The Expanded Program on Immunization Sampling Method (known simply as EPI sampling) is a two-stage sampling procedure originally intended for quick estimation of disease prevalence in large geographical regions. The method was developed in the 1970s and all the subsequent assessments of its performance have been conducted by simulation. In her master's thesis, Reyes (2016) studied in detail the second-stage sampling of the method by developing formulas for the exact calculation of the household inclusion probabilities when sectors are used to identify the initial household to generate the EPI samples. The inclusion probabilities were used in turn to obtain exact mean, bias, variance and mean square error of any estimator of disease prevalence in the population. Thus, no extensive simulations are required and the results are exact rather than just estimates. This thesis is an extension of Reyes' (2016) work. The extension is two-fold; (a) employing strips rather than sectors because they narrow the geographic area for field workers and to use strips to select the first household for the EPI sample at the secondary stage, and (b) carrying out an analysis on simulated population and sampling plans, using both stages of the EPI method. Analyzing the simulated populations showed that equal weight estimator that samples primary units with replacement with probability proportional to size (EW1) should be used when the target characteristic is thought to be spread randomly throughout the population, and the Horvitz-Thompson estimator that samples primary units systematically with replacement (HTSYS) should be used when the disease is believed to spread from a central location or through pocketing. Comparing the strip and sector sampling methods at the secondary stage using their effective areas leads to a comparative basis in which the inclusion probabilities are identical for both methods. / Thesis / Master of Science (MSc)

The use of geographical data is increasing in real world applications and due to this, Geographic information systems (GIS) are a growing interest area for research nowadays. Today, GIS is combined with the World Wide Web (WWW) to provide information to a lot of people. Web-based GIS applications have gained popularity because of their easy use and simplicity. Through browsers, web-based GIS applications can display maps with features like buildings, forests, roads and even traffic. Furthermore spatial data can be analyzed and large amounts of data can be viewed on small screens by zooming and panning the map. So having all the above features, effective web-based GIS applications should be designed in a way that they should be easy to use and understand for users. Usability evaluation is becoming an important part of Interaction Design to find out the user´s needs and requirements. In this study two web-based GIS applications (Google Maps and MapQuest) are evaluated to find out usability problems. To accomplish the main goal of this study, different techniques are used. Special criteria are adopted for usability evaluation of these two web-based GIS applications. Usability tests have been performed with six graduate users and questionnaires were filled out by these users. Interviews were conducted with six users to validate the results. The authors have provided a number of suggestions based on the problems that were identified in this study for Google Maps and MapQuest to improve the usability of these applications.

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.

The human’s ability to see, listen and speak is naturally embedded in how we interact and communicate with each other, but not only do we interact with other humans, we also spend a lot of time interacting with computers. In our study we take a starting point in embodied interaction and draw on people’s abilities from everyday life and apply them to computation in form of eye-tracking and speech recognition. Previous research mainly explored these inputs separately and little has been discovered regarding the combination. We applied a qualitative approach consisting of free surfs, task based evaluations and ten interviews, and we aimed for an understanding of how people perceive this interaction and to discover potential use contexts. The results indicate that people are positive towards the combination of eye-tracking and speech recognition for interacting with computers but found it hard to imagine a rich set of contexts in which it could be used.

A nuclear waste stream is the complete flow of waste material from origin to treatment facility to final disposal. The objective of this study was to design and develop a Geographic Information Systems (GIS) module using Google Application Programming Interface (API) for better visualization of nuclear waste streams that will identify and display various nuclear waste stream parameters. A proper display of parameters would enable managers at Department of Energy waste sites to visualize information for proper planning of waste transport. The study also developed an algorithm using quadratic Bézier curve to make the map more understandable and usable. Microsoft Visual Studio 2012 and Microsoft SQL Server 2012 were used for the implementation of the project. The study has shown that the combination of several technologies can successfully provide dynamic mapping functionality. Future work should explore various Google Maps API functionalities to further enhance the visualization of nuclear waste streams.

The main goal of this work is to implement a system, which will be able to optimize routes between warehouses and selected customers and visualize them using maps by the Google Inc.
