Rational Solutions of the Sasano System of Type
In this paper, we completely classify the rational solutions of the Sasano
system of type , which is given by the coupled Painlev\'e III
system. This system of differential equations has the affine Weyl group
symmetry of type
Isomonodromic deformatiion with an irregular singularity and hyperelliptic curve
In this paper, we extend the result of Kitaev and Korotkin to the case where
a monodromy-preserving deformation has an irregular singularity. For the
monodromy-preserving deformation, we obtain the -function whose
deformation parameters are the positions of regular singularities and the
parameter of an irregular singularity. Furthermore, the -function is
expressed by the hyperelliptic function moving the argument \z and
the period \B, where and the positions of regular singularities move
and \B, respectively.Comment: 23 pages, 2 figure
Dry deposition of SO2 over Dry Dipterocarp Forest, Thailand
The aerodynamic gradient method was applied to estimate dry deposition flux of SO2 over dry deciduous forest in Nakorn Ratchasima province, Thailand. The meteorological parameters and concentrations of SO2 were measured in real time for one year on the experimental tower at 36 and 27 m high. The flux observed in the wet season were found two times higher than the value observed in the dry seasons, i.e. 20±7.58 and 10±11.05 ng m-2 s-1, respectively. The leaf area index and the ambient humidity were believed to assert the rate of SO2 deposition. The average friction velocities were estimated to be 0.26±0.02 and 0.48±0.06 m s–¹, for the dry and the wet season, respectively. The friction velocity was very much depended on the surface roughness of the forest canopy. The Vd of SO2 evaluated by the aerodynamic gradient was compared with Vd calculated by the resistance model. It was found that the observed Vd was in close proximity with the model prediction in daytime in all conditions, i.e. wet, dry and annual average. The annual average Vd determined by the Aerodynamic gradient was 0.43±0.06 cm s-1
