Non-human animals and human children can make use of the geometric shape of an environment for spatial reorientation and in some circumstances reliance on purely geometric information (metric properties of surfaces and sense) can overcome the use of local featural cues. Little is known as to whether the use of geometric information is in some way reliant on past experience or, as would likely b...

Analytical models are presented for conduction shape factors for three-dimensional regions formed between an isothermal, arbitrarily-shaped body and its concentric, arbitrarily-shaped surrounding enclosure. The model is based on the exact solution for the concentric spheres and two methods are developed to predict the effective gap spacing. The models are validated using existing numerical data...

The study of rhomboid-shaped fully packed loop configurations (RFPLs) is inspired by the work of Fischer and Nadeau on triangular fully packed loop configurations (TFPLs). By using the same techniques as they did some nice combinatorics for RFPLs arise. To each RFPL and to each oriented RFPL a quadruple of binary words (α, β; γ, δ) – its so-called boundary – is assigned. There are necessary con...

The dynamics of a water jet on a flat free surface are investigated using a nanosecond pulsed laser for creating an oscillating bubble with different depths beneath the free surface. A thin jet is shown to deform a crater surface resulted from surface depression and cause a circular ring-shaped crater on the connection surface between the crater of surface depression and the thin jet. The colla...

In present study, a 2D rectangular enclosure was considered as latent thermal energy storage (LTES) system. Lauric acid used PCM material. The aim of this study to use fins enhance melting process PCM. Position and shape double were investigating parameters. At first stage three different positions for shape. Results indicated that amongst aforementioned cases, best results achieved when locate...

We consider the Gamma limit of the Abelian Chern-Simons-Higgs energy
