...stiffness and damping when the foundation is subjected to harmonic loading and to understand how those properties change with excitation frequency, soil shear modulus, and pile length. Please build non-linear soil–pile interaction models, run frequency-domain analyses, and extract the complex impedance functions across the required frequency range. After the runs, post-process the results in MATLAB, Excel, or Python so I can clearly see: • dynamic stiffness versus frequency • dynamic damping versus frequency • side-by-side parametric comparisons for the three varied parameters (soil shear modulus, pile length, excitation frequency). Deliverables that will allow me to reproduce and publish the study: 1. Fully documented ABAQUS model files for th...
Project Goal We are looking for an experienced FPGA/SoC engineer to guide and mentor a university-level engineering project focused on developing a reusable SoC/FPGA validation framework for controller IP cores generated from MATLAB/Simulink using HDL Workflow Advisor. The initial case study is a PID controller implemented on a Xilinx SoC FPGA platform using MATLAB/Simulink, HDL Coder, and Vivado. Scope of Work The freelancer will guide the student in: • Designing and validating controller algorithms in MATLAB/Simulink • Generating HDL and packaging custom IP cores using HDL Workflow Advisor • Creating a custom Vivado reference design instead of using the default HDL Workflow Advisor design • Integrating the controller IP with: * Zynq Processi...
I need a detailed MATLAB/Simulink model that shows how a Level 3 DC fast-charging station behaves when a passenger-car battery is pushed for maximum charging speed, and how that strategy ripples back through the local grid. The core goal is charging-speed optimisation: I want to see, step by step, how tweaks to current limits, power-electronics control, and battery thermal constraints shorten overall charge time without forcing the feeder or transformer outside safe operating limits. Scope of work • Build or adapt a modular Simulink/Simscape Electrical model of a 350 kW DC fast charger, its power-conversion stages, and a representative passenger-car battery pack. • Integrate a simplified distribution-grid section (utility connection, line impedance, transformer) s...
I need a MATLAB/Simulink implementation of a 9-level cascaded H-bridge inverter that uses Selective Harmonic Elimination (SHE) to drive total harmonic distortion as low as possible. The simulation must show, through FFT analysis inside Simulink, that the output voltage meets a THD target that clearly improves on a conventional carrier-based PWM approach. My priority is minimising THD, and I also want to see concrete steps that reduce power losses, especially those linked to the switching devices. Please choose switching angles that strike the right compromise between harmonic suppression and conduction losses; I am not currently concerned with the transformer or passive elements. Deliverables • A clean, well-annotated Simulink model that produces a nine-level line-to-line v...
...improve—the accuracy of heart-rate, blood-pressure, respiratory-rate and broader adherence-related metrics. You would help me design the study protocol, define gold-standard comparisons, supervise data collection, and iterate on the signal-processing / machine-learning code that powers our on-device analytics. A solid grasp of biostatistics, clinical research methods, and coding in Python, R or MATLAB will be essential, and familiarity with FDA or CE guidance for digital health products is a plus. Deliverables I need from you: • A clear validation plan ready for IRB submission • Statistical analysis scripts and clean datasets • A concise report highlighting accuracy, error sources, and practical algorithm improvements If you have run similar tr...
... Because the work is ongoing, I’m looking to partner with a single Indian writer who can handle every stage—from literature review to final formatting—without leaning on an agency team or agency-level pricing. The core of the job is research-paper writing, but many projects also require numerical analysis and simulation work. You should therefore be comfortable jumping between Python scripts, MATLAB models, and the usual suite of engineering tools when the study calls for it. If you already integrate both platforms into your workflow, you will fit in perfectly. Quality is non-negotiable: every draft must return a combined plagiarism and AI-generated content score below 10 %. Strong citation management, adherence to target-journal templates, and clear, concise ...
...amplitude: F₀ = 150 N * Excitation frequencies: * f₁ = 3.5 Hz, so Ω₁ = 21.991 rad/s * f₂ = 14 Hz, so Ω₂ = 87.965 rad/s The motion of the machine is governed by the equation: mddot{x}(t) + c_edot{x}(t) + k_e x(t) = F_0 sin(Omega t) where x(t) is the vertical displacement response of the machine. Required Work 1. Develop a MATLAB Model Create a MATLAB script that solves the equation of motion using a suitable ODE solver, such as ode45. The MATLAB model should include: * Definition of system parameters: mass, damping, stiffness, force amplitude, and excitation frequency. * Conversion of the second-order differential equation into first-order equations. * An m-function to represent the equation of motion. * Simulation of the system respon...

