چکیده

As computers and scientific instruments become more complicated and more powerful (Moore’s Law), we can perform astronomical observations never before contemplated. As larger data volumes are acquired, as more complex instruments are designed, and as observatories are placed in distant space locations with constrained downlink capacity, the need for automated, robust image processing tools will increase. We present a robust, optimized algorithm to perform automated processing of array image data obtained with a non-destructive read-out. We present the derivation of the noise effects of this algorithm and compare alternative strategies.

Sources of sub - GZK cosmic rays

We analyze the existing evidence that BL Lacertae objects (BL Lacs) are sources of the highest-energy cosmic rays. We argue that three independent signatures observed in the real data — (1) improvement of correlations with corrections of trajectories for the Galactic magnetic field; (2) connection between γ-ray and UHECR emissions; (3) non-uniform distribution of correlating rays over the sky —...

Possible Discrimination between Gamma Rays and Hadrons using Čerenkov Photon Timing Measurements

Atmospheric Čerenkov Technique is an established methodology to study TeV energy gamma rays. However the challenging problem has always been the poor signal to noise ratio due to the presence of abundant cosmic rays. Several ingenious techniques have been employed to alleviate this problem, most of which are centred around the Čerenkov image characteristics. However there are not many technique...

Physical Investigation of Space, Dosimetry of Space Ionizing Ray Effect (Van Allen belts, Galactic Cosmic Rays and Solar particles) and Plotting Dose Map for Satellite Circular Missions

One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...

Analysis of Non-uniform Sampling Effects in Sigma-Delta Modulated Signals

Ahsfruct-The effects of non-uniform sampling in the EA-modulated DAC are discussed in this paper. The non-uniform sampling of the EA-modulated signals causes in-hand noise in the DAC, which will be compared with the harmonic distortions in switched capacitor circuit and the that due to the signal-dependent nonlinearity in the 1-hit DAC. We describe an error-driven edgeselection ulgorithm that s...

Determining the Hydro-acoustic Characteristics of the Ship Propeller in Uniform and Non-uniform Flow

This research has been carried out to determine the marine propeller hydro-acoustic characteristics by Reynolds-Averaged Navier-Stokes (RANS) solver in both uniform and non-uniform wake flow at different operating conditions Wake flow can cause changes in pressure fluctuation and gas effect on propeller noise spectrum. Noise is generated by the induced trailing vortex wake and induced pressure ...
