Abstract¿An important issue in the dissemination of time-varying web data such as sports scores and stock prices is the maintenance of temporal coherency. In the case of servers adhering to the HTTP protocol, clients need to frequently pull the data ...

Under dynamic and heterogenous environment, the need for adaptability and rapid response time to information service systems has become increasingly important. To cope with the continuously changing conditions of service provision and utilization, Faded ...

A 530 kG gate array with novel GTL I/O circuits has been developed using 0.5 /spl mu/m CMOS triple-metal-layer process technology. The I/O circuit of a push-pull output driver and a dynamic termination receiver can transmit 250 Mb/s data through a long ...

Peer-to-peer (P2P) file sharing has become increasingly popular, accounting for as much as 70% of Internet traffic by some estimates. Recently, we have been witnessing the emergence of a new class of popular P2P applications, namely, P2P audio and video ...

How to get a better balance between the push and pull of the event data is the common goal of the various data dissemination algorithms in Wireless Sensor Networks (WSNs). And the characteristics of the Any-type Query in WSNs is different from the All-type ...

The market and users' requirements have been rapidly changing and diversified. Under these heterogeneous and dynamic situations, not only the system structure itself, but also the accessible information services would be changed constantly. To cope with ...

This paper presented design concepts to improve stroke magnification and to retain high torsional frequencies for piezoelectrically actuated suspension. Flexural rotation is employed to enhance stroke magnification at the dimple point of a load beam. ...

With the development of network technology, image-based real-time monitoring system has become a hot topic in the area of industrial automation, but in the current real-time system, the large volume of data transmission and the frequent interaction between ...

Consider a network in which a collection of source nodes maintain and periodically update data objects for a collection of sink nodes, each of which periodically accesses the data originating from some specified subset of the source nodes. We consider ...

The rapid growth of information technology and the Internet give rise to an increasing demand for information services. A large number of service providers offer information services to diversified users on the Internet. Users' requirements are heterogeneous ...

We develop a framework for minimizing the communication overhead of monitoring global system parameters in IP networks and sensor networks. A global system predicate is defined as a conjunction of the local properties of different network elements. A ...

This paper investigates the possibility of applying hybrid push/pull production control strategies in a transmission overhaul shop. The shop currently uses MRP/push system. The high variability in process times and limited resources available make it ...

We consider a push pull queueing system with two servers and two types of jobs which are processed by the two servers in opposite order, with stochastic generally distributed processing times. This push pull system was introduced by Kopzon and Weiss, ...

In this paper, we present a novel hybrid push-pull algorithm which combines broadcasting of push data items, with dissemination upon request of pull items in asymmetric communication environments. These environments are made up only of one database server ...

P2P live streaming systems are developed in two major approaches: tree-push versus mesh-pull. The hybrid push-pull streaming, as an emerging and promising approach, offers a good tradeoff between traffic overhead and system throughput. In this paper, ...

In this paper, we argue that cache consistency mechanisms designed for stand-alone proxies do not scale to the large number of proxies in a content distribution network and are not flexible enough to allow consistency guarantees to be tailored to object ...

As the improvement of environmental consciousness of society, the economic value of automobiles’ reverse logistics comes out prominently. Strengthening the research on automobile reverse logistics plays an important role in the development of national ...

Web services are becoming increasingly complex as users become more experienced in their requests to access an ever growing collection of information on the Web. In this paper we review the state of the art in programmable HTTP proxies.We discuss and ...

In this paper, we present an unstructured peer-to-peer network called GridMedia for live media streaming employing a push-pull approach. Each node in GridMedia randomly selects its neighbors in the overlay and uses push-pull method to fetch data from ...
