Rice Classification Using Three-Step Neural Network Integration Meesri, Sarawut., Amornsamankul, Somkid., Kraipeerapun, Pawalai This paper proposes a three-step neural network integration. In the first step, two neural networks are trained to produce a truth output and a falsity output. The second step uses cascade generalization to improve the results of the first step. A sequence …

Maximizing vertex rescue: investigating the firefighter problem with edge subdivision Chutchawon Weeranukunjit, Chanun Lewchalermvongs The firefighter problem is a game played on a connected graph where a fire breaks out at a vertex. In each round, a firefighter chooses a vertex to protect, and the fire then spreads to all unprotected neighbors of the burning vertex. …

A note on an analogue of Hadamard’s theorem for determining the radii of m-meromorphy Nattapong Bosuwan In this paper, we prove an extension of Hadamard’s classical theorem for determining the radius of mmeromorphyof an analytic function in terms of its Taylor coefficients. Our extension is expressed in terms of Fouriercoefficients with respect to an orthonormal …
