GUIDED PUMP-AS-TURBINE: DESIGN AND DEVELOPMENT FOR PICO-LEVEL ENERGY GENERATION
The Project- “Guided Pump as Turbine” aims to further research in the field of Pico Hydel Projects. This has been accomplished by building a prototype “Pump as Turbine” apparatus consisting of a centrifugal pump running as turbine to generate power. Along with these apparatus the centrifugal pump is converted to guided-pump where stator is appropriately introduced into the system. The purpose of this is to enhance the efficiency of the system. The project holds tremendous benefit by way of providing power/electricity to small communities dwelling in regions having potential for pico-scale hydel power exploitation. The development of the prototype is accomplished under a controlled environment. Head availability and the flow rate are the two measures against which it is optimized. Furthermore, the effect of introducing guide vanes, hitherto unknown, was investigated and analyzed. Analysis was done first on power and efficiency of produced by technology and then on a dimensionless basis to facilitate scaling up/down of PAT capacity for further research. The project has accomplished a detailed analysis of the characteristics of a pump running as a turbine, over a variety of conditions, with and without guide vanes

Signatures of anomalous VVH interactions at a linear collider
We examine, in a model independent way, the sensitivity of a Linear Collider
to the couplings of a light Higgs boson to gauge bosons. Including the
possibility of CP violation, we construct several observables that probe the
different anomalous couplings possible. For an intermediate mass Higgs, a
collider operating at a center of mass energy of 500 GeV and with an integrated
luminosity of 500 fb is shown to be able to constrain the vertex
at the few per cent level, and with even higher sensitivity in certain
directions. However, the lack of sufficient number of observables as well as
contamination from the vertex limits the precision with which the
coupling can be measured.Comment: Typeset in RevTeX4, 16 pages, 12 figures; V2: minor changes in title
