Unary function

There are other methods of augmenting schemes which may or may not increase the power of the language in certain cases. For example one can add constants or resets - zero-placed functions. One can also consider the effect of adding an equality test - a special two place predicate, say E(x,y) - which is restricted to be interpreted as equality - E(x,y) is true if and only if x = y. Yet another is to add a counter which as we shall see later means adding special unary functions and predicates which are always restricted to be interpreted as +1, -1 or test... [Pg.23]

A unary function. Fi(ri) is the simplest radial distribution function... [Pg.166]

Interval analysis is an extension of real analysis that allows computations with intervals of reals instead of reals. Common operations and unary functions are extended for interval operands. For instance, [1,2] + [3,6] results in the interval [4,8], which encloses all the results from a point-wise evaluation of the real arithmetic operator on all the values of the operands. In practice these extensions simply consider the bounds of the operands to compute the bounds of the result, since the involved operations are monotonic. [Pg.2271]

Concave additive unary terms are replaced by a linear underestimating function that matches the term at the bounds of the subre-gion. [Pg.66]

Once the unary and binary potentials, which describe interactions in the wall-ion system, are specified, distribution of ions near the wall, and between slabs can be calculated. We will further employ an approximation based upon the distribution function formalism, but first the definitions of equilibrium ion densities and corresponding distribution functions have to be introduced. [Pg.450]

Unary phase diagrams are two-dimensional graphs that display the phases of singlecomponent systems (e.g. elements) as a function of both temperature (abscissa) and pressure (ordinate). Since there is only one component, it is not necessary to specify composition. Figure 11.2 shows the phase diagram for sulfur, which exists in two allotropes at 1 atm of pressure, rhombic (T < 368 K) and monoclinic T > 368 K). [Pg.472]

In this paragraph shortly the permeation measurement method is introduced, followed by various examples of permeation through a silicalite-1 membrane on a sintered stainless steel support. This includes unary and binary mixtures as a function of partial pressure, composition and temperature. Finally the present state of modelling permeation through silicalite-1 membranes is reviewed. [Pg.433]

Note that some operations, like NOT, work on a single number they re called unary. Most need two numbers and are called binary functions. Plus and minus signs can be either unary (in the number —3, the minus sign works on a single number) or binary (the minus sign connects two numbers in the expression 10 — 6). [Pg.34]

For a function /with integer inputs and integer outputs, an algorithm is said to compute/in unary iff it is a normal algorithm (i.e., not restricted to unary representation in its own computations) that expects each input in unary and computes the result in unary. For instance, if / has two inputs k and algorithm computes l / > ) from ( 1 1 °). This notation is used for transformations of security parameters. [Pg.39]

A function len N N, called the length function (denoting the length of the hash values in terms of the security parameter), and a polynomial-time algorithm that computes len in unary. [Pg.251]

One may want the hash function to reduce the message length by more than the 1 or 2 bits required above. Hence let a monotonically increasing function /e o be given, which is to be approximated by len from below. A polynomial-time algorithm that computes len in unary and a value g N are also needed such that for all k >... [Pg.267]

The function len is defined by len k ) = length make small(k )), as explained above, and the polynomial-time algorithm that computes it in unary is the composition of those for length and make small. The value that denotes from where on the hash functions are length-reducing is ki . [Pg.269]

The function len is identical to length from the given fixed-length encoding, and so is the algorithm to compute it in unary. [Pg.281]

Construction 8.68. Let a function tau N —> N and a pol)momial-time algorithm that computes tau in unary be given. The corresponding family of iterated squaring and doubling as hiding homomorphisms has the following components ... [Pg.286]

The objective of this section is much less ambitious and can be formulated as follows If the free-energy function for all phases in a given system were known as a function of temperature and composition, how could one construct the corresponding phase diagram In other words, what is the relationship between free energies and phase diagrams Two examples are considered below polymorphic transformation in unary systems and complete solid solubility. [Pg.258]

A phase diagram is a map that indicates the areas of stability of the various phases as a function of external conditions (temperature and pressure). Pure materials, such as mercury, helium, water, and methyl alcohol are considered one-component systems and they have unary phase diagrams. The equilibrium phases in two-component systems are presented in binary phase diagrams. Because many important materials consist of three, four, and more components, many attempts have been made to deduce their multicomponent phase diagrams. However, the vast majority of systems with three or more components are very complex, and no overall maps of the phase relationships have been worked out. [Pg.2150]

Based on these notions, we could describe the functioning of definite description forming operators, such as the jota-operator, when applied to a predicate that signifies a unary property with only one instance, as a function which takes what is determined by a PS to what satisfies the PS. [Pg.99]

Bubbles are a rather spectacular embodiment of the forces produced by surface tension. Their spherical shape is a testimony to the isotropic nature of the gas/liquid interfacial tension. Of all the forces involved in shaping and making bubbles, surface tension is preeminent, and this dominant position is reinforced by the appearance of the surface tension to the third power in the exponential in the rate expression for bubble nucleation as shown in Eq. (6). In this review, the author has chosen to emphasize a property of gas bubbles that has been noted in the past, but whose implications have not been fully worked out that the surface tension is a function of the bubble size. This is not true for cavitation or boiling in unary liquids. [Pg.490]

To do this, the program first discovered a separate causal explanation for the positive/negative differentiation for each rule. In the first rule the stability was determined to be a function of the steric hindrance between the two end-groups of the small chain. However, such a single unary rule was inadequate... [Pg.60]

The mobile epoxy groups located in the loops/tails of the adsorbed PGMA macromolecule are shown to be accessible to the functional groups of an end-functionalized polymer and thus available for grafting. The mobility of the loops/tails of PGMA could be also effectively used to develop a novel system, which is robust, and possesses wettability on demand. In fact, the responsive unary polymer brush (UPB) system described below benefited from the mobility of the PGMA loops effectively to switch surface properties. ... [Pg.462]
