Software dynamic translation is the alteration of a running program to achieve a specific objective. For example, a dynamic optimizer uses software dynamic translation to modify a running program with the objective of making the program run faster. In addition to its demonstrated utility in dynamic optimizers, software dynamic translation also shows promise for producing applications that are a...

We develop a theory of tubular neighborhoods for the lower strata in manifold stratified spaces with two strata. In these topologically stratified spaces, manifold approximate fibrations and teardrops play the role that fibre bundles and mapping cylinders play in smoothly stratified spaces. Applications include the classification of neighborhood germs, the construction of exotic stratifications...

Let Fn denote the set of all mappings φ : {1, . . . , n} → {1, . . . , n} and assume that this set is equipped with the uniform distribution. Then a mapping φ ∈ Fn is usually called a random mapping. For our investigations it is convenient to represent random mappings by its functional graph Gφ, i.e. the graph consisting of the nodes 1, 2, . . . , n and of the edges (i, φ(i)), i = 1, . . . , n....

Denote by PolCn the space of all complex monic degree n polynomials in one variable and by PPn the product space PolCn×PolCn−1× . . . × PolC1 . Stratify the space PPn according to the multiplicities of the roots of the n polynomials and the presence of common roots between any two of them. Define the map π : PolCn →֒ PPn by P 7→ (P, P /n, P ′′/n(n− 1), . . . , P /n!). A stratum is called overdet...

kashafrud formation, siliciclastic strata, middle jurassic in age, commences with basal fluvio conglomerates. the strata are described in terms of 3 facies association (conglomerate, sandstone and mudstone), which were deposited in a fluvio-deltaic and turbities environments. the basal kashafrud strata at 2 areas (8 sections), in the eastern kopet-dagh basin, consist predominantly of boulder to...
