Abstract: Techniques are provided for managing airport slot reservations using a shared database network. A computing device receives information of one or more open airport slots. The availability of the open airport slots is validated through the shared database network and is stored in a shared ledger of the shared database network. The open airport slots are published to one or more carriers to initiate electronic transactions of the open airport slots. The computing device receives one or more bid transactions from the air carriers for the open airport slots. Each bid transaction has associated bid information. The bid transactions are validated using predefined validation rules, and they are allotted to corresponding open airport slots based on the predefined validation rules and the bid information. The bid transactions allocated to the corresponding open airport slots are published to the shared ledger.

Abstract: A method and apparatus for interrogating a sample that exhibits molecular rotation are disclosed. In practicing the method, the sample is placed in a container having both magnetic and electromagnetic shielding, and Gaussian noise is injected into the sample. An electromagnetic time-domain signal composed of sample source radiation superimposed on the injected Guassian noise is detected, and this signal is cross-correlated with a second time-domain signal produced by the same or similar sample, to produce a cross-correlated signal with frequency domain components. The latter is plotted in the frequency domain by a fast Fourier transform to produce a frequency domain spectrum in a frequency range within DC to 50 KHz. From this spectrum, one or more low-frequency signal components that are characteristic of the sample being interrogated are identified.
