Abstract To facilitate high optical coupling efficiency and absorptance, the active area of a superconducting nano/microstrip single-photon detector (SNSPD/SMSPD) is often designed as meander configuration with filling factor (e.g. ⩾0.5). However, switching current ( I sw ) SNSPD/SMSPD, at which switches into normal state, significantly suppressed by geometry-induced ‘current crowding effect’, ...

a new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. we use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. then, we linearized this identified model at each sampling time to have an approximate linear time varying system. in order to stabilize...

Nowadays, flexible manufacturing systems play an effective role in a variety of production and timely response to the needs of their customers. Flexible manufacturing cell is a part of this system that includes machines with flexibility in manufacturing different parts. For many years, minimizing the number of tool switches in the machines has been studied by the researchers. Most research in t...

In a data center, servers communicate with each other to store and handle a large amount of data. Thus, the network within a data center affects the performance of the data center; the lack of bandwidth between servers increases the time to obtain the required data from the other servers. The energy consumption is also one of the important problems in a data center. The energy consumed by the d...

Abstract The miniaturization of ferroelectric devices offers prospects for non-volatile memories, low-power electrical switches and emerging technologies beyond existing Si-based integrated circuits. An class ferroelectrics is based on van der Waals (vdW) two-dimensional materials with potential nano-ferroelectrics. Here, we report semiconductor junctions (FSJs) in which the vdW ? -In 2 Se 3 em...

Abstract The ultrafast concentration of electromagnetic energy in nanoscale volumes is one the key features optical nanoantennas illuminated at their surface plasmon resonances. Here, we drive insulator to metal phase transition vanadium dioxide (VO 2 ) using a laser-induced pumping effect obtained by positioning single gold nanoantenna proximity VO thermochromic material. We explore how geomet...
