Consider a continuous flow of automorphisms of a G-principal bundle which is chain transitive on its compact Hausdorff base. Here G is a connected noncompact semi-simple Lie group with finite center. The finest Morse decomposition of the induced flows on the associated flag bundles were obtained in previous articles. Here we describe the stable sets of these Morse components and, under an addit...

1. Let [qo, qi,q2, ■ • ■ J be a Kleene enumeration of partial recursive functions. If / is such a function, denote by 9f its index set, 9f= {ra|g„^/}. Insofar as the indices of a partial recursive function correspond to the different sets of "instructions" for computing its values, it is natural to ask how much of the "complexity" of the function is reflected by its index set; for example, one ...

An important component of parallel programs with distributed data structures is local address generation for various index patterns. In this paper we present a general approach as well as two speci c algorithms for common problems to perform this task quickly on distributed arrays. Our algorithms usually run in O(joutputj) time, which is optimal. We have implemented our algorithms. When the pro...

In the context of globalization of economic development processes, the issue of determining the level of public welfare of economic agents is particularly burning. The object of ehis study is the process of assessing welfare of the economic entities system. The subject of the study is the instrumental and mathematical aspects of modeling and measuring the public welfare. The aim of the work is ...

In many real-life problems, we are often faced with manipulating families of sets. Manipulation of large-scale set families is one of the important fundamental techniques for web information retrieval, integration, and mining. For this purpose, a special type of binary decision diagrams (BDDs), called Zero-suppressed BDDs (ZDDs), is used. However, current techniques for storing ZDDs require a h...

We study generalizations of shortest programs as they pertain to Schaefer’s MIN∗ problem. We identify sets of m-minimal and T-minimal indices and characterize their truth-table and Turing degrees. In particular, we show MIN ⊕ ∅′′ ≡T ∅′′′, MIN (n) ⊕ ∅(n+2) ≡T ∅(n+4), and that there exists a Kolmogorov numbering ψ satisfying both MINψ ≡tt ∅′′′ and MIN (n) ψ ≡T ∅(n+4). This Kolmogorov numbering al...

The objective of this thesis is to develop a user friendly web application that will be used to analyse data sets using various machine learning algorithms. The application design follows human computer interaction design guidelines and principles to make a user friendly interface [Shn03]. It uses Linear Regression, Logistic Regression, Backpropagation machine learning algorithms for prediction...

thyme essential oils (eo) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. it is also used for flavoring and preservation of several foods. nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. in this study thymus ...

the field of nanobiotechnology mainly encompasses with physics, biology, chemistry and material sciences and it develops novel therapeutic nano-scale materials for biomedical, drug delivery, cancer therapy and pharmaceutical applications. silver nanoparticles (agnps) have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications, so ag...

symmetric division deg index is one of the 148 discrete adriatic indices that showed good predictive properties on the testing sets provided by international academy of mathematical chemistry.symmetric division deg index is defined by$$sdd(g) = sume left( frac{min{d_u,d_v}}{max{d_u,d_v}} + frac{max{d_u,d_v}}{min{d_u,d_v}} right),$$where $d_i$ is the degree of vertex $i$ in graph $g$.in this pap...
