This paper aims to present a robust environmental features recognition system (EFRS) for lower limb prosthesis, which can assist the control of prosthesis by predicting locomotion modes amputees and estimating in following steps. A depth sensor an inertial measurement unit are combined stabilize point cloud environments. Subsequently, 2D is extracted from origin 3D classified through neural network. Environmental features, including slope road, width, height stair, were also estimated via...
Coupling adjacent buildings using discrete viscoelastic dampers for control of response to low and moderate seismic events is investigated in this paper. The complex modal superposition method first used determine dynamic characteristics, mainly damping ratio frequency, damper-linked linear practical use. Random linked by then determined a combination the pseudo-excitation method. This combined can effectively accurately random non-classically damped systems frequency domain. Parametric...
A three-dimensional dynamic finite element model is established for the Tsing Ma long suspension Bridge in Hong Kong. The two bridge towers made up of reinforced concrete are modeled by Timoshenko beam elements with rigid arms at connections between columns and beams. cables suspenders cable accounting geometric nonlinearity due to tension. hybrid steel deck represented a single equivalent cross-sectional properties determined detailed analyses sectional models. modal analysis then performed...
Searching for a method low-cost, easily manageable, and scalable production of boron nitride nanosheets (BNNSs) exploring their novel applications are highly important. For the first time we demonstrate that effective hydrodynamics method, which involves multiple exfoliation mechanisms thus leads to much higher yield efficiency, can realize large-scale BNNSs. The fluid dynamics events contribute towards normal lateral processes could be applied other layered materials. Up ∼95% prepared BNNSs...
Soil aggregates are the basic units of soil structure, and their stability is a key indicator quality capacity to support ecosystem functions. The impacts various environmental factors on have been widely studied. However, there remains elusive knowledge synergistic effects changing forest stand structure aggregate (SAS), particularly in subtropical China where erosion critical issue. We investigated variations components humus (HS), including humic acids (HAs), fulvic (FAs), humins (HMs),...
Karst areas are sensitive to environmental changes due their fragile ecological environments. It is imperative explore the temporal and spatial variations in characteristics of vegetation net primary productivity (NPP) evaluate influence different driving factors on NPP. Taking three karst provinces southwest China as study area, where historical mechanisms influencing these remain unclear; therefore, present used NPP data from 1981 2019 analyze using slope trend analyses sequential...
Powered prostheses are effective for helping amputees walk on level ground, but these devices inconvenient to use in complex environments.Prostheses need understand the motion intent of help them environments.Recently, researchers have found that they can vision sensors classify environments and predict amputees.Previous accurately offline analysis, neglect decrease corresponding time delay.To increase accuracy delay environmental classification, we propose a new decision fusion method this...
Mapping the distribution and persistence of surface water in a timely fashion has broad value for tracking dynamic events like flooding, monitoring effects climate human activities on natural resource values biodiversity. Traditionally, is mapped from optical imagery using semi-automatic approaches. However, this process time-consuming accuracy results can vary among image interpreters. In recent years, Synthetic Aperture Radar (SAR) images have been increasingly used. Microwave signals...
The purpose of this study is to reveal the spatial-temporal change and driving factors green space in coastal cities southeast China over past 20 years. A supervised classification method combining support vector machines (SVMs) visual interpretation was used extract from Landsat TM/OLI imageries 2000–2020. landscape pattern index calculate geospatial information analyze their changes. hierarchical partitioning analysis then determine influences anthropogenic geographic environmental on...
Abstract This work compares various existing rough-wall models on a large collection of rough surfaces with different characteristics and studies the potential these in accommodating new datasets. We consider three empirical roughness correlations, two physics-based models, one data-driven machine-learning model 68 inside outside Roughness Database1. Results show that correlation-type do not extrapolate dataset against which they are calibrated or trained. In contrast, sheltering performs...
The mixing-layer analogy is due to Raupach, Finnigan & Brunet ( Boundary-Layer Meteorol. , vol. 25, 1996, pp. 351–382). In the analogy, flow in roughness sublayer of a homogeneous deep vegetation canopy boundary layer analogous plane mixing rather than surface layer. Evidence for includes inflected velocity profile, which resembles profile layer, and, most notably, following estimate as result Kelvin–Helmholtz instability: $\varLambda _x=8.1L_s$ where _x$ spacing large-scale eddies, and...
