Energy Harvesting Technologies for Structural Health Monitoring of Airplane Components-A Review.

With the aim of increasing the efficiency of maintenance and fuel usage in airplanes, structural health monitoring (SHM) of critical composite structures is increasingly expected and required. The optimized usage of this concept is subject of intensive work in the framework of the EU COST Action CA18203 "Optimising Design for Inspection" (ODIN). In this context, a thorough review of a broad range of energy harvesting (EH) technologies to be potentially used as power sources for the acoustic emission and guided wave propagation sensors of the considered SHM systems, as well as for the respective data elaboration and wireless communication modules, is provided in this work.

Planar conformity of movements in 3D reaching tasks for persons with Multiple Sclerosis.

Robotic rehabilitation of the upper limb has been proved beneficial for people with Multiple Sclerosis (MS). In order to provide task-specific therapy for MS, given its complex impairing nature, it is desired to take advantage of the robots' ability to move and provide force feedback in generic three-dimensional motions. Previous investigations have shown that hand motion during reaching tasks is piecewise planar, therefore, it is possible to simplify the design of robotic rehabilitation trajectories by confining them on planes oriented in space.

Calculated reduction aortoplasty for dilatation of the ascending aorta associated with aortic valve replacement.

Background: Previous studies have advocated reduction aortoplasty to normalize the diameter of a moderately dilated ascending aorta associated with aortic valve disease. One of the reported techniques is the shawl lapel aortoplasty, which we have adopted and modified by setting a simple set of calculations. We present our midterm results.
