Illusion

An illusion is a distortion of the senses, revealing how the brain normally organizes and interprets sensory stimulation. Though illusions distort reality, they are generally shared by most people. Illusions may occur with any of the human senses, but visual illusions (optical illusions), are the most well-known and understood. The emphasis on visual illusions occurs because vision often dominates the other senses. For example, individuals watching a ventriloquist will perceive the voice is coming from the dummy since they are able to see the dummy mouth the words. Some illusions are based on general assumptions the brain makes during perception. These assumptions are made using organizational principles (e.g., Gestalt theory), an individual's capacity for depth perception and motion perception, and perceptual constancy. Other illusions occur because of biological sensory structures within the human body or conditions outside of the body within one’s physical environment.

The term illusion refers to a specific form of sensory distortion. Unlike a hallucination, which is a distortion in the absence of a stimulus, an illusion describes a misinterpretation of a true sensation. For example, hearing voices regardless of the environment would be a hallucination, whereas hearing voices in the sound of running water (or other auditory source) would be an illusion.

Faith Hill

Faith Hill (born Audrey Faith Perry; September 21, 1967) is an American country pop singer and occasional actress. She is one of the most successful country artists of all time, having sold more than 40 million albums worldwide. Hill is married to country singer Tim McGraw, with whom she has recorded several duets.

Hill's first two albums, Take Me as I Am (1993) and It Matters to Me (1995), were major successes and placed a combined three number ones on Billboard's country charts. She then achieved mainstream and crossover success with her next two albums, Faith (1998) and Breathe (1999). Faith spawned her first international hit, "This Kiss", and went multi-platinum in various countries. Breathe became her best-selling album to date and one of the best-selling country albums of all time, with the huge crossover success of the songs "Breathe" and "The Way You Love Me". It had massive sales worldwide and earned Hill three Grammy Awards, including Best Country Album.

In 2001, she recorded "There You'll Be" for the Pearl Harbor soundtrack and it became an international hit and her best-selling single in Europe. Hill's next two albums, Cry (2002) and Fireflies (2005), were both commercial successes and kept her mainstream popularity; the former spawned another crossover single, "Cry", which won Hill a Grammy Award, and the latter produced the hit singles "Mississippi Girl" and "Like We Never Loved at All", which earned her another Grammy Award.

Illusion (series)

The Illusion series, known in Japan as I Love Mickey Mouse, is a series of platforming video games licensed by Disney and developed/published by Sega exclusively for its consoles Master System, Mega Drive and Game Gear. The series follows the adventures of Disney's cartoon character Mickey Mouse (sometimes with Donald Duck) between various fantasy worlds. The series includes Castle of Illusion, and its sequels Land of Illusion, World of Illusion and Legend of Illusion. The first two games and the last game were released for Master System and Game Gear, and the first game and the third game were released for Mega Drive.

Transform (Rebecca St. James album)

Transform is the sixth studio album by Christian pop and rock singer Rebecca St. James. It was released on October 24, 2000 and debuted at No. 166 on the Billboard 200. The album spawned two of St. James' biggest hits, "Wait for Me" and "Reborn".

Background

Writing and development

Like her previous albums, Rebecca co-wrote the majority of the album, with the exception of "One" and "In Me". "For the Love of God" was written after Rebecca attended a missions trip to Romania, while the song "Reborn" was written about a friend coming to know Christ. Rebecca stated that "To see the joy and excitement in her new 'reborn' life is beautiful." Rebecca commented on the meaning of "Don't Worry" by saying "I am really quite a dramatic person and this song is a drama, a story, that challenges me to truly give things to God and not 'take them back' by worrying." "Merciful" was inspired by a book titled The Mitford Years, while "Universe" was penned after she took a walk by a creek next to her house, in which she was inspired of God's love.

Alpha–beta transformation

In electrical engineering, the alpha-beta () transformation (also known as the Clarke transformation) is a mathematical transformation employed to simplify the analysis of three-phase circuits. Conceptually it is similar to the dqo transformation. One very useful application of the transformation is the generation of the reference signal used for space vector modulation control of three-phase inverters.

Definition

The transform applied to three-phase currents, as used by Edith Clarke, is

where is a generic three-phase current sequence and is the corresponding current sequence given by the transformation . The inverse transform is:

The above Clarke's transformation preserves the amplitude of the electrical variables which it is applied to. Indeed, consider a three-phase symmetric, direct, current sequence

where is the RMS of , , and is the generic time-varying angle that can also be set to without loss of generality. Then, by applying to the current sequence, it results
