Autonomous outdoor quad-rotor helicopters increasingly attract the attention of potential researchers. Several structures and configurations have been developed to allow 3D movements. The quadrotor helicopter is made of a rigid cross frame equipped with four rotors. The autonomous quad-rotor architecture has been chosen for this research for its low dimension, good manoeuvrability, simple mecha...

The Imaging X-ray Polarimetry Explorer is a mission dedicated to the measurement of polarization from tens astrophysical sources belonging different classes. Expected be launched at end 2021, payload comprises three mirrors and focal plane imaging polarimeters, latter being designed built in Italy. While calibration always an essential phase development high-energy space missions, for IXPE it h...

The cavitation response of circulating microbubbles to targeted ultrasound can be used for noninvasive, site-specific delivery of shell-loaded materials. One challenge for microbubble-mediated delivery of lipophilic compounds is the limitation of drug loading into the microbubble shell, which is commonly a single phospholipid monolayer. In this study, we investigated the use of natural lung sur...

Payload tracking maintains alignment between a payload and a target while both payload and target may be moving. This research investigates the generic problem of tracking from a mobile robot. A tracking strategy based on subsystem interactions is developed along with tools to model and evaluate payload tracking, metrics for evaluating tracking configurations , and guidelines for developing con...

The trend to minimize electronic devices also accounts for Unmanned Airborne Vehicles (UAVs) as well as for sensor technologies and imaging devices. Consequently, it is not surprising that UAVs are already part of our daily life and the current pace of development will increase civil applications. A well known and already wide spread example is the so called flying video game based on Parrot’s ...

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...

www.ijarcet.org 1866  Abstract— Spectrum scarcity is one of the most critical recent problems in the field of wireless communication. One of the promising approaches to resolve this issue is the use of Cognitive Radio technique. CR technique is performed by Secondary User (SU) to utilize the spectrums more efficiently. SU transmission mode can be broadly divided into two modes: interference av...

© 2012 ETRI Journal, Volume 34, Number 3, June 2012 A series of reversible watermarking technologies have been proposed to increase embedding capacity and the quality of the watermarked image simultaneously. The major skills include difference expansion, histogram shifting, and optimizing embedding order. In this paper, an accurate predictor is proposed to enhance the difference expansion. An e...

Locating steganographic payload using Weighted Stego-image (WS) residuals has been proven successful provided a large number of stego images are available. In this paper, we revisit this topic with two goals. First, we argue that it is a promising approach to locate payload by showing that in the ideal scenario where the cover images are available, the expected number of stego images needed to ...

Finding the full load motion for a point-to-point task can maximize the productivity and economic usage of the mobile manipulators. The presented paper proposes a technique to determine the maximum allowable dynamic payload for flexible mobile manipulators along with the obtained optimal trajectories. Non-linear modeling of the mobile robotic manipulators by considering both link and joint flex...
