In fact, it appears that for systems and processes with more than one utility (mainly mechanical or electrical power), energy conservation (First Law) is limited for representing their efficiency. Consequently, exergy analysis combining the First and Second Law seems essential for optimization of ...
The concept of non-Hermiticity has expanded the understanding of band topology, leading to the emergence of counter-intuitive phenomena. An example is the non-Hermitian skin effect (NHSE)1,2,3,4,5,6,7, which involves the concentration of eigenstates at the boundary. However, despite the pote...
One of the key means of reaching theobjectives was to implement mechanical ventilation with low pressure loss and therefore low energyconsumption. The project consists of two buildings, building one is 6 stories high, and building two is 4 stories high. The buildings have a gross area of 50,...
Increasing the energy consumption in pumps and obstructing the two-phase flow system are well-known examples regarding the destructive influences of high pressure drop inside channels11,12,13. Consequently, the optimal design of heat exchangers necessitates comprehensive predictive tools for pressure drop...
The study shows that the energy harvesting efficiency can be increased by up to 50% for a particular reduced velocity. Introduction Flow-induced vibrations phenomena (FIV) cover a comprehensive class of generally non-linear problems that lead to self-excited oscillations. Examples of FIV phenomena ...
A comparison of muscular mechanical energy expenditure and internal work in cycling The hypothesis that the sum of the absolute changes in mechanical energy (internal work) is correlated with the muscular mechanical energy expenditure (MME...

One way to reach these targets is to combine both natural and mechanical ventilation advantages into a hybrid system. In addition, reliable design tools are needed to generate guidelines on control strategies. Examples of existing hybrid ventilation and control strategy systems in office and ...
The exploitation of both conventional and unconventional hydrocarbons may lead to still not well-known environmental consequences such as ground deformation and induced/triggered seismicity. Identifying and characterizing these effects is fundamental for
These examples show that SaLSA can consistently outperform the other models, possibly because of its non-empirical nature. However, we are unable to comment on the origin or the physical feasibility of such discontinuity of the V-Q curve, and further probing and refinement of models are required...
