Modern land seismic acquisition is known for its complexity in terms of the number of equipment utilized, logistics, labor intensity and often harsh weather conditions. To solve some challenges and supplement conventional seismic exploration procedures, such as near-surface characterization, seismic-while-drilling, acquisition infill, we developed...

Nowadays, there are few unmanned aerial vehicles (UAVs) that are capable of landing on uneven surfaces or moving on the complex ground. A drone having both of these functionalities can significantly improve its performance in accomplishing difficult tasks such as monitoring and exploring various types of terrain, searching for survivors, delivering...

Drone application for aerial manipulation is tested in such areas as industrial maintenance, supporting the rescuers in emergencies, and e-commerce. Most of such applications require teleoperation. The operator receives visual feedback from the camera installed on a robot arm or drone. As aerial manipulation requires delicate and precise motion of...

One of the most serious disadvantages of the Vertical Take-Off and Landing flying robots including multicopters is the necessity in the flat stable area for safe landing. The ability to land and take-off from uneven surfaces and moving basements would help the rotorcrafts in many important applications. The special landing gears are used to provide...

The measurement of blood pressure is an important cardiovascular health assessment, yet the current set of methodologies is limited in resolution, repeatability, accuracy, simplicity, and safety. This paper presents the design and prototype implementation of a novel and easy-to-use medical device for noninvasive and continuous blood pressure monito...

A fine-grained Ti–6Al–4V sheet that has been developed for superplastic forming (SPF) was joined to a standard Ti–6Al–4V sheet using a Nd:YAG laser and alloy compatible filler wire. The microstructural and mechanical properties of dissimilar laser beam welded butt joints were investigated to determine their behavior under static and cyclic loads an...
