We discuss the use of a flat-plane slider for a surface acoustic wave (SAW) motor. For stable driving, the SAW motor requires a silicon slider with many microprojections on its surface. Previously, sliders with no projections on the flat-plane surface could not provide stable drive because of contact electrification occurring due to the low electrical conductivity of the lithium niobate stator....

This paper describes BarterRoam: a new novel mobile and wireless roaming settlement model and clearance methodology, based on the concept of sharing and bartering excess capacities for usage in Visiting Wireless Internet Service Provider (WISP) coverage areas with Home WISP. The methodology is not limited to WISPs; it is applicable to virtual WISPs and any Value-Added Services in the mobile and...

BACKGROUND AND AIM OF THE STUDY The finite element method (FEM) has frequently been used to investigate the behavior of the aortic valve, but studies on the performance and behavior of free-hand autologous pericardial aortic valves reconstructed using specially designed valve molds have not been performed. The study aim was to demonstrate the effectiveness of a three-dimensional (3-D) cusp of t...

A rectangular rod is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of rectangular rod on developing vortex shedding downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary laye...

dually flat finsler metrics form a special and valuable class of finsler metrics in finsler information geometry,which play a very important role in studying flat finsler information structure. in this paper, we prove that everylocally dually flat generalized randers metric with isotropic s-curvature is locally minkowskian.

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

We construct arbitrarily sparse locally-jammed packings of nonoverlapping congruent disks in various finite area regions — in particular, we give constructions for the square, hexagon, and for certain flat tori.

This paper presents the results of the analysis of 56,000 flat grids in a form suitable for minimum weight design.

Flat rate regime is held responsible for this state of affairs and a shift to universal metering is being pushed as remedy. However, metering can work only by creating power retailing entrepreneurs as is being tried out in Orissa. Flat tariff regime can also serve the purpose, provided it is tied to effective supply policies. Judicious rationing and reasonable tariff are essential components of...
