    It is estimated that by the year 2010, the number of people over 65 years of age will reach 39 million. By 2030, that number is expected to over 70 million individuals in the 85 and older age group making them the fastest growing group of older individuals. Their growth rate is three times more than all of the 65 and older age groups put together. Falls and mobility issues are very common among ol... View full abstract»

    Service-oriented computing (SOC) is the computational paradigm that utilizes services as fundamental elements to develop applications/solutions. To build a service model, SOC relies on the service-oriented architecture (SOA), which is a way of reorganizing software applications and infrastructures in a set of interacting services. This paper proposes an architectural model that separates in layers... View full abstract»

    Currently, there is a lack of tools to build autonomous software systems in a pervasive and distributed context. In this paper, we present a model and a development tool called Agentphi for building flexible agent architectures from fine-grained components. Reusable components implement non-functional mechanisms such as communication, mobility or adaptation skills. Each agent can dynami... View full abstract»

    We report on an empirical study performed in an industrial environment in which the impact of modifying test practices is measured. First, the efficiency of the existing test practices is measured, by analyzing the software defects using a modified version of Orthogonal Defect Classification (ODC). The study was conducted in two phases lasting seven months each. In the first phase (Phase A), defec... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (225 KB) | HTML iconHTML

    OPScript is a statically typed object oriented language, created to be executed as client code in Web pages. Among other features, the language supports class persistent additions, verbal communication, first class types and the definition of object models in XML. Class persistent additions are an elegant solution to the problem of the stateless condition of the HTTP protocol and also it reduces i... View full abstract»

    Monolingual text-to-text generation is an emerging research area in natural language processing. One reason for the interest in such generation systems is the possibility to automatically learn text-to-text generation strategies from aligned monolingual corpora. In this context, paraphrase detection can be seen as the task of aligning sentences that convey the same information but yet are written ... View full abstract»

    Adaptive Web-based educational systems are a continuously growing area of research. However, despite the relatively numerous approaches, adaptivity from the point of view of student learning styles is not properly addressed. We therefore plan to create a framework for devising and deploying university courses that will take into account not only student's knowledge level but also his/her cognitive... View full abstract»

  • Optical CDMA; Optical Parallel Interference Cancellation Using the Lowest Threshold Value

    Publication Year: 2007, Page(s): 10
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (212 KB) | HTML iconHTML

    This paper presents the study of a receiver device for the optical code division multiple access (OCDMA) called the optical parallel interference cancellation (Opt-PIC). The performance of OCDMA system is known to be easily influenced by the multiple access interference (MAI) caused by other simultaneous users. To overcome this problem, there is a strong demand for the design of new detection sche... View full abstract»

    This paper analyzes the behavior of the Least Mean Square (LMS) adaptive algorithm in the minimum mean-squared error (MMSE) single user adaptive receiver for the asynchronous direct sequence-code division multiple access (DS-CDMA) system. It is known that in this context the adaptive algorithm can be iterated several times during the same bit interval in order to achieve a faster convergence rate ... View full abstract»

    We are researching a Web integrated reference architecture based on the mediator-wrapper approach. From a conceptual modeling point of view, this mediator is an architectural component defined by a semantic unification model composed of two layers. The lower layer, the specific ontological network (SON), is tailored to a concise application domain. It networks as many specific ontologies (SOs) (UR... View full abstract»

    In this paper we present an approach to fault-tolerant stream processing. In contrast to previous techniques that handle node failures, our approach also tolerates network failures and network partitions. The approach is based on a principled trade-off between consistency and availability in the face of failure, that (1) ensures that all data on an input stream is processed within a specified time...

    Digital video broadcasting-terrestrial (DVB-T) is important occasion in these days. But HDTV broadcasting is not widely used in Europe in DVB-T nets due high bandwidth requirements. Several solutions of this problem are discussed in this paper. Scalable video coding is the first choice but not very useful. MPEG-4 AVC coding algorithm brings a lot of new features and better compression efficiency a... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (136 KB) | HTML iconHTML

    In this paper, we propose a distributed data storage framework that supports unrestricted offline access. The system does not explicitly distinguish between connected and disconnected states. Its design is based on a lock-free distributed framework that avoids update conflicts through file versioning. The feasibility of this framework is confirmed by a proof-of- concept implementation. We also dem... View full abstract»

    This paper discusses a theatrical performance in a 3D collaborative virtual environment (3D CVE). Place in a performative 3D CVE is contingent on immersion and presence generated by social interaction. It discusses the production of an online performance of Plato's Allegory of the Cave involving students from three different continents. It was found that theatrical activities in a 3D CVE share som... View full abstract»

    The traditional map-matching algorithms mainly use two methods: the incremental method and the global method. Both of them have advantages and disadvantages of themselves: while the global map-matching algorithm produces better matching results, the incremental algorithm produces results of lower quality faster. All things considering the two traditional algorithms, this paper proposes a heuristic... View full abstract»
