Purgation and purification, used in previous centuries, as the common interpretations of catharsis are still in wide use today.

Carbide lamps systems are an older form of illumination, inspired by miner's equipment, and are still used by some cavers.

Also, some relatively minor additions to the reaction can be indicated above the reaction arrow ; examples of such additions are water, heat, illumination, a catalyst, etc.

The resulting values of illumination throughout the model ( sometimes including for empty spaces ) are stored and used as additional inputs when performing calculations in a ray-casting or ray-tracing model.

Thought processes and mental events are conscious only to the extent they receive illumination from Purusha.

Much as in a sunset, the atmosphere tends to more strongly scatter light with shorter wavelengths, so the illumination of the Moon by refracted light has a red hue, thus the phrase ' Blood Moon ' is often found in descriptions of such lunar events as far back as eclipses are recorded.

Global illumination is a general name for a group of algorithms used in 3D computer graphics that are meant to add more realistic lighting to 3D scenes.

Such algorithms take into account not only the light which comes directly from a light source ( direct illumination ), but also subsequent cases in which light rays from the same source are reflected by other surfaces in the scene, whether reflective or not ( indirect illumination ).

Theoretically reflections, refractions, and shadows are all examples of global illumination, because when simulating them, one object affects the rendering of another object ( as opposed to an object being affected only by a direct light ).

Radiosity, ray tracing, beam tracing, cone tracing, path tracing, Metropolis light transport, ambient occlusion, photon mapping, and image based lighting are examples of algorithms used in global illumination, some of which may be used together to yield results that are not fast, but accurate.

More and more specialized algorithms are used in 3D programs that can effectively simulate the global illumination.

Notable accounts of encounters with the Holy Spirit in this fashion are found in St Symeon the New Theologian's account of the illumination of ' George ' ( considered a pseudonym of St Symeon himself ); in the ' conversation with Motovilov ' in the Life of St Seraphim of Sarov ( 1759 – 1833 ); and, more recently, in the reminiscences of Elder Porphyrios ( Wounded by Love pp. 27 – 31 ).

Thus the Ittō-ryū ( Single sword school ) indicates the founder's illumination that all possible cuts with the sword emanate from and are contained in one original essential cut.

They relate to raw power by a quantity called luminous efficacy, and are used for purposes like determining how to best achieve sufficient illumination for various tasks in indoor and outdoor settings.

Rheinberg illumination is a special variant of dark field illumination in which transparent, colored filters are inserted just before the condenser so that light rays at high aperture are differently colored than those at low aperture ( i. e. the background to the specimen may be blue while the object appears self-luminous red ).

Most fluorescence microscopes are operated in the Epi-illumination mode ( illumination and detection from one side of the sample ) to further decrease the amount of excitation light entering the detector.

However, this information is blurred by the fact that, upon illumination, all fluorescently labeled structures emit light, irrespective of whether they are in focus or not.

Structured illumination can improve resolution by around two to four times and techniques like stimulated Emission Depletion microscopy are approaching the resolution of electron microscopes.

Phase contrast microscopy is an optical microscopy illumination technique in which small phase shifts in the light passing through a transparent specimen are converted into amplitude or contrast changes in the image.

The lamps represent the illumination of the 7 stars, and lighting them are believed to absolve sins while prolonging one's lifespan.

In 1888 the three largest hotels ( Genazzini, Grande Bretagne and Grand Hotel Bellagio ) first introduced electric light substituting the gas illumination, and only after this were they followed by many patrician homes.

Murry vividly narrates this exploration as a spiritual conversion — what he describes as a " desolation " followed by " illumination " -- after the death of Katherine Mansfield ( who had moved to Gurdjieff's Institute for the Harmonious Development of Man where she died ).

He often discussed Platonic philosophy, the illumination of the mind and soul by direct communion with Spirit ; upon the spiritual and poetic monitions of external nature ; and upon the benefit to man of a serene mood and a simple way of life.

There is also a fountain ( şadırvan ) where worshipers can perform ritual ablutions before prayer ; the dome over the şadırvan is capped by a skylight which creates a soft, serene light below ; thus playing an important role in the illumination of the large building.

* indirect illumination — surfaces illuminated by light reflected off other surfaces, rather than directly from a light source ( also known as global illumination )

A more sophisticated method is to modify the colour value by an illumination factor, but without calculating the relationship to a simulated light source.

This occurs, for example, during an eclipse of the Moon by the Earth — producing a faint, ruddy illumination of the Moon even at totality.

His scientific work was chiefly concerned with galvanism, anatomy and its medical applications, with the construction and illumination of lighthouses, and with experiments for preserving human life and material objects from destruction by fire.

In real-time 3D graphics, the diffuse inter-reflection component of global illumination is sometimes approximated by an " ambient " term in the lighting equation, which is also called " ambient lighting " or " ambient color " in 3D software packages.

* GI Tutorial-Video tutorial on faking global illumination within 3D Studio Max by Jason Donati

The illumination measured by a photocell sensor does not necessarily correspond to what is perceived by the human eye, and without filters which may be costly, photocells and charge-coupled devices ( CCD ) tend to respond to some infrared, ultraviolet or both.

Energy conservation advocates contend that light pollution must be addressed by changing the habits of society, so that lighting is used more efficiently, with less waste and less creation of unwanted or unneeded illumination.

A medieval Armenian illumination, by Toros Roslin.

Image: Paper_Micrograph_Dark. png | Dark field illumination, sample contrast comes from light scattered by the sample.

Dark field illumination uses a carefully aligned light source to minimize the quantity of directly-transmitted ( unscattered ) light entering the image plane, collecting only the light scattered by the sample.

The falloff is approximated by the cos < sup > 4 </ sup > or " cosine fourth " law of illumination falloff.

It is in prose, consisting of twelve verses expounding the mystic syllable Aum, the three psychological states of waking, dreaming and sleeping, and the transcendent fourth state of illumination.

* Hydrargyrum medium-arc iodide lighting, a type of illumination used in the film industry, for stage lighting and large image projection.

The Induction that precedes the text mentions a small sized stage and candles for illumination, details that verify that the play was acted in a smaller " private " theatre rather than a large " public " one like the Globe or the Fortune.

In Eastern Orthodox theology, theoria refers to a stage of illumination on the path to theosis, in which one beholds God.

The common swivel axis for microscope and illumination system was connected to the cross-slide stage, which allowed it to be brought to any part of the eye to be examined.

The building, with perfect technical equipment ( electric illumination, a steel-constructed stage ), served without any extensive modifications for almost one hundred years.

A fade refers to a change in illumination for the entire stage.

This act snaps the already fragile mind of Naoto, driving him to an escalation of violence that stops only with the death of Tiger The Great, smashed under the illumination stage.

Debevec's more recent research has included methods for recording real-world illumination for use in computer graphics ; a number of novel inventions for recording ambient and incident light have resulted from the work of Debevec and his team, including the light stage, of which five or more versions have been constructed, each an evolutionary improvement over the previous.

A typical stepper has the following subassemblies: wafer loader, wafer stage, wafer alignment system, reticle loader, reticle stage, reticle alignment system, reduction lens, and illumination system.

In television, film, stage, or photographic lighting, a fill light ( often simply fill ) may be used to reduce the contrast of a scene and provide some illumination for the areas of the image that are in shadow.
