Sentences with phrase «detects changes in the frequency»

The researchers then visualized the velocity of the two liquids using a technique called Laser Doppler Velocimetry, which detects changes in the frequency of light waves when a laser beam hits them.

The patented QuickSensor (fig. 1) detects the changes in frequencies in a pet's nail due to sensing of the blood vessels and nerve endings in the quick.

They optically excited the NV - centers with light and scanned microwave frequencies in a process called optically detected magnetic resonance to determine any changes.

Various bat species that emit high - frequency squeaks to detect prey and avoid obstacles share a high degree of variation in the FOXP2 gene, according to a new study, suggesting that genetic changes in the gene helped promote the evolution of this ability.

«The bats also need to use the slow timing of the right hemisphere to use sonar — which relies on detecting small changes in frequency — to track the velocity of the fast - moving insects they fly after and eat,» Washington says.

However, in a subsequent analysis based on version 3 of the Hadley Model (HadCM3), Collins found that he could not detect a change in magnitude or frequency of ENSO as greenhouse gases increased, thus contradicting the results of his earlier study.

Similarly, he showed that the auditory cortex can change its map of sound frequencies after individuals are trained to detect fine differences in pitch.

They can sense the change in air pressure, and may hear low - frequency rumblings that we, humans, can't detect.

Since a conservative negative exponential or linear regression is employed in the detrending process, most low - frequency signals are preserved in the chronology and can be used to detect the low - frequency components of climate change.»

Detecting glacialquakes is important because glaciers appear to accelerate after large calving events.2 The frequency of glacialquakes — which has been rising since the late 1990s — has increased particularly since 2002.3 In fact, the number of quakes in 2005 was twice that of 2001.1 In late summer of 2005, glacial seismic activity was almost five times greater than in the winter months — most likely owing to seasonal changes in temperature.1,In fact, the number of quakes in 2005 was twice that of 2001.1 In late summer of 2005, glacial seismic activity was almost five times greater than in the winter months — most likely owing to seasonal changes in temperature.1,in 2005 was twice that of 2001.1 In late summer of 2005, glacial seismic activity was almost five times greater than in the winter months — most likely owing to seasonal changes in temperature.1,In late summer of 2005, glacial seismic activity was almost five times greater than in the winter months — most likely owing to seasonal changes in temperature.1,in the winter months — most likely owing to seasonal changes in temperature.1,in temperature.1, 3

A trend analysis of normalized insured damage from natural disasters is not only of interest to the insurance industry, but can potentially be useful for attempts at detecting whether there has been an increase in the frequency and / or intensity of natural hazards, whether caused by natural climate variability or anthropogenic climate change.

«Working with data pertaining to 7450 cardiovascular - related deaths that occurred within Budapest, Hungary, between 1995 and 2004 — where the deceased were «medico - legally autopsied» — Toro et al. looked for potential relationships between daily maximum, minimum and mean temperature, air humidity, air pressure, wind speed, global radiation and daily numbers of the heart - related deaths... scientists report and restate their primary finding numerous times throughout their paper, writing that (1) «both the maximum and the minimum daily temperatures tend to be lower when more death cases occur in a day,» (2) «on the days with four or more death cases, the daily maximum and minimum temperatures tend to be lower than on days without any cardiovascular death events,» (3) «the largest frequency of cardiovascular death cases was detected in cold and cooling weather conditions,» (4) «we found a significant negative relationship between temperature and cardiovascular mortality,» (5) «the analysis of 6 - hour change of air pressure suggests that more acute or chronic vascular death cases occur during increasing air pressure conditions (implying cold weather fronts),» (6) «we found a high frequency of cardiovascular death in cold weather,» (7) «a significant negative relationship was detected between daily maximum [and] minimum temperature [s] and the number of sudden cardiovascular death cases,» and (8) «a significant negative correlation was detected between daily mean temperature and cardiovascular mortality.»
