levels. In the UK the generation of electricity emits 2.6 times as much carbon per watt when compared with burning natural gas. In terms of carbon emissions, therefore, a heat driven device with a COP of 2.5 would be equivalent to an electrically driven device with a COP of 2.5×2.6=6.5...
At present, the main direction of space energy collection and utilization is to collect, store, and convert heat energy and wind energy into electric energy by using in situ resources. In terms of thermal power conversion, Stirling has become a better way because of its high thermal power effi...
In terms of dynamic disasters, coal mine rock burst accidents have occurred more frequently in China in recent years, bringing huge pressure to safety production. The study of the mechanism of geotechnical engineering disasters is a fundamental work that can provide direction for subsequent monitoring...

Computational energy efficiency has become a primary decision criterion for most supercomputing centers. Data centers, once built, are capped in terms of the…
In the gas phase, this understanding is often based on the semi-classical three-step model (TSM)1 or its quantum mechanical extension2, which describes high-harmonic generation (HHG) in terms of a set of electron trajectories initiated by a tunnelling process. The results of this approach are...
we will use a simple example of RDK that is characterized by the fact that the energy-momentum composition law contains only nonlinear terms proportional to1/Λ, beingΛthe high-energy scale deforming the kinematics of SR. It can be seen [53] that such a model is an example of what is ...
In the wake of the rapid development of the Internet of Things (IoT) and artificial intelligence (AI) technology, a huge amount of wireless sensing nodes (WSNs) is urgently in demand in all aspects o...
frequency of 50 or 60 cycles per second (Hertz).Direct current (DC)elements are sometimes used to flow electricity between separate AC networks. Rectifiers are used to covert AC into DC and inverters are used to covert DC into AC. The amount of electricity a set of wires (referred to as...
We can normalize the global error measure in terms of the total energy in the system as Normalized Global Error Measure (16.3)η=|e|(|U|2+|e|2)1/2×100%where U is the strain energy contained in the finite element solution. The normalized global error can be interpreted as the percenta...
