In this paper, Ultra-Wideband Multi-Input-Multi-Output (UWB-MIMO) antenna with band-notched features is introduced. The band notch of the designed by inserting T-strip into radiating patch to eliminate interference WiMAX applications from 3 4 GHz. To improve isolation and diversity between radiators, radiators are arranged orthogonally decoupling structure added them. proposed has a compact siz...

dN The field scattered by an antenna contains a component that is the short circuit scattered field normalized by the short circuit current, and a second component that ls the radiation field normalized by the transmitting current and multiplied by a factor (1 r). RCS is the magnitude squared of the difference between two terms, one being the square root of a complex "structural" cross section,...

The PANDA experiment at the facility for anti-proton and ion research (FAIR) will study the strong interaction by precision spectroscopy. A detector system with excellent particle identification (PID) is therefore required. Charged hadron identification in the barrel region will be performed by ka compact ring imaging Cherenkov detector based on the DIRC (Detection of Internally Reflected Chere...

Thermostatic radiator valves (TRV) have proved their significant contribution in energy savings for several years. However, at low heat demand conditions, an unstable oscillatory behavior is usually observed and well known for these devices. This closed-loop instability is due to the nonlinear dynamics of the radiator which result in a large time constant and a large gain for the radiator at sm...

Around 1980, Japan’s High Energy Accelerator Research Organization, also known as the KEK laboratory, began developing silica aerogels a Cherenkov radiator. In 1996, high energy physics group at Chiba University, Japan, aerogel research and development in collaborating with KEK. The design of state-of-the-art detectors is enabled by improving transparency. Simultaneously, ultrahigh- ultralow-re...

The Landau-Pomeranchuk-Migdal effect is the suppression of Bethe-Heitler radiation caused by multiple scattering in the target medium. In this paper, the quantum treatment given earlier for finite but homogeneous targets is extended to structured targets. It is shown that radiators composed of separated plates or of a medium with a varying radiation length can exhibit coherence maxima and minim...

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 ...
