An engineered fluid, called nanofluid, is expected to have better thermal conductivity than conventional working fluids. The superior heat transfer performance and various possible applications promote the analysis of nanofluids in different flow geometries. This paper studies non-Newtonian Burgers’ over a permeable stretching/shrinking surface with source/sink. In current study, we highlight u...

A thin shell finite element approach based on Loop’s subdivision surfaces is proposed, capable of dealing with large deformations and anisotropic growth. To this end, the Kirchhoff-Love theory of thin shells is derived and extended to allow for arbitrary in-plane growth. The simplicity and computational efficiency of the subdivision thin shell elements is outstanding, which is demonstrated on a...

◈ well-known keystream generator ◈ proposed by Coppersmith, Krawczyk and Mansour [Crypto 93] ◈ use two LFSRs A and S. – Let a 0 , a 1 , … denote the sequence generated by A. – Let s 0 , s 1 , … denote the sequence generated by S. ◈ The resultant sequence is a " shrunken " version of the first one. ◈ modified version of Shrinking Generator ◈ proposed by Meier and Staffelbach [Eurocrypt 94] ◈ use...

This article gives a brief overview of the major portable techniques: those based on optical spectroscopy techniques, including near-infrared (NIR), mid-infrared (mid-IR), and Raman spectroscopy; mass spectrometry (MS) systems, high-pressure MS (HPMS), gas chromatography–MS (GC–MS), ion mobility (IMS); elemental such as X-ray fluorescence (XRF) laser-induced breakdown (LIBS); emerging miniaturi...

In this paper we classify the four dimensional gradient shrinking solitons under certain curvature conditions satisfied by all solitons arising from finite time singularities of Ricci flow on compact four manifolds with positive isotropic curvature. As a corollary we generalize a result of Perelman on three dimensional gradient shrinking solitons to dimension four.
