However, these figures hide important information about the interaction between the traveler and the visited location. There is a wide range of destinations growing up by demand of visitors, oblivious to issues of relevance to the tourism planning, such as the availability of accurate, which enable the tourist an holistic view of geographic space. After the advent of the new technologies, the decision of the travel to a specific touristic destination increasingly depends of the quality in access to information. So, this research aims to promote a discussion about the impact of touristic information organized through Geographic Information System - GIS on web environment for communication with tourist. In this context are analyzed the ways of the Tourism by threefold bias of Virtual Communication, Touristic Cartography and Geotechnologies as strategies for the better reveal the space to the new tourist profile of the digital age. The results of these reflections are gathered on the project SIGTUR Alto Paraíso, a proposal of the GIS application online using the Google Earth software as a dynamic and interactive information platform for viewing maps and elements of touristic space. The spatial area adopted is the Alto Paraiso city, in whose territory is the gateway to the National Park of Chapada dos Veadeiros- NPCV and sceneries of natural beauty that position this area as one of the main ecotourism destinations the State of Goiás. / O turismo tornou-se uma rentável atividade econômica, fato explicado pelo altos índices de emprego e renda decorrentes da circulação de turistas em todo o mundo. Entretanto, esses números escondem dados importantes quanto à interação entre o viajante e o local visitado. Existe grande variedade de destinos crescendo pela demanda de visitantes, alheios a aspectos de relevância para o planejamento turístico, como por exemplo, a disponibilização de informações precisas, que possibilitem ao turista uma visão holística do espaço geográfico. Após o advento das novas tecnologias, decidir a viagem para um destino turístico específico depende cada vez mais da qualidade no acesso à informação. Assim, essa pesquisa busca promover uma discussão sobre o impacto da informação turística organizada através de Sistema de Informação Geográfica – SIG em ambiente web para a comunicação com o turista. Nesse contexto, são analisados os caminhos do Turismo pelo tríplice viés da Comunicação Virtual, da Cartografia Turística e das Geotecnologias como estratégias para melhor revelar o espaço ao novo perfil de turista da era digital. Os resultados destas reflexões são reunidos no projeto SIGTur Alto Paraíso, uma proposta de aplicação de SIG on line que utiliza o software Google Earth como dinâmica e interativa plataforma de informações para visualização de mapas e elementos do espaço turístico. O recorte espacial adotado é o município de Alto Paraíso, em cujo território está a porta de entrada para o Parque Nacional da Chapada dos Veadeiros – PNCV e cenários de beleza natural que posicionam esta área como um dos principais destinos de ecoturismo no estado de Goiás.

