Many factors affect short-term electric load, and the superposition of these leads to it being non-linear non-stationary. Separating different load components from original series can help improve accuracy prediction, but direct modeling predicting decomposed time will give rise multiple random errors increase workload prediction. This paper proposes a electricity forecasting model based on an empirical mode decomposition-gated recurrent unit (EMD-GRU) with feature selection (FS-EMD-GRU)....
Osteoarthritis (OA) is an age-related degenerative disease and the fourth major cause of disability, but there are no effective therapies because its complex pathology side effects drugs.
Abstract We designed a full-scale road piezoelectric energy harvester (FPEH) and performed field tests to evaluate its electrical performance under various traffic loads. Based on the open-circuit voltage waveform of FPEH, output characteristics were established given different axle loads vehicle speeds. New circuits that can be used identify wheel track position determine horizontal transfer vibration surface. Two off-board for applications FPEH. A parallel circuit rectifies 192 transducer...
Ensuring the accuracy of tunnel lining inspection instruments is crucial for maintaining safety. Given complexity and variability crack morphologies widths, it particularly important to conduct more in-depth verification measurement performance existing detection instruments. To this end, our study carefully crafted standardized simulated boards using rigid plastic restored by designing specific skeleton lines. These not only lay a solid foundation theoretically calculating widths but also...
In this paper, we optimized a multi-belt filter with ternary phase amplitude. Single and dual channel longitudinal magnetization needles were obtained by tight focusing azimuthally polarized sinh-Gaussian beam using the spiral plate in single-lens system. And chains same incident 4π The depth of focus transverse size was 64λ 0.36λ needles, respectively. For chains, DOF 60λ when normalized intensity within 0.8, there 43 spots range. 0.566λ each spots, addition, can move along z-axis linearly...
Vacuum preloading–electro-osmosis is one of the most useful ground improvement methods for soft soil but not widely used in practical engineering because its high power consumption and poor electro-osmotic efficiency later stages. To overcome these drawbacks, a new method – vacuum preloading with stepped-voltage electro-osmosis proposed this paper. Five laboratory tests were performed on dredged slurry. The results showed that an appropriate only better than general combined also requires...
In offshore engineering, the soft marine clay beneath an embankment may be subjected to anisotropic consolidation stress paths, which greatly affect its monotonic and post-cyclic shear behavior. this study, undrained behavior of anisotropically consolidated was investigated by conducting a series triaxial tests. First, behaviors, including stress–strain, pore water pressure, effective were comparing results Then, degradation strength analyzed. Finally, empirical prediction model anisotropy...
Abstract In the paper, a multi-belt complex phase filter was optimized by increasing number of belts and changing amplitude parameters filter. By focusing radially polarized sinh-Gaussian beams in single objective system with high-NA lens, longitudinal optical needles were obtained super-resolution focal plane. And needle owned 36.6 λ depth focus 0.42 full–width at half-maximum. The aspect ratio 87.14. beam quality reached to 87.7%. results demonstrated that can lengthen compress transverse...
In this study, a method of electrochemical consolidation is applied. This utilizes electro-osmosis, which an effective ground improvement technique for soft clays, and soil treatment using lime, the oldest traditional stabilizer. The mechanism lime involves cation exchange, leads to flocculation agglomeration. Five representative laboratory tests-an electro-osmotic test four tests with various proportions lime-were performed on dredged marine clay. objectives study are investigate effect...
Recently, submerged floating tunnels have generated a lot of interest due to their unique cross-water traffic benefits. However, the destructive threat submarine slide hazards was not fully considered in design scheme tunnels, particular feasibility applying various cross-section forms on land under that hazard influence. This study mainly investigates load effect with polygonal cross-sections (comprising three types: square, hexagon, and octagon) impact slides, via computational fluid...
This paper proposes a novel prescribed performance tracking control for hypersonic flight vehicle (HFV) with model uncertainties. Firstly, HFV longitudinal motion is decomposed into velocity subsystem and an altitude subsystem. Meanwhile, considering the uncertainties of model, are directly expressed as forms unknown nonaffine functions. Secondly, function without initial error proposed limiting range. Then, subsystem, objective changed by transformation backstepping controller designed. For...
AbstractGenerally, marine reclamation land needs to be improved by a large margin before the construction of civil structures in coastland due poor geotechnical properties dredged slurry.
