The automation of agricultural machines is an irreversible trend considering the demand for improved productivity and lack labor in handling tasks. Unstructured working environments weather often inhibit a seemingly simple task from being fully autonomously performed. In this context, we propose remote driving system (RDS) to aid designed operate autonomously. Particularly, modify commercial sp...

The changing prices of bunker fuel open the door for substantial cost savings by adjusting the sailing speed of ships. A large ship may be burning up to 100 000 USD of bunker fuel per day, which may constitute more than 75% of its operating costs. Reducing the cruising speed by 20% reduces daily bunker consumption by 50%. However, in order to maintain liner service frequency and capacity, reduc...

The speed of the machine has to be increased from zero and brought to the operating speed. This is called starting of the motor. The operating speed itself should be varied as per the requirements of the load. This is called speed control. Finally, the running machine has to be brought to rest, by decelerating the same. This is called braking. The torque speed characteristics of the machine is ...

Frequency converters provide means for the energy efficient flow and pressure control in pumping and fan systems by varying the motor speed. Besides speed variation, a modern frequency converter can estimate the state and performance of system operation without additional measurement sensors. This ability provides several possibilities to optimize pumping or fan system operation and the resulti...

[Purpose] The purpose of this retrospective study was to determine the minimal clinically important difference for comfortable gait speed for patients with stroke. [Subjects] Data were analyzed from 35 patients undergoing inpatient rehabilitation. [Methods] Two characteristics of gait were measured, assistance required and comfortable gait speed. Patients were grouped as either experiencing or ...