Context: The Internet has become a vital channel for disseminating and accessing scientific literature for both the academic and industrial research needs. Nowadays, everyone has wide access to scientific literature repositories, which comprise of both “white” and “Grey” literature. The “Grey” literature, as opposed to “white” literature, is non-peer reviewed scientific information that is not available using commercial information sources such as IEEE or ACM. A large number of software engineering researchers are undertaking systematic literature reviews (SLRs) to investigate empirical evidence in software engineering. The key reason to include grey literature during information synthesis is to minimize the risk of any bias in the publication. Using the state of the art non-commercial databases that index information, the researchers can make the rigorous process of searching empirical studies in SLRs easier. This study explains the evidence of Grey literature while performing synthesis in Systematic Literature Reviews. Objectives: The goals of this thesis work are, 1. To identify the extent of usage of Grey Literature in synthesis during systematic literature reviews. 2. To investigate if non-commercial information sources primarily Google Scholar are sufficient for retrieving primary studies for SLRs. Methods: The work consists of a systematic literature review of SLRs and is a tertiary study and meta-analysis. The systematic literature review was conducted on 138 SLRs’ published through 2003 until 2012 (June). The article sources used are IEEEXplore, ACM Digital Library, Springer-Link and Science Direct. Results: For each of the selected article sources such as ACM, IEEEXplore, Springer-link and Science Direct, we have presented results, which describe the extent of the usage of Grey literature. The qualitative results discuss various strategies for systematic evaluation of the Grey literature during systematic literature review. The quantitative results comprise of charts and tables, showing the extent of Grey literature usage. The results from analysis of Google Scholar database describe the total number of primary studies that we are able to find using only Google Scholar database. Conclusion: From the analysis of 138 Systematic Literature Reviews (SLRs’), we conclude that the evidence of Grey literature in SLRs is around 9%. The percentage of Grey literature sources used in information synthesis sections of SLRs is around 93.2%. We were able to retrieve around 96 % of primary studies using Google Scholar database. We conclude that Google Scholar can be a choice for retrieving published studies however; it lacks detailed search options to target wider pool of articles. We also conclude that Grey literature is widely available in this age of information. We have provided guidelines in the form of strategies for systematic evaluation of Grey literature. / Sammanhang: Internet har blivit en viktig kanal för att sprida och få tillgång vetenskaplig litteratur för både akademiska och industriella forskningsbehov. Numera har alla bred tillgång till vetenskaplig litteratur förråd, som omfattar både "vit" och "grå" litteratur. Den "grå" litteratur, som motsats till "vita" litteratur, är icke-vetenskapligt granskad vetenskaplig information som inte är tillgänglig med kommersiella informationskällor såsom IEEE och ACM. Ett stort antal forskare software engineering genomför systematiska litteraturöversikter (systemkameror) för att undersöka empiriska bevis programvaruteknik. Den viktigaste orsaken till att omfatta grå litteratur under Information syntes är att minimera risken för att partiskhet i publikationen. Använda toppmoderna icke-kommersiella databaser som indexerar information kan forskarna göra rigorösa processen att söka empiriska studier i systemkameror lättare. Denna studie förklarar bevis på grå litteratur när de utför syntes i systematiska litteraturöversikter. Mål: Målen med detta examensarbete är, 1. För att identifiera omfattningen av användningen av Grey litteratur i syntes under systematisk litteratur recensioner. 2. För att undersöka om icke-kommersiella informationskällor främst Google Scholar är tillräckliga för att hämta primära studier för systemkameror. Metoder: Verket består av en systematisk litteraturgenomgång av systemkameror och är en tertiär studie och metaanalys. Den systematiska litteraturstudie genomfördes på 138 systemkameror "publiceras via 2003 till 2012 (juni). Artikeln används källorna är IEEEXplore, ACM Digital Library, Springer-Link och Science Direct. Resultat: För vart och ett av de utvalda artikeln källor såsom ACM, IEEEXplore, Springer-länk och Science Direct, har vi presenterat resultat, som beskriver omfattningen av användningen av grå litteratur. De kvalitativa resultaten diskuterar olika strategier för systematisk utvärdering av grå litteratur under systematisk litteraturöversikt. De kvantitativa resultaten består av diagram och tabeller, som visar omfattningen av Grey litteratur användning. Resultaten från analys av Google Scholar-databasen beskriver det totala antalet primära studier som vi kan hitta med enbart Google Scholar databas. Slutsats: Av analysen av 138 systematiska litteraturöversikter (systemkameror) kan vi dra slutsatsen att bevisen för grå litteratur i systemkameror är cirka 9%. Den procentuella andelen Grey litteraturkällor som används i avsnitt informations syntes av systemkameror är cirka 93,2%. Vi kunde hämta omkring 96% av primära studier med Google Scholar databas. Vi drar slutsatsen att Google Scholar kan vara ett val för hämta publicerade studier dock, det saknar detaljerade sökalternativ för att rikta större pool av artiklar. Vi avslutar också att grå litteratur är allmänt tillgänglig i denna tid av information. Vi har försett riktlinjer i form av strategier för systematisk utvärdering av Grey litteratur. / Affan Yasin : Skype id (affan.yasin) Ijlal Hasnain: Skype id (bluesols)

