In recent times, intuitionistic fuzzy sets introduced by Atanassov has been one of the most powerful and flexible approaches for dealing with complex and uncertain situations of real world. In particular, the concept of divergence between intuitionistic fuzzy sets is important since it has applications in various areas such as image segmentation, decision making, medical diagnosis, pattern reco...

We discuss the ground state energy, E(g), of some anharmonic oscillators p2 + x 2 _ 1 + P(x, g), where P(x, g) is a polynomial in x and g. Included is an example with a convergent perturbation series converging to the wrong answer and counterexamples to Dyson's argument on instability implying the divergence of perturbation theory and to the assertion that terms lower order in x to the same ord...

This paper proposes an independent component analysis (ICA) method using H∞ filters for nonminimum phase systems. In the basic ICA approach, the input signal is recovered by estimating the parameter of the inverse of the mixing system. If the system is nonminimum phase, the estimated parameter diverges due to the instability of the inverse. For this problem, a inverse filter is constructed base...

The commonly used Q-learning algorithm combined with function approximation induces systematic overestimations of state-action values. These systematic errors might cause instability, poor performance and sometimes divergence of learning. In this work, we present the AVERAGED TARGET DQN (ADQN) algorithm, an adaptation to the DQN class of algorithms which uses a weighted average over past learne...

If primordial fluctuation is Gaussian distributed, higher-order cumulants of the cosmic fields reflect nonlinear mode coupling and provide useful information of gravitational instability picture of structure formation. We show that their expected deviation (sample variance) from the universal values is nonvanishing even in linear theory in the case where observed volume is finite. As a result, ...

Cell growth, division, and death are defining features of biological tissues that contribute to morphogenesis. In hydrodynamic descriptions of cohesive tissues, their occurrence implies a nonzero rate of variation of cell density. We show how linear nonequilibrium thermodynamics allows us to express this rate as a combination of relevant thermodynamic forces: chemical potential, velocity diverg...

Studies on the evolutionary history of ascomycetes in terms of time scale will help to understand historical patterns that shape their biodiversity. Until now most of dating studies of ascomycetes have focused on major events in fungal evolution but not on divergence events within smaller groups of fungi e.g. within Sordariomycetes. We used molecular dating to estimate the time of separation of...

We study the stability of a thin membrane (of zero bending rigidity) with vortex sheet as nonlinear eigenvalue problem in parameter space mass (${R}_{1}$) and pretension (${T}_{0}$). With both ends fixed light membranes become unstable by divergence instability heavy lose flutter for ${T}_{0}$ that increases ${R}_{1}$. leading edge trailing free, or edges eigenmodes transition shape across boun...

this study utilizes a decade long (2005-2014) monthly data of total column tropospheric ozone (tcto) in dubson units to evaluate the spatial and temporal trend of lao over some major cities of west africa, namely lagos, accra, niamey, abuja, bamako, dakar, agadez, conakry, kano, and ouagadougou which are either capital cites or major commercial hubs, where the population ranges from 0.09 millio...

in this research, the frequency of the jet streams associated with extreme and pervasive precipitation has been analyzed using environmental to circulation approach. based on the 99th percentile index, 109 days of the extreme and pervasive precipitation was selected from the irimo data base ( including 33 synoptic, climatic and rain gage stations during 15992 days from farvardin, 1st, 1340 to d...
