A brief and easy concept of Simple harmonic oscillator. How we can get simple harmonic motion equation from Lagrange's equation of motion. How can we obtain this from Lagrange's equation of motion.
Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis, fulcrum or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist. In an electrical sense, torque makes the coil in a DC motor rotate due to the application of a force via the motor effect.

In this book, we look at the analytical integral approach used to solve the heat equation. We look at different cases of boundary and initial conditions and we solve the heat equation using exponential temperature profiles that satisfy the boundary and initial conditions. We go ahead to look at predictions made by the solutions we have calculated and verify them experimentally. We look at different geometries including rectangular coordinates, cylindrical cordinates and solve their governing equations analytically. We look at the predictions of the transient state made by the solutions and verify them experimentally. We look at scenarios of semi-infinite rods, finite rods including semi-infinite cylinders and finite radius cylinders. We go ahead to develop the governing equation for heat loss by convection for a liquid in a container.In all the above solutions, we used the integral approach to solve for the solutions. We compare the Fourier series solution to our solution and we realise that the Fourier solution is approximate since it involves summing terms to infinity yet we notice that our solution is exact. We look at cases where theres is both conduction and natural convection at the sides of the rod and solve the governing equations for given boundary and initial conditions. We realise that our method of approach can be used to solve the heat equation for any type of boundary conditions.

RADIAL HEAT CONDUCTION SOLVED USING THE INTEGRAL EQUATION .pdfWasswaderrick3
Β
We look at the case of radial heat flow. Again, in radial heat flow, the temperature profiles that satisfy the boundary and initial conditions are the exponential and hyperbolic functions as derived in literature of conduction in fins. We use the technique of transforming the PDE into an integral equation. But in the case of radial heat flow, we have to multiply through by r the heat equation and then introduce integrals. We do this to avoid introducing integrals of the form of the exponential integral whose solutions cannot be expressed in the form of a simple mathematical function. We look at the case of a semi-infinite hollow cylinder for both insulated and non-insulated cases and then find the solution. We also look at cases of finite radius hollow cylinders subject to given boundary conditions. We notice that the solutions got for finite radius hollow cylinders do not reduce to those of semi-infinite hollow cylinders. We conclude by saying that this same analysis can be extended to spherical co-ordinates heat conduction.

Mathematical analysis of non-uniform polyhedra having 2 congruent regular n-g...Harish Chandra Rajpoot
Β
All the important formulas have been generalized which are applicable to calculate the important parameters, of any non-uniform polyhedron having 2 congruent regular n-gonal faces, 2n congruent trapezoidal faces each with three equal sides, 5n edges & 3n vertices lying on a spherical surface, such as solid angle subtended by each face at the centre, normal distance of each face from the centre, inner radius, outer radius, mean radius, surface area & volume. These are useful for the analysis, designing & modeling of different non-uniform polyhedra.
The mathematics of vectors is quite different from the mathematics of scalar quantities. For Example, in the multiplication of scalar quantities we use the βdot productβ, whereas in the multiplication of vector quantities we use the βcross productβ or the vector product method to account for direction.

TRANSIENT AND STEADY STATE HEAT CONDUCTION WITH NO LATERAL CONVECTION SOLVED ...Wasswaderrick3
Β
In this book we go ahead and solve for the transient and steady state heat conduction phenomena in one dimensional heat flow with no lateral convection. It is known that there exist a Fourier series method but the problem of this method is that it is an approximate method since it involves summing up to infinite number of terms which we can never achieve in practice without approximating. In this book we develop an analytic solution to the heat equation with no lateral convection by using the already derived hyperbolic temperature profile functions in literature and solve the heat equation using these functions and the integral equation method and get a solution of the time dependent parameter Ξ΄ which we substitute in the temperature profile. We deal with different types of boundary conditions and get their solutions. In solving for the steady state temperatures, we use the Lβhopitalβs rule since we get undefined limits when we substitute for time tending to infinity in some cases. We realize that the steady state temperature profile agrees with theory.
SEMI-INFINITE ROD SOLUTION FOR TRANSIENT AND STEADY STATE.pdfWasswaderrick3
Β
For the case of conduction of semi-infinite metal rod in natural convection, we postulate that the temperature profile which satisfies the boundary conditions and the initial condition is the exponential temperature profile. We go ahead and solve the heat equation using this temperature profile and the integral approach and the solution got is used to explain what is observed in the transient and steady state. We notice that the prediction made by the theory is not exactly what is observed with an intercept term which comes in. To account for this intercept, we postulate that thereβs convection at the hot end. This accounts for the observed intercept. This analysis can be extended to metal rods of finite length with given boundary conditions and different geometries.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Β
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 wasnβt 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.
Embracing GenAI - A Strategic ImperativePeter Windle
Β
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
