This Week's Proposals
14 proposalsThermodynamic Cycle Comparison: Otto vs Diesel vs Rankine
Compare efficiency of different thermodynamic cycles side-by-side. Adjust compression ratios, heat input, and working fluid properties. Visualizes P-V and T-S diagrams with real-time efficiency calculations for each cycle.
Buffer Solution pH Calculator and Titration Curve
Interactive tool for calculating buffer pH using Henderson-Hasselbalch equation. Users can adjust pKa, concentration ratio, and acid concentration to see pH changes. Generates titration curves for strong acid-weak base and weak acid-strong base titrations with real-time calculations.
Neural Network Training Visualizer
Watch a simple neural network learn in real-time. Users can configure network architecture, select datasets (circles, moons, or custom), adjust learning rate and regularization. Visualizes decision boundaries and loss curve as network trains.
AC Circuit Impedance and Phase Angle Calculator
Interactive AC circuit analyzer for series and parallel RLC circuits. Calculate impedance, resonant frequency, quality factor, and phase angle. Visualize phasor diagrams and frequency response curves with adjustable component values.
Spring-Mass-Damper System Interactive Simulator
An interactive visualization for exploring how damping affects oscillatory motion. Users can adjust spring constant, mass, damping coefficient, and initial conditions to see real-time effects on displacement, velocity, and energy. Includes preset configurations for underdamped, critically damped, and overdamped systems.
Fourier Transform Frequency Domain Visualizer
Visualize how the Fourier Transform converts time-domain signals to frequency domain. Users can draw or select predefined waveforms (sine, square, sawtooth) and see their frequency spectrum in real-time. Includes filtering, window functions, and zooming capabilities.
Power Factor Correction and Reactive Power in AC Systems
Interactive tool for understanding reactive power and power factor correction. Calculate capacitor values needed to correct power factor, visualize power triangle, and see energy savings from correction. Includes industrial case studies.
Binary Search Tree Visualization and Operations
Step-through visualization of binary search tree operations: insertion, deletion, search, and traversal (in-order, pre-order, post-order). Shows tree rebalancing for AVL trees. Educational tool for understanding tree structures and complexity.
Real-Time Signal Processing Workbench
Build and test digital signal processing chains in real-time. Includes common DSP blocks: filters (FIR, IIR), FFT, convolution, and modulation. Visualize frequency response and spectrograms with audio input support.
Laplace Transform Solver and Differential Equation Solution
Step-by-step solver for using Laplace transforms to solve differential equations. Input a linear ODE, the tool shows Laplace transformation, algebraic manipulation, and inverse transform to get the time-domain solution. Includes common transform pairs reference.
Enzyme Kinetics and Michaelis-Menten Interactive Model
Explore enzyme kinetics with adjustable Vmax and Km parameters. Visualize substrate concentration effects on reaction rate, including inhibitor effects (competitive, non-competitive). Includes Lineweaver-Burk plot and initial velocity data generation.
Computational Fluid Dynamics: Navier-Stokes Flow Solver
Simplified 2D incompressible flow solver using finite difference method. Users define boundary conditions, obstacles, and velocity profiles, then watch fluid flow patterns evolve. Includes streamline visualization and pressure field heatmaps.
Genetic Drift and Population Genetics Simulator
Monte Carlo simulation of genetic drift in finite populations. Users set initial allele frequencies and population size, then watch how allele frequencies change randomly over generations. Includes comparison with Hardy-Weinberg equilibrium.
Crack Propagation and Fracture Mechanics Simulator
Visualize stress concentration around cracks and predict failure using fracture mechanics principles. Adjust crack length, loading, and material properties to calculate stress intensity factor (KI) and predict crack growth rate.
