This paper explores the spillover effect and trading volume of Financial, Technology, and FinTech Exchange Traded Funds (ETFs) by using ARMA-GARCH model. The study finds significant interconnectedness and interdependencies between these ETF sectors and the stock market index, indicating the transmission of shocks and volatility. Market fluctuations plays a crucial role in influencing the ETF sectors, with negative shocks impacting volatility more prominently.

The last few years have seen an exponential increase in the significance of the environmental agenda at the global level. Despite decades of research, the motivations that drive managers to engage in sustainable green practices remained uncertain. This study examines the degree to which value-belief-norm framework in explaining engagement in sustainable green practices. The data for this study was collected from 260 manufacturing SMEs and was analyzed by employing Structural Equation Modelling.

The paper "A supply chain optimization model for an enterprise based on maximizing the economic effect" is motivated by the importance of addressing the challenges faced by supply chain systems in the presence of multiple uncertain factors. It focusses on three crucial areas of innovative supply chain optimization models, including supply chain operations processes, competition and interactions in supply chains, and supply chain contracting and coordination.

In this research "Classification and regression tree model to predict the probability of a backorder in uncertain supply chain", we develop Classification and Regression Tree (CART) model that uses previously known parameters to predict the likelihood of a product being backordered. We also use different model parameters to evaluate the accuracy of the model. Result shows that the developed model can help decision makers to identify the key factors that lead to a product backordering.

In this study, a control system is proposed for the induction servomotor to achieve the highprecision speed tracking based on wavelet fuzzy cerebellar model articulation controller. In this proposed scheme, the wavelet fuzzy cerebellar model articulation controller (WFCMAC) is used to imitate an ideal controller due to it incorporates the advantages of the wavelet decomposition property with a fuzzy CMAC fast learning ability and the smooth compensator controller with bound estimation is designed to attenuate the effect of the approximation error caused by the WFCMAC approximator.

The intent of this book is to describe some recent data mining tools that have proven effective in dealing with data sets which often involve uncertain description or other complexities that cause difficulty for the conventional approaches of logistic regression, neural network models, and decision trees. We have organized the material into three parts. Part I introduces concepts. Part II contains chapters on a number of different techniques often used in data mining. Part III focuses on business applications of data mining.

The problem of guaranteed cost control in this paper for a class of two-dimensional (2D) systems is described by the Roesser model with multiplicative stochastic noises. A convex optimization problem with linear matrix inequality constraints is formulated to show the guaranteed cost controller which minimizes the guaranteed cost of the closed-loop uncertain systems.

This paper proposes a new method to compensate backlash by using Model Reference Adaptive Control (MRAC) and a nonlinear compensator without pre-determined backlash parameters. The adaptive controller assures the controllability of the different systems with uncertain parameters. While, the nonlinear compensator is used to overcome the effect of backlash.

This research focuses on the observer-based controller of a balancing robot. Firstly, the dynamic model of the robot is inferred. The uncertainty of the model parameters is then introduced as constraints in state space. Practically, it is very difficult to measure state variables as velocity and acceleration.

This paper focuses on a method of designing PD controller for a balancing robot-cart. The uncertainty of model parameters was introduced as constraints in state space. PD controller was designed through choosing Lyapunov function which was transformed by Kalman-Yakubovich-Popov lemma, a basic theoretical method based on frequency criterion.

Modelling the diffusion of mobile commerce in a country is a difficult task due to the non-linear, complex and uncertain nature of its operating environment. Conventional analytical techniques are of limited use in this context, and a System Dynamics approach is more appropriate to model such a complex system.

Recently, researchers have tried to integrate various dynamic information with static protein-protein interaction (PPI) networks to construct dynamic PPI networks. The shift from static PPI networks to dynamic PPI networks is essential to reveal the cellular function and organization. However, it is still impossible to construct an absolutely reliable dynamic PPI networks due to the noise and incompletion of high-throughput experimental data.
