Šio darbo tikslas – sukurti efektyvius įvykių atpažinimo filtrus duomenims, gautiems pasitelkiant pagreičių matavimo prietaisus mobiliosiose technologijose. Atlikus sukurtų filtrų nuodugnius tyrimus įvertinti, kurie iš filtrų įvykius atpažįsta efektyviausiai. Neuroninių tinklų pagalba išskirti duobę ir greičio ribojimo kalnelį iš bendro įvykių srauto. Sukurtą prototipą realizuoti praktiškai ir išsamiai atvaizduoti gaunamus rezultatus. Taip pat susipažinti su kitų autorių sukurtais atpažinimo modeliais bei sistemomis, palyginti jų sukurtų algoritmų bei šio darbo atpažinimo rezultatus, praktiškai realizuoti išnagrinėtą modelį. Užfiksuotoms eismo įvykių koordinatėms pritaikyti tinkamiausią duomenų grupavimo algoritmą ir išsamiai atvaizduoti gautus rezultatus. / The aim of this work was to analyze the data which was gotten from accelerometer mounted in mobile device during the test drives through the city together with GPS (Global Positioning System) coordinates, to detect and report the surface conditions of roads as well as to find the way, how it could be represented in the map. The research was started by analyzing oscillation data from accelerometer. We had to keep in mind that there can be road bumps, pit holes, speed bumps and other road anomalies, car can accelerate quickly and break sharply or even crash into something, what would cause a sudden stop. In order to recognize events, different detection filters were applied on data. In addition to this, neuron network was used to recognize pit holes and speed bumps from all event flow. The results of event detection algorithms were compared with other scientist’s works. In order to represent results clearly, database was created holding coordinates of the road events and other information like time, etc. The results were represented using an application programming interface made-up by Google, which was really suitable solution in our case. The whole system was programmed using Java servlets, which allowed to gather data from database using SQL (Structured Query Language) queries. While trying to represent accelerometer data, we faced difficulties in representing these road events on the map, as GPS each time returned answer with small variation of coordinates. In this case, we... [to full text]

Vi har utvecklat två fristående webbapplikationer till det webbaserade hälsovårdsstödsystemet Asynja. Den ena är en designapplikation för enkätundersökningar och den andra är en svarsapplikation där respondenterna kan besvara enkäterna. Utvecklingsprocessen har bestått av planering, design, implementation, testning och dokumentation. Mycket av arbetet har skett parallellt vilket vi har sett som en framgångsfaktor i examensarbetet. Projektet har präglats av att applikationerna ska vara användarvänliga och funktionella samtidigt som designen och koden ska göra att applikationerna kan vidareutvecklas och underhållas effektivt. Arbetet med att utveckla J2EE-applikationer och använda sig av ramverket Struts har gett goda erfarenheter och det har även visat sig att denna plattform är väl lämpad för denna typ av uppgifter.

Creating websites providing dynamic services is an extensive process. Intelligent systems are used to create websites with dynamic services. Current intelligent systems are hard to use and configure by the average user. The generated websites are usually custom built to solve one problem and cannot be fully customizable for users on different environments. This thesis presents a technological solution that enables the average user to create websites with dynamic services by providing a number of parameters. The website generator is a web-based application that generates all the components of the website. The components act as portlets and the generated website will be the portal application. The data engine generator creates the website's underlying database. To enable distributed enterprise/business architecture, the data engine generator records the metadata about the database and the website to be generated. The website generator is a cost effective, dynamic, secure, reliable, and scalable solution that outperforms current website generators and portal applications.

This master's thesis is engaged in concept and creation of web application's graphics user interface. The reason is to convert a classic application written in Java language to the web form by force of JSP and AJAX technologies.
