Chipless RFID systems can be considered as a special case of passive systems, where the tag contains no power source and electronics. Instead, tag’s information is stored in its structure accessed through electromagnetic (EM) scattering response. However, robust response detection, which primarily function measurement method, equipment, processing method used, still major challenge chipl...

Many two-dimensional incompressible inviscid vortex flows can be simulated with high efficiency by means of the contour dynamics method. Several applications require the use of a hierarchical-element method (HEM), a modified version of the classical contour dynamics scheme by applying a fast multipole method, in order to accelerate the computations substantially. In this paper it is shown that ...

Hem-o-Lok clips (Weck Surgical Instruments, Teleflex Medical, Durham, NC, USA) are widely used in robot-assisted laparoscopic radical prostatectomy because of their easy application and secure clamping. To date, there have been some reports of intravesical migration of these clips causing urethral erosion, bladder neck contractures, and subsequent calculus formation. We report the first case of...

The cortical hem was first described as a potential signaling center at the telencephalic midline because of an enriched expression of multiple members of the Wnt and Bmp families of morphogens, and its position at the border between the presumptive cortex and the choroid plexus. There is now definitive evidence that the cortical hem is an organizing center in the telencephalon, and that it ins...

The most popular model used in automatic speech recognition is the hidden Markov model (HMM). Though good performance has been obtained with such models there are well known limitations in its ability to model speech. A variety of modifications to the standard HMM topology have been proposed to handle these problems. One approach is the factorial HMM. This paper introduces a new form of factori...

Radar is an important sensor for various types of intelligent agents. The increasing number radars implemented in agents makes interference between them a noteworthy issue. One method mitigation to limit the electromagnetic resources frequency and time domain used by radar. However, problems how many are necessary optimally utilize limited have not been addressed. In this paper, we take collisi...

Mobile telephone systems divide the coverage area among low transmitting power sectors. This allows the so-called frequency reuse between sectors: geographically “distant” sectors might employ the same electromagnetic frequencies, since the probability of interference between them is small. The electromagnetic frequencies available for mobile communications are very limited and their use is reg...

This paper introduces a novel passive suspension system for ground vehicles. This system is based on a flexible Electromagnetic Shock Absorber (EMSA). In the proposed system, efforts are made to a) select a high damping coefficient usable in a car b) determine Physical dimensions and geometry not much different from those of the mechanical shock absorbers and c) seletct EMSA weight and volume l...

High-speed electronic circuits are becoming more and more important in modern communication systems, thus leading to an increasing interest in printed circuit boards, interconnect, and packaging. Nowadays, full-wave numerical methods are widely used in order to investigate both signal integrity and electromagnetic compatibility issues arising in PCBs design. When broadband information is desire...
