Precise and stable operations in micromanipulation microassembly require a high-performance microgripper. To improve the predominant static dynamic characteristics, novel piezoelectric-actuated compliant microgripper is designed, analyzed, tested this paper. The realizes large gripping stroke by integrating bridge mechanism, an L-shaped levered parallelogram mechanism. Optimization technology b...

In this paper, we introduce a new method to realize symmetric functions with reversible circuits. In contrast to earlier methods, our solution deploys a simple and regular cascade structure composed of low-cost gates which enables significant reductions with respect to quantum costs. However, the number of garbage outputs increases slightly. To overcome this, we next propose an optimized design...

A powerful eigenfilter approach is proposed to determine the optimal coefficients of McClellan transformation. It can design arbitrary shape transformation contours to map from 1-D prototypes to 2-D FIR filters very effectively. This paper presents the design methods for 2-D fan filters with general slope and inclination angle, elliptically symmetric filters of arbitrary orientation, circularly...

The present investigation deals with the propagation of waves in the layer of an anisotropic fibre reinforced thermoelastic solid. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitude of displacements and temperature distribution were also obtained. Finally, the numerical solution was carried out for Cobalt material...

We extend the notion of unital as well as unitary polarity from finite projective planes to arbitrary symmetric designs. The existence of unitals in several families of symmetric designs has been proved. It is shown that if a unital in a point-hyperplane design PGd−1(d, q) exists, then d = 2 or 3; in particular, unitals and ovoids are equivalent in case d = 3. Moreover, unitals have been found ...

In this paper, Burr-type XII ̄X synthetic schemes are proposed as an alternative to the classical ̄X synthetic schemes when the assumption of normality fails to hold. First, the basic design of the Burr-type XII ̄X synthetic scheme is developed and its performance investigated using exact formulae. Secondly, the non-side-sensitive and side-sensitive Burr-type XII ̄X synthetic schemes are int...
