Optimization and control problems for systems governed by partial differential equations arise in many applications. Experimental studies of such problems go back 100 years [20]. Computational approaches have been applied since the advent of the computer age. Most of the efforts in the latter direction have employed elementary optimization strategies but, more recently, there has been considera...

In this paper we present (quasi-)norm equivalence on a vector-valued function space $L^p_A(l^q)$ and extend the to $p=\infty$ $0<q<\infty$ in scale of Triebel-Lizorkin space, motivated by Fraizer-Jawerth. By applying results, improve multilinear Hormander's multiplier theorem Tomita, that Grafakos-Si, boundedness results for bilinear pseudo-differential operators, given Koezuka-Tomita.

This research investigates the texture influence of masonry walls’ lateral capacity by comparing analytical predictions performed via macro and micro limit analysis. In particular, effect regular quasi-periodic bond types, namely Running, Flemish, English, is investigated. A full factorial dataset involving 81 combinations generated varying geometrical (panel block aspect ratio, type) mechanica...

this paper investigates the dynamics and stability properties of a discrete-time lotka-volterra type system. we first analyze stability of the fixed points and the existence of local bifurcations. our analysis shows the presence of rich variety of local bifurcations, namely, stable fixed points; in which population numbers remain constant, periodic cycles; in which population numbers oscillate amo...

let $g$ be a $p$-group of nilpotency class $k$ with finite exponent $exp(g)$ and let $m=lfloorlog_pk floor$. we show that $exp(m^{(c)}(g))$ divides $exp(g)p^{m(k-1)}$, for all $cgeq1$, where $m^{(c)}(g)$ denotes the c-nilpotent multiplier of $g$. this implies that $exp( m(g))$ divides $exp(g)$, for all finite $p$-groups of class at most $p-1$. moreover, we show that our result is an improvement...

This paper presents a high speed binary floating point multiplier based on Hybrid Method. To improve speed multiplication of mantissa is done using Hybrid method replacing existing multipliers like Carry Save Multiplier, Dadda Multiplier and Modified Booth Multiplier. Hybrid method is a combination of Dadda Multiplier and Modified Radix-8 Booth Multiplier. The design achieves high speed with ma...

In this paper we proposed a three stage pipelined finite-impulse response (FIR) filter, this FIR filter contains multipliers such as Hybrid multiplier, Booth multiplier algorithm and Array multiplier. In general, multiplication process consists of two parts as multiplicand and multiplier. According to the array multiplier, the numbers of partial products (PP) are equal to the number of bits in ...
