Principalmente el proyecto se centra en la personalización gráfica del interfaz y en el desarrollo de un plugin que añada la funcionalidad de permitir a un usuario cambiar la fotografía de su perfil en una instalación Moodle.

Means and challenges in international operations for a Finnish mobile application provider

Master’s Thesis concentrates to means and challenges in international operations for a Finnish mobile application provider Small Planet Oy during its various company stages from founding till maturing and during macro economical phases between year 1998 and 2008. Small Planet has just celebrated its 10 year anniversary and is therefore quite an extraordinary company which has survived all the highs and lows during past ten years and which has operated in the market as long as the whole mobile application industry has existed. Master’s Thesis describes possibilities for a company’s internationalization with different entry modes like exporting, licensing, investment entry and co-operative operations which are suitable for a mobile application provider. Unsuitable entry modes like franchising or contract manufacturing are not explained. The goal has been to analyze Small Planet’s international operations and to make conclusions from the practical experiences. Analysis and conclusions shall help Small Planet in its international operations in the future and should give insight to other mobile application companies and their managers who are in the situation of planning their own international operations. Results show that the best ways for Small Planet to internationalize its operations has been the co-operation with a big domestic client and the co-operation with Finnish operator infrastructure providers which have complementary products with Small Planet. Through these co-operations Small Planet has got lot of new international clients. Same time financial risks and investment need for international operations have been low. Co-operative international sales can be the most efficient international entry mode for a mobile application provider.

Handover aspects in Unlicensed Mobile Access Technology

Fixed Mobile Convergence is the recent buzz in the field of telecommunication technology. Unlicensed Mobile Access (UMA) technology is a realistic implementation of Fixed Mobile Convergence. UMA involves communication between different types of networks. Handover is a very important issue in UMA. The study is an analysis of theoretical handover mechanism and practical test results. It includes a new proposal for handover performance test in UMA. It also provides an overview of basic handover operation on different scenarios in UMA. The practical test involves an experiment on handover performance test using network analyzers. The new proposal provides a different approach for an experimental setting on handover performance test without using network analyzers. The approach is not be implemented because of some technical problem in a network equipment in UMA. The analysis of the test results reveals that time of handover between UMA and Global System for Mobile Communication (GSM) network is similar to time of handover between inter base station controller (BSC) handover in GSM networks. The new approach is simple and provides measurement at the end point communicating entities. The study gives a general understanding of handover operation, an analysis of handover performance in UMA and specifically provides a new approach useful for further study of handover in different real world environments and scenarios.

Análisis del entorno colaborativo creado para una experiencia de mobile learning

Se presentan los resultados de una investigación sobre las concepciones y usos de dispositivos móviles de un grupo de estudiantes que trabajaron en un entorno de aprendizaje colaborativo como parte un proceso de e-learning. Se emplearon dos métodos de investigación, en primer lugar el análisis del contenido de los mensajes de un foro de discusión enviados durante todo el curso, para recoger datos acerca del uso y la valoración que hacían del proceso de mobile learning. Posteriormente, mediante las entrevistas en profundidad, se analizó la percepción de mobile learning y los cambios producido durante el curso en el entorno colaborativo de aprendizaje. Los resultados indican que el entorno de intercambio creado amplifica la participación y colaboración entre los alumnos en el proceso de mobile learning, favoreciendo un mayor protagonismo de los estudiantes en una experiencia de aprendizaje online.

Landslide detection and monitoring capability of boat-based mobile laser scanning along Dieppe coastal cliffs, Normandy

Integrated in a wide research assessing destabilizing and triggering factors to model cliff dynamic along the Dieppe's shoreline in High Normandy, this study aims at testing boat-based mobile LiDAR capabilities by scanning 3D point clouds of the unstable coastal cliffs. Two acquisition campaigns were performed in September 2012 and September 2013, scanning (1) a 30-km-long shoreline and (2) the same test cliffs in different environmental conditions and device settings. The potentials of collected data for 3D modelling, change detection and landslide monitoring were afterward assessed. By scanning during favourable meteorological and marine conditions and close to the coast, mobile LiDAR devices are able to quickly scan a long shoreline with median point spacing up to 10cm. The acquired data are then sufficiently detailed to map geomorphological features smaller than 0.5m2. Furthermore, our capability to detect rockfalls and erosion deposits (>m3) is confirmed, since using the classical approach of computing differences between sequential acquisitions reveals many cliff collapses between Pourville and Quiberville and only sparse changes between Dieppe and Belleville-sur-Mer. These different change rates result from different rockfall susceptibilities. Finally, we also confirmed the capability of the boat-based mobile LiDAR technique to monitor single large changes, characterizing the Dieppe landslide geometry with two main active scarps, retrogression up to 40m and about 100,000m3 of eroded materials.

Urbanités marchandes : le commerce dans la production de la qualité urbaine et ses régulations : le cas de Lausanne

While collective identity markers are constantly evolving in today's city, the hyper-consumption society has allowed retail, even though greatly transformed, to remain a community hub for socialization. Society's commodification takes shape precisely within the public realm and the urban scene: sprawling analogous drivable retail-only suburbs and turning city centers into bland, soulless and undefined places displaying homogeneous frontages characterized by the same retail storefronts worldwide. More than ever, urban policies on retail oriented servicescapes seem crucial to urban and regional planning from a sustainable perspective. Thorough the study case of Lausanne, our research focuses on how the urban planning model and its policies could set into place spatial strategies to enhance urban quality and to reorganize retail centralities without succumbing to the prevailing commodification of the public realm. -- Les indicateurs d'identité collective se reformulent dans la ville actuelle, mais la société de l'hyperconsommation a permis au commerce, aussi transformé soit-il, de rester un lieu d'échange et de brassage social. La marchandisation de la société prend des formes précises dans l'espace et a un impact certain sur le paysage urbain : multipliant les espaces marchands périphériques monofonctionnels ou encore transformant nos centres-villes en paysages anodins, présentant des vitrines semblables quel que soit le pays où elles se situent. Plus que jamais, une régulation des espaces de consommation semble incontournable pour l'aménagement du territoire et l'urbanisme dans une perspective de durabilité. À travers le cas lausannois, cette thèse s'interroge sur la façon dont les modèles urbanistiques de régulation des jeux d'acteurs privés peuvent participer à la mise en place de stratégies de qualification urbaine et d'organisation des centralités commerciales sans céder à la tentation de la marchandisation des espaces publics.

An integrated model of adoption and development of e-commerce in companies

Since the mid-1990s researchers have sought to understand why some firms embark on e-commerceoperations on the Internet while others prefer to wait and see how events unfold. We still have todetermine which variables contribute to explaining the extent to which firms use e-commerce, giventhat to date the literature has not yet offered conclusive evidence on this question. The current workaims to provide an integrated vision of the set of factors influencing the e-commerce adoptionprocess. We use a sample of 2,038 firms of all types that trade their products either with otherorganizations or with end-consumers.
