Повний текст джерелаFuture pervasive environments will take into consideration not only individual user’s interest, but also social relationships. In this way, pervasive communities can lead the user to participate beyond traditional pervasive spaces, enabling the cooperation among groups and taking into account not only individual interests, but also the collective and social context. Social applications in CSCW (Computer Supported Cooperative Work) field represent new challenges and possibilities in terms of use of social context information for adaptability in pervasive environments. In particular, the research describes the approach in the design and development of a context.aware framework for collaborative applications (CAFCA), utilizing user’s context social information for proactive adaptations in pervasive environments. In order to validate the proposed framework an evaluation was conducted with a group of users based on enterprise scenario. The analysis enabled to verify the impact of the framework in terms of functionality and efficiency in real-world conditions. The main contribution of this thesis was to provide a context-aware framework to support collaborative applications in pervasive environments. The research focused on providing an innovative socio-technical approach to exploit collaboration in pervasive communities. Finally, the main results reside in social matching capabilities for session formation, communication and coordinations of groupware for collaborative activities.
O futuro dos ambientes pervasivos irá levar em consideração não só os interesses individuais dos utilizadores, mas também as relações sociais. Desta forma, a participação em comunidades pode levar o utilizador para além da experiência em espaços tradicionais pervasivos, permitindo a cooperação entre grupos e tendo em conta não só os intresses individuais, mas também o contexto coletivo e social. Aplicações sociais na área de CSCW (Computer Supported Cooperative Work) representam novos desafios e possibilidades em termos do uso da informação social de contexto para a adaptação e personalização em computação pervasiva. Esta tese explora o potencial da utilização consciente do contexto e das informações sociais em aplicações CSCW, a fim de apoiar a colaboração em ambientes pervasivos. Em particular, a investigação descreve a abordagem do design e desenvolvimento de um framework consciente do contexto para aplicações colaborativas (CAFCA), utilizando-se das informações de contexto e sociais dos utilizadores para adaptações proactivas em ambientes pervasivos. A fim de validar o framework proposto, uma avaliação foi realizada com um grupo de utilizadores, com base num cenário empresarial. A análise permitiu verificar o impacto do framework em termos de funcionalidade e eficiência em condições do mundo real. A principal contribuição deste trabalho foi desenvolver um framework contexto-aware para suportar aplicações de colaboração em ambientes pervasivos. A investigação centrou-se em uma abordagem sociotécnica inovadora de explorar a colaboração em comunidades. Os principais objetivos residem na capacidade social para formação de sessões, a comunicação e coordenação de groupware para atividades colaborativas.

Повний текст джерелаIn this thesis, we address two issues in the area of decentralized distributed systems: network-aware overlays and collaborative editing. Even though network overlays have been extensively studied, most solutions either ignores the underlying physical network topology, or uses mechanisms that are specific to a given platform or applications. This is problematic, as the performance of an overlay network strongly depends on the way its logical topology exploits the underlying physical network. To address this problem, we propose Fluidify, a decentralized mechanism for deploying an overlay network on top of a physical infrastructure while maximizing network locality. Fluidify uses a dual strategy that exploits both the logical links of an overlay and the physical topology of its underlying network to progressively align one with the other. The resulting protocol is generic, efficient, scalable and can substantially improve network overheads and latency in overlay based systems. The second issue that we address focuses on collaborative editing platforms. Distributed collaborative editors allow several remote users to contribute concurrently to the same document. Only a limited number of concurrent users can be supported by the currently deployed editors. A number of peer-to-peer solutions have therefore been proposed to remove this limitation and allow a large number of users to work collaboratively. These decentralized solution assume however that all users are editing the same set of documents, which is unlikely to be the case. To open the path towards more flexible decentralized collaborative editors, we present Filament, a decentralized cohort-construction protocol adapted to the needs of large-scale collaborative editors. Filament eliminates the need for any intermediate DHT, and allows nodes editing the same document to find each other in a rapid, efficient and robust manner by generating an adaptive routing field around themselves. Filament's architecture hinges around a set of collaborating self-organizing overlays that utilizes the semantic relations between peers. The resulting protocol is efficient, scalable and provides beneficial load-balancing properties over the involved peers

