The subject of this Master’s thesis is focused on an analysis of promotional agency’s requirements concerned with producing a bespoke Information System. The subsequent evaluation of the current situation becomes together with a result of the analysis of requirements a relevant foundation in formulating a scheme for the solution and for the realization of the Information System.

The usability of web applications today often suffers from the page-based medium’s lack of intrinsic support for hierarchical dialog sequences mirroring the parent-child relationships between dialog boxes in window-based user interfaces. For multi-channel applications, an additional challenge lies in reconciling the device-independent business logic with the device-specific interaction patterns necessitated by different clients’ input/output capabilities.We therefore present a graphical Dialog Flow Notation that allows the specification of nestable dialog sequences for different presentation channels. These specifications serve as input for a Dialog Control Framework that controls the dialog flows of complex web applications.

Introductory computer science courses can be notoriously difficult for students, especially those outside of the major. There are many reasons for this, but the programming software itself may play a significant role.  To address this issue, we have developed Pythy, a web-based programming environment that allows students to write, execute, and test programming assignments from within the familiar interface of a web browser.  In this work, we discuss various aspects of Pythy in detail, including the rationale behind its design, the system architecture on which it is built, and the various functions offered by the software.  Next, we discuss an evaluation of Pythy\'s effectiveness during a programming course for non CS-majors offered at Virginia Tech, comparing it to a different software solution used in another programming course.  Results suggest that Pythy was successful in several target areas, including making it easier to get started with programming and providing feedback about program behavior.  Access log data from Pythy itself reveals details about how students used the system.  Finally, we conclude with a summary of key contributions and suggest some potential future directions for the system. / Master of Science

The purpose of this project was to determine how the experienced navigability of a web application affects its usability. In order to further investigate this, a web application called Sprouty was created, an easy-to-use web application that promotes individuals to buy and sell pre-owned plants and cuttings. The reasons for choosing this business concept are rooted in the marketing surveys that were first conducted before the webpage was developed. The results from this survey showed that there was a high demand among individuals to be able to buy plants online. This segment had previously been trading and selling plants through online social platforms such as Tradera, Blocket and Facebook Marketplace and sought a more structured platform to conduct these activities. Throughout the development of the web application, theories have been applied from peer reviewed articles regarding subjects such as layout, design, navigability and consumer behavior. To later test the efficiency of these theories and tools, two iterations of user tests were conducted by using the methods Lostness and Think aloud. In addition to this, a questionnaire was used for both tests. After the first iteration of user tests had been conducted, changes were made according to the feedback received in order to improve the user experience and the applications over- all functionality. To test the impact of these improvements, another round of user tests were conducted in order to measure how the changes impacted the navigability and experienced usability. The results showed that having a search engine, filter function and theory based layout improved the navigability of the "Shop" page of the web application. Lastly, the re- sults showed that having an intuitive design similar to other known websites is important to minimize confusion when performing tasks. This lead to the conclusion that the overall web application’s layout, design and filter functions all are important aspects impacting the experienced navigability and therefore the usability of the web application. / Syftet med detta projekt var att avgöra hur den upplevda navigerbarheten av en web- bapplikation påverkar sidans användarvänlighet. För att undersöka detta skapades en hemsida som heter Sprouty, en sida där privatpersoner enkelt kan köpa och sälja plantor och sticklingar. Affärsidén grundar sig i en marknadsundersökning som gjordes innan webbapplikationen utvecklades. Resultaten från undersökningen visade att det fanns en hög efterfrågan hos individer att ville köpa och sälja växter och sticklingar online. Mål- gruppen inom detta marknadssegment har tidigare använt plattformar såsom Tradera, Blocket och Facebook Marketplace och har därför efterfrågat en mer strukturerad plattform för att tillgodose dessa behov. Genom hela utvecklandet av webbapplikationen, har teorier från vetenskapliga artik- lar applicerats, vars innehåll berör ämnen såsom layout, design, navigerbarhet och kon- sumentbeteende online. För att senare testa effektiviteten hos dessa teorier och verktyg ut- fördes två iterationer av användartester med metoderna lostness och think aloud. Utöver detta fick testpersonerna från båda undersökningarna svara på en enkät efter att testen utförts. Efter första iterationen av testernagjordes förbättringar kopplat till de resultat som hämtades från användartesterna. För att undersöka vilken påverkan förbättringarna hade gjordes sedan en till omgång användartester för att mäta vilken effekt förbättringarna hade på navigerbarheten och den upplevda användarvänligheten. Resultaten visade på att en sökmotor, filterfunktion och en väl genomtänkt layout förbättrade navigerbarheten hos webbapplikationens köpsida. Avslutningsvis visade resultaten även att en intuitiv design som liknande andra hemsidor var viktigt för att minimera förvirringen vid genomförandet av en uppgift. Detta resulterade i slutsatsen att webbapplikationens övergripande layout, design och filtreringsfunktioner alla är viktiga aspekter som påverkar den upplevda nav- igerbarheten och därmed användarvänligheten hos webbapplikationen.

