In this paper, we review Icarus, a cognitive architecture that utilizes hierarchical skills and concepts for reactive execution in physical environments. In addition, we present two extensions to the framework. The first involves the incorporation of means-ends analysis, which lets the system compose known skills to solve novel problems. The second involves the storage of new skills that are ba...

This paper employs Data Envelopment Analysis to measure for the first time the performance of Greek domestic equity mutual funds over four different one-year horizons and for the whole four-year period. In particular, the model used examines whether fund managers employ inputs (i.e. assets, loads, and risk) efficiently to produce output (returns). The results demonstrate that the efficient fund...

In this paper, we are concerned with approach solutions for Sturm–Liouville problems (SLP) using variational problem (VP) formulation of regular SLP. The minimization (MP) is also set forth, and the connection between solution each then proved. Variational estimations (the equation associated through Euler–Lagrange principle Nehari’s method, shooting method bisection method) iterative methods (...

the principle of formality –free protection is an international principle in the copyright and it was stabilized in the berne convention. but this principle has not been studied in iran and evaluation of the principle is very vital because easier access to the works and fair trial. recent paper has attempted to study this principle in light of the berne convention and analyzes and interprets th...

Abstract Hyperbolic nonlocal theory is applied in this paper to calculate deflections functionally graded nanobeams under uniform load. The developed using the work done principle conjunction with Eringen’s theory. Free stress conditions on upper and lower surfaces are achieved by current hypothesis. Deflection of beam estimated Navier’s approach considering simple ends nanobeam. Solutions foun...

conclusions since telomerase is expressed in 90% of cancer cells, its inhibition can be considered as a goal of cancer treatment. results about 90% of cancers need a high level of this enzyme to continue cell multiplication. since this enzyme set is absent in normal cells, or present at a very low level, use of telomerase inhibitors cannot have significant effects on normal cells. evidence acqu...

We describes a framework in which to view the end-to-endindependently-verifiable (E2E) voting systems based on mixnets. We use the framework to invent new systems that combine front and back-ends from existing systems.
