FPGA-design av en STDM-baserad multiplexer för seriell multiprotokollskommunikation

The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.

Utvärdering och uppdatering av typkurvor

The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.

Prediktering av fartygsbränsleförbrukning i varierandesjötillstånd

  During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today?s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions.

Den militära nyttan med ett digitalt eldledningsstödssystem vid precisionbekämpning

Då dagens konflikter ofta utspelar sig mitt ibland civilbefolkningen och där aktörerna kan utgöras av allt från miliser till kriminella gäng ställs det nya krav på de militära förmågorna för att kunna agera i dessa komplexa miljöer. En generell trend för dagens artilleriförband är att de används till att verka mot mindre målgrupper utgörandes av två till fyra personer. Erfarenheter från konflikter i likhet med de i Irak och Afghanistan har visat på vikten av tillgång till precisionsbekämpning med indirekt eld för att undvika förluster bland de civila. En förutsättning för att kunna genomföra precisionbekämpning är att målets position kan lägesbestämmas med en mycket hög noggrannhet.Med hjälp av ett digitalt eldledningsstödssystem innehållandes en tredimensionell digital karta kopplat till EOI:et kan positionsfel i måluttaget i en urban miljö reduceras till under metern. .

Förklaringsmisstag : - i ett elektroniskt sammanhang

The thesis hears content-error in relation to agreements closed by electronic means. The purpose of the thesis is to elucidate how the rules in 32 §(1) AvtL apply to agreements closed by such means and to evaluate its suitability. The elucidation is done on the basis of, the rules? adequacy in relation to their objectives in collaboration with a comparative view on a selection of international legal framework under private law, such as DCFR, UNCITRAL Model Law, UNIDROIT Principles and CISG.Since Sweden lack a specific regulation for electronically closed agreements, all modern closing methods will be evaluated from the dated outlook of the Swedish Contract Act. In relation to entirely automated processes which results in the closing of an agreement, particular difficulty arise in correlation with prerequisites, which requires a human stance.

Prestandabaserad design genomkonceptuell energianalys : Performance-based design through conceptual energy analysis

This degree project aims to investigate the potential and possibilities for conceptual energyanalyses in the early stages of the design process. Many key decisions are made in theearly stages of a project regarding the shape and orientation of the building. Conceptualenergy analyses can provide the architects with insight regarding different design option?srelative energy performance.As the demands for more sustainable buildings increases, so does the need for earlyenergy analyses. Performing analyses in the early stage requires many assumptions andguesswork which could lead to a large margin of error.The offering from Autodesk is a module in Revit Architecture/MEP and the stand aloneprogram Project Vasari (under development).

Lotsbåtsolyckor : En studie om olyckor som involverar svenska lotsbåtar

Denna studie genomfördes i syfte att kartlägga och analysera mönster mellan olyckor sominvolverar svenska lotsbåtar. Studien utfördes som en kvantitativ litteraturstudie medkompletterande textanalys. Samtliga rapporter från lotsbåtsolyckor från de senaste 14 årenbegärdes ut från Transportstyrelsen. Dessa kategoriserades efter de vanligaste olyckstypernaoch analyserades därefter. Resultatet visade att flest olyckor sker i samband med transportenfrån kaj till fartyget som ska lotsas och vice versa, medan haverier och grundstötning är devanligaste incidenterna.

Aktiv förvaltning av fonder på Emerging Markets

The main purpose of this Master Thesis has been to evaluate whether active fund management is profitable on Emerging Markets. The material used to examine this consists of 106 actively managed funds, with varying length during the period 1988-2006 and who uses MSCI Emerging Markets (MSCI EM) as benchmark index. The thesis has been written under the supervision of the Asset Management Department of Länsförsäkringar AB (LFAB) and the Department of Production Economics, Linköping Institute of Technology. Apart from the main purpose, the methodology used is also meant to form a template for in-depth or similar studies, preferably by the assigner of this survey, LFAB.The results shows that the median manager underperforms the MSCI EM throughout the whole period, which leads to the conclusion is that active management on Emerging Markets is not profitable. A grouping of the funds based on tracking error still shows that a majority of the managers in all of the groups underperforms against the benchmark.

Vinkelfelet i mätkretsens påverkan på riktade jordfelsskydd

Utfört examensarbete undersöker vinkelfelet i mätkretsen för riktade jordfelsskydd och hur det påverkar dess felbortkoppling. Uppkomna vinkelfel i mätkretsen kan påverka det riktade jordfelsskyddet så att verklig felström och uppmätt felström inte stämmer överens, vilket kan leda till uteblivna eller obefogade felbortkopplingar. Vattenfall ställer krav på att vinkelfelet får uppgå till max ±2 grader för mätkretsen. Eftersom vinkelfelet i många fall har en hög påverkan på jordfelsskyddets noggrannhet undersöks vad Vattenfalls vinkelkrav egentligen innebär. Största orsaken till vinkelfelet uppstår oftast i strömtransformatorn och därför undersöks hur mycket två strömtransformatorer med olika klassificeringar som är vanliga i elnätet påverkar vinkelfelet i mätkretsen.Jordfel är det vanligast uppkomna felet i mellanspänningsnät och dess storlek beror till stor del på hur mycket kapacitivt bidrag som finns på linjerna samt värdet på nollpunktsresistorn.
