An efficient and flexible parallel version of a Large-Eddy Simulation (LES) solver has been developed to simulate the compressible tip-flow of a rotor in hover. The solver employs an immersed-boundary technique in conjunction with a curvilinear structured grid and the dynamic model is used to model the subgrid scale (SGS) stress terms. The solver also employs a hybrid implicit-explicit time-dis...

This work describes the computational fluid dynamic (CFD) simulation of flow and pollutant dispersion around a cube. The work attempts to model the characteristics of an atmospheric boundary layer type flow over a building which has a pollutant source at its roof centre. For the flow field, two different numerical schemes for the discretisation of convection have been employed namely the second...

A key goal in road ecology is to determine which species are most vulnerable to the negative effects of roads on population persistence. Theory suggests that species that avoid roads are less likely to be negatively affected by roads than those that do not avoid roads. The goal of this study was to take a step toward testing this prediction by evaluating the behavioral response to roads and tra...

Carbon coatings of thickness down to 2 nm are needed to increase the storage density in magnetic hard disks and reach the 100-Gbitsyinch target. We show that the combination of surface Brillouin scattering, X-ray reflectivity and Raman spectroscopy 2 measurements allow us to measure the mechanical and structural properties of ultra-thin tetrahedral amorphous carbon films. Densities up to 2.8 gy...

Driving a car involves considering it at diierent spatio-temporal scales, and somehow leads to behavior such as the parallel parking maneuver, the three-point turn, free Euclidean driving in a desert, following a road, and translationally passing other vehicles at high speed. In the study of autonomous systems, it is desirable to nd a representation in which such diierent behaviors of a single ...

There are many indications and much practical knowledge about the different tasks which various breeds of dogs are selected for. Correspondingly these different breeds are known to possess different physical and mental abilities. We hypothesized that commonly kept breeds will show differences in their problem solving ability in a detour task around a V-shaped fence, and also, that breed differe...

Medicines constitute a substantial proportion of out-of-pocket (OOP) expenses in Indian households. In order to address this issue, the Government of India launched the Jan Aushadhi (Medicine for the Masses) Scheme (JAS) to provide cheap generic medicines to the patients (http://janaushadhi.gov.in/about_jan_aushadhi.html). These medicines are provided through the Jan Aushadhi stores established...

The recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes a scheme to improve existing on-demand routing protocols by introducing the concept of stable backbone based node scheme in network topol...

The enormous economic loss caused by power quality problems (more than $150 billion per year in USA) makes power quality monitoring an important component in power grid.With highly connected fragile digital equipment and appliances, Smart Grid has more stringent timeliness and reliability requirements on power quality monitoring. In this work, we propose a change-point detection theory-based po...
