Using classical molecular dynamics simulations, we have studied thermal boundary conductance (TBC) between a single-walled carbon nanotube (SWNT) and surrounding Lennard-Jones (LJ) fluids. With an aim to identify a general model that explains the TBC for various surrounding materials, TBC was calculated for three different surrounding LJ fluids, hydrogen, nitrogen, and argon in supercritical ph...

Tuberculosis (TBC), caused by the bacterium My tuberculosis (Mtb), is a growing international health crisis [1]. TBC is one of the main causes of death produced by infectious illness and is responsible for almost 3 millions deaths every year [2]. In this study, a controlled Expert System (ES) have designed to diagnosis of TBC and truth table have created by considering the probabilities of TBC ...

Single-walled carbon nanotubes (SWNTs) are expected to be used in various electrical and thermal device applications. In particular, the thermal boundary conductance (TBC) K between an SWNT and surrounding fluid –the inverse of thermal boundary resistance (TBR)– is one of the most important characteristics for thermal managements of SWNTs in various fields. The cooling rate of SWNTs in electron...

INTRODUCTION Cutaneous tuberculosis (TBC) is a chronic disease caused by Mycobacterium tuberculosis, and is present in less than 1-2% of all TBC cases. The current problem with diagnosis is the demonstration of bacillus in the skin, especially paucibacillar forms, where sources like polymerase chain reaction (PCR) have improved diagnostic capacity. CASE PRESENTATION Two cases of cutaneous TBC...

Based on the loss distribution and efficiency analysis, a comparative study between a series resonant three-port bidirectional DC-DC converter (SR-TBC) and a multi-resonant three-port bi-directional DC-DC converter (MR-TBC) is reported here. By using the Fourier equivalent analysis method in hand, the resonant current, switching current expressions, zero voltage soft switching (ZVS) conditions ...

Thermal barrier coating (TBC) systems are susceptible to delamination failures in the presence of a large thermal gradient. These failures, which occur within the TBC layer, are very different in character from those associated with the thermally grown oxide. Three possible causes of internal delamination are analyzed. In all cases, the thermomechanical properties of the TBC are allowed to vary...

Nondestructive evaluation (NDE) methods are being developed at Argonne National Laboratory for thermal barrier coatings (TBCs) applied to components in the hot-gas path of advanced high-efficiency and low-emission gas turbines, including syn-gas fired turbines. As TBCs become “prime reliant,” it becomes important to know their conditions nondestructively to assure the reliability of these compo...
