A thermistor leaf thermometer.
An instrument is described which allows measurements of leaf temperature within about 0.3 C. It consists of a special thermistor probe, a small circuit box, and a standard ammeter. The circuit box can easily be fixed to the meter and contains a battery, which passes 0.3 milliampere through the thermistor, and also contains an integrated circuit amplifier, so that the meter reads 20 C full scale...
متن کاملA New Cryogenic Diode Thermometer
While the introduction of yet another cryogenic diode thermometer is not earth shattering, a new diode thermometer, the DT-600 series, recently introduced by Lake Shore Cryotronics, possesses three features that make it unique among commercial diode thermometers. First, these diodes have been probed at the chip level, allowing for the availability of a bare chip thermometer matching a standard ...
متن کاملDetecting entanglement with a thermometer
We present a general argument showing that the temperature as well as other thermodynamical state variables qualify as entanglement witnesses for spatial entanglement. This holds for a variety of systems and we exemplify our ideas using a simple non-interacting Bosonic gas. We find that entanglement can exist at arbitrarily high temperatures, provided that we can probe smaller and smaller regio...
متن کاملRobust Speech Recognition by Combining Short-Term and Long-Term Spectrum Based Position-Dependent CMN with Conventional CMN
In a distant-talking environment, the length of channel impulse response is longer than the short-term spectral analysis window. Conventional short-term spectrum based Cepstral Mean Normalization (CMN) is therefore, not effective under these conditions. In this paper, we propose a robust speech recognition method by combining a short-term spectrum based CMN with a long-term one. We assume that ...
متن کاملAppraisal of the Cmn/helium Kapitza Resistance
It is argued that the thermal resistance between cerium magnesium nitrate (CMN) and pure He,He containing He* impurity or dilute He in He"* can be understood in terms of the phonon bottlenecked spin-lattice resistance within the CMN and a size dependent thermal boundary resistivity. The fact that emerges is that the phonon bottleneck within the CMN is strongly dependent upon whether the CMN is ...
