1. A static population of 900,000 people lives in an area with a background ra diation level that gives each person an extra 125 mrem (whole-body) per year of low LET exposure over that received by people in other parts of the coun try.
(a) Estimate the collective gonad dose to the reproductive population.
(b) Estimate the number of radiation-induced cases of hereditary illness that occurs in each generation.
(c) Compare this number to the natural incidence of genetic illness in this population.
find the spectrum of the signal s(t) that results from the use of natural sampling,assuming that time t=0 corresponds to the midpoint of a rectangular pulse in c(t). show that the original signal m(t) may be recovered exactly from its naturally sa..
Suppose a knowledge base contains just one sentence Ðx As High As (x, Everest). Which of the following arc legitimate results of applying Existential Instantiation?
a 500-turn toroid of square cross section has an inner radius of 10cm and an outer radius of 15cm. The relative permeability of the core is 1000. For a current of 10A in the coil, calculate(a) the energy density, (b)the stored energy
An AC induction motor is rated at 1750 rpm with a line frequency of 60Hz. If the motor is operated on a 50 Hz line, what will be its approximate speed in RPM?
Write Verilog code that implements a 4-bit adder with carry-lookahead (i.e., not a ripple-carry adder). Your designshould have an output C4 for a carry generated in the mostsignificant bit stage and an overflow bit V for use with signed numbers.
Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether B is greater than A. The circuit has one output X, so that X = 1 if A = B.
Indicate the use of each memory in the microcontroller (HCS12). In other words, state which one is used for code, program variables, and variables that must remain when the power is turned off.
Give an expression for the detection error probability for a mobile in soft handoff between two base-stations. You may need to make several simplifying assumptions here. Feel free to make them but state them explicitly.
If the surface heat flux varies linearly with x, such that q"s (W/m2) = 500x (m), what are the values of q, Tm,o, Ts,i, and Ts.o? Sketch the axial variation of T, and Tm. On the same figure, also sketch (qualitatively) the axial variation of Ts an..
Two thin rods of length L lie on the x axis. One of them has a charge of -Q uniformly distributed along its length and is positioned between x = -L and x = 0. The other one has a charge of +Q uniformly distributed along its length.
a voltage divider is required to produce a 5.5V output from a 12V source. if one of the resistor values is 1.0k, what value is required for the second resistor so that the voltage across the 1.0k resistor is 5.5V
