Ways to improve the sensitivity and signal-to-noise ratio of primary converters in each case have their fundamental and practical limitations. To determine the optimal frequency of the electromechanical conversion and ensure the specified accuracy and stability of metrological characteristics are encouraged to use the method of probabilistic stability studies of the output characteristic of the converter. The research is based on the methods of the stability characteristics of the probabilistic stability studies, provides the most comprehensive account of the random nature of the structural abnormalities and electrical parameters under the influence of destabilizing factors in serial production. Formed the basis of the method of moments technique allows for a small amount of calculations to obtain the necessary accuracy.

This study presents on-the-fly identification and multi-step prediction of nonlinear systems with delayed inputs using a dynamic neural network combined with a smooth projection onto ellipsoids. The projection enforces parameter constraints that guarantee stability, while a Lyapunov–Krasovskii analysis yields computable ultimate error bounds. Riccati-type matrix inequalities are derived, providing an efficient vectorization–projection–devectorization implementation suitable for ...

Two-dimensional C60 carbon allotropes have gained much attention since their first synthesis in 2022, but many of their thermophysical and mechanical properties remain unreported in the literature. In this article, we performed a high-temperature molecular dynamics study of quasi-hexagonal (qHP) and quasi-tetragonal (qTP) C60 phases using the modern machine-learning interatomic potential GAP-20. We show that, ...

Traditionally, Delhi’s markets are oversaturated spaces for sensory perception: a cacophony of sounds, contrasting smells, and a vivid visual cascade. This study adopts a sensitive ethnographic lens to examine how bodily sensations relate to sociality, of- fering insight into the social order of the marketplace and an individual’s position within it. What markers evoke comfort ...

In this work, we propose a ratio-dependent intraguild predation model that incorporates fear and gestation delay. Further, the cost of the intraguild predator's fear is thought to decrease the size of the intraguild prey. The interaction between prey and predator takes place in the form ratio-dependence type. This type of functional response offers a valuable ...

Fear and prey refuges are two significant topics in the ecological community because they are closely associated with the connectivity of natural resources. The effect of fear on prey populations and prey refuges (proportional to both the prey and predator) is investigated in the nonlinear-type predator-harvested Leslie–Gower model. This type of prey refuge is much ...

This paper deals with the investigation of the three species food-web model. This model includes two logistically growing interaction species, namely x and y, and the third species z behaves as the predator and also host for x. The species z predating on the species y with the Holling type-II functional response, while the first species x is benefited from the third species z. Further, the effect of ...

In this article, we discuss the dynamics of a Leslie–Gower ratio-dependent predator–prey model incorporating fear in the prey population. Moreover, the Allee effect in the predator growth is added into account from both biological and mathematical points of view.

Dynamical analysis of a delayed tri-trophic food chain consisting of prey, an intermediate, and a top predator is investigated in this paper. The additive Allee effect is introduced in the prey population, and it is assumed that there is a time lag due to the gestation effect in the intermediate predator. The interference among the ...
