A quantum protocol for bit commitment the security of which is based on technological limitations on non demolition measurements and long-term quantum memory is presented.

Considering the necessity of A simulation tool developed to estimate and qualify waste from building demolition. The was using BIM enabled 4D-CAD combined with physics game engines it simulates impact output alternative demolition processes. In addition, Waste Distribution Maps (WDM) are generated support decision-making. This research represents a significant advancement in applied computing f...

The almost continuous reconstruction of healthcare facilities challenges the safety of patients because of the continual occupancy of hospitals. Traditional safety measures during construction have focused on avoiding hazards such as fire, mineral dust, and chemical aerosols. Since the development of transplant technology and other immunosuppressive therapies, opportunistic pathogens have becom...

The construction industry is one of the biggest and most active sectors of the European Union (EU), consuming more raw materials and energy than any other economic activity. Furthermore, construction waste is the commonest waste produced in the EU. Current EU legislation sets out to implement construction and demolition waste (CDW) prevention and recycling measures. However it lacks tools to ac...

It has recently been estimated that 72 million tonnes of Construction and Demolition (C&D) waste arose in 1999 in England and Wales accounting for approximately 20% of total waste arisings. Of this 35% is estimated to be recycled. Improving the efficiency of the construction and demolition industry is a key objective for the UK Government, with the publication of a strategy for more sustainable...

This paper focuses on one aspect of occupational dioxin exposure that is novel and unexpected. Exposures in excess of the German threshold limit value of 50 pg international toxicity equivalent (I-TEQ)/m3 are very frequent, unpredictable, and sometimes very high--up to 6612 pg I-TEQ/m3--during thermal oxygen cutting at scrap metal and demolition sites. The same procedure involving virgin steel ...

Land use change, in the form of urbanization, is one of the most significant forms of global change, and most cities are experiencing a rapid increase in population and infrastructure growth. However, a subset of cities is experiencing a decline in population, which often manifests in the abandonment of residential structures. These vacant and abandoned structures pose a land use challenge to u...

The construction industry is a capital-intensive sector that is steadily turning towards mechanized and automated solutions in the last few decades. However, due to some specificities of this field, it is still technologically behind other sectors, such as manufacturing. Robotic technologies provide room for improvements, that could lead to economical, technical, and also social benefits. We pr...

This paper provides new evidence on the effects of moving out of disadvantaged neighborhoods on the long-run economic outcomes of children. My empirical strategy is based on public housing demolitions in Chicago which forced households to relocate to private market housing using vouchers. Specifically, I compare adult outcomes of children displaced by demolition to their peers who lived in near...