Повний текст джерелаSingapore and many parts of Asia were hit with Severe Acute Respiratory Syndrome (SARS) in March 2003. The spread of SARS lead to a rapidly deteriorating and chaotic situation. Because SARS was a new infection, there was no prior knowledge that could be referenced to tackle such a complex, unknown and rapidly changing problem. Fortunately, through sound measures coupled with good leadership, quick action and inter-agency cooperation, the situation was quickly brought under control. This thesis uses the SARS incident as a case study to identify a set of network centric warfare methodologies and technologies that can be leveraged to facilitate the understanding and management of complex and rapidly changing situations. The same set of methodologies and technologies can also be selectively reused and extended to handle other situations in asymmetric and unconventional warfare.

Повний текст джерелаHow can we become more aware of the sources of insight within human organisations? Rapid economical and technological changes force organisations to become more adaptive, agile and interdisciplinary. In light of this, organisations are seeking alternatives for traditional hierarchical communication structures that hinder bottom-up collaboration practices. Effective bottom-up methods require empowering members with access to the information and expertise they need to take qualified decisions. This is a complex challenge that involves organisational culture, IT and work practices. Failing to address it creates bottlenecks that can slow down business processes, hinder innovation and often lead to suboptimal and redundant work. For example, a 2014 survey of 152 Campus IT leaders in the US, estimated that 19% of the campus IT systems are redundant, costing US universities 3.8B$ per year. In aggregate, knowledge workers find the information they need only 56% of the time. With a quarter of knowledge workers total work time spent in finding and analyzing information. This time waste alone costs 7K$ per employee annually. Another example of the waste created is that newcomers and remote employees may take up to 2 years to fully integrate within their department. Furthermore according to extended surveys, only 28% of millennials feel that their current organizations are making ‘full use’ of the skills they currently have to offer and 66% expect to leave their organisation by 2020. Successfully resolving this challenge holds the potential to motivate organisation members, as well as enhance innovation and learning within it. The focus of this thesis is to better understand this problem by exploring the challenges faced by a university IT department and an interdisciplinary research center. Second, co-develop and implement a solution with these institutions, I describe their usage of the software tool we developed, outcomes and value obtained in these pilots. Third, test the effectiveness of the solution, and explore further applications and potential for a similar system to be used in a wider scale. To better understand the problem I engaged in discussion with members and leaders of both organisations. An important conclusion from the discussions is that members of these organizations often suffer from lack of awareness about their organisation’s knowledge capital—the competencies, knowledge of processes and social connections of their colleagues. Due to this exposure to innovative ideas, opportunities and common interests of peers is severely limited. This causes unnecessary delays in inter-team projects, bottlenecks, and lack of awareness about internship opportunities. I further broke down the problem, and defined it as one of information fragmentation: Different information is stored in disparate databases or inside people’s heads, requiring effort and know-how in order to obtain it. Following the conclusions of this analysis and state-of-the-art review, we have set together the goal to create a collaborative visual database to map the people, projects, skills and institutions for the IT department of Descartes University, and in addition, people, interests and internship opportunities within the CRI, an interdisciplinary research and education center. We have also conducted interviews, surveys and quizzes that ascertain that people had difficulties identifying experts outside their core teams. During the course of this thesis, I progressively addressed this challenge by developing two collaborative web applications called Rhizi and Knownodes. Knownodes is a collaborative knowledge graph which utilized information-rich edges to describe relationships between resources. Rhizi is a real-time and collaborative knowledge capital mapping interface. A prominent unique feature of Rhizi is that it provides a UI that turns text-based assertions made by users into a visual knowledge graph. (...)

