“…In addition, it is required that the designed synchronous control full-slave scheme eliminate the influence of communication delay. We need to get rid of the limitation of the pulse platform signal further to simplify the way of network communication [7]. We use Matlab software simulation software to set the synchronous control mode.…”

After the input signal of e-commerce network information enters the network, it will inevitably be polluted by network delay. There is an error between the network output signal obtained by the receiver and the input signal of the transmitter. We combine control combination algorithms with mathematical models. And the power spectral density function is introduced into the signal transmission mathematical model of the e-commerce platform. Experiments prove that the new model is closer to the transmission efficiency change of the actual network communication signal than the traditional model.

Molecular logic gates (MLG) are molecules which perform logic operations. Their integration into a computing system is a very difficult task which remains to be addressed. The problem lies in the field of signal exchange between the gates within the system. We propose using non-adiabatic excitation transfer between the gates to address this problem while absorption and fluorescence are left to communicate with external devices. Excitation transfer was studied using the modified Bixon-Jortner- Plotnikov theory on the example of the 3H-thioxanthene-TTF-dibenzo-BODIPY covalently linked triade. Several designs of the molecule were studied in vacuum and cyclohexane. It was found that the molecular logic system has to be planar and rigid to isolate radiative interfaces from other gates. Functioning of these gates is based on dark πσ∗-states in contrast to bright ππ∗-states of radiative interfaces. There are no fundamental difference between ππ∗ → πσ∗ and ππ∗ → ππ∗ transitions for cases when an exciton hopes from one gate to another. The rates of such transitions depend only on an energy gap between states and a distance between gates. A circuit is highly sensitive to the choice of solvent which could rearrange its state structure thereby altering its behavior. According to the obtained results, non-adiabatic transfer can be considered as one of the possible ways for transmitting a signal between MLGs.
