Mobile sensors equipped with sampling, sensing, data acquisition, wireless transmission and power generation systems are being designed, fabricated, and tested, and prototypes are expected to be released in the very near future.
Such an attractive strategy is well catered for by both the capabilities and distributed nature of wireless sensor networks and the mobility of robots performing the sampling (sensing) tasks.
By introducing a model-based multirate predictor and a forward-model disturbance observer, we show that the inter-sample disturbances can be fully attenuated despite the limitations in sampling and sensing.
The objective is to maximize network lifetime while fulfilling diversified coverage constraints, i.e., different targets may require different sensing quality in terms of the number of transducers, sampling rate, sensing data rate, etc.
The general principle of AFM is to scan a sharp tip over the surface of a sample, while sensing the so-called near-field physical interactions between the tip and the sample.
Bioengineer Daniel Fletcher of the University of California, Berkeley, wondered whether an automated computer program could instead detect the worms in blood samples by sensing their telltale wiggling.
One particularly elaborate needle-based device would collect a tissue sample upon sensing a foreign object, before releasing an identifying dye onto the penis, as well as a tissue irritant.
By working with each sample and sensing your responses to it, you soon will know the wood or woods that hold the most appeal for you.
Assuming each individual sample senses the same temperature difference ΔT under the same heating power [20], the data in Fig. 3a indicates that they have the same sensitivity ΔS Cr-Pd.
In this way, every autonomous agent [8], be it human, animal, or artificial, must frequently sample (sense) its environment, process (make sense of) the input from such sampling, and select an appropriate response (action).
BH control is achieved only in large sample sense, as BH showed that as the number of tests goes to infinity, the expected rate of false positives is bounded above.