Kao, Yi-Hsuan. "Optimizing task assignment for collaborative computing over heterogeneous network devices." Thesis, University of Southern California, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10124490.
Повний текст джерелаThe Internet of Things promises to enable a wide range of new applications involving sensors, embedded devices and mobile devices. Different from traditional cloud computing, where the centralized and powerful servers offer high quality computing service, in the era of the Internet of Things, there are abundant computational resources distributed over the network. These devices are not as powerful as servers, but are easier to access with faster setup and short-range communication. However, because of energy, computation, and bandwidth constraints on smart things and other edge devices, it will be imperative to collaboratively run a computational-intensive application that a single device cannot support individually. As many IoT applications, like data processing, can be divided into multiple tasks, we study the problem of assigning such tasks to multiple devices taking into account their abilities and the costs, and latencies associated with both task computation and data communication over the network.
A system that leverages collaborative computing over the network faces highly variant run-time environment. For example, the resource released by a device may suddenly decrease due to the change of states on local processes, or the channel quality may degrade due to mobility. Hence, such a system has to learn the available resources, be aware of changes and flexibly adapt task assignment strategy that efficiently makes use of these resources.
We take a step by step approach to achieve these goals. First, we assume that the amount of resources are deterministic and known. We formulate a task assignment problem that aims to minimize the application latency (system response time) subject to a single cost constraint so that we will not overuse the available resource. Second, we consider that each device has its own cost budget and our new multi-constrained formulation clearly attributes the cost to each device separately. Moving a step further, we assume that the amount of resources are stochastic processes with known distributions, and solve a stochastic optimization with a strong QoS constraint. That is, instead of providing a guarantee on the average latency, our task assignment strategy gives a guarantee that p% of time the latency is less than t, where p and t are arbitrary numbers. Finally, we assume that the amount of run-time resources are unknown and stochastic, and design online algorithms that learn the unknown information within limited amount of time and make competitive task assignment.
We aim to develop algorithms that efficiently make decisions at run-time. That is, the computational complexity should be as light as possible so that running the algorithm does not incur considerable overhead. For optimizations based on known resource profile, we show these problems are NP-hard and propose polynomial-time approximation algorithms with performance guarantee, where the performance loss caused by sub-optimal strategy is bounded. For online learning formulations, we propose light algorithms for both stationary environment and non-stationary environment and show their competitiveness by comparing the performance with the optimal offline policy (solved by assuming the resource profile is known).
We perform comprehensive numerical evaluations, including simulations based on trace data measured at application run-time, and validate our analysis on algorithm's complexity and performance based on the numerical results. Especially, we compare our algorithms with the existing heuristics and show that in some cases the performance loss given by the heuristic is considerable due to the sub-optimal strategy. Hence, we conclude that to efficiently leverage the distributed computational resource over the network, it is essential to formulate a sophisticated optimization problem that well captures the practical scenarios, and provide an algorithm that is light in complexity and suggests a good assignment strategy with performance guarantee.

Avec les cas qui comprennent les protocoles du Web sémantique, Google PageRank et les services de filtrage par collaboration, l'oeuvre déterre certains engagements clés intellectuelle dans les technologies, qui indiquent comment chacun des technologies construit le rationalité sociale à travers son processus de calcul. Les cas ont été choisis parmi ceux des outils numériques de plus en plus invoquée pour coordonner l'action dans la vie quotidienne: pour l'organisation de gens, le savoir et les institutions de diverses manières, pour le fonctionnement de grandes bureaucraties et les institutions, pour les mécanismes de rétroaction dans l'économie en réseau, et comme formats nouveaux pour la communication sociale quotidienne entre amis, famille et collègues. Pour comparer les cas, le projet de recherche décrit plusieurs formes de la rationalité philosophique: instrumental de l'objet visé, économique, communicative et socio-techniques. Cela permet de souligner à son tour trois aspects de l'informatique sociale: comment les conditions de validité épistémique et de 'action réussie' sont encodés dans des algorithmes logiciels et les protocoles ; la façon dont chacun des modèles de cas technologie rationnelle parvenus à un consensus par une certaine configuration de la sémantique et pragmatique du langage ; et comment des interactions sociaux sont inscrit de façon distribuée, pour potentialiser les conditions de leurs fonctionnement.

