A model of the spatial and temporal distribution of seismicity both before and after the Northridge, California earthquake has been used to estimate the background stress state, loading rate, and some parameters relating to fault friction. A detailed source model was used to calculate the stress change eld from the Northridge mainshock, which 1 was t to the spatial distribution of seismicity. A...

background and objectives: studies have shown that patients awaiting coronary angiography (ca) are often anxious. high level of anxiety can lead to physical and psychological stress with adverse effects on organs, es­pecially heart. there is limited information on state and trait anxiety level in these patients in the literature. this study was thus designed to investigate the level of these tw...

In the present paper the applicability of state and rate dependent friction laws in describing the phenomena of high speed slip at metal-on-metal interfaces is investigated. For the purpose of model validation, results of plate-impact pressure-shear friction experiments were conducted by Irfan in 1998 and Irfan and Prakash in 2000 using a Ti6Al4V and Carpenter Hampden tool-steel tribo pair are ...

Aims. This study examines mood and cardiovascular variables related to job stress and burnout in hospital personnel. Main Methods. 400 nurses and physicians from a children's hospital in China were recruited. Participants completed job stress, burnout, and mood state questionnaires. Cardiovascular variables such as body mass index (BMI), triglyceride (TG), and high density lipoprotein (HDL) wer...

When electric current flows in a solder bump, electromigration generates stress, but creep relaxes it. After some time, the bump develops a steady-state stress field. We present a theory to show that the two processes — electromigration and creep — set an intrinsic length. When the intrinsic length is large compared to the height of the bump, electromigration is fast relative to creep and the s...

In this paper, we present a new entertainment adaptive framework AIRSF for stress free air travels. Based on the passenger’s current and target comfort states, user entertainment preference, and context of use, the system uses a Markov decision process to recommend context-aware and personalized stress reduction entertainment to transfer the passenger from the current state to the target comfor...
