The construction sector is responsible for a great environmental impact. cement industry, which included in this sector, emits about 650 to 800 kg of CO2 per each tonne produced, being one the most polluting industries terms greenhouse gas emissions. manufacturing process releases 7% total worldwide However, concrete and cement-based materials present uptake potential during their service life ...

Abstract Today, due to the rapid growth of population, development of the construction industry is a necessity. All around the world, new subjects such as sustainable development, environmental pollution, conservation of resources, and reduction of CO2 emission have become the most important research topics among the scientific societies. In recent years, especially after 1997, new tools were i...

A simple and efficient quantum non-demolition measurement (QND) scheme is proposed in which the arrival of a signal photon is detected without affecting the qubit state. The proposed QND scheme functions even if the ancillary photon is replaced with weak light composed of vacuum and one-photon states. Although the detection scheme is designed for entanglement sharing applications, it is also su...

Assuming an average latency of 42 years, the authors predict that incidence rates will peak in 2009 and that diagnoses will peak in 2014. However, they caution that ongoing use of chrysotile asbestos (which has been implicated but not conclusively established as a cause of mesothelioma) and the release of asbestos fibers from older buildings during demolition or reno­ vation may slow the projec...

A general discussion is given for first-kind (FK) and quantum non-demolition (QND) measurements. The general conditions for these measurements are derived, including the most general one (called the weak condition), an intermediate one, and the strongest one. The weak condition indicates that we can realize a FK or QND measuring apparatus of wide classes of observables by allowing the apparatus...

1.2 Statement of the Problem Our team was tasked to address the 18 departments located in the 4 wings of the Stone complex out of the 45 total departments located throughout the Stanford University Campus. These departments were slated for demolition and phased moves with a hierarchy of priorities and commitments. In addition there were functional relationship constraints, commitments associate...

In this paper we discuss the motivation, the technology, the design and the use-model of a novel web service for quantity surveyors, aiming to exploit virtual and augmented reality methods to implement a “zero waste” model, i.e. a new design paradigm where the waste materials from demolition become resources for reconstruction. The goal of this project is to provide virtual/augmented reality to...

We report the development of a fast pulse polarimeter for the application to quantum non-demolition measurement of atomic spin (Spin QND). The developed system was tunable to the atomic resonance of ytterbium atom and has narrow laser linewidth suitable for spin QND. Using the developed polarimeter, we successfully demonstrated the measurement of the vacuum noise, with 10 to 10 photon number pe...
