Generating Electromagnetic Radiations

The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in...

Non-equilibrium in the Cell

5.7K
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Electric Generator: Alternator

3.7K
Electric generators induce an emf by rotating a coil in a magnetic field. A simple alternator is an AC generator that creates electrical energy that varies sinusoidally with time. A simple alternator consists of a conducting loop that is placed inside a uniform magnetic field. The loop is connected to split rings connected to the external circuit with the help of brushes.
The magnetic flux passing through the coil varies sinusoidally as the loop rotates inside the magnetic field. This...

Electrical engineering plays a pivotal role in our daily lives, with control systems at the heart of many applications, from home appliances to sophisticated space shuttles. Control systems manage and regulate the behavior of devices and processes, ensuring they function safely, correctly, and efficiently.
In modern vehicles, control systems manage various functions to enhance performance and safety. The steering wheel and accelerator are primary inputs in a car's control system. The...

Multi-input and Multi-variable systems

504
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence of...

    Area of Science:

    • Cognitive Psychology
    • Educational Psychology
    • Human-Computer Interaction

    Background:

    • Research in cognitive and educational psychology focuses on information learning and retrieval.
    • Alice Healy and colleagues have conducted extensive research on learning and memory.
    • Intelligent tutoring systems (ITS) aim to improve educational outcomes by incorporating learning principles.

    Purpose of the Study:

    • To discuss how three learning principles influence the design of two intelligent tutoring systems.
    • To describe the iSTART-2 and Writing Pal systems and their incorporation of skill and knowledge acquisition principles.
    • To argue for the value of integrating empirically supported learning principles into educational technology.

    Main Methods:

    • The study discusses the design of two intelligent tutoring systems: iSTART-2 and Writing Pal.
    • iSTART-2 trains students in comprehension strategies through self-explanation.
    • Writing Pal provides instruction and practice in writing strategies for persuasive essays.

    Main Results:

    • The design of iSTART-2 and Writing Pal is influenced by the generation effect, deliberate practice with feedback, and antidotes to disengagement.
    • These systems break down complex tasks into component skills and provide active generation with meaningful feedback.
    • Natural language processing techniques support the implementation of these principles despite the ill-defined nature of comprehension and writing.

    Conclusions:

    • Integrating empirically supported learning principles into educational activities is valuable, even with imperfect alignment.
    • Intelligent tutoring systems can be designed to leverage cognitive psychology principles for improved learning.
    • The described systems exemplify the practical application of learning science in educational technology.
