Recently, extensive research efforts have been dedicated to develop fifth-generation (5G) wireless mobile networks aimed at providing ubiquitous connections for anyone and anything irrespective of time location. The number connected devices data traffic is increasing exponentially every day, future data-intensive applications like AR/VR, holographic communications, V2X, autonomous driving, high...

MODEL REFERENCE CONTROL FOR ULTRA-HIGH PRECISION POSITIONING SYSTEMS by Lan Yu Due to the increasing demands of high-density semiconductors, molecular biology, optoelectronics, and MEMS/NEMS in the past decades, control of ultra-high precision positioning using piezoelectricity has become an important area because of its high displacement resolution, wide bandwidth, low power consumption, and p...

This paper introduces a new methodology to design modular industrial ultra-high precision robots; it aims at significantly reducing both the complexity of their design and their development time. This modular concept can be considered as a robotic Lego®, where a finite number of building bricks is used to quickly design the robot and to easily change its mobility. The core of the concept is the...

The measurement of ultra-precision freeform surfaces commonly requires several datasets from different sensors to realize holistic measurements with high efficiency. The effectiveness of the technology heavily depends on the quality of the data registration and fusion in the measurement process. This paper presents methods and algorithms to address these issues. An intrinsic feature pattern is ...