I need a fully-functional Smart Calculator written in MATLAB that runs indefinitely inside a single while loop and presents its options through a switch-driven main menu. Every mathematical routine must live in its own user-defined function; no direct use of max(), min(), sum() or similar helpers. Core features to code • Matrix tools: Inverse, Transpose and Multiplication for any conformable matrices the user enters. • Vector tools: Find Max, Find Min and Calculate Sum, each obtained through your own loop-based logic. • Number analysis: Even/Odd detector (simple modulo logic is fine). • General arithmetic and a small trigonometric block (sin, cos, tan may rely on MATLAB’s built-ins). Keep the structure clean: one master script shows the menu, ca...
I have a MATLAB assignment centred on building a clean, well-documented simulation that works with purely numerical data and leverages the Curve Fitting Toolbox for analysis. The task is concept-driven rather than template-based, so every line of code must be original and fully plagiarism-free. You will start from a short problem statement and raw data I supply, develop the simulation logic, apply appropriate curve-fitting routines, and return results that are easy for me to reproduce. Efficiency and clear commenting are critical, as I’ll be stepping through each function myself. Deliverables • One or more .m files containing the complete, self-contained simulation • Brief README or inline comments explaining setup, assumptions, and how to run the script Acc...
I need a complete procedure for importing a text file into MATLAB. The file contains a time series of stock trades with OHLC data and several indicators. Requirements: - Procedure to import a txt file - Data columns are labeled in the first row - Data includes: - Open, High, Low, Close (OHLC) - Moving Average (MA) - Relative Strength Index (RSI) - Bollinger Bands (BB) - Other proprietary indicators - Develop a buy/sell formula based on thresholds
...precision-grade stimulator project that requires deep knowledge of constant-current sources and patient safety. Project Scope & Deliverables: Full Hardware Design: Schematic, PCB Layout (low-noise), and organized BOM. Firmware Development: Embedded C/C++ code for waveform generation, timing, and UI control. 100% Verified Simulation: You must demonstrate that the circuit works perfectly in simulation (SPICE, MATLAB, or similar) before finalizing the layout. Production-Ready Quality: The final PCB must be optimized to ensure zero issues with EMI, noise, or signal interference when manufactured. Technical Requirements: Experience with Biphasic Constant Current Drivers (0-25mA). High compliance voltage management (up to 85V). Knowledge of charge-balanced waveforms to prevent tiss...
I need to reproduce the complete control model from a published paper on grid-connected photovoltaic inverters—specifically the PI + Resonant current controller—and then push the work further by adding an intelligent ANN-based control structure. Everything must be built and run in MATLAB/Simulink so that I can validate the original results first, then make a clear side-by-side comparison between the classical and the new approach. The task starts with an exact replication of the paper: identical parameters, same test grid, and matching waveform plots. Once that baseline is confirmed, you will design, train, and integrate an artificial neural network controller, tune it, and show how it behaves under identical scenarios. I am especially interested in response time, harmo...

Long-term collaboration is possible for the right candidate....
I need a runnable MATLAB/Simulink file that captures the core behaviour of a Push-Pull DC-DC converter. My focus is on simulation practice rather than deep physical accuracy, so a basic functional representation of the key power-stage elements will do the job. Scope • Model only the transformer, switching devices (two MOSFETs), diodes plus R(load) and L & C filter. • Keep the level of detail functional—no temperature coefficients or parasitic extraction is required. • Allow input voltage, duty cycle, and transformer turns ratio to be parameterized so I can experiment quickly during lab sessions. • Provide simple scopes so I can observe primary currents, secondary voltage, and the switching node waveform. Deliverables 1. .slx file with clear, ...
