The State of Health (SOH) lithium-ion batteries is a critical parameter that characterizes their actual lifespan, and its accurate assessment ensures the safe reliable operation batteries. However, in practical applications, SOH cannot be directly measured. To further improve accuracy estimation for batteries, this study employs Particle Swarm Optimization (PSO) algorithm to search optimal hyperparameters Bidirectional Gated Recurrent Unit (Bi GRU) neural network, enabling prediction time...

With the increasing burden of professional burnout in physicians, attention is being paid to optimizing sleep health, starting training. The multiple dimensions physicians’ are not well described due obstacles easily and reliably measuring sleep. This pilot study tested feasibility using commercial wearable devices completing manual logs describe patterns medical students residents. Prospective 50 resident physicians during a single year Participants completed log while concurrently wearing...

Modulating the electronic properties of transition metal dichalcogenides (TMDCs) by oxygen plasma treatment has attracted great attention. However, effect excitation power on oxidation and etching process in still lacks systematic investigation. In this work, optical microscopy, Raman photoluminescence spectroscopy, atomic force X-ray photoelectron spectroscopy (XPS) are used to characterize behaviors atomically thin MoS2 WSe2 nanosheets treated with different powers. The is a predominant...

Sketch maps are externalizations of cognitive which typically distorted, schematized, incomplete, and generalized. Processing spatial information from sketch automatically requires reliable formalizations not subject to schematization, distortion or other effects in maps. Based on previous empirical work, the authors identified different aspects such as ordering, topology orientation align integrate with metric qualitatively. This research addresses question how these qualitative can be...

Abstract This study combined various non-invasive and micro-invasive analytical techniques to investigate the production process of coffin plank paintings excavated from a Northern Wei tomb in Zhijiabao Village, Datong City, Shanxi Province. Fiber-optic reflectance spectroscopy, portable Raman X-ray fluorescence spectroscopy were employed for in-situ detection panel paintings. On that basis, micro-samples smaller amounts than previous studies same type collected analyzed through optical...

Gasoline particulate filters (GPF) are becoming a standard technology in gasoline engines because of the need for compliance with matter (PM) emissions requirement. Generally, GPFs can be placed after three-way catalysts (TWC) same can, or separate downstream. As typical wall-flow filters, is removed from exhaust by physical filtration using honeycomb structure similar to an catalyst substrate but channels blocked at alternate ends. The goal work was study efficiency and regeneration...

Compared with conventional vehicles, in-wheel drive electric vehicles (EVs) have many advantages like multi-degree of freedom (DOF) control system, high efficiency and driving stability. Varieties torque distribution strategies been proposed, but there is hardly any research focusing on the problem tire wear which has a large effect vehicle's economy particulate matter (PM) emission. In this article, an optimized algorithm aiming at reducing proposed. Joint simulation conducted between...

Diaphragm walls have been widely applied in long-span suspension bridges due to superior mechanical performance and extensive adaptability various geological conditions. However, limited studies focused on the structural behaviour of rigid joints for diaphragm walls. This paper hence presented flexural through experimental investigation numerical analysis. Two types were designed compare response terms failure modes moment resistance. Parametric analysis was carried out explore critical...

Abstract The paper summarises a series of investigations conducted in recent years at the University Sydney on behaviour and design stainless steel‐concrete composite structures, with focus mechanical performance beams, columns, joints. Three steel grades were considered experiments, namely austenitic, duplex, lean duplex. Details experiments as well some experimental observations are presented herein, along comparison test results simulations. also compared requirements predictions...

Abstract Polymers have played a vital part in the development of drug delivery systems (DDS). For DDS, having controllable diameter and distribution are conducive to reproducibility release behavior efficacy. In this work, an ibuprofen prodrug (Ibu@PMMA) was synthesized by methyl methacrylate (MMA), monomer (Ibu@HEMA), ethylene glycol dimethacrylate (EGDMA) via emulsion polymerization. The Ibu@PMMA exhibits spherical shapes, its structural properties were characterized NMR, FTIR, SEM...

Abstract The softening point of evaporation residue ordinary emulsified asphalt is low, which adhered to the wheel during construction and cannot play role interlayer bonding. author prepared Trackless tack coat materials by base with higher modifier improved high temperature performance, thus improved. Its physical chemical properties were analyzed compared two kinds asphalt. Under condition that remain unchanged, it has obvious effect non-sticking wheel. interlaminar shear pull-out tests...

The discrepancy between real-world and certificated NOx emission levels makes it very crucial for in-use surveillance. Therefore, investigating the characteristics of vehicles which have much higher emissions (i.e., high-emitters) determining a reasonable cut-off point with low false detection rate is important. In this study, six diesel trucks were tested under different aftertreatment conditions. results showed that discrepancies fuel-specific functioning tampered selective catalytic...

In this paper, optical microscopy (OM), scanning electron - energy dispersive spectroscopy (SEM-EDS), Fourier transform infrared (FTIR), Raman (RS), X-ray diffraction (XRD) were used to analyze the lacquered screen excavated from Sima Jinlong’s Tomb. The results show that comprises wood body, a lacquer ash layer, fabric another primer red and pigment layer inside outside. yellow is orpiment, black carbon black, white gypsum, green color mixture of indigo, cinnabar, which very rare in...

The wide use of Li-ion batteries in various industrial applications has led to a focus on their health status. This paper proposes novel fast SOH estimation method by combining the response characteristics and Genetic Algorithm-Extreme Learning Machine (GA-ELM) model. Based theoretical manipulations, dynamic due inrush current been derived shows that curve contains information related battery SOH.
