Entrepreneurship has long been perceived as a crucial determinant for economic growth. There has been a considerable upsurge in researches trying to determine the main elements driving entrepreneurship and the channel through which entrepreneurship generates economic growth; however, a global consensus has not been reached yet on theoretical, methodological and empirical levels.  The basic prob...

Excitation of unbalanced-Bessel beams by a gradual increase of nonlinearity in a water sample outlines the achievement of the first ever observed quasimonochromatic wave packet that propagates stably for hundreds of Rayleigh lengths in a focusing and dispersive Kerr medium, i.e., in the absence of spectral broadening and conical emission. A modulational instability analysis reveals the key role...

Western region development is fundamental to the sustainable growth of China. The rapid growth in the East and the backwardness in the West vividly demonstrate its unbalanced regional economic structure. The catching-up of the Western region constitutes a major concern for the long-term sustainable development in terms of economic growth as well as in terms of politic stability. Western region ...

A theory for the electromagnetic radiation from unbalanced transmission lines is developed. It is shown that radiation results from the convection current that develops in unbalanced transmission lines where the resistances of the lines are unequal. The process that leads to the generation of the nonlinear convection current in unbalanced transmission lines is explained. It is proved that the c...

phase stand-alone inverter is caused by unbalanced load and a dead time distorts inverter output voltage more unsymmetrically. When the inverter supplies unbalanced load, three phase output voltages include unbalanced odd harmonics but dq-axis voltages at synchronous reference frame have even harmonics with different magnitude each other. In this paper, a new compensation method is proposed to ...

Since implementing the one-child policy in the early 1980s, China has successfully controlled its population growth rate. However, this policy brought together some side effects, one of which is the unbalanced sex ratio. By the year 2000, China had 40.9 million more men than women. The large gender gap has affected both the labor market and the marriage market. We will present a model in which ...

This study extends Baumol’s (1967) two-sector (manufacturing and services) unbalanced growth model to analyze a situation in which, first, services are used for both final consumption and intermediate inputs into manufacturing production, and second, the productivities of the manufacturing and services sectors endogenously evolve. By using this model, we examine the conditions under which the e...

Low voltage microgrids including sensitive loads often face unbalanced load conditions. Therefore, a compensation procedure should be carried out in order to balance and restore sensitive load’s voltage. In this paper, an effective voltage control strategy has been proposed for the autonomous operation of microgrids, under unbalanced load conditions.  The proposed strategy balances single-phase...

Most information retrieval systems based on linguistic approaches use symmetrically and uniformly distributed linguistic term sets to express the weights of queries and the relevance degrees of documents. However, to improve the system-user interaction it seems more adequate to express these linguistic weights and degrees by means of unbalanced linguistic scales, i.e., linguistic term sets with...
