Fiber Optic Distributed Sensors for High-resolution Temperature Field Mapping

12.4K
We demonstrate use of a fiber optic distributed sensor for mapping the temperature field of mixing air jets. The Rayleigh scattering-based sensor generates thousands of data points along a single fiber to provide exceptional spatial resolution that is unattainable with traditional sensors such as...

Light travels at different speeds depending on the material through which it is propagating. When light travels from one material to another, it will either slow down or speed up. In order to conserve energy and momentum, the light must change the direction in which it propagates. This bending of light is known as refraction. Some fraction of...

Cultural Insensitivity and Stereotypes

979
Cultural insensitivity and stereotypes in marketing can lead to significant missteps, damaging a brand's reputation and alienating potential customers.
Cultural insensitivity refers to a lack of respect or understanding for cultural differences, often resulting in offensive or inappropriate marketing messages. For instance, using wrong cultural symbols or failing to understand local customs can be seen as disrespectful.
Stereotypes, on the other hand, are overgeneralizations about certain...
