Linux container mechanism has attracted a lot of attention and is increasingly utilized to deploy industry applications. Though it consensus that the not secure due kernel-sharing property, lacks concrete systematical evaluation on its security using real world exploits. In this paper, we collect an attack dataset including 223 exploits are effective platform, classify them into different categories two-dimensional taxonomy. Then evaluate existing 88 typical filtered out from dataset. We...
ConspectusAtomically precise titanium-oxo clusters (TOCs) are the structure and reactivity model compounds of technically important TiO2 materials, which could help build structure-property relationships achieve property modulation at molecular level. However, traditional formation TOCs has relied on poorly controllable hydrolysis titanium alkoxide in solvent for a long time, limiting development TOC structural chemistry to great extent. In addition, easily hydrolyzable alkoxy groups would...
This study investigates nitrogen molecular radiation in hypersonic expanding flow around a two-dimensional model. Experiments were conducted using the JF-14 shock tunnel tube mode, generating 3.25 km/s wave to create required flow. A blunt model with 25-mm nose radius was used generate Spatially resolved visible spectra measured model's shoulder. Numerical simulations then analyze properties and spectral distributions. The results show that N2 first positive system dominates emissions...
Abstract No. 1262 Yan'an West Road and 60 Panyu in Shanghai were previously part of Columbia Circle, which began construction 1924, the base Institute Biological Products (SIBP) from 1951 to 2014. They have now been transformed through urban renewal into one Shanghai's famous instagrammable spots: Vanke Circle Park. In survey this completed site, we find that spatial traces collective living form danwei since SIBP era are almost invisible cultural landscape site. We use oral history...
With the continuous improvement of national medical system, health monitoring combined with cloud computing and Internet Things has become a concern. This study mainly discusses design IoT system based on computing. From user to service provider, there are three devices: sensor terminal, gateway platform. The terminal is used measure physiological indicators, such as blood pressure, electrocardiogram, oxygen saturation, heart rate, other indicators; link receive indicators forward them...
Purpose The purpose of this paper is to describe the development a contactless and batteryless loading sensor system that can measure internal an object structure through several covering materials for structural health monitoring. Design/methodology/approach proposed architecture by which two radio frequency identification (RFID) tags are used in system. It has been difficult realize sensing RFID because low power supply. To solve supply problem, method using functional distribution kinds...
Since the 2008 great Mw 7.9 Wenchuan earthquake, two destructive earthquakes, 2013 6.6 Lushan earthquake and 2017 6.5 Jiuzhaigou struck eastern margin of Tibetan Plateau, causing many casualties significant property damage. The rupture processes Coulomb stress change earthquakes are investigated in this study. general patterns slip models events similar, where is concentrated around hypocenter primary ruptured zone extends about 20 km along strike. spans a depth range 4–16 with peak ~ 115...
The mechanical and combustion properties of metal-nested composite hybrid rocket fuel grains composed spiral aluminium (Al) frameworks fabricated using three-dimensional (3D) printing with an embedded paraffin-based were investigated. the resulting evaluated by compression tests. In addition, characteristics Al examined in a lab-scale engine gaseous oxygen as oxidizer at initial mass flow rate 17.9 g/s. Pure (PP) acrylonitrile–butadiene-styrene (ABS) also tested baseline fuels for...
Precise prediction of aerothermal loads is significantly limited by the unclear interactions between thermal protection system surface and surrounding high-enthalpy gas. To address this, we propose an optical diagnostic method based on emission spectroscopy laser absorption to investigate gas–surface within boundary layer. Experiments are conducted in air plasma flow produced 1.2 MW inductively coupled wind tunnel at China Academy Aerospace Aerodynamics with enthalpy 20 MJ/kg a heating time...
The flame dynamics in the combustion chamber of a hybrid rocket motor were visualized using novel chemiluminescence imaging. A multidirectional visualization system employing [Formula: see text] endoscopes generated images based on methylidyne (CH*), with one endoscope precombustion and two postcombustion chamber. Images collected high-speed camera 1 ms exposure kHz frame rate. Fuel grains having helical or conventional circular port structures assessed, trials conducted laboratory-scale...
Abstract On 24 January 2020 (UTC), a destructive Mw 6.7 earthquake struck the east Anatolian fault of eastern Turkey after series foreshocks, causing many casualties and significant property damage. In this study, rupture process is investigated with teleseismic broadband body-wave surface-wave records. Results indicate that left-lateral strike-slip event, extends mainly to south. The main slip patch spreads ∼30 km along strike in shallow above 14 peak ∼1.2 m, total seismic moment 1.69×1019...
