Preliminary study of effects of winglets on wing flutter [PDF]

open access: yes
Some experimental flutter results are presented over a Mach number range from about 0.70 to 0.95 for a simple, swept, tapered, flat-plate wing model having a planform representative of subsonic transport airplanes and for the same wing model equipped ...

Fireballs Loading and the Blast Wave Model of Gamma Ray Bursts

open access: yes, 1998
A simple function for the spectral power $P(\epsilon,t) \equiv \nu L(\nu) $ is proposed to model, with 9 parameters, the spectral and temporal evolution of the observed nonthermal synchrotron power flux from GRBs in the blast wave model. Here $\epsilon =

On the Interpretation of Energy as the Rate of Quantum Computation

open access: yes, 2005
Over the last few decades, developments in the physical limits of computing and quantum computing have increasingly taught us that it can be helpful to think about physics itself in computational terms.

Trophic model of the coastal fisheries ecosystem of the southwest coast of India [PDF]

open access: yes
The Ecopath approach and software were used to construct a trophic model of the coastal fisheries ecosystem of the southwest (SW) coast of India. The model consisted of 11 ecological groups and used estimated landings from all areas along the southwest ...

Swept areas and collision detection with application to autonomous vehicles

open access: yes, 2005
This thesis presents an algorithm for collision detection for an autonomous articulated vehicle following pregenerated paths in a mining environment. Two types of vehicles are studied. The tricycle vehicle and the articulated vehicle. The characteristics of the mine is presented. A way of using these characteristics is studied.

Breaking Kelvin: Circulation conservation and vortex breakup in MHD at low Magnetic Prandtl Number

open access: yes, 2018
In this paper we examine the role of weak magnetic fields in breaking Kelvin's circulation theorem and in vortex breakup in two-dimensional magnetohydrodynamics for the physically important case of a low magnetic Prandtl number (low $Pm$) fluid.
