The project is to design and implement a Web application for realizing an innovative, hands-on interactive learning experience for the Google Maps API. This learning environment was developed based on a real-world Geographic Information System (GIS), the Gulf of Mexico Coastal Geospatial Information Support System. Significant efforts were invested not only in development of this GIS system, but also in the design and implement that turns the production system into a learning environment. The Web development aspect attracts computer science students, while the opportunity to learn GIS concepts in an interactive way to attract students from the geography department and the opportunity to learn the Google Maps API proves interesting to regular internet users. The Web learning system was given to a focus group whose feedback was collected through a survey. The survey results reveal a favorable response to the interactive, hands-on learning model and the Web implementation.

Scripting, defined as the mechanization of business processes through automated tools or orchestrated responses, has played a significant role in shaping call center activities and the resultant customer relationship. However, findings of industry research have shown that the use of scripting to maximize operational efficiency has had a disempowering effect on call center employees by lowering their job-skill and knowledge requirements. Grounded in the concepts of knowledge management and knowledge transfer, this study explored the experiences of frontline call center employees on the effects of scripting on customer problem solving. A single-case study design with semistructured interviews was used with a population of 20 frontline employees in a North American call center to gather insights. Thematic analysis was applied to the interview data using nodes to identify emerging themes and insights. Three major themes emerged: First, although scripting had contributed to improved service quality and operational efficiency, scripted practices undermined the use of team knowledge and limited the amount of shared information. Second, the employees requested that call center scripted solutions be more intuitive and better aligned to knowledge requirements. Third, the employees suggested that an object-oriented approach to solution management be used, one that could better leverage communities of practices and collective team knowledge sharing within the organization. This object-oriented approach to solution management may promote virtual knowledge flow and the building of subject matter expertise that could elicit higher agent engagement and problem ownership. The proposed object-oriented approach to knowledge sharing is important to management, as it could help facilitate knowledge reuse and improved organizational performance.

<p>Skriptspråk har under det senaste decenniet fått en ökad spridning, både gällande användare</p><p>och gällande användningsområden. Från att huvudsakligen ha använts till enklare dagliga</p><p>administratörsuppgifter används idag skriptspråken inom många områden där tidigare enbart</p><p>systemspråk var ett alternativ. Denna uppsats undersöker och granskar fem skriptspråk: PHP,</p><p>Perl, Ruby, Tcl och PostScript. Målet är att undersöka språkens egenskaper och se på</p><p>skillnader språken emellan. Vi jämför också skriptspråken mot systemspråket C, som dock</p><p>inte granskas för sig. Vi utför ett test där quicksort-algoritmen används för att sortera ett antal</p><p>element som läses in från fil. Ett testskript skrivs i varje språk, och dess effektivitet och</p><p>expressivitet jämförs.</p><p>Vi kommer i denna uppsats fram till att definitionen för skriptspråk, och det som skiljer</p><p>skriptspråk från systemspråk, är skriptspråkens avsaknad av ett separat kompileringssteg. En</p><p>annan viktig aspekt är skriptspråkens användning av dynamisk typbindning för variabler. De</p><p>tester vi gjort visar att inget av skriptspråken kan mäta sig med systemspråket C vad gäller</p><p>exekveringstid, däremot är de bättre gällande expressivitet. Av skriptspråken är Perl det språk</p><p>som är snabbast och PostScript det språk som är långsammast.</p> / <p>During the last decade, scripting languages have seen an increase in both number of users and</p><p>areas of development.

Augmented Reality (AR) is a technology which blends virtual and real worlds. The technology has various potential application domains such as broadcasting, architecture, manufacturing, and entertainment. As the tempting developments in AR technology continues, the solutions for rapid creation of AR applications become crucial. This thesis presents an AR application development framework with scripting capability as a solution for rapid application development and rapid prototyping in AR. The proposed AR framework shares several components with game engines. Thus, the framework is designed as an extension of a game engine. The components of the framework are designed to be changable in a plug-in system. The proposed framework provides the developers with the ability of agile coding through the scripting language. Our solution embeds a dynamic scripting programming language (Python) in a strictly typed static programming language (C++) in order to achieve both agility and performance. The communication between the AR framework components and the scripting programming language is established through a messaging mechanism.

