Nematic-isotropic interfaces exhibit novel dynamics due to anchoring of the liquid crystal molecules on the interface. The objective of this study is to demonstrate the consequences of such dynamics in the flow field created by an elongated nematic drop retracting in an isotropic matrix. This is accomplished by two-dimensional flow simulations using a diffuse-interface model. By exploring the c...

High-power electronic devices with multiple heat sources often require temperature uniformity and to operate within their functional range for optimal performance. Micro-channel cooling could satisfy the dissipation requirements, but it may cause non-uniformity. In this paper, simulations are performed different geometric parameters of channel position source. The results show that a flattened ...

Spontaneous motion of liquid droplets can occur on hydrophobic, micro-structured, solid surfaces comprising a structural gradient. In this study, we examine such experimentally and explain our observations by invoking variable droplet–surface interactions (both actuation resistance forces) arising from the The oscillatory droplet constitutes an integral aspect behaviour is incorporated into ove...

We exploit large accelerations associated with surface acoustic waves to drive an extraordinary fluid jetting phenomena. Laterally focusing the acoustic energy to a small region beneath a drop placed on the surface causes rapid interfacial destabilization. Above a critical Weber number We, an elongated jet forms for drops with dimensions greater than the fluid sound wavelength. Further increase...

We analyze the regret, measured in terms of log loss, of the maximum likelihood (ML) sequential prediction strategy. This “follow the leader” strategy also defines one of the main versions of Minimum Description Length model selection. We proved in prior work for single parameter exponential family models that (a) in the misspecified case, the redundancy of follow-the-leader is not 1 2 log n+O(...

Fermi coordinates (FC) are supposed to be the natural extension of Cartesian coordinates for an arbitrary moving observer in curved space-time. Since their construction cannot be done on the whole space and even not in the whole past of the observer we examine which construction principles are responsible for this effect and how they may be modified. One proposal for a modification is made and ...

the upper cretaceous ganj complex, a part of the jazmurian ophiolitic belt, is located on the western boundary of jazmurian depression and separated from kahnuj ophiolitic complex by north-south trending jiroft fault. the complex consists of lava flows, pillow lavas, acidic plutonic and sedimentary rocks which are intruded by northwest-southeast trending dykes. it does not resemble a classical ...
