1. Hamming code can correct any one error; might there be a (14, 8) code that can correct any two errors? Optional extra: Does the answer to this question depend on whether the code is linear or nonlinear? 2. Design an e ...

(a) Find the best linear approximation, L(x), to f(x) = ex near x = 0. (b) What is the sign of the error, E(x) = f(x)  L(x) for x near 0? (c) Find the true value of the function at x = 1. What is the error? (Give decima ...

The distance, s, of a moving body from a fixed point is given as a function of time, t, by s = 20e t/2 . (a) Find the velocity, v, of the body as a function of t. (b) Find a relationship between v and s, then show that s ...

During April 2006, Zimbabwe's inflation rate averaged 0.67% a day. This means that, on average, prices went up by 0.67% from one day to the next. (a) By what percentage did prices in Zimbabwe increase in April of 2006? ( ...

In the Bayesian graphical model community, the task of inferring which way the arrows point  that is, which nodes are parents, and which children  is one on which much has been written. Inferring causation is tricky be ...

Let the power spectrum be a Gaussian function of frequency. Since the Fourier transform of a Gaussian is a Gaussian, the autocovariance function corresponding to this power spectrum is a Gaussian function of separation. ...

There is a threephase IG of 110 V, 60 Hz, 4 poles, 1900 rpm, Y stator connection, and an equivalent circuit given as R 1 = 0.20 Ω, R 2 = 0.42 Ω, X 1 = 0.15 Ω, and X 2 = 0.43 Ω; R 2 and X 2 refer to the stator. The ...

It has been generally known to Si technologists (such as the CCD or Charge Coupled Device and high efficiency solar cell engineers) that iron impurity is a rather nuisance recombination center because it is highly unstab ...

Assume that carrier screening from impurity electrons will make the impurity bound state disappear by disregarding the oneelectron per oneimpurity difficulty (the idea of screening by the electron density fluctuation r ...

What do you think are the two most important functions of the family? Give at least one example for each function to demonstrate why you think it is important to a person's overall life outcomes. Explain whether you thin ...
