The document discusses cinematica (kinematics) in normal and tangential coordinates. It specifically analyzes intrinsic acceleration components, which are the decomposition of the acceleration vector along intrinsic axes. The tangential component is responsible for changes in velocity magnitude, while the normal component is zero for rectilinear motion. Measurement data is presented to calculate errors for analyzing motion along a curved trajectory using normal and tangential coordinate systems. Conclusions discuss considering all variables for calculations and understanding the reference system of the model.

Output feedback trajectory stabilization of the uncertainty DC servomechanism...ISA Interchange
This work proposes a solution for the output feedback trajectory-tracking problem in the case of an uncertain DC servomechanism system. The system consists of a pendulum actuated by a DC motor and subject to a time-varying bounded disturbance. The control law consists of a Proportional Derivative controller and an uncertain estimator that allows compensating the effects of the unknown bounded perturbation. Because the motor velocity state is not available from measurements, a second-order sliding-mode observer permits the estimation of this variable in finite time. This last feature allows applying the Separation Principle. The convergence analysis is carried out by means of the Lyapunov method. Results obtained from numerical simulations and experiments in a laboratory prototype show the performance of the closed loop system.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Carrera: Ingeniería Electromecánica
Física 1
Tema: CINEMATICA EN COORDENADAS
NORMALES Y TANGENCIALES
Docente: Ing. Proaño Molina Diego Orlando
2021-2022
2. Objetivo General:
Validar la ley física y análisis de un sistema de dinámica en
coordenadas normales y tangenciales
Objetivos Específicos:
Investigar y diseñar un modelo de acuerdo a nuestro tema
tratado en coordenadas normales y tangenciales.
Construir la maqueta y tomar en cuenta las dimensiones de
la misma, para así poder llevar a cabo el cálculo de errores.
Determinar el instrumento de medición más adecuado para
nuestra práctica.
Analizar las componentes en coordenadas normales y
tangenciales.
3. CINEMATICA
La cinemática es la parte de la mecánica clásica que estudia la
descripción del movimiento de un cuerpo, sin atender a la causa
que lo produce. Se limita esencialmente al cálculo de la
trayectoria del cuerpo en función del tiempo. Para ello se debe
utilizar un sistema de coordenadas, llamado sistema de
referencia, constituido por tres ejes perpendiculares entre sí
(ejes XYZ).[1]
4. COMPONENTES INTRÍNSECAS
Se definen las componentes intrínsecas de la aceleración como
la descomposición del vector aceleración en los ejes intrínsecos.
A la componente que se proyecta sobre el eje tangente se le
llama componente tangencial y es la responsable del cambio del
módulo de la velocidad. En algunas ocasiones conviene usar un
sistema de referencia cuyos ejes sean en cada instante tangente
y normal a la trayectoria no son fijos [2].
5. Aceleración tangencial. _ nula cuando el módulo de la
velocidad es constante.
Aceleración normal. _nula cuando el movimiento es rectilíneo
6. MOVIMIENTO CURVILINEO
El movimiento curvilíneo ocurre cuando la partícula se mueve a
lo largo de una trayectoria curva. Como esta trayectoria a
menudo es descrita en tres dimensiones. usaremos análisis
vectorial para formular la posición, la velocidad y la aceleración
de la partícula: En esta sección se analizan los aspectos
generales del movimiento curvilíneo. y en secciones
subsecuentes se presentarán tres tipos de sistemas coordenados
usados a menudo para analizar este movimiento.[6]
