In this paper we propose a file replication scheme inspired by a thermal diffusion phenomenon for storage load balancing in unstructured peer-to-peer (P2P) file sharing networks. The proposed scheme is designed such that the storage utilization ratios of peers will be uniform, in the same way that the temperature in a field becomes uniform in a thermal diffusion phenomenon. The proposed scheme ...

Most of the Oil Pumping Units (OPU) are manually monitored. This existing oil-pumping systems use a high power-consuming process, is incapable of OPU’s structural health monitoring. In this paper, a sensor network based intelligent control is proposed for power economy and efficient oil well health monitoring. The condition of the oil storage tanks can be monitored using sensors like level sens...

Louisiana State University Center for Advanced Microstructures and Devices (CAMD) began a control system upgrade project in early 1997. At the time, the storage ring was controlled by a VAX/VMS system, primarily using CAMAC for I/O. The injector Linac was controlled by a separate VME/OS/9 system using custom I/O components. The storage ring control system has been replaced with a PC/Linux based...

Long term storage of a variety of crops as well as long-distance transport, has allowed meeting the consumers’ expectations in the supply of many types of fresh fruits and vegetables throughout the year. This is only possible with the use of several postharvest technologies. This chapter starts with a brief historical context followed by an overview of the technologies used for fruits and veget...

A dynamic range expansion technique for CMOS image sensors with dual charge storage in a pixel and multiple sampling technique is presented. Each pixel contains a photodiode and a storage diode which is connected to the photodiode via a separation gate. The sensitivity of the signal charge in the storage diode can be controlled either by a separation gate which limits the charge to flow into th...

lipoprotein-associated phospholipase a2 (lp-pla2) is produced by inflammatory cells, bound to ldl and other lipoproteins, and hydrolyzes oxidized phospholipids in ldl. type 2 diabetes is the most common form of diabetes some investigations show the association of lipoprotein-associated phospholipase a2 mass and activity with the incidence of cardiovascular disease (cvd) in populations with high...

In this paper, the transient stability of an electric power system is improved by fuzzy logic controlled superconducting magnetic energy storage (SMES). The effectiveness of the proposed fuzzy controlled SMES is compared with a conventional proportional integral (PI) controlled SMES. In addition to it a comparison between the fuzzy controlled SMES and fuzzy controlled braking resistor (BR) is a...

In this paper, we generalize the classical definition of passivity to discrete-time periodically controlled nonlinear systems that are open loop nonpassive and closed-loop feedback passive. In the classical passivity theory, a system is said to be passive if there exists a storage function such that the increase in storage function is bounded by the energy supplied to it at every time step. Thi...
