This element has two independent inputs for two base components of the electromagnetic field: the transverse electric and magnetic components which determine the Poynting vector. The advantage with this kind of transducer compared to those in which digital or analog multipliers of the electrical signals are used, is that the electromagnetic components are used in their natural forms, without any additional conversion. This permits the use of these magnetoresistive multipliers operate in a wide frequency band with good accuracy.","PeriodicalId":160058,"journal":{"name":"IMTC/98 Conference Proceedings.

A resistive network with end point linearity referred to the full scale of 15% has been used to emulate a sensor pair and the two input signals have been sampled with a 8-bit A/D converter.","PeriodicalId":160058,"journal":{"name":"IMTC/98 Conference Proceedings.

The proposal method uses Fourier transform infrared spectroscopy of attenuated total reflection method (ATR spectroscopy). The concentration region of pesticide multiresidues in the agricultural products could be measured rapidly. The partial least squares regression models of the typical pesticides were calibrated by a training set of lettuce heads produced in the fields. The measuring time is about ten minutes that is the shortest among the conventional method of analytical chemistry, of which measuring time are some hours. It could be noted that the pesticide application could be properly controlled by the at-line measurement based on the proposal method. This paper also describes the validation of this method by using the test set of lettuces and some discussions about the improvement and the,vide application or food safety and inspection.","PeriodicalId":160058,"journal":{"name":"IMTC/98 Conference Proceedings.

The system was calibrated with measurements on air and decanol and verified with measurements on octanol, hexanol, and pentanol. The standard error for the polar alcohols used for verification was 2.3% for the dielectric constant and 7.6% for the dielectric loss factor. Although measurements were taken on static samples, the sample holder is designed to accommodate flowing grain.","PeriodicalId":160058,"journal":{"name":"IMTC/98 Conference Proceedings.
