The content of this thesis is to research possibilities of using SNMP for management of Mobile IP activated entities. The first two chapters deal with theoretical analysis of Mobile IP protocol, and Simple Network Management Protocol. The Mobile IP protocol analysis focuses especially on the elements Home agent and Foreign agent. In the SNMP chapter the analysis focuses mainly on ways to exchange messages. Another part of the document is devoted to a description of laboratory networks com- posed of routers Cisco 1841 and the configuration of them. Finally is described the programmed application to manager these devices in JAVA, which is included in Annex. The program periodically sends SNMP queries and finds relationships between the Home agent and the mobile nodes, and between the foreign agent and the mobile nodes. The application has a user-friendly interface that is shown on the attached flash animation. Finally, the thesis summarizes the concepts described in previous chapters and the goals to achieve.

This paper presents a description of the IP Multimedia Subsystem (IMS) architecture and IMS services. IMS is a standardized next-generation networking architectural framework providing advanced services on mobile and fixed networks. The first chapter describes four-layer IMS architecture and also mentions supported services. The second chapter deals with IMS protocols and primarily focuses on the SIP signaling protocol. UDP, RTP and TLS protocols are also included in this chapter. The third chapter is dedicated to practical part of this paper. A VoIP Java application has been created based on the findings gained throughout the thesis. The main part of the created application consists of client-side application, database MySQL and Servlet application for communication between database and client-side application. The whole system was created using SDS Sony Ericsson 4.1. FD1. An OpenIC lite client has been tested during development on our system and results were compared with created client-side application. A web application based on PHP, MySQL and ActionScript then handles administration and monitoring of customers using voice services.

The goal of this thesis is to analyse communication possibilities between Java programming language and MATLAB enviroment and then to design and implementate a system using this communication. First of all this thesis focuses on overview and comparison of methods accesing MATLAB enviroment. In the next step there is a design of the system that mediates remote computations in MATLAB enviroment using the most effective method from previous step. Next chapter leaves a short description of Spring framework, which is used in implementation of application. The last step folows description of possibilities, instalation and configuration of the system.

In Java, there is empty space, which leaves here JEditorPane + HTMLEditorKit, meeting only HTML 3.2 and a subset of CSS 1. There are alternative solutions such as Lobo / Cobra Project, but mostly there are no signs of further development. CSSBox is (X)HTML/CSS 2.1 parser that is able to render the processed data as a simple bitmap image. Our goal is to design and later implement advanced graphical interface for CSSBox and try to fill the empty space.

The goal of this work is to allow JBoss ESB to communicate with remote applications using REST. JBoss ESB is a platform that separates application logic from the process functions and enables communication between applications with different interfaces by sending messages. REST is an architecture that provides universal interface for communication between computer systems in the network. This work describes integration of REST communication architecture with JBoss ESB platform. The integration is divided into two parts. The input part accepts REST requests, propagates their content to the JBoss ESB and generates a response. The output part waits for the messages from JBoss ESB from which it creates the REST requests, sends them to the recipients and receives responses. The implementation puts emphasis on integration with the RESTEasy project. RESTEasy provides a framework that facilitates development of applications that support REST communication.

The goal of this thesis is to explore the CSSBox experimental rendering engine, to explore the possibility of its expansion on incremental rendering of documents and then to propose the necessary modifications. The opening chapters contain an overview of existing possibilities and subsequently, the solution is proposed. The proposed changes are implemented and tested. Experiments were performed and results evaluated. The conclusion is dedicated to the evaluation of results and options for further development are outlined.

Utveckling av webbapplikationer ökar och flera ramverk skapas. Företag har idag möjligheten att välja bland tiotals ramverk att konstruera webbapplikationer. När ett koncept för en applikation framtas är inte samarbete mellan olika teknologier en stor prioritet. Fokuset ligger på konceptet av applikationen samt problemlösning som applikationen tillför. CSN har under det senaste året byggt en webbapplikation, vars huvudsakliga uppgift är att digitalisera pappersblanketter. Webbapplikationen har mycket utrymme för utveckling och idag står företaget framför ett stort problem. För att applikationen ska fungera som tänkt, krävs det ett samarbete med ett webbpubliceringssystem. Denna studie har utforskat de möjliga verktyg som finns idag för att kunna integrera en webbapplikation och med hjälp en komparativ analys kunde lämpligaste verktyg användas. Utöver detta gjordes en vidareutveckling på webbapplikationen. Syftet med denna vidareutveckling var att underlätta användarens ifyllande av blanketter. I samband med att automatisk ifyllnad av användardata funktionen utvecklades framkom behovet av ett varningssystem som kan varna CSN när ett formulär gör fel. Ett användbarhetstest utfördes som gav information kring hur väl resultatet från integrationen liknar det vanliga arbetssättet som används idag i webbpubliceringssystemet. Resultatet blev en fungerande integration, en ny komponent i CSN:s webbapplikation som hanterar det nya systemet för automatisk ifyllnad av användardata och ett varningssystem som varnar utvecklarna när olika formulär hittar fel. Resultatet på användbarhetstesterna var positivt. Flera andra myndigheter har fått reda på vad CSN:s applikation har för möjligheter och deras intresse i digitalisering av blanketter har ökat. Detta är något som kommer ge en positiv inverkan på miljön och myndigheternas ekonomi. / The development of web applications has increased in popularity and more frameworks are created. Companies today can choose between a multitude of different frameworks to construct their web application. When an application concept is made the focus is not on the application's ability to integrate with other systems. The focus in development is in the concept of the application and the problems the application will solve. CSN has during the last year developed a web application with the primary focus of digitizing application forms. The application has room for more development and today the company stands before a difficult task. The application needs to work with the company’s content management system. This study has explored the possible tools that exist today for integration with web applications. With the help of a comparative analysis a suitable tool was found. Beyond the integration further development of the application was made. The purpose of this development was to make it easier to fill out these forms. In conjunction with the development of the autofill function the project group deemed it necessary to develop a warning system. This system will warn the developers at CSN when a form encounters an error. A usability test was performed to gather information about how familiar the result integration was to the normal workflow. The result is a successful integration, a new component in CSN’s application to handle the new system for prefilling data and a warning system to warn the developers and to show error logs that is produced when an error occurs. The result of the usability test was positive. Other authorities have heard of the possibilities of CSN’s application and their interest in digitalizing forms have increased. This is something that will have a positive impact on both the environment and the authority’s economics.

