The Junggar Basin contains widely distributed Jurassic low-rank coal seams (Badaowan Fm. J\(_1\)b, Xishanyao Fm. J\(_2\)x) with abundant coalbed methane (CBM) resources. Integrating proximate analysis, maceral identification, vitrinite reflectance, low-temperature N\(_2\) adsorption, high-pressure m...

This paper presents a simple and efficient method for detecting harmonics, interharmonics, and subharmonics in voltage and current waveforms. The proposed technique is based on a series RLC resonant circuit and is characterized by its simplicity, relatively fast response, and ease of implementation....

This study investigates the order and convergence properties of an extended two-point superclass Block Backward Differentiation Formula (BBDF) incorporating two intermediate (off-step) points for the numerical solution of stiff initial value problems (IVPs). Stiff systems frequently arise in scienti...

Geo-energy infrastructure—comprising oil and gas systems, CCUS, geothermal installations, and subsurface storage—is critical for energy security and low-carbon transitions. Yet disasters and engineering failures can trigger hazardous leaks and contaminant transport through complex geological media,...

Nanopores in shale are critical controls on shale gas storage and transport, and their formation, transformation, and preservation during geological evolution have long been major research topics in unconventional oil and gas geology. Considerable progress has been made in understanding the evolutio...

Agriculture plays a vital role in Nigeria’s food security and economy, yet crop productivity depends heavily on land suitability. This study assessed the suitability of land for arable crops in Ondo State using Geographic Information System (GIS) and Multi-Criteria Evaluation (MCE) techniques. Ninet...

The increasing digitization of modern society has led to a growing volume of digital information---such as emails, photos, videos, and electronic records---being presented as evidence in legal proceedings. However, traditional storage systems are costly, slow, and prone to server failures. To addres...

Engineering Economics is a core course for the Engineering Cost major in application-oriented undergraduate universities, yet traditional teaching often suffers from a theory-practice gap, low student participation, and polarized academic performance. Guided by Outcomes-Based Education (OBE), this s...

Operating rooms (ORs) account for a significant fraction of a hospital's energy footprint, yet traditional surgical scheduling models ignore the dynamic energy consumption of heating, ventilation, and air conditioning (HVAC) systems, particularly the thermal inertia and peak restart loads. Furthermo...

Taking notes during meetings sounds easy, but in reality, people often miss key points—especially when multiple people are talking. Managing follow-ups in separate apps only adds to the hassle. MinuteMaster was built to simplify this. It's a web app that brings transcription, speaker identification,...
