A new hybrid flow shop scheduling problem with blocking is studied. The problem is characterized by multistage unrelated parallel machines and no intermediate buffer. Firstly, the math model of the hybrid scheduling problem is constructed. And then the computation method of production period is given. Due to there is no intermediate buffer, and there are unrelated parallel machines in multi-sta...

To date, data locality optimizing algorithms mostly aim at providing strategies for blocking and reordering loops. But little research has been devoted to the nal step: nding the optimal block size, i.e., a block size that provides the best possible performance. Optimal block sizes are currently computed as if a cache is a local memory, i.e., cache interferences are ignored. Case-studies have a...

A VOD server handles various types of media such as continuous media (CM) and non-continuous media (NM). Conventional VOD server buffer scheduling algorithms like Round Robin (RR) and Earliest Deadline First (EDF) have tradeoffs between guaranteeing the deadline of CM and getting a fast response time of NM. The former performs well in a NM environment while the latter is suitable for CM. In thi...

This paper reports the successful fabrication of a GaN-on-Si high electron mobility transistor (HEMT) with a 1702 V breakdown voltage (BV) and low current collapse. The strain and threading dislocation density were well-controlled by 100 pairs of AlN/GaN superlattice buffer layers. Relative to the carbon-doped GaN spacer layer, we grew the AlGaN back barrier layer at a high temperature, resulti...

BACKGROUND Heterophilic antibodies are a common source of interference in immunometric assays. We tested the hypothesis that the incidence of such interference could be decreased by use of a recombinant in vivo-biotinylated single-chain antibody (scFv) as the capture reagent. METHODS We established three assays for carcinoembryonic antigen (CEA) with the capture antibody either chemically bio...

To make comprehensive and objective analysis of the performance of the cloud computing system center, a cloud computing center system analysis model based on queuing theory is proposed. First, to describe the characteristics of user’s service changes request arrived at center by using Poisson distribution, the batch arrival system model was established based on queuing theory, then solve the st...

In this paper, quality-of-service (QoS) guarantees for multiclass code division multiple access networks are provided by means of cross-layer optimization across the physical and network layers. At the physical layer, the QoS requirements are specified in terms of a target signal-to-interference ratio (SIR) requirement, and optimal target powers are dynamically adjusted according to the current...

Zero Queueing Flow Control (ZQFC) is a new credit-based flow control method for ATM networks. The receiving node of such a flow-controlled link will have zero queue-occupancy in the steady state. ZQFC uses both link and VC flow control simultaneously over the link to implement the required rate adaptation for achieving zero queueing. Because of its zero queueing property, ZQFC is able to solve ...

1. ATP receptors of the P2X class have previously been identified on autonomic nerve endings and on a limited population of CNS neurons. 2. In the present study P2X receptors on mammalian cortical synaptosomes have been identified by a variety of functional and biochemical studies. In choline buffer ATP analogues caused concentration/time dependent Ca(2+) influx. Relative to the effects caused ...
