Is there a way of a UMAX Astra 2100U scanner working on Vista?
No. There is no known software that will enable you to use this scanner on Vista. Sorry. I wish there were because I have one.

How much power is dissipated in the driver which drives a capacitor when its driven with a less than 50 percent duty cycle?
The simplified equivalent circuit of the setup would be a resistor R and a capacitor C in series. Where R is the output resistance of the driver circuit and C is the capacitor driven. We can assume the power is dissipated in the equivalent output resistance R of the driver circuit.___o---|___|---+-------oR C+--------->|Ur(t)The average power Pavg can be calculated from the effective value of the voltage on the resistor Ur,eff by the known simple formula for power:Pavg = Ur,eff * Ir,eff = Ur,eff2 / R (1)The effective value of the voltage on the resistor can be calculated by following formula.________________________/ TUr,eff = \/ (1/T) * integral ( ur(t)2 * dt ) (2)0In case of the above equivalent circuit and when assuming a voltage symmetrical square wave form drive signal ur(t) can be defined as_ __t__ T1 _ __t__ Tur(t) = ( 2 Umax * e R*C ) + ( -2 Umax * e R*C ) (3)0 T1where Umax is the amplitude of the square wave, thus 2 * Umax is the peak to peak amplitude of the symmetrical square wave, and T1 is time of the polarity switching in the square wave within the period.In praxis the positive and negative parts of the driving wave are provided through different branches of the driver circuit. Thus each half wave is dissipated on a different resistor. In this case the equation (3) can be split up into two parts_ __t__ T1 Tur1(t) = ( 2 Umax * e R1*C ) + ( 0 ) (3a)0 T1T1 _ __t___ Tur2(t) = ( 0 ) + ( -2 Umax * e R2*C ) (3b)0 T1For the positive side the integral of Ur1,eff in equation (2) solves to_____________________________/ _ __2_T1__Ur1,eff = 2 Umax \/ (1/T) * (R1*C/2) * ( 1 - e R1*C ) (4a)and from (1) follows the average dissipated power on R1 (positive side of the wave)2 _ __2_T1__Pr1,avg = 2 Umax (C/T) * ( 1 - e R1*C ) (5a)Analogous to (5a) the dissipated power on R2 (negative side of the wave) is2 _ __2_(T-T1)__Pr2,avg = 2 Umax (C/T) * ( 1 - e R1*C ) (5b)The total power dissipation is the sum of the two half wavesPagv,total = Pr1,avg + Pr2,avg (6)This is also valid if R1 and R2 are the same resistor R as assumed at the beginning.
Is there any computer hardware or software that can transpose hand written material into computer readable form?
Optical Character Recognition (OCR), automatic document recognition (ADR) and Electronic Document Management (EDM), announced today the worldwide release of a brand new version of its flagship OCR software for the Windows platform, Readiris Pro 9. forum.ecoustics.com There is a program that's called Omni Page, mine came with my scanner; UMAX Astra 1600U software. Another program came with my CANON printer, Adobe photo deluxe3.0. Read this: onix.com Also ADOBE has a bundled program. I have not used it myself.

The effective value of ac voltage is calculated as?
EFFECTIVE HOW ABOUT AVERAGE .639 of peak.AnswerThe 'effective' value of an a.c. voltage (or current) is the same as its 'root-mean-square' (r.m.s.) voltage which, for a sinusoidal waveform, is 0.707 Umax.The 'average' value of an a.c. voltage (or current) is zero over a complete cycle, or 0.639 Umax, over half a cycle (usually applied to rectified waveforms).
How do you calculate integer data type?
To determine the range of an integer data type you first need to know the size of the integer, in bytes. This is implementation-dependant, so never assume it will always be 4 bytes. On a 64-bit system, it could be 4 or 8. To accurately determine the size of any datatype, always use the sizeof() operator. If you don't, then you are guaranteed to run into major problems when porting programs between compilers and architectures. Once you have the size, determining the range is fairly easy. The following program contains two function overloads to determine the range of an int and an unsigned int, using bitwise shift operations. The main function tests both functions, showing the ranges in both decimal and hexadecimal (example output is shown below). #include <iostream> #include <iomanip> size_t GetRange(const int& i, int& iMin, int& iMax ) { int sizeInBits = sizeof(i) * 8; iMin = 1; iMin <<= --sizeInBits; iMax = 1; while(--sizeInBits) { iMax <<= 1; iMax |= 1; } return(sizeof(i)); } size_t GetRange(const unsigned int& u, unsigned int& uMin, unsigned int& uMax ) { unsigned int sizeInBits = sizeof(u) * 8; uMin = 0; uMax = 1; while(--sizeInBits) { uMax <<= 1; uMax |= 1; } return(sizeof(u)); } int main() { using namespace std; const int w=17, z=12; int x, iMin, iMax; unsigned int y, uMin, uMax; size_t iSize=GetRange(x, iMin, iMax); size_t uSize=GetRange(y, uMin, uMax); cout<<setw(z)<<"Type"<<setw(w)<<"int (x)"<<setw(w)<<"unsigned int (y)"<<endl; cout<<setw(z)<<"Size (bytes)"<<setw(w)<<iSize<<setw(w)<<uSize<<endl; cout<<setbase(10); cout<<setw(z)<<"Min (dec)"<<setw(w)<<iMin<<setw(w)<<uMin<<endl; cout<<setw(z)<<"Max (dec)"<<setw(w)<<iMax<<setw(w)<<uMax<<endl; cout<<setbase(16); cout<<setw(z)<<"Min (hex)"<<setw(w)<<iMin<<setw(w)<<uMin<<endl; cout<<setw(z)<<"Max (hex)"<<setw(w)<<iMax<<setw(w)<<uMax<<endl; cout<<endl<<endl; return(0); } Output: Typeint (x)unsigned int (y)Size (bytes)44Min (dec)-21474836480Max (dec)21474836474294967295Min (hex)800000000Max (hex)7fffffffffffffff Note the way signed integers are represented in hexadecimal. It looks odd but the binary representation of -1 in 8-bit notation is 11111111 (FFh), not 10000001 (81h) as you might expect. It makes more sense when you realise 11111111+00000001=00000000 which, in decimal, would be -1+1=0.
What is Proportional Band?
In practice, the controller output is limited, either by its own limitations or by the limitations of the corresponding actuator. Let umax and umin denote the minimum and maximum output of the controller. The proportional band of the controller is then defined as:In the ideal case, a controller can have an unlimited output. The proportional band (PB) is then defined as:This definition of proportional band is often used instead of the controller gain. The value is expressed in percent (%).
