The floor area ratio for each block is extracted from the online map services (URASpace) by the Singapore planning authority (Fig. 5(c)). We use them to set the boundary conditions of our study. By doing so, we limit the variations of the input design variables within the development ...
Slip resistance is an important property of floor coverings essential for user safety. It is determined by the coefficient of friction. The coefficient of friction is the ratio of the tangential force and the vertical load of the sliding element when moving the sliding body on the surface. The ...
there was no mucosal ulceration. findings from the mr imaging study of the neck showed an approximately 2-cm, well-defined, ovoid, submucosal mass deep to the left oropharynx in the anterior parapharyngeal space. a second smaller lesion was seen in the left lower base of the tongue. a ...
Design of mass timber floor systems is commonly governed by vibration serviceability due to high stiffness-to-weight ratio and low inherent damping of timber. Research and design practice have shown that static deflection under a concentrated load and fundamental natural frequency can be effective and...
