Žinant, kad versle, norint sėkmingai gyvuoti, reikia iškelti sau – organizacijai tam tikrus tikslus ir uždavinius. Tačiau, kartais, norint pasiekti užsibrėžtų tikslų, ne visuomet užtenka įprastinių verslo priemonių, tenka ieškoti naujų, praktiškesnių ir naudą teikiančių priemonių. Todėl siekiama išsiaiškinti, kokiose verslo srityse galima pritaikyti hibridinių aplikacijų integraciją įmonių informacinėse sistemose, siekiant optimizuoti vykdomus procesus. Šio darbo analizės dalyje ištirta ir išsiaiškinta kokia yra hibridinių aplikacijų technologija, ištirta hibridinių aplikacijų architektūra, veikimo principas bei galimi tokių aplikacijų panaudos ir pritaikymo sprendimai, leidžiantys suprasti ir įvertinti, kaip galima pritaikyti šią technologiją verslo srityje. Eksperimentinėje dalyje atlikti trys skirtingi eksperimentai, įvertinant hibridinių aplikacijų pritaikymo ir integravimo galimybes versle, taikant tiek komercinius tiek „Atviro kodo“ kūrimui skirtus įrankius. / It is a well known fact that in order to function successfully the organization has to have set goals. Sometimes while trying to achieve them the usual business means are not enough and new, more efficient ways have to be found. Considering this, it is important to find out the potential business areas in which the integration of hybrid applications can be applied in order to optimize the processes. The analysis part of this paper investigates the technology of hybrid applications, examines their architecture, the principle of operating, possible usage and the possibilities of applying them, all these factors helping understand and evaluate how this technology can be used in business. The experimental part of this paper describes three different experiments concerning the evaluation and integrating of hybrid applications in business while applying both commercial tools and those designed for creating Open-Source.

Mashups—texts composed by combining portions from several original texts—are a new literary form. In order to better understand this form, I have created my own literary mashup, Buchstauben, which allowed me to encounter first-hand the nuances of the form. As such, my thesis consists of both my own literary mashup, Buchstauben, as well as a critical component, in which I explore the history of the mashup, from the Classic poetic technique of the cento to the modern work of mashup artists such as Girl Talk. The critical component also serves as a reflection on my own experiences in composing a mashup, and the challenges this form poses to mashup artist, especially in light of contemporary copyright concerns.

This thesis document articulates the development of Dance/Video Mashup as a Choreographic Process. Prior to this movement thesis I determined a list of goals I would aim to achieve throughout the exploration of Dance/Video Mashup as a Choreographic Process. The goals aimed to develop a choreographic process that sampled movement from videos found online, create a website that documented the creative process of developing a screendance, realize an artistic need and develop clear guidelines for future choreographers. This document narrates and evaluates the creative process of developing guidelines for Dance/Video Mashup and clearly articulates the guidelines for future researchers and choreographers. The supplemental file attached allows readers to view the screendance, Somniloquies, created through Dance/Video Mashup as a Choreographic Process.

In order to realize effective infotainment systems for vehicles, we need to have context-aware applications that use the latest (live) information for an enhanced user experience. Such up-to-date information is now abundantly available on the Internet, due to the explosive growth of the Web 2.0. In earlier times, it was difficult and expensive for vehicles to connect to the Internet. Recent advances in vehicular ad-hoc networks (VANETs) have enabled vehicles to connect to the Internet through road side infrastructures, with little to no additional cost. However, there are several problems with directly using Internet data in a vehicle, such as (1) Internet data sources have their own interfaces, which keep changing over time, needing frequent application updates, (2) information provided by multiple data sources needs to be preprocessed and fused before use, and (3) vehicles employ propriety platforms for infotainment systems, which makes an application update even more cumbersome. Furthermore, accessing multiple Internet sources may cause unnecessary overhead over the VANET bandwidth. In this thesis, we propose a cloud-based middleware framework for vehicular infotainment application development. The proposed framework follows service oriented architecture in which data filtering and fusion functionalities are delegated to the cloud. Data filtering and fusion reduce the data flow over VANET. Furthermore, because most the the processing is done on the cloud, the client becomes lightweight and loosely coupled with Internet resources and underlying platforms. We also propose a class based fusion method to combine information from multiple sources. The efficacy of the proposed framework is validated by developing an enhanced navigation (eDirection) application for the vehicle, as well as three infotainment applications: context-aware music, news, and weather.

This project explores the question of originality and appropriation in the creative world by using mashup video as a medium. How can old repetitive stories be deconstructed and transformed into something new? I have created alphabetically ordered montages of shots/scenes containing words/letters from superhero films. By doing so, I do not provide a concrete answer to what is really original in today’s world, but rather encourage the audience to actively participate in the viewing experience of the carefully structured ontology and see the infinite possibility of the modern-day mashup culture.

