1. Optimization of Service Quality for Marathon Events: Model Construction and Efficiency Measurement.

Author

LIANG Yuan, LI Pei, WANG Zhaohong, LI Jinglyu, and LI Shuwang

Abstract

This study is based on the SERVQUAL maturity scale and takes the service of China's golden standard marathon events as an example. By constructing an IPA model,the empirical analysis is conducted using "importance" and "satisfaction" as coordinate units to evaluate the service quality and efficiency for marathon events. It is found that in terms of dimension structures, the respondents have a positive attitude towards the dimensions of " responsiveness" and "assurance" for event services; but the service quality level of marathon events is relatively low in the dimension of "empathy". In terms of indicator setting, the stability of the service system stands out as the bright spot and the core competitiveness of marathon event services. However, there are still some issues such as inefficient allocation and insufficient professionalism of service personnel. Based on this, it is proposed that the perceived experience value of participants should be enhanced from the improvement of "empathy"; the events should attract the widespread participation of social capital from the enhancement of "tangibility"; the establishment and improvement of personnel incentive mechanisms should be achieved from the deepening of "reliability"; and differentiated service plans should be established from the boost of "responsiveness" so as to provide a theoretical basis and practical references for the optimization of the service quality of marathon events.

Abstract

The article considers importance of formation of the acting system of personnel management, since personnel determines the competitive potential and competitive advantages of an organisation. It develops a cognitive model of a business situation, which helps to present the process of attraction and reproduction of temporary personnel at enterprises, which deal with organisation of large-scale events, and influence of the factors upon each other. It builds a conceptual model of a business situation of attraction and reproduction of temporary personnel of the event service and, on its basis, offers a model of decision making with the use of elements of fuzzy logic on selection of a specialist for a specific position. It allocates main characteristics of employees, which are taken into account when forming decisions regarding taking on a candidate.

Abstract

Using an indirect event service instead of other traditional communication models has an advantage of decreasing the coupling of applications in a distributed environment and removing the need for many static dependencies. In this paper, we design and implement the secure event service for providing a secure ubiquitous computing environment. The Secure Event Service implemented in this paper enables users to perform content-based event retrieval, and supports only eligible event consumer and event producer to publish and receive events through the secure event service. The SPKI/SDSI certificate is used for supporting authentication and authorization in the secure event service. In order to provide content-based event retrieval, an asynchronous communication between event producers and consumers, and a disconnectedness support for mobile devices, we modify and expand the JavaSpace package.

Abstract

Multimedia delivery in mobile multiaccess network environments has emerged as a key area within the future Internet research domain. When network heterogeneity is coupled with the proliferation of multiaccess capabilities in mobile handheld devices, one can expect many new avenues for developing novel services and applications. New mechanisms for audio/video delivery over multiaccess networks will define the next generation of major distribution technologies, but will require significantly more information to operate according to their best potential. In this paper we present and evaluate a distributed information service, which can enhance media delivery over such multiaccess networks. We describe the proposed information service, which is built upon the new distributed control and management framework (DCMF) and the mobility management triggering functionality (TRG). We use a testbed which includes 3G/HSPA, WLAN and WiMAX network accesses to evaluate our proposed architecture and present results that demonstrate its value in enhancing video delivery and minimizing service disruption in an involved scenario.

Abstract

Event services based on publish–subscribe architectures are well-established components of distributed computing applications. Recently, an event service has been proposed as part of the common component architecture (CCA) for high-performance computing (HPC) applications. In this paper we describe our implementation, experimental evaluation, and initial experience with a high-performance CCA event service that exploits efficient communications mechanisms commonly used on HPC platforms. We describe the CCA event service model and briefly discuss the possible implementation strategies of the model. We then present the design and implementation of the event service using the aggregate remote memory copy interface as an underlying communication layer for this mechanism. Two alternative implementations are presented and evaluated on a Cray XD-1 platform. The performance results demonstrate that event delivery latencies are low and that the event service is able to achieve high-throughput levels. Finally, we describe the use of the event service in an application for high-speed processing of data from a mass spectrometer and conclude by discussing some possible extensions to the event service for other HPC applications.

Abstract

This paper presents the concept of a Web-based knowledge network. A knowledge model is first described and then the overall architectural framework of the knowledge network is discussed. The implemented prototype system allows providers of information resources and/or application system services to publish not only their data resources and/or services on Web pages, but also their knowledge expressed in forms of events, rules, and triggers associated with the contents and operations of these pages. Internet users can access these Web pages, subscribe to some published events in a registration process, and provide values for event filters and customizable rules. The subscribers can also specify additional triggers and rules of their own that are to be processed on the subscribers'' sites. At run-time, when an event is posted by a provider (human or automated application system), event filters are processed, the relevant subscribers are notified, and both the provider and subscribers'' triggers and rules are processed on their respective sites. The architectural framework allows both providers and subscribers of information resources and services to contribute their knowledge to the Internet, thus forming a Web-based knowledge network instead of the present data/information network. The knowledge network is constructed by a number of replicable software components, which can be installed at various network sites. They, together with the existing Web servers, form the knowledge Web servers. [Copyright &y& Elsevier]

