Error Control Coding for Digital Communication Systems Using BCH and Hamming Techniques

This study evaluates and compares the performance of Hamming and BCH error control coding techniques, demonstrating that while Hamming codes offer a computationally efficient solution for single-bit error correction, BCH codes provide superior capability for correcting multiple-bit errors in noisy digital communication channels.

Investigation on bearing capacity and settlement characteristics of square footings founded on geosynthetic-reinforced rubber–sand mixture

This study demonstrates through reduced-scale model tests that geocell reinforcement significantly enhances the bearing capacity and reduces settlement of square footings on rubber–sand mixtures, with optimal performance achieved through specific reinforcement depths and dimensions, particularly when using larger rubber granules that benefit from improved interlocking within the geocell apertures.

The thermal characteristics and performance indicators of energy-saving building envelope structures containing phase change materials

This study demonstrates that sandwich-type phase change gypsum boards, fabricated with a palmitic acid–lauric acid eutectic core, significantly enhance the thermal inertia and dynamic performance of building envelopes by effectively reducing temperature peaks, delaying heat transfer, and stabilizing indoor temperatures compared to ordinary gypsum boards.

Mechanical Deterioration and Micro-macro Damage Evolution Mechanisms of Underground Reservoir Coal-Pillar Dams Subjected to Drying-Wetting Cycles

This study reveals that drying-wetting cycles cause non-uniform, multi-stage mechanical degradation in coal pillar dams, primarily driven by the dissolution of hydrophilic minerals which transforms micropores into macropores and shifts the failure mode from micro-tensile cracking to macro-shear sliding, thereby compromising the structural stability of underground reservoirs.
