In this paper, the safety margin of seismically isolated buildings (SIBs) is probabilistically evaluated using Incremental Dynamic Analysis (IDA), and effect laminated rubber bearing’s hardening characteristics on SIBs also verified quantitatively. As a result, since non-consideration overestimates margin, it important to consider in evaluation superstructure’s margin. Also, tendency by IDA und...

The safety assessment of Nuclear Power Plants makes use of Thermal-Hydraulic codes for the quantification of the safety margins with respect to upper/lower safety thresholds, when postulated accidental scenarios occur. To explicitly treat uncertainties in the safety margins estimates within the Risk-Informed Safety Margin Characterization (RISMC) framework, we resort to the concept of Dynamic P...

Antibacterial drugs used in animal might result in deposition of residues in meat, milk and eggs. The presence of antimicrobial residues in animal-originated food is critical problem in many countries over the years. Because, drug residues might result in various health hazards, both actual incidence of reactions and potential hazards perceived by the public, the most countries assess residue o...

We present a new decision rule, maximin safety, that seeks to maintain a large margin from the worst outcome, in much the same way minimax regret seeks to minimize distance from the best. We argue that maximin safety is valuable both descriptively and normatively. Descriptively, maximin safety explains the well-known decoy effect, in which the introduction of a dominated option changes preferen...

We propose that the critical function of sleep [3] is to prevent uncontrolled neuronal feedback while allowing rapid responses and prolonged retention of short-term memories. The goal of learning is optimal behavior, and this sometimes requires the integration of sensory stimuli that are widely separated in time. At a neuronal level, this corresponds to persistent activity in local networks. Un...

Pedestrian-motor vehicle collisions account for over 6% of all workplace fatalities and are the leading cause of work related traumatic injury among highway workers. Interventions to reduce these accidents have focused primarily on vision. However, given the high demands on the visual attention of both pedestrian workers and vehicle operators, auditory warning might be a fruitful avenue for the...

nuclear cross sections that determine core multiplication strongly depend on core temperature (e.g., the doppler, moderator density effects etc). on the other hand, since this heat is generated by the neutron flux in the reactor core, the temperature distribution in the core will depend heavily on its neutronic behavior. fuel centerline temperature could be the limiting constraint on reactor po...
