Spatial and temporal control of chemical processes

Point processes , spatial – temporal

Temporal and spatial organization of chemical and hydrodynamic processes. The system Pb(2+)-chlorite-thiourea.

Precise spatio-temporal organization of chemical, hydrodynamic, and mechanical processes is typical for biological systems where particular chemical reactions have to accrue in precisely assignment place and time. It is rarely studied and observed in chemical systems. We report unusual precipitation pattern formation of PbSO(4) in chemical media (Pb(2+)-Chlorite-Thiourea System). We have found ...

Spatial and Temporal Structures in Cognitive Processes

The structures of space and time are identified as essential for the realization of cognitive systems. It is suggested that the omnipresence of space and time may have been responsible for neglecting these dimensions in knowledge processing in the past. The evolving interest in space and time in cognitive science and some of the current conceptions of space and time are briefly reviewed. It is ...

Spatial and Spatio-temporal Point Processes

The present paper gives the background to point processes in space and time. Some special types of spatial and spatio-temporal models of point processes are introduced with the emphasis to Cox processes. Their basic properties are described and some characteristics are calculated. The simulation of one of these models is shown. Introduction At present, the theory of point processes is well esta...

Coherent Control of Physical and Chemical Processes

The method of coherent control allows one to exploit classical and quantum-mechanical interferences to control the dynamics of atomic, molecular, and solid-state systems, and to drive them into novel, non-equilibrium states. This technique has been widely applied to control both electronic and vibrational degrees of freedom in a variety of systems. Typically, a sequence of femtosecond pulses ex...
