Small-Reservoir Electrostatics

Remotely sensed small reservoir monitoring

A new ‘growing’ maximum likelihood classification algorithm for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region, Ghana. The delineation algorithm is able to find the land-water boundary from SAR imagery for different weather and environmental conditions. As such, the algorithm allows for remote sensed operationa...

Physical Electrostatics of Small Field Emitter Arrays/clusters

This paper aims to improve qualitative understanding of electrostatic influences on apex field enhancement factors (AFEFs) for small field emitter arrays/clusters. Using the "floating sphere at emitter-plate potential" (FSEPP) model, it re-examines the electrostatics and mathematics of three simple systems of identical post-like emitters. For the isolated emitter, various approaches are noted. ...

Small mammals – natural reservoir of pathogenic leptospires

A total of 429 specimens belonging to 9 species of small mammals, trapped in various areas of the Czech Republic during the year 2001, were examined for antibodies against leptospires. Antibodies were found in all localities under study in 50 specimens, i.e., 11.6%, belonging to 5 species. Antibodies were most often , i.e., in 42% of positives, found in Microtus arvalis. In Apodemus spp. and Cl...

Dynamics of a small system coupled to a reservoir : reservoir fluctuations and self-reaction

Electrostatics of nanowire transistors

S The electrostatics of nanowire transistors are studied by solving the Poisson equation self-consistently with the equilibrium carrier statistics of the nanowire. For a one-dimensional, intrinsic nanowire channel, charge transfer from the metal contacts is important. We examine how the charge transfer depends on the insulator and the metal/semiconductor Schottky barrier height. We also show th...
