Autonomous lightweight flapping-wing robots show potential to become a safe and affordable solution for rapidly deploying around humans in complex environments. The absence of propellers makes such vehicles more resistant physical contact, permitting flight cluttered environments, collaborating with humans. Importantly, the provision thousands species birds that have already mastered challengin...

The position of the DC motor is controlled by using a continuous sliding mode control (SMC), which is highly robust to the Coulomb friction torque and to high unknown payload variations, which involve changes in the rotational inertia of the motor shaft. The main contribution of the work is the experimentation of a SMC control which does not requires the knowledge of the payload variation range...

A simple and inexpensive flight payload system for experimental high altitude balloon flights is described. The payload includes a simple 2m FM/CW telemetry beacon transmitter, an automated ID'er/controller which can provide up to 16 different CW telemetry status messages and also control an inexpensive digital camera for collecting still images at predetermined intervals during the balloon fli...

This memo describes an RTP payload format for the video coding standard ITU-T Recommendation H.265 and ISO/IEC International Standard 23008-2, both also known as High Efficiency Video Coding (HEVC) and developed by the Joint Collaborative Team on Video Coding (JCT-VC). The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload...

Various methods of determining the energetic performance of vehicles were described and compared. Earlier work emphasized maximum vehicle power and theoretical performance limits, and characterized the vehicle or payload in terms of weight. Energetic efficiency was calculated here as the payload mass times distance moved divided by thermal energy used. This efficiency was multiplied by average ...
