Enhanced Geothermal System (EGS), as a key technology for the extraction and utilization of geothermal energy in deep strata and high temperature rock mass, has a broad application prospect in the field of energy. In order to understand the sustainable utilization capacity of the enhanced geothermal system, explore the influence law of different factors on the heat production capacity of geothermal Wells, and design a reasonable geothermal energy development and utilization program. The influence of different injection and production parameters on thermal recovery performance was studied by numerical simulation, and the main influencing factors were analyzed by orthogonal experiment. The results show that water injection rate has the greatest effect on the injection-production parameters, followed by well spacing and water injection temperature, and fracture opening and fracture number have the least effect. The optimal parameter combination is water injection rate of 10kg/s, well spacing 500m, water injection temperature 40℃, crack opening 0.09mm and crack number 60.

Hydraulic Portland cement, water, fine and coarse aggregate, and additional ingredients can be added or left out to create concrete. Making and maintaining concrete requires water as a reagent in the cement mixture so that a chemical reaction occurs when it undergoes the hydration process, which is the process where the cement begins to bind the ingredients that make up the concrete and then hardens and forms a solid mass. The need for water in concrete care is to soak it during the hardening process, however, not all types of water can be used. Peat swamp water is water that collects or flows within the peat swamp ecosystem. Peat swamps are a type of swamp formed from organic material accumulated over thousands of years. Silica fume is a material that contains SiO2 greater than 85% and is a very smooth, round material with a diameter of 1/100 the diameter of cement. The swamp water used in this research was taken from Jl. Rappokalling, Tallo District, Makassar City, South Sulawesi. Mix Design uses the Indonesian National Standard (SNI) 03-2834-2000 method with a planned concrete quality (f'c) of 25 MPa. Compressive strength tests were performed on concrete that was 7 and 28 days old for split tensile strength, and on the 28-day old concrete for modulus of elasticity. The concrete's compressive strength ratings after 28 days in variations of immersion in normal water and peat swamp water are 25,842 MPa and 20,749 MPa. From the test results, it was found that the average split tensile strength value of concrete for variations in normal water immersion and peat swamp water was 2.545 MPa and 1.886 MPa. From the results of the modulus of elasticity test, it was found that the average concrete in normal water immersion and peat swamp water variations was 19893.961 MPa, and 17109.75 MPa.

This research paper focuses on electric vehicle (EV) driving range and parameter estimation, with an emphasis on analyzing the New European Driving Cycle (NEDC) urban and suburban drive cycles. By examining these drive cycles, we obtain critical data on the moments when an electric vehicle transitions between constant velocity, acceleration, and deceleration phases, which significantly affect power consumption and driving range. We investigate various techniques for parameter estimation, including battery capacity, energy consumption rates, and powertrain efficiency, essential for improving EV performance and providing realistic range expectations. Empirical experiments in diverse driving conditions contribute valuable data to refine our understanding of EV driving range and performance in different scenarios. The research underscores the role of predictive modeling, data analytics, and advanced technologies in real-time parameter estimation, offering precise and convenient range predictions to enhance user confidence.
