Topics in quantum physics: Schrodinger's cat problem - time measurement accuracies in quantum mechanics
… the problem. In the second part, I discuss the time measurement related issues in quantum mechanics. Since there does not exist any time operator in quantum mechanics generally, time is not directly measurable. Therefore we should devise other methods to register time. We study different …

New Framework for Real-time Measurement, Monitoring, and Benchmarking of Construction Equipment Emissions
… of construction. This research focuses on real-time measurement of emissions from non-road construction equipment and development of a monitoring-benchmarking tool for comparison of expected vs. actual emissions. First, exhaust emissions were measured using a Portable Emission Measurement System …

Photoperiodic time measurement and seasonal adaptation of the southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera : Pyralidae)
… severe environmental pressure. Most usually, the timely completion of the life cycle and the institution of a dormant state are critical to survival under winter conditions. In this respect, diapause may be a relatively recent adaptation in this insect as the result of its territorial expansion. …

A real-time optical measurement system
Measurement of the dynamics of flexible structures is difficult because the motion is often complex and the structures are not well suited to the attachment of sensors. As a result, non-contact optical systems are used. However, optical systems produce large amounts of data which make their use in …
