Inom styr- och reglerteknik är hantering av larm en viktig fråga, speciellt då fastighetsbranschen mer och mer börjat automatisera driften av fastigheterna. Det finns ett antal system på marknaden som erbjuder larmdistribution via en mängd olika transportsystem. Syftet med projektet är att undersöka om det finns alternativ till dessa som erbjuder mer flexibilitet, samt att designa en prototyp till ett system som använder denna alternativa metod. Två befintliga system analyserades och en kravspecifikation baserad på analysen upprättades. Utifrån denna designades en prototyp som sköter distributionen över Internet och en enkel Implementation av en del av designen har gjorts.

Minskad effektförbrukning har blivit mer och mer intressant i takt med att fler produkter blir mobila. I artikeln Parallel Implementation of Linear Feedback Shift Registers for Low Power Applications, beskriver Menahem Lowy en metod för att konstruera slumptalsgeneratorer. Dessa är tänkta att vara effektsnålare än en vanlig enkel slumptalsgenerator, med återkopplat skiftregister. I det här examensarbetet har sex slumptalsgeneratorer konstruerats i VHDL. Två är baserade på Lowy?s metod och två är parallella varianter av dessa.

Aligning parallell terms in a parallell corpus can be done by aligning all words and phrases in the corpus and then performing term extraction on the aligned set of word pairs. Alternatively, term extraction in the source and target text can be made separately and then the resulting term candidates can be aligned, forming aligned parallell terms. This thesis describes an Implementation of a word aligner that is applied on extracted term candidates in both the source and the target texts. The term aligner uses statistical measures, the tool Giza++ and heuristics in the search for alignments. The evaluation reveals that the best results are obtained when the term alignment relies heavily on the Giza++ tool and Levenshtein heuristic..

This report describes how the process has evolved during the creation of a new web page forthe company Scandinavian Travel Agent DMC. The design methods that have been used aredescribed and also how parts of the webpage have been created by using the design methodresults. Our reflections around design and functionality are explained and how usability hasbeen our main focus during the master thesis. We also describe how it has been to work withan external costumer and how the tasks constantly have changed and been added as theprocess has continued.The background to this work is that AB Scandinavian Travel Agent DMC need to improve theircurrent web page. This to give the clients better needed information about destinations, butalso to stand out in the competitive travel business.

Gender politics in Sweden is considered unique because gender policies (jämställdhet) are integrated into national politics and politicised both in the public and the private sphere. The Swedish case is therefore considered a role model by many feminist scholars.This view has been criticised by both post modern feminists and public administration scholars. Critics imply that the increased immigration and more heterogeneous population have led to a new challenge for state institutions. The Swedish model, with its universal welfare solutions, lacks the ability to recognise differences within groups. Universal solutions that treat everyone the same is no longer the most just way to treat people.The growing use of goal orientation in Swedish public administration has increased the civil servants discretion in the Implementation process, and thereby the space for differentiated treatment.

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++. The algorithm is developed by Sasan Gooran, who is our examiner in this project. The algorithm uses an iterative method to produce the halftoned images. The reason for this project is to speed up the existing program which is made in Matlab.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code Implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Rapporten tar upp och behandlar ämnet betalväxlar utifrån en utvecklares perspektiv. Två företag som varit i eller nära inpå processen att utveckla en webbshop har intervjuats och jämförts med utbudet hos ett antal olika betalväxlar. Intervjuerna har visat ett resultat som är mycket troligt att man som ny utvecklare kommer i kontakt med i början. Positionen kan då vara både som utvecklare eller som ägare till webbshoppen. Det gick även att konstatera att det fanns ett antal betalväxlar lämpade för olika kunskapsnivåer.

Detta examensarbete har haft som uppgift att undersöka möjligheterna för hur man skulle kunna förbättra gränssnittet för användarna av WIS, Webbaserat informationssystem (1), genom att göra webbapplikationerna mindre dataintensiva. Examensarbetet görs i samarbete med Know IT Candeo AB i Luleå som är utvecklare och förvaltare av systemet. Examensarbetet tar upp några exempel på hur många webbapplikationer fungerar och är uppbyggda idag och försöka se det från ett perspektiv på hur man skulle kunna förbättra gränssnittet för användarna med hjälp av asynkron webbkommunikation. De bakomliggande principerna för asynkron webbkommunikation kommer att behandlas för att sedan kunna beskrivas mer specifikt i AJAX(Asynchronous JavaScript and Xml) tekniken och Microsofts Implementation av AJAX som heter ASP.NET AJAX (3). För att kunna utvärdera om asynkron webbkommunikation är användbart i just detta specifika projekt ska några enkla prototyper tas fram..

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe Implementation of eight measurement circuits in the system.

In today's social work there is an ambition to work evidence-based in order to improve quality and competency in business. This study is made in a disability administration which has introduced a common approach towards users for all employees. The approach is called low arousal approach. The purpose of the study is to investigate how a method takes hold and implements within an organization. The empirical data is analyzed by theories of professionalization, idea dissemination and translation.

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and Implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different Implementations often results in different VaR forecasts. An interesting Implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.
