the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...

A new modification of Electromagnetism-like (EM) algorithm which incorporating the Record-to-Record Travel (RRT) local search algorithm; namely MEMR has been developed to solve the problem of Inverse Kinematics (IK) for a four Degree-of-Freedom (DOF) manipulator. The proposed method is able to generate multiple robot configurations for the IK test performed at different end effect or positions....

This paper deals with inverse scattering techniques based on genetic algorithms (GAs), and is devoted to microwave imaging and microwave nondestructive testing and evaluation (NDT/NDE). In the framework of near-field spatial-domain algorithms, a brief overview of current trends and future developments of the research work is given. Numerical results of selected simulations, modeling realistic g...

We provide a compact 200 line MATLAB code demonstrating how topology optimization (TopOpt) as an inverse design tool may be used in photonics, targeting the of two-dimensional dielectric metalenses and metallic reflector examples. The physics model is solved using finite element method, utilizes MATLAB’s fmincon algorithm to solve problem. In addition presenting itself, we briefly discuss numbe...

Abstract The development of information technology urgently requires ultrafast, ultra-low energy consumption and ultra-high-capacity data computing abilities. Traditional method electronic chips is limited by the bottleneck Moore’s Law. All-optical photonic provides a promising way to realize such high-performance Until now, it still huge challenge all-optical four arithmetic operations at same...

Fingerprint image segmentation is one key step in Automatic Fingerprint Identification System (AFIS), and how to do it faster, more accurately and more effectively is important for AFIS. This paper introduces the Markov Chain Monte Carlo (MCMC) method and the Genetic Algorithm (GA) into fingerprint image segmentation and brings forward a fingerprint image segmentation method based on Markov Cha...
