An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...

TORCH is a large-area time-of-flight (ToF) detector, proposed for the Upgrade-II of LHCb experiment. It will provide charged hadron identification over 2–20 GeV/c momentum range, given 9.5 m flight distance from LHC interaction point. To achieve this level performance, 15 ps timing resolution per track required. A prototype module having 1250×660×10 mm3 fused-silica radiator plate and equipped ...

Saat ini banyak kalangan yang memiliki kendaraan impian harganya terjangkau dengan kemampuan keuangan mereka. Namun masyarakat tidak mengetahui cara mengantisipasi dan mencegah secara dini kerusakan dari mobil diakibatkan berfungsinya sistem radiator pendingin mesin. Dibuat memonitor suhu air normal sesuai kerja disyaratkan pabrikan mengatasi overtemp mendadak dapat diatasi mobil. Sistem akan m...

CF4 is used as a Cherenkov gas radiator in one of the Ring Imaging Cherenkov detectors at the LHCb experiment at the CERN Large Hadron Collider. CF4 is well known to have a high scintillation photon yield in the near and far VUV, UV and in the visible wavelength range. A large flux of scintillation photons in our photon detection acceptance between 200 and 800 nm could compromise the particle i...

Modern wireless communications systems require improvement in capacity and data transmission speed. Adaptive array antennas separate spatially a desired wave from interference waves by controlling their radiation or beam pattern directivity. A digital beamforming (DBF) array performs adaptive beamforming by digital signal processing. However, the circuit scale, number of RF channels and power c...

Anderson, et al. have recently reported the discovery of an apparent anomalous, weak, long-range acceleration in the Pioneer 10/11 and Ulysses spacecraft. I believe that this result can be explained by non-isotropic radiative cooling of the spacecraft electronics through passive radiators on the spacecraft surface. These radiators are preferentially placed on the anti-solar side of the spacecra...

this: Light from a lamp of known spectral distribution is modified by rotatory dispersion in a system of quartz plates and nicol prisms in such a way that by rotating one of the nicols the light emerging from it can be made to assume the spectral distribution of a Planckian radiator at any desired temperatrue between 4000 and 7000° K. Such a system is, in effect, a selective light filter of adj...

Radiator arrays with Dynamic Polarization Control (DPC) and 2D beam steering enable polarization matching to the receiver antenna regardless of its polarization, orientation, and location. A fully integrated 122.9 GHz 2x2 DPC multi-port driven phased array radiates all linear polarizations (0°-180° polarization angles) with axial ratios above 14 dB, and controls the axial ratio from 1.2 dB (cir...

A Transition Radiation Detector to identify electrons at 90% ef-ciency with a rejection factor against pions of 10 3 on an area of 2:85 2:85 m 2 has been constructed for the NOMAD experiment. Each of its 9 modules includes a 315 plastic foil radiator and a detector plane of 176 vertical straw tubes lled with a xenon-methane gas mixture. Details of the design, construction and operation of the d...

ISSN 2277 – 5056 | © 2012 Bonfring Abstract--General opinion for the cause of overheating in the engine is scarcity of water in the radiator which causes the engine to seize. Normally refilling the radiators would solve the problem but we have several proven cases where engines still seize due to loosening of belts. Though the current technology allows detection of engine temperature, there is ...
