With the development of Electric Vehicles (EVs), Vehicle-to-Vehicle (V2V) electricity transactions have gained popularity. Among them, EV users can easily obtain information such as their own location and speed through Internet (IoV), communicate with other entities IoV, but leak transaction plan private identity, location, speed, etc. required for may put in danger undermine fairness transaction. Aiming at above problems, A V2V scheme privacy protection based on IoV consortium blockchain is...
This study used a two-stage method to derive an analytical solution for assessing the vertical displacement of existing pipeline caused by undercrossing construction shield tunnel. The aim was evaluate impact excavation on adjacent pipelines. A Timoshenko beam lying Vlasov foundation adopted model subjected soil disturbance induced underneath tunneling. considered shear stiffness and nonuniformity parameters. lateral action in force analysis develop prediction settlement. proposed tested...
The twin propeller system can be powered by a motor with dual-rotating rotors, which generally necessitates that both rotors run at the same speed to prevent rolling. is popular for applications benefit from high torque density and an axially compact form factor. In order minimize effects of load disturbances internal parameter perturbations on performance, this paper proposes control strategy combining disturbance observer sliding mode (SMC) technologies realize purpose rotating speed....
This study investigates the effect of ultraviolet (UV) illumination on corrosion resistance 304 stainless steel in molybdate-containing solution. The UV was found to reduce passivation and pitting passive films. In addition, film exhibited n-type semiconductor characteristics. Under illumination, content Cr2O3 within decreased. Moreover, formation a built-in electric field inhibited absorption MoO42− substrate surface, thereby weakening inhibition Na2MoO4. leads reduction film.
This paper proposes a novel parameterized frequency‐domain modal parameter identification method, called direct variational mode decomposition (DMVMD), based on the multivariate (MVMD) framework and principle of superposition. Under constraint normalized shapes, this theoretically derives relationship between natural frequencies shapes structural systems. The aim is to extract K response modes their corresponding from excited C‐dimensional vibration signals measured component’s response....
This article investigates the pitting resistance of a newly developed Fe-Cr-Mn-N austenitic stainless steel with 0.14 wt% carbon and its counterpart 0.02 carbon. By using especially hot-rolled bimetal specimens, we focus on behavior near interface between two alloys demonstrate that solid solution can significantly improve resistance. The alloyed increases passive film stability, but more fundamental reason is suppresses active dissolution rate matrix, thereby inhibiting kinetics growth....
Luteolin is a common flavonoid in plants and exhibits variety of biological activities. In this study, luteolin was reacted hot water with five trace metal elements found plants, the products were tested by electrospray-ionization time-of-flight mass spectrometry (ESI-TOF MS). formed complexes Ca2+, Mg2+, Zn2+ both 2:1 3:1 ratios, addition to complex Cu2+ ratio. A luteolin-iron (III) also ratio, small amount Fe2+ produced form (II) The luteolin-Cu2+ exhibited significant DNA cleavage...
Rutin, a flavonoid commonly present in natural plants, can form multiple complexes at different rutin : metal ratios with various trace elements during the water decoction process, and these exhibit novel activities.
The discovery of organic components with pharmacological activities in medicinal plants is crucial for new drug development. We examined chlorogenic acid (CGA) using high-performance liquid chromatography to analyze the aqueous and methanolic extracts dissolved methanol or containing 15% formic acid. found that extract, peak areas various were significantly larger than those methanol. For differences all chromatographic peaks relatively small between samples two solvents. Electrospray...
In response to the data anomalies and frequent false alarms caused by harsh environments in long‐term structural health monitoring (SHM), this study has reframed detection of abnormal vibration as a time series classification problem. This approach identifies multiple anomalous features, thereby reducing manual costs. The novel developed Convolutional Neural Network with Squeeze‐and‐Excitation Multi‐Head Self‐Attention (CNN–SE–MHSA) employs deep residual network structure channel spatial...
In this article we reveal that the optimal annealing temperature for 2205 differs between acidic and neutral NaCl environments, rendering limitation of utilizing pitting resistance equivalent number (PREN) to optimize temperature. Elevating leads a better corrosion ferrite phase in activation zone through Ni redistribution. systems, is co-governed by content PREN. This conclusion offers valuable guidance heat treatment process DSS be used environments.
The corrosion behavior of β-Sn and intermetallic compounds in Ag–28Sn alloy was investigated by potentiodynamic polarization bipolar electrochemistry tests. results show that the Na2SO4 solution Ag4Sn preferentially corrode at high potential low potential; NaCl solution, corrodes both potential. To clarify mechanism selective corrosion, an Ag–Sn coupled electrode assembled characterized using test. Based on potential–pH diagram, is elucidated.
