Radiation dose measurements of radiopharmaceuticals and calibrators at different voltages fluctuations were evaluated. Low high doses technetium, iodine fluorine pharmaceuticals measured in voltages. The results showed that only low could make small insignificant differences.

Ø provide independent control of the magnitude and frequency of the generated output voltages; Ø give sinusoidal input currents with full control of the displacement angle; Ø provide the maximum output to input voltage ratio; Ø satisfy the conflicting requirements of minimum low order harmonics and minimum switching losses, Ø be able to compensate the effects of unbalanced and/or distortions of...

Measurements of the energy resolution and the peak-to-background ratio of a Silicon Drift Detector at several positions and biasing voltages are performed. The origins of events with partial charge collection, which contribute to the background, are identified. A model describing the different mechanisms and the spatial distribution of partial events is developed. By optimizing the biasing volt...

This paper discusses the possibility that there is an enhancement of volume production due to gettering of atomic hydrogen by the caesium deposited on the walls, which reduces the negative ion destruction by associative and non-associative detachment. Such an enhancement would take place for all plasma grid bias voltages. Furthermore at plasma grid bias voltages higher than the plasma potential...

This paper presents a synthesis scheme based on simulated annealing, to minimize power consumption with resources operating at multiple voltages under timing and resource constraints. The scheme considers both scheduling and partitioning simultaneously to reduce power consumption with considering layout issues. Experimental results with a number of DSP benchmarks show that the scheme can achiev...

Models for the calculation of lightning-induced voltages on distribution networks, should be able to take into account the presence of shielding wires and/or neutral conductors and of their relevant groundings. The paper deals with the estimation of the influence of these groundings with particular reference to the grounding electrode model on the calculated values of the lightninginduced volta...

In this paper, we present a new class of charge pump capable of generating voltages 3.75 times greater than the supply in a single clock cycle. It occupies .005 mm in a 0.13μm CMOS process and can operate with a supply voltage between 0.4V and 1.2V, or as low as 0.2V with some pulse-shape distortion. Our charge pump can provide output voltages of up to 3.9V with less than 10nW of standby power ...
