30 patients were randomised each into the four-port and two-port
. Out of three patients, two in the four-port group and one in the two-port
group were lost to follow-up.
This behaviour of the two-port
equivalent diagram can be symbolized as [1.sup.*] [right arrow] 2, respectively 2 [not right arrow] [1.sup.*], where the asterisk shows that the circuit is supplied from port 11' to port 22' .
Treated as a two-port
network, this impedance is described by the impedance matrix
KEY WORDS: Limited Two-Port
Thoracoscopy Spontaneous pneumothorax Video assisted thoracic surgery.
When the low frequency regime is considered, and plane wave propagation is assumed, this approach leads to the two-port
The optional software will expand the measurement capabilities to include key VNA field measurements, including full-reversing two-port
S-parameters and time domain with gating.
Instead of the aperture-coupled patch elements, two-port
aperture-coupled stacked-patch (ASP) antennas have been designed as the array elements and the conventional ASP antenna  is applied as the radiating matched load.
Unlike the description of the properties of common two-port
as used in circuit theory, in the case of power line description the output current [I.sub.2] is of opposite direction.
The M29312 two-port
DS3/E3 line card-on-a-chip (LoC) from Mindspeed Technologies Inc (Nasdaq:MSPD), a supplier of semiconductor solutions for network infrastructure applications, has been selected by ZTE Corporation, a telecomms equipment and network solutions provider.
The new version 2.43's data extraction facility controls a standard single-ended transmission-reflection analyzer or two-port
S-parameter vector network analyzer to generate multi-port data.
EZ-Host (CY7C67300) is a multiport controller featuring two individually configurable two-port
serial interface engines (SIEs) and a configurable I/O block that can connect to numerous standard interfaces.
These flange-type two-port
ball valves are designed to provide a simple way to install a two-port
ball valve in a circuit that uses any SAE four-bolt flange-mounting pattern.
