This study was designed to evaluate the therapeutic effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on patients with refractory partial epilepsy.Sixty-four focal epilepsy were screened and 60 randomly divided into two groups by intensity: 90% (group 1) or 20% 2) resting motor threshold (rMT). Seizure frequency interictal EEG epileptic discharges compared between baseline follow-up periods.Seizures significantly decreased following 2-weeks high intensity (90% rMT)...
Composite materials have been widely used in recent years due to an attractive combination of superior physical properties. Since the macroscopic properties a composite material are determined by microscopic structure bottom layers, it is critical calculate elastic modulus single-layer plates using component material(s) scientific and effective manner. The traditional Halpin–Tsai model only considers two when calculating modulus. This paper proposes improved considering three-phase...
Lu'an, as one of the two major tea-producing areas in Anhui Province, has a long history tea planting and rich germplasm resources. However, genetic diversity population structure local plants are still unclear. In order to better protect utilize resources 217 accessions from six geographical origins were used assess Lu'an plant through double digest restriction-site associated DNA sequencing (ddRAD-seq) technology. A total 306,320 high quality single nucleotide polymorphism (SNP) markers...
System design of liquid rocket engines must consider engine performance, weight, cost, and reliability requirements. A general optimization framework has been developed in this paper to select the best system parameters for with gas-generator cycles. The object is maximize specific impulse vacuum thrust-to-weight ratio given requirements assumptions by changing thrust-chamber pressure mixture ratio. analysis, along weight estimation, based on a modular scheme. Multidisciplinary formulations...
Abstract Conventional energy harvesters often require high ambient vibration frequencies and can only capture in a single direction. To address these issues, this paper designs magnetostrictive two-dimensional kinetic harvester placed under the floor capable of capturing both vertical horizontal directions. In order to achieve higher electrical power output at low-frequency input forces, two-stage force amplification mechanism is designed amplify walking pedestrians main parameters structure...
The acoustic emission data collected during room temperature tensile test of 2D-C/SiC composites were analyzed by hierarchical clustering and unsupervised pattern recognition method based on an improved genetic algorithm.Combined with the SEM observation fracture surface, five damage modes identified their typical characteristics obtained.According to analysis energy distribution, cumulative event number different modes, evolution process C/SiC can be divided into four stages.The first stage...
Gas-dynamic resonance ignition is a new technology prospective in repetitive starting of future space vehicle. Based on the investigation structural and operational reliability for some schemes hydrogen oxygen ignition, novel type coaxial hydrogen/oxygen scheme was advised. By means more than 1000 times gas-dynamic heating mechanism tests, basic techniques have been successfully investigated, including characterization gas, verification annular injector nozzle resonating performance,...
The strong coupling effect of two-phase flow and ice accompanies the accretion process aircraft wind turbine in damp cold environment. A method based on Eulerian flow, domain discretization finite volume (FVM) element (FEM), fluid–solid for numerical simulation is presented this paper. In addition, icing two-dimensional (2D) airfoils investigated. It found that difference between results experimental data comes from phase changes local collection efficiency [Formula: see text], which a...
Tooth root bending fatigue performance is the primary consideration in gear design.

Aluminium alloy, as a commonly used material in modern aircraft structures, is susceptible to corrosion damage under the influence of high temperature, humidity, salt spray and other climatic conditions. Corrosion structure action fatigue loading will accelerate formation expansion cracks, shortening life material. In order accurately predict aluminium alloy different conditions, this paper collects data on material, environment, load crack rate expansion, establishes prediction model for by...
Acoustic emission (AE) is a non-destructive testing technique, and establishing correlations between AE signals material damage modes one of its primary challenges. However, it difficult to identify in ceramic matrix composites (CMCs) due signal attenuation occurring after propagation complex modes. In this study, generated by the breakage C SiC fibers were monitored at different distances angles on C/SiC plate. The energy frequency spectra analyzed. Mel-frequency cepstral coefficient (MFCC)...
