In this paper, some important issues of granularity are discussed mainly in information systems (ISs) based on binary relation. Firstly, the vector representation method of knowledge granules is proposed in an information system based on binary relation to eliminate limitations of set representation method. Secondly, operators among knowledge granularity are introduced and some important proper...

In this paper, we propose a fast and effective mode decision (MD) algorithm based on rate distortion optimization (RDO) for AVS high definition video encoder. The fast algorithm is composed of two parts. Firstly, mode preselection based on sum of absolute difference (SAD) is employed to reduce modes for candidate so as to alleviate the dramatic throughout burden. Secondly, we adopt 4-way parall...

This paper seeks to investigate a new definition for architecture by unifying the three Vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. The paper is composed in two main sections. The first section investigates the nature of architecture based on the mentioned principles, where a...

In the last decade, interest in investigating sustainable employability (SE) of older workers has gained ground, generating a significant number theoretical and empirical contributions. However, construct SE lacks definition accepted by scientific community unified measurement criteria, which led to results that, so far, do not allow us draw solid conclusions on its relevance. The aim this inte...

Abstract Under the Brownian motion environment, adaptive synchronization is mainly studied in this paper for fractional-order stochastic neural networks (FSNNs) with time delays and discontinuous activation functions. Firstly, an existence theorem of solutions established global FNNs are obtained under definition Filippov solution by using fixed-point a condensing map. Secondly, controller desi...

This article aims to discuss the crime of "pig-butchering scams" in securities market and its legal regulation. First, introduces definition harmfulness. Secondly, analyses current regulations on China. It points out problems, such as bottlenecks applying laws difficulty collecting evidence. Finally, suggests improving regulations, strengthening supervision reducing investor information asymmet...

In this paper we consider optimal control problems in which a certain L1-type norm of the control appears in the objective. Problems of this type are of interest for at least two reasons. Firstly, the L1 norm of the control is often a natural measure of the control cost. Secondly, this term promotes sparsely supported optimal controls, i.e., controls which are zero on substantial parts of its d...

This paper contains some reflections about using 3D topology, and more generally some 3D concepts related to 3D cadastre. Firstly, we develop some conceptual views about 3D modelling and more specifically about the definition of 3D spatial objects. Secondly, we present a new framework for representing spatial relationships. The framework has different “complexity” levels and allows mixing simpl...

Enterprises are embracing cloud computing in order to reduce costs and increase agility in their everyday business operations. Nevertheless, due mainly to confidentiality, privacy and integrity concerns, many are still reluctant to migrate their sensitive data to the cloud. In this paper, firstly, we outline the construction of a suitable Context-aware Security Model, for enhancing security in ...
