Inadequate sitting posture can cause imbalanced loading on the spine and result in abnormal spinal pressure, which serves as main risk factor contributing to irreversible chronic deformity. Therefore, recognition is important for understanding people’s behaviors correcting inadequate postures. Recently, wearable devices embedded with microelectromechanical systems (MEMs) sensors, such inertial ...

A thin liquid film subject to a temperature gradient undergoes thermocapillary convection because of the non-uniform surface tension at the free surface. This induced flow perturbs the film free surface and generate a free surface velocity field. These observable consequences can be thought of as the “signature” of the imposed temperature field and this work investigates whether the temperature...

Environmental philosophers spend considerable time drawing the divide between humans and the rest of nature. Some argue that humans and our actions are unnatural. Others allow that humans are natural, but maintain that humans are nevertheless distinct. The motivation for distinguishing humans from the rest of nature is the desire to determine what aspects of the environment should be preserved....
