In this study, the effect of moisture content and density panel on some physical mechanical properties fiberboard was investigated. The differences were aimed to be revealed. test samples obtained from fiberboards which divided into three different (0.590 g/cm3, 630 g/cm3 0.680 g/cm3) contents (6%, 9% 12%) groups. Within scope such as water absorption thickness swelling bending strength, modulu...

The dynamic viscoelasticity of full-size wood composite panels (WCPs) under the free-free vibrational state were determined by a vibration testing method. Vibration detection tests were performed on 194 pieces of three types of full-size WCPs (particleboard, medium density fiberboard, and plywood (PW)). The dynamic viscoelasticity from smaller specimens cut from the panels was measured using a ...

This work presents a cyber-physical drilling machine that incorporates technologies discovered in the fourth industrial revolution. The is designed to realize its state by detecting whether it hits or breaks through workpiece, without need for additional sensors apart from position sensor. Such self-recognition enables adapt and shift controllers handle position, velocity, force, based on workp...

Focusing on convective heat transfer modelling upward flame spread scenarios, different methods for calculating the fluxes are explored. These approaches involve: 1) based stagnant film theory; 2) using a simplified approach 3) Nusselt correlations natural convection; and 4) convection effective (i.e., laminar plus sgs) thermal diffusivity. Large eddy simulations (LES) of series Single Burning ...