Notre approche permet la composition et l'évaluation des fonctions d‘un système de cache collaboratif de haut niveau de façon flexible. Notre proposition est basée sur un modèle multicouche qui définit les fonctions principales d'un système de cache collaboratif pour les grilles. Ce modèle et la spécification fournie sont utilisés pour construire une infrastructure logicielle flexible et générique pour l'opération et le contrôle du cache collaboratif. Cette infrastructure est composée d'un groupe d’éléments autonomes de cache appelés "Grid Cache Services" (GCS). Le GCS est un administrateur local de moyens de stockage et de données temporaires. Nous étudions une possible configuration d’un groupe de GCS qui constitue un système basique d'administration de données temporaires appelé "Temporal Storage Service" (TSS)

Повний текст джерелаThis research was inspired by the need to create a universal net-centric environment to enable collaborative defense capabilities and deliver knowledge dominance to the DoD. Since superior information management and the use of collaborative IT technologies is fundamental to building intelligence capabilities, this study aims to contribute to the optimization of collaborative system use by military groups and organizations. The proposed research model illustrates and explains the direct relationships between collaborative IT competence and collaborative functionalities, which can be used not only to assess current technologies but also aid in requirements generation for designing the ideal collaborative tool suite. Central to the research model we introduce the concept of collaborative IT competence, defined as the effective use of collaborative functionalities, and explore its relationship to performance outcomes. Having pre-tested and validated the proposed research model by means of empirical data collection in the form of an end-user survey instrument we recommend further research be conducted on a Navy-wide scale to evaluate the 181 collaborative technology tools currently in use. End-user/warfighter insight will dramatically influence future CIT investment decisions by providing decision makers critical information regarding the pragmatic versus the advertised attributes of the application/tool suite. Additionally, this model is designed to provide the road map to the ideal combination of core functionalities and required collaborative IT competence.

Повний текст джерелаThis thesis work contributes both in the pervasive computing and computer supported collaborative work domains. We explore these domains by an extended presentation of related works concerning models, designs and evaluation methods. Our main contribution for these areas is the PCSCW model, which proposes an original approach to the integration of the pervasive aspect inside the collaboration. By relying on an ontological model representing users’ context and a set of devices collaboration rules, our work enables smart devices to analyse their context and find the best way to behave and collaborate with other devices of the environment in order to seamlessly and efficiently channel and facilitate the collaboration of humans. We also propose a methodology allowing collaborative systems’ developers to build their own evaluation strategies

Повний текст джерелаResearch has shown that collaborative eLearning can provide educational opportunities to groups of learners; both distance learners as well as traditional campus-based learners. It provides innovative educational methods in which learning can be constructed. The way collaborative eLearning is administered, managed, used and adopted can assist in providing information for future design and improvement of collaborative software. The objective of this research is to provide an insight into adoption and use of collaborative eLearning environments and to discover new determinants of usage. To examine the usage of an eLearning environment at the University of the Western Cape, a cross-sectional survey was conducted with Computer Science students. While this study is specific to this university, the underlying principles can be generalised to other organisational types. This study is quantitative and qualitative in nature as well as deductive and inductive. Three hundred and six valid questionnaires were analysed using quantitative methods. Soft Systems Methodology was used to manage the research process and to create conceptual models to explain the research problem and identify solutions. It was a cyclical process. Findings show that although the university’s eLearning platform is utilised, students seem to prefer free and open source platforms. They use social and collaborative applications such as WhatsApp, Telegram, Dropbox, Google Drive, Google Docs as well as email messages. Four types of technology affordances: communicative-affordance, document share-affordance, course resource-affordance, and integrity-affordance were identified as being relevant in their choice of application. Furthermore, culture—masculinity/femininity, individualism/collectivism, Uncertainty Avoidance, and Power Distance—also have an effect on the adoption of collaborative eLearning applications and software the students used for learning. Chi-Square analysis found that individualism/collectivism and Power Distance were both significant and related to the adoption and usage of collaborative eLearning. Gender was found not to be a determinant of how students view the use of collaborative eLearning software applications. Finally, it was also found that understanding use and user behaviour, could provide the theoretical guidance to inform collaborative eLearning design. The analysis and findings show that culture influences the adoption of collaborative eLearning while technology affordance plays a major role in the use of collaborative eLearning.
