Analysis of linear Phase-Locked Loops in Grid-Connected Power Converters Joachim Steinkohl, Xiongfei Wang, Pooya Davari and Frede Blaabjerg Aalborg University 

 Abstract

 Fast and accurate synchronization capability of grid-connected converters is becoming more and more important to ensure proper performance during transient events, such as grid faults. The higher requirements during the operation, as Fault-Ride-Through with reactive current injection, cause higher requirements on the operation during severe system conditions. This paper analyzes an addition to Synchronous-Reference-Frame Phase-Locked Loops for power electronic converters, that is linearizing the input signal. This enhances the tracking capabilities during abnormal transient events in the power grid. The improved control is analyzed and its increased performance is validated through simulations and experimental results.

Análisis Matemático En Preguntas by V.F. Butúzov; N.Ch. Krutitskaya; G.N. Medvédev; A.A. Shishkin

 

Análisis Matemático En Preguntas by V.F. Butúzov; N.Ch. Krutitskaya; G.N. Medvédev; A.A. Shishkin

 Este manual nace de la experiencia de años de enseñanza del análisis matemático en la Facultad de Física de la Universidad Estatal de Moscú. Está dirigido tanto a estudiantes como a profesores jóvenes que inician su labor docente, y cubre principalmente funciones de una variable, incluyendo medida e integral de Lebesgue. No se trata de una colección de problemas tradicional, sino de un material estructurado para favorecer una comprensión activa del contenido. Cada sección está organizada en cuatro partes: conceptos y teoremas fundamentales, preguntas de control, ejemplos resueltos y ejercicios para trabajo independiente. La sección teórica presenta nociones clave sin demostraciones, usualmente basadas en el manual de V. A. Ilin y E. G. Poznyak. Las preguntas de control ayudan al estudiante a verificar su comprensión. Los ejemplos explican cómo aplicar la teoría, destacando puntos críticos como condiciones de aplicabilidad. Finalmente, los ejercicios están cuidadosamente seleccionados por su variedad, y se complementan con respuestas e indicaciones. El objetivo general es facilitar tanto el aprendizaje autodirigido de los estudiantes como la enseñanza eficaz por parte del profesorado. Traducido del ruso por G. Lozhkin

 SOLUTION OF ELECTRICAL CIRCUITS IN ELECTRICAL ENGINEERING USING DEEPSEEK

APLICACION DEL DEEPSEEK COMO HERRAMIENTA DE APOYO EM LA RESOLUCION DE PROBLEMAS MATEMATICOS-APPLICATION OF DEEPSEEK AS A SUPPORT TOOL IN SOLVING MATHEMATICAL PROBLEMS

 

O DeepSeek pode ser aplicado em matemática de várias maneiras, como na resolução de problemas matemáticos, entendimento de linguagem natural e raciocínio passo a passo. Ele é usado para abordar tarefas científicas em áreas que incluem matemática e raciocínio cognitivo. Pesquisadores têm testado a eficácia do modelo em tarefas específicas, explorando sua capacidade de lidar com conceitos matemáticos complexos, como a irracionalidade de π ou a impossibilidade de trisecar um ângulo com régua e compasso. É recomendável verificar informações importantes para garantir precisão. Embora DeepSeek seja uma ferramenta poderosa, é essencial entender suas limitações. Para problemas matemáticos complexos, pode ser necessário o envolvimento humano para verificar, avaliar e interpretar as soluções propostas pela IA.

Quantum physics of solids-Квантовая физика твердого тела-Authors: S.V. Vonsovsky, M.I. Katsnelson

 Quantum physics of solids-Квантовая физика твердого тела-Authors: S.V. Vonsovsky, M.I. Katsnelson Authors: S.V. Vonsovsky, M.I. Katsnelson

 Information about the publisher: Moscow: Chief editorial board of physical and mathematical literature of the Nauka publishing house, 1983. – 336 p., In addition to the traditional material devoted to quantum solid-state physics, the book covers such issues as neutron scattering, the Mössbauer effect, metal-insulator transitions, plasma phenomena and other multielectron effects, and pseudopotential. Particular attention is paid to general issues of solid-state theory (the Schrödinger equation with a periodic potential, the self-consistent field approximation, the limits of applicability of band theory, and a number of others). The presentation assumes knowledge of only the basics of quantum and statistical mechanics and does not use complex mathematical apparatus.

Limits And Continuity ( Pocket Mathematical Library) by P. P. Korovkin

 

Limits And Continuity ( Pocket Mathematical Library) by P. P. Korovkin

The present volume in The Pocket Mathematical Library stems in large part from Chapters 1-4 of P. P. Korovkin’s Mathema­tical Analysis, Moscow (1963). The material has been heavily rewritten and supplemented by 21 problem sets, one after each section. The result is a succinct but remarkably complete introduction to the theory o f limits and continuity. The book may also be thought of as a “precalculus” text in that it deals with those properties of functions which can be successfully discussed short of introducing the notion of a derivative.

COLLECTION OF OLYMPIAD PROBLEMS IN HIGHER MATHEMATICS-V. M. Shakhmatov, A. L. Lisok,T. C. Tarbokova-Publishing houseTomsk Polytechnic University-2010

 

Collection of Olympiad problems in higher mathematics: textbook / V. M. Shakhmatov, A. L. Lisok, T. V. Tarbokova - Tomsk: Publishing HouseTomsk Polytechnic University, 2009. – 144 p

.The basis of the textbook is problems (there are more than eight hundred of them) - from all sections of mathematics, offered to first- and senior-year students at intra-university (TPU, TSPU), regional (Tomsk) and regional and all-Russian rounds of the Olympiad in mathematics, as a subject and as a specialty over the past ten to fifteen years. In addition to problems for independent solution, the collection includes more than fifty problems with solutions or instructions. This manual can be recommended for students to prepare for mathematical Olympiads; teachers - to work with students as part of extracurricular activities. Some problems can be offered as individual tasks in mathematics, and can also be useful when writing essays.
