For some one-dimensional discrete-time autonomous population models, local stability implies global stability of the positive equilibrium point. One of the known techniques is the enveloping method. In this paper, we present a survey on the enveloping method to study global stability of single periodic population models. In the other words, we present the conditions in which “individual envelop...

eight faba bean genotypes and one local (barkat) as control were evaluated for three successive years (2000-2003) in a randomized complete block design (rcbd) with four replications at gorgan agricultural research station. this study was carried out to determine the morphological traits, yield components and yield stability to select the best genotypes. simple and combined analysis of variance ...

rust caused by phakopsora pachyrhizi syd. is a major constraint to soybean product in asia. early detection and possibilities of controlling plant diseases by the integration of several image processing methods has been the subject of extensive research. the main contribution of this paper is to present different methodologies for quantitatively detecting soybean rust at each stage of disease d...

Stability is one of the important issues for a TCP/AQM (Active Queue Management) system. In this paper, we study the local and global stability of TCP-newReno/RED under many flows regime. The existing results of the local stability are mostly for TCP-Reno, not for newReno. These results are obtained based on a small scale model with a few number of flows and thus cannot be blindly applied to a ...

Symbiosis, the collaboration of multiple organisms from different species, is widespread amongst prokaryotes. As symbiotic associations become more absolute, an inseparable union can result (symbiogenesis). This union would typically be considered a new unit of selection once a set of symbionts became reproductively inseparable. However we consider a macroevolutionary model within which new uni...

The unequal distribution of neurosurgical resources and diseases in the world contributes to inequality. Eight in ten neurosurgical cases needing essential neurosurgical care are found in low- and middle-income countries (LMICs); however, LMICs lack the neurosurgical resources to address these needs. Besides, where neurosurgical care is available, it is not financially accessible to the majorit...

Abstract: This paper considers local stability analysis of discrete-time Takagi-Sugeno fuzzy systems, for which classically in the TS literature only global stability is considered. Using a common quadratic and nonquadratic Lyapunov function, respectively, LMI conditions are developed to establish local stability of an equilibrium point. An estimate of the region of attraction of this point is ...

Text coherence evaluation becomes a vital and lovely task in Natural Language Processing subfields, such as text summarization, question answering, text generation and machine translation. Existing methods like entity-based and graph-based models are engaging with nouns and noun phrases change role in sequential sentences within short part of a text. They even have limitations in global coheren...
