With the emergence of the World Wide Web, analyzing and improving Web communication has become essential to adapt the Web content to the visitors’ expectations. Web communication analysis is traditionally performed by Web analytics software, which produce long lists of page-based audience metrics. These results suffer from page synonymy, page polysemy, page temporality, and page volatility. In addition, the metrics contain little semantics and are too detailed to be exploited by organization managers and chief editors, who need summarized and conceptual information to take high-level decisions. To obtain such metrics, we propose to classify the Web site pages into categories representing the Web site topics and to aggregate the page hits accordingly. In this paper, we show how to compute and visualize these metrics using OLAP tools. To solve the page-temporality issue, we propose to classify the versions of the pages using automatic classifiers.

This paper outlines the applicative environment and sketches the technical details of an FM subcarrier technology called multipurpose radio communication channel (MPRC). This technology delivers data at maximum data rate of around 40 kbs using a proprietary codec algorithm, subsidiary communication channel (SCC). As a result it is possible to obtain video transmission in QCIF format at roughly 8/12 fps using 35 kHz of the 100 kHz available for a commercial FM radio station in Europe. In this way, it is possible to transmit video on FM radio together with the usual radio broadcasting. SCC is briefly described in its main characteristics

As online communication is more and more integrated in everyday life to support and maintain existing social ties, this study examined the factors associated with preference of face to face, phone or online conversations. A contextual framework that emphasizes the role of relationship origin, relationship intensity and content of communication on communication channel choice among adolescents was empirically tested. Based on a nationwide survey in Israel, it was found that communication content, relationship origin ...

Investment systems are studied using a framework that emphasize their profiles (the cumulative probability distribution on all the possible percentage gains of trades) and their log return functions (the expected average return per trade in logarithmic scale as a function of the investment size in terms of the percentage of the available capital). The efficiency index for an investment system, defined as the maximum of the log return function, is proposed as a measure to compare investment systems for their intrinsic merit. This efficiency index can be viewed as a generalization of Shannon’s information rate for a communication channel. Applications are illustrated. © 2006 Elsevier Inc. All rights reserved.

We present evidence for the importance of low-level phenomena in dialogue interaction and use this to motivate a multi-layered approach to dialogue processing. We describe an architecture that separates content-level communicative processes from interaction-level phenomena (such as feedback, grounding, turn-management), and provide details of specific implementations of a number of such phenomena.

The Distributed Computing Software project at Oxford University is using formal specification techniques to explore the design of services in a distributed operating system. Our goal is to construct and publish the specification of a loosely-coupled distributed operating system consisting of a number of autonomous services. Some design principles have been proposed from consideration of conventional business practice. Several services have already been designed and implemented according to these principles.

The sense of touch is an effective, but underutilized, human communication channel. In this paper we describe our research efforts towards optimizing a minimal tactile array for personal navigation and route guidance. There are several aspects to this problem. From an information transfer viewpoint, the question of tactor array size, dimension, location and display symbology requires careful consideration. Effective tactile display symbology involves providing information in an intuitive manner without adding to the cognitive loading of the user. Tactile information may be presented through spatial, temporal and signal variables. We have recently developed new wearable tactors that offer wide sensory capabilities to provide different “feeling” stimuli. These actuators are non-linear in that the salient characteristics for perception are linked to a complex drive stimulus. We have therefore developed a tactor activation design approach termed “TActions” (Tactile Actions) where patterns or sequence of individual tactile stimuli, each of which has its own characteristics and properties, are used to create tactile display symbology that a user can naturally associate with a particular function. These components provide display design frame work which we have used to demonstrate orientation and navigation.

Quantum key distribution algorithms use a quantum communication channel with quantum information and a classical communication channel for binary information. The classical channel, in all algorithms to date, was required to be authenticated. Moreover, Lomo- naco [8] claimed that authentication is not possible using only quantum means. This paper reverses this claim. We design an algorithm for quantum key distribution

When the mechanisms of fading channels were first modeled in the 1950s and 1960s, the ideas were primarily applied to over-the-horizon communications covering a wide range of frequency bands. The 3-30 MHz high-frequency (HF) band is used for ionospheric communications, and the 300 MHz-3 GHz ultra-high-frequency (UHF) and 3-30 GHz super-high-frequency (SHF) bands are used for tropospheric scatter. Although the fading effects in a mobile radio system are somewhat different than those in ionospheric and tropospheric channels, the early models are still quite useful to help characterize fading effects in mobile digital communication systems. This tutorial addresses Rayleigh fading primarily in the UHF band. That affects mobile systems such as cellular and personal communication systems (PCS). Part I of the tutorial itemizes the fundamental fading manifestations and types of degradation

