Frontispiz: 2D Active Nanobots Based on Soft Nanoarchitectonics Powered by an Ultralow Fuel Concentration

Focus on Materials Nanoarchitectonics.

Fuel-powered artificial muscles.

Artificial muscles and electric motors found in autonomous robots and prosthetic limbs are typically battery-powered, which severely restricts the duration of their performance and can necessitate long inactivity during battery recharge. To help solve these problems, we demonstrated two types of artificial muscles that convert the chemical energy of high-energy-density fuels to mechanical energ...

2D NUMERICAL MODELING OF WAVE TRANSFORMATION ON SOFT MUDDY BEDS

The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...

An FPGA Based Microblaze Soft Core Architecture for 2D- LIFTING

In this paper we propose a technique for software-implementation of an lifting with the goal of getting a customizable lifting DWT-core which can be used as a module in implementing a bigger system irrespective of ones choice of implementation platform. Here we have written the core processor Microblaze is designed in VHDL (VHSIC hardware description language), implemented using XILINX ISE 8.1 ...
