Brain Network Analysis: Separating Cost from Topology Using Cost-Integration

Brain Network Analysis: Separating Cost from Topology Using Cost-Integration

A statistically principled way of conducting brain network analysis is still lacking. Comparison of different populations of brain networks is hard because topology is inherently dependent on wiring cost, where cost is defined as the number of edges in an unweighted graph. In this paper, we evaluate the benefits and limitations associated with using cost-integrated topological metrics. Our focu...

Computer Network Time Synchronization using a Low Cost GPS Engine

Accurate and reliable time is necessary for financial and legal transactions, transportation, distribution systems, and many other applications. Time synchronization protocols such as NTP (the Network Time Protocol) have kept clocks of such applications synchronized to each other for many years. Nowadays there are many commercial GPS based NTP time server products at the market but they almost ...

Performance and Cost Metrics Analysis of a 3D NoC Topology using Network Calculus

The packet switching based Network-on-Chip (NoC) is an obvious interconnect design alternative to the shared bus, crossbar or ring based on-chip communication architecture used in System-on-Chips (SoCs). The advent of the three dimensional NoC (3D NoC) architecture attracts added interest as it offers improved performance and shorter global interconnect. In the 3D NoC architecture, topology pla...

Cost-Causation and Integration Cost Analysis for Variable Generation

Generalization of Decomposed Integration Methods for Cost Effective Heat Exchanger Networks with Multiple Cost Laws

At many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. In such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. In this research work a n...