29. Event Detection Services Using Data Service Middleware in Distributed Sensor Networks.

Author

Li, Shuoqi, Lin, Ying, Son, Sang, Stankovic, John, and Wei, Yuan

Abstract

This paper presents the real-time event detection service using Data Service Middleware (DSWare). DSWare provides data-centric and group-based services for sensor networks. The real-time event service handles unreliability of individual sensor reports, correlation among different sensor observations, and inherent real-time characteristics of events. The event service supports confidence functions which are designed based on data semantics, including relative importance of sub-events and historical patterns. When the failure rate is high, the event service enables partial detection of critical events to be reported in a timely manner. It can also be applied to differentiate between the occurrences of events and false alarms. [ABSTRACT FROM AUTHOR]

Abstract

Asynchronous Data Exchange (ADE) is useful in Electronic Data Interchange (EDI). It needs a well-defined mechanism to support data buffing, dispatching, and filtering. ADE is more flexible, extensible and scalable than the synchronous one. CORBA Event Service, announced by OMG, offers an easy-to-use, abstract and generic communication mechanism, while providing message delivering, dispatching and buffering by way of introducing the concept of event channels. However, it lacks some practical data exchange functions.This paper proposes the design and implementation of a system named CODEX (stand for Content-Oriented Data EXchange system), which combines the XML features and the functionality of CORBA (which stands for Common Object Request Broker Architecture) Event Service. The CODEX system equips functions of primitive data type checking, message classification, content filtering and source/destination screening. Application developers can focus more on business functions, instead of caring about the detail of data exchange. The concept and architecture of the content-oriented data exchange, provided by CODEX, can be applied to other practical computing fields in the large-scale, loosely coupled distributed computing environments.

Abstract

To improve the real-time and fault-tolerant performance of data transmission in sensor-based distributed power monitoring system, the principle of event service in common object request broker architecture was analyzed, and the "subscribe/publish" mechanism was realized by improving and extending event service in push model in order to reinforce real-time performance. And a semi-active copy method of fault-tolerant was proposed under push model. On this basis, the model of real-time and fault-tolerance middleware in the power monitoring system was designed and realized with these methods. This model was used in the network communication layers of multiple power monitoring systems, and the results shows that the model is safe and reliable with real-time response.

38. Designing and analyzing an event service for sensor networks

Author

Gujrati, Sumeet. and Gujrati, Sumeet.

Abstract

This work is motivated by the OMG's CORBA Event Service Specification. CORBA is the acronym for Common Object Request Broker Architecture. In this research, we implemented and analyzed an event service using a model similar to the OMG model for sensor networks applications which are written in nesC programming language, an extension of C programming language. This implementation has been tested on a test bed created using Crossbow's TelosB motes and Crossbow's Stargate Netbridge modules as gateways. Event service interface implementations, which reside on the motes, are written in nesC. The data routing part, which is done through Stargate Netbridges, is written in the C language. This document contains experimental results obtained by deploying and running the implementation on the test bed.

Abstract

As embedded systems increase in complexity and begin to participate in distributed systems, the need for middleware in the building of such systems becomes imperative. However, the use of middleware that fully implements such standards can impose a significant increase in footprint for an application, making it unsuitable for use in embedded systems. We consider the use of a standard CORBA event channel in a setting where distribution and inter-language support are unnecessary. We report our experience in applying aspects to abstract the transport layer (CORBA) of the event channel into a selectable feature. Thus, enabling or disabling CORBA for a specific application can be decided at build-time, by merely selecting CORBA as a feature. We describe the patterns used to achieve this abstraction and present footprint and throughput results showing the effect of CORBA on automatically derived subsets of the event channel., Prepared in cooperation with Washington Univ, Dept. of Computer Science and Engineering, St. Louis, MO 63130.

Abstract

We describe Peer-to-Peer Grids built around Integration of technologies from the peer-to-peer and Grid fields. We focus on the role of Web services linked by a powerful event service using uniform XML interfaces and application level routing. We describe how a rich synchronous and asynchronous collaboration environment can support virtual communities built on top of such infrastructure. Universal access mechanisms are discussed.

Abstract

Colloque avec actes et comité de lecture. internationale.; International audience; The need for interoperability among the rapidly proliferating number of hardwares and softwares led to the definition of CORBA (Common Object Request Broker Architecture). This architecture offers a good interoperability and communication support and the use of such architecture for distributed metacomputing applications seems interesting and promising. However, its implementation is difficult because of protocol diversity and communication modes used by parallel applications. To cure this problem, we develop a message passing library in CORBA environment called MPC (Message Passing in CORBA). In this paper, we quickly present the basic concepts of this library and its broadcast protocol based on the CORBA event service.
