Book excerpt: Snow penetrometers create a specific application for a force sensor with specifications that are over achieved at great cost when using traditional load cells. A moderately priced, compact force sensor suitable for this application does not exist, and numerous force-sensing technologies were investigated, from spring and displacement transducer combinations, to strain gauges mounted on plastics, to pressure transducers. The high dynamic range, linearity, and electrical simplicity of low-cost piezo-resistive pressure sensors lent well to rapidly developing a working design on a small budget. Preliminary prototypes show promising results where the natural frequency requirement is 60% above the target specification at wn = 10497 rad/s +/- 92 rad/s. The sensor is nearly ideally damped with damping ratio, [zeta] = .43 +/- .04. A linear model results in acceptable hysteretic error for mid and upper range force values, but the sensor performs inaccurately below 2.8 N (greater than 20% error). While the sensor's performance isn't perfect for all criteria, snowpack simulation tests suggest that the sensor's shortcomings are acceptable for the targeted application of measuring relative snow hardness.

Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
