The magnetic properties were investigated for C- and P-implanted MgO single crystals, which irradiated by 80 keV C P ions with the dose of 3 × 1017 ions/cm2. pristine apparently changed ion implantation. Room temperature ferromagnetism was presented in C-implanted sample, while sample only displayed paramagnetism at 20 K. For purpose clarifying correlation between microstructure, a comparative ...

Al~tract--By employing the second-order Noether's theorem, several new invariant integrals have been derived for the non-linear shallow shell--the Marguerre-von K~irm~in shell. The dynamic effect is considered in the derivations. These invariant integrals are path-independent over the projection image of the middle surface of the shell in a Cartesian plane, in which the projection area of the m...

option of defect is one of common options between sale and rent contracts, however, it has special rules and conditions in those contracts. in the sale contracts, any defect in the sold or bought thing causes the victim has option of defect but in the rent contracts, only the defect creates option of defect that causes hardship in using of goods or reducing of benefits. in the sale, defect of s...

Previously, a nonlinear autoregressive network with exogenous input (NARX) demonstrated an excellent performance, far outperforming established method in optimal baseline subtraction, for defect detection guided wave signals. The principle is to train NARX on defect-free signals obtain filter that predicts the next point from previous points signal. trained then applied new measurement and outp...

This paper describes a framework for partitioning programming sessions – including coding, browsing, thinking, reading, testing, etc. – in programming episodes of five seconds’ to a few minutes’ duration. It is based on interpreting excerpts of a session via annotating activity types, properties, triggering events, and focus of attention. The set of predefined activities is grounded on about th...

1. Introduction Prediction uncertainty is the likely discrepancy between model predictions and the actual, unrealized system responses. Contributions to uncertainty include solution error and limited capabilities of numerical models, error and deficiency of data, and errors in system conceptual models. Uncertainty can be reduced by improving numerical models and using numerical models, data, an...

MANET is a collection of mobile nodes operated by battery source with limited energy reservoir. The dynamic topology and absence of pre-existing infrastructure in MANET makes routing technique more thought-provoking. The arbitrary movement of nodes may lead towards more packet drop, routing overhead and end-to-end delay. Moreover power deficiency in nodes affects the packet forwarding ability a...

We present an approach to studying directed polymers in interaction with a defect line and subject to a force, which pulls them away from the line. We consider in particular the case of inhomogeneous interactions. We first give a formula relating the free energy of these models to the free energy of the corresponding ones in which the force is switched off. We then show how to detect the presen...

Abstract: The paper studies the problem of finite time formation control for multiple vehicles based on the motion planning approach. The vehicle is modeled as the full actuated rigid body with the dynamics evolving on the tangent bundle of Euclidean group, both the formation time which is finite and the geometric structure of the formation are assumed to be specified by the task. For the requi...
