CERTAINTY, UNCERTAINTY, contracts. In matters of obligation, a thing is certain, when its essence, quality, and quantity, are described, distinctly set forth, Dig. 12, 1, 6. It is uncertain, when the description is not that of one individual object, but designates only the kind. Louis. Code, art. 3522, No. 8 5 Co. 121. Certainty is the mother of repose, and therefore the law aims at certainty. 1 Dick. 245. Act of the 27th of July, 1789, ii. 2, 1 Story's Laws, 6. His compensation for his servicer, shall not exceed two thousand dollars per annum. Gordon's Dig. art. 211.
     2. If a contract be so vague in its terms, that its meaning cannot be certainly collected, and the statute of frauds preclude the admissibility of parol evidence to clear up the difficulty; 5 Barn. & Cr. 588; S. C. 12 Eng. Com. L. R. 827; or parol evidence cannot supply the defect, then neither at law, nor in equity, can effect be given to it. 1 Russ. & M. 116; 1 Ch. Pr. 123.
     3. It is a maxim of law, that, that is certain which may be made certain; certum est quod certum reddi potest Co. Litt. 43; for example, when a man sells the oil he has in his store at so much a gallon, although there is uncertainty as to the quantity of oil, yet inasmuch as it can be ascertained, the maxim applies, and the sale is good. Vide generally, Story, Eq. El. Sec. 240 to 256; Mitf. Pl. by Jeremy, 41; Coop. Eq. Pl. 5; Wigr. on Disc. 77.

UNCERTAINTY. That which is unknown or vague. Vide Certainty.

A variety of methods have been proposed in recent years that, according to their proponents, can explore structural uncertainty, thereby giving a full accounting of forecast uncertainties. The most common method, which uses the results of multiple climate models from various research institutes, is based on the assumption that differences between the results of different climate models are a reasonable approximation of the structural uncertainty of a particular model as a representation of the real world.
Table II identifies the more detailed or micro-level types of uncertainties that must be dealt with when managing supply chains and dealing with information systems.
When plotting the relative standard uncertainties of the components graphically (Figure 4) it is obvious that the largest uncertainty was introduced from the effective cross-sectional area estimate ([A.sub.e]).
The three sources of uncertainty are combined by the propagation of uncertainties formula:
Substituting both of the input uncertainties of aerodynamics and output random response of motion into (1), the uncertain flutter equation can be rewritten as
Before embarking on the physical interpretations of the derived standard uncertainties in polar coordinate, geometric representation for the uncertainty of a complex-valued quantity (S = R + jI) is investigated as a region in the complex plane around its best estimate ([bar.S] = [bar.R] + j[bar.I]).
Evaluated standard uncertainties u([absolute value of S]) and u([PHI]) and the correlation coefficient [r.sub.pol] between [absolute value of S] and [PHI] in polar coordinate for Case 1.
In this case additional positioning uncertainties, which appear every three metres, were considered.
Following general good practices can help to reduce uncertainties in making measurements:
Furthermore, the studies--in each iteration (single model matching)--calculate the uncertainties and correlations of parameters based on LPU.
Our research focused on how more stringent instrument calibration requirements reduce the time needed to constrain cloud property uncertainties and, in turn, uncertainties in cloud feedback and anthropogenic radiative forcing.
