The procedure for analysis of electromagnetic field in a cylindrical metallic cavity, based on reflection and transmission characteristic, is presented in the paper. An analysis of procedure efficiency to resonant modes identification is conducted numerically and experimentally verified. As a numerical tool, TLM time-domain method, enhanced with the compact wire model to account for the presenc...

Intelligent vehicle design is a complex task which requires multidomains modeling and abstraction. Transaction-level modeling (TLM) and component-based software development approaches accelerate the process of an embedded system design and simulation and hence improve the overall productivity. On the other hand, system-level design languages facilitate the fast hardware synthesis at behavioral ...

The OVM and VMM methodologies each provide powerful, flexible and intuitive frameworks for the construction of SystemVerilog verification environments. However, many SystemVerilog users also have models written in C, C++, or sometimes SystemC. Furthermore, the emergence of the SystemC TLM-1 and TLM-2.0 transaction-level modeling standards is having an impact on communication styles within Syste...

Dual scattering channel schemes extend the transmission line matrix numerical method (Johns’ TLM algorithm) in two directions. For one point, transmission line links are replaced by abstract scattering channels in terms of paired distributions (characteristic impedances are thus neither needed, nor in general defined, e.g.). In the second place, non-trivial cell interface scattering is admitted...

Objective: Transoral laser microsurgery (TLM) for endoscopic excision of head and neck cancers of the upper aerodigestive tract has become an accepted treatment modality. As in any excision of head and neck tumors, the persistance of tumor at the surgical margins influences the outcome. One of the frequent criticisms of endoscopic resection is that the laser use makes interpretation of the surg...

To evaluate radiosensitivity and the effects of radiation on the expression of vascular endothelial growth factor (VEGF) and VEGF receptors in the canine oral melanoma cell line, TLM 1, cells were irradiated with doses of 0, 2, 4, 6, 8 and 10 Gray (Gy). Survival rates were then determined by a MTT assay, while vascular endothelial growth factor receptor (VEGFR)-1 and -2 expression was measured ...

Recently, transaction level modeling (TLM) has been widely referred to in system level design community. Due to lower modeling effort yet higher simulation speed, transaction level models are useful for architectural exploration, algorithmic evaluation, hardware-software partitioning and software development. However, TLM can’t be widely applicable to IP level design phase, because the simulati...

On the Printed Circuit Boards (PCBs), the interconnection geometry influences the ElectroMagnetic Compatibility (EMC) and the Signal Integrity (SI). The impact increases when circuits with a non-linear behavior are connected at their terminations. An accurate EMC analysis requires an electromagnetic solver including the model of those non-linear components. The insertion is made via lumped elem...

BACKGROUND The aim of this study was to screen various solvent extracts of whole plant of Torilis leptophylla to display potent antioxidant activity in vitro and in vivo, total phenolic and flavonoid contents in order to find possible sources for future novel antioxidants in food and pharmaceutical formulations. MATERIAL AND METHODS A detailed study was performed on the antioxidant activity o...
