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 voltage ...

I need a compact acquisition board that reads pressure sensors and sends data by Bluetooth and Celullar (SIM). Your job covers both the hardware and the embedded layer that will live on the board. System Requirements : A custom PCB (embedded system) must be designed to interface with the sensor.

The PCB will receive pressure data from the sensor through front-end components directly connected to the electrode outputs. A microcontroller (MCU) will scan the matrix at high frequency by sequentially energizing one electrode (e.g., rows) and measuring responses across perpendicular electrodes (e.g., columns). This scanning process allows detection of pressure points acros...

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 prod...

I’m an Electrical Engineering student and I sometimes need an extra set of expert eyes on my coursework. When a problem set, small project, or concept gives me trouble I’ll send you the questions or brief and expect a clear, step-by-step solution that also teaches me the underlying reasoning. Most tasks revolve around mainstream Electrical Engineering subjects—think circuit analysis, power calculations, or introductory control principles—so a broad foundation is essential, even if we end up focusing on just one of those areas at a time. Deliverables for each request • A worked solution in Word / PDF with every step shown • A concise explanation of the theory or method used • (When relevant) simulation or code files from MATLAB, Multisim, PSpice, ...

I need a seasoned Radio Access Network expert to stress-test the solution my team is building in three key areas. First, you will comb through 35–45 existing datasets and feature columns drawn from 4G/5G CM, PM, KPI and call-trace sources. Your job is to confirm each field’s value for fault detection, highlight any RAN counters or critical signals we have missed, and flag redundant noise we can drop. Next, you will review the correlation logic that powers our automated root-cause analysis. I will share flow-charts, rule sets and a Bytelens sandbox. I want to know whether the way we link alarms, counters, interference metrics and topology really mirrors what happens on a live network and matches common troubleshooting practice in the field. Finally, you will turn the insights...

I need production-ready firmware for an STM32F303 that turns the microcontroller into a front-end for high-speed digitisation of SDR signals. The chip’s ADCs must sample the incoming RF-baseband stream, move the data through DMA with minimal latency, and prepare it for onward transmission over a fast serial link (either SPI or UART—whichever achieves the cleanest, sustained throughput on this part). The core of the job is sensor-style data processing: capture, buffer, and pre-format the raw samples so that an external host can handle the heavier DSP. No motor-control, no classic temperature or pressure sensors—just clean, reliable handling of SDR-grade analogue input. Key expectations • Continuous, gap-free acquisition at the highest practical sampling rate for t...

I need a compact, low-power PCB engineered for a wearable that can both record video and react to motion events. The board must support a micro camera module, motion sensor (IMU or PIR, whichever fits best), local storage and a simple interface for later firmware integration.

Hi I will share the details with the shortlisted candidates. thanks

I have an ESP32 Basic Core IoT Development Kit V2.7 installed in my truck and need firmware that will warn me whenever the Starlink router stays powered after I switch the ignition off. The sketch should watch a dedicated ignition-sense pin: while the line is high the unit does nothing special, but as soon as it goes low it must keep polling the Wi-Fi connection status in code. If the ESP32 is still associated with any network after a user configurable amount of time, an on-board LED must begin to flash, screen starts flashing and the internal speaker must chirp in tandem until the Wi-Fi link drops or the ignition is restored. I would like a simple LCD screen interface on the kit’s I²C display that shows real-time states (“Ignition ON / OFF”, “Wi-Fi CONNECT...
