Mobile Geographical Information Systems are becoming a more and more important tool for presenting geographical data. They are used to support decision making processes, present an overview of distributed information or are in a form of location based services. The problem lies in the fact that mobile devices have limited resources and should still be able to present massive amounts of content. Ideally, the user and the conditions in which the program runs are well defined, but this is usually not the case. This thesis provides a sample prototype implementation of a mobile GIS developed as an alternative to an existing web-based user interface (UI). It focuses on specific conditions present on mobile devices, ways of presenting the data and possibilities of reusing existing elements from the web UI that could be suitable for the mobile environment.

La télécommunication mobile connecte les personnes de n'importe où à tout moment. La transmission de la voix et des données à travers les réseaux de télécommunication mobile permet d'envoyer des informations et de diriger des transactions d'une manière nouvelle. Cela crée un nouveau domaine d'affaires qui s'appelle du commerce mobile, une affaire étendue basée sur l'Internet avec de nombreux des caractéristiques uniques ajoutés. Comme un soutien fondamental du plate-forme, les réseaux de la télécommunication mobile joue un rôle essentiel dans le commerce mobile. Leurs caractéristiques techniques et le déploiement déterminent l'essence pour le commerce mobile. Dans cette mémoire, nous étudions et présentons les caractéristiques techniques des technologies communications mobiles du réseau 1G à 3G et au-delà. Nous étudions également les technologies WLAN et WAP qui sont courantes dans le commerce mobile en Chine et dans le monde. Le commerce mobile est en train de se développer, le nombre d'utilisateurs de téléphones mobiles sont de plus en plus en Chine et dans ce monde. Les utilisateurs mobiles énormes en Chine ainsi que la maturité des technologies 3G affichent un fort potentiel pour offrir et d'adopter plus les nouveaux services mobiles. Après réviser l'évolution du commerce mobile et l'histoire du succès i-mode au Japon, nous nous concentrons sur le mobile du marché chinois de manière à découvrir son marché, l'infrastructure du réseau mobile, et le modèle d'affaires. Fondé sur la base de notre enquête sur le commerce mobile chinois, nous présentons, selon notre jugement, les services mobiles et des applications que sont convenables pour la Chine. Parmi eux, nous pensons qu'il y a la tendance sur les services basés sur la localisation et services orientées de l'architectures. Cette tendance peut attirer plus d'attention à offrir de nouveaux services. En plus, elle peut offrir des services d'intégration et de personnalisation qui viennent de fournisseurs de services mobiles et des utilisateurs finaux. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Gestion intégrée et écosystémique, Principe de précaution, Communication entre acteurs, Risques sur l'environnement et la santé.

In the future, robots will expand from industrial and research applications to the home. Domestic service robots will work in the home to perform useful tasks such as object retrieval, cleaning, organization, and security. The tireless support of these systems will not only enable able bodied people to avoid mundane chores; they will also enable the elderly to remain independent from institutional care by providing service, safety, and companionship. Robots will need to understand the relationship between objects and their environments to perform some of these tasks. Structured indoor environments are organized according to architectural guidelines and convenience for their residents. Utilizing this information makes it possible to predict the location of objects. Conversely, one can also predict the function of a room from the detection of a few objects within a given space. This thesis introduces a framework for combining object permanence and context called the probabilistic cognitive model. This framework combines reasoning about spatial extent of places and the identity of objects and their relationships to one another and to the locations where they appear. This type of reasoning takes into account the context in which objects appear to determine their identity and purpose. The probabilistic cognitive model combines a mapping system called OmniMapper with a conditional random field probabilistic model for context representation. The conditional random field models the dependencies between location and identity in a real-world domestic environment. This model is used by mobile robot systems to predict the effects of their actions during autonomous object search tasks in unknown environments.

This essay presents a survey that was conducted on 52 college students regarding their opinions on advertisement received to the mobile phone. The questionnaire survey focused on what college students think of advertising to the mobile phone and what attitude they have towards it. The thoughts behind this study are that advertisement to the mobile phones is something that is getting more popular when the mobile phone is getting more advanced. The result of the study showed that college students are not that interested in receiving advertisement to their mobile phones. Several of the college students that participated in the study already get advertisement to their mobile phones, advertisement that they don't want because it doesn't reflect their interests. The study showed that if the advertisement sent to the respondents was to get more customized to their personal interest they might consider receiving it.

