Grafisk utvecklingsplattform för signalbehandling - Design och implementation

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.

Risk management i läkemedelsindustrin : Hur användbara är optimeringsmodeller vid urval av projektportföljer?

Risk management har historiskt sett associerats med riskminimering och undvikande. Men framför allt inom project portfolio management har ett skifte inletts mot ett proaktivt tillvägagångssätt för att hantera risk, snarare än reaktivt. På så sätt uppnås en holistisk analys av risk som tar hänsyn till både positiva och negativa avvikelser på mål. Syftet med detta arbete är att undersöka hur användbara optimeringsmodeller är i läkemedelsindustrin ur ett risk management-perspektiv. Modellerna som undersöks är capital budgeting problem, goal programming och contingent portfolio programming.

PixelCity Sharp-X : Jämförelser ur utvecklarperspektiv mellan C++ med OpenGL och C# med Direct3D

This essay serves to illustrate the main practical differences between the popular medium-level programming language C++ (C Plus Plus), and the newer high-level language C# (C Sharp). It will focus on the aspects that are readily apparent to the application programmer, such as differing syntax, constraints and capabilities.It will also feature a similar comparison between the open source OpenGL graphics library, and the proprietary Direct3D graphics library owned by Microsoft Corporation.It will not go into the differences in ?under the hood? mechanics that the application programmer seldom have to consider after having chosen his programming language or graphics API, such as C# being compiled into an intermediate language and is run on a virtual machine where C++ is compiled directly to machine code, or the differing principles of rendering in OpenGL and Direct3D.This is by no means comprehensive, many things have been left out or overlooked..

En undersökning av faktorer som styr valet mellan XP och RUP

För att genomföra ett lyckat systemutvecklingsprojekt kan ett flertal utvecklingsmetoder användas. Utvecklingsmetoder hjälper till att undvika fallgropar under utvecklingsprocessen. De två typer av utvecklingsprocesser som arbetet baseras på är eXtreme Programming (XP) och Rational Unified Process (RUP).Genom att identifiera skillnader samt hur XP och RUP kan kombineras, presenteras olika faktorer. En faktor är projektstorlek som enligt litteratur är den viktigaste faktorn vid valet mellan XP och RUP. Med hjälp av en enkätundersökning hos ett antal utvecklingsföretag har data samlats in för att ta reda på om projektstorlek är en huvudsaklig faktor för valet mellan XP och RUP.

The study part consists of examining and comparing different data acquisition systems for testing of different circuit boards, taking into account the modularity, real-time applications, mobility, environmental, interface hardware and software, to be able to define a general module-based data acquisition system in both hardware and software that enables for future developments.The programming part consists of getting started with Visual Studio, which integrates the Measurement Studio for C#. NET. Measurement Studio includes classes and user controls for testing and measuring and offers tools for acquisition, analysis and presentation of real world data.

MyMusic ? e-shop för musik i Flash

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

HEJO MAIL : HTML och CSS för email

?HEJO MAIL ? HTML och CSS för email? handlar precis som titeln antyder om användandet av HTML och CSS för att utforma e-postmeddelanden och är en undersökning över vilka standarder som finns eller åtminstone borde finnas. Viktiga fraser vid informationssökningen har varit ?Html Email?, ?Email Standards? och ?Email Programming?. Resultatet är tänkt att appliceras på HEJO MAIL, som är en applikation för utskick av nyhets- och informationsbrev som idag inte fungerar fullt ut.Resultatet är något förvånande då standarder specifikt för email saknas och har ersatts med rekommendationer, resultatet innefattar en sammanställning av rekommendationer från tre olika källor som valts ut.

Har dagens gymnasieelever nytta av sina datakunskaper på högskolenivå. : Får dagens elever arbete på sina gymnasiebetyg inom de nya Data/IT programmen

The purpose is to analyze if the students have any use of their computer education at a senior high school level or if there is a demand for them to proceed studying. Does the students background have any importance or is it their own motivation that makes the student advance to higher education.In this report we ask ourselves the question, if the students have any use of the knowledge gained at senior high school in computer studies at a higher level. Do the students have any chance for employment based on their senior high school grades in computer studies after graduation?  Do the schools that follow the senior high school guidelines within programming and databases give these students an advantage towards those that have not received the same fundamental education?The method used for the survey is a group questionnaire.  The questionnaire was distributed at one and the same time and then collected to examine the results. The survey results showed that students who seek work based only on their senior high school grades, received only a temporary position for different lengths of time.

Framtagande av kravspecifikation för standardsystem

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

Konstruktion av en autonom vindstation

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

Simulation driven design : An iterative approach for mechanical engineerswith focus on modal analysis

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

Logicat

I vår produktion har vi tagit fram ett system för order- och lagerhantering, med vikt på realtidsuppdateringar, åt en extern mottagare där infrastrukturen inte hängt med i företagets utveckling. Vi valde detta projekt i syfte att bredda våra kunskaper inom både programmering och projekthantering. Denna slutreflektion tar upp den förundersökning vi gjorde för att kunna besluta om vilka verktyg vi använde i utvecklingen, den tar även upp vårt sätt att hantera och planera projektet. Under projektet har vi arbetat med en egenutformad arbetsprocess vilken även beskrivs här. --- Our production has been to design a system for ordering and supply management with emphasis on realtime updates to an external recipient, where the infrastructure has not kept pace with the development of the company.
