Enhancing and Impeding Policies Before and During the Crisis
2014In Chap. 4, we introduced the internal and external environment that impacted each country’s crisis response and recovery. In Chap. 5, we reported on stimulus packages and consolidation of various types. Through investigating the macro environment, micro environment and the crisis coping measures of these 48 countries, we found some policies could ...

An enhanced piezoelectric impedance approach for damage detection with circuitry integration
Smart Materials and Structures, 2009Piezoelectric impedance-based damage detection approach has been recognized to be sensitive to small-sized damage, as the impedance information can be measured at relatively high frequency range. To enhance this approach, recently an innovative scheme is developed by integrating the inductive circuitry serially with the piezoelectric transducer.

Chinese Culture and Value: Enhancing or Impeding Innovation?
2015Chapter 2 gives a clear picture of the facts of Chinese innovation, both in terms of invention as patent registration, and organizational innovation as product, process and strategy. Once “China-also innovates” is evidenced as showed in Chapter 1, one may wonder whether that is a generic phenomenon or a specific individual case.

Unifying bilateral teleoperation and tele-impedance for enhanced user experience
The International Journal of Robotics Research, 2019Usability is one of the most important aspects of teleoperation. Ideally, the operator’s experience should be one of complete command over the remote environment, but also be as close as possible to what they would have if physically present at the remote end, i.e., transparency in terms of both action and perception.

On the enhanced passivity of pneumatically actuated impedance-type haptic interfaces
IEEE Transactions on Robotics, 2006The stable simulation of high-stiffness surfaces remains a challenge in impedance-type haptic simulations of mechanical environments. In this paper, the authors propose an approach to achieving a stable, high-stiffness surface in a haptic interface by leveraging the open-loop properties of pneumatic actuators.

Enhanced-Boost Z-Source Inverters With Switched Z-Impedance
IEEE Transactions on Industrial Electronics, 2016This paper proposes a new topology for an enhanced-boost Z-source inverter (ZSI) with combined two Z-impedance networks. By two Z-impedance networks and low shoot-through duty cycle, the proposed inverter produces high output voltage gain. In traditional ZSIs for high boosting voltage, a low modulation index is required; hence, under these conditions ...

Resonance-enhanced microfluidic impedance cytometer for detection of single bacteria
Lab on a Chip, 2014This paper reports on a novel impedance-based cytometer, which can detect and characterize sub-micrometer particles and cells passing through a microfluidic channel. The cytometer incorporates a resonator, which is constructed by means of a discrete inductor in series with the measurement electrodes in the microfluidic channel.

Gaussian filtering for enhanced impedance parameters identification in robotic assembly processes
2015 IEEE 20th Conference on Emerging Technologies & Factory Automation (ETFA), 2015Robot interaction with the environment is normally described as a mass-spring-damping impedance model and the estimation of such interaction impedance parameters requires the computation of the joint (or task) space velocity and acceleration. In many cases, the velocity and acceleration are computed by numerically computing the first and second ...

Silent-interval impedance matching for short pulse CAN to enhance scalability
2015 21st Asia-Pacific Conference on Communications (APCC), 2015Controller area network (CAN) is a communication standard for in-vehicle networks and is widely employed by a number of vehicle lines. Recently, it is required for CAN to enhance the scalability of bus topology and bit rate because the functionality of in-vehicle devices is becoming high and their number is increasing.
