This paper describes a novel approach to the design of high selectivity duplexers in microstrip technology for applications in mobile communications systems. The configuration proposed makes use of two single-sided filters (devices characterized by requirements in one passband and one stopband, both of finite extension). Using this class of filters it is possible to obtain high selectivity and ...

and equation 1.1, does it follow that f is a multiplicative character? The problem has recently received some attention. In [2], Choi and Siu proved that the converse is not true for k > 1. One of the arguments given is quite pretty, and proceeds as follows: Let λ be a linear automorphism of Fpk so that λ(1) = 1. If f satisfies 1.1 and 1.2, so does f composed with λ. Now, if f is an injective m...

In this paper, we developed a probability density function (PDF) shape control method for non-linear stochastic systems using hybrid logistic (HLF) as an approximate PDF of the state variable. First, functional relationship between and controller was established based on Fokker–Planck–Kolmogorov (FPK) equation. Then, optimal derivation completed optimization inner product definition Hilbert spa...

A cryptographic pairing evaluates as an element of a finite extension field, and the evaluation itself involves a considerable amount of extension field arithmetic. It is recognised that organising the extension field as a “tower” of subfield extensions has many advantages. Here we consider criteria that apply when choosing the best towering construction, and the associated choice of irreducibl...

The fractional stochastic vibration system is quite different from the traditional one, and its application potential enormous if noise can be deployed correctly connection between order property unlocked. This article uses a modification of well-known van der Pol oscillator with multiplicative additive recycling noises as an example to study stationary response bifurcation. First, based on pri...

In this paper, we propose an extension of the algorithm proposed by Bajard, Imbert and Negre in (Bajar et al., 2006), refered as BIN algorithm. We use binomial residue representation of field elements instead of the Lagrange representation of (Bajar et al., 2006). Specifically, every elements in Fpk is represented by a set of residue modulo fixed binomials. We propose two versions of our algori...

Viscoelasticity and variable mass are common phenomena in Micro-Electro-Mechanical Systems (MEMS), could be described by a fractional derivative damping stochastic process, respectively. To study the dynamic influence cased viscoelasticity mass, stationary response of kind nonlinear systems with variable-mass derivative, is investigated this paper. Firstly, an approximately equivalent system st...
