The condition of the motor oil in civilian cars is difficult to monitor; hence, we propose a method evaluate degree degradation using an on-board diagnostic (OBD) system. Three and four oils (containing mineral synthetic oils) were subjected five groups road tests under urban traffic high-way conditions. operation information, service time, mileage, engine idle time engine, number start-ups obtained proposed OBD Physiochemical properties changes components during analyzed laboratory....
Separating induction motor noise sources can provide an important reference basis for condition detection, reduction treatment, and fault diagnosis. Induction motors have different types of that partially overlap, most radiate outward through the housing, so it is difficult to separate these sources. Therefore, a single-channel source separation identification method, based on adaptive scale-space modal extraction (ASSME) proposed. Firstly, mode method proposed by constructing...
The title compound, C16H16N2O4, contains two vanillin aromatic rings, which are bridged by a C=N—N=C unit. There half-molecules in the asymmetric unit; mid-points of N—N bonds lie on centres symmetry. molecular structure is stabilized intramolecular O—H⋯O and intermolecular O—H⋯N hydrogen bonds.
The title compound, (C8H18N2)[CoCl4], crystallizes with two cations, one complete anion and half-anions in the asymmetric unit, anions having twofold rotation symmetry. cation was obtained by methylation of DABCO (1,4-diazabicyclo[2.2.2]-octane). geometry [CoCl4]2− can be described as distorted tetrahedral. C—H⋯Cl hydrogen-bond interactions link cations crystal structure.
Abstract In order to study the degradation characteristics of special and nonspecific motor oil, two experimental vehicles carried out eight road tests with four types oils, which oils were for its engines recommended by OEM (original equipment manufacturer) other oil bought from market. Total acid number, oxidation stability, oxidation, nitration sulfation values analysed. The interpolation method Euclidean distance used evaluate similarity change curves properties. results show that onset...
Abstract Effective power system differentiation planning is crucial for enhancing the resilience of grid infrastructure and bolstering ability systems to manage blackouts. At heart lies core backbone planning. This study involves modeling as a multi-objective 0–1 problem, which enables formulation function that incorporates various factors such operational maintenance costs, significance nodes transmission lines, well compliance with connectivity security operation constraints. Moreover,...
Aiming at the teaching difficulties of signal and system course, adapting to new situation information age engineering education outcome-based (OBE), adhering traditional classroom making full use network platform internet technology, a blended mode internet-engineering (BTM-IEE) is proposed. In this mode, we adhered educational concept OBE, formulated objectives, optimized content, built matching resources. three stages: before class, in class after online-offline was effectively organized...
To enhance the node coverage of wireless sensor networks, a optimization method based on adaptive gold jackal is proposed. Firstly, nonlinear energy-decreasing control strategy proposed to balance exploitation and exploration. Then, grey wolf optimizer golden are mixed improve performance. Simulation results show that improved has higher convergence efficiency rate compared with traditional algorithm.
The title compound, (C8H18N2)[CuCl4], crystallizes with two cations and anions in the asymmetric unit. cation was obtained by methylation of 1,4-diazabicyclo[2.2.2]octane. C—H⋯Cl hydrogen-bonding interactions link to form an infinite three-dimensional network.
The reaction of m-fluorobenzoate silver with a self-assembling system ligand (Dabco = 1,4-diazabicyclo[2.2.2]octane) in an acetonitrile–water (2:1) solution (10 ml) afforded polymeric Ag(I) complex, {[Ag(H2O)(Dabco)1.5] [C7H4FO2]·2H2O}n, high yield. X-ray crystallography was used to investigate the resulting complex. coordination number around each is four, distorted tetrahedron geometry. Each cation coordinated by three nitrogen atoms from Dabco ligands and water oxygen atom. Two cations...
