Synthetic noncrystalline aluminosilicates with variable charge, similar to allophanes present naturally in volcanic soils, were studied. The surface charge behavior was determined by zero point charge (ZPC) measured by electrophoretic mobility (isoelectric points, IEP) and determined by potentiometric titration (point of zero salt effect, PZSE). The ZPC calculated by Parks model (ZPC(c)), compa...

This paper presents a 3D transmission line matrix (TLM) implementation for the solution of transient heat flow in power devices. The miniaturization of electronic networks creates problems of heat dissipation. Good thermal management is therefore essential. Simulating power electronic systems presents peculiar challenges due to the need of detailed modeling of both circuitry and control algorit...

OBJECTIVE To report the oncologic and functional outcomes of transoral laser microsurgery (TLM) in the treatment of advanced laryngeal cancer. DESIGN Prospective case series study. SETTING Multi-institution (academic, tertiary referral centers). PATIENTS A total of 117 patients with pathologically confirmed T2 to T4 lesions, stage III or stage IV, glottic or supraglottic carcinoma of the ...

Analogues of the antibiotic thiolactomycin (TLM) have been synthesized and have been shown to have enhanced activity against whole cells of Mycobacterium tuberculosis H37Rv and against mycolic acid biosynthesis in cell extracts of Mycobacterium smegmatis. TLM has a methyl-branched butadienyl side chain attached at position 5 on a 'thiolactone' ring, namely 4-hydroxy-3,5-dimethyl-5H-thiophen-2-o...

A new technique which allows the simulation of thin ferrite absorbing tiles in a coarse TLM mesh is described. Results are presented which show a good fit to manufacturers' reflectivity curves. Experimental and simulation results for a screened room partially lined with ferrite are presented to demonstrate the accuracy of the method. INTRODUCTION The Transmission Line Matrix (TLM) method of num...

The accurate simulation and emulation of mobile radios requires the computation of RF propagation path loss in order to accurately predict connectivity and signal interference. There are many algorithms available for computing the RF propagation path loss between wireless devices including the LongleyRice model, the transmission line matrix (TLM), ray-tracing, and the parabolic equation method....

With everyday growing demands, complexity of electronic devices has been constantly increasing. Functional verification has become the major bottleneck in the design and verification flow. In order to respond to modern demands, new devices are made of standard pre-verified reusable IP blocks created by using abstract TLM. The paper proposes a three-step design and verification flow based on a r...
