an extended octagonal ring (eor) transducer was designed and developed to measure forces inside the compression chamber of a large square baler in different directions. the transducer was calibrated by applying forces in three directions simultaneously and independently. the sensor revealed excellent linearity along with small cross sensitivities. horizontal and vertical primary sensitivities o...

In the past few years, small scale anisotropy has become a primary focus in the search for source of Ultra-High Energy Cosmic Rays (UHECRs). The Akeno Giant Air Shower Array (AGASA) has reported the presence of clusters of event arrival directions in their highest energy data set. The High Resolution Fly’s Eye (HiRes) has accumulated an exposure in one of its monocular eyes at energies above 10...

We discuss the anisotropic arrival directions of the ultra high energy cosmic rays detected by Auger which I consider one of the biggest discoverie in astrophysics during the last year.

Assuming atmospheric neutrino oscillations with dominant $ transitions , we discuss how subdominant e mixing (within the Chooz reactor bounds) can alter the zenith distributions of neutrino-induced electrons and muons. We isolate two peculiar distortion eeects, one mainly related to e mixing in vacuum and the other to matter oscillations, that may be suu-ciently large to be detected by the Supe...

The expected sensitivity of the water Cerenkov detector array of the southern Auger Observatory site is described by calculations of the energy and zenith angle dependent aperture function (A(E,θ) km sr). The calculations are based, whenever possible, on the forms of the lateral distribution and shower size attenuation that have been empirically determined from previous giant air shower arrays....

We present here results from large zenith-angle observations with the CAT atmospheric Cherenkov imaging telescope, based on data taken on the Crab Nebula and on the blazar Mk501 from 1996 onwards. From Monte Carlo simulations, the threshold energy of the telescope is expected to vary from about 250 GeV at zenith to about 2 TeV at a zenith angle of 60 •. The lower source-fluxes due to the increa...

The lack of a high energy cutoff in the cosmic ray spectrum together with an apparently isotropic distribution of arrival directions for the highest energy events have strongly constrained most models proposed for the generation of these particles. An overview of the theoretical proposals are presented along with their most general signatures. Future experimental tests of the different proposal...