Analysis of the pathways by which research outputs come to the attention of potential users, and of factors which influence uptake, requires selection of an appropriate analytical framework and set of indicators. The main factor influencing uptake by users, is the relevance to them of the research output itself. Relevance is not inherent in the research output, but a function of specific contextual factors. In addition the features of the research process and the ‘target’ have a bearing on uptake by intermediate users. Six analytical frameworks are briefly presented and compared. Models of the technology development process suggest questions about the nature and efficiency of linkages between the different elements of the process. Models of information processes focus on the fact that information is not simply passed on but is continually being transformed and adapted through communication. Models of the research management process suggest that the main determinant of relevance is the care and collaboration with which research goals are determined and research implementation is monitored and managed. Systems models allow us to move away from unilinear conceptions of technology development, and can deal more effectively with the diversity of information sources and channels available to potential users. This is also true of the multiple source of innovations and ‘farmer first’ models. Each framework has its uses and limitations: for any particular study, it is important to select one that is most suited to the type of research output and the particular issues under consideration. A wide range of socio-economic research methods have been used to explore promotion and uptake issues. Standard sample survey methods have limitations and alternatives are suggested. Publication, face-to-face interaction and electronic communication are the main pathways for promotion to fellow scientists. Long term relationships between collaborating institutions, and stability in research team composition, are factors in effective promotion at this level. Access to scientific publications in developing country research institutions is seen as a major constraint. Much is already known about the effectiveness of extension and communication methods among end users. There is undoubtedly a lot of untapped potential in the emerging communication technologies for low cost, effective access to agricultural information. The paper ends by suggesting a number of areas for future research on promotion and uptake.

LFSR based PN Sequence Generator technique is used for various cryptography applications and for designing encoder, decoder in different communication channel. It is more important to test and verify by implementing on any hardware for getting better efficient result. As FPGAs is used to implement any logical function for faster prototype development, it is necessary to implement the existing design of LFSR on FPGA to test and verify the simulated & synthesis result between different lengths. The total number of random state generated on LFSR depends on the feedback polynomial. As it is simple counter so it can count maximum of 2n-1 by using maximum feedback polynomial. Here in this paper we implemented 8, 16 and 32-bit LFSR on FPGA by using VHDL to study the performance and analysis the behavior of randomness. The analysis is conceded out to find number of gates, memory and speed requirement in FPGA as the number of bits is increased. The comparative study of 8, 16 and 32 bit LFSR on FPGA is shown here to understand the on chip verification. Also the simulation problem for long bit LFSR on FPGA is presented.

The demand for accelerated speed, anywhere, and any time connectivity has made wireless communication networks increasingly dense. This has resulted into intense research on how speed of data transfer, security of data, spectrum sharing, and storage of the big data realized can be improved in an efficient way. However the major challenge which has necessitated continuous research progress in the subject is the study of communication path loss and shadowing and how it can be eliminated or lessened to improve the channels involved. This paper will perform experiments on radio propagation models, ray tracing models and perform its simulations in Matlab, as well as provide a review of the various path loss models. The simulation results obtained indicated that when the receiver far away from the transmitter, the signal begins to be weaker and weaker until it is lost. However if the receiver will move away from a closer base station, and while the signal is weakening, it encounters another base station, the two base stations performs a handshake and the signal will start gaining strength.

The objective of this article is to point out factors that contribute to the dissociation between educational theory and practice, and to present the strategies for their reunification. The text deals with the devastating effect of this conceptual rift, which gives rise to an endless dilemma involving researchers, teachers, and educational managers. In such scenario, because of the lack of a communication channel between Science and current pedagogical practices, the results of this study reveal: a) the existence of feelings of threat to the credibility of Education as a profession; b) the possibility of scientists inadvertently outlining conceptual models distanced from the reality of the classrooms; and c) the risk that those responsible for public policies begin to defend educational practices that turn out to be ineffective in our days. Therefore, the article shows guidelines for the reunification of the concepts of educational theory and practice, emphasizing: a) the professional education of the teacher-researcher; b) the participation of the researcher in the school daily life; and c) the collaborative work between the academic researcher and the teacher in the classroom. Lastly, the work presents two North American educational programs that succeeded in associating academic research to school practice, using as their support a developmentalist model of work.

Internal Communication is the foundation of all organizations communication strategies because it involves not only the management and the staff alike but also on the effectiveness of the communication within an organization. Recent literature (Linjuan, 2014; Odine, 2015; Omilion-Hodges & Baker, 2014) described Internal Communication as an important tool to communicating within organizations. The purpose of this research is to investigate the root cause of the Internal Communication Barriers within (a Catholic Religious Organization) which examined three research questions to arrive at a result. The study critically observed the following research questions: 1) What is the root cause of the Internal Communication Barriers within the Organization? 2) How is the communication structures of the organization affecting the people? And lastly, 3) why are the leadership style and the management decisions of the organization affecting employee behaviour?
The research is motivated by two major reasons: a) to find the reasons behind the inadequate use of the communication structures that exist within the organization, and b) Communication Audit has never been carried out within the organization and pursuing this research means that it is the first ever to be carried out within the organization. The research methodology used in this study is the interview method (semi-structured interview, with the use of open-ended questions). An audiotape was used to record the findings from the research, and the data generated were analysed and transcribed using qualitative research and thematic analysis. The interview took place in the conference room of the organization and the population of interest were selected at random using a systematic random sampling technique. Six participants partook in the interview to cut across all the various psychological groups within the organization. The research participants were recruited from the Finance, Administrative and the Managerial Departments of the organization. The ethical concerns raised by the research was the confidentiality issue which formed the major problem of the research. The code of the research conduct observed in this study were respect, confidentiality, integrity and responsibility. The result of the Mini Communication Audit showed a great challenge for the organization's communication channels and the practical and theoretical implications of the outcome were discussed. The recommendation in the practice of the organization's communication structure was reviewed and future research projected.
