High-power Free-Electron Lasers were made possible by advances in superconducting linacs operated in energy-recovery mode. In order to get to very high power levels, say a fraction of a megawatt average power, many technological barriers are yet to be broken. We describe work on CW, high-current and high-brightness electron beams. This will include descriptions of a superconductinglaser-photoca...
This paper is concerned with the employment of an autonomous and intelligent agent within the context of a 3-dimensional virtual environment. As the agent is immersed within the virtual environment, it empowers the 3D world with mechanisms to adjust itself to the specific needs of its user. Therefore, the agent serves as a middle layer between user and the environment. The 3-dimensional environ...
The Human Body Is Electricity Based. Electricity made inside the body cells, using low levels of electric currents at one-millionth of an Ampere –called a micro-current– provides power for the body. Injured cells resist the body's natural micro-current. This causes the natural micro-current to take the path of least resistance around the area of injury rather than through it. This prevents the ...
We give preliminary results on the breakdown and low current limit of volt–ampere characteristics of simple parallel plate non-equilibrium dc discharges at standard (centimetre size) and micro-discharge conditions. Experiments with micro-discharges are reported attempting to establish the maintenance of E/N , pd and j/p2 scalings at small dimensions down to 20μm. It was found that it may not be...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
In this paper we investigate comparative analysis of different antenna parameter (directivity, side lobe level and convergence time ) by using different type of optimizing technique such as Taguchi‟s, PSO, RCGA for synthesis of broad side and end fire linear antenna array in WI-MAX application. On ampere current is provided to each element and radiated power is decreases and radiation intensity...
This paper proposes a low voltage CMOS nano-ampere current reference circuit and presents its performance with circuit simulations in 180-nm technology. The proposed circuit consists of biasvoltage, current-source and offset-voltage sub-circuits with most of MOSFETs operating in subthreshold region. Simulation results show that the circuit generates a stable reference current of 110-nA in suppl...
The properties produced by integral coloured anodic oxide films and sulphuric acid, oxalic acid, maleic acid and different anodizing aluminium alloys -Si, Mg, Fe, Cuare studied. A two stage anodizing procedure was employed. The influence of alloy and solution composition, temperature, concentration, voltage, ampere, time from optimization simplex and anodizing conditions are considered. An oxid...
