The objective of this work is to establish the basic setup and methodology for analyzing the effect of common disturbances on the residential power line channel response regarding time and network topology. Such information is necessary in the process of developing a method of real-time channel sensing used in a multi-carrier communication system that performs dynamical sub-channel bandwidth al...

A foreign body near the bladder is rare. Although foreign bodies in the bladder can be easily found and removed by endoscopic transurethral removal, extravesical foreign bodies may require the use of an open or laparoscopic procedure. Here, we report a case of a patient complaining of frequency and urgency in whom an extravesical sewing needle was successfully removed by a laparoscopic approach...

ions A first-order abstraction in the ρpg-calculus consists of two object port graphs for the leftand the right-hand sides, and an arrow node embedding the correspondence between the two sides. The arrow node has two particular ports, a handler port p0 and a black hole port bh. Some restrictions must be imposed on the connectivity of these two types of ports. A handler port can be connected onl...

Background In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. Methods A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2...

Aiming at the internal leakage problem of spring type nuclear safety valve sealing surface, flow field and sound characteristics height 0.5mm between disc seat surface were studied, numerical simulation was carried out based on large eddy simulation(LES) mohring acoustic analogy method, compare effects wall pressure fluctuation(AWPF) turbulent fluctuation(TWPF) as excitation source external val...

In this Application Note we show three system configurations for recovery collection with the Agilent 1100 Series purification system. One configuration uses a 12-position/13-port valve 3 in the waste line of the fraction collector, which offers up to twelve recovery locations. Another possibility is to use a third-party fraction collector, controlled by the ChemStation through external contact...

This application note describes how to alter the printed wiring board (PWB) netlist of a design containing the DS33R41 Inverse-Multiplexing Ethernet Mapper with Integrated Quad Port T1/E1/J1 Transceiver so that the netlist complies with the Joint Test Action Group (JTAG) specifications. These changes are necessary because the DS33R41 was designed as a multichip module with multiple die in a sin...

This paper addresses the problem of equal distribution of a satellite constellation on a circular target orbit. The control goal is to make a satellite constellation converge to a circular target orbit, while spatially distributing the satellites. The solution is defined in the port-Hamiltonian framework, which provides a clear physical interpretation of the control laws. The controller consist...

The prediction of RF properties of complex accelerating structures is an important issue in computational accelerator physics. This paper describes the derivation of state space equations for complex structures based on real eigenmodes of sections of the decomposed complex structure. The state space equations enable the calculation of system responses due to port excitations by means of standar...

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...
