A common technique to exploit data level parallelism is code vectorization. When performed by a compiler, it needs to find a valid vectorization and assess its benefit. In LLVM, this analysis is based on a cost calculation, which will approve the transformation if the cost of the vectorized code is lower than the original scalar code. However, the calculated cost does not correlate to the actua...

This research performs the advanced exergy and exergoeconomic analyses of a combined cycle power plant (CCPP) located in Zavareh, Iran. The objective of this research is to evaluate the irreversibilities, their related cost rates of each part of the CCPP that can be avoided and the inefficiencies of each part that caused by other components. The advanced exergy and exergoeconomic analyses indic...

We investigate the energy consumption and seek-time performance of different actuator types for nanopositioners, with emphasis on their use in a parallel-probe-based data-storage system. Analytical models are derived to calculate the energy consumption and performance of electrodynamic (coil and permanent magnet) and comb-drive actuators. The equations are used to simulate the operation of prob...

Higher-powered electronics are being integrated into automobiles rapidly. With these electronics comes a problem of how to cool this equipment economically. Heatsink costs have not benefited nor adapted to the high volume nature of automotive electronics. Specially shaped heatsinks are much more efficient for a given size than aluminum extrusion-based ones, most prevalent used in automobiles. H...

Clusters of Personal Computers have been proposed as potential replacements for expensive compute servers. One limitation in the overall performance is the interconnection network. A possible solution is to use multiple processors on each node of the PC cluster. Parallel programs can then use the fast shared memory to exchange data within a node, and access the interconnection network to commun...

The railroad network carries 40 % of the freight in the US. Railroad bridges are the most critical part of the network and they need to be properly maintained for safety of operations. Railroad managers inspect the bridges to assess their structural condition. Railroad managers are interested in measuring displacements under train crossing events to prioritize their bridge management and safety...

This paper addresses strategies for improving delivery performance in a serial supply chain when delivery performance is evaluated with respect to a delivery window. Contemporary management theories advocate the reduction of variance as a key step in improving the overall performance of a system. Models are developed that incorporate the variability found in the individual stages of the supply ...

in management accounting information systems, managers use accounting information systems to be able to predict or have the data structured by the use of decision support systems and business intelligence. so, the use of management accounting information systems is necessary in management decision-making process based on decision support and business intelligence. this paper reviews the liter...
