Master of Science / Department of Computing and Information Sciences / Daniel A. Andresen / In COBMIN project, we explore two popular software architectural pattern to implement WHO (World Health Organization) STEPS Instrument for Non-Communication Diseases Risk Factor Surveillance for Nepal. COBMIN web application implements Model-View-Controller(MVC) pattern, which divides the application into three interconnected parts - model, view, and controller. Similarly, COBMIN mobile application utilizes one of the most popular Model-View-ViewModel (MVVM) software architectural pattern which isolates the development of graphical user interface from the business logic and data models. We implement above-mentioned pattern using new .Net Core technologies and a cross-platform mobile development API Xamarin.Forms. The COBMIN project comprises of a web application, a web API, and a mobile application to facilitate community-based management of hypertension in Nepal. The primary purpose of the web application is to manage demographic, behavioral, and physical information of the members of the community who are part of the study group. The mobile application is used to expedite the process of data acquisition from the members. The Web API defines request-response message system for mobile client application employing the central data storage.

Preparing dedicated environments for testing often requires time consuming, manual configurations to be made on databases and the Windows Registry. A proposed Windows application could improve the efficiency and accuracy of such settings by automating the processes and providing a user-friendly graphical user interface. On behalf of Ninetech, a consulting company, such an application was therefore developed - KlarSynt Tools. This application was to enhance the company's previous methods of configuring test environments by removing the need of manual tasks and the use of an unoptimized tool called Verktyg. In the development of the application features such as connecting to servers, retrieving data from databases, and automatic configurations of the Windows Registry was implemented. Problems such as automating manual tasks had to be dealt with for providing accuracy of the configurations. The usage of development patterns such as MVVM was also utilized in the project to provide flexibility in the program code, and in that way prepare the software for future development. Finally, user-friendliness was integrated into the application interface to provide efficiency in the usage of the application. This project resulted in that a Windows application was developed to accurately and efficiently configure settings to a database and the Windows Registry. The developed application showed to significantly reduce the number of steps required and the time taken to perform the configurations in the old process.

Software development is of great significance in manufacturing and process industry. Software can, for example, make production more efficient and monitoring easier. In paperboard industry testing the product, that is, paperboard, is important. Testing is done to make sure that the product meets the requirements of the customers who transform the paperboard to packaging products. In the Skoghall paperboard Mill operators make use of a range of different test methods. Since the work pace is high and the product is being continuously tested improvements of the workflow at the laboratory are always of interest.   The aim of this project is to develop a program that connects test instruments at Skoghall Mill’s test laboratory to the Mill’s network. The motivation is to automate part of the work process by removing the step of manually reading measurement values from the test instruments. The scope of this project includes developing software that connects one of the instruments (the Short Span Compression tester [1] or SCT) at the laboratory to the Mill’s network. This program, named TestLink, will work as a proof of concept for connecting instruments using a common interface. The software is constructed using a modular approach forming a platform where an additional instrument can be connected by creating a new module. The software is developed in Visual Studio using C# as the programming language. The software architecture follows the MVVM [2] (Model View ViewModel) design pattern paradigm and WPF [3] (Windows Presentation Foundation) is used to construct the graphical user interface. The result shows that time savings can be made when automating part of the work with the introduction of new software.

The main concern of this thesis is the design and implementation of advanced Web application in ASP.NET 1.0 Core, consisting of a presentation web and administration section. A part of the thesis is also design of a custom architecture for a data source (CRUDQ) suitable for any application, whose implementation is further demonstrated in the developed web application. Selected database system is document database called MongoDB, which is accessed using the author designed architecture approach. Other important aspects of the work includes for example effective interconnection between MVC and MVVM architectures, which is achieved by custom generator of JavaScript data model. The generated data model is used by KnockoutJS framework to ensure the functionality of user interface. The web application is fully functional simple CMS, executable on three most widely used desktop operating systems, using the latest technology tools and design patterns.

