In Power-Factor-Correction (PFC) Boost Converter, due to the wide fluctuations of voltage as power frequency is 50 HZ, fast-scale instability and chaotic phenomena are apt appear in circuits. The method commonly used weaken unstable introduce slope compensation. However, since design signals lacks theoretical basis, overcompensation surfaces from time time, which leads substantial drop input factors. According this situation, we delay feeback control stabilize periodic tracks attractors....
Self-desiccation-induced shrinkage may result in cracking at an early age, which is averse to the durability of concrete. Internal curing (IC) agents, such as superabsorbent polymers (SAP), are normally used for moisture regulation and reduction. In addition, make-up recycled shale lightweight aggregate (RSLA) results a good absorbing capacity, makes it potential candidate IC. this paper, synergistic effect SAP RSLA on relative humidity (RH) variation early-age concrete under sealed...
In the active sound control problem, additional sources, known as are implemented at perimeter of a protected domain. The sources can generate secondary inside shielded domain, which attenuates incoming noise. This leads to an inverse source problem. Such problem becomes much more complicated if some desired is generated area. algorithm, nonlocal control, successfully tackles this due projection property operators involved. With application noise outside domain attenuated while internal...
In the active sound control problem considered, it is presumed that a bounded domain protected from external noise via distribution of sources on its perimeter. Moreover, generated inside interpreted as desired and supposed to be retained unaffected. We suppose only total field all primary secondary available for measurement at perimeter region. The approach based nonlocal has proved efficient tackle this problem. To make algorithm more feasible practical implementation, we minimize number...
Reconfigurable intelligent surface (RIS) is an emerging technology for wireless communications. In this paper, extensive system level simulations are conducted analyzing the performance of multi-RIS and multi-base stations (BS) scenarios, by considering typical settings industry standards. Pathloss large-scale fading taken into account when modeling RIS cascaded link direct link. The metrics downlink reference signal received power (RSRP) to interference noise ratio (SINR). evaluation...
The bending stiffness is a key quantity to determine mechanical behaviours, thermodynamical stability and even electronic transports of Graphene nanoribbons (GNRs). Using quantum mechanics lattice dynamics calculations, we characterise chirality width dependent GNRs. results show that, in the range (<1.6 nm) considered, out-of-plane zigzag graphene nanoribbon 17.5% larger than that armchair with same whereas their in-plane very close tend coincide an increase width. These trends are...
Abstract The underground environment in deep mines is complicated and the risk of rockburst high during excavation. Therefore, it great significance to study tendency At present, scholars from various countries have analyzed phenomena aspects strength, stiffness, energy, etc., proposed assumptions criteria. However, these criteria often only consider individual factors, which will lead one-sidedness limitations. This article takes mining process a metal mine as research background. Based on...
