The JEM-EUSO telescope will be, after calibration, a very accurate instrument which yields the number of received photons from the number of measured photo-electrons. The project is in phase A (demonstration of the concept) including already operating prototype instruments, i.e. many parts of the instrument have been constructed and tested. Calibration is a crucial part of the instrument and its use...
The effective use of parallel resources is a central topic for high performance computing developers. Another key challenge is the elaboration of smart systems, in which the final user does not need to define the method to distribute the loads in a cluster. In this work, a methodology is proposed to enable the load balance in an automatized and non-intrusive way. A proposal for implementation and...
Long time series of acoustic sounding data present the opportunity to examine vertical distribution and behavior of zooplankton and other organisms. In this paper, we describe a small, inexpensive, single frequency (200 kHz), upward-looking water column profiler that is mounted as part of the VENUS cabled observatory in Saanich Inlet, British Columbia, Canada, and introduce the concept of depth-time...
In this paper, we present the full polarimetric calibration of GB-SAR system with a thin wire whose orientation angle is 0 degree, 45 degree and 90 degree. At first we measured 0 degree, 45 degree and 90 degree inclined thin wire in order to derive calibration parameters. We also measured 30 degree and 60 degree wire in order to confirm this calibration method works well or not by using the estimated...
In this paper, the first detection result of coherent scatterers (CSs) in forest environment is addressed. As a scatterer associated with CS, the dihedral structure consists of the tree-trunk like a vertical cylinder and the ground surface is assumed. The potential of CSs as being the phase stable scatterers as permanent scatterers will be also demonstrated with P-&L-band Pol-InSAR datasets acquired...
The Japanese microwave remote sensing satellite ALOS/PALSAR was launched successfully in January 2006. We are carrying out polarimetric calibration of the PALSAR sensor, which has the full-polarimetric function of L-band SAR. We set corner reflectors in Ulaanbaatar in May and August 2006, and the acquired data was used to confirm the polarimetric calibration coefficients, which will be used for the...
