This article is devoted to the comparison of two object-relational mapping systems supported by .NET platform - Entity Framework Core and NHibernate. The research hypothesis “framework NHibernate is more efficient than Entity Framework Core in the context of DML operations” was put forward. In order to make an efficiency analysis of ORM frameworks, a desktop application was designed and implemented to enable testing and visualization of results. The NHibernate framework turned out to be much more efficient than Entity Framework Core in single tests and slightly faster in bulk tests. The stability of both frameworks was similar.

The research subject of this paper was the comparative analysis of efficiency of connections with databases using different communication methods based on Java programming language. The tools investigated included JDBC drivers and Object-relational mapping (ORM) frameworks. A survey based on 8 different criteria was conducted to determine the most effective method and tool for working with relational databases when developing Java applications. The weights of the criteria were determined through a survey of Java programmers and computer science students.

Translational Process

Abstract Our study presents a comparative analysis of selected texts from several translations of Queneau’s Exercices de style: the Romanian version (a collective work coordinated by Romulus Bucur), the English version (Barbara Wright) and the Italian one (Umberto Eco) that illustrate the variable degrees of difficulties in translating. The analysis is meant to confirm our research hypothesis: though disruptive and often hardly surmountable, translation constraint does not stifle translator’s creativity or his fidelity toward the original style; on the contrary, it stimulates the translational process and fosters the rewriting-creation.

Personnel management is a series of management activities for the company to select, use, train, evaluate, reward and punish its employees. The personnel management information system designed and implemented in this paper integrates the functions of batch import of information, instant update of personnel information, position transfer, information inquiry and statistical analysis. This system is oriented to various users such as managers at all levels of small and medium-sized enterprises and institutions. In this paper, using the aspect-oriented programming, Inversion of Control features of the Spring framework, using spring MVC model and using the ORM (Object Relational Mapping, Object Relational Mapping) feature of MyBatis, using B/S architecture and MySQL database, with high scalability, high refactorability as the design goal, designs and implements an Personnel Management Information System. The system builds a personnel database covering more than 20 information about personnel's basic information, education background, and positions, and realizes functions such as batch import of information, instant update of personnel information, job transfer, entry management, resignation management, information inquiry and statistical analysis. At the same time, it is ensured that these functions will not be illegally operated by users without authority, so that the system has higher security. This system provides an integrated solution for the informatization of personnel management and has high practical and commercial value.

Three Phase Inverter

The FOPID and PID controller are designed to control the speed of <br /> the BLDC motor. The parameters , , , λ and µ of these controller are optimized based on genetic algorithm. The optimized coefficients keep in track with zero error signals. The output of the controller is given to the variable dc source which varies the input voltage to the three phase inverter depending on the input signal. The three phase inverter gives the voltage to the BLDC motor which enhances the stability of the system. <br /> The effectiveness of the controller is demonstrated by simulation.
