IEEE International Conference on e-Business Engineering (ICEBE)

We present a service resource selection and scheduling approach capable of maximizing the resource utilization rate (RUT) and the requirement satisfaction degree (RSD) by bundling multiple customer requirements (CRs). In traditional approaches, each CR is optimally satisfied by independently selecting a set of candidate service resources. This possibly leads to a low RUT and low RSD. In our approach, multiple CRs raised within a certain time period are bundled and a virtual service resource (VSR) is constructed to satisfy these requirements simultaneously by making full use of the sharing nature of resources. Specifically, each CR is first decomposed into a set of atomic requirements, which are then re-aggregated according to their requested resources. For four types of service-resource sharing patterns, we present the corresponding greedy algorithms that construct the VSR and its scheduling. The goals of our methods are (1) maximizing the satisfaction degree of CRs and (2) maximizing the RUT of service resources. The effectiveness of our approach is demonstrated in an experiment for a typical scenario of ocean transportation service.

We present a value-driven approach capable of determining the global optimization objective of service composition to satisfy high-level value expectations. In traditional service composition methods, global and local QoS requirements and constraints are directly raised by customers, then a set of service components (web services) are selected to achieve the optimized QoS. Yet in practice, there is no mechanism helping customers accurately and comprehensively determine their QoS desires. In our approach, a customer's initial expectations of high-level global values are first put forward, and then five types of dependencies between service values are analyzed. Because values are realized under the facilitation of specific service components, value expectations and value dependencies are transformed into the objective and constraints of service selection and composition, respectively. Another feature of our approach is that, besides web services, other generalized service components such as human activity and physical resources are considered as potential components for fulfilling value expectations. The effectiveness of our approach is demonstrated in a case study of ocean transportation service (OTS).

This paper presents a service resource management system. It is oriented to both single and integrated service resources and manages every stage of service resource lifecycle efficiently which includes registering, publication, usage, destruction processes. To satisfy different specific service area, the developer only needs to configure the template provided by the service resource management system, which will greatly shorten the development cycle and increase the development efficiency. The paper is organized as follows: firstly, the paper presents the concept of the service resources, and introduces how to classify and depict them. Secondly, using UML use case analyzes the requirement of the service resource management. Thirdly, the service resource management system design is put forward. At the end, it introduces how to apply the system to a specific service area briefly.

Service modeling is a critical step in describing customer requirements and designing service systems. The quality of service models determines the quality of service systems to a great extent. To analyze the service models in a way that would show deficiencies in delivering service values, we propose the idea of "value annotation" by which expected values are labeled on the functional elements of service models, and their implementation degrees are connected with QoS of these functional elements. Value annotation's elementary principles, process, and model forms are presented. Then, the preliminary principles of value annotation-based service model analysis are briefly introduced. To complement the above discussion, a small case study from ocean transportation service is applied for demonstration.

A dream of humanoid robot researchers is to develop a complete "human-like" (whatever that means) artificial agent both in terms of body and brain. We now have seen an increasing number of humanoid robots (such as Honda's ASIMO, Aldebaran's Nao and many others). These, however, display only a limited number of cognitive skills in terms of perception, learning and decision-making. On the other hand, brain research has begun to produce computational models such as LIDA. In this paper, we propose an intermediate approach for body-brain integration in a form of a scenario-based distributed system. Busy hospital Emergency Departments (ED) are concerned with shortening the waiting times of patients, with relieving overburdened triage team physicians, nurses and medics, and with reducing the number of mistakes. Here we propose a system of cognitive robots and a supervisor, dubbed the TriageBot System that would gather both logistical and medical information, as well as take diagnostic measurements, from an incoming patient for later use by the triage team. TriageBot would also give tentative, possible diagnoses to the triage nurse, along with recommendations for non-physician care Some of the robots in the TriageBot System would be humanoid in form, but it is not necessary that all of them take this form. Advances in humanoid robotic design, in sensor technology, and in cognitive control architectures make such a system feasible, at least in principle. ©2010 IEEE.

This paper represents a technique, applying user action patterns in order to distinguish between users and identify them. In this method, users' actions sequences are mapped to numerical sequences and each user's profile is generated using autocorrelation values. Next, cross-correlation is used to compare user profiles with a test data. To evaluate our proposed method, a dataset known as Greenberg's dataset is used. The presented approach is succeeded to detect the correct user with as high as 82.3% accuracy over a set of 52 users. In comparison to the existing methods based on Hidden Markov Model or Neural Networks, our method needs less computation time and space. In addition, it has the ability of getting updated iteratively which is a main factor to facilitate transferability. © 2010 IFIP.

IEEE International Conference on Cluster computing

In cluster file systems, the metadata management is critical to the whole system. Past researches mainly focus on journaling which alone is not enough to provide high-available metadata service. Some others try to use replication, but the extra latency accompanied is a main problem. To guarantee both availability and efficiency, we propose a mechanism for building highly available metadata servers based on replication, which integrates Paxos algorithm effectively into metadata service. The Packed Multi-Paxos is proposed to reduce the latency brought by replication, which is self-adaptive and can make the replication to achieve high throughput under heavy client load and low latency under light client load. By designing efficient architecture and coordination mechanism, all replica server nodes simultaneously provide metadata read-access service. This high-available mechanism could decrease the impact of server failures and there is no interruption of service. The performance results show that the latency caused by replication and redundancy is well under control, and the performance of metadata read operation gains improvement.
