Retinal prosthetic devices stimulate retinal nerve cells with electrical signals proportional to the incident light intensities. For a high-resolution retinal prosthesis, it is necessary to reduce the size of the stimulator pixels as much as possible, because the retinal nerve cells are concentrated in a small area of approximately $5\, \hbox{mm} \times 5\, \hbox{mm}$. In this paper, a miniaturized...
This paper presents the evaluation performance of 15kWp hybrid power system based on AC Coupled PV Diesel Hybrid power system in Malaysia. The system consists of 15 kWp of Photovoltaic (PV) array, 11.4 kW of inverter, 36000 AH of total battery capacity, 10kW bi-directional (BD) inverter and 12 kVA of diesel generator (DG). The system provides electricity to one of remote schools in Sabah, East Malaysia...
End-On interferometric measurements of the areal electron density distribution of wire array z-pinches has revealed striking differences in the behaviour of ablation plasmas. A change in wire material from aluminium to tungsten results in a change from a highly collisional structure dominated by shock formations to a much less collisional regime.
OEDIPE is a compact 950 kA 1.2 µs rise time Linear Transformer Driver generator used as a test-bed for the higher current SPHINX machine. Tungsten conical wire array experiments have been performed on this test-bed in order to produce plasma jets relevant to laboratory astrophysics experiments. Initial experiments have demonstrated that jets produced on a microsecond time-scale reach up to 10 cm length...
A new hohlraum configuration for radiation physics/ICF was proposed [B. Jones et al., PRL 104, 125001 (2010)]. Multiple compact (mm-scale) planar wire array (PWA) sources that surround a central hohlraum allow reduced hohlraum surface area and potentially provide a hotter x-ray environment than in a double-ended scheme with cylindrical arrays. The current multiplication technique became possible because...
In most countries the electric power industry has been undergoing through drastic and dramatic changes. The electrical utilities have been structured in separate generation, transmission and distribution segments bringing in a transparency in the utility business. Depending on the market structure of each country, the individual segments have also to compete in liberalized markets.
Recent wire-array Z-pinch experiments performed on the MAGPIE generator at Imperial College are presented at currents up to 1.5 MA. Experiments have been conducted using a variety of array configurations, including radial wire arrays, cylindrical arrays, and coiled arrays.
In a finite-segment p-adic number system one of the difficult problems is concerned with converting Hensel codes back into rational numbers. An algorithm for this conversion is proposed which is based on a sophisticated table look-up procedure.
