In Fourier spectroscopy, the absorption mode spectrum V(f) and the dispersion mode spectrum U(f) are computed from the experimentally measured impulse response /z(t). Clearly, this general principle must be applicable here as well. Some consequences of practical importance will be discussed in this paper. In practical Fourier spectroscopy a periodic pulse sequence is used to excite the spin sys...

Fluorescence correlation spectroscopy (FCS) is becoming increasingly popular as a technique that aims at complementing live cell images with biophysical information. This article provides both a short overview over recent intracellular FCS applications and a practical guide for investigators, who are seeking to integrate FCS into live cell imaging to obtain information on particle mobility, loc...

In this paper, a fuzzy engineering economic decision model is derived to evaluate the investment feasibility of wind generation project. A straightforward vertex parameters’ fuzzy mathematics operation using the function principle is derived as an alternative to the traditional extension principle, and is applied to evaluate a number of different economic decision indexes. Compared to the exten...

In this paper, a new fractional exothermic reactions model with constant heat source in porous media considering the memory effect is proposed. Applying complex transform, converted into its partner. Then variational principle of problem successfully established. Based on obtained principle, Ritz method used to seek solution model. Finally, correctness and effectiveness proposed are illustrated...