This research aims at analysing how the usage of Facebook differs on mobile phones and computers from the view of an end user. 10 people were consulted in semistructured interviews about their individual usage. Topics of the interviews included the amount of time they spend on Facebook on their mobile phones and how often, why they are using it on this device and when they rather use a computer. The results of the interviews indicate that people mostly use their mobile phone on their every-day journeys, esp. while they use public transport and they are bored waiting for or beeing on the means of transport. Often they just check the Newsfeed to see what their friends are doing. They mainly want to be informed about the activities of their friends, therefore, produce less content themselves on Facebook Mobile rather than on their computer. The questioned users do not have the feeling they need to log in on Facebook, instead they do it subconsciously all the time. The small screen and keypad on the mobile phone are still the main reasons why the usage of Facebook on the computer is more convenient. Nevertheless, because Facebook on the mobile phone is limited in its features it also offers a good overview. The non-available features on mobile devices are simply not missed and for this reason not even used on the Facebook computer version. However, if a function should be executed, which does not exist on the mobile phone the users are waiting until they can access a computer but possibly they forget about it by then and the importance of the accomplishment disappears.

Mobile Advertising is considered to be an unlimited industry in business opportunities, and the relative chain in Taiwan has become mature. When the technology has improved a lot, we should come up with a business model to maximize the potential of mobile advertising. This article focus on the factor of mobile acceptance, and analysis the relationship between acceptance and advertising effect. Also, we observe the effects of involvement and the structure of mobile advertising. We obtained some conclusions as following. 1. The factors that affect mobile advertising are utility, context, the sacrifice of controlling, the cost of receiving and the degree of trust. Especially we view context and the degree of trust are the most important factors of all. 2. The acceptance of mobile advertising will affect the attitude towards advertising, the attitude towards brand and the intention of purchasing.3. The adjust function of involvement between acceptance and advertising effects is not significant. 4. The adjust function of the structure of mobile advertising between acceptance and advertising effects is also not significant.

In recent years, with the popularization of the mobile devices, more and more location-based applications have been developed. As a result, location data of various objects is widely available. Identifying object groups that tend to move together is an emerging research topic. Existing approaches for identifying mobile group patterns assume the existence of raw location data which records a given object¡¦s position at every equal-spaced time point. However, a moving object may become disconnected voluntarily or involuntarily from time to time, and thus this assumption may not always valid. In this research, we describe the locations of moving object as a (non-continuous) trajectory function. Based on the new model, we re-define the mobile group mining problem and develop efficient algorithms for mining mobile groups. The proposed algorithms are evaluated via synthetic data generated by IBM City Simulator.

This research aims to construct a brand-new teaching and learning environment called Transportable Digital Learning Center (TDLC) which contains three important features: mobility, ready-made and self-contained features. TDLC is constructed for providing learning opportunities to (a) people in disaster areas with a temporary teaching and learning environment before their reconstructions finished; (b) people in undeveloped countries who do not have learning opportunities due to the lack of financial resources; (c) people in geographically isolated places like deserts or high mountain areas who do not have learning opportunities due to the isolation of their geographic locations. The mobility feature means that it can be transported to different geographic locations easily; The ready-made feature means that all the components of a TDLC such as access point, TDLC Server, power supply, Tablet PCs and charging devices used to provide a teaching and learning environment are all equipped inside the TDLC in advance; Self-contained feature means that it is unnecessary to provide it with any other resources like network connections and electricity to sustain its operation. Therefore, once a TDLC has been transported to its destination, it can be used to conduct teaching and learning activities immediately. In this paper, we describe the overall concepts, main components, system design and implementation, and teaching & learning activity design of TDLC. We also conducted an experimental English Situated Learning activity to evaluate the effects of using TDLC in the teaching and learning activity. Finally, some future research topics of TDLC are proposed.
