Abstract Sulfide‐based all‐solid‐state batteries (ASSBs) are widely recognized as one of the most promising next‐generation energy storage technologies. High‐mass‐loaded composite cathode is crucial for electrochemical performance ASSBs. However, safety characteristics practical cathodes have not been reported. Herein, thermal runaway mechanisms under different pressures systematically revealed by employing pellet pressing LiNi 0.8 Co 0.1 Mn O 2 (NCM811) and Li 6 PS 5 Cl (LPSC). Completely...
Abstract:
Abstract The primary circuit of a nuclear power plant contains steam generator (SG) and two vertical reactor coolant pumps (RCPs). Two RCPs are installed at the bottom SG. structure channel-head SG is special, which leads to uneven flow from RCP inlet affects operation performance pump. Taking third-generation as research object, unsteady characteristics under non-uniform inflow conditions were investigated using CFD, pressure pulsation inside mainly studied. A series monitoring points set...
In this paper, a cooperative guidance law based on consensus theory is proposed for multiple flight vehicles against maneuvering target in three‐dimensional plane. The has three orientation components: the one along line‐of‐sight (LOS) ensures that all reach simultaneously, and other two normal to LOS longitudinal lateral plane guarantee accurate interception. maneuverings are estimated by finite‐time convergence disturbance observer (FTDOB) compensated into kinematic equation achieve more...
ABSTRACT A novel second-order sliding-mode-based impact angle and autopilot lag guidance law for engaging manoeuvering targets with unknown acceleration is presented in this study. backstepping technique applied to the design of sliding surface. The proposed based on a new It exhibits advantage ensuring that surface its derivative will converge zero finite time while guaranteeing not cross until ultimate time. method effectively eliminates undesired chattering To compensate uncertainty...
Abstract This paper proposes an online entry trajectory planning based on predictor corrector algorithm that satisfies terminal constraints, path constraints and geographic for lifting-body vehicles. The vehicle is considered as a 3DOF point mass. A piecewise linear bank profile in the altitude-versus-velocity (H-V) plane used to project longitudinal heading angle corridor-based reversal logic designed satisfy simultaneously. solves problem of mismatch between range height lateral no-fly...
In recent years, micro attitude and heading reference system (AHRS) is widespread applied in aerospace, automotive to determine the of carrier as it low price, small size, light weight high reliability. This paper presents novel cost calibration methods for micro-electro-mechanical (MEMS) inertial/magnetic integrated sensors which are key unit AHRS. these methods, accelerometer magnetometer triads calibrated based on fact that norm accelerometers magnetometers outputs must equal gravity...
The New Culture Movement of the early twentieth century promoted vernacular literature to construct a close people. However, language was not used as an official for long time, resulting in its lack complex structure and ability express itself refined ways. With translation modern Western poetry, their preserved syntax gradually influenced creation new poems, poems Europeanized, with emergence many Europeanized syntactic features. Although this also resulted disadvantages strange lengthy...
Lyrical object, the one to whom lyrical subject epresses his feelings and emotions, plays a significant role in poems. “Airs of States”, oldest existing collection Chinese poetry, Shakespeare’s sonnets, representative classics traditions western lyric literature, show some similarities differences their choice different kinds objects. While most sentences States” are objective or first-person, second-person objects mostly used Sonnets. Therefore, effects caused. subtler gentler, Sonnets...
Abstract In this study, a new impact angle control guidance law is proposed against stationary target in the three-dimensional (3D) plane. A time-varying navigation gain derived to achieve specific terminal longitudinal plane without phased or adding bias term. proportional also adopted lateral an accurate strike. The monotonicity of look and convergence acceleration are analysed proven support method. For law, estimating time-to-go giving switch strategy unnecessary; continuous, which would...
A consensus theory-based distributed cooperative guidance law is proposed for multi-missile intercepting a non-maneuvering moving target in this paper. The model built on the three-dimensional plane. designed control method consists of three parts: part along line sight (LOS) guarantees salvo attacks all missiles, other two perpendicular to LOS vertical and lateral plane ensure zero angular rates achieve accurate interceptions. By applying Lyapunov stability theorem, convergences missiles¶...
With the increasing precision of guidance, impact autopilot dynamic characteristics and target maneuvering abilities on guidance is becoming more significant. In order to reduce or even eliminate operation influence, this paper suggests a system model involving novel integral sliding mode law (ISMGL). The method utilizes angle, combined with surface scheme that includes desired line-of- sight line-of-sight angular rate, second-order differential line-of-sight. At same time, evaluation...
Morphological filters can be used to eliminate the numerical instabilities in topology optimization results, including checkerboard patterns, mesh-dependence and intermediate densities. In this paper, two morphological filters, namely Type 1 2 are constructed according morphology-based restriction schemes. using Heaviside filter improved proposed by Sigmund and, Guest. The effects of kinds investigated, convergence, ability obtain discrete designs, iteration times compliances. Test results...