Context: Due to rapid increase in the population of elderly people, sharing healthcare information has become an essential requirement for the development of e-health system. By conducting a research in e-health and cloud computing we have explored the advantages and disadvantages of sharing healthcare information for elderly people through cloud computing. Objectives: The main purpose of this research is to investigate the suitability of cloud computing to share healthcare information. The study is conducted by exploring the advantages and disadvantages of cloud computing for e-Health systems. Investigating a suitable cloud computing platform is also one of the objectives of this research. Methods: In order to identify and get deeper understanding of these issues, we have performed literature review of E-health, EHI and Cloud Computing technologies and we have develop a prototype application as experiment. Results: Based on the finding of literature review, we came to know that E-health was huge field. It needs a huge infrastructure to establish. The healthcare information in e-health requires quick and easy sharing. In EHI research, we defined EHI and find reasons for sharing elderly healthcare information. At cloud computing research, we knew the concept of cloud computing and found out advantages and disadvantages of implementing e-health in cloud computing. From literature review, we developed sharing application which was used to share EHI in cloud computing. In experiment, we proved our supposition and discussed advantages and disadvantages of sharing EHI in cloud computing by using Google App Engine (GAE). Conclusions: We conclude that cloud computing meets the requirements of sharing EHI, but it also has some limitations due to its architecture and network condition. In this research we have identified further research area that can help in enhancing security and privacy in cloud environment.

In today's society, almost all companies, associations and even individuals have websites, blogs or social media to appear in on the internet, and the competition to succeed appearing on search engines' first pages, which most users only look at, is big. The purpose of this study is to develop proposals for improvement to increase the website traffic for a bed-selling company website, using web analytics and search engine optimization, and to create a deeper understanding of user behavior. This study is based on theories in the field of interaction design with a focus on design principles and cognition. The study uses the methods literature review, web analytics, contextual inquiry sessions and search engine optimization-evaluation in order to generate results. The results gave information about how the user is drawn to the website, and how search engine optimization currently is used for the website. Developing proposals for improvement have been generated based on the results to boost website traffic to the company website. Conclusions in which the study resulted in is, for example, that the study only examines how users find the site starting from a search engine and not why the user uses a search engine, which in a broader study could have been studied for a more in-depth result. Proposals for future research are for example to see how the increase in website traffic is affecting sales both regarding the web shop and in stores.

We live in the fourth generation (4G) of wireless and mobile communications, and for the next generation (5G) we can expect greater flexibility and increased network speed. This will likely contribute to an increased demand for functioning mobile web applications, and it is therefore beneficial for companies to comply with society's technological development. This study aims to investigate how users experience Södra’s website in a mobile interface with focus on the system’s usability, and to identify potential problems on the website regarding Search Engine Optimization (SEO). The research is based on both quantitative and qualitative methods, and the methods that are used in this study are usability testing and web analysis. The findings highlight usability and Search Engine Optimization issues on the website. The fundamental problems the participants had was difficulty using the internal search engine on the website, and locating information caused by intense scrolling. The data gathered through the web analysis shows that keywords are not strategically used in the HTML document, and that the meta descriptions tend to include too many characters. This paper suggests solutions and improvements to these issues found on the website.

Mobile Ad Hoc Networks are flexible, self configuring networks that do not need a fixed infrastructure. When these nets are simulated, mobility models can be used to specify node movements. The work in this thesis focuses on designing an extension of the random trip mobility model on a city section from EPFL (Swiss federal institute of technology). Road data is extracted from the census TIGER database, displayed in Google Earth and used as input for the model. This model produces output that can be used in the open source network simulator ns-2. We created utilities that take output from a database of US counties, the TIGER database, and convert it to KML. KML is an XML based format used by Google Earth to store geographical data, so that it can be viewed in Google Earth. This data will then be used as input to the modified mobility model and finally run through the ns-2 simulator. We present some NAM traces, a network animator that will show node movements over time. We managed to complete most of the goals we set out, apart from being able to modify node positions in Google Earth. This was skipped because the model we modified had an initialization phase that made node positions random regardless of initial position. We were also asked to add the ability to set stationary nodes in Google Earth; this was not added due to time constraints.

