Waste materials are common problem in modern living. Waste accumulates from number of sources including domestic, industrial, commercial, construction and demolition activity. A significant portion of municipality waste is construction related. Proper management of construction and demolition waste is important or else it will get mixed with municipal waste. This type of mixing leads to cutting...

In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two d...

quantum information, deterministic linear optical gates, conditional measurements, hybrid systems We show how to construct a near deterministic CNOT using several single photons sources, linear optics, photon number resolving quantum non-demolition detectors and feed-forward. This gate does not require the use of massively entangled states common to other implementations and is very efficient o...

A brief account of the quantum information dynamics and dynamical programming methods for optimal control of quantum unstable systems is given to both open loop and feedback control schemes corresponding respectively to deterministic and stochastic semi-Markov dynamics of stable or unstable systems. For the quantum feedback control scheme, we exploit the separation theorem of filtering and cont...

The contemporary landscape is rife with ruins, from circumscribed tourist attractions to urban decay and demolition sites. When examined, our aesthetic experience of these sites ranges from historical distancing to the sublime and, when found in our local communities (e.g., Providence, RI), to discomfort, displacement, and horror. In particular, this paper is interested in how certain forms of ...

Electromagnetically induced transparency (EIT) has been often proposed for generating nonlinear optical effects at the single photon level; in particular, as a means to effect a quantum non-demolition measurement of a single photon field. Previous treatments have usually considered homogeneously broadened samples, but realisations in any medium will have to contend with inhomogeneous broadening...

We propose to measure the quantum state of a single mode of the radiation field in a cavity— the signal field—by coupling it via a quantum-non-demolition Hamiltonian to a meter field in a highly squeezed state. We show that quantum state tomography on the meter field using balanced homodyne detection provides full information about the signal state. We discuss the influence of measurement of th...
