Staggered grid Lagrangian schemes for compressible hydrodynamics involve a choice of how internal energy is advanced in time. The options depend on two ways of defining cell volumes: an indirect one, that guarantees total energy conservation, and a direct one that computes the volume from its definition as a function of the cell vertices. It is shown that the motion of the vertices can be defin...

Concerns about fuel exhaustion, electrical energy shortages, and global warming are growing due to the crisis. Renewable energy-based distributed generators can assist in meeting rising demands. Micro-energy grids have become a research hotspot as crucial interface for connecting power produced by renewable resources-based system. The integration of micro-energy grid technology at load level ha...

To organise in vitro neural networks at the cellular level and study their electrical patterns, we have fabricated 4 x 4 planar microelectrode arrays using conventional photolithography. The electrode sites of these arrays are located inside micro-wells, for confining the neurons, which are connected with neighbouring wells via micro-trenches capable of guiding the outgrowth of neurites. In ord...

DFID Using AMCs to promote green mini-grids in Tanzania ii Executive Summary This annex considers how Advance Market Commitments (AMCs) might be used to promote the development of green mini-grids in Tanzania. It is one of two case studies Vivid Economics has undertaken to complement its report on the economics of AMCs. The second case study concerns the development of micro-Concentrated Solar ...

This paper presents an optimization approach for Micro-cogeneration systems with internal combustion engines integrated into residential grids, addressing power demand failures caused by intermittent renewable energy sources. The proposed method leverages machine learning techniques, control strategies, and grid data to improve system flexibility efficiency in meeting electricity domestic hot w...

While carbon films are highly desirable for supporting specimens for electron microscopy, the difficulty in preparing them prevents their routine use in many laboratories. The usual method employed is to coat the grids with a plastic film which is then coated with carbon in an evaporator, followed by removal of the plastic with a suitable solvent (6). Satisfactorily removing the plastic film wi...
