the dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. with the help of displacements and stresses green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...

In order to increase the gain of patch antenna , a Mushroom-like EBG(Electromagnetic Band Gap ) structure is used . EBG structures enhance antenna’s characteristics directivity, bandwidth and efficiency Initially, we determined frequency band gap mushroom-like unit cell value by using ANSYS software The periodic arrangement such was not limited any inter connecting microstrip lines Different pa...

in this contribution, a MIMO micro strip patch antenna with four radiating elements is designed3 at 28 GHz. The designed has very low isolation loss between elements. simulated using the CST Microwave simulator. measurement results are also shown paper. Both simulation and studied to analyze performance of antenna. features such as, return loss, VSWR, gain, beam-width radiation pattern analyzed...

Accurate land cover data are essential to a reliable decision-making process; therefore, researchers have turned novel classification algorithms employing machine learning on high-resolution satellite imagery improve accuracy. The experiment presented in this paper aims assess the accuracy performance of three patch-based, convolutional neural network architectures (LeNet, VGGNet, and XCeption)...

The interactive effects of predator density and prey distribution on the foraging behavior of an important estuarine predator were studied, at a fine temporal scale, using ultrasonic telemetry. The movement and agonistic activity of individual blue crabs Callinectes sapidus were monitored in large field enclosures, in which the density of crabs and the distribution of patches of bivalve prey Ma...

This paper proposes a simple novel technique for self-isolating MIMO antenna mm-wave applications. elements with inter-element separation of 0.2 mm ( $0.023\lambda $ at 35 GHz) and measured high isolation (>50 dB) are presented. By ob...

Marine protected areas are commonly seen as the most effective strategy for protecting mangroves from external human pressures but little is known about the role of public land-tenure contexts (dense settlements, agricultural or range lands and wild anthromes) on clearing rates, patch properties, and ecological condition. We addressed the following questions using a peri-urban to wild gradient ...

Background Obtaining hemostasis during cardiovascular procedures can be a challenge, particularly around areas with a complex geometry or that are difficult to access. While several topical hemostats are currently on the market, most have caveats that limit their use in certain clinical scenarios such as pulsatile arterial bleeding. The aim of this study was to assess the effectiveness and safe...
