rainfall is recognized as one of the main triggering factors of landslides. researchers have long attempted to determine the amount of precipitation required to trigger slope failures. one of the landslide zones in iran is chaharmahal & bakhtiari province where many landslides cause high casualties in recent decades. it is significant that most of these landslides occur after a rainy period...
Stochastic resonance (SR) occurs when the detection of a subthreshold signal is aided by the presence of random energy fluctuations in the signal modality, commonly called noise. SR is counterintuitive because such noise usually worsens performance. Nonetheless, SR has been demonstrated both theoretically and experimentally in human sensory systems. Using a psychophysically sophisticated paradi...
The behavioral financial perspective shows some changes in the price of securities have no fundamental reason and depend on the irrational behaviors of investors as measured by the investor sentiment. Investor sentiment plays an important role in the volatility of securities prices and returns. At first, by finding the thresholds and testing these points statistically, we showed that the invest...
The mini-project work undertaken by us involves the design & development of an automatic railway gate control and alarm system using Arduino. It has been noticed that a lot fatalities lives occur everyday due to manually operated rail gates. These happen mainly at places where road passes through city, locality or unmanned gates crossing zones. Currently, gatemen operate on assumption train...
We assessed reproducibility of measurements of rectal compliance and sensation in health in studies conducted at two centres. We estimated samples size necessary to show clinically meaningful changes in future studies. We performed rectal barostat tests three times (day 1, day 1 after 4 h and 14-17 days later) in 34 healthy participants. We measured compliance and pressure thresholds for first ...
[Purpose] The purpose of the present study was to compare the sensory thresholds of healthy subjects using pre-programmed or single-frequency transcutaneous electrical nerve stimulation. [Subjects] Ninety healthy adult subjects were randomly assigned to pre-programmed or single-frequency stimulation groups, each consisting of 45 participants. [Methods] Sensory thresholds were measured in the pa...
This paper describes the design of a new instrumental technique, Gas Chromatography Recomposition-Olfactometry (GC-R), that adapts the reconstitution technique used in flavor chemistry studies by extracting volatiles from a sample by headspace solid-phase microextraction (SPME), separating the extract on a capillary GC column, and recombining individual compounds selectively as they elute off o...
Large variability in thresholds to sensory stimuli is observed frequently even in healthy populations. Much of this variability is attributed to genetics and day-to-day fluctuation in sensitivity. However, false positives are also contributing to the variability seen in these tests. In this study, random number generation was used to simulate responses in threshold methods using different "stop...
Rangeland ecosystems shift across dynamic thresholds between differentecological states in response to natural or human-induced factors. These differentecological states are the result of interactions among climate, soils, grazing history,and management practices. The notion of a single ‘‘pristine’’ final state is onlyconceptual in nature, and because of this, dynamic thresholds and the effects...
Background: Different studies have shown that Otoacoustic Emission (OAEs) is generated by Outer Hair Cells (OHCs) and these sensory cells are first structures exposed to damage of high level noise. Therefore minor impairment in OHCs can lead to lack of response of OAE. The purpose of the current study is to compare the pure tone thresholds, Transient Evoked Otoacoustic Emission (TEOAE...
