Due to the tremendous development in field of wireless communication and its use several fields, whether military or commercial was proposed. A novel tapered slot Vivaldi antenna is designed simulated at double band frequency (Ku-band) using computer simulation technology (CST) software 2020. The dimensions are 2.3 × 1 0.4 mm<sup>3</sup> with a microstrip feed 0.5 mm. proposed impro...

A wideband feed network for a Vivaldi antenna array is presented. limitation of current arrays the bandwidth either or element. The proposed consists four antennas fed with an improved to extend useable array. coplanar waveguide-to-slotline-to-microstrip line transitions. has single waveguide input and microstrip output ports. achieved uniform amplitude phase balance impedance 160% from 1 GHz 9...

Recent reports have shown that bilirubin can be esterified in vivo to form a variety of acyl glycosides (Kuenzle, 1970; Heirwegh, Van Hees, Leroy, Van Roy & Jansen, 1970). The question as to whether these conjugates are present in bile as monoconjugates as well as diconjugates remains in doubt. Indirect evidence for the existence of bilirubin monoglucuronide, based on the estimation of the mola...

We present a new network coordinate system, Charm, embedding round-trip time latencies into a Euclidean space. Charm is based on a particle system model with two spatial force interactions: attraction and repulsion. The update algorithm (Charming) that Charm uses is simple and lightweight: At each latency sample, the algorithm either “attracts” the communicating nodes to each other or “repels” ...

A synoptic, hydrographic data set comprising 32 full depth CTD casts and 2500 CTD/SeaSoar profiles to 500 m is used to describe the θ/S properties and circulation of Central Water east of the mid-Atlantic Ridge and between 39°N and 54°N. Eastward transport of 20 x 10 m s in the North Atlantic Current turns entirely northwards to the west of 54°N, 20°W. This transport consists in the upper layer...

La Suonata a 4 al Santo Sepolcro RV 130 e la Sinfonia 169, due composizioni gemelle risalenti con ogni probabilità agli anni Trenta del Settecento, occupano un posto singolare nella produzione strumentale di Antonio Vivaldi. L’indicazione titolo «al Sepolcro» non lascia dubbi sul fatto che le partiture siano connesse Passione Cristo dunque state composte per settimana Pasqua; restano tuttavia p...