Information technologies have achieved an important role in archaeology. The management, research and exchange of the large amount of data gathered from archeological sites needs the tools of information technologies. The web based GIS combines the advantages of both GIS and the Internet technologies. This system can be used as a tool that helps to support the management of information for archaeological sites and provides support functions for specialists.This web based system can hold many types of archaeological site data from small excavation campaigns to large sites. The system consists of a relational database, a web server, and a GIS mapping server. Google Maps Server is used as a GIS mapping server in this study. The client computers require only the availability of a proper browser that supports javascript and ajax technologies. With this system, Google Maps can be used as an archaeological research tool for everybody interested in archaeology. In a general, everybody can reach the system using their web browsers in order to search and retrieve information regarding archaeological sites. This system also enables specialists to upload, search and share archaeological data. The aim of this study is to provide easy and simple access to the GIS related archaeological site information in Turkey, using a web based and user friendly interface and share the information the information with specialists all over the world.

Owing to a recent online trend of web 2.0, societies have emerged not only culturally but also technologically/virtually. This coupled with semantic web and Web Services have provided end-users with more opportunities to contribute to the web and consequentially have also multiplied their digital needs. One such requirement of a modern-day end-user is to combine the data, view and/or process presented across the web to suit his/her ephemeral needs by developing a novel application known as a service mashup. The end user development of mashup poses significant challenges to the end users. First challenge addressed in this thesis is the scope vs complexity challenge which refers to the impossibility of fully eliminating the technical barrier between a tool and the end user due to the corresponding complexity creeping in while developing new features in tool and extending its scope to provide added functionality. The second challenge arises from the utility=value/effort equation which implies that effort required in developing a mashup decreases the value and hence neutralizes the utility. Given these challenges and the related issues, I made three contributions. The central theme of my proposed approach - for managing these inherent challenges - is that the end user must be integrated into the process of a service composition application. My approach - A Goal-Oriented Mashup Development (GO-MaDe) framework defines, organizes and addresses the problems faced by end-users while composing their applications by proposing a new style of development in the mashup area in a bid to render irrelevant the underlying inherent tensions of the paradigm. My first contribution in this regard is a classification model that takes into account end user centered usability criteria for calibrating mashup tools efforts. Secondly, this research is the pioneer study about the integration of an agile-style analysis-cum-design phase into the mashup development process. Hence, it presents a redefined process of service-based applications development by introducing a spiral process model that introduces a phased, incremental concept of mashup development lifecycle. Based on the spiral model, I have presented a method (KAReM) annotated with domain theory for better acquisition and representation of user requirements encompassed by the APIs or Web Services that are composed to develop a mashup by incorporating the dynamics of goal decompositions using goal based templates. It serves to enhance the end-user experience by facilitating them to explore the problem space and helping them derive the visual representations of their requirements which can then be translated into service compositions. To evaluate my contributions qualitatively and quantitatively I conducted literature reviews, and validated my framework by scenarios and a controlled experiment.

This research achieves two main goals: First it proposes a set of extensions to the existing Opencast Matterhorn lecture video capture system, which should enhance its effectiveness and enable the collection of fine-grained datasets for further research. These extensions allow users to quickly and easily create, find, tag, annotate, and share `clipshows' of their video recorded classes both publicly and privately. Second, the tracking data generated when users create or view the clipshows using these extensions are used to analyze the efficacy of the system.

Cette thèse présente MELQART, un système d'exécution de mashups avec disponibilité de données. Un mashup est une application web qui combine des données provenant de fournisseurs hétérogènes (web services). Ces données sont agrégées pour former un résultat homogène affiché dans des composants appelés mashlets. Les travaux dans le domaine des mashups, se sont principalement intéressés au fonctionnement des mashups, aux différents outils de construction et à leur utilisation et interaction avec les utilisateurs. Dans cette thèse, nous nous intéressons à la gestion de données dans les mashups et plus particulièrement à la disponibilité et la fraîcheur de ces données. L'amélioration de la disponibilité tient compte du caractère dynamique des données des mashups. Elle garantit (1) l'accès aux données même si le fournisseur est indisponible, (2) la fraicheur de ces données et (3) un partage de données entre les mashups afin d'augmenter la disponibilité de données. Pour cela nous avons défini un modèle de description de mashups permettant de spécifier les caractéristiques de disponibilité des données. Le principe d'exécution de mashups est défini selon ce modèle en proposant d'améliorer la disponibilité et la fraicheur des données du mashup par des fonctionnalités orthogonales à son processus d'exécution. Le système MELQART implante ce principe et permet de valider notre approche à travers l'exécution de plusieurs instances de mashups dans des conditions aléatoires de rupture de communication avec les fournisseurs de données. / This thesis presents MELQART: a mashup execution system that ensures data availability. A mashup is a Web application that application that combines data from heterogeneous provides (Web services). Data are aggregated for building a homogenous result visualized by components named mashlets. Previous works have mainly focused, on the definition of mashups and associated tools and on their use and interaction with users. In this thesis, we focus on mashups data management, and more specifically on fresh mashups data availability. Improving the data availability take into account the dynamic aspect of mashups data. It ensures (1) the access to the required data even if the provider is unavailable, (2) the freshness of these data and (3) the data sharing between mashups in order to avoid the multiple retrieval of the same data. For this purpose, we have defined a mashup description formal model, which allows the specification of data availability features. The mashups execution schema is defined according to this model with functionalities that improve availability and freshness of mashed-up data. These functionalities are orthogonal to the mashup execution process. The MELQART system implements our contribution and validates it by executing mashups instances with unpredictable situations of broken communications with data providers.
