Stability Condition in Terms of the Pole Locations A causal lti digital filter is BIBO stable if and only if its impulse response h[n] is absolutely summable, i.e

Pronunciation of mathematical expressions The pronunciations of the most common mathematical expressions are given in the list below. In general, the shortest versions are preferred (unless greater precision is necessary)

Z-Transform The DTFT provides a frequency-domain representation of discrete-time signals and LTI discrete-time systems Because of the convergence condition, in many cases. the DTFT of a sequence may not exist As a result, it is not possible to make use of such frequency-domain characterization in these cases

1. The\Wager\and the Practical Rationality Principle Practical Rationality Principle: The practically rational thing to do is the thing with the highest expected value(or utility \) Version A: Do the thing with higher expected value than all its competitors --In the case of a tie, neither action/belief is permitted Version B: Find the actions with highest expected value and perform whichever of them you like --In the case of a tie, Theism is practically rational.

This socio-economic growth, together with the rapid expansion of Hong Kong's port and airport facilities and increase in cross boundary traffic, have placed tremendous demands on transport

The State of the HK Economy The Hong Kong economy staged a sharp rebound over the course of 1999, recovering robustly from the severe setback brought about by the earlier Asian financial turmoil. The recovery was strongly export-led. In consequence, there was a marked increase in the combined visible invisible trade surplus over the year

MTs are hollow, cylindrical structures that occur in nearly every eukaryotic cell that has been scrutinized with EM. MTs have an outer diameter of 24~25nm, a wall thickness of approxim ately 5 nm, and lengths that may extend across the length or breadth of a cell. 1. Tubulin Globular tubulin subunits are arranged in 13 longitudinal row
