Positive is a property of positivity and may refer to:
Positive is a 1990 documentary film directed, written and produced by Rosa von Praunheim. The film follows Silence = Death as the second part of von praunheim and Phil Zwickler’s trilogy about AIDS and activism.
This film documents New York City’s gay community’s response to the AIDS crisis during the 1980s as they were forced to organize themselves after the government’s slow response to stem the epidemic. Activist who are interviewed include New York filmmaker and journalist Phil Zwickler, playwright and gay activist Larry Kramer and musician Michael Callen who co-founded people with AIDS Coalition. Framing the individual stories of these three men is a chronicle of the creation of the Gay Men's Health Crisis, ACT- UP and Queer Nation as the gay community confronted the AIDS epidemic.
Comparison is a feature in the morphology or syntax of some languages, whereby adjectives and adverbs are inflected or modified to indicate the relative degree of the property defined by the adjective or adverb.
The grammatical category associated with comparison of adjectives and adverbs is degree of comparison. The usual degrees of comparison are the positive, which simply denotes a property (as with the English words big and fully); the comparative, which indicates greater degree (as bigger and more fully); and the superlative, which indicates greatest degree (as biggest and most fully). Some languages have forms indicating a very large degree of a particular quality (called elative in Semitic linguistics). Other languages (e.g. English) can express lesser degree, e.g. beautiful, less beautiful, least beautiful.
Comparatives and superlatives may be formed morphologically, by inflection, as with the English and German -er and -(e)st forms, or syntactically, as with the English more... and most... and the French plus... and le plus... forms. Common adjectives and adverbs often produce irregular forms, such as better and best (from good) and less and least (from little/few) in English, and meilleur (from bon) and mieux (from the adverb bien) in French.
Energy is a peer-reviewed academic journal covering research on energy engineering that was established in 1976. It is published by Elsevier and the editor-in-chief is Henrik Lund (Aalborg University). According to the Journal Citation Reports, the journal has a 2013 impact factor of 4.159, ranking it 13th out of 83 journals in the category "Energy & Fuels" and second out of 55 journals in "Thermodynamics".
In signal processing, the energy of a continuous-time signal x(t) is defined as
the energy of a discrete-time signal x(t) is defined as
Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:
For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing
by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.
"Energy" is the debut single by American recording artist Keri Hilson. The song was written and produced by The Runaways, consisting of Louis Biancaniello, Sam Watters, Rico Love, and Wayne Wilkins, for her studio album In a Perfect World… (2009).
The track was released as the first single from the singer's debut in the United States on May 27, 2008. Although being released worldwide it initially only charted in New Zealand at number two and only managed to reach top thirty on the U.S. Billboard Hot R&B/Hip-Hop Songs and Hot Dance Club Play charts.
Generally well received by music critics, it was named sixty-first on The Top 144 Songs of 2008 listing by Blender magazine.
"Energy" was written and produced by The Runaways. It was also recorded by The Runaways at Homesite 13 studios in Novato, California. and Hilson stated that she wanted to prove that she can be successful even without collaborations and guest vocalists and so it was announced "Energy" would be released as the next worldwide single following the success of "Knock You Down". The song was released on September 14, 2009 in the UK. On September 25, 2009 she appeared live on breakfast TV show GMTV in the UK where she performed the single. That same day, she appeared on BBC Radio 1's Live Lounge where she performed a stripped version of "Energy" as well as a gospel cover version of "Supernova" originally sung by Mr Hudson and Kanye West.
