—Tasks scheduling problem is a key factor for a distributed system in order to achieve better efficiency. The problem of tasks scheduling in a distributed system can be stated as allocating tasks to the processor of each computer. The objective of this problem is minimizing makespan and communication cost, while maximizing CPU utilization. Scheduling(More)
– Todays, computer networks play a very important role in our daily activities. In order to have a better network management, data packet problems, should be considerably reduced. One of the most important problems that happens in networks and is not recognizable easily, is congestion, That encouraged experts to research more about this topic. Congestion(More)
The use of phenolic or melaminic bakelite as RPC electrodes is widespread. The electrode resistivity is an important parameter for the RPC performance. As recent studies pointed out, the bakelite resistivity changes with temperature and is in#uenced by humidity. In order to gain a quantitative understanding on the in#uence of temperature and humidity on RPC(More)
The mechanism of resource allocation plays a vital role in maximizing the network utilization and serving the requesting nodes. This idea can be effectively demonstrated using the concept of network virtualization. Through Network virtualization an environment conducive to perform tests using similar network conditions , applications and dependencies can be(More)
The aim of the present paper is to identify the main Raman vibrational features of carbon nanotubes and derivatives. In this goal, Raman active mode calculations have been performed on different single-walled carbon nanotubes (SWCNTs) and double-walled carbon nanotubes (DWCNTs) as well as peapods. The comparison between the calculations performed on these(More)
We present a force constants model for the vibrational modes in C60 dimer and polymer phases. The results of this model are used to calculate the nonresonant Raman spectra of infinitely long isolated C60 dimer and polymer peapod in the framework of bond-polarization theory by using the spectral moment's method. The changes of the Raman spectrum in terms of(More)
Using the spectral moments method, we present calculations of Raman active modes of Single Walled Boron Nitride Nanotube (SW-BNNT). The Spectra are computed for chiral and achiral nanotubes in terms of their diameter and length. The behaviors of low frequency Raman active modes characteristic, in terms of the tube diameter revealed that these frequencies(More)
In the present work, the non-resonant Raman-active modes are calculated for several diameters, chiralities and sizes for homogeneous and inhomogeneous bundles of single-walled carbon nanotubes (BWCNTs), using the spectral moment's method (SMM). Additional intense Raman-active modes are present in the breathing-like modes (BLM) spectra of these systems in(More)
