Digimergo är en digitalisering av Emergo Train System, ett system där personal inom räddningstjänst kan öva på olika katastrofscenarion. För att göra Digimergo användbart behövdes ytterligare programvara: ett administrationsverktyg till övningar och en scenarioeditor. I det programvaruutvecklingsprojekt som denna rapport behandlar har ny programvara utvecklats och integrerats med det ursprungliga Digimergosystemet. I den här rapporten diskuteras vilka risker som existerar när ny funktionalitet skall läggas till ett gammalt projekt samt hur dessa risker kan minimeras. Rapporten undersöker också vilka utvecklingsmetoder som lämpar sig i projekt där ny funktionalitet ska läggas till befintliga system. Resultatet visar att den största risken med att utöka befintliga projekt är att underskatta tiden som krävs för att sätta sig in i projektet i fråga. Det mest effektiva sättet att minimera risken för detta är att mycket tidigt studera det tidigare arbetet och utbilda projektmedlemmarna i det gamla systemet. Ett annat angreppssätt är att välja en metod som är flexibel när det kommer till nya risker eller ändringar i projektets plan, förslagsvis iterativa metoder.

Model-Driven Engineering has been developing since the first release of the Unified Modeling Language, passing several milestones and advancing ever since. Model-Driven Engineering is being used in various fields like medical, cyber-physical systems, web applications, etc. It is an engineering paradigm that allows developers to model systems at the level of abstraction of their choice. There are many available tools in the market offering different modelling capabilities to their users. Making use of more than one tool would give the users a wider range of options and higher flexibility in modelling their applications. The current market of open-source modelling tools has two main actors, being JetBrains MPS, mostly focused on textual modelling languages, and Eclipse Modelling Framework, mostly focused on graphical modelling languages. The goal of this thesis is to design and implement a bridge between these two modelling environments. More specifically, we engineer the modelling language Ecore, at the heart of the Eclipse Modeling Framework, in JetBrains MPS in order to enable the exchange of metamodels based on Ecore from MPS to Eclipse Modeling Framework.

Background: Due to the complexity involved in robotic software development, the progress in the field has been slow. Component-based software engineering was observed to have a strong influence on the improvement of the robotic software development process and its adoption achieved good results. DevOps was seen to be compatible and produced efficient results in software engineering. Objectives: The aim of this thesis work is to present the potential usage of DevOps practices in robotic software development. 15 DevOps practices were selected from prior research from software engineering and mapped to the robotic software development process and checked for success in terms of applicability and effectiveness. Methods: By performing a research synthesis of the literature, the usage of DevOps practices in robotic software development is proposed and presented. Interview based survey was performed by approaching industry experts on robotic software development to get their response on the results of the research synthesis. Results: The applicability of the DevOps practices in robotic software development is presented and the implications of the potential usage of the practices in the proposed manner are discussed. The potential advantages and limitations of the proposed mapping are discussed and presented. Conclusions: DevOps, like other software development frameworks, has various observable advantages when applied in robotic software development. The interviews confirmed the need for DevOps to be adapted into robotic software development and the benefits it has.

Background. Websites of 2020 are often feature rich and highly interactive applications. JavaScript is a popular programming language for the web, with many frameworks available. A common denominator for highly interactive web applications is the need for efficient methods of manipulating the Document Object Model to enable a solid user experience. Objectives. This study compares Vanilla JavaScript and the JavaScript frameworks Angular, React and Vue.js in regards to DOM performance, DOM manipulation methodology and application size. Methods. A literature study was conducted to compare the DOM manipulation methodologies of Vanilla JavaScript and the selected frameworks. An experiment was conducted where test applications was created using Vanilla JavaScript and the selected frameworks. These applications were used as base for comparing application size and for comparison tests of DOM performance related metrics using Google Chrome and Firefox. Results. In regards to DOM manipulation methodology, there is a distinct difference between Vanilla JavaScript and the selected frameworks. In Vanilla JavaScript DOM manipulation is handled by direct interaction with the DOM interface. When using the selected frameworks the actual interaction with the DOM interface is abstracted away from the developer and handled by the framework. While React and Vue.js both have implemented a Virtual DOM to optimize DOM interactions, Angular has implemented Incremental DOM. Vanilla JavaScript had the best DOM performance in all tests and the smallest application size. Amongst the frameworks React had the best DOM performance, Angular performed close to React in nearly all test, and Vue.js was slightly slower in most tests. In nearly all tests the applications performed better in Google Chrome. Conclusions. Vanilla JavaScript and the selected frameworks, and thereby their DOM manipulation methodologies, are all feasible alternatives for creating interactive web applications with high DOM performance. Tests indicate that Vanilla JavaScript and the selected frameworks achieves better DOM performance in Google Chrome compared to Firefox.

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 thesis presents a method to develop a visualization software for time-varying and geographic-based data. The machine learning team at Ericsson has collected data from their machine learning algorithms. The data set contains timestamped and geographic information. To have a better understanding of the result made by the machine learning algorithms, it is important to understand the pattern of the data. It is hard to see the pattern of the data by only looking at the raw data set, and data visualization software will help the users to have a more intuitive view of the data.  To choose a suitable GUI library, three common GUI libraries were compared. The Qt framework was chosen as the GUI library and development framework because of its wide-range support to user interface design. Animation is the main method to visualize the data set. The performance evaluation of the software shows that it handles the back-end data efficiently, renders fast in the front-end and has low memory and CPU usage. The usability testing indicates that the software is easy to use. In the end, the thesis compares its method to a previous method, developed in R. The comparison shows that even though the old method is easier to develop, it has worse performance.

Context: API growth is accelerating. RESTful APIs are gaining traction and are backed by major players. Extending the APIs commonly introduce antipatterns, which are bad solutions to problems. Objective: The purpose of this review is to identify and analyze the current, state-of-the-art approaches in detecting antipatterns in RESTful APIs. Method: Six research questions are clearly defined. Search strings are used in digital libraries to identify studies in the field of antipatterns in RESTful APIs. The studies must come from reputable sources. Studies are subjected to inclusion-exclusion and quality assessment. Results: Eight studies were selected. Each study has one main approach. Three classes were created to identify the types of approaches. All approaches require expert domain knowledge to apply and vary in the difficulty of application. The accuracy of the approaches is above 80\%. Four types of antipatterns were identified and the approaches detect one or multiple types of antipatterns. Conclusion: Various techniques were discovered, each selected study presented a single technique. Classifications for the techniques and antipatterns were made. The research field is young with future work planned.
