Signal arithmetic; Signals and noise; Smoothing; Differentiation; Resolution enhancement; Harmonic analysis; Convolution; Deconvolution; Fourier filter; Integration and peak area measurment; Curve fitting.Fri, 28 Dec 2001 00:00:00 -0800Measurements: can you believe them?
http://www.merlot.org/merlot/viewMaterial.htm?id=82609
Reliability of a measurement; an introduction to simple statistics for science students. Average, mean, deviation from the mean, standard deviation, systematic and random error.Fri, 5 Nov 2004 00:00:00 -0800Acid-base equilibria and calculations
http://www.merlot.org/merlot/viewMaterial.htm?id=82815
covers the quantitative treatment of acid-base equilibria at somewhat greater breadth and depth than is available in standard textbooks. The principles of electroneutrality and mass balance are used to develop exact solutions for common equilibrium problems, and the common approximations and their limitations are explored. At the other extreme, there is an extensive treatment of the use of log-concentration vs. pH graphs for obtaining approximate solutions of equilibrium problems without arithmetic. There is a detailed discussion of the proton-free energy concept (without the thermodynamics!) that is helpful in understanding more complex acid-base systems. Other sections cover practical methods of solving quadratic and higher-order equations, graphical solution of equilibrium problems, titration curves, the carbonate system, physiological applications, and acid rain.Fri, 3 Dec 2004 00:00:00 -0800Measurements: drawing conclusions from data
