Further, it is demonstrated that the present knowledge with regard to the error in absorption spectrophotometry is necessary to be reexamined. The total scale of transmittance can literally be used for measurements, unfolding workable dynamic ranges about two orders of magnitude lower than usually and thus absorption spectrophotometry can efficiently compete with other methods of analysis with respect to detection limits.展开更多

I have tried to separate it as an entity, which together with other textual techniques and strategies shall create applicable theoretical messages towards an artistic creation. Eco＇s （1994） work itself, gives an opportunity to exemplify his theoretical claims. Using my examples, I have tried to show how a work of art can be rendered narrative, a subject to contemporary techniques and cooperativeness with the reader. One of the main issues I have explained is the time factor, seen from the linguistic and semiotic prospective. I consider that Eco＇s treatment of the relation between reality and fiction is of a semiotic nature. One of the main elements it contains （and definitely makes such a difference possible）, is the time factor. The delay （lingering） part treats works of art separately, and gives one of the ways to render artistic works readable, worth having an aesthetic value, in their way to transmitting a message to the audience.展开更多

The proposed system consists of a reader antenna inductively coupled to the sensor circuit, a readout circuit, and a personal computer （PC） post processing unit. The readout circuit generates a voltage signal representing the sensor＇s capacitance. The frequency of the reader antenna driving signal is a constant, which is equal to the sensor＇s resonant frequency at zero pressure. Based on mechanical and electrical modeling, the pressure sensor design based on the high temperature co-fired ceramic （HTCC） technology is conducted and discussed. The functionality and accuracy of the readout system are tested with a voltage-capacitance measurement system and demonstrated in a realistic pressure measurement environment, so that the overall performance and the feasibility of the readout system are proved.展开更多
