Abstract Truss-like lightweight materials (TLMs) have been widely used in aeronautics and astronautics, because of excellent mechanical property superior energy absorption capability. The design TLMs’ meso-structures was a critical task to improve its performance. Hence, structure method based on the symmetric groups proposed for TLMs, novel hexagonal prism TLM’s meso-structure deduced by trans...

The transmission line matrix time domain (TLM-TD) method is used to simulate the electromagnetic pulse (EMP) coupled inside a shielding box with an aperture. Simulations for different electromagnetic pulses regarding to different rise time and fall time have been performed. The results for shielding effectiveness of these different excitations have been presented. A simple method that uses an e...

BACKGROUND Surgical treatment options for local recurrences of laryngeal cancer can be either organ-preserving surgery or total laryngectomy. The purpose of this study was to present our evaluation of the treatment with transoral laser microsurgery (TLM) in comparison to laryngectomy. METHODS We conducted a retrospective review of 199 consecutive patients with recurrent laryngeal cancer at 1 ...

This report describes ESE(Embedded System Environment), a tool set for modeling, synthesis and validation of MPSoC design. It is an answer to the modern design challenge, widening productivity gap. In the ESE design flow, the final implementation is obtained from the universal specification of a given system by automatic or semi-automatic refinement. Application, platform and their mapping serv...

Dual scattering channel (DSC) schemes generalize Johns’ TLM algorithm in replacing transmission lines with abstract scattering channels in terms of paired distributions. A well known merit of TLM schemes is unconditional stability, a property generally drawn upon passivity of linear transmission line networks. So the question arises, if DSC algorithms remain stable in a neat sense. It is shown ...

In this paper novel reflectarray antenna elements are proposed using aperture-coupled dielectric resonator antenna structures. Using these new structures, wide phase range and wide frequency bandwidth (up to 28.5%) with parallel and linear phase curves are obtained. In each case, an array consisting of 289 elements was simulated using the finite integration technique (FIT). The arrays exhibit 3...

A detection and fixation method of single and multiple gold nanoparticles on the wall of a microfluidic channel is demonstrated. A thermal lens microscope (TLM) with continuous-wave excitation (wavelength, 532 nm) and probe (wavelength, 670 nm) laser beams was used to realize the sensitive detection of heat generated by light absorption of individual gold nanoparticles (50 nm in diameter); fixa...

─ This paper deals with an impact of receiving antenna placed in a metal enclosure on an electromagnetic field distribution within the enclosure, and thus on its shielding effectiveness. In an experimental setup, a frequently used tool for measuring the electromagnetic field level at certain points within the enclosure is a dipole antenna connected to a measuring instrument via a coaxial cable....

Transoral laser microsurgery (TLM) is an important option in the treatment plan for tumors of the oral cavity, oropharynx, larynx, and hypopharynx. For properly selected patients, TLM provides equivalent oncologic outcomes when compared to traditional therapies, while improving the functional aspects of postoperative speech, voice and swallowing.
