In this paper, we establish the existence of at least one positive solution for the higher order boundary value problems on time scales by using the Krasnoselskii fixed point theorem.

We determine intervals for two eigenvalues for which there exists no positive solution of a system of nonlinear multi-point dynamic equations on time scales

Hydrological responses are being impacted by both climate change and human activities. In particular, climate change and regional human activities have accelerated significantly during the last three decades in South Korea. The variation in runoff due to ... see more

This paper determines the designing of a non-fragile H8 output feedback controller for a class of nonlinear uncertain dynamical systems with multiple timescales described by a Takagi-Sugeno (TS) fuzzy model. Based on a linear matrix inequality (LMI) appro... see more

Abstract: This study aims to make a diagnostic analysis of seasonal and annual precipitation in different scales of time and relate them to atmospheric mechanisms that operate in different regions of the Maranhão State. For this we applied the methodology... see more

The new coronavirus (COVID-19) has spread to over 200 countries, with over 36 million confirmed cases as of October 10, 2020. As a result, numerous machine learning models capable of forecasting the epidemic worldwide have been produced. This paper review... see more
