Recently, it has been demonstrated that the use of SnO2 as electron transport layer (ETL) perovskite (PSK) solar cells (PSCs) yields high efficiency, which is comparable to TiO2 with same structure. At time, SnO2-based PSCs show improved stability. Herein, defects at device interface are reduced and efficiency planar enhanced by improving contact between ETL layer. As an essential amino acid, tyrosine (Tyr) introduced into fill oxygen vacancies in films improve nucleation PSK. From our...

Recently, analog behaviors in resistive random-access memory (RRAM) have been proposed as a promising circuit implementation for neuromorphic computing. However, to date, there relatively few studies on the issue of resistance degradation (computing weight) induced by thermal disturbances high-density RRAM arrays. In this paper, simulations three-dimensional (3D) one-selector, one-resistor (1S1R) crossbar array computing were performed using COMSOL Multiphysics software. Four factors...

The tractor-trailer-train at the braking process prone to instability caused by asynchronous between shafts. With respect lack of intelligent detection Braking Time Sequence (BTS), a non-contact dynamic scheme vehicle BTS is proposed. Based on monocular vision principle, edge markers tractor-trailer train tires are identified, and tire slip rate solved. noise reduction collected image processed. marker area obtained Blob analysis. This region be matched identified template matching algorithm...

Using CuPc as the hole buffer material, effect of 2T-NATA and materials in similar structure on performance devices is studied. For this reason, ITO/CuPc (20 nm)/NPBX/DPVBi nm) (15 nm)/Alq3: Rubrene (10, X nm)/Alq3 (40 nm)/LIF/Al (5 light-emitting device designed. Referring to previous papers devices, best that thickness doped rubrene 20 nm. In paper, Alq3 doping 10 nm, adjusted 5 15 nm 25 selected at according experimental results. The results show when yellow light blue tend balance, close...

Recently, it has been demonstrated that the use of SnO 2 as electron transport layer (ETL) perovskite solar cells (PSCs) yields high efficiency, which is comparable to TiO with same structure. At time, -based PSCs show improved stability. Herein, defects at device interface are reduced and efficiency planar enhanced by improving contact between ETL (PSK) layer. As an essential amino acid, Tyrosine (Tyr), introduced into fill oxygen vacancies films improve nucleation PSK. From our analysis,...

Abstract In order to make the allocation of transmission and distribution costs more reasonable, cost models for different voltage levels based on postage stamp method peak load liability are constructed. Two used calculate compare in a power grid company. The results show that is reasonable than allocate among levels.

The complex assets management system under the global optimum is mainly aimed at current situation of Power Grid Company and realizes whole process lean from three aspects organizational structure, rules regulations integrated information platform with help full-service data center. This paper analyzes two aspects: target direction, functional characteristics.

The complex assets management system under the global optimum realizes whole process and lean of from three aspects organizational structure, rules regulations. This paper analyzes two time dimension space dimension, in order to ensure overall consideration control management.

A non-restrictive and non-inverse monitoring system for bio-information during sleep is developed. The structure of detection device used in this flat type, so it can be easily placed on the bed measurement human-being sleep. Also, there are no electrodes to pasted body when monitoring. Therefore, non-restrictive, unconscious realized, comfort improved. Performance experiment vivo carried out. Experimental results show that such as respiration, heart beat motion measured. At same time,...

This paper uses the theory of Interpretative Structural Modeling to select some key indicators from many that affect health assets, and builds a evaluation system for asset status data. When optimizing indicators: Firstly, calculate reachability matrix by constructing an adjacency matrix; Secondly, rearrange obtain size driving factor indicator; Again, index group achievement are used as screen, so it not only meets requirements screening indicators, but also reflects all indicator...

The complex assets management information system under the global optimum is mainly aimed at current situation of Power Grid Company and realizes whole process lean from three aspects organizational structure, rules regulations integrated platform with help full-service data center. This paper analyzes two aspects: pattern content subsystem.

The wind power has brought many problems to the grid. Among them, voltage stability problem is most prominent. main reason insufficient reactive power. In response above problems, this article first starts with farm itself, excavates generation ability of its own equipment, and conducts in-depth research on rotor-side inverter side inverters doubly-fed turbines were studied, mechanism participating in regulation was explored, optimal coordinated control strategy two proposed, software model...
