In this paper, we investigate the performance of passive and active recirculating fibre loop buffers (RFLB) in an optical time division multiplexing (OTDM) network employing soliton pulse shape. Both standard fibre and dispersion shifted fibre (DSF) are considered. Further to previous work [1], it is no longer assumed that switching mechanism is ideal, and both insertion loss and crosstalk are ...

Disk-based database systems use buffer managers in order to transparently manage data sets larger than main memory. This traditional approach is effective at minimizing the number of I/O operations, but is also the major source of overhead in comparison with in-memory systems. To avoid this overhead, in-memory database systems therefore abandon buffer management altogether, which makes handling...

Abstract As the power dissipation has become one of the critical design challenges in a sensor network environment, nonvolatile memories such as STT-MRAM and flash memory will be used in the next generat...

We report on the use of protic ionic liquids, pILs, as solvents for the solubilisation and stabilization of viruses. We show that the shelf life of the pIL stabilized tobacco mosaic virus is significantly enhanced when compared to traditional phosphate buffer. This has new opportunities for the preparation, characterization and storage of viruses and virus based technologies.

TLP retry mechanism is an effective measure of PCI Express to ensure data reliable transmissions. The paper theoretically analyzes reasons for retransmission, operating rules of retransmission and factors affecting the size of retry buffer. On this basis, proposes a circuit structure of implementing TLP retry mechanisms, describing the implementation process of retry management, and conducts fu...

In this paper, we consider the problem of buffer space allocation for a tandem production line with unreliable machines. This problem has various formulations all aiming to answer the question: how much buffer storage to allocate between the processing stations? Many authors use the knapsack-type formulation of this problem. We investigate the problem with a broader statement. The criterion dep...

Disk based storage systems serving continuous media content are evaluated using metrics such as startup latency, buffer size, and the number of concurrent streams. The design of a practical system must evaluate the tradeoffs among these parameters to achieve a target system performance while minimizing operational costs. In this paper, we describe a generic model that can be used for characteri...

The electric power grid is a vital network for every aspect of our life. The lack of buffer between generation and consumption makes the power grid unstable and fragile. While large scale power storage is not technically and economically feasible at present stage, we argue that a virtual buffer could be effectively implemented through a demand side management strategy built upon the concept of ...

In container terminal operations, the storage yard plays an important role for a terminal’s overall performance because it links the seaside and landside and serves as the buffer area for storing containers. Therefore, storage and stacking logistics has become a field that increasingly attracts attentions in both academic and practical research during the recent years. The purpose of this artic...

Large-grain synchronous dataflow graphs or multi-rate graphs have the distinct feature that the nodes of the dataflow graph fire at different rates. Such multi-rate large-grain dataflow graphs have been widely regarded as a powerful programming model for DSP applications. In this paper we propose a method to minimize buffer storage requirement in constructing rate-optimal compile-time (MBRO) sc...
