Heat Efficiency in Municipalities

Известия Российской академии наук. Энергетика, 2023
A complex analysis of heat supply systems from the standpoint of reliability, efficiency and environmental friendliness has been carried out. It has been revealed that in heat supply systems the weakest link in terms of reliability is heat networks. The main number of accidents accompanied by interruption of thermal energy supply occurs on them.

Efficiency of Brownian heat engines

Physical Review E, 1999
We study the efficiency of one-dimensional thermally driven Brownian ratchets or heat engines. We identify and compare the three basic setups characterized by the type of the connection between the Brownian particle and the two heat reservoirs: (i) simultaneous, (ii) alternating in time, and (iii) position dependent. We make a clear distinction between

Efficient Calculation of Heats of Formation

The Journal of Physical Chemistry A, 2009
An efficient procedure has been devised for calculating heats of formation of uncharged, closed-shell molecules comprising H, C, N, O, F, S, Cl, and Br. Known as T1, it follows the G3(MP2) recipe, by substituting an HF/6-31G* for the MP2/6-31G* geometry, eliminating both the HF/6-31G* frequency and QCISD(T)/6-31G* energy and approximating the MP2 ...
