As he threw the door open an old woman ran out in front of him and tried to bar his passage, but he thrust her back, and an instant afterwards we were all upon the stairs.
There being none left, he hurriedly caught up the empty bottle, and ran out at the door.
The planar array provides the ground path for each capacitor; a compliant grounding spring connects the array to the connector shell.
RAY: That might not be the worst acronym ever, but it deserves a nomination, along with: PUMCODOXPURSACOMLOPOLAR, which stands for Pulse Modulated Coherent Doppler-Effect X-Band Pulse-Repetition Synthetic-Array Pulse Compression Side Lobe Planar Array.
Raytheon Company has got a $12,921,937 modification to an earlier awarded contract to do options for Cooperative Engagement Capability (CEC) for the AN/USG-2B Shipboard System and three planar array antenna assembly systems.
Recently, global optimization algorithms have shown great potential in the solution of planar array synthesis problems, such as genetic algorithm (GA) [2-4], particle swarm optimization [5,6], differential evolution strategy (DES) [7,8], and ant colony optimization (ACO) [9].
A concentric circular array is a non-uniform planar array and there is no symmetry in its geometry, which will increase the difficulty in the synthesis of this kind of array especially when the desired radiation pattern is complex.
However, the approach is no longer adequate for a planar array with tens of complex elements and a platform, as the computation of the coupling matrix is a very heavy burden.
SQI Diagnostics hopes its CustomPlex service, a one stop shopping for custom planar array and multiplexed assay solutions, could bring revenues from customers who have "single-plex" diagnostic tests and who are looking to multiplex this content using the company's multiplexed product development, commercial diagnostic production and SQiDworks and SQiDLITE automated analysers.
Another measure is that the adjacent rows or columns of elements in a planar array are oppositely excited in phase and in orientation [1,10,11].
