The album was produced in Weed, California Weed , California by Sylvia Massy , who has worked with artists such as Tool band Tool and Spiderbait . Music videos for the songs My Enemy and Run have being made, and Run was also released as a CD single in August. The New Normal is in many ways a concept album , with the central concept being the oppression and injustice of a consumerist society. The ways in which we can solve these problems are also explored, as are their effects on an individual s state of mind. Another large concept on the album is the need to speak out against these issues hence the image of a megaphone in the front cover of the CD case . The New Normal was made the album of the week on Triple J , and was also nominated for the 2005 J Award . The album peaked at number 19 on the Australian Recording Industry Association s album chart.

In category theory and its applications to mathematics , a normal monomorphism or conormal epimorphism is a particularly well behaved type of morphism . A normal category is a category in which every monomorphism is normal. A conormal category is one in which every epimorphism is conormal. Definition A monomorphism is normal if it is the kernel category theory kernel of some morphism, and an epimorphism is conormal if it is the cokernel category theory cokernel of some morphism. A category C is binormal if it s both normal and conormal. But note that some authors will use only the word normal to indicate that C is actually binormal. Citation needed date January 2010 Examples In the category of groups , a monomorphism f from H to G is normal if and only if its image is a normal subgroup of G . In particular, if H is a subgroup of G , then the inclusion map i from H to G is a monomorphism, and will be normal if and only if H is a normal subgroup of G . In fact, this is the origin of the term normal for monomorphisms. Citation needed date January 2010 On the other hand, every epimorphism in the category of groups is normal since it is the cokernel of its own kernel , so this category is conormal. In an abelian category , every monomorphism is the kernel of its cokernel, and every epimorphism is the cokernel of its kernel. Thus, abelian categories are always binormal. The category of abelian group s is the fundamental example of an abelian category, and accordingly every subgroup of an abelian group is a normal subgroup.

To increase the value of an account with normal balance of debit, one would likewise debit the account. The fundamental accounting equation is the following Asset liability financial accounting Liability Owner s equity The account on left side of this equation has a normal balance of debit.

In algebraic geometry normal crossings is the property of intersecting geometric objects to do it in a transversal way. Normal crossing divisors In algebraic geometry , normal crossing divisors are a class of Divisor algebraic geometry divisors which generalize the smooth divisors. Intuitively they cross only in a transversal way. Let A be an algebraic variety , and math Z cup i Z i math a Divisor algebraic geometry reduced Cartier divisor , with math Z i math its irreducible components. Then Z is called a smooth normal crossing divisor if either i A is a algebraic curve curve , or ii all math Z i math are smooth, and for each component math Z k math , math Z Z k Z k math is a smooth normal crossing divisor. Equivalently, one says that a reduced divisor has normal crossings if each point tale topology tale locally looks like the intersection of coordinate hyperplanes. Normal crossings singularity In algebraic geometry a normal crossings singularity is a point in an algebraic variety that is locally isomorphic to a normal crossings divisor. Simple normal crossings singularity In algebraic geometry a simple normal crossings singularity is a point in an algebraic variety , the latter having smooth irreducible component irreducible components , that is locally isomorphic to a normal crossings divisor. Examples The normal crossing points in the algebraic variety called the Whitney umbrella are not simple normal crossings singularities. The origin in the algebraic variety defined by math xy 0 math is a simple normal crossings singularity. The variety itself, seen as a subvariety of the two dimensional Cartesian coordinate system affine plane is an example of a normal crossings divisor.

In mathematics , a normal surface is a surface inside a triangulated 3 manifold that intersects each tetrahedron so that each component of intersection is a triangle or a quad see figure . A triangle cuts off a vertex of the tetrahedron while a quad separates pairs of vertices. A normal surface may have many components of intersection, called normal disks , with one tetrahedron, but no two normal disks can be quads that separate different pairs of vertices since that would lead to the surface self intersecting. Image Normal surface.png 300px center thumb A normal surface intersects a tetrahedron in possibly many triangles see above left and quads see above right Dually, a normal surface can be considered to be a surface that intersects each handle of a given handle structure on the 3 manifold in a prescribed manner similar to the above. The concept of normal surface can be generalized to arbitrary polyhedra. There is also a related notion of almost normal surface . The concept of normal surface is due to Hellmuth Kneser , who utilized it in his proof of the prime decomposition 3 manifold prime decomposition theorem for 3 manifolds. Later Wolfgang Haken extended and refined the notion to create normal surface theory , which is at the basis of many of the algorithms in 3 manifold theory. The notion of almost normal surfaces is due to Hyam Rubinstein. Regina program Regina is software which enumerates normal and almost normal surfaces in triangulated 3 manifolds, implementing Rubinstein s 3 sphere recognition algorithm, among other things.

Orphan date February 2009 This article is about the philosophical argument for normal conditions in the sense of standards see the corresponding articles, e.g. Standard conditions for temperature and pressure . Normal conditions are a restriction on Philosophy philosophical arguments, especially in epistemology , in order to avoid objections perceived as digressive. As a reply to objections to an explanation of a phenomenon , e.g. a hypothesis or a theory , it is said, argument X holds only under normal conditions. In some cases, the concept of normal conditions tends to be rather blurred and the reply under normal conditions can tend to extend to everything that contradicts an argument. In cases, when the argument of normal conditions comes too often, according to the principle of Occam s Razor another explanation X has to be found.

The term normal score is used with two different meanings in statistics . One of them relates to creating a single value which can be treated as if it had arisen from a standard zero mean, unit variance normal distribution . The second relates to assigning alternative values to data points within a dataset, with the broad intention of creating data values than can be interpreted as being approximations for values that might have been observed had the data arisen from a standard normal distribution. The first meaning is as an alternative name for the standard score or z score , where values are standardised by subtracting the sample or estimated mean and dividing by the sample or other estimate of the standard deviation. Particularly in applications where the name normal score is used, there is usually a presumption that the value can be referred to a table of standard normal probabilities as a means of providing an informal significance test of some hypothesis, such as a difference in means. The second meaning of normal score is associated with data values derived from the ranking rank s of the observations within the dataset. A given data point is assigned a value which is either exactly, or an approximation, to the expectation of the order statistic of the same rank in a sample of standard normal random variable s of the same size as the observed data set. ref Everitt, B.S. 2002 The Cambridge Dictionary of Statistics 2nd Edition . Cambridge University Press. ISBN 052181099x ref Thus the meaning of a normal score of this type is essentially the same as a rankit , although the term rankit is becoming obsolete. In this case the transformation creates a set of values which is matched in a certain way to what would be expected had the original set of data values arisen from a normal distribution.
