The microstructure, distribution of the reinforcement, and phase changes were characterized using field emission scanning electron microscopy images and X-ray diffraction. The results indicate that the FSP route is an effective method for producing AA6063/Si3N4 nanocomposites which exhibit improved mechanical properties and wear resistance compared to the base material. Additionally, the corrosion resistance of the composite was found to be enhanced to that of the base material. In comparison with the base material, a significant improvement of 81% in hardness and 47.2% in tensile strength was observed in the 10% Si3N4 AMC.

In this study, a mathematical model was developed for the dynamic thermal analysis of ESCs designed for low and medium-temperature applications. Carbon dioxide (CO2), chosen as the working fluid in solar collectors, possesses several superior properties: excellent heat transfer capabilities, non-flammability, non-explosiveness, environmental friendliness, and low critical temperature and pressure. The developed mathematical model was validated against experimental results, demonstrating a deviation of 6.3% between theoretical predictions and experimental measurements. For the dynamic analyses, the seasonal and annual performances of the collector were assessed using meteorological data of Isparta, Türkiye. The calculated CO2 exit temperatures from the collector on specific dates (15 January, 15 April, 15 July, and 15 October) were 129.19 °C, 149 °C, 205 °C, and 170 °C, respectively. The maximum CO2 temperature was observed in July and June, whereas the minimum temperature occurred in January and December based on monthly average meteorological data.

Even today, on-line diagnosis of fluid power systems still remains a challenging task due to the computational cost and availability of machine operation data sets. For the prior, rapid fault diagnosis of the solenoid fault is of great economic values to the reduction in downtime maintenance. For the latter, currently the data for training networks are the major obstacles, as some of the rare faults are simply unavailable from the usual maintenance data. Facing the challenges, this paper presents a new way of quantifying the spool stiction severeness, a common fault in the solenoid on–off valves, using a proposed coupled physical model, where only temporal features from the solenoid coil driving current were extracted and applied for rapid diagnosis, without the need of spool displacement information. A test system was constructed in laboratory and different settings of valve spool stiction from normal to completely jammed were realized on the hardware. The developed coupled model is validated experimentally and demonstrates the capabilities in capturing the stiction effects. The quantitative diagnosis model based on temporal feature vectors was also tested and compared to the true stiction level, and the proposed sigmoid weightings have shown high prediction accuracy. The initial results have shown that the proposed model can quantify the spool stiction degree with accuracy at least 90% and with computation time less than 500 ms with a CPU at lower than 1.3 GHz.","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"62 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a novel turn-over intention method is proposed based on array air spring mattress. For this method, the turn-over intention of a lying patient can be recognized by identifying the internal pressure distribution of array air springs. To begin with, the samples of turn-over intention are created experimentally, and then input into a model combining Variational Auto-Encoder and Generative Adversarial Network for the sample augmentation to address issues related to low accuracy and poor generalization caused by sample imbalance. Besides, the augmented dataset is conveyed into the Convolutional Neural Network model, for the detection of three states: left/right turn-over intentions and no intention. The research demonstrates that, the similarity of the left and right turn-over intention samples generated by VAE-GAN model is 90.13% and 91.01%, respectively. This increases the diversity of samples and is helpful for intention recognition. The recognition accuracy of the CNN model with sample augmentation is 98.04%, which is 13.4% higher than without sample augmentation. The proposed method is effective to turn-over intention recognition, by identifying the internal pressure distribution of array air spring mattress.

Variety of characterization techniques like FTIR, XRD, Raman spectroscopy, dynamic light scattering and SEM–EDX, verified the successful synthesis of Cu3P NPs with spherical morphology. Three-electrode system containing glassy carbon, platinum mesh and Hg/HgO as working, counter and reference electrode, respectively, was used for the electrochemical characterization. Electrochemical studies, i.e., CV, LSV and chronoamperometric analysis, revealed efficiency and stability of electrocatalyst for electrolysis of water including hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Briefly, the Cu3P NPs exhibited an excellent OER activity, achieving the current density of 10 mA cm−2 with an overpotential of 450 mV. Tafel slope value 63 mV dec−1 suggested fast OER reaction kinetics. The Cu3P catalyst also exhibited significant HER activity, approaching a current density of 10 mA cm−2 with an overpotential of 447 mV.

A comprehensive mathematical model was developed to predict emission concentrations and simulate fuel mixture combustion using MATLAB Simulink software. This versatile model facilitates further analysis within the MATLAB ecosystem. The simulation results demonstrate a significant correlation between the hydrogen content in the natural gas mixture and the resulting heat power output. With a constant fuel consumption rate, a notable decrease in heat power was observed as the hydrogen concentration increased, reaching a maximum reduction of 44.9% at a 45% hydrogen content. These findings underscore the feasibility of partially substituting natural gas with hydrogen, while also highlighting the necessity for increased fuel flow rates to maintain equivalent power output levels. This poses additional challenges for natural gas grid operators, necessitating infrastructure adaptations to accommodate higher fuel demands.
