Gentrification and the Origin and Destination of Movers: A Systematic Review

Gentrification is a process whereby neighbourhoods and their socio-economic composition upgrade through residential moves and social mobility. Relatively little attention has been paid to the spatial aspect of gentrification-induced residential moves. This systematic literature review focuses on the origin and destination of moves to and from...

A 200-μW Interface for High-Resolution Eddy-Current Displacement Sensors

This article presents a low-power eddy-current sensor interface for touch applications. It is based on a bang-bang digital phase-locked loop (DPLL) that converts the displacement of a metal target into digital information. The PLL consists of a digitally controlled oscillator (DCO) built around a sensing coil and a capacitive DAC, a...

Understanding the Experiences of Relocatees during Forced Relocation in Chinese Urban Restructuring

Despite the massive forced relocation of residents during urban restructuring in China, there is no systematic overview regarding how residents experience the process and its outcomes. Most studies concerning urban restructuring in China directly equate forced relocation with displacement, which has a negative connotation. This predominantly...

A 19.8-mW Eddy-Current Displacement Sensor Interface with Sub-Nanometer Resolution

This paper presents an eddy-current sensor (ECS) interface intended for sub-nanometer (sub-nm) displacement sensing in hi-tech applications. The interface employs a 126-MHz excitation frequency to mitigate the skin effect, and achieve high resolution and stability. An efficient on-chip sensor offset compensation scheme is introduced which...

Suppression Efficiency of the Correlated Noise and Drift of Self-oscillating Pseudo-differential Eddy Current Displacement Sensor

The suppression efficiency of the correlated noise and drift of self-oscillating front-end circuit in a pseudo-differential eddy-current displacement sensor (ECDS) is investigated using COMSOL and MATLAB. The transfer characteristic of the sensor coil, excited at 200 MHz, is obtained through a FE model in COMSOL. The characteristic is linearized...

Controlling adhesion between multi-asperity contacting surfaces in MEMS devices by local heating

In this work, we have incorporated heaters in a MEMS device, which allow the in situ local heating of its contacting surfaces. This design offers a promising solution for MEMS devices with contacting components by preventing capillary-induced adhesion. The force of adhesion was assessed by optically measuring in-plane snap-off displacements. We...
