The study examines the effect of financial leverage and dividend payments on firm value using a sample of 29 listed real estate firms from the Ho Chi Minh Stock Exchange (HOSE) and the Hanoi Stock Exchange (HNX). By employing the Ordinary Least Square (OLS), Two-stage Least Square (2SLS), and Generalized Method of Moments (GMM) estimation methods, we obtain robust evidence of the positive effect of leverage and dividend distribution on real estate sector corporate value.

In this paper, a point-to-point positioning controller based on Active Disturbance Rejection Control (ADRC) is applied to a linear motion actuator using lead ball screw. In the design, the Extended State Observer (ESO) is adopted to the controller structure, and the ADRC is designed which consists of the ESO and the nonlinear PD controller to estimate and compensate the disturbances.

This research proposes a new method to synthesize a robust observer for the polynomial systems in the presence of the uncertainties. Here, a special mathematical transformation is carried out to convert the uncertain polynomial systems into the unknown input polynomial systems and then the robust observer is designed for estimating the state variables of these systems.

In general, it is difficult to directly study the robust stability of systems by parameters of the equations. Instead, we can estimate the output of the systems via the input and if the good input of a differential/difference equation implies the acceptable output then the system must be exponentially stable. That property is called Bohl-Perron Theorem.

This thesis presents the following contributions. First, it is identified that disturbance estimation based networks utilised for compensation possess the same polynomial architectures as signal conditioning anti-windup and their equivalents. Next, an appropriate strategy is identified to integrate disturbance compensation for finite-controlset optimisation schemes via the constraint set rather than the cost function to maintain a simple and elegant problem structure.

Phương pháp bình sai theo nguyên lý số bình phương nhỏ nhất chỉ phù hợp khi trị đo có chứa sai số ngẫu nhiên, tuy nhiên trong thực tế ngoài sai số ngẫu nhiên các trị đo còn chứa cả sai số thô. Hiện nay, một trong những phương pháp hiệu quả xử lý sai số thô là phương pháp ước lượng vững (Robust estimation).

We introduce the Microenvironment Cell Populations-counter (MCP-counter) method, which allows the robust quantification of the absolute abundance of eight immune and two stromal cell populations in heterogeneous tissues from transcriptomic data. We present in vitro mRNA mixture and ex vivo immunohistochemical data that quantitatively support the validity of our method’s estimates.

This paper concerns with a problem of supoptimal finite-time control for a class of linear large-scale delay systems. The system under consideration is subjected to the state and control delays interacted between subsystems. Based on improved LMI approach combining with new estimation techniques, we derive sufficient conditions for solving H∞ finite-time control and guaranteed cost control of the system. A numerical example is given to illustrate the validity and effectiveness of the theoretical results.

Genomic prediction (GP) is used in animal and plant breeding to help identify the best genotypes for selection. One of the most important measures of the effectiveness and reliability of GP in plant breeding is predictive accuracy. An accurate estimate of this measure is thus central to GP.

n this work, some popular analytic formulas such as Maxwell (MA), Mori-Tanaka approximation (MTA), and a recent method, named the Polarization approximation (PA) will be applied to estimate the elastic moduli for some porous media. These approximations are simple and robust but can be lack reliability in many cases. The Hashin-Shtrikman (H-S) bounds do not supply an exact value but a range that has been admitted by researchers in material science. Meanwhile, the effective properties by unit cell method using the finite element method (FEM) are considered accurate.

The paper deals with the robust state bounding estimation problem of stochastic control systems with discrete time Markovian jump. By using Lyapunov functional method and probability theory, we propose new sufficient conditions to guarantee robust state boundedness for the stochastic control systems. The conditions are derived in terms of linear matrix inequalities, which is simple and convenient for testing and application.