Wearable Microneedle (MN)-based sensors have been developed in a joint collaboration between KTH and KI in order to potentially replace invasive clinical tests such as arterial blood gas measurement. For research purposes, an IoT software platform is needed for convenient real- time observation/calibration of raw data, and observation of calibrated concentrations. In order to implement the functionality as requested by the project owners, a front-end iOS application and a back-end Node.js application were implemented. The Front-end application is written utilizing the Model-View- Viewmodel (MVVM) design pattern, allowing functionality such as creating user accounts, user login/logout, setting up a device and its micro-needles with associated analytes, observing the raw real-time analyte data in a graphical interface, calibrating the MNs aswell as observing the calibrated measurement in a graphical interface. The server-side Node.js application is designed following a Representational State Transfer (REST) architecture by utilizing the ExpressJS, MongoDB, and Mongoose object modelling libraries. The back-end application provided several Application Programming Interface (API) endpoints in order to allow fundamental Create-Read-Update-Delete (CRUD) operations for user, device, micro-needle and measurement database models. The final software products and their functionalities were tested using iOS simulators and API interaction tools by imitating real time measurements. Also, performance benchmarks were performed for two scenarios, project optimums and project extremes, both in the back-end and in the frontend software. This was in order to determine if the platform meets the project prerequisites that were set by project owners. As a result, system performance and functionality were found satisfactory for utilization in the research environment for the development of the MN-based patches. / Kroppsburna mikronåls-baserade sensorer har utvecklats i ett gemensamt samarbete mellan KTH och KI för att potentiellt kunna ersätta invasiva kliniska provtagningar som arteriell blodgasmätning. För forskningsändamål behövs en IoT-programvaruplattform för praktisk realtidsobservation samt kalibrering av sensorernas utdata. För att implementera funktionaliteten som begärdes av projektägarna, skapades en frontend-applikation för iOS-enheter vars backend bygger på en Node.js-applikation. Frontend-applikationen är skriven med hjälp av designmönstret gls MVVM, vilket möjliggör funktionalitet som skapande av användarkonton, användarinloggning samt utloggning, konfigurering av enheter och dess mikronålar med tillhörande analyserade värden, observation av realtidsdata i ett grafiskt gränssnitt, kalibrering av glspl MN samt observation av den kalibrerade mätningen i ett grafiskt gränssnitt. Node.js- applikationen på serversidan är utformad enligt gls REST -arkitekturen genom att använda objektbiblioteken ExpressJS, MongoDB samt Mongoose. Backend-applikationen tillhandahöll flera gls API-slutpunkter för att möjliggöra grundläggande gls CRUD-operationer för databaser av användare, enheter eller mikronålar. Den slutliga produkten och dess funktioner testades med hjälp av iOS- simulatorer och API-interaktionsverktyg genom att imitera realtidsmätningar från en mikronålsenhet. Dessutom utfördes prestandatest för två scenarier, optimala samt extrema förhållanden, både i backend samt frontend- programvaran. Detta för att avgöra ifall plattformen uppfyller de krav som hade ställts av projektägarna. Systemprestanda samt funktionalitet har av testerna bedömts vara tillfredsställande för användning i forskningsmiljön för vidare utveckling av gls MN -baserade sensorer.

Every software program that interacts with a user requires a user interface. Model-View-Controller (MVC) is a common design pattern to integrate a user interface with the application domain logic. MVC separates the representation of the application domain (Model) from the display of the application's state (View) and user interaction control (Controller). However, studying the literature reveals that a variety of other related patterns exists, which we denote with Model-View-* (MV*) design patterns. This thesis discusses existing MV* patterns classified in three main families: Model-View-Controller (MVC), Model-View-View Model (MVVM), and Model-View-Presenter (MVP). We take a practitioners' point of view and emphasize the essentials of each family as well as the differences. The study shows that the selection of patterns should take into account the use cases and quality requirements at hand, and chosen technology. We illustrate the selection of a pattern with an example of our practice. The study results aim to bring more clarity in the variety of MV* design patterns and help practitioners to make better grounded decisions when selecting patterns.
