Interval routing is a space-efficient routing method for computer networks. The method is said to be optimal if it can generate optimal routing paths for any source-destination node pair. A path is optimal if it is a shortest path between the two nodes involved. A seminal result (The Computer Journal, 34 (1991), 475–476) in the area, however, has pointed out that “the interval routing algorithm...

Deep Convolutional Neural Networks (CNNs) are capable of learning unprecedentedly effective features from images. Some researchers have struggled to enhance the parameters’ efficiency using grouped convolution. However, the relation between the optimal number of convolutional groups and the recognition performance remains an open problem. In this paper, we propose a series of Basic Units (BUs) ...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...

I study the general equilibrium implications of large-scale policies to improve energy efficiency, which are being implemented around the world to mitigate climate change. Energy efficiency policies “rebound” when economic responses undercut their direct energy savings. I develop an analytic general equilibrium framework that allows improvements in energy efficiency to affect output prices and ...
