Isogeometric analysis (IGA) has been recently introduced as a viable alternative to the standard, polynomial-based finite element analysis. One of the fundamental performance issues of the isogeometric analysis is the quadrature of individual components of the discretized governing differential equation. The capability of the isogeometric analysis to easily adopt basis functions of high degree ...
Beyond these insights there are further applications and future challenges Sir, Insights into the genetic susceptibility to Crohn's disease (CD) 1 would be incomplete without recognition that the unrivalled success of azathioprine in inducing and maintaining remission in corticoster-oid-dependent CD 2 ought to go hand in hand with a wider application of pharmacogenetic testing 3 so as to optimi...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
the purpose of this study was to examine the status of supervision on departments’ heads at ferdowsi university of mashhad (fum) and realize some applied themes to provide a fit model for supervising departments’ heads in fum. the method was case study under a research category aimed for applied one. using purposive sampling, interviews were conducted with top fum managers, head departments, an...
Mobile radio communication systems are affected by the frequency and time selectivity of radio channel due to multipath propagation and Doppler shifts. In an Orthogonal Frequency Division Multiplexing (OFDM) based Code Division Multiple Access (CDMA) system, the spreading schemes will suffer loss of orthogonality between codewords of different users. In this thesis, basic system model of severa...
Mesoscale atmospheric models currently rely on an integrated land-surface model to provide fluxes of heat, momentum, and moisture from the land surface to the atmosphere. While improvements have been made by tuning land-surface models for a variety of test cases, current models are limited to vertical transport in a shallow soil column. They are thus unable to capture lateral transport of soil ...
Reflection occurs at an air–material interface. The development of antireflection schemes, which aims to cancel such reflection, is important for a wide variety of applications including solar cells and photodetectors. Recently, it has been demonstrated that a periodic array of resonant subwavelength objects placed at an air–material interface can significantly reduce reflection that otherwise ...
The age of air has recently emerged as a diagnostic of atmospheric transport unaffected by chemical parameterizations, and the features in the age distributions computed in models have been interpreted in terms of the models’ large-scale circulation field. This study shows, however, that in addition to the simulated large-scale circulation, three-dimensional age calculations can also be affecte...
Weather Research and Forecasting (WRF) model predictions using different boundary layer schemes and horizontal grid spacings were compared with observational and numerical large-eddy simulation data for conditions corresponding to a dry atmospheric convective boundary layer (CBL) over the southern Great Plains (SGP). The first studied case exhibited a dryline passage during the simulation windo...
