  Negligible set - Wikipedia, the free encyclopedia
As common examples, finite sets can be ignored when studying the limit of a sequence, and null sets can be ignored when studying the integral of a measurable function.
Negligible sets define several useful concepts that can be applied in various situations, such as truth almost everywhere.
In order for these to work, it is generally only necessary that the negligible sets form an ideal; that is, that the empty set be negligible, the union of two negligible sets be negligible, and any subset of a negligible set be negligible.

 Station Information - Null set
In measure theory, a null set is a set whose measure is zero, so that it is negligible for the purposes of the measure in question.
Thus, null sets may be interpreted as negligible sets, defining a notion of almost everywhere.
Null sets play a key role in the definition of the Lebesgue integral: if functions f and g are equal except on a null set, then f is integrable if and only if g is, and their integrals are equal.

 Negligence Law   (Site not responding. Last check: 2007-10-07)
In the realm of criminal common law, criminal negligence is a legal term of art for a state of mind which is careless, inattentive, neglectful, willfully blind, or reckless; it is the ''mens rea'' part of a crime which, if occurring simultaneously with the ''actus reus'', gives rise to criminal liability.
Some distinguish recklessness from negligence; recklessness is a 'malfeasance' that increases the danger of an act occurring; whereas criminal negligence is a 'misfeasance or 'nonfeasance,'merely allowing otherwise avoidable dangers to manifest.
Gross criminal negligence is behaviour which involves a "wanton disregard for human life." Of course, in all these cases if the actus reus or bad act never occurs then there is no crime as both elements are necessary under the criminal common law to sustain a guilty conviction.

 Nowhere dense set - Encyclopedia, History, Geography and Biography
For example, the set of rational numbers, as a subset of R has the property that the closure of the interior is empty, but it is not nowhere dense; in fact it is dense in R, which is the opposite notion.
Every subset of a nowhere dense set is nowhere dense, and the union of finitely many nowhere dense sets is nowhere dense.
That is, the nowhere dense sets form an ideal of sets, a suitable notion of negligible set.

 Negligible set: Definition and Links by Encyclopedian.com - All about Negligible set
Neligible sets define several useful concepts that can be applied in various situations, such as truth almost everywhere.
This idea can be applied to any infinite set; but if applied to a finite set, every subset will be negligible, which isn't a very useful notion.
Let X be a topological space, and let a subset be negligible if it is of first category.

In mathematics, a negligible set is a set that is smallenough that it can be ignored for some purpose.
As common examples, finite sets can be ignored when studying the limit of a sequence, and null sets can be ignored whenstudying the integral of a measurable function.
In order for these to work, it's generally onlynecessary that the negligible sets form an ideal ; that is, the empty set is negligible,the union of two negligible sets is negligible, and any subset of a negligible set is negligible.

If set to 0 this effect is removed, but performance is increased without a noticeable drop in image quality.
If set to 0 such lighting is removed and while performance is improved the screen is almost completely fl from lack of this diffuse (ambient) lighting and hence is not recommended.
If set to 0, all areas of pre-rendered lighting will be blocky and unrealistic, but performance will be improved slightly at the cost of realism.

 Method and apparatus for extracting parameters for an electrical structure - US Patent 6106563   (Site not responding. Last check: 2007-10-07)
A set of network parameters is obtained that represents pure mode responses for the electrical structure (410).
The processor is responsive to the input 135 to process each distinct set of network description parameters to obtain mode specific model parameters, and to generate mode independent model parameters based on a combination of the respective mode specific model parameters.
Sets of network parameters are obtained which represent pure mode responses of an electrical structure, based on a definition of network parameters in which mode conversion responses of electrical structure are negligible, step 310.

 [FrSh:406]   (Site not responding. Last check: 2007-10-07)
In particular, several results depended on the fact that it is consistent to suppose that every countable relatively pointwise compact set of Lebesgue measurable functions is `stable' in Talagrand's sense; the point being that stable sets are known to have a variety of properties not shared by all pointwise compact sets.
In the present paper we present a model of set theory in which there is a countable relatively pointwise compact set of Lebesgue measurable functions which is not stable, and discuss the significance of this model in relation to the original questions.
A feature of our model which may be of independent interest is the following: in it, there is a closed negligible set Q subseteq [0,1]^2 such that whenever D subseteq [0,1] has outer measure 1 then the set Q^{-1}[D]= {x:(exists y in D)((x,y) in Q)} has inner measure 1.

 The Delaney Paradox And Negligible Risk
Under the FFDCA, EPA sets legally enforceable limits, or "tolerances", for pesticide residues that are expected to remain in or on foods treated with pesticides.
Tolerances are set for pesticide residues remaining in raw agricultural commodities under the provisions of section 408 of the FFDCA, while "food additive tolerances" are set for residues remaining in certain processed foods under section 409 of the FFDCA.
A uniform "negligible risk" rather than a "zero risk" standard for carcinogens in food, consistently applied, would best enable EPA to improve the overall safety of the food supply, and would result in only modest reductions in the benefits of pesticide use to farmers.

 Naturalistic Ethic
In other words, an almost-universal law is a law that would be universal if a negligible set of cases were ignored.
That is not to say that the negligible set should contain few situations, period; only a minute part of all possible situations.
It may be argued that those many situations are still within a negligible set compared to the totality of all situations in which it is theoretically possible to practice self-sacrifice, and thus self-sacrifice as a universal law is not moral.
