Two-compartment stochastic single vehicle routing problems with simultaneous pickups and deliveries from N ordered customers

Abstract: We consider a vehicle with two compartments that starts its route from a depot and visits N ordered customers in order to deliver new (or fresh or useful) products and to collect old (or expired or...

Epidemiological Diffusion and Discrete Branching Models for Malware Propagation in Computer Networks

Abstract: This paper focuses on the study of epidemiological diffusion and discrete branching models for malware propagation in computer networks.

Equivalence relation between multiresolution analyses of L2(R)

Abstract: This paper is concerned with the development of an equivalence relation between two multiresolution analyses of L2(R). The relation called unitary equivalence is created by the action of a unitary operator in a way that the multiresolution structure and the decomposition and reconstruction algorithms remain invariant. A characterization in terms of the scaling functions of the multiresolution analyses is given. Distinct equivalence classes of multiresolution analyses are derived. Finally, we prove that B-splines give rise to non- equivalent examples.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.

Drift instabilities' interaction: A tightening of the B-direction component on the amplitude of the azimouthally propagating wave

Abstract: Abstract A suitable modification on the plasma production device makes the plasma column length changeable; the axially propagating wave strikes on the movable circular base of the cavity and the reflected wave is affected enough. A tightening on the azimouthally propagating wave makes the amplitude measurements precarious, and the previous experimental results for fixed cavity length are valid. A strong boundaries' influence on the instability's reinforcement makes clear the need to extend even more the thermonuclear reactor's dimensions. In the present paper, an extended research of plasma parameters has been carried out, a corresponding theoretical model is developed to explain the phenomena and the comparison to the simulated results has been confirmed.

Security and Formation of Network-Centric Operations

Abstract: After giving definitions and background information of key terms, we report and analyze the multi-layer graph model of network centric operations (NCOs), and we mention its advantages. Moreover, we investigate security problem of NCOs by applying methods of vertex pursuit games. Finally, in Sect. 6 we take up with the problem of network centric warfare strategic formation.