This research develops an object-oriented approach to model airport ground network traffic operations. A generic modeling library is developed as a tool kit to model the basic traffic operations in the airfield using an object-oriented approach. The proposed generic modeling library for airfield operations is a collection of predefined abstract components implemented in the Java object-oriented programming language. Classes are defined and used as the basic components in a variety of airfield operation modeling, simulations, and optimizations. The generic airport modeling framework consists of a set the components that are necessary for modeling the basic activities of airfield traffic operations. By using the multi-threading techniques, components are integrated into the proposed modeling framework. Unlike traditional sequential simulation model, this framework organizes simulation activities into four major groups which are: flight schedule, aircraft movement, time, and animation. Instead of using built-in control logic, the framework adapts an open system policy which gives the flexibility to the end users to incorporate the user-preferred control logic into the end models. Another purpose in this research is to provide a future mechanism to study airfield ground traffic automated control systems with Just-In-Time forecasting and model system performance in a real-time ATC environment. The proposed generic library could be implemented into a Internet/intranet ready application which can query real time information and provide real time advice to pilots and air traffic controllers. This study is one of a few current research projects that are of using multiple threading technique to study traffic operation problems. The proposed generic library is originally implemented with C++ and, in the final stage, with Java, a truly cross-platform object-oriented language. Application written in Java can run on most of the mainstream computer operating systems without modifications. Although the proposed library is for airfield traffic control system, it could also be extended into air traffic control system as well as advanced transportation system. / Ph. D.

This master thesis project took place at Orc Software. This company provides technology for advanced trading, market making, and brokerage. The Orc System is based on a client/server architecture. The ordinary way to communicate with the Orc Server System is via the Orc Client Applications, such as Orc Trader or Orc Broker. Additionally, there is another way to communicate with the Orc Server System without using an Orc Client Application. There is a service within the Orc Server System which provides an interface for communication with the Orc Server System. Clients can communicate via this interface using the Orc Protocol (OP). Banks and brokers usually have different systems that are specialized for different needs. Often there is a need to integrate these systems with the Orc Server. In order to simplify the integration for customers with modest programming experience in TCP/IP and parsing techniques, Orc Software would like to provide an example parser/generator capable of communication with the Orc Server System free of charge. This thesis introduces a toolkit consisting of a parser/generator and a sample application. The application provides several examples as well as serves as verification to the customers of how simple it is to develop their own applications by utilizing the different OP messages. A comparison was made between the newly created OP parser/generator and a manually generated FIX client using the FIX gateway which ORC Software AB also sells. This evaluation shows that OP parser/generator is both faster and less memory demanding than the manually generated FIX client. / Det här examensarbetet är utfört på Orc Software, som utvecklar system för avancerad handel, market making samt mäkleri. Detta system är baserat på en klient/server arkitektur. Normalt sker kommunikationen med Orc Servern via Orc klient applikationer som Orc Trader eller Orc Broker. Men det finns även ytterligare ett sätt att kommunicera med Orc Servern utan att använda Orc klient applikationer. Det finns en tjänst i Orc Servern som tillhandahåller ett gränssnitt som går att kommunicera med genom att använda Orc Protocol (OP) meddelanden. Banker och mäklare har vanligtvis flera olika system som alla är specialiserade för olika behov. Detta gör att det ofta finns ett behov att integrera dessa system med Orc Servern. För att kunna underlätta integrationen för kunder med låga kunskaper i TCP/IP och parsing teknik, vill Orc Software tillhandahålla en gratis parser/genererare som kan kommunicera med Orc Server Systemet. Examensarbetet introducerar ett paket innehållande en parser/genererare och ett exempelprogram. Programmet visar ett par exempel samt fungerar som bekräftelse på hur enkelt det kan vara att utveckla ett eget program som använder sig av del olika OP meddelanden. Avslutningsvis presenteras en utvärderingsstudie mellan den utvecklade parser/generator och en manuellt genererad FIX klient som använder en FIX gateway som Orc Software också säljer. Utvärderingen visar att parser/genereraren är både snabbare och använder mindre minne än FIX klienten.

At ITICSE 2002, the Lego Working Group first outlined how the Robots can be used to teach CS1 using Java. It was decided that a special session at SIGCSE 2003 designed to collect "best assignments" would simplify highlighting the benefit of using Robots to teach CS1. The creator of the assignment judged to be best would then be awarded a LEGO MINDSTROMS:Robotics Invention System 2.0 that will be provided by Sun Microsystems.
