Best Management Practices (BMPs) are implemented in a watershed to reduce the amount of non-point source pollutants transported to water bodies. However, an optimization algorithm is required to choose the efficient type, size, and location of BMPs for application in a watershed for improving the water quality. In this study, the Charged System Search, a well-known and powerful meta-heuristic o...

The paper deals with a set of algorithms including path planning, trajectory planning, and path tracking for a tricycle type wheeled mobile robot. Path planning is carried out with parametric polynomial interpolation using an optimization algorithm based on robot geometric constraints. Trajec-tory characteristics are then derived from the planned geometric path with time varying parameters. A s...

I discuss two techniques that can be used in the investigation of the properties of “colliding” and “non-colliding” anyons.

This paper studies “colliding keys” of RC4 that create the same initial state and hence generate the same pseudo-random byte stream. It is easy to see that RC4 has colliding keys when its key size is very large, but it was unknown whether such key collisions exist for shorter key sizes. We present a new state transition sequence of the key scheduling algorithm for a related key pair of an arbit...

We study an optimization problem given by a discrete inclusion with end point constraints. An approach concerning second-order optimality conditions is proposed.

Introduction: NEAR Shoemaker and HAYABUSA landed on asteroids and Philae of Roset-ta mission and HAYABUSA-2 are going to land on Churyumov-Gerasimenko comet and 1999 JU3 asteroid , respectively, as of writing this abstract. For such missions in the future, we suggest dust monitoring instrument on a CubeSat dispatched to the target body from the main spacecraft. CubeSat is a type of minia-turize...

In this paper, we discovered that RC4 can generate colliding key pairs with various hamming distances, other than those found by Matsui (with hamming distance one), and by Chen and Miyaji (with hamming distance three). We formalized RC4 colliding key pairs into two large patterns, namely, Transitional pattern and Self-Absorbing pattern, according to the behavior during KSA. The colliding key pa...

The colliding pucks simulation is an application originally developed to benchmark the performance of the Time Warp method of parallel discrete event simulation. The application simulates the movements of pucks on a 2-dimensional frictionless surface. All puck collisions and the results of the collisions for a particular simulation run are recorded. This allows a post-processor to determine the...
