It is a valuable study for Location-based Social Network (LBSN) make a moreaccurate Points-of-Interest (POI) recommendation since that can improve users'experiences. There have been many methods of POIs recommendation that consider context, personal preference pattern, and/or matrix factorization. However, the continuouscontexts have not been thoroughly considered in these methods. This paper first...
This paper explores what constitutes a trustworthy message in the context of e-learning. We did this by asking students to produce messages that they believed people like themselves would trust and then analyzed the data they produced. Coming from a user experience (UX) perspective, our interest is in improving the design of e-learning systems. We found that students reinforced and reiterated several...
Technical Causes Analysis (P.TCA) is a method for identifying technical causes of sub-optimum speech transmission quality. Originally created as an expert procedure for the annotation of speech samples, its applicability to naïve listener was also studied. Due to the low agreement of naïve listener annotations, it was suggested that detailed training methods are necessary to lift naïve annotations...
Smart cities and smart homes are booming fields of development of pervasive systems. With the high stakes these systems have to manage, and their sheer complexity, anomalies have to be considered. In these complex systems are many connected components with computing capacities. They can manage anomalies, even if partially, and can act as some kind of expert systems. These expert systems can be relied...
Developing countries are faced with varied challenges that include among others poverty, poor infrastructure, poor infusion and use of Information Technology (IT), poor education facilities and lack of experienced and skilled personnel. Education institutions especially those of higher learning are equally affected by these constraints. Bridging these gaps, education institutions in developing countries...
It is widely considered that relational capital serves as an important factor to foster collaboration in supply chain context. However, current knowledge on relational capital mechanisms which affects firm performance remains unclear. According to resource-based view, this article proposes a model to examine how relational capital affect firm performance through enhancing supply chain agility. In...
We consider several reliability problems that arise when allocating applications to processing resources in a Cloud computing platform. More specifically, we assume on the one hand that each computing resource is associated to a capacity constraint and to a probability of failure. On the other hand, we assume that each service runs as a set of independent instances of identical Virtual Machines, and...
How can an agent bootstrap up from a low-level representation to autonomously learn high-level states and actions using only domain-general knowledge? In this paper, we assume that the learning agent has a set of continuous variables describing the environment. There exist methods for learning models of the environment, and there also exist methods for planning. However, for autonomous learning, these...
According to group research, group members often fail to consider critical unique information in a group decision-making setting because of their motivated information-processing behavior. Given the complexity of experimental designs to investigate the problem, agent-based modeling can provide hypotheses that can work as theoretical guidance for future research. The purpose of this paper is to identify...
We investigate the reduction of atomic broadcast to consensus in systems with Byzantine faults. Among the several definitions of Byzantine consensus that differ only by their validity property, we identify those equivalent to atomic broadcast. Finally, we give the first deterministic atomic broadcast reduction with a constant time complexity with respect to consensus.
The software capability maturity model (SW-CMM) provides software organizations with guidance to how to gain control of their processes for developing and maintaining software and how to evolve toward a culture of software engineering and management excellence. Prof. J.N.Warfield has tried to identify and name each distinctive origin of one or more behaviorally related symptoms. Mindbugs (cognitive...
