Mechanical computation outperforms electrical in applications under extreme conditions. Currently, logic gates can be constructed with mechanical metamaterials, but this may require complex architectures and computing rules, more computations based on these are considerably challenging. systems multistability cannot return to their initial stable states, which hardly reused. Moreover, providing digital outputs is useful communicate systems. To address issues, metamaterials integrated a...

The excellent overall performance of polyoxymethylene (POM) fiber enables it to show great potential for engineering applications. effect POM fibers on the dynamic compression mechanical properties concrete is an important issue its application in structures such as airport pavement and bridges. It necessary investigate compressive POM-fiber-reinforced (PFRC) under impact loading. PFRC specimens with various lengths (6, 8, 12, 16, 24 mm) ordinary-performance (OPC) were tested by utilizing...

Recently, autonomous driving development ignited competition among car makers and technical corporations. Low-level automation cars are already commercially available. But high automated vehicles where the vehicle drives by itself without human monitoring is still at infancy. Such (AVs) rely on computing system in to interpret environment make decisions. Therefore, design essential particularly enhancing attainment of safety. However, our knowledge, no clear guideline exists so far regarding...

Recently, autonomous driving ignited competitions among car makers and technical corporations. Low-level vehicles are already commercially available. However, high where the vehicle drives by itself without human monitoring is still at infancy. Such (AVs) fully rely on computing system in to perceive environment make decisions. In AV systems, latency an essential metric for ensuring efficiency safety, because a timely decision with low will avoid accidents save lives. Moreover, we perform...

Abstract In the actual operation of a 300 MW boiler, there are some problems such as unstable combustion, high combustible material fly ash and slag, large thermal deviation on both sides steam. The Cooper method is used to divide three parts furnace by hexahedral structured grid, which can reduce grid number improve numerical simulation calculation precision. Realization k-ε turbulent model simulate gas-solid two-phase flow in before after reconstruction. boundary adopts operating...

The hot blast distribution has a great effect on the smooth operation of furnace (BF). standard deviation volume every tuyere (SD-BVT) is generally considered as an indicator for evaluating uniformity distribution. Based simulation, under condition that all tuyeres have same diameter, four circumferential symmetrical areas with large appear at 0, 90, 180 and 270 deg in Ansteel No. 1 BF, value SD-BVT 1.32. In order to improve distribution, diameter largest these reduced by 5 mm actual...

Current research on aluminum alloy gusset joints has neglected the influences of angle between members and curvature joint plate performance. This study introduces concept planar establishes 16 models using ABAQUS finite element software with parameters such as angle, arch angles, thickness, web flange thickness. The load-bearing capacity novel is theoretically analyzed, concepts strong weak axes are proposed. failure modes significance different regarding bearing initial stiffness under...

Abstract In this paper, the effect of WCp particle content (3 and 15 vol.%) laminate orientation on mechanical behavior laminated Cu/WCp/15p Cu/WCp/3p composites under dynamic impact was investigated using split Hopkinson pressure bar (SHPB) test. Subsequently, micro-damage evolution mechanism observed by scanning electron microscopy (SEM) optical microscopy. The results demonstrated that Cu/WCp are strain-rate-sensitive, a significant reinforcing composite properties observed. Furthermore,...

Ceramic membrane has made rapid progress in industrial/municipal wastewater treatment and drinking water owing to its advantageous properties over conventional polymeric membrane. The ceramic processes are a rapidly emerging technology for treatment, yet virtually no information on the performance fouling mechanisms diatomite In this study, filtration experiments were carried out using mixture of humic acid kaolin which simulated surface under constant pressure reveal characteristics results...

Compressed sensing theory is a subversion of the traditional theory. The main content this thesis reconstruction algorithm. It’s key compressed theory, which directly determines quality reconstructed signal, speed and application effect. In paper, we have studied existing algorithms. On basis summarizing algorithms models, analyze results such as PSNR, relative error, matching ratio running time them from image signal respectively. convergence CoSaMP algorithm faster than that OMP...

The problem of glaze coating spraying is one the problems faced in production practice. Uniform can greatly improve quality and aesthetic degree ceramics, so how to spray evenly has become an important research object. For material with smooth surface, we analyzed situation gun on single point line, drew a determined translation distance interval according actual needs, calculated best by enumeration method. obviously calculation formula for plane not applicable use projection principle,...

In the actual operation of 130t/h boiler in a power plant, due to unstable coal quality, there are some problems such as serious clinker formation water-cooling wall area furnace, ignition and poor combustion stability. The $\mathrm{k}-\Omega$ turbulence model is used for numerical simulation horizontal thick-thin burners. ratio concentration thick thin pulverized about 1.5, flow direction powder can be controlled by burner technology, which improve furnace. conditions furnace before after...

The quality of traffic data collected by detectors for open highways is easily affected bad weather and road construction, so the needs to be evaluated. Considering that macroscopic evaluation method requires a long period, leading ineffective, abnormal detection, this paper proposes combining online with offline quality. indices include threshold volume, speed, occupancy, consistent relationships among parameters are proposed practical engineering applications; while consist volume daily...
