چکیده
The effect of lateral pressure on the wavelength response characteristics of a fiber Bragg grating embedded in a cylindrical package of silicone rubber has been investigated in this report. Due to high Poisson’s ratio (0.48) and low stiffness of silicone rubber, force applied in one direction will be efficiently transferred to the perpendicular direction also. A wavelength shift of more than 1 nm without considerable pulse broadening and peak splitting has been achieved. The lateral pressure sensitivity is 0.6 nm/N/mm. This value is almost 8 times as high as the lateral pressure sensitivity of bare fiber. The device has got applications in the area of optical sensing and communication.

Long Range Forces from the Cosmological Neutrino Background
The cosmological neutrino background will mediate long range forces between objects. For a background of temperature T, the potential decreases as 1/r 5 for r >> 1/T and as 1/r for r << 1/T. These forces have large spin-dependent components. If the neutrino background is nonrelativistic, the long range forces are enhanced by a factor of the inverse neutrino velocity. These long range forces may...
متن کاملThe Extragalactic Ionizing Background at Low Redshift
We present a measurement of the mean intensity of the hydrogen-ionizing background radiation field at low redshift using 906 Lyα absorption lines in 151 quasar spectra from the archives of the Faint Object Spectrograph (FOS) on the Hubble Space Telescope (HST). Using a maximum likelihood technique and the best estimates possible for each QSO’s Lyman limit flux and systemic redshift, we find J(ν...
متن کامل1 Epic in Orbit Background
We briefly describe the methods used in compiling a set of high galactic latitude background data. The characteristics and limitations of the data which affect their use as a template for analysing extended objects are described. We briefly describe a spectral fitting analysis of the data which reveals a normalisation for the extragalac-tic background of 11.4 keV cm −2 s −1 sr −1 , which implie...

A short outline is given on the application of differential regularization to QCD in the background-field method. The derivation of the propagators in the background gluon field as short-distance expansions is described and the renormalization of the theory is mentioned.
متن کاملVideo Segmentation via Diffusion Bases
Identifying moving objects in a video sequence, which is produced by a static camera, is a fundamental and critical task in many computer-vision applications. A common approach performs background subtraction, which identifies moving objects as the portion of a video frame that differs significantly from a background model. A good background subtraction algorithm has to be robust to changes in ...

The potential of GENIUS as a dark matter detector is discussed. A study was performed to demonstrate the good behaviour of the proposed detector design of naked HPGe-crystals in liquid nitrogen. The expected background components were simulated and are discussed in some detail.With the obtained background GENIUS could cover a large part of the favoured MSSM parameter-space.
