The integration temperature difference ΔTi considers the heat transfer routes, linking the heat transfer process with the thermodynamic behavior of heat exchangers. The first and second non-dimensional integration temperature differences are defined as ΔTi,h∗=ΔTi/Th,i and ΔTi,s∗=ΔTi/(Th,i-T0) respectively, where Th,i is the heat source temperature and T0 is the environment temperature.

In Pub/Sub systems, channel-based approaches to routing the subscriptions and events have many advantages such as fewer routing messages, lower costs for subscription management, etc. But a potential issue embedded in this kind of approach, i.e. loadings on different event brokers are apt to unbalancing, is ignored more or less. In this paper, we design a load balancing mechanism and integrate it...
In a Pub/Sub system, the procedure of distributed event detection can be divided into two interacting phases: the subscription matching and the subscription/event routing. Also, the performance of the system is greatly influenced by these two parts. Adopting a reuse strategy in matching and routing can reduce matching workload and network traffic. However, few of the existing researches provide a...
Pub/Sub systems can facilitate monitoring and managing objects for RFID applications. To fully support RFID applications, Pub/Sub systems should provide the means of subscribing RFID tags and the corresponding efficient matching algorithm. This paper provides the management mechanism and matching algorithm for primitive subscriptions whose specification permits to subscribe RFID codes. Our approach...
In a Pub/Sub system, if the clients are permitted to move randomly, their mobility will cause their access brokers to be changed, which has brought in problems in dissemination of subscriptions and distribution of matching results. We claim that channelization-based routing algorithms can be applied to the Pub/Sub systems which support wireless clients. In this paper, we discuss the related issues...