Detta examensarbete har utförts i samarbete med företaget Systemagic AB. Systemagic är ett teknikföretag vars expertis ligger inom mjukvaruutveckling inom IPTV-teknologi. Detta innefattar bland annat utveckling av middleware till digitalboxar, också kallade Set-top-boxar. Middleware är den mjuk- och hårdvaruinfrastruktur som sammankopplar de olika delarna av ett IPTV-system. Det är ett distribuerat operativt system som både finns på operatörens servrar samt i slutanvändarens digitalbox. Då det idag ställs allt högre krav på funktionalitet och dynamik från beställare blir utvecklingen av ett modernt middleware mycket resurskrävande. Systemagic anser att en stor bidragande orsak till den resurskrävande utvecklingsprocessen kan kopplas till användningen av scriptspråket JavaScript och är därför intresserade av alternativa metoder. Google Web Toolkit (GWT) är ett Java-ramverk som kan användas för att på ett snabbt och smidigt sätt utveckla interaktiva webbapplikationer. Detta möjliggörs genom att all utveckling sker i Java. Slutprodukten efter kompilering är standard-kompatibel HTML och JavaScript, helt oberoende av Java. Detta examensarbete har gått ut på att undersöka möjligheten att använda Java och GWT för att underlätta och potentiellt snabba upp utvecklingen av ett middleware. Målet var att undersöka om GWT kan användas rakt av för att ta fram den del av ett middleware som återfinns i slutanvändarens box, en så kallad portal, eller om ramverket måste anpassas för att de mest grundläggande funktionerna hos en box ska kunna implementeras. Rapporten beskriver frågeställningar, tillvägagångssätt, problem och  svårigheter som uppstod, de lösningar som använts samt en analys och diskussion av resultatet.

Arbetet handlar om sökmotoroptimering med hjälp av microdata. Hamnar webbsidor som använder sig av det högre upp i det organiska sökresultatet? Eller kan det ge mindre önskvärda konsekvenser? Från början åtogs arbetet att skapa en sökmotoroptimerad sida åt företaget Hårmakarna i Motala och som en naturlig del i arbetet dök användandet av microdataupp. Det tycks vara allmänt vedertaget att tekniker som microdata är gynnsamma vid sökmotoroptimering och frågeställningen kring huruvida ett sådant användande kunde ge en bättre placering i det organiska sökresultatet eller ej tog form. Det var särskilt intressant eftersom det inte verkade finnas några studier som bekräftade frågeställningen. Arbetet blev därför sedan uteslutet inriktat på frågeställningen. Undersökningen genomfördes genom att två webbsidor publicerades. Förutom att den ena sidan innehöll microdata var webbsidorna identiska. Direkt efter publicering genomfördes frekventa undersökningar av Googles sökmotor tills webbsidorna indexerats. Efter det utfördes sökningar på utvalda sökord med målet att få en uppfattning om webbsidornas placering över tid. Resultatet blev oväntat då webbsidan utan microdata visade sig få en sämre placering. Antagligen berodde det på det som Google kallar ”duplicate content”. / This study is dealing with the subject of search engine optimization with the usage of microdata. Do websites that use it obtain a higher placement in the organic searchresult? Or can it bring less desirable consequences? From the beginning the work consisted of creating a search engine optimized website for the Motala-based company Hårmakarna and as a natural part in the work the topicof microdata surfaced. It seems like it is common knowledge that techniques like microdata are beneficial for search engine optimization and the question whether that kind of technique could wield a better placement in the organic searchresult or not took shape. It was particulary interesting since it did not seem to exist any studies that could confirm the question. The study was performed by publishing two websites. Except that one of the websites was using microdata the were identical. When the websites were published examinations of Google's searchengine were performed until both websites were indexed. After that searches were made with selected searchwords and the aim was to get a notion of the websites' placement over time. The result was unexpected as the website with no microdata got an inferior placement probably due to what Google calls ”duplicate content”.

Extraction of streets from Google earth imagery is a hot research topic. The main purpose of this paper is to create a method to extract streets information from satellite image automatically. It is exceedingly difficult to achieve, because every road has different characters and there are a lot of noises (e.g. shadow, building, and vehicle) in the image. By using generic color model and the image analysis techniques, we build up the automatic road extraction system. It extracted road successfully from mid-size city image with a very high extraction rate. Some interesting discoveries and unique creative solution are proposed in this paper.
