Global warming arising from climate change can increase the spread of deadly diseases. Effort is needed to develop a set of policies for the government to stem or reduce health risks from global warming. The purpose of this paper is to examine more detail and comprehensively about the relationship among climate and event disease count in Taiwan using the partial least square latent regression model. The results obtained that of the 17 types of diseases in Taiwan, that has the most significant loading factor is Amoebiasis, Malaria and Chikungunya. At the same time, climate variables that have the biggest most significant factor are Number day with max temp more than 30, Number day Temp more than 25, and Rainfall PH. Cronbach’s Alpha infectious disease 0.9696 and climate 0.2813. At the same time, the value of Dillon Goldstein’s rho infectious disease 0.974 and climate 0.6404, respectively.
We investigate a privacy-signaling game problem in which a sender with privacy concerns observes a pair of correlated random vectors which are modeled as jointly Gaussian. The sender aims to hide one of these random v...

This work presents an algorithm to automatically translate a Blocking Flexible Job Shop Scheduling Problem modeling into automata using the Supervisory Control Theory. Different problems of the literature are analyzed in their textual form and the algorithm returns an automaton that implements the closed-loop behavior under the Supervisory Control Theory. A heuristic is applied to find, among all sequences, the sequence that minimizes the makespan. With our approach, we find makespan values near to those in the literature. This methodology faces memory usage boundaries, but it was able to find solutions for instances of some well-known problems.
We present a new experimental design procedure that divides a set of experimental units into two groups in order to minimize error in estimating an additive treatment effect. One concern is minimizing error at the exp...

In this paper, we propose and solve a novel Brinkman–triple-porosity–permeability model to describe fluid flow between filled conduits, matrix, micro-caves, and micro-fractures. The flow in triple-porosity media, consisting of three porosity types as matrix, micro-caves, and micro-fractures, is described by a fully coupled triple-porosity model, which removes the stated assumptions of sequential flow and allows direct communication of fluid between different porosity types. The flow within the conduits is described by the Brinkman equation to capture the viscous flow effects that may occur when the free-flow region is occupied by proppants or rock particles. Based on the fundamental properties of the Brinkman model and the triple-porosity model, five physical interface conditions are proposed at the interface between the porous medium and the pipe. The spatial discretization is performed using a discontinuous Galerkin method, while temporal discretization is performed using the backward Euler method. The paper proposes both a semi-discrete scheme and a fully discrete scheme, and establishes the stability of these schemes. Optimal error estimates are subsequently derived. The validity of the model is confirmed through three numerical experiments, which also explore the characteristics of the numerical method, including optimal convergence rates for different mesh types and numerical formats. Additionally, fluid flow simulations are conducted in a complex porous medium region, and two applications are demonstrated in a multi-stage hydraulically fractured horizontal wellbore, connecting a vertical production casing to a cased-hole completion.
