Mobilapplikationen loggar hur en soldat har framryckt under ettövningsmoment och sedan sammanställs data från en eller flera mobilapplikationer ien webbapplikation där data visas på en interaktiv karta. Kartan ger möjlighet attstega sig igenom händelseförloppet.

The purpose of this essay was to examine female immigrants of South East Asia who have lived together with a drug addict and how they were affected and let themselves be influenced by that, and to study their reactions to such situations.The main questions were:· How do the women describe their personal relationship matters with their husbands with focus on abuse / co-dependency?· How do they show their co-dependency in actions?· How do the women handle their co-dependency?I chose a qualitative method because my purpose was to get a comprehension and hopefully find a pattern in the life situation in this specific target group. Regarding the collection of dataI used both primary data in the frame of interviews with persons connected to the problem, and secondary data in the form of earlier studies in that field.As the main result I found that these women lived in a severe stress. They were affected both psychically and physically by the abuse of their partners. They developed different strategies of survival to stand the reality and to save the family.

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

Inom ramen för projektet ?Kiruna referenskommun? har Tekniska Kontoret gett i uppdrag åt Metria IT i Kiruna att utarbeta en applikation i ArcView för hantering av det kommunala VA-nätet. Uppgiften för detta examensarbete var att bygga en del av applikationen. Arbetet inleddes dock med en förstudie av alternativa system för ledningshantering. Bland andra kan nämnas KORDAB och Vabas/Duf vilka båda är specifika VA-program med ett omfattande antal funktioner.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
