IP-adresserna under IPv4 är inte tillräckliga och har på många delar i världen redan tagit slut. IPv6 erbjuder många fler tillgängliga adresser och övergången till protokollet har redan börjat. Det Gävlebaserade företaget Interlan erbjuder en tjänst som kontrollerar om kommuner och myndigheter i de nordiska länderna är nåbara via IPv6 samt om de är säkrade med DNSSEC. Denna rapport beskriver jobbet med att förbättra och göra deras tjänst anpassningsbar för flera länder. Processen som beskrivs är parametriseringen av skripten som samlar data, skapandet av en databas att lagra data i, och ändringar till hur data presenteras så att det går att lägga till flera länder.

The presented thesis deals with the subject of tracking via GPS and focuses on possibilities of the practical implementation of user tracking system with the help of mobile end user devices. The introductory theoretical part shortly describes the properties and history of the GPS navigation system. It outlines possible development of end user mobile applications on the level of operating systems and mobile web applications. The final theoretical part provides a short outline of properties of tacking systems available in the Czech market. The primary aim of the thesis was to create an application which would enable the tracking of user position via GPS. The practical part describes the selected solution as well as the individual parts of the designed tracking system. The resulting system allows to record and track user position determined by a mobile phone with an integrated GPS module. The systems also enables the creation of user groups, tracking their routes and visualization of the given position or entire route on a map.

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)

Η παρούσα διπλωματική εργασία αναφέρεται στην δημιουργία μιας εφαρμογής για κινητά τηλέφωνα, σε πλατφόρμα J2ME. Η εφαρμογή αυτή δίνει τη δυνατότητα στους χρήστες της, με τη βοήθεια υπηρεσιών βασισμένων στη θέση, να συγκρίνουν τις τιμές στις οποίες πωλούνται διάφορα βιβλία στα καταστήματα της περιοχής τους. Για την ανάπτυξη αυτής της εφαρμογής χρησιμοποιήθηκαν υπηρεσίες διαδικτύου που επιτρέπουν την επικοινωνία μεταξύ κινητών συσκευών και ενός κεντρικού εξυπηρετητή. Επίσης, αναπτύχθηκε μια βάση δεδομένων από την πλευρά του εξυπηρετητή, η οποία ενημερώνεται από τους ίδιους τους χρήστες. Για τον καθορισμό της γεωγραφικής θέσης του χρήστη χρησιμοποιείται το σύστημα GPS, ενώ για την παρουσίαση των αποτελεσμάτων χρησιμοποιήθηκε το Static Maps API. / The purpose of this diploma thesis is the development of an application designed for mobile phones, based on a J2ME platform. This application enables the users to use their phones in order to compare the prices of books among stores of a specific area. The development of this application includes a distributed system, which consists of two components: the client application, namely the users and the server application that contains a data base. This data base gets updated by the end users. The communication between the server and the client is based on Web Services. The users’ location is determined by the phone’s embedded GPS receiver. Finally, the Static Maps API is used for mapping the results.

Denna rapport avhandlar ett arbete inom ämnet datavetenskap och handlarom utvecklingen av ett system för att studera restidkvoten för sträckor somtrafikeras av Västtrafik, som är en av Sveriges största regionalakollektivtrafikmyndigheter. Restidskvoten anges som förhållandet mellanrestiden med kollektivtrafik och att resa med personbil ([restidkollektivtrafik] / [restid biltrafik]). Med detta som grund har ett system föratt inhämta data om restider med hjälp av Google Maps Directions API samtberäkna restidskvoter och annan metadata utifrån denna insamlade dataskapats. Systemet används till att göra dagliga körningar och lagrar inhämtaddata i en databas hos Västtrafik. Till systemet finns också en dashboard somkan användas för att göra sökningar i databasen som byggts upp och på såsätt hämta, visualisera och analysera önskad data. Restidsdata förkollektivtrafik som erhållits från Google har i stickprov jämförts medrestidsdata från Västtrafik och även om det fanns några avvikelser så stämdede väl överens. Därav dras slutsatsen att data från Google går att använda tillatt beräkna och analysera restidskvoter.

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 first step of Master's thesis was to gain knowledge about technologies Adobe Flex SDK and Google Maps API. Knowledge was used to develop an application, which let users create, generate and modify graphical wireless network model. Position and characteristics of each single unit are monitored either in a map interface or in building plans. Dates are gathered from forms filled by current user, from external file or periodically from connected database system. Theoretical part enlightens technologies that were used. It describes program development and solutions, which were made, along with examples of the source code. Included are printscreens of graphical user interface as well as description of how does it all work.

This thesis deals with notification between smart phone and application server which controls intelligent home. It is focused on Android mobile platform and it is implemented for that platform. Notification service Google Cloud Messaging is used because it is not possible to directly address mobile phones from server. Based on actual position and user defined area the server is informed about moving to or from the area. The server can perform defined event automatically with these information. Implementation was tested in real system. Alpha and beta versions were regularly published.
