    Attempt has been made to design and develop a complete adoptive Multi Agent System pertaining to merchant brokering stage of Customer Buying Behaviour Model with the intent of appropriate framework. Intelligent agents are autonomous entity which observe and act upon an environment. In general, they are software robots and vitally used in variety of e-Business applications. This paper focuses on the discussions on electronic markets and the adoptive role, which agents can play in information transformation for automating e-market transactions. It is proposed to develop a framework for agent-based electronic markets for buyers and sellers totally with the assistance of software agents.Agent Oriented e-Business, Agent Oriented e-Markets, Buyer/Seller Agents, Java, Multi Agent Systems

    In this paper, we propose a united architecture for the creation of life-long user profiles. Our architecture combines different steps required for a user prole, including feature extraction and representation, reasoning, recommendation and presentation. We discuss various issues that arise in the context of life-long profiling

    An Energy Aware and Secure MAC Protocol for Tackling Denial of Sleep Attacks in Wireless Sensor Networks

    Get PDF
    Wireless sensor networks which form part of the core for the Internet of Things consist of resource constrained sensors that are usually powered by batteries. Therefore, careful energy awareness is essential when working with these devices. Indeed,the introduction of security techniques such as authentication and encryption, to ensure confidentiality and integrity of data, can place higher energy load on the sensors. However, the absence of security protection c ould give room for energy drain attacks such as denial of sleep attacks which have a higher negative impact on the life span ( of the sensors than the presence of security features. This thesis, therefore, focuses on tackling denial of sleep attacks from two perspectives A security perspective and an energy efficiency perspective. The security perspective involves evaluating and ranking a number of security based techniques to curbing denial of sleep attacks. The energy efficiency perspective, on the other hand, involves exploring duty cycling and simulating three Media Access Control ( protocols Sensor MAC, Timeout MAC andTunableMAC under different network sizes and measuring different parameters such as the Received Signal Strength RSSI) and Link Quality Indicator ( Transmit power, throughput and energy efficiency Duty cycling happens to be one of the major techniques for conserving energy in wireless sensor networks and this research aims to answer questions with regards to the effect of duty cycles on the energy efficiency as well as the throughput of three duty cycle protocols Sensor MAC ( Timeout MAC ( and TunableMAC in addition to creating a novel MAC protocol that is also more resilient to denial of sleep a ttacks than existing protocols. The main contributions to knowledge from this thesis are the developed framework used for evaluation of existing denial of sleep attack solutions and the algorithms which fuel the other contribution to knowledge a newly developed protocol tested on the Castalia Simulator on the OMNET++ platform. The new protocol has been compared with existing protocols and has been found to have significant improvement in energy efficiency and also better resilience to denial of sleep at tacks Part of this research has been published Two conference publications in IEEE Explore and one workshop paper

    Tune in to your emotions: a robust personalized affective music player

    Get PDF
    The emotional power of music is exploited in a personalized affective music player (AMP) that selects music for mood enhancement. A biosignal approach is used to measure listeners’ personal emotional reactions to their own music as input for affective user models. Regression and kernel density estimation are applied to model the physiological changes the music elicits. Using these models, personalized music selections based on an affective goal state can be made. The AMP was validated in real-world trials over the course of several weeks. Results show that our models can cope with noisy situations and handle large inter-individual differences in the music domain. The AMP augments music listening where its techniques enable automated affect guidance. Our approach provides valuable insights for affective computing and user modeling, for which the AMP is a suitable carrier application

    Good Helping Relationships in Child Welfare: Co-authored Stories of Success (SUMMARY REPORT)

    Get PDF
    This project involved multiple, in-depth interviews with six worker-client dyads from child welfare. The dyads were selected on the basis of workers and clients agreeing that they had worked through some degree of negative interpersonal process toward the achievement of a good working relationship. For each dyad, two individual interviews with the worker and the client were followed by a joint interview. These interviews produced stories that described from workers\u27 and clients\u27 perspectives how the relationship developed over time, how difficulties were dealt with, and what impact the relationship had on the participants. Although these stories were written by the researchers, they were co-authored by workers and clients in the sense that the participants reviewed drafts of their stories, made suggestions for revisions, and agreed that the final product fairly represented their experience. Across story analyses yielded common themes with regard to worker and client contributions to the development of a good relationship, the qualities of a good relationship, and central issues and turning points in relationship development and client change. The results paint a picture of a good working relationship that is deeply human, integrates personal and professional elements, and takes time and effort to develop. Findings also provide insights about how the challenges of developing good relationships in child welfare, and in any helping endeavour, can be dealt with productively

    A Case for Developing Spiritual Intelligence in Leaders through Equine Facilitated Learning

    Get PDF
    Unpredictable circumstances, growing stresses in an ever-increasing global market, and ubiquitous ennui have left organizations and today’s leaders in government, industry, and academia without the necessary tools to transition to change in a principled manner. The authors explain that the development and maintenance of genuine leadership skills — adaptive to the dictates of the modern world — must be borne from one’s inner self, a retreat to spirituality. One available method of achieving this is through Equine Facilitated Experiential Learning (EFEL), a technique whereby leaders develop critical management skills by working with horses

    Why Do Relationships Matter to Project Managers? 3 Elements to Integrate into Every Project Manager Tool-Kit

    Get PDF
    Abstract Emotional intelligence is one of the essential attributes of success in the workplace and life. It is a skill that can be learned and developed. The ability to manage emotions is also a part of it. Emotional intelligence can be taught, practiced, and mastered by anyone who wants to become a better manager. It is not just about managing your emotions but being able to manage them effectively if you want to become a better leader. One of the hallmarks of effective project leadership is building constructive relationships. Relationship building is essential because project managers do not typically have authority over the team. If projects are to be successfully completed, the project manager must rely on working with others – this requires relationships. The more complex the project, the more people want your attention. It is impossible to do justice to them all, so it is time to prioritize the list to keep your most important working relationships manageable and growing
