Abstract: This research proposes a stacking machine learning method to accurately predict the compressive strength of recycled concrete. The model integrates eXtreme Gradient Boosting (XGBoost), Extra ...
The prediction of concrete compressive strength (CS, MPa) is fundamental in experimental civil engineering, as it enables the optimization of mix design and complements laboratory testing through ...
Decision follows China's expansion of nuclear stockpile Kremlin reacts cautiously to Trump's nuclear remarks Russia's recent nuclear tests include Poseidon super torpedo Pentagon expects Chinese ...
Geopolymers (GPs) are inorganic binders synthesised from reactive aluminosilicate materials such as metakaolin, fly ash, and blast furnace slag, using strongly alkaline solutions at room temperature.
Portafilter fit is a bit iffy. Grind settings are a bit floaty. Direct-to-consumer machines require a lot of faith on long-term maintenance. Grind assist is mostly theoretical at the moment. In theory ...
In the current environment of shifting tariff rates and ongoing trade deal negotiations between the United States and other countries, businesses continue to struggle to figure out how to preserve ...
As global wealth inequality deepens and automation threatens to usher in a new form of technology-driven unemployment, many nations, from the wealthy and industrialized to the still-developing, are ...
Some senior officials who have taken the test have been asked whether they said anything negative about the F.B.I. director, Kash Patel. By Adam Goldman Reporting from Washington Typically, the F.B.I.
A universal testing machine (UTM) can carry out a broad spectrum of tests, applying tensile and compression forces and assessing the test specimen’s load-displacement response. A key component of the ...
The study investigates the cyclic bond behavior of FRP bars from four key parameters—bar diameter, embedment length, concrete strength, and rib geometry—leading to the development of a unified bond ...
The amount of electronic content in passenger cars is growing rapidly, primarily due to the integration of advanced safety features. The shift towards fully autonomous vehicles, which must comply with ...
