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...

Dedicated to Heinz Dehnen in honour of his 65 birthday. In this work we obtain a family of quantum nondemolition variables for the case of a particle moving in an inhomogeneous gravitational field. Afterwards, we calculate the corresponding propagator, and deduce the probabilities associated with the possible measurement outputs. The comparison, with the case in which the position is being moni...

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...

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...
