Abstract This paper presents the application of a Structural Health Monitoring (SHM) strategy for bridges affected by slow deformation phenomena to curved roadway bridge undergoing landslide‐induced movements. The chosen multidisciplinary approach is based on combination remote sensing data through satellite Synthetic Aperture Radar Interferometry (InSAR) and structural analysis up collapse inv...

progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. the current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. this method is suitable especially in the case of blast-induced progressive ...

Earth's surface temperatures are projected to increase by ~1-4°C over the next century, threatening the future of global biodiversity and ecosystem stability. While this has fueled major progress in the field of physiological trait responses to warming, it is currently unclear whether routine population monitoring data can be used to predict temperature-induced population collapse. Here, we int...

The solvent composition induced reentrant behavior of poly(N-isopropylacrylamide) (PNIPAM) chains grafted on a SiO2 surface in water-methanol mixtures was investigated using a quartz crystal microbalance with dissipation monitoring (QCM-D) at 20 degrees C. The frequency and energy dissipation responses showed that the grafted PNIPAM chains sharply collapse when the methanol content (x(m)) reach...

Neurotransmission depends on movements of transmitter-laden synaptic vesicles, but accurate, nanometer-scale monitoring of vesicle dynamics in presynaptic terminals has remained elusive. Here, we report three-dimensional, real-time tracking of quantum dot-loaded single synaptic vesicles with an accuracy of 20 to 30 nanometers, less than a vesicle diameter. Determination of the time, position, a...

A middle age man underwent immediate cardiopulmonary resuscitation (CPR) for ventricular fibrillation (VF) occurred in an ambulance. After arrival in a regional hospital, return of spontaneous circulation (ROSC) was achieved 82 minutes after the collapse. He was in coma even three hours after ROSC. So, he was transferred to our university hospital to receive therapeutic hypothermia (TH). An ini...

The changing nature of the distribution grid leads to new concerns in system operation. New resources connected at the distribution level, changing load characteristics, and increased reliability requirements all point to the need for improved monitoring and control capabilities. Many existing synchrophasor applications have been installed to address distribution concerns. These applications in...

The paper presents a reconfigurable wireless sensor network for structural health monitoring. Real-time and periodic structural health monitoring can reduce the probability of collapse and the consequences of potential life-threatening conditions. The monitoring system is composed of two parts: the wireless network in which the sensor nodes are equipped with a 3axis accelerometer and a temperat...
