Circular Transitional Housing for displaced people in extreme conditions: the case of Pakistan

Global displacement has been rapidly increasing over the last decades and is expected to rise even further in the upcoming years due to the negative impacts of climate change and more frequent and severe weather events. This highlights the growing demand for sustainable housing for the displaced. Transitional housing is a structurally sound...

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...

Refugee Shelters done Differently: Humanist Architecture of Socialist Yugoslavia

UNDOCUMENTED: From Liminal Politics to Intimate Spaces

The protagonist of this work is the rightless, displaced person - a population of individuals in transition, hidden like a shadow in the contemporary city. Departing from the active oppression of this considerable group from the fabric of the city and the ways in which architecture contributes to enclosing or dividing populations, this work...

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...

From congestion to decongestion: displacement of flows of goods in the last-mile transition from land to sea

Agitation takes control when distance collapses. Contrast of different states of existence and change of the environment are easier to detect than those constant ones. Drawn from climatic, geopolitical and socio-economic scenarios of the North Sea, intermodal transport of goods, particularly the last-mile which crosses land-sea boundaries, will...

Roadmap towards inclusiv(c)ity: An exploration of Neighbourhood planning to minimise processes of displacement in gentrified London

Due to its global economic attractive power, London is growing as never before. And although the divided and global city strives to develop towards more inclusivity in the city, the growth, revitalisation, redevelopment and renewal in London currently takes forms of exclusive urban development, better known as gentrification. This gentrification...

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...

A follow-up feasibility study to an amphibious spray pontoon

Beach nourishments or sand replenishments are applied by the use of pipelines or the rainbow method. Replenished sand is then moved and levelled by bulldozers. This is a passive approach to process the outflow of material. The land based equipment is dependent from tides and water levels, and significant effort is required to install and...

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...

Fluid Flow Visualization through Porous Media

We have built a set-up enabling direct visualization of fluid displacement and interaction in a transparent porous media at pore scale resolution. We have been able to image successive 2D planes in order to reconstruct the 3D configuration of residual oil after secondary imbibition for mobilization and displacement experiments. We visualized the...

Displacement methods based on field analysis

Finite element analyses of stable crack growh in thin sheet material

This study deals with fracture mechanics aspects of mode 1 crack growth under montonically increasing (quasi-static) loads. Using the finite element method stable crack growth and the plastic deformation fields associated with this process are analyzed. A two parameter approach is proposed for a description of initiation and subsequent stable...
