The heterogeneity of multiple radio access technologies (RATs) is a key characteristic for next generation mobile network (NGMN) as there is no single existing legacy RAT that provides ubiquitous services to mobile users. Therefore, the problem for mobile services over heterogeneous networks lies in how the on-going sessions can be maintained using seamless handover when a mobile node (MN) move...

Wireless Sensor Networks (WSNs) is temporarily formed, operated and managed by the nodes themselves. In a complex WSN, malicious nodes are well disguised, and they can attack the entire network on specific purpose by utilizing the natural cooperation of nodes. The error-prone characteristic of sensor nodes can also cause instability in WSN. Therefore, how to choose one or more suitable sensor n...

We study sequences of infinitely near T -points of a smooth family F/Y of geometrically irreducible surfaces. We destinguish a special sort of such sequences, the strict sequences. To each one, we associate an ordered unweighted Enriques diagram. We prove that the various sequences with a given diagram form a functor, and we represent it by a smooth Y -scheme. We equip this scheme with a free a...

Abstract: A multi-variable Golden-Section adaptive controller is proposed for the tracking control of robotic manipulators with unknown dynamics. With a small sample time, the unknown dynamics of the robotic manipulator are denoted equivalently by a characteristic model of a 2-order multivariable time-varying difference equation. The coefficients of the characteristic model change slowly with t...

The Coefficient Diagram Method (CDM) is a parametric approach to design a controller based on coefficient shaping. It involves two steps; first, characterization of the desired time response in terms of the two specific parameters denoted by (αi, τ), in this paper, that are functions of a characteristic polynomial. Once such a target characteristic polynomial is obtained, the controller paramet...

Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...

Forming effective coalitions is a major research challenge in AI and multi-agent systems. Thus, coalitional games, including coalition structure generation, have been attracting considerable attention from the AI research community. Traditionally, the input of a coalitional game is a black-box function called a characteristic function. In this paper, we develop a new concise representation sche...

In this paper, a novel watermarking method is presented based on the concept of communications with side information. We investigate the characteristic of mean filtering to formulize the problems of watermark embedding and extraction. This leads to a non-additive embedding strategy and a sophisticated blind detection mechanism. With regard to geometric attacks (without cropping), block-based wa...

In this talk we propose a numerical scheme to investigate the stability of steady states of the nonlinear Gurtin–MacCamy system which is a basic model in population dynamics. In fact the analysis of stability is usually performed by the study of transcendental characteristic equations that are too difficult to approach by analytical methods. The method is based on the discretization of the infi...
