ns-3 is a recently released next generation simulator intended as a replacement of the popular ns-2. It enables a highly rich set of features and is expected to become the first choice of the scientific community soon. ns-3 is in its evolution phase and work at different fronts is still ongoing. With the recent emergence of broadband wireless networks, simulation support for such networks, espe...

SNP provides a high-level abstraction for secure end-toend network communications. It supports both stream and datagram semantics with security guarantees (e.g., data origin authenticity, data integrity and data confidentiality). It is designed to resemble the Berkeley sockets interface so that security can be easily retrofitted into existing socket programs with only minor modifications. SNP i...

Based on our previous modi…ed log-wake law in turbulent pipe ‡ows, we invent two compound similarity numbers (Y; U), where Y is a combination of the inner variable y + and outer variable , and U is the pure e¤ect of the wall. The two similarity numbers can well collapse mean velocity pro…le data with di¤erent moderate and large Reynolds numbers into a single universal pro…le. We then propose an...

Superhydrophobic surfaces (SHSs) can reduce the friction drag in turbulent flows. In laminar regime, it has been shown that trace amounts of surfactant negate this reduction, at times rendering these no better than solid walls (Peaudecerf et al., Proc. Natl. Acad. Sci. USA 114(28), 7254-9, 2017). However, effects on drag-reducing properties SHSs have not yet studied under flow conditions, where...

We report our experimental finding that there exists an oscillation of magnetic anisotropy with varying Cr sublayer thickness along the direction normal to the easy axis in Fe/Cr/Fe trilayers, where the easy axis is induced along a certain direction in the film plane by applying an external field during film deposition. Interestingly enough, the squareness of the hysteresis loop measured along ...

The mammalian hippocampus is critical for spatial information processing and episodic memory. Its primary output cells, CA1 pyramidal cells (CA1 PCs), vary in genetics, morphology, connectivity, and electrophysiological properties. It is therefore possible that distinct CA1 PC subpopulations encode different features of the environment and differentially contribute to learning. To test this hyp...

Single-phase turbulent pipe flows are analysed utilizing a new theory presented in parallel paper. Arguably this implies improvements matching modelling results with experimental observations: To illustrate, unique for these computations is that 1st law balance agreement between simulations and corresponding experiments achieved, while resolving the time-averaged fluid flow velocity (including ...

The explosive viscous liquid becomes inject to warhead by discharge system. The injection device is consisted of a piston to move down and leads the viscous fluid through the cylindrical pipe towards the end of the duct. Then the viscous fluid leads into a convergent path that will be injected to the warhead or other injection equipment. In this project, the path of viscous fluid flow is divide...

the paper numerically presents laminar forced convection of a nanofluid flowing in a duct at microscale. results were compared with both analytical and experimental data and observed good concordance with previous studies available in the literature. influences of brinkman and reynolds number on thermal and hydrodynamic indexes have been investigated. for a given nanofluid, no change in efficie...

The interaction between a turbulent boundary layer flow and compliant surfaces is investigated experimentally. Three viscoelastic coatings with different material stiffnesses are used to identify the general surface response conditions. For softest coating, global force measurements show two obvious regimes of an indicated transition at $U_b/C_t\sim 3.5$ , where $U_b$ bulk velocity $C_t$ coatin...
