We present a class of efficient models called MobileNets for mobile and embedded vision applications. are based on streamlined architecture that uses depth-wise separable convolutions to build light weight deep neural networks. introduce two simple global hyper-parameters efficiently trade off between latency accuracy. These allow the model builder choose right sized their application constraints problem. extensive experiments resource accuracy tradeoffs show strong performance compared...
We present the next generation of MobileNets based on a combination complementary search techniques as well novel architecture design. MobileNetV3 is tuned to mobile phone CPUs through hardware-aware network (NAS) complemented by NetAdapt algorithm and then subsequently improved advances. This paper starts exploration how automated algorithms design can work together harness approaches improving overall state art. Through this process we create two new MobileNet models for release:...
A series of triaxial creep tests were carried out on fractured limestone specimens under multilevel loading and unloading cycles to capture elastoviscoplastic strain components. new data processing algorithm was proposed analyze the experimental data, determine instantaneous elastic plastic components viscoelastic viscoplastic from total strain, separate curves curve. The versus deviatoric stress relationships are highly nonlinear. proportion component in increases with increased stress. On...
This paper investigates fracture toughness and subcritical crack growth of marble, lherzolite, amphibolite under different environments aiming to better understand the effect environment, especially acidic solution, on fracturing behavior three rocks. Specifically, a series load relaxation (RLX) rapid loading tests were performed double-torsion (DT) specimens velocity V versus stress intensity factor KI relation evaluate KIC for studied rocks in air, distilled water, solutions with pH 6.0...
To better understand the shear behavior of infilled rock joints with standard joint roughness coefficient (JRC) profiles, direct experiments are performed on sand and clay prepared by reproducing JRC profiles a rock-like material placing infill inside joint. The results show that strength affected JRC, type, thickness to asperity amplitude (t/a) ratio, applied normal stress. For most joints, stress versus displacement curve shows residual value close peak no softening phase. pure compression...

Field investigations of high stress soft rock deformations show that the roadway can slide with large deformation. Severe extrusion and floor heave also be subsequently observed. The supported locally damaged or completely fail, where has a deformation and/or is seriously damaged. factors inducing surrounding rocks in deep are strengths, structure face cutting types, states, release, support patterns, construction methods. Based on characteristics roadway, comprehensive scheme proposed....
Food classification is a challenging problem due to the large number of categories, high visual similarity between different foods, as well lack datasets for training state-of-the-art deep models. Solving this will require advances in both computer vision models evaluating these In paper we focus on second aspect and introduce FoodX-251, dataset 251 fine-grained food categories with 158k images collected from web. We use 118k set provide human verified labels 40k that can be used validation...
Fine-grained recognition distinguishes among categories with subtle visual differences. In order to differentiate between these challenging categories, it is helpful leverage additional information. Geolocation a rich source of information that can be used improve fine-grained classification accuracy, but has been understudied. Our contributions this field are twofold. First, the best our knowledge, first paper which systematically examined various ways incorporating geolocation into image...
Taking a deep-mine horizontal roadway in inclined strata as our research object, the true triaxial simulation technique was used to establish model of and carry out high-stress loading experiments. The experimental results show that deformation surrounding rock presents heterogeneous characteristics time space: at different positions occurs times. In process rock, failure occur floor first, followed by lower shoulder-angle roadway, finally rest roadway. amount various areas is different....
Abstract In order to investigate the failure modes and instability mechanism of fractured rock. Uniaxial compression tests were conducted on sandstone specimens with different dip angles. Based rock energy dissipation theory fractal theory, evolution characteristics fragmentation in process deformation analyzed. The results show that peak strength elastic modulus mass are lower than those intact samples, both an exponential increase fracture angle. laws roughly similar can be classified into...
Abstract In order to examine the effect of spatial variation ground motion on response an indeterminate structure, stochastic responses a two‐span beam spatially varying support excitations are analysed. A space‐time earthquake model that accounts for both coherency decay and seismic wave propagation is used specify motions, results compared with those various simplified commonly in practice. The computed through linear random vibration approach structure being modelled by finite elements....
