Sketch a pressure versus volume and a temperature versus volume diagram for the process described. 10. Derive a formula for the efficiency as a function of the compression ratio, r. Plot a curve of efficiency vs r in the range 1<r⩽100. 11. If this ratio were to reach the (unrealisti...
b–c Stereo diagram of the NAM binding sites. The NAM molecules located in the catalytic site (b) and tunnel (c) are shown in green and yellow, respectively. Hydrogen bonds between the protein and NAM are shown as yellow dashed lines. Residues contacting NAM molecules are also depicted as...
Exergy, which is indicative of the second rule of thermodynamics, is expressed as the highest effective activity that is hypothetically accessible from a thermodynamic system. Hence, the exergy efficiency of a PV/T collector is explained according to the allocation of this highest theoretically accessi...
Finally, the suggested hybrid system was assessed utilizing the results acquired from all of this measurement equipment, which included the thermal and electrical efficiency, COP. 2.4. Thermodynamic Analysis The input energy of a PV system determines the output energy ratio (solar radiation on the ...
Thermodynamic Pareto optimization of turbojet engines using multi-objective genetic algorithms Multi-objective genetic algorithms (GAs) are used for Pareto approach optimization of thermodynamic cycle of ideal turbojet engines. On this behalf, a new ... K Atashkari,N Nariman-Zadeh,A Pilechi,... ...
Au-Pt system; phase diagram; thermodynamic assessment; Calphad method; 1 Introduction Recently, intense research has been focused on the Au-Pt and Au-Pt based systems because these alloys exhibit unusual mechanical properties, physical properties, chemical stability and biological compatibility and have...
The ARO algorithm has almost the same amount of performing both detour food searching and random hiding in the iterative process, which contribute significantly to balancing exploration and exploitation. Figure 6 shows the schematic diagram of probability calculation of the detour food searching [37]....
