We have obtained high-resolution cw coherent anti-Stokes Raman spectra of the nu(1) Q branch of methane in an underexpanded supersonic jet at temperatures as low as 31.5 K and pressures below 2 Torr.

This seemingly basic equation actually hides some sophisticated assumptions and concepts. First, it applies only to the time varying, alternating, or ac, components of the current and voltage. Secondly, it is not sufficient to just tell how big the voltage and current signals are, we must also say how they are related in time, since they are both timevarying, ac quantities. Finally, the sizeand...

This paper explores NFC based applications adequate for the use in retail stores and analyses the influence that these could have on the prevailing customer shopping process. It emphasizes the fact that NFC could provide shoppers with more benefits beyond faster payments. On the one hand, NFC based rebate coupons and loyalty cards could further accelerate the check-out process. On the other han...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...
