This paper is a contribution to the Floquet ideas applied for multitime overdetermined linear first order PDE dynamical systems with multi- periodic coefficients. The main results include: (1) a formula for the fundamental matrix; (2) the equivalence betw... see more

In this paper, we consider a numerical method for designing optimal controlon Linear Quadratic Regulator (LQR) problem. In the optimal control design process through Pontryagin Maximum Principle (PMP), we obtain a system of diferential equations in state ... see more

The existence of solutions of the Cauchy problem for (overdetermined) systems of linear partial differential operators with constant coefficients in some classes of functions or distributions is equivalent to the validity of Phragmen-Lindelöf-type princip... see more

Journalism practice in China is unique and different from the rest of the other countries in the world. Many scholars have attributed this to the effective regulatory systems and the structure of the media system thus the six forces controlling media spac... see more

This study aims to examine the effect of implementing regional financial regulations, employee competence and organizational commitment on the successful implementation of accrual-based accounting information systems and their impact on the quality of acc... see more

The digital economy has radically changed the way services and products are developed and deployed. Digital information and communication technology connects increasing numbers of people, organisations, and other systems. The interconnectedness of service... see more

The article, based on a literature review, examines the impact of electoral systems on the fluidity party system in sub-Saharan Africa. Most authors identify institutional and social factors influencing the change in party systems. At the same time, they ... see more

Discovery Unmanned Aerial Systems/UAS is used in various fields such as reconnaissance tools, topological mapping, and recreational purposes. This must be balanced with legal arrangements because there are many misuses of UAS operations. Act No. 1 of 2019... see more
