The purpose of this project is to create a website with a React-based prototype recommendation system of a large cultural collection. The aim of the website is to provide a function that allows a user to upload an image to which the system consequently recommends correlating artwork from the publicly available collection of the Metropolitan Museum of Modern Art (MET). The correlation coefficient between the uploaded image and the artworks from (MET) is acquired through Pearson Correlation. Furthermore the artwork with the highest correlation to the uploaded picture is shown first, then each subsequent artwork is shown in order of highest correlation. The main challenge for building this prototype was to combine the different components together with JavaScript and the REACT framework. The recommendation engine demands numerical representations of these artworks, and most effort was given to the automatic conversion of photos of artworks into a proper format for the recommendation engine.

Der Schwerpunkt dieser Arbeit liegt auf der Konzeption sowie prototypischen Implementierung eines web-basierten Dashboards zur Softwarevisualisierung. Ziel der Arbeit ist es, ein Dashboard zu entwickeln, welches Informationen eines Softwareprojekts dynamisch aus einer Graphdatenbank visualisiert und Projekteitern aufgabenbezogen zur Entscheidungsunterstützung darstellt. Derzeit existiert keine Softwarelösung, die diesen Anforderungen vollumfänglich gerecht wird. Es existieren jedoch bereits Bibliotheken und Softwaresysteme, welche Teilaspekte zu einer möglichen Gesamtlösung beitragen können. Diese können bei der prototypischen Implementierung von Nutzen sein und müssen daher beachtet werden. Um die Ziele der Arbeit zu erreichen, werden verschiedene Forschungsmethoden angewandt. Es wird eine Literaturrecherche durchgeführt, mit dem Ziel, typische Aufgaben von Projektleitern im Bereich Software Engineering zu identifizieren. Um die vom Dashboard zu unterstützenden Aufgaben ableiten zu können, werden außerdem verschiedene existierende Dashboard-Werkzeuge analysiert. Mithilfe der gewonnenen Ergebnisse wird das Dashboard konzipiert und prototypisch implementiert. Durch eine Fallstudie anhand von Open-Source-Projekten wird das Dashboard abschließend evaluiert.:1 Einleitung 1.1 Motivation und Problemstellung 1.2 Zielstellung 1.3 Methodisches Vorgehen 2 Grundlagen 2.1 Softwarevisualisierung 2.2 jQAssistant 2.3 Neo4j 2.4 Webanwendungen und web-basierte Frameworks 2.5 D3.js 2.6 Dashboards 3 Konzeption 3.1 Mission Statement 3.2 Architekturziele 3.3 Kontextabgrenzung 3.3.1 Fachlicher Kontext 3.3.1.1 Literaturrecherche zu typischen Aufgaben von Projektleitern 3.3.1.2 Analyse existierender Dashboard-Werkzeuge 3.3.1.3 Use-Case-Diagramm der zu unterstützenden Aufgaben 3.3.1.4 Mockups der Benutzungsschnittstelle 3.3.2 Technischer Kontext 3.4 Randbedingungen 3.4.1 Technische Randbedingungen 3.4.2 Organisatorische Randbedingungen 3.5 Risiken und technische Schulden 3.6 Entwurfsentscheidungen 3.6.1 Auswahl des Neo4j-Treibers 3.6.2 Vergleich existierender Webframeworks 3.6.2.1 Angular 3.6.2.2 Backbone.js 3.6.2.3 Ember.js 3.6.2.4 Vue.js 3.6.2.5 React 3.7 Lösungsstrategie 4 Implementierung 4.1 Implementierungskomponenten 4.1.1 CoreUI 4.1.2 Nivo 4.2 Dashboard 4.2.1 Startseite 4.2.2 Einstellungen 4.2.3 Benutzerdefinierte Abfragen 4.2.4 Visualisierungskomponenten 4.2.4.1 Struktur 4.2.4.2 Dateitypen 4.2.4.3 Abhängigkeiten 4.2.4.4 Aktivitäten 4.2.4.5 Wissensverteilung 4.2.4.6 Hotspots 4.2.4.7 Statische Quellcodeanalyse 4.2.4.8 Testabdeckung 4.2.4.9 Erstellung 4.3 Eingesetzte Werkzeuge 4.3.1 Entwicklung und Test 4.3.1.1 Jest 4.3.1.2 Codecov 4.3.1.3 Travis CI 4.3.1.4 Prettier 4.3.1.5 Docker 4.3.2 Installation und Wartung 5 Evaluation 6 Fazit und Ausblick

Saab is a large swedish company providing a multitude of different products and services. This also means that Saab has to provide support and customer service for said products. Currently this is handled online in Support Portals, where customers and partners can access product information as well as an issue management system called SIRS. In the current situation the system is tailored for a desktop experience, and the workflow is therefore limited in terms of mobility. This project aims to allow the users to be more mobile by investigating the possibility of developing a mobile application for usage with SIRS. During the project a proof of concept of such an application has been developed. The implementation relies largely on using currently available api:s and when necessary porting some code from server to client side. By using various UX-related methods during the development of the application it is expected that the application is user friendly and fits the target audience. When looking at the result of the work, it is indeed possible to integrate a standalone mobile application with SIRS. The application also has usability which is comparable to the current system. However, some limitations were found that required rewriting the existing system to provide necessary data to client side applications like the one developed in this project. To conclude, the application is a proof of concept that shows what can be done without modifying the current system. Some of the major things that has to be modified before taking the application to production, such as stability concerns and testing, is also presented as results of the project.

Arbetet jämför JavaScript-ramverken Vue.js och React huruvida vilket av ramverken som presterar lägst svarstider i ett experiment. Bakgrunden till arbetet är att undersöka visualiseringav data och i form av en interaktion som är filtrering. Arbetet är inriktat på parkeringsplatser som blir svårare att finna och att filtrering används för att finna lediga parkeringsplatser. Experimentet består av en webbapplikation skapad i en implementation av respektive ramverk som innehåller en lista med parkeringsplatser som går att filtrera. Mätningar genomfördes automatiserat genom ett egenskrivet skript med användning av Tampermonkey för att få fram ett resultat. Resultatet visar att det fanns en signifikant skillnad mellan ramverkens resultat från experimentet till fördel för Vue.js. Det går att följa arbetet steg för steg hur det genomfördes med mål att studien ska vara replikerbar.
