Over many years, there has been great practical interest in how solid bodies interact with and skim on liquid layers. In the present investigation, focus is important role of body mass shape such skimming motions. Considering a thin two-dimensional that impacts obliquely then rebounds shallow inviscid water layer, we develop mathematical model to predict quantitatively duration evolution fluid ...

Abstract Based on the research of space-based multi-target skimming observation, this paper studies observation sequence and orbit path planning low Earth (LEO) targets with goal fuel optimization. Lambert intersection algorithm branch bound algorithm, a two-layer transfer model is established. Through first layer model, optimal target location when are obtained. To obtain global solution, posi...

We present an information good pricing model with persistently heterogeneous consumers and a rising marginal propensity for them to pirate. Three offsetting pricing mechanisms occur: skimming, compressing price changes, and delaying product launch. We identify a novel trade off in piracy’s effect on welfare. We find that piracy quickens sales times and raises welfare in fixed capacity markets, ...

In this study, a biomimetic microfluidic plasma separation device is discussed. The design of the device drew inspiration from in vivo observations of enhanced cell-free layer (CFL) formation downstream of vascular bifurcations. The working principle for the plasma separation was based on the plasma skimming effect in an arteriolar bifurcation, which is modulated by CFL formation. The enhanceme...

video abstraction, video skimming, video summarization The fast evolution of digital video has brought many new applications. Consequently, research and development of new technologies are greatly needed which will lower the costs of video archiving, cataloging and indexing, as well as improve the efficiency and accessibility of stored videos. Among all possible research areas, video abstractio...

In insurance economies with a continuum of agents and adverse selection, it is shown that incentive-constrained Pareto efficient allocations correspond to regulated competitive (or compensated competitive) equilibria in markets with non-linear pricing for options to buy insurance contracts. These options make the incentive constraints self-enforcing. Efficiency is achieved through a “universal ...

In pursuit of the goal to make recorded speech as easy to skim as printed text, a variety of methods and user interfaces have been suggested in the literature, involving time-compressed audio, speech segmentation and recognition, etc. We propose a new user interface, the elastic audio slider, which makes navigation in speech documents similar to video navigation or text scrolling. The approach ...
