Ο σκοπός της διπλωματικής εργασίας είναι η απεικόνιση της βιοϊατρικής πληροφορίας με πρωτότυπο τρόπο, δίνοντας έμφαση τόσο στον σχεδιασμό και στην ανάπτυξη μίας φιλικής διεπαφής για τον χρήστη όσο και στην απόκτηση τεχνικής γνώσης από μέρους μου. Έτσι, μελετήθηκαν υπάρχουσες εφαρμογές-τεχνολογίες και οι αντίστοιχες δυνατότητες που προσέφεραν, σε συνδυασμό πάντα με τις απαιτήσεις και τις ανάγκες των ιατρών. / The subject of the present diploma is the imaging of biomedical information in an original way, emphasizing both the design and development of a user friendly interface and the acquisition of technical knowledge for me. Thus, studied existing applications and technologies and their respective capabilities offered, I tried to make a system always in combination with the demands and the needs of the doctors.

Every day most people are using applications and services that are utilising machine learning, in some way, without even knowing it. Some of these applications and services could, for example, be Google’s search engine, Netflix’s recommendations, or Spotify’s music tips. For machine learning to work it needs data, and often a large amount of it. Roughly 2,5 quintillion bytes of data are created every day in the modern information society. This huge amount of data can be utilised to make applications and systems smarter and automated. Time logging systems today are usually not smart since users of these systems still must enter data manually. This bachelor thesis will explore the possibility of applying machine learning to task logging systems, to make it smarter and automated. The machine learning algorithm that is used to predict the user’s task, is called multiclass logistic regression, which is categorical. When a small amount of training data was used in the machine learning process the predictions of a task had a success rate of about 91%.

Project Meme Evolution Programme (Project MEP) is a research program directed by Raazesh Sainudiin, Uppsala University, Sweden, that collects and analyzes datasets from Twitter. Twitter can be used to understand how ideas spread in social media. This project aims to produce interactive visualizations for datasets collected in Project MEP. Such interactive visualizations will facilitate exploratory data analysis in Project MEP. Several technologies had to be learned to produce the visualizations, most notably JavaScript, D3, and Scala. Three interactive visualizations were produced; one that allows for exploration of a Twitter user timeline and two that allows for exploration and understanding of a Twitter retweet network. The interactive visualizations are accessible as Scala functions and in a website developed in this project and uploaded to GitHub. The interactive visulizations contain some known bugs but they still allow for useful exploratory data analysis of Project MEP datasets and the project goal is therefore considered met. / Project Meme Evolution Programme

Motion controlled games can be a good physical activity for children, but the game has to be fun and engaging. We have, with a starting point in an existing base game, developed an achievement module which follows certain code standards to make it easier to understand, and to make hand overs of the code smoother. More work on the rest of the game has also been done to make it more engaging, while clean up of the existing code to follow the same standards.

This thesis covers the development of web applications with modern programming languages and technologies. The objective of thesis is the research and analysis of modern technologies and subsequent selection of particular programming languages, frameworks and database for development of web application applying those techniques. Based on analysis of modern trends I chose the following technologies: backend development using popular Spring framework based on Java EE, frontend implementation using one of the most widespread scripting languages JavaScript and its known framework AngularJS developed by Google. For data persistence I chose NoSQL database MongoDB. I provided detailed documentation of each implementation step: project definition, requirements analysis, design, implementation and testing.

This master's thesis deals with difficulties of web application development utilizing web services. The theoretical part describes the essence of service oriented architecture and explains the options of integration using web services. The practical part deals with analysis, design and subsequent implementation of web application. Specifically, the implementation of application for task manager, which is divided into two parts. The server side of application exposes REST services and client side that consumes.

Briteback Explore is a service provided by the company Briteback. The service provides a survey tool to its users that allows access to results through the downloading of a comma-separated values (CSV) -file. What was built was a visualization model that provides the survey tool’s users with a graphical representation of the data directly through the service. Providing an overview of the survey results that lessens the amount of information overload perceived by the user while giving the data a structure. A survey based off of the System Usability Scale (SUS) evaluation method was then performed to display to what degree users found the new feature usable. Results showed a satisfactory high score on the SUS adjective rating scale.

I detta dokument gestaltas arbetet med att utveckla ett internt administrationssystem till e-handelsföretaget Ehandelssupport. Detta är ett uppdrag i skarpt läge och grundas i företagets behov av att få bättre och mer användaranpassade webbapplikationer som syftar till att underlätta, förenkla och effektivisera vissa frekvent återkommande arbetsuppgifter. Detta innefattar exempelvis en applikation som kan generera prislappar baserat på produktinformation som lagras i webbshoppen Alfahobbys databas. Det inkluderar också en användarvänlig och effektiv lösning för att kunna skapa och skicka ut digitala nyhetsbrev till företagets kunder. Den färdiga applikationen för prislapparna uppfyller de grundönskemål om funktionalitet som företaget hade på denna samtidigt som den nya lösningen medför en rejäl tidseffektivisering i handhavandet med att skapa prislapparna eftersom datat hämtas direkt från databasen via ett nyimplementerat API. Applikationen använder också ramverket jQuery Mobile vilket stödjer responsiv webbdesign. Arbetet med lösningen för de digitala nyhetsbreven resulterade i ett förslag till företaget som innebär att börja använda verktyget Mailigen, detta skulle både förenkla det redaktionella arbetet och förbättra användbarheten för kunderna exempelvis genom att nyhetsbreven får en responsiv webbdesign. Några områden för eventuell framtida vidareutveckling är exempelvis att för applikationen för prislappar lägga till ytterligare kontroller som förhindrar att användaren skriver in fel värden i vissa funktioner. När det gäller nyhetsbreven skulle fortsatt forskning rörande möjligheten att kunna infoga produktinformation direkt från webbshoppens databas vara aktuellt.

The goal of this thesis is to investigate the W3C Geolocation API from a developer’s perspective, focused on whether it makes development of location-based applications more accessible to developers. This has been investigated by looking at available ways to locate, possible uses, the functionality offered, the necessary level of prior knowledge needed for a developer and requirements on developer tools. This has been achieved through studies in relevant areas, a thorough introduction to W3C Geolocation API functionality, and by using the API to develop two different location-based applications as a demonstration. Testing of applications, on different platforms and in different environments, in conjunction with investigation of the rest of the material has shown that W3C Geolocation API in many ways actually makes development of location-based applications more accessible for developers. The API also provides fully adequate functionality and quality to meet the requirements for development of both simple and very advanced location-based applications. Målet med denna uppsats är att undersöka W3C Geolocation API ur ett utvecklarperspektiv, fokuserat på om den gör utveckling av positionsbaserade applikationer mer tillgänglig för utvecklare. Detta har undersökts genom att titta på vilka positioneringstekniker som är tillgängliga, vilka användningsområden som är möjliga, vilka funktioner som erbjuds och vilka krav som ställs på utvecklaren i form av kunskap och utvecklingsverktyg. Detta har åstadkommits genom studier på relevanta områden, en genomgående introducering av vad W3C Geolocation API har att erbjuda för funktioner, samt användning av API:n i form av två egenutvecklade applikationer. Tester av applikationerna, på olika plattformar och i olika miljöer, har sedan tillsammans med utredning av resten av materialet visat på att W3C Geolocation API på många sätt gör utveckling av positionsbaserade applikationer mer tillgänglig för utvecklare samt erbjuder fullt tillräcklig funktionalitet och kvalitet för att tillgodose de krav som ställs för önskvärda användningsområden.
