<p>The aim of this thesis is to develop an technical aid (software) to help people with colourblindness. Colour blind people have difficulties to differentiate between certain colours,so the implemented software will name a selected colour. The software is implementedas a Mozilla Firefox extension and also uses a XPCOM component. Furthermore canthe user select different colour databases and change the displaying properties.The aim of this thesis is to develop an technical aid (software) to help people with colourblindness.

This term project deals with digital forensic analysis of web browsers. The first chapters describe the process of forensic analysis, methodologies and procedures used, and also the issues of analysis of web browsers. In particular, the types of information browser stores and security problems that comes with that. Theoretical and practical procedure for obtaining data from Mozilla Firefox web browser was based on the theoretical foundations described in previous chapters. Common linux tools and application created as part of this thesis are used in process of collecting digital evidence. Digital forensic analysis of web broewser was performed based on suggested procedure.

This master thesis deals with the topic of browser extensions, their environment and analysis. The goal is to describe the extensions environment, online Webstores, that offers extensions and to show best practices for analysis and optimization of its extensions and their assets. Within the thesis you can find very precise analysis of online Webstores for Google Chrome extensions and Mozilla Firefox add-ons. Conclusions are made based on this analysis that include special characteristics of the previously mentioned browsers. The master thesis consists of two parts, theoretical and practical. The theoretical parts deals with the description of the browser extensions environment and it presents specific characteristics about online Webstores and browser extensions to the reader. In the practical part the thesis is focused on objectives set by the thesis and it presents the results of the Webstore analysis and description of the universal Google Analytics solution that helps developers to analyze their extensions The thesis contributes to the topic mainly with the precise description of the browser Webstores and extensions environment, best practices and recommendations and by creating the universal Google Analytics solutions for the developers.

This thesis was created as a helping tool to estimate the price of properties by comparative method, which needs a database of properties. This database is created by a program. The main aim of this thesis is to create an application in Python language, which will search through contents of websites of a chosen real estate portal in Czech Republic. The next aim of this thesis is to create program which will search for real estate according to chosen criteria. The purpose of these criteria is to compare and estimate the price of properties. In the theoretical part of this thesis I will describe data mining and architecture of data mining. In the practical part I will design an aplication and in the end I will implement it. This aplication will go through websites and obtain data about real estate offices, their advertisements and photos of advertisements. For easier work with the output file that contains the advertisements, I created an application for searching individual advertisements based on users specification. This program allows to quickly search for the requested data from the output file. These data are subject to further work, it is possible to analyse them and create interesting statistics and maps.

<p>Under 1990-talet utspelade sig en bitter kamp om marknadsandelar mellan de två ledande webbläsare Internet Explorer och Netscape Navigator, det så kallade webbläsar-kriget. Kriget hade till följd att webbläsarna blev nästan helt inkompatibla. Sedan dess pågår en ständig utveckling av gemensamma standarder för webben. Idag är förutsättningarna för kompatibilitet mycket bättre än för tio år sidan, men problemet är inte fullständigt avhjälpt. De moderna webbläsare Internet Explorer 6, Firefox 1.5, Opera 8.5 och Safari kan återge en och samma webbsida visas på olika sätt trots att det finns gemensamma standarder. Syftet med denna uppsats är att ta reda på de tekniska orsakerna bakom problemet samt att ta fram lösningsförslag för att skapa en webbsida som är helt kompatibel i de moderna webbläsarna. Uppsatsen innehåller ett omfattande teorikapitel som behandlar definitioner, historik och problem. Teorin kompletteras av tre fältintervjuer med professionella webbutvecklare. Undersökningarna visar att kompati-bilitetsproblem beror på flera faktorer och att det är omöjligt att skapa en heltäckande lösning som kommer åt alla problem. Men genom att kombinera olika tekniker kan man skapa en metod som täcker en stor del av såväl generella som specifika kompatibilitetsproblemen utan att kollidera med rekommenderade standarder.</p> / <p>During the 1990’s the two leading web browsers, Internet Explorer and Netscape Navigator, fought each other in a battle for market shares, the so-called browser war. This war caused almost complete incompatibility between the web browsers. Since then, there has been a continual development of common standards for the web. Today conditions for compatibility are a lot better compared to ten years ago, but the problem is not completely solved. The modern web browsers Internet Explorer 6, Firefox 1.5, Opera 8.5 and Safari can display the exact same web page differently despite common standards. The aim of this essay is to investigate the technical causes of the problem and to develop suggested solutions for creating a web page that is fully compatible in modern browsers. The essay contains an extensive literature study, considering definitions, history and problems. The theory was completed with three field interviews with professional web designers. The investigations show that compatibility problems depend on several factors and that it is impossible to create one exhaustive solution that encompasses all problems. However, by combining different techniques one can create a method that covers a large part of both general and specific compatibility problems without colliding with recommended standards.</p>

In software development projects, bug triage consists mainly of assigning bug reports to software developers or teams (depending on the project). The partial or total automation of this task would have a positive economic impact on many software projects. This thesis introduces a systematic four-step method to find some of the best configurations of several machine learning algorithms intending to solve the automatic bug assignment problem. These four steps are respectively used to select a combination of pre-processing techniques, a bug report representation, a potential feature selection technique and to tune several classifiers. The aforementioned method has been applied on three software projects: 66 066 bug reports of a proprietary project, 24 450 bug reports of Eclipse JDT and 30 358 bug reports of Mozilla Firefox. 619 configurations have been applied and compared on each of these three projects. In production, using the approach introduced in this work on the bug reports of the proprietary project would have increased the accuracy by up to 16.64 percentage points.

The aim of the thesis was to design, implement and evaluate the results of automatic tests for the JavaScript Restrictor project, which is being developed as a web browser extension. The tests are divided into three levels - unit, integration, and system. The Unit Tests verify the behavior of individual features, the Integration Tests verify the correct wrapping of browser API endpoints, and the System Tests check that the extension does not suppress the desired functionality of web pages. The System Tests are implemented for parallel execution in a distributed environment which has succeeded in achieving an almost directly proportional reduction in time with respect to the number of the tested nodes. The benefit of this work is detection of previously unknown errors in the JavaScript Restrictor extension and provision of the necessary information that allowed to fix some of the detected bugs.
