Database replication is a way to increase system performance and fault-tolerance of a given system. The price to pay is the effort needed to guarantee data consistency, and this is not an easy task. In this paper, we introduce a description of two 1-Copy-Serializable (1CS) [14] eager update everywhere replication protocols. The preliminary results of their implementation in the XXXXX middleware...

Though numerous research challenges in security focus on MANET, the need for design based secure Group Communication Systems (GCSs) is always a major constraint. The constraint is felt towards incorporation of group based multi-hop security for variable services which requires resource constraints. SKEMA adopts Clique based graph theoretic approach to detect node activity and identifying neighb...

The problem of inferring proteins from complex peptide samples in shotgun proteomic workflow sets extreme demands on computational resources in respect of the required very high processing throughputs, rapid processing rates and reliability of results. This is exacerbated by the fact that, in general, a given protein cannot be defined by a fixed sequence of amino acids due to the existence of s...

The use of Internet Things (IoT) technology for real-time monitoring agricultural pests is an unavoidable trend in the future intelligent agriculture. This paper aims to address difficulties deploying models at edge pest visual system and low recognition accuracy. In order achieve that, a lightweight GCSS-YOLOv5s algorithm proposed. Firstly, we introduce network GhostNet, Ghostconv module repla...

Many studies, even those conducted in the field of Americas, still argue that graphic communication necessarily builds on coding units speech. However, recent years, there has been a growing awareness narrowness this concept by focusing Indigenous and pre-Columbian societies, who favore(d) non-glottographic systems over written This paper concerns development semiological multidimensional theor...

In order to study air traffic control of UAS’s (Unmanned Aerial Systems) in very low altitudes, the UTM (UAS Traffic Management) simulator has be as flexible and expandable other research simulators because relevant technologies regulations are not matured enough at this stage. Available approaches using open sources platforms investigated used simulator. The fundamental rationale for selection...

Unmanned aerial vehicle (UAV) collaboration has become the main means of indoor and outdoor regional search, railway patrol, other tasks, navigation planning is one key, albeit difficult, technologies. The purpose UAV to plan reasonable trajectories for UAVs avoid obstacles reach task area. Essentially, it a complex optimization problem that requires use algorithms search path-point solutions m...

Contraction theory is a powerful tool for proving asymptotic properties of nonlinear dynamical systems including convergence to an attractor and entrainment to a periodic excitation. We consider three generalizations of contraction with respect to a norm that allow contraction to take place after small transients in time and/or amplitude. These generalized contractive systems (GCSs) are useful ...
