The unique combination of lightweight, strength, corrosion resistance, high-temperature and biocompatibility make Ti6Al4V alloy an important material in metal contact solar cells, selective laser melting (SLM) enables the production parts complex geometries that would be difficult or impossible to produce using traditional manufacturing methods. build orientation SLM process presents essential effect on quality produced parts, thus, this study it investigates impact multi-build (0°, 30°,...
Significant economic losses, large affected populations, and serious environmental damage caused by recurrent natural disaster events (NDE) worldwide indicate insufficiency in emergency preparedness response. The barrier of full life cycle data preparation information support is one the main reasons. This paper adopts method integrated modeling, incorporates from existing event protocols, languages, models, analyzes observation demands different stages, forms abstract metamodel (FLCNDEM)...
This paper considers the problem of system parameter estimation using adaptive filter. Conventional algorithms will result in degraded performance presence impulsive noise and biased when input signal is noisy. To address these issues, this proposes a robust bias-compensated least mean squares (R-BC-LMS) algorithm. It derived by performing maximum- <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</b> -...
The thermal error modeling technology of computer numerical control (CNC) machine tools is the core compensation, and machining accuracy CNC can be improved effectively by high-precision prediction model errors. This paper analyzes several methods related to in latest research applications, summarizes their deficiencies, proposes a method tool based on particle swarm optimization (PSO) algorithm radial basis function (RBF) neural network, named as IPSO-RBFNN. By introducing compression...
This paper proposes a clustering-based downlink resource allocation (CDRA) algorithm for allocating spectrum resources in small cell networks. To improve the system capacity, proposed CDRA introduces clustering before allocation, and new method to divide all cells into set of clusters. Based on three principles, those that are adjacent each other grouped one cluster. After clustering, is performed macro based priority cell. The given higher than while depends size largest cluster it belongs...
This brief proposes a robust bias-compensated subband adaptive filtering (R-BC-SAF) algorithm for noisy input and large outliers. We first performs the maximum posteriori estimate subject to constraint on squared norm of weight vector difference in order obtain variable step-size method update combat An unbiasedness criterion is then employed insert bias compensation term reduce estimation caused by input. Besides, estimators are designed output noise variances. Simulations system...
Pink noise and spectral distortions affect the demodulation accuracies of fiber Bragg gratings (FBGs). A reduction algorithm with Savitzky-Golay filtering on each intrinsic mode function component decomposed by CEEMDAN, followed signal reconstruction from filtered components, is presented herein. Simulations show that retains FBG details while reducing noise, avoids measurement errors excessive smoothing, suppresses white pink noises adequately. resolution-enhanced peak detection distortion...
Light emitting diode (LED) is widely used in the field of optical communications because its low power consumption and high flicker frequency. Due to advantages consumption, many LEDs can be integrated into one array provide higher luminous intensity. In addition, combining light intensity with space coordinates utilized for positioning by unmanned aerial vehicle (UAV)-ground communication based on visible link. The precise LED an important factor UAV-ground communication. this paper, we...
