Every year, many accidents leading to physical injuries in kindergartens, indicates that a very large percentage of them are related to the safety concerns and lack of hygiene in these places. Families, due to their busy life style and working hours and also children needs of preschool education, are searching to find most suitable kindergartens for their children. Selecting a kindergarten with...

A research program on failure modes induced by spherical indenters in brittle layer structures bonded to polymeric substrates, in simulation of occlusal function in all-ceramic dental crowns, is surveyed. Tests are made on model flat and curved layers bonded onto a dentin-like polymer base, in bilayer (ceramic/polymer) and trilayer (ceramic/ceramic/polymer) configurations. All-transparent syste...

Evaluating and enhancing resilience in water infrastructure is a crucial step towards more sustainable urban water management. As a prerequisite to enhancing resilience, a detailed understanding is required of the inherent resilience of the underlying system. Differing from traditional risk analysis, here we propose a global resilience analysis (GRA) approach that shifts the objective from anal...

the paper will provide a summary of all lifelines performance in this strong earthquake. the paper will discuss the damage, emergency response, and recovery of electric power, telecommunication, transportation (roads and bridges), seaports, airports, water and wastewater, and their facilities. the impact as a result of the lifelines service interruption will be discussed; most important is the ...

At the Computer Assurance COMPASS con ference Voas and Miller presented a technique for as sessing the failure tolerance of a program when the pro gram was executing in unlikely modes with respect to the expected operational pro le In that paper several preliminary algorithms were presented for inverting op erational pro les to more easily distinguish the unlikely modes of operation from the li...
