The diagnosis-stage is always the bottleneck stage for the normal arriving patient flow and the referral patient flow influx in Outpatient Department (OD) in Chinese hospital. And the referral patient has high-priority than the normal arriving patient in general. How to minimize the referral patients mean waiting time and meanwhile keeping the normal patients queue stable? Around the goal a general...
A workflow net is a Petri net for modeling and analyzing a workflow. A process tree has been proposed as a representational bias of a workflow net and enabled us to grasp the structure of actions routing such as sequence, choice and parallel in the workflow net. The advantage of process trees enables us to grasp the structure of action routing such as sequence, choice, and parallel in a given workflow...
OSPFv3 is an interior gateway routing protocol, which is widely used in IPV6 environment. It is the realization of OSPFv2 for IPV4 in the IPV6 environment. They are the same in the basic principles. The paper uses the OPNET network simulation software to simulate and analyze the performance of OSPFv3, and found that both the convergence period is the same roughly, the flow is concentrated in the first...
Routing is one of the most challenging aspects in Delay Tolerant Networks (DTN) because the end-to-end path does not always occur. In wildlife tracking, habitat monitoring, and other scenarios, the network area may be divided into some geographical communities, the nodes only move in their communities. In this paper, for this specific community-based DTN, we address the delivery delay of the epidemic...
Now the address assignment mechanism of wireless sensor network has a limitation on supporting large scale sensor network that is consisted of more than hundreds of nodes. A distributed address assignment that is indicated in ZigBee Alliance, the standard group related to WSN is a method assigning the address by dividing address area of 16bit into regular blocks according to the depth. But this method...
Network-on-chip (NoC) has been proposed for SoC (System-on-Chip) as an alternative to on-chip bus-based interconnects to achieve better performance and lower energy consumption. Several approaches have been proposed to deal with NoCs design and can be classified into two main categories, design-time approaches and run-time approaches. Design-time approaches are generally tailored for an application...
In order to research the influence of the transport demand distribution on the transport capacity. This paper predicts the transport demand by introducing the gravity model, and explains how the impedance of distance affect the transport capacity. Our numerical study indicates that the distance distribution between vertices with transport demand follows exponential decay, furthermore the distribution...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
Networks on chips (NoCs) provide a mechanism for handling complex communications in the next generation of integrated circuits. At the same time, lower yield in nano-technology, makes self repair communication channels a necessity in design of digital systems. This paper proposes a reliable NoC architecture based on specific application mapped onto an NoC. This architecture is capable of recovering...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
