Many activities in construction and demolition projects are generally considered as complicated and unfriendly that may affect surrounding environment and public health. Construction, remodeling, repairing or demotion works of buildings and roads generate large amounts of hazardous and nonhazardous materials. This study highlights the major types o

Experimental investigations using particle image velocimetry technique have been carried out for the evaluation of the differential spoiler setting capabilities in modifying the spanwise wing load and further reduce the wake vortex hazard. The aircraft half model (at high lift configuration) was investigated for two differential spoiler settings. R

Relay channels have been in use for decades as an effective means to tackle some of the challenges facing wireless transmission. Recent studies considered re-employing the relay channel to serve modern wireless systems. Material offered in this book was originally presented by the author as a thesis for the degree of Ph.D. to University College Lon

Dawah is an invitation to someone to participate in some event or to do something. Islamic Dawah is the call to the Truth, to the way of God, the straight path, as well as to the virtuous, dignified and contended life. It invites humanity to comprehend and invoke the ‘Absolute Reality’, a living force behind all realities that derive their stre

In this paper, we study the quantum properties of the three-mode squeezed operator. This operator is constructed from the optical parametric oscillator based on the three concurrent χ(2) nonlinearities. We give a complete treatment for this operator including the symmetric and asymmetric nonlinearity cases. The action of the operator on the number

Globally, the design of the built environment has played a crucial role in preventing design. Increasingly, two school of thoughts namely Defensible Space and New Urbanism are seen as guiding the CPTED agenda for the coming decades. This paper aims to explore the relationship between residential crime and the design of the built environment in rela

The serious impact of the wing tips vortices of a large aircraft is well known. There are many examples of the damage caused to following aircraft caught up in the rotational wake shed from an upstream craft. Topology of the wake vortices downstream of the configuration will largely depends on the span wise load distribution. In order to measure th

In this paper, a single high-order compact flowfield-dependent variation (HOC-FDV) method is developed, valid for twodimensional inviscid compressible as well as incompressible flow problems. The method has third-order accuracy in time and fourth-order accuracy in space. The FDV scheme is used for time discretization and the fourth-order compact Pa

In this paper, a novel high order accurate method, namely high order compact flowfield dependent variation (HOC-FDV) method, has been developed to solve full Navier Stokes equations. The new scheme is a third order accuracy in time and fourth order accuracy in space. The spatial derivatives in the third order accuracy in time, flowfield dependent v
