this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
An implicit finite volume model is developed to simulate wave interaction with a vertical porous seawall in two-dimensional vertical plane. The algorithm solves the complete Navier–Stokes equations in two steps. First the pressure term in the momentum equations is excluded and the resultant advection–diffusion equations are solved. In the second step the continuity and the momentum equations wi...
It has been shown [1,2] that the electromagnetic quantum vacuum makes a contribution to the inertial mass, mi, in the sense that at least part of the inertial force of opposition to acceleration, or inertia reaction force, springs from the electromagnetic quantum vacuum (see also [3] for an earlier attempt). Specifically, in the previously cited work, the properties of the electromagnetic quant...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
The wind velocity and temperature profiles observed in the middle atmosphere (altitude: 10-100 km) show perturbations resulting from superposition of various atmospheric waves, including atmospheric gravity waves. Atmospheric gravity waves are known to play an important role in determining the general circulation in the middle atmosphere by dynamical stresses caused by gravity wave breaking. In...
Orography is known to influence winter precipitation in Asia and the Indo-Pacific Ocean by mechanically forcing winds, but the dynamics involved in the precipitation response are incompletely understood. This study investigates how two types of orographically forced oscillatory motions alter time-mean winds and precipitation. The quasi-geostrophic omega equation is used together with previous i...
High resolution radiosondes that were launched at Ushuaia (54.8S) during October-December, 1995 are examined. Episodes of high gravity wave activity are found in the lower stratosphere (from 10 km to 24 km). The enhancement of gravity wave activity is ascribed to the conjuction of two factors: gravity wave generation and Doppler-shifting. Two radiosondes with high wave activity cases are examin...
the present research was conducted to explore the effect of employing two language teaching approaches, i.e. schema-based instruction (sbi) and translation-based instruction (tbi), on vocabulary knowledge, structure and reading comprehension ability of forty one female students learning english in grade one senior high school in rivash, kuhsorkh, iran. while sbi focuses on schemata, i.e. words ...
Ocean wave is one of the renewable energy resources that these days various devices are used to extract its energy. Oscillating Water Column (OWC) installed on the shore is one of the wave energy absorption systems which has received attention due to its simple structure. Investigation of the pneumatic power is of great importance in such systems as the conversion of wave energy to pneumatic en...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
