A high-resolution micro-torsion tester is developed based on electromagnetism, and the shear modulus of metallic glass fiber (Pd40Cu30Ni10P20) is measured using this tester. The torque is measured by a coil-magnet component and the rotation angle is measured by an inductive angular transducer. The calibration results show that the torque capacity of this tester is 1.1 × 10−3 N m with resoluti...

INTRODUCTION: Anatomical marker placement reliability is an important consideration in 3D gait analysis given its influence on defining joint centers, anatomical coordinate systems (ACSs), and ultimately the resulting joint kinematic outputs. It has been postulated that gait kinematic reliability could be improved using a functional (FUN) method compared to a manual marker placement approach (M...

A novel approach for using an embedded processor to aid in deterministic testing of the other components of a system-on-a-chip (SOC) is presented. The tester loads a program along with compressed test data into the processor’s on-chip memory. The processor executes the program which decompresses the test data and applies it to scan chains in the other components of the SOC to test them. The pro...

The Gyrover is a single wheel gyroscopically stabilized mobile robot developed at Carnegie Mellon University. An internal pendulum serves as a counter weight for a drive motor that causes fore/aft motion, while a tilt-mechanism on a large gyroscope provides a mechanism for lateral actuation. In this paper, we develop a detailed dynamic model for the Gyrover, and use this model in an extended Ka...

This paper presents driving and balancing control of a single-wheel mobile robot system called the name of GYROBO. GYROBO utilizes a gyro effect to stabilize itself. Three actuators are used to perform driving and balancing tasks. After modification of hardware and relocation of materials inside the wheel housing of the previous GYROBO model, performances of trajectory following control as well...

Electrical steel is the most commonly used soft magnetic material in electrical energy conversion and transmission, its demand expected to increase with need for electrification of transportation sector transition renewable combat climate change. Although iron silicon has been more than 100 years, some fundamental relationships between microstructure performance remain vague, especially regard ...
