Girls signs the painting- Glaidis, Basils niece. Dorian stole her heart. Also important in later recognising the corpse. In Wilde's original, Sybil Vane is a Shakespearean actress whom Dorian observes playing Juliet, rather than the gifted dance-hall singer seen in this film. This necessitates altering Dorian's motive for breaking up with her. In the novel, her acting has become shallow as a result of really falling in love with Dorian, and his sense of illusion has been dissipated. In the film, she reacts poorly to his confessions of sensual temptations, which dismays him. Dorian woos her at first wit his looks and also his piano playing (Prelude). Sybil sings well even with Harry and basil watching. Harry gives the idea of a test whether Sybil will stay for pleasure or not. Sybil fails the test and dorian dumps her in a letter.(in the book face-to-face) Dorian's final marriage before his death is to a parson's daughter in the novel; In the film, it is

Channels – multiple analog signal inputs to the ADC that can be individually selected or selected through a multiplexor. 7. Linearity – Describes how an ADC conveter follows a linear function. 8. Operating temperature – A temperature at which the ADC functions optimally, usually given by the manufacturer. 9. Power dissipation – The proportion of power dissipated (through heat) when the ADC is working. Question 2: An 8 bit ADC has a reference voltage of 5V.

The voltage across the sense resistor (amplified if necessary) drives the invert- ing input of the opamp. The opamp will attempt to keep the motor current equal to the reference voltage. A circuit like this is electrically quieter than the chopper, but it is much less efficient. The power opamp will dissipate considerable power since it will carry the same current as the motor coil and will usually have a significant voltage drop. The power dissipated by the opamp at any time is given by P = ( V - Vm) I where V is the supply voltage, Vm is the motor coil voltage, and I is the coil current. A linear drive like this requires a negative supply voltage. It is possible to build a bridge-driver using two opamps that operates from a positive supply and works like the H-bridge, driving one side of the coil positive or negative with respect to the other.

that his dispatches were being opened. But they were enciphered, and, in the manner of diplomats everywhere, he felt safe because he thought that the Russians were too dumb to break his cipher. He may have been right about Russians, but three Germans in the black chamber were making mince pie out of it. He erred in writing home with a deplorable lack of gallantry about the Czarina, remarking that she was "given entirely to her pleasures" and was "so frivolous and so dissipated." The interceptions were seen as a matter of course by Count Aleksey Bestuzhev-Ryumin, grand chancellor of the imperial court. He had been waiting to strike back at Chetardie, who had organized a cabal against him because of his Anglophile tendencies. He showed the solutions to Elizabeth, who, blinded by her own French leanings, refused to believe them until he deciphered them in her presence. The next day, June 17, 1744, as Chetardie entered his residence, he was handed a note ordering
