The construction project is a business full of risk in every process due to its complexity, changes, and involvement from various stakeholders. One of the critical risks in the construction project is in the supply chain. Identifying and assessing the risk with the right tools and methods in that area will inevitably affect the success of the project. Unfortunately, the research for the tools a...

the present study was conducted to determine peak ground acceleration (pga) over bedrock in probabilistic analysis methods for the seismic hazard and uniform hazard spectra at different hazard levels for esfahan city. a series of statistics containing historical and instrumental seismic data covering from the 8th century a.d. to the now up to a radius of 200 km was employed and seismic sources ...

Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...

Over the past few years, we have been developing safety cases for several NASA unmanned aircraft system (UAS) missions involving increasingly complex operational concepts. We have also begun including structured argumentation in the safety case reports to organize and explicitly document the reasons why the operations can be expected to be acceptably safe. Although each operation has particular...

Living in areas of highly active natural processes as the alpine environment demands the careful assessment of natural hazards and their provision in regional and local development planning processes, providing the chance to substantially reduce damage and loss of property and lives. Consequently techniques for the corresponding tasks of mapping and monitoring natural hazards are subject of ong...

A tsunameter (soo-NAHM-etter) network has been established in the Pacific by the National Oceanic and Atmospheric Administration. Named by analogy with seismometers, the NOAA tsunameters provide early detection and real-time measurements of deep-ocean tsunamis as they propagate toward coastal communities, enabling the rapid assessment of their destructive potential. Development and maintenance ...

nowadays, advances in information and communication technologies, has provided an opportunity for banks to provide their electronic services to their customers in remote areas. this technological innovation by e–banking systems has brought about many benefits to customers while it has been accompanied by a number of risks including the operational ones. this risks need to be identified and mana...

Wildfires have a profound impact upon the biosphere and our society in general. They cause loss of life, lead to the destruction of personal property and natural resources, and alter the chemistry of the atmosphere. In response to the concern over the consequences of wildland fire and to support the fire management community, the National Oceanic and Atmospheric Administration (NOAA), National ...
