The effective management of technology and new product development in a high technology small to medium enterprise associated with a large corporation with specific reference to the development of solar photovoltaic water pumps is investigated in this study. Innovative product and the development thereof have already become this century's battleground. The availability of information to all and...

To satisfy the demand for more compact medium-voltage motor drive systems, it is desirable to increase frequency of cascaded H-bridge inverters used in high-speed systems. However, asynchronous pulse width modulation (PWM) as output increases, command voltage and triangular wave carrier frequencies get closer, making impossible accurately voltage. This manifest itself increased current harmonic...

I adopt the distribution dynamics framework to study labor productivity convergence, in the period 1980-1995, among 28 developed and developing countries, in different manufacturing sub-sectors, identified, as according their technological content into Resource Based, Low Technology, Medium Technology and High Technology. I find that, exception made for High Technology and Manufacturing as a wh...

In this paper we utilize the main findings from the recent literature to set the economic foundation for the existence of money, its modern interpretation as “memory” (Chokerlakota 1998) and how the Blockchain technology has empowered crypto currencies to perform this role in the information age.  To locate the issue in a historical perspective and in line with this strand of thought, we consid...

the aim of the present study was to investigate the effect of quenching and tempering temperatures on themicrostructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistantsteel. in addition, the dominant wear mechanisms were studied. for this purpose, austenitizing and temperingtemperatures were selected in the ranges of 900- 1000 °c and 300- 500 °c...

Advances in information technology have simplified many processes in our lives. However, in many cases trust issues arise when new technology is introduced, and voting is one prominent example. To increase voters’ trust, current e-voting systems provide paper audit trails (PATs) which enable automatic tally and/or manual audit of the election result. PATs may contain only the encrypted vote or ...

We study the noise activated dynamics of a model excitable system that consists of a subcritical Hopf oscillator with a time delayed nonlinear feedback. The coherence of the noise driven pulses of the system exhibits a novel double peaked structure as a function of the noise amplitude. The two peaks correspond to separate optimal noise levels for excitation of single spikes and multiple spikes ...
