The Dirty Harry Problem

Policing constantly places its practitioners in situations in which good ends can be achieved by dirty means. When the ends to be achieved are urgent and unquestionably good and only a dirty means will work to achieve them, the policeman faces a genuine moral dilemma. A genuine moral dilemma is a situation from which one cannot emerge innocent no matter what one does-employ a dirty means, emplo...

Design of Nyquist and Near-Nyquist Pulses with Spectral Constraints

Two design procedures, one based on switched pulse shapes, and the other based on alternating projections in the time and frequency domain, are used to obtain interference and jitter-free or reduced interference and jitter (near-Nyquist) pulse-shaping filters. The latter method, that incorporates both frequencyand timedomain constraints into the linear filter design procedure, allows common pul...

I t is now 16 years since Nowikoff (1908) accelerated the division rate of Paramecium by adding thyroid gland to his cultures. Later , Shumway (1914) reached the same conclusion after a series of more critical and painstaking experiments, and in the following year Budington and Harvey (1915) showed tha t thyroids from various vertebrates would produce similar results. Still later, Shumway (1917...

Superposition is a mapping on point configurations that sends the n-tuple (x1, . . . , xn) ∈ X into the n-point configuration {x1, . . . , xn} ⊂ X , counted with multiplicity. It is an additive set operation such the superposition of a k-point configuration in X is a kn-point configuration in X . A Poisson superposition process is the superposition in X of a Poisson process in the space of fini...