Today, interoperability is the major challenge for e-Business and e-Government domains. The fundamental solution is the standardization in different levels of business-to-business interactions. However publishing standards alone are not enough to assure interoperability between products of different vendors. In this respect, testing and certification activities are very important to promote standard adoption, validate conformance and interoperability of the products and maintain correct information exchange. In e-Business collaborations, standards need to address different layers of interoperability stack / communication layer, business document layer and business process layer. Although there have been conformance and interoperability testing tools and initiatives for each one of these categories, there is currently no support for testing an integration of the above within a test scenario which is similar to real life use cases. Together with the integration of different layers of testing, testing process should be automated so that test case execution can be done at low cost, and repeated if required. In this theses, a highly adaptable and flexible Test Execution Model and a complementary XML based Test Description Language consisting of high level test constructs which can handle or simulate different parts or layers of the interoperability stack is designed. The computer interpretable test description language allow dynamic set up of test cases and provides flexibility to design, modify, maintain and extend the test functionality in contrast to a priori designed and hard coded test cases. The work presented in this thesis is a part of the TestBATN system supported by TUBITAK, TEYDEB Project No: 7070191.

Ziel der Arbeit war es, eine Client-Server-basierte Loesung zu entwickeln, welche eine Backupfunktionalitaet in einer heterogenen Workstationumgebung mit dezentralen Filesystemen bereitstellt. Das System sollte mit Hilfe einer Scriptsprache implemetiert werden, um die Systemunabhaengigkeit der Komponenten zu gewaehrleisten. Zu diesem Zwecke wurde als Grundlage das ¨Remote Scripting Environment¨, welches Gegenstand der Diplomarbeit von Andre Glaesz am Lehrstuhl Betriebssysteme war, gewaehlt.

This is a Masters Thesis report of a project carried out at Scania AB in Södertälje. The project concerns rationalizing Chassis calculations for use in truck Frame design. The subject for analysis is a six-wheeled articulated truck, and the load cases under study is Lateral Loading, Frame Torsion and Vertical Load on Kingpin. Making robust deformation and stress models with a calculation time sufficiently short and accuracy consistently high for efficient design work is an arduous task. This report presents several approaches to tackle this type of problem. By means of simplifying contemporary modeling approaches and methods and automating the setup process, a method that enables short calculation iterations on a chassis frame of a truck is achieved. This is done using the Catia GAS framework in conjunction with several other licences commonly used by designers.

It is difficult to develop a program that is completely free from vulnerabilities. Despite the applications of many approaches to secure programs, vulnerability exploitations occur in real world in large numbers. Exploitations of vulnerabilities may corrupt memory spaces and program states, lead to denial of services and authorization bypassing, provide attackers the access to authorization information, and leak sensitive information. Monitoring at the program code level can be a way of vulnerability exploitation detection at runtime. In this work, we propose a monitor embedding framework DESERVE (a framework for DEtecting program SEcuRity Vulnerability Exploitations). DESERVE identifies exploitable statements from source code based on static backward slicing and embeds necessary code to detect attacks. During the deployment stage, the enhanced programs execute exploitable statements in a separate test environment. Unlike traditional monitors that extract and store program state information to compare with vulnerable free program states to detect exploitation, our approach does not need to save state information. Moreover, the slicing technique allows us to avoid the tracking of fine grained level of information about runtime program environments such as input flow and memory state. We implement DESERVE for detecting buffer overflow, SQL injection, and cross-site scripting attacks. We evaluate our approach for real world programs implemented in C and PHP languages. The results show that the approach can detect some of the well-known attacks. Moreover, the approach imposes negligible runtime overhead. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2011-09-19 19:04:28.423
