Knowledge is the most important strategic tool for improving and maintaining organizational performance. Knowledge has become the essential part of every successful organization. This makes the organizations to put more effort in managing knowledge in a new systematic and effective way to accomplish it goals. Organization must be able to identify the need for introducing technology and process to contribute in facilitating knowledge sharing within the organization. This paper explains how influence and effective knowledge sharing is on educating and motivating the employees toward the organizational goals, the paper further explain the impact on knowledge sharing on organizational knowledge management as part of knowledge management to increase the level of employee knowledge and performance in the organization.

The critical path of a composite Web application operating in volatile environments, i.e., the execution path in the service composition with the maximum execution time, should be prioritised in cost-effective monitoring as it determines the response time of the Web application. In volatile operating environments, the critical path of a Web application is probabilistic. As such, it is important to estimate the criticalities of the execution paths, i.e., the probabilities that they are critical, to decide which parts of the system to monitor. We propose a novel approach to the identification of Probabilistic Critical Path for Service-based Web Applications (PCP-SWA), which calculates the criticalities of different execution paths in the context of service composition. We evaluate PCP-SWA experimentally using an example Web application. Compared to random monitoring, PCP-SWA based monitoring is 55.67% more cost-effective on average.

The paper presents a case report of the therapy by neurofeedback training of a chronic female schizophrenia outpatient. The purpose of the neurofeedback training was to enhance cognition, memory and behavioral performance. We used an intensive approach. All the training sessions were performed during 4 consecutive days. The results showed that the patient learnt to increase individual alpha amplitude and simultaneously decrease beta2 (20-30 Hz) amplitude at P4 site during active state over sessions. The individual alpha increased 74.73% and beta2 decreased 13.73%. The short term memory was enhanced after training. Her mood had positive change and her speech was much clearer than before. She started to associate the meaning of her life and illness. These results support that neurofeedback is not only a feasible therapy for schizophrenia but also positive results could be obtained using a much more intensive training sessions than the one reported in the literature. © 2012 IEEE.

Smart Mobile Devices (SMD) are there for many years but using them as learning tools started to emerge as new research area. The trend to merge collaborative learning methodology by using mobile devices in informal context is important for implementation of Learner Centric Learning (LCL). Survey and numerous studies show that more than 95% of students in colleges are users of these smart mobile devices in developed world. Developing counties are also catching up and we can see this percentage is almost same in university level in these countries. Students are using SMDs for learning in some form. Higher education Institutions also try to embark their E-learning to Mobile learning (ML). The aim of this paper is to do propose operational framework for designing Mobile Collaborative Informal learning activities using SMDs. Show results of experimental and case study done to study the Mobile Collaborative Informal learning using Activity Theory (AT). Core Components of framework are Mobile Learning Activities/Objects, Wireless/Mobile Smart devices, Collaborative knowledge and Collaborative learning. The research mention here is its infancy stage. © 2012, International Federation of Engineering Education Societies (IFEES). All rights reserved.

The service-oriented paradigm offers support for engineering service-based systems (SBSs) based on service compositions. The selection of services with the aim to fulfil the quality constraints for SBSs and to achieve the optimisation goals is a critical and challenging issue. In particular, when the quality-of-service (QoS) constraints for a SBS are severe, it is often difficult to find an optimal solution for the SBS. Exploiting the competition among service providers can help SBS developers obtain favourable QoS offers for the component services of SBSs and increase the possibility of finding optimal solutions for the SBSs. In this paper, we present a novel joint optimisation and negotiation approach named Iterative Negotiation for Service Composition (INSC) that supports effective and efficient QoS-aware service selection for SBSs. We evaluate INSC experimentally using example SBSs that are synthetically generated based on a real-world Web service dataset. The experimental results show that INSC can significantly and efficiently increase the possibility of finding optimal solutions in severe service composition scenarios. © 2012 IEEE.

With the rapid growth of wireless technologies and increasing number of mobile digital devices, mobility has been an important element on the Internet. NEMO Basic Support, designed by the Internet Engineering Task Force (IETF) to provide network mobility, is not efficient to offer low latency handoff in the case of nested mobile networks because it produces a long transfer delay and excessively large packet sizes due to non-optimal routes and multiple encapsulations. This paper presents a route optimization scenario for nested mobile network using hierarchical structure with Binding Update Tree (BUT). This scheme should reduce packet overhead, handoff latency, packet transmission delay, and achieve optimal routing. © 2012 IEEE.

Providing that licensed or Primary Users (PUs) are oblivious to the presence of unlicensed or Secondary Users (SUs), Cognitive Radio (CR) enables the SUs to use underutilized licensed spectrum (or white spaces) opportunistically and temporarily. A centralized CR system is an architectural model for a wide range of applications for example wireless medical telemetry service and medical implant communications service. As an enabling technology for white space exploitation, context awareness and intelligence (or cognition cycle, CC) remains the key characteristics of CR for using the underutilized licensed spectrum in an efficient manner. In this paper, we provide investigation into the application of a stateful Reinforcement Learning (RL) approach, to realize the conceptual CC in centralized static and mobile networks in the presence of many PUs. We investigate the use of RL with respect to Dynamic Channel Selection (DCS) that helps the SU Base Station (BS) to select channels adaptively for data transmission between different SU hosts. The purpose is to enhance the Quality of Service (QoS), particularly to maximise throughput and reduce delay by means of minimizing the number of channel switches. Simulation results reveal that RL achieves good performance and that the learning and exploration characteristics should converge to a low value to optimise performance.

Globally mathematics is a challenging subject. However, some parties wanted mathematics to be learnt using IT in a Diploma Information technology program in UTHM Johor for example. The objective of this paper is to prove whether mathematics IT used in a road traffic engineering case study could help the students’ understanding. Methodology used was quantitative as data on traffic flow was collected. There is a 0.58 Pearson correlation between the speed of cars with fatal accident cases and the marks from Mathematics final semester paper had improved besides the overall improvement to safer road traffic around Parit Raja vicinity.

Software system has become integral use in our daily life. The study focus is directed for future software requirement and how these requirements differ from traditional approach to cater future computing. The software requirements play a critical and important aspect that refers for developing software systems. The paper has identified five classifications of interaction which considered important in software requirement to reflect evolution in software environment. Subsequently, in understanding the classification of interaction take in a new formulation to produce the software requirements for future software systems by taking into account crucial software requirement attributes such maintainability, reliability, adaptability and usability etc. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.
