Exempel på hur man kan använda INCIDENCE i en mening

• A large generalization of this formula applies to summation over an arbitrary locally finite partially ordered set, with Möbius' classical formula applying to the set of the natural numbers ordered by divisibility: see incidence algebra.
• As the angle of incidence approaches a certain threshold, called the critical angle, the angle of refraction approaches 90°, at which the refracted ray becomes parallel to the boundary surface.
• Zeta function of an incidence algebra, a function that maps every interval of a poset to the constant value 1.
• Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.
• At near vertical incidence, the limiting frequency at or below which incidence, the wave component is reflected by, and above which it penetrates through, an ionospheric layer.
• Reflectance is a component of the response of the electronic structure of the material to the electromagnetic field of light, and is in general a function of the frequency, or wavelength, of the light, its polarization, and the angle of incidence.
• In optics, the law is used in ray tracing to compute the angles of incidence or refraction, and in experimental optics to find the refractive index of a material.
• A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.
• The incidence of a tax does not depend on whether the buyers or sellers are taxed since taxes levied on sellers are likely to be met by raising the price charged to buyers.
• On 3 May 2001, he appeared on the Dutch television program Nova to discuss the rising incidence of anti-homosexual violence by Moroccan youths.
• This works at a wide range of angle of incidence, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
• Semmelweis discovered that the incidence of infection could be drastically reduced by requiring healthcare workers in obstetrical clinics to disinfect their hands.
• Some inland areas, where soil and water lacks iodine compounds and consumption of marine foods is low, are known for higher incidence of goitre.
• It occurs when a sufficient percentage of a population has become immune to an infection, whether through previous infections or vaccination, that the communicable pathogen cannot maintain itself in the population, its low incidence thereby reducing the likelihood of infection for individuals who lack immunity.
• A study commissioned by NASA lends credence to the perception that Satellite Beach is located in a portion of the North American Atlantic shoreline with a reduced incidence of catastrophic hurricanes.
• In September 2018, the Illinois Department of Public Health began a cancer incidence study based on the recommendation of the Agency for Toxic Substances and Disease Registry.
• Between 1997 and 2003, the Fallon community experienced an unusually high incidence of childhood leukemia.
• Expenditure incidence, the effect of government expenditure upon the distribution of private incomes.
• However, mathematically, prevalence is proportional to the product of the incidence and the average duration of the disease.
• Subalgebras called reduced incidence algebras give a natural construction of various types of generating functions used in combinatorics and number theory.