...developing and analysing a complete MATLAB/Simulink model that starts with a single DC motor and scales up to a gravity-affected multi-link robotic arm. The aim is to follow an Independent Joint Control strategy, prove closed-loop stability and meet performance targets before I finalise my report. The work begins with a pure Simulink build of the motor using gains and integrators, followed by open- and closed-loop simulations of position and velocity. We will introduce an amplifier gain, inject representative disturbances, and study how the motor behaves. From there I want the closed-loop transfer functions written out, then a PI controller designed with the root-locus method. Settling-time, overshoot and steady-state error all have to be verified in MATLAB to confirm the...
I’m looking for an agile researcher who can jump between Machine Learning, Deep Learning, Computer Vision and core Electrical Engineering work without missing a beat. Most of what I send your way will sit at the intersection of data-driven algorithms and classic engineering analysis: think rapid literature scans, model prototyping in Python (TensorFlow / PyTorch), quick-turn MATLAB or Simulink simulations, and concise technical write-ups that translate results into clear engineering insights. The project stream is firmly rooted in Electrical Engineering, so an ability to frame ML findings in terms of circuits, signal behaviour, power-system performance or similar contexts is essential. Speed matters—I often need same-day clarifications or iterative tweaks—yet I ne...

...masterpiece—something that runs, produces clear plots and lets me tweak geometry or spring rates and immediately see the kinematic effects. Core behaviours to evaluate are anti-dive angles, anti-squat angles and spring stiffness influence. Steering analysis would be a bonus if it can be added without blowing up the scope; I’m happy either way. I picture you importing or rebuilding the geometry inside MATLAB/Simulink, setting up proper joint definitions and reference frames, and giving me a clean parameter set so I can dial in numbers for ride height changes, anti-geometry percentages, etc. Please deliver the finished Simulink file (2024b preferred), brief notes on how to edit key parameters, and a few example plots—wheel travel, roll centre shifts, wishbone mo...
I need a full MATLAB/Simulink model of a single-phase, grid-connected photovoltaic system that lets me plug in my own DC-DC boost converter topology and then closes the loop with a Proximal Policy Optimization (PPO) controller. The priority is clear: the reinforcement-learning algorithm must deliver high accuracy in tracking the reference—voltage, current, or power—throughout irradiance and load changes. Here is what I expect: • A modular Simulink file where the PV array, my custom boost converter, the single-phase inverter, the LCL or LC filter, and the grid interface are clearly separated so I can swap devices in or out. • A PPO training script (MATLAB RL Toolbox or compatible Python interface) that learns directly on the Simulink environment and...
...I want the complete behaviour of the robot reproduced in both MATLAB scripts and a Simulink model so that I can run rapid what-if studies, tune controllers, and visualise trajectories with confidence. Your focus will be to refine any missing dynamics, implement the full nonlinear model, and build a clean, well-documented Simulink environment that mirrors the MATLAB code line-for-line. Once the model is stable, I will also need repeatable simulation scenarios (step, sinusoidal, and user-defined joint inputs) together with meaningful plots—joint positions, velocities, torque profiles, and energy consumption. To be considered, include a concise yet detailed project proposal that tells me • how you intend to structure the MATLAB functions and Simulink blo...

I need help with the following: • Creating professional graphs from my data (frequency vs effective height, comparison plots) • Designing clear engineering figures (beam cross-section, concept illustration of stiffness degradation) • Improving tables and visual presentation • Formatting the paper according to journal template (spacing, captions, layout) Tools preferred: MATLAB / Python / Excel for graphs, and professional figure tools (AutoCAD, Illustrator, or similar) Ideal candidate: • Background in civil/structural/mechanical engineering • Experience with academic journal papers • Strong visualization and technical formatting skills Deliverables: • High-quality figures (publication-ready) • Clean formatted...
I need a clear, well-documented MATLAB model of an electrical circuit built around inductors and a transformer so I can study its steady-state and transient performance. The focus is on performance analysis rather than behavioural quirks or failure modes, so accurate numerical results, efficiency figures and waveform plots matter more than visual presentation. The circuit topology and parameters will be supplied as soon as the project starts; you will translate them into either a pure-MATLAB script or a Simulink file (your choice, as long as it runs in current MATLAB releases without extra toolboxes beyond Simscape Electrical). Please make sure your model captures magnetic coupling, core losses (if practical) and any parasitic elements needed for realistic results. D...
