Crystallization of semiflexible polymers in melts and solutions

We studied the crystallization of semiflexible polymer chains in melts and poor-solvent solutions with different concentrations by dissipative particle dynamics (DPD) computer simulation technique.

Hydrogen Line Shapes in Plasmas with Large Magnetic Fields

We report on hydrogen line shape calculations in the presence of an external magnetic field, at conditions such that the quadratic Zeeman effect is important. The latter is described through a term proportional to B2 in the Hamiltonian, accounting for atomic diamagnetism. It provides a shift and an asymmetry on Lorentz triplets, and it leads to the occurrence of forbidden components. Motivated by investigations performed at the fifth edition of the Spectral Line Shape in Plasmas (SLSP5) code comparison workshop, we perform new calculations of hydrogen Lyman line profiles. Field values representative of magnetized white dwarf atmosphere conditions are taken. The calculations are done using a computer simulation technique, designed for Stark broadening modeling. A discussion of the results is done in the framework of plasma diagnostics.

Microstrip Spork Patch Antenna for Integration Into Wearable Textile Substrates for ISM Band Applications

A Wearable textile antenna is meant to be a part of clothing used for communication purposes like tracking, navigation, mobile computing and public safety’s .The invention of wearable textile antenna exhibited the need for wireless communication tools into garments. A Spork shaped patch textile antenna is designed and simulated for the operation at Industrial, Scientific and Medical (ISM) band applications. The textile patch antenna is simulated using Computer Simulation technique software (CST), the textile material and patch provides the antenna to work in the frequency range of 2.4-5.8 GHz.These bands include designated frequency band of wireless standards IEEE 802.11 and IEEE 802.11b, Bluetooth, The designed antenna exhibits good radiation pattern, return loss, and gain for ISM band.
