We analyse the factors that led to the turnaround of the Indian Railways from a low performing organisation to a high performing one. Literature on public sector turnaround provides the theoretical underpinnings. Enterprise turnaround is often ascribed to managerial leadership; we found that environmental factors (good luck) contributed in a substantial way to the success of Indian Railways. Th...

We have developed a light scattering technique based on differential measurement and polarization (differential light scattering, DLS) capable in principle of retrieving timing information with picosecond resolution without the need for fast electronics. DLS was applied to sonoluminescence, duplicating known results (sharp turnaround, self-similar collapse); the resolution was limited by intens...

We investigate a spherical collapse model with and without the spatial curvature. We obtain the exact solutions of dynamical quantities such as the ratio of the scale factor to its value at the turnaround epoch (x ≡ a ata ) and the ratio of the overdensity radius to its value at the turnaround time (y ≡ R Rta ) with general cosmological parameters. The exact solutions of the overdensity at the ...

This research paper presents a new contiguous allocation strategy for 3D mesh-connected multicomputers. The proposed strategy maintains a list of maximal free sub-meshes and gives priority to allocating corner and boundary free sub-meshes. The goal of corner and boundary allocation is to decrease the number of leftover free sub-meshes and increase their sizes, which is expected to reduce proces...
