I want to decide on the most appropriate semiconductor switch for a new switch-mode power supply design, with switching speed as the overriding priority. Although I initially considered a thyristor, I’m open to any device—MOSFET, IGBT, BJT or another alternative—that demonstrably outperforms the rest once the figures are on the table. Here’s what the work entails. First, analyse the SMPS topology and its expected operating conditions, then shortlist realistic candidates and justify the final choice in terms of rise/fall times, turn-on/turn-off losses, and any ancillary gate-drive or snubber requirements. Once the device is chosen, run a full simulation (LTspice, PSpice, SIMetrix, MATLAB Simulink or equivalent) that shows switching waveforms, efficiency trends over ...

Key Requirements: - Use ANSYS for FEA - Compare Eurocode and FEA results - Focus on thermal response of beams - Technical report documenting findings Ideal Skills: - Proficiency in ANSYS - Strong understanding of steel fire design and Eurocode - Experience with thermal response analysis

I have an existing component that will be produced by die casting, and I need a seasoned engineer to take it from a “good-enough” 3D file to a production-ready design. Your first task is to prepare and clean the current CAD geometry in AutoCAD, eliminating any issues that could complicate the tooling or filling stages. From there, I want you to run a full die-casting simulation—filling, solidification, and thermal cycles—to expose hot spots, air entrapment, or misruns. The ultimate goal is to enhance manufacturability, so every change you propose should shorten cycle time, reduce scrap, or simplify the mold. Thin-wall tweaks, draft adjustments, gating and overflow suggestions, or rib relocations are all on the table as long as they keep the part’s function...

The objective is to create a scalable simulation framework that combines: •⁠ ⁠Electronics & Communication Engineering (EC) •⁠ ⁠Mechanical Engineering •⁠ ⁠Artificial Intelligence / Machine Learning •⁠ ⁠Computer Science •⁠ ⁠Information Science •⁠ ⁠Robotics and Automation •⁠ ⁠IoT Systems •⁠ ⁠Digital Twin Concepts The preferred technology stack is MATLAB and Simulink due to their ability to model, simulate, and integrate hardware, software, c...

I have an electric-field simulation set up in Ansys Maxwell, yet the field distribution patterns I obtain look nothing like the physical behaviour I expect. Geometry, material assignments, excitations and solver settings all appear reasonable, but every sweep still produces the same unexpected plots. I’d like a fresh pair of expert eyes to: • Review my project file step-by-step – geometry, boundary conditions, excitations, mesh and solver setup. • Identify why the results diverge from theory and provide the specific parameter tweaks or modelling changes that will bring the field plots back in line. • Guide me explaining the root cause and documents the corrections so I can reproduce the fix on future designs. Remote session access to my workstation is...

I already have my geometry ready and I now need it set up, meshed, and solved entirely in either PrePoMax or Mecway—whichever you are most comfortable with. Once you receive the model, please build the analysis from start to finish: define the contacts, choose appropriate element types, apply realistic loads and boundary conditions, and run the solver until stable, converged results are obtained. I will share further details about the operating environment, objectives, and any material data once we start so you can tailor the setup accordingly. What matters to me is that the project file can be opened and rerun on my side without modification, and that I receive a concise report summarising assumptions, key plots, and numerical results. Deliverables: • Native PrePoMax or Mec...

I have a complete 3-D STEP model of a cell that houses four FANUC robots. What I now need is the full offline programming that makes each robot carry out a simple, repeatable welding and assembly cycle, then a video that captures those motions in a clean loop. Scope • Import the STEP model into Roboguide or any comparable FANUC-compatible offline environment. • Create the programs from scratch: two robots weld, two handle the required assembly moves. • Keep the sequence straightforward—no fancy camera fly-throughs or environment physics—just clear, collision-free motions that show the basic task execution from a fixed or gently panning viewpoint. Deliverables 1. A short MP4 (around one-two minute) that plays the full cycle on repeat. Acceptance ...

I need an analog circuit designed from the ground up and then laid out on a production-ready PCB for a consumer-electronics product. The finished board must operate as a single, unified control unit that fits cleanly inside a dedicated enclosure, so component placement and overall footprint matter as much as the schematic itself. I need an integrated control panel which houses two subsystems. One is water pumping line and the second is uv disinfection line. The circuit diagram for both subsystems will be provided . Kindly provide an integrated one and a pcb design for the same.

I am looking for LTSpice expert who can deliver simulation result per project. It is not one time project and if you are good candidate, we can cooperate for a long time. Also, we have to work on slack. Budget: 20$/task, 2 tasks/every day. Please share your LTSpice experience.

I need help turning our data-centre concept into a fully functioning Bentley iTwin digital twin, with an emphasis on simulation and modelling. The goal is to capture the entire life-cycle—from chip placement right through to deployment and ongoing operations—and then run detailed environmental simulations on that virtual model. Here’s what I expect: • A clean iTwin setup that accurately mirrors our proposed data-centre layout, equipment stacks, power and cooling paths. • Environmental simulation scenarios that let us test heat distribution, airflow, energy consumption and failure contingencies before we build anything in the real world. • Clear, repeatable workflows so my internal team can update the model as designs evolve. • A concise report ...

# VR Application for English Communication Training (Meta Quest 3) ## Project Overview I am looking for a Unity VR developer to create a simple and expandable VR application for Meta Quest 3. The goal of the application is to help users practice spoken English and social interaction in realistic international environments. The application will be used in instructor-led communication training courses. The VR environment provides immersion and social presence, while the instructor guides the conversation in real life. This is an educational project, not a game. ## First Environment: International Student Residence Kitchen The first environment should simulate a shared student residence kitchen. The participant starts seated at a round table. Three to five international students (NPCs...

The way production orders are sequenced and scheduled has a significant effect on: Throughput Machine utilization Lead times Overall efficiency Objective The main goal is to: Measure and compare how different scheduling algorithms affect production performance. Rather than just applying scheduling methods, the thesis aims to quantify their impact using measurable performance indicators. Approach The work is based on simulation using Siemens Plant Simulation, where a virtual factory model is created. The process: Model a production system Multiple mach...

I am building a complete 2-D/3-D study of multi-gate Tunnel FETs and need a Silvaco TCAD specialist who can move smoothly from process/device simulation to compact modeling and, finally, circuit-level validation. The work starts with setting up accurate Silvaco decks that replicate published or measured baselines, then extracting an analytical model that captures I-V behaviour, threshold voltage, sub-threshold swing, switching time and leakage current with good fidelity. Once the reference is solid, we will begin gate engineering: swapping in High-k dielectrics, Metal gates, Poly-silicon gates and exploratory stacks such as InGaAr and GaAr, quantifying the impact of each on the same figures of merit. When a promising configuration emerges, I need the model parameterised so that it can be...
