Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Röntgenbilder: en studie av bildkvalitet inom medicinsk
röntgendiagnostik: en matematisk metod för jämförelse
mellan olika röntgenapparater

I sjukvården världen över tas dagligen tusentals röntgenbilder. Användningsområdena är många, men i de flesta fall är syftet att i något avseende avgöra patientens hälsa. Bilderna utvärderas av läkare för att patienten ska få rätt diagnos. För att läkaren ska kunna göra en korrekt bedömning av bilden och därmed ge patienten den behandling som situationen kräver måste bilden vara rättvisande och vara av sådan kvalitet att alla viktiga detaljer går att urskilja. Bildkvalitet är ett ganska diffust begrepp och ofta används subjektiva bedömningsmetoder för att bestämma ifall en bild är bra eller dålig.

Kommunikation mellan två medium

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

Radiolänk med GNU Radio

At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

Anställningsskydd vid verksamhetsövergång : Vilka rättigheter och skyldigheter övergår?

Transfer of undertaking or business is a complex fact. It requires many aspects to be takeninto consideration. For there to be a transfer of undertaking or business, it has to be a stableeconomic entity that after transfer has retained its identity. The provisions regarding transferof undertaking or business is found in the transfer of undertaking or business directive,6 b § LAS and 28 § MBL.An employee?s employment is automatically transferred to the transferee.

Inkongruenta styrmodeller: En fallstudie av reparation och underhåll i ett industriföretag

In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

?That´s something we people have create in our mind, because we have booring?? : En studie om språklig transfer i elevers skrivande

Syftet med denna uppsats var att studera svenskans påverkan på inlärning av och skriftproduktion i engelska bland elever i svensk grundskolas senare år och gymnasium. Studien genomfördes genom studier av elevtexter på engelska, där mellanspråkliga fel beroende på negativ transfer från svenska till engelska analyserats och kategoriserats. Resultaten visar att negativ transfer främst förekommer i grammatiska mönster som preposition + att-satser, bisatsordföljd, passivkonstruktion och i satser utan korrelat samt vokabulära strukturer som partikelverb och idiomatiska uttryck..

Erfarenhetsöverföring vid svenska utlandsstyrkan : Vilka faktorer påverkar och hur?

The purpose of this paper is to identify the factors affecting the experience transfer at the rotation of the missions. This is to identify the respective influences are inhibitory factor, which contributes to a less efficient transfer, or if it contributes to a more efficient handover. The method used for the production of this paper is a qualitative case study of squad leaders who have done service in Kosovo or Afghanistan. Through interviews with focus on the transfer of experience, both on individual and organizational level, the factors that affect are being identified. The model used is expressed in a general perspective, where each factor is categorized as inhibitory or contributing to success, and if it appears on an organizational or individual level.

Mer än ett pris - : En studie om information, uppfattningar och användning av internpriser.

Background: When companies decentralize their operations into profit centers, transfer pricing often becomes an integral part in intracompany trade. A profit center may affect both revenues and costs and seek to maximize profit. Transfer Pricing is a complex subject because it is affected by a large number of factors including the profit centers will to generate profits. This leads us to the subject of decision-making in a transfer pricing-systems. On what grounds are decisions made? Are transfer pricing purposes, factors and interests taken into consideration? What type of information is used in such decisions, how is the transfer price issue perceived and how is it used?Aim: The purpose of this thesis is to analyze which type of information that is makes up transfer prices, how the transfer price is perceived by different parties and how it is used for decision-making.Completion: A qualitative study has been performed with current theory as a starting point.

SAS EuroBonus ? Tillgång eller skuld?: En fallstudie av hur värdet av ett lojalitetsprogram påverkar internprissättningen

This paper presents a study of Scandinavian Airlines? (SAS) frequent flyer program, EuroBonus. The study describes the transfer pricing of award seats between EuroBonus and the airlines within SAS. Furthermore, it aims to determine what effects market-based transfer pricing would have on EuroBonus, the airlines within SAS and consequently on the SAS Group. We have found that the existing transfer pricing does not provide incentives for the airlines within SAS to satisfy EuroBonus? demand for award seats.

Internprissättningsproblematiken i ljuset av förslaget om hemlandsbeskattning för europeiska koncerner

Throughout this thesis three main factors have been identified that can be out of significance for transfer pricing in multinational companies if the proposal for Home State Taxation is adopted. These factors are rules for calculation of the tax base, rules for dividing costs over periods and the tax rate. The formula for sharing profits will also become a factor that can have an impact on the European companies'incentives for transfer pricing interacting with above-mentioned factors. The effects of transfer pricing aiming at reducing the total amount of the taxation burden for a group of companies will be strongly reduced in the future if the proposal is adopted. Incentives for transfer pricing will loose importance, though not disappear altogether.

Brands Transfer of Meaning: An analysis of brands roles within product placement

Thesis purpose: The purpose of this thesis is to make a contribution, by connecting the transfer of meaning within the context of TV series. The meaning is transferred from the brand to the character in a TV series and then further to the viewer. To look at different role functions that are used in dramaturgy and narrative techniques, we will be able to see how the brand will have a specific role and thereby make the transfer of meaning more successful and effective. This role will have an important impact on product placement according to the meaning that will be transferred from the brand to the viewer, through the character. Methodology: By looking at the transfer of meaning process that is created from the brand, an unstructured observation is applied where we observed the placement and usage of different within a specific TV series. Qualitative strategy is conducted by using a case study.

Internpriser i praktiken: - en fallstudie

This paper presents a study of the Swedish public service television broadcaster - Sveriges Televisions (SVT) transfer pricing model. The aim of the thesis is to examine the motives for using transfer pricing from a theoretical perspective and if SVT?s transfer pricing model fulfils these motives. We will also examine any potential managerial problems the existing transfer-pricing model might cause and discuss how these could be solved. We have in our study found that the main motive for using transfer pricing within SVT is to allocate internal resources as efficiently as possible.
