This paper studies the incidence relation between the points and quadrics in the projective space of a symplectic vector space over a field of even order. The 2-rank of the incidence matrix is determined. This is achieved by viewing the code generated by incidence vectors as a module for the symplectic group and applying the 2-modular representation theory of this group. The radical series of t...

Faculty of Symbiotic Systems Science, Fukushima University, Fukushima City, 960-1296, Japan This paper focuses on efficiency of simulation-based optimization for container terminal operation system. Firstly, the discrete-event simulation model of multimodal operation system on container terminal was presented with the queuing network, for which the mathematical optimization model of resource al...

This paper addresses scheduling problems on the material handling operation at marine container-yard terminals. The layout, removal order and removal distination of containers are simultaneously optimized in order to reduce the waiting time for a vessel. The schedule of container-movements is derived by autonomous learning method based on a new learning model considering container-groups and co...

(The main idea: The compression used for stegotext detection. It is known that an embedding message breaks statistical structure of the container, increasing its entropy. Consequently, the full container will compress worse than empty. Let us consider the example: A, B empty and full container respectively. Table 1: Container size before and after compression container.. container size before c...

An approach for the simulation of explosions of ‘‘energetic devices’’ is described. In this context, an energetic device is a metal container filled with a high explosive (HE). Examples include bombs, mines, rocket motors or containers used in storage and transport of HE material. Explosions may occur due to detonation or deflagration of the HE material, with initiation resulting from either me...
