This paper proposes a nonlinear controller to extend the Zwidth of a haptic device. A time-domain passivity analysis of the Z-width diagram leads to the new haptic controller, which employs acceleration feedback. The passivity condition for one degree of freedom (1DOF) haptic interaction with a virtual wall via the proposed controller is derived using passivity theory in the frequency domain. T...

Abstract – This document gives you a brief idea of the Design and simulation of DC/DC Boost converter operating in continuous conduction mode using pulse width modulation based sliding mode controller. The performance and properties of sliding mode controller is compared with Proportional Integral Derivative (PID) controller and Proportional Integral (PI) controller. Simulation results shows th...

Koblitz curves have been a nice subject of consideration for both theoretical and practical interests. The window τ -adic algorithm of Solinas (window τNAF) is the most powerful method for computing point multiplication for Koblitz curves. Precomputation plays an important role in improving the performance of point multiplication. In this paper, the concept of optimal pre-computation for window...

Hui-style architecture is a mature architectural school in the late period of ancient Chinese society with distinct regional cultural characteristics. Especially as most direct carrier Huizhou people’s living culture, witness society, history, and culture. However, continuous development residents gradually put forward higher requirements for environment. In this paper, indoor light environment...

The side channel attack (SCA) is a serious attack on wearable devices that have scarce computational resources. Cryptographic algorithms on them should be efficient using small memory — we have to make efforts to optimize the trade-off between efficiency and memory. In this paper we present efficient SCA-resistant scalar multiplications based on window method. Möller proposed an SPA-resistant w...

The stability and performance of nanoscale junctions are closely related to the local effective temperature. The local effective temperature is mainly caused by the competition between heating and cooling processes in inelastic electron-phonon scat- tering. Local cooling occurs when the rate of energy in cooling exceeds that in heating. Previous research has been done using either specific pote...

In packet switched optical network, packet header extraction and processing in alloptical domain is a challenging task. In this paper we propose a new all-optical header extraction scheme based on the versatile all-optical ultrafast symmetric Mach-Zehnder (SMZ) switch and pulse position modulation (PPM) for 80 Gb/s data rate. In SMZ switches, the residual power residing outside the switching wi...
