The construction and demolition waste (CDW), which is produced by the construction process, presents 33% of the total waste stream in European Union in year 2010 (Eurostat 2010). A construction and demolition waste is generated during whole life cycle of construction design phase, realization phase, occupation phase and demolition phase. On the other hand, the sustainable design of construction...

Policies focusing on enforcing property code violations and the improvement of vacant properties are argued to be more efficacious than demolition policies to fight urban blight. This study applies parcel level data to a multi-year hybrid modeling structure. A fine-grained analysis is conducted on the dynamic patterns of abandonment and demolition for a unique period of four years before and af...

This paper has mainly discussed the influence on society and culture of engineering demolition, by analyzing constraint problems of engineering demolition starting with noise pollution, dust pollution, hidden danger and cultural value loss, of which the reasons have been expounded and some corresponding countermeasures have been proposed.

Homodyne detection is one of the ways to circumvent the standard quantum limit for a gravitational wave detector. In this paper it will be shown that the same quantum-non-demolition effect using homodyne detection can be realized by heterodyne detection with unbalanced RF sidebands. Furthermore, a broadband quantum-non-demolition readout scheme can also be realized by the unbalanced sideband de...

A prototype knowledge based safety advisor system has been built. Known as SADI (Safety Advisor for the Demolition Industry), the system gives advice to those involved in the management, planning, execution and control of demolition work. The knowledge underlying what is safe and what is unsafe is contained in legislative documents, and in the expertise of the engineers, planners and inspectors...

BACKGROUND Within the construction industry the risk of lung disorders depends on the specific professions probably due to variations in the levels of dust exposure, and with dust levels depending on the work task and job function. We do not know the extent of exposure in the different professions or the variation between the different work tasks. The purpose of this study was therefore to asse...

Housing is a fundamental human right and a social determinant of health. According to international law, indigenous peoples are entitled to special housing and health rights and protections. In Israel, land disputes between the government and Arab Bedouins, an indigenous minority, have resulted in ongoing demolitions of Arab Bedouin homes, with thousands more homes threatened. While demolitions...

Hurling a successful Construction and Demolition Waste (C&DW) recycling operation around the globe is a challenge today, predominantly because secondary materials markets are yet to be integrated. Reducing, Reusing and recycling of (C&DW) have been employed over the years, and various techniques have been investigated. However, the economic and environmental viability of its application seems l...

We discuss a new and novel approach to the problem of creating a photon number resolving detector using the giant Kerr nonlinearities available in electromagnetically induced transparency. Our scheme can implement a photon number quantum non-demolition measurement with high efficiency ( 99%) which can distinguish 0, 1 and 2 photons. We then show how it is possible to construct a near determinis...
