Efficient change control and configuration management is imperative for addressing the emerging security threats in cloud infrastructure. These majorly exploit misconfiguration vulnerabilities e.g. excessive permissions, disabled logging features publicly accessible storage buckets. Traditional tools mechanisms are unable to effectively continuously track changes infrastructure owing transience...

While multi-agent systems have been successfully applied to combinatorial optimization, very few works concern their applicability to continuous optimization problems. In this article we propose a framework for modeling a continuous optimization problems as multi-agent system, which we call NDMO, by representing the problem as an agent graph, and complemented with optimization solving behaviors...

This paper describes a fully functional prototype of a multi-component system that allows users to retrieve, store and search documents from a variety of publicly available information sources, in a variety of languages, on any subject domain users may be interested in. The system integrates a crawler, which selects and downloads potentially relevant documents, a cleaning tool which removes irr...

Active authentication is the process of continuously verifying a user based on their on-going interaction with a computer. In this study, we consider a representative collection of behavioral biometrics: two low-level modalities of keystroke dynamics and mouse movement, and a high-level modality of stylometry. We develop a sensor for each modality and organize the sensors as a parallel binary d...

Ant Colony Optimization (ACO) algorithms are basically developed for discrete optimization and hence their application to continuous optimization problems require the transformation of a continuous search space to a discrete one by discretization of the continuous decision variables. Thus, the allowable continuous range of decision variables is usually discretized into a discrete set of allowab...

the morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (felis catus). the eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. results showed that the general structure of photoreceptor layer in this...

Mesh adaptation is considered here as the research of an optimum that minimizes the P1 interpolation error of a function u of R given a number of vertices. A continuous modeling is described by considering classes of equivalence between meshes which are analytically represented by a metric tensor field. Continuous metrics are exhibited for L error model and mesh order of convergence are analyze...

This paper presents a new approach for continuous tracking of moving objects observed by multiple fixed cameras. The continuous tracking of moving objects in each view is realized using a Tensor Voting based approach. We infer objects trajectories by performing a perceptual grouping in 2D+t using Tensor Voting. Also, a multi-scale approach bridging gaps in object trajectories is presented. The ...