Preventing damages from flooding is critically important for city managers and planners.Efforts in protecting infrastructure from flooding are often coupled with building hydrologicmodels to provide predictions of what is likely to happen during storm events. As land usechanges, these models must be updated, which is more challenging with sophisticated models. Ateam of researchers from universities in Utah and Wyoming have been developing tools forwater management in the Intermountain West as part of a collaborative NSF research grantcalled CI-WATER. In particular, a free and open source web platform called Tethys has beendeveloped to support the development and hosting of hydrologic web applications. Tethys wasused to develop a prototype application that uses a GSSHA runoff model and allows users tochange land-use inputs to simulate the impact on a watershed for any type of land use change.The application also provides a method to run the edited model and produces a comparisonreport of before-and-after runoff and water depth as part of a decision-support framework.

Human beings have always had goals which they have tried to reach. With the pace of the technological development, requests for digitalized solutions to problems which previously have been faced without technology increase. This study tests whether a web application could help users to achieve their goals. This was conducted by implementing three functions: Monetary incentive, publication and reminders. The functions’ design and implementations of these are supported by scientific theory. The purpose is to increase the number of users who fulfil their goals, thus helping people to achieve goals, with the help of the three implemented functions. In this study, a user test is conducted with the web application’s functions where the results are based on a test group. The user test results in both quantitative and qualitative data. The results of the study shows that a web application is a possible tool to increase the users’ chances of reaching their goals. This report also presents suggestions for improvement of the functions, which was clarified in the user tests. / Människor har i alla tider haft mål som de försökt uppnå. I takt med den tekniska utvecklingen ökar efterfrågan på digitaliserade lösningar på problem som tidigare hanterats utan tekniskt stöd. I denna studie testas huruvida en webbapplikation kan hjälpa användare att nå sina mål. Det utfördes genom att implementera de tre funktionerna monetära incitament, offentliggörande och påminnelser. Funktionernas design och implementeringen av dessa stöds via vetenskaplig teori. Syftet är att med hjälp av dessa funktioner öka antalet användare som uppfyller sina mål, sålunda hjälpa människor klara sina mål, med hjälp av de tre funktionerna. I arbetet utförs ett användartest med webbapplikationens funktioner där resultaten baseras på en testgrupp. Användartestet resulterar i både kvantitativa och kvalitativa data. Resultaten av arbetet visar på att en webbapplikation med de tre funktionerna är ett möjligt verktyg till att öka användarens chanser att nå sina mål. I arbetet påvisas även förslag kring hur utformningen av dessa funktioner vidare skulle kunna förbättras, något som klargjordes främst av data från användartestet.

This master thesis is conducted as a conclusion of Master of Science degree in Production Engineering and Management at KTH Royal Institute of Technology. The focus of this thesis work is to make the work more convenient and improve production efficiency by building a management information system (MIS) thus replacing manual and decentralized information management mode on the shop floor. With the use of the computers in the office and tablets beside the machine of each work center on the shop floor, personnel can have access to the necessary information easily and quickly.   This management information system is built according to the actual production situation and needs in Bosch Rexroth AB in Mellansel. First, research on the production process and the management mode in the factory is conducted. Then, the form and the architecture of the system are decided. After thorough understanding and comparison, web application form and currently widely used Browser/Server (B/S) architecture are adopted. Finally, during the detailed design and system implementation process, databases and functional modules are developed. Microsoft Access is chosen as the database implementation. Microsoft Visual Studio.NET combined with C# language and IIS (Internet Information Service) is chosen as the application development tool. When conducting the user trial test on the shop floor, functions of this application system well meet the requirements, and associates can easily and quickly access the information. This application system can speed up the information flow in production, realizing more scientific, standardized and efficient management, which ultimately promotes the production and management of the enterprise.   This management information system realizes the following functions in a digitized way: 1. system security management: user registration, log in and permission settings; 2. drawings viewing; 3. instructions viewing; 4. maintenance recording and checking; 5. deviation reporting and processing; 6. process confirmation recording and checking. / Denna masteruppsats är slutuppgiften för civilingenjörsexamen i produktionsteknik och management på Kungliga Tekniska högskolan. Uppsatsens fokus är att skapa ett mer anpassat arbete samt öka produktionseffektiviteten genom att skapa ett informationshanteringssystem (MIS) och därmed ersätta manuell och decentraliserad informationsstyrning på verkstadsgolvet. Genom att använda datorer på kontoren samt surfplattor vid maskinerna på varje arbetsstation kan personalen snabbt och enkelt få tillgång till nödvändig information.   Detta informationshanteringssystem är utformat efter den nuvarande produktionssituationen och behoven hos Bosch Rexroth AB i Mellansel. Inledningsvis har en undersökning av produktionsprocessen och fabrikens ledningssätt utförts. Därefter har beslut tagits om systemets utformning och arkitektur. Efter djupare analys och jämförelse, har valet fallit på en webbläsar-/serverarkitektur (B/S) . Slutligen, under den detaljerade systemutformningen och -implementeringen utvecklades databaser och funktionella moduler. Microsoft Access har valts för databasimplementering. Microsoft Visual Studio.net i kombination med programspråket C# och IIS (Internet Information Server) har valts som utvecklingsverktyg. Vid införande och test i verkstaden visade sig systemets funktioner väl svar mot behoven och personalen kunde enkelt och snabbt komma åt informationen. Detta system kan öka informationsflödet produktionen och främja metodisk, standardiserad och effektiv förvaltning, vilket gynnar företagets produktion och styrning.
