efficiency of numerical methods is an important problem in dynamic nonlinear analyses. it is possible to use of numerical methods such as beta-newmark in order to investigate the structural response behavior of the dynamic systems under random sea wave loads but because of necessity to analysis the offshore systems for extensive time to fatigue study it is important to use of simple stable meth...

evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...

In this thesis, we address the problem of optimistic replication for collaborative text editing in Peer-to-Peer (P2P) systems. This problem is challenging because of concurrent updating at multiple peers and dynamic behavior of peers. Operational transformation (OT) is a typical approach used for handling optimistic replication in the context of distributed text editing. However, most of OT sol...

G? = (4 E c* : II d II < PI. I f ~(a) is defined and continuous on [t q, t], we will write xt for the function for which x~(s) = x(t + S) for s E [-q, 01. Hence xt E C, . This paper shows that for a nonlinear one-dimensional differential delay equation a(t) = F;(t, x1(.)) (DDE) one can frequently determine (almost by inspection) if the 0 solution is asymptotically stable and give a region of at...

Evolution is a process that is influenced by various environmental factors, e.g. the interactions between different species, genes, and biogeographical properties. Hence, it is interesting to study the combined evolutionary history of multiple species, their genes, and the environment they live in. A common approach to address this research problem is to describe each individual evolution as a ...

Abstract The fields of viral ecology and evolution are rapidly expanding, motivated in part by concerns around emerging zoonoses. One consequence is the proliferation host–virus association data, which underpin macroecology zoonotic risk prediction but remain fragmented across numerous data portals. In present article, we propose that synthesis a central challenge to characterize global virome ...

This paper discusses the state of the art in data reconciliation and instrumentation upgrade. In the field of data reconciliation, several new directions of research and recommendations for software vendors as well as practitioners are made. In the case of the emerging field of instrumentation upgrade, aside from also pinpointing research and development directions, practical economical aspects...
