Full text link32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this study, we present light curve analysis of a southern contact binary SY lior. Photometric parameters of the system and its components are derived using the Wilson and Devinney code based on the data taken from the SuperWASP public data archive. Photometric solutions indicate that SY Hai is a marginal contact binary system with a mass ratio of q = 1.59 and a contact degree of f = 6%.Turkish Phys So
Bioleaching of marmatite flotation concentrate with a moderately thermoacidophilic iron-oxidizing bacterial strain
No full textBioleaching of a marmatite flotation concentrate with a moderately thermoacidophilic iron-oxidizing bacterial strain (MLY) was investigated in batch experiments. Experimental results showed that the dissolution rate of marmatite was influenced markedly by pH, temperature, pulp density and particle size of ore. The bioleaching of the concentrate by the moderate thermophile was more effective when carried out under the higher acidity and temperature compared with Acidithiobacillus ferrooxidans. The adapted strain of the moderate thermophile could provide more rapid and complete oxidation of marmatite than its original strain and in the sterile control. (c) 2005 Elsevier Ltd.

No full textThe study of CMOS based VCO with active inductor and its design methodology
No full textActive Inductors are useful in reducing the large chip area typically consumed by spiral inductors, as well as providing larger inductance values and higher quality factors that otherwise cannot be achieved by spiral inductors. Integrated inductors find application in many radio frequency (RF) front end integrated circuits, including impedance matching, filtering, biasing and in oscillator circuits. Nonetheless, because of the interdependent relationship of the self-resonant frequency and quality factor it is often difficult to meet desired circuit requirements. Additionally, active devices pose problems of higher power consumption , noise figure and potential instability. This thesis begins with the study of active inductors, the Wu active inductor in particular, and considers tuning methods based on the Wu active inductor topology. Starting with the small-signal model, the emulated inductance and quality factor expressions are derived. Next, the operation of active inductors under large-signal is closely examined. Comparisons between a passive and an active VCO are made. The active inductor based voltage-controlled oscillator (Active VCO) is studied extensively, and the methods of improving the performance under large signal-behavior are discussed. Then a design procedure based on gm/ID methodology is proposed. A Matlab script that can be applied to gyrator-C based active inductors is developed to determine the sizing of the transistors for a desired inductance and resonant frequency. Cadence Virtuoso is used for simulations, and extraction based on an IBM 8RF technology file. Finally, a low power active VCO is designed, simulated and laid out.M.S.Includes bibliographical referencesby Sy-Min Chuen
