Abstract Rice, as a primary commodity, needs to be increased in production while facing the sustainability challenges of limited land, water resources, and climate change. The demand for rice productivity was not enough to rely only on the fertile fields’ ability; it is necessary to consider the rainfed land potential. Cultivation in rainfed land involves biophysical pressure, low production, and limited access to superior varieties. Participatory rice breeding aimed to identify farmers’ trait preferences and develop acceptable lines. A bottom-up approach involved 203 farmers from four rainfed fields in Indonesia, i.e., Semarang-Central Java, Kulon Progo-Yogyakarta, Tabanan-Bali,… More >

Abstract In recent years, with the rapid development of software systems, the continuous expansion of software scale and the increasing complexity of systems have led to the emergence of a growing number of software metrics. Defect prediction methods based on software metric elements highly rely on software metric data. However, redundant software metric data is not conducive to efficient defect prediction, posing severe challenges to current software defect prediction tasks. To address these issues, this paper focuses on the rational clustering of software metric data. Firstly, multiple software projects are evaluated to determine the preset number… More >

Abstract Accurate Global Horizontal Irradiance (GHI) forecasting has become vital for successfully integrating solar energy into the electrical grid because of the expanding demand for green power and the worldwide shift favouring green energy resources. Particularly considering the implications of the aggressive GHG emission targets, accurate GHI forecasting has become vital for developing, designing, and operational managing solar energy systems. This research presented the core concepts of modelling and performance analysis of the application of various forecasting models such as ARIMA (Autoregressive Integrated Moving Average), Elaman NN (Elman Neural Network), RBFN (Radial Basis Function Neural Network),… More >

Abstract In order to reduce the ecological environmental pollution and economic losses caused by oil spill accidents from cross-river oil pipelines, this paper studies the structures of oil containment booms used for intercepting oil spills in rapid rivers and proposes a new type of double-layer hole oil containment boom. By establishing a solid mechanics model, the geometric deformation and stress-strain distribution patterns of the double-layer hole oil containment boom under rapid flow velocities were analyzed. Additionally, the impact of the skirt angle, hole size, and porosity on the mechanical properties of the new oil containment boom More >

Abstract Microbial polysaccharides, due to their unique physicochemical properties, have been shown to effectively enhance the stability of foam fracturing fluids. However, the combined application of microbial polysaccharides and surfactants under high-temperature and high-salinity conditions remain poorly understood. In this study, we innovatively investigate this problem with a particular focus on foam stabilization mechanisms. By employing the Waring blender method, the optimal surfactant-microbial polysaccharide blends are identified, and the foam stability, rheological properties, and decay behavior in different systems under varying conditions are systematically analyzed for the first time. The results reveal that microbial polysaccharides significantly More >

Abstract With the widespread use of polyethylene (PE) materials in gas pipelines, the problem related to the aging of these pipes has attracted increasing attention. Especially under complex environmental conditions involving temperature, humidity, and pressure changes, PE pipes are prone to oxidative degradation, which adversely affects their performance and service life. This study investigates the aging behavior of PE pipes used for gas transport under the combined effects of temperature (ranging from 80°C to 110°C) and pressure (0, 0.1, 0.2, and 0.3 MPa). By assessing the characteristics and thermal stability of the aged pipes, relevant efforts… More >

Abstract Climate change, rising fuel prices, and fuel security are some challenges that have emerged and have grown worldwide. Therefore, to overcome these obstacles, highly efficient thermodynamic devices and heat recovery systems must be introduced. According to reports, much industrial waste heat is lost as flue gas from boilers, heating plants, etc. The primary objective of this study is to investigate and compare unary (Al₂O₃) thermodynamically, binary with three different combinations of nanoparticles namely (Al₂O₃ + TiO₂, TiO₂ + ZnO, Al₂O₃ + ZnO) and ternary (Al₂O₃ + TiO₂ + ZnO) as a heat transfer fluid.

Abstract High-efficiency solar energy systems are characterized by their designs, which primarily rely on effective concentration and conversion methods of solar radiation. Evaluation of the performance enhancement of flat plate solar collectors by integration with thermal energy storage could be achieved through simulation of proposed designs. The work aims to analyze a new solar collector integrated with a porous medium and shell and coiled tube heat exchanger. The heat transfer enhancement was investigated by varying the geometrical parameters in shell and helically coiled tubes operating with CuFe₂O₄/water with different volume fractions of 0.02%, 0.05%, and 0.1 vol.%.… More >

Abstract The ongoing operation of subway systems makes existing tunnels vulnerable to deformations and structural damage caused by adjacent foundation pit construction. Such deformations-manifesting as horizontal displacement, heightened lateral convergence, and internal force redistribution-may significantly compromise subway operational safety. Grouting remediation has become a widely adopted solution for tunnel deformation control and structural reinforcement. Developing optimized grouting materials is crucial for improving remediation effectiveness, ensuring structural integrity, and maintaining uninterrupted subway operations. This investigation explores the substitution of fine mortar aggregates with 0.1 mm discarded rubber particles at varying concentrations (0%, 3%, 6%, 9%, 12%, and More >

Abstract The fixed-setting face-milled curvilinear cylindrical gear features teeth that are arc-shaped along the longitudinal direction. Some researchers hypothesize that this arc-tooth may enhance the lubrication conditions of the gear. This study focuses on this type of gear, employing both finite element analysis (FEA) and analytical methods to determine the input parameters required for elastohydrodynamic lubrication (EHL) analysis. The effects of assembly errors, tooth surface modifications, load, and face-milling cutter radius on the lubrication performance of these gears are systematically investigated. The finite element model (FEM) of the gear pair is utilized to calculate the coordinates… More >
