We provide a sweep coverage algorithm for routing mobile sensors that communicate with a central data sink. This algorithm improves on its predecessors by reducing the number of unnecessary scans when different points of interest (POIs) have different requirements for the time interval within which they must be scanned (sweep period). Most sweep coverage algorithms seek to minimize the number o...
In this paper, based on the shift splitting of coefficient matrix, a generalized two-sweep (GTSS) method is introduced to solve non-Hermitian positive definite linear systems. Theoretical analysis shows that GTSS convergent unique solution systems under loose restriction iteration parameter. Numerical experiments are reported efficiency method.
As the main noise source in hydrogen fuel cell system, level of centrifugal air compressor greatly affects comfort vehicle, and can be effectively reduced by optimizing trailing edge sweep angle blade. In this paper, computational fluid dynamics model was used to study influence on aerodynamic performance flow characteristics a for vehicle cells. The Ffowcs Williams–Hawkings equation dynamics–b...
Hardwood sawmills traditionally saw logs in a manner that either orients sawlines parallel to the log central axis (straight sawing) or the log surface (allowing for taper). Sweep is characterized as uniform curvature along the entire length of a log. For logs with sweep, lumber yield losses from straight and taper sawing increase with increasing levels of sweep. Curve sawing logs with sweep wi...
-Renewable energy has become the prime source of clean and pure form of energy. With the prevailing energy crisis non-conventional energy has become the solution to it. Harnessing wind energy by several wind turbines is commonly done using various types of rotors. But nowadays Seep twist adaptive rotor blades are used to increase annual energy capture of baseline turbine by 5%-10% without excee...
In the present work, B-ZSM-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. The TiO2- Bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. The uniform membrane intermediate layers with low permeation resistance were...
A series of enantiopure MOP-phosphonite ligands, with tailored steric profiles, have been synthesised and are proven to be very successful in high-yielding, regio- and enantioselective catalytic hydrosilylation reactions of substituted styrenes, affording important chiral secondary alcohols.
