This paper aims to study some of the factors that influence the sectoral diffusion of innovation. The final objective is to arrive at a model of innovation diffusion in order to analyse how different economic policies can help to promote it. In the first place, an exploratory analysis is carried out in which some new statistics such as the sectoral autocorrelation coefficient are used. Secondly...

Compact shorted 1350 Sectoral microstrip antenna derived from 2700 Sectoral microstrip antenna is proposed. On thicker air substrate (h > 0. 1?0) it yields bandwidth of more than 350 MHz (35%). To increase the bandwidth, its rectangular slot cut variation is proposed. The slot reduces the resonance frequency of higher order TM1/4,1 mode of the shorted patch and along with fundamental TM1/4,0 mo...

In this paper, by using the sequence of adjointable operators from pro-C*-algebra $ mathcal{A} $ into a Hilbert $ mathcal{A} $-module $ E $. We introduce frames with bounds in pro-C*-algebra $ mathcal{A} $. New frames in Hilbert modules over pro-C*-algebras are called standard $ ast $-frames of multipliers. Meanwhile, we study several useful properties of standard $ ast $-frames in Hilbert modu...
