Brown dwarf populations in open clusters

We present the results of multiple simulations of open clusters, modelling the dynamics of a population of brown dwarf members. We consider the effects of a large range of primordial binary populations, including the possibilities of having brown dwarf members contained within a binary system. We also examine the effects of various cluster diameters and masses. Our examination of a population of w

New applications and developments of field-asymmetric ion mobility spectrometry - mass spectrometry (FAIMS-MS)

Field asymmetric ion mobility spectrometry (FAIMS), also commonly termed differential mobility spectrometry (DMS), is a gas-phase ion separation technology. FAIMS exploits differences in high-electric-field to low-electric-field ion mobility ratios to discriminate between ion species. FAIMS and mass spectrometry (MS) provide generally orthogonal ion separation and are easy to interface. One of the

Implementation Aspects of Antenna Selection for MIMO Systems

Antenna selection is a promising technique for reducing complexity of multiple-antenna (MIMO) systems. In antenna selection, more antenna elements than RF transceiver chains are available for up-conversion and down-conversion. A subset of the available antenna elements is selected and connected to the RF chains. The reduction in the number of RF chains helps to reduce the implementation cost of mu

Analysis of compact heat exchangers as an intercooler in pemfc systems

In Proton Exchange Membrane Fuel Cell (PEMFC) systems, an intercooler contributes to proper thermal management of the reactant air into the cathode. However, the structure/performance of it is not clear yet. In this paper, two case studies concerning an intercooler in a 100 kW PEMFC system are carried out. Plate-fin and tube-fin heat exchangers are analyzed as the intercooler, in terms of volume,

Anisotropic Protein Interactions in Salt Solutions and at Interfaces: Coarse Grained Modeling

Popular Abstract in English Proteins are molecular machines of the human body which regulate all life sustaining processes such as energy production, communication, transport of essential molecules, defense against microbes, etc. They are built by small molecular units called amino acids, bound together like pearls on a necklace. Each amino acid consists of a common part and a unique side chain. TAnisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. In this thesis, we have studied the effect of anisotropic interactions on the behavior of various proteins mainly
