  • In this note, we show that the cone property is satisfied for a class of dissipative equations of the form $u_t={\Delta}u+f(x,u,{\nabla}u)$ in a domain ${\Omega}{\subset}{\mathbb{R}}^2$ under the so called exactness condition for the nonlinear term. From this, we see that the global attractor is represented as a Lipshitz graph over a finite dimensional eigenspace.

  • According to the new Singapore Authority Rule(Sn.1/Cir293) which has taken effect from $1^{st}$ July, 2011 at 000hrs, all vessel crossing the Traffic Separation Scheme(TSS) and precautionary areas in Singapore Strait are recommended to display the night signals consisting of 3 all-around green lights in a vertical line. So, this paper presents methods for design of SINGAPORE STRAIT TRANSITION NIGHT SIGNAL.

  • The recent work by the authors (see, Withers, 1999; Withers and McGavin, 2006; Withers and Nadarajah, 2006) provided new expressions for repeated upper tail integrals of the univariate normal density and so also for the general Hermite function. Here we derive new expressions for repeated lower tail integrals of the same. The calculations involve the use of Moran's L-function and the Airy function. In particular, the Hermite functions are expressed in terms of Moran's L-function and vice versa.

  • We introduce a new biharmonic kernel for the upper half plane, and then study the properties of its relevant potentials, such as the convergence in the mean and the boundary behavior. Among other things, we shall see that Fatou's theorem is valid for these potentials, so that the biharmonic Poisson kernel resembles the usual Poisson kernel for the upper half plane.

  • In this paper, we implemented this failure detecting and monitoring system for high-pressure natrium lamps and ballasts. The hall CTs of the local detecting system measure the current flowing into natrium lamps via ballasts and acertain whether the natrium lamps or ballasts are out of order or not. These test data are transmitted to the main monitoring system. So, we can see the status of the natrium lamps or ballasts promptly.
