Collocation Assessment between GEO and GSO Satellites
The change in orbit evolution between collocated satellites (X, Y) inside +/-0.09° E/W and +/0.07° N/S cluster, after one of these satellites is placed in an inclined orbit (satellite X) and the effect of this change in the collocation safety inside the cluster window has been studied and evaluated. Several collocation scenarios had been studied in order to adjust the location of both satellite...
متن کاملDoppler Effect in Non-gso Satellite Propagation
Recent technological advances have accelerated a renaissance in usage of non-geostationary (non-GSO) communication satellites in provision of various services domestically and globally. Early ventures into communication satellites have used satellites in low Earth orbits. The main reasons for this mode of operation were that the booster technology was not available to lift satellites into a hig...
متن کاملChiral rings and GSO projection in Orbifolds
The GSO projection in the twisted sector of orbifold background is sometimes subtle and incompatible descriptions are found in literatures. Here, from the equivalence of partition functions in NSR and GS formalisms, we give a simple rule of GSO projection for the chiral rings of string theory in C/Zn, r = 1, 2, 3. Necessary constructions of chiral rings are given by explicit mode analysis. ∗Wor...
متن کاملPerformance of a GSO Brain PET Camera
A high sensitivity, high resolution brain PET scanner has been developed. The scanner comprises 58 rows of 320 4 x 4 x I O mm3 gadolinium orthosilicate (GSO) crystals, coupled to a continuous light guide that is sampled by 288 39-mm photomultiplier tubes in a hexagonal grid. A distortion removal algorithm has been developed to remove position non-linearities and to identify individual crystal r...
متن کاملBFGS-GSO for Global Optimization Problems
To make glowworm swarm optimization (GSO) algorithm solve multi-extremum global optimization more effectively, taking into consideration the disadvantages and some unique advantages of GSO, the paper proposes a hybrid algorithm of Broyden–Fletcher–Goldfarb– Shanno (BFGS) algorithm and GSO, i.e., BFGS-GSO by adding BFGS local optimization operator in it, which can solve the problems effectively ...
