Pneumatic systems are clean and reliable actuators, presenting very high force to weight ratios. They further present some advantages, such as inherent compliance and suitability for fire hazard environments. However, their intrinsic nonlinearities h

Depth control is crucial for underwater vehicles, not only to perform certain tasks that require the vehicle to be still at a given depth but also because most propeller-driven vehicles waste a considerable amount of energy to counteract the passivel

Abstract The literature that links career development with reading skills is scarce. This study seeks to fill this gap, for which the reading fluency of college students was analyzed, taking into account the choice of more/less desirable courses. Des

There are several compelling reasons for exploring the ocean, for instance, the potential for accessing valuable resources, such as energy and minerals; establishing sovereignty; and addressing environmental issues. As a result, the scientific commun

Pneumatic linear peristaltic actuators can offer some potential advantages when compared with conventional ones. The low cost, virtually unlimited stroke and easy implementation of curved motion profiles are among those benefits. On the downside, the
