Passenger seaports are new starting-points of urban development. They form a independent industry, become incentives for improving infrastructure and increase the tourist attractiveness city itself region. In view changes in passenger service processes, route ferry cruise networks, due to COVID-19, heads ports terminals set strategic tasks determine directions modernization forecast The regions...

When testing a system that has multiple physically distributed ports/interfaces it is normal to place a tester at each port. Each tester observes only the events at its port and it is known that this can lead to additional controllability problems. While such controllability problems can be overcome by the exchange of external coordination messages between the testers, this requires the deploym...

The present article expounds a formalism for the representation of multi-port non-reciprocal antenna structures in an arbitrary surrounding linear medium. In the most general approach the antenna, the waveguides connected to it, as well as the surrounding medium may contain any distribution of anisotropic magneto-electric media. Furthermore, an arbitrary external field is taken into considerati...

We propose a hybrid scattering parameter matrix for concurrent on & off – board EMI analysis of mixed RF-Digital Circuits. To start with, we first consider on–board EMI effects on digital circuits, particularly on an inverter to show the vulnerability of digital devices to RF interference and investigate both system and device level upsets due to adjacent EMI sources on Printed Circuit Boards (...

The extracellular colorants produced by Chlorociboria aeruginosa, Scytalidium cuboideum, and Scytalidium ganodermophthorum, three commonly utilized spalting fungi, were tested against a standard woodworker's aniline dye to determine if the fungal colorants could be utilized in an effort to find a naturally occurring replacement for the synthetic dye. Fungal colorants were delivered in two metho...

peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

evidence acquisition a systematic literature searching of databases medline, embase, and google scholar was done from 1982 and updated in december 2015. search terms were “cholecystectomy”, “laparoscopic cholecystectomy”, “four port laparoscopic cholecystectomy”, “single-incision laparoscopic surgery”. context laparoscopic approach with its several techniques has become the standard method for ...

Ports are important hubs that have positive impacts on the regions they serve, but also pose some challenges need to be addressed. Many ports around world aligned their development strategies with concept of green growth; however, and efficient performance does not only depend port management itself; elements negotiated approved by local national governments. One such is road access. We investi...

A simple algorithm is presented for evaluating scattering parameters of a two-port network. This technique uses the indefinite admittance matrix to calculate scattering or any other desired set of two-port parameters.
