Integration of Horizontal Light Pipe and Shading Systems in Office Building in the Tropics

open access: yesJournal of Applied Science and Engineering, 2021
Many high-rise office buildings in the tropics have a full-glazed façade and a deep open-plan space. Without any external shading, the office space has a non-uniform daylight distribution and glare problem.

Predicting the Instability Trajectory of an Obliquely Loaded Pipeline on a Clayey Seabed

open access: yesJournal of Marine Science and Engineering, 2022
Predicting the instability trajectory of an obliquely loaded pipeline on the seabed is vital for the global buckling assessment. To numerically investigate the obliquely loaded pipe–soil interactions, a plane strain elastoplastic finite element model ...

A low-frequency multiple-band sound insulator without blocking ventilation along a pipe

open access: yesScientific Reports, 2022
It is challenging to insulate sound transmission in low frequency-bands without blocking the air flow in a pipe. In this work, a small and light membrane-based cubic sound insulator is created to block acoustic waves in multiple low frequency-bands from ...
