Performances of a Newly High Sensitive Trilayer F/Cu/F GMI Sensor

We have selected stress-annealed nanocrystalline Fe-based ribbons for ferromagnetic/copper/ferromagnetic sensors exhibiting high magneto-impedance ratio. Longitudinal magneto-impedance reaches 400% at 60 kHz and longitudinal magneto-resistance increases up to 1300% around 200 kHz.Comment: 4 pages, 6 figures, Sensors and Actuators A (in review

Study of the Radiation Hardness Performance of PiN diodes for the ATLAS Pixel Detector at the SLHC upgrade

We study the radiation tolerance of the silicon and GaAs PiN diodes that will be the part of the readout system of the upgraded ATLAS pixel detector. The components were irradiated by 200 MeV protons up to total accumulated dose 1.2×1015 p/cm2 and by 24 GeV protons up to 2.6×1015 p/cm2. Based on obtained results, we conclude that radiation hardness does not depend on the sensitive area or cut off frequency of PiN diodes. We identify two diodes that can be used for the SLHC upgrade

Haptic-Based Shared-Control Methods for a Dual-Arm System

We propose novel haptic guidance methods for a dual-arm telerobotic manipulation system, which are able to deal with several different constraints, such as collisions, joint limits, and singularities. We combine the haptic guidance with shared-control algorithms for autonomous orientation control and collision avoidance meant to further simplify the execution of grasping tasks. The stability of the overall system in various control modalities is presented and analyzed via passivity arguments. In addition, a human subject study is carried out to assess the effectiveness and applicability of the proposed control approaches both in simulated and real scenarios. Results show that the proposed haptic-enabled shared-control methods significantly improve the performance of grasping tasks with respect to the use of classic teleoperation with neither haptic guidance nor shared control
