A generalized definition of a frame of reference in spaces with affine connections and metrics is proposed based on the set of the following differential-geometric objects: (a) a non-null (non-isotropic) vector field, (b) the orthogonal to the vector field sub space, (c) an affine connection and the related to it covariant differential operator determining a transport along the given non-null v...

Deviation equation of Synge and Schild has been investigated over dif-ferentiable manifolds with contravariant and covariant affine connections (whose components differ not only by sign) and metric [(Ln, g)-spaces]. It is shown that the condition £ ξ u = 0 for obtaining this equation is only a sufficient (but not necessary) condition. By means of a non-isotropic (non-null) vector field u [g(u, ...

Healthcare systems nowadays depend on IoT sensors for sending data over the internet as a common practice. Encryption of medical images is very important to secure patient information. Encrypting these consumes lot time edge computing; therefore, use an auto-encoder compression before encoding will solve such problem. In this paper, we compress image encryption, and encryption output (vector) s...

We introduce TRAAM, or Transduction RAAM, a fully bilingual generalization of Pollack’s (1990) monolingual Recursive Auto-Associative Memory neural network model, in which each distributed vector represents a bilingual constituent—i.e., an instance of a transduction rule, which specifies a relation between two monolingual constituents and how their subconstituents should be permuted. Bilingual ...

Service-oriented architectures (SOA) and, in particular, Web Services designs are widely adopted for the development of interoperable systems. In a dynamic scenario, a composed service may exploit component services in order to complete its task; composed services are variously distributed, and offered by different providers in different security domains and under different load conditions. So,...

The relationship between exports, imports and economic growth of Ethiopia has been investigated in this paper for the period 1981-2018 by using annual data from World Bank. For analysis, Vector Auto Regressive Model, Johansen co-integration analysis Granger-Causality tests were implemented. outcome reveals that there is no relation Ethiopia. Conversely, we found a strong evidence bidirectional ...
