Wireless computer networks have properties that differ significantly from traditional wireline networks. One prominent difference is the presence of unidirectional channels. That is, it may be possible for a computer p to send a message to a neighboring computer q, but it may not be possible for computer q to send a message to computer p. This introduces significant changes in routing protocols...

We examine a decomposition approach to find good quality feasible solutions. In particular, we study a method to reduce the search-space by decomposing a problem into two partitions, where the second partition (i.e., the subproblem) contains the fixed solution of the first (i.e., the master). This type of approach is usually motivated by the presence of two sub-problems that are each more easil...

We studied the phase-transition induced texture changes and strengthening mechanism for zirconium metal under quasi-hydrostatic compression and uni-axial deformation under confined high pressure using the deformation-DIA (D-DIA) apparatus. It is shown that the experimentally obtained texture for ω-phase Zr can be qualitatively described by combining a subset of orientation variants previously p...

This paper investigates causal relations between economic growth, income inequality, and transmission channels during the period 1972 to 2016. These channels include saving rate, investment rate, redistribution policies, human capital, and conspicuous consumption. There is no strong evidence that supports uni-directional or bi-directional causality. In addition, some of the transmission channel...

1 Editorial Current day Hallyu (Korean wave) culture is rapidly spreading throughout Asia and the world, moving from the periphery of global culture towards the center. 'Plastic Surgery Hallyu' has joined K-pop, TV dramas, dancing, and food as one of the pillars of the Hallyu craze, and the Korean Society of Plastic and Reconstructive Surgeons (KSPRS) is showing the world its outstanding result...

Link state routing protocols such as OSPF and IS IS are widely used in the Internet today In link state routing protocols global network topology information is rst collected at each node A shortest path tree SPT is then constructed by applying the Dijkstra s shortest path algorithm at each node Link state protocols usually require the ooding of new information to the entire sub network after c...

We investigate reliable multicast communication over satellite networks. We compare a scenario where receivers can use a feedback channel to signal loss to a scenario where no feedback channel is available. We show that the introduction of a feedback channel is the key to allow for bandwidth-e cient, robust, and fully reliable multicast communication via satellite.

This paper presents a new technique for accurately modeling uni-directional High-Voltage lightly-doped-drain MOS (HV MOS) devices by extending the bi-directional HV MOS model and adopting a new parameter extraction method. We have already reported on a SPICE model for bi-directional HV MOS devices based on BSIM3v3. However, if we apply this bi-directional HV MOS model and its parameter extracti...
