Little is known about the neural systems that subserve human loss aversion. A recent neuroimaging study by Tom, Poldrack and colleagues reports that this pattern of behaviour is directly tied to the greater sensitivity of the brain to potential losses compared with potential gains and uncovers a brain network whose activity increases with potential gains and decreases with potential losses. The...

Abstract. This paper analyzes the voice transmission capacity in mobile ad hoc networks by performing simulations related to end-to-end delay, jitter, and the number of consecutive losses. We evaluate the influence of mobility and nodes density on the number of voice transmitting sources. Results show that the network capacity for voice transmission in multihop mobile networks decreases, down t...

Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...

As Internet usage grows, more efforts are put into analyzing its internal performance, usually such analysis comes through simulation using different models. While simulation can provide a good approximation of network behavior, modeling such a complex network as the Internet is very difficult if not impossible. This paper studies the network’s performance from an experimental point of view usi...

In a wired network, most packet losses are due to congestion. TCP exploits this characteristic of wired networks and is tuned to perform well in such an environment. But in a wireless environment, losses due to errors over the wireless hop also contribute signiicantly to the cumulative packet losses. If TCP is used ov er a wireless link, then its performance is severely degraded. In this paper,...

TCP optimization for wireless networks to deal with packet losses due to fading, shadowing and contention should preferably maintain TCP end-to-end semantics with minimal dependence on intermediate nodes. The development of advanced 3G networks and services makes it necessary to find a way of improving TCP’s efficiency and resource utilization. Previous research on this issue suggests that TCP ...

Different load centers where the energy is utilized are connected to the generating stations through high voltage transmission systems and a low voltage distribution systems. The losses occurring in the distribution network amount to nearly 40% of the total losses. Optimally located Distributed Generation (DG) systems offer multiple benefits in reducing the losses and supplying quality power. I...
