Sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. But square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

In this paper, we present a new technique to improve the reliability of SRAMs used in space radiation environments. This technique deals with the SRAM power-bus monitoring by using Built-In Current Sensor (BICS) circuits that detect abnormal current dissipation in the memory power-bus. This abnormal current is the result of a single-event upset (SEU) in the memory and it is generated during the...

background: fluoride-18 is the most widely used radioisotope for positron emission tomography (pet). [18f] 2-flouro- 2-deoxy d-glucose (fdg) has become a standard tool in the area of clinical research. the oxygen-18 enriched water is the most widely used target for the production of fluoride-18. the use of the nuclear reaction 18o (p,n)18f has been found as the most effective method for the pro...

This paper discusses an algorithm for nding a distance map for an image e ciently using an optical bus. The computational model considered is the arrays with a recon gurable pipelined bus system (LARPBS), which is introduced recently based on current electronic and optical technologies. It is shown that the problem for an n n image can be implemented in O(log n log log n) time deterministically...

P-V or Q-V curve are commonly used to determine the maximum permissible load or static voltage stability limit of a power system. Voltage versus current relation approximation is presented as a tool to assessThe voltage stability limit.determination of the maximum permissible loading of a power system is essential for operating the system with an adequate security margin. A very simple and stra...

an approach for assignment of the optimal location and tap changer adjustment related to flux-lock type superconducting fault current limiters with tap changer (tc-flsfcl) is used in this paper by debating the reduction of fault current flowing from each device and enhancement of reliability varying with customer type in a distribution network connected with distribution generation (dg). tc-fls...

In chip-multiprocessors (CMP) architecture, the L2 cache is shared by the L1 cache of each processor core, resulting in a high volume of diverse data transfer through the L1-L2 cache bus. High-performance CMP and SoC systems have a significant amount of data transfer between the on-chip L2 cache and the L3 cache of off-chip memory through the power expensive off-chip memory bus. This paper addr...
