Simulate pathogen tracking using DPM or species transport to calculate cumulative UV dose and log reduction (inactivation efficiency). 5. Deliver a comprehensive final report detailing velo...

I already have the full schematic for a two-LED flasher and now need it turned into a compact, production-ready PCB. Both LEDs will be mounted off-board, so instead of LED footprints I need two clearly labelled pairs of standard through-hole pads—four pads in total—to solder flying leads that run to the external diodes. The board should remain as small as you can reasonably push it while respecting clearance rules and hand-solderability. Please include a an on/off footprint on the PCB for a switch Mouser part # 633-MS13AFW01 Deliverables • Editable PCB design file (KiCad, Altium, Eagle or similar) • Gerber/NC drill set ready for fabrication • Simple BOM for all on-board parts • PDF plot or 3D view so I can check pad placement before we order boards...

Canada citizen only. This is a remote contract role, and candidates must complete a background check and employment history verification. I have an RTL block, chip or SoC described in SystemVerilog that now needs full functional verification. All verification work must follow UVM, from environment architecture through coverage closure, so that results can be maintained and extended by the in-house team once the contract ends. Scope of work • Build or adapt a complete UVM environment around the supplied DUT, including sequencer, driver, monitor, scoreboard and any passive agents needed for interfaces already defined in the spec. • Develop constrained-random and directed sequences that exercise every item in the functional specification, aiming for 100 % functional and line c...

I have a site plan in AutoCAD (.dwg) and need a precise swept-path analysis carried out in AutoTURN. The focus is strictly on turn and intersection maneuvers, using a custom fire truck profile whose full specifications I will forward as soon as we start. Once the vehicle library file is set-up from my data, please run the necessary simulations across all critical corners, curb returns and interior intersections shown on the plan. I’m looking for clear, publish-ready outputs: • Updated .dwg with the AutoTURN vehicle envelope, axle tracking and overhangs shown on separate, well-named layers • A brief PDF or image set that captures each maneuver with key turning dimensions and any conflicts highlighted I’ll review the drawings for clearance, then sign off when every...

I’m looking for an experienced mechanical engineer to undertake the development of an innovative energy-system project intended for small commercial applications. The project involves developing a novel mechanical energy conversion and storage concept, progressing from engineering analysis and design optimisation through CAD, simulation/FEA and ultimately toward a working, instrumented prototype and a validated design for scale-up. This is an engineering development and innovation project, not a feasibility-study-only assignment. I am not looking for an engineer whose primary deliverable is simply to review the brief, determine whether the initial concept is viable, and produce a development roadmap. The engineering assessment and calculation will naturally form part of the work, b...

I have a straightforward structural analysis question that must be solved in ANSYS during a strict 60-minute window tomorrow, 5 pm–6 pm (my local time, UTC + x). At 5 pm I will send the full problem statement—model geometry, loads and boundary conditions—through chat or email, whichever you prefer. By 6 pm I need the finished Workbench file, a quick screenshot of the key result plot (stress or displacement as required by the prompt), and a brief note explaining the setup so I can reference it later. Because of the tight timing, you should already be comfortable working live in ANSYS Mechanical / Workbench for structural analysis and able to troubleshoot quickly without needing extra clarification. The problem is intentionally simple, so no advanced scripting or user sub-...

I need a working TIA Portal V17 project that lets me test and demonstrate basic control logic on a Siemens S7-1200. The goal is to open the file in my own installation, start PLCSIM (standard or Advanced, whichever you prefer), and watch the logic execute without errors. Scope • Create a clean project with the correct S7-1200 hardware configuration. • Write and comment the fundamental control routines I will specify once we start (start/stop, interlocks, simple timers, fault reset). Keep the code in LAD or FBD so it is easy to follow. • Set up tags and watch tables so I can toggle inputs and observe outputs during simulation. • Provide a brief note inside the project (or as a PDF) explaining how to start the simulation and what to look for. Acceptance I will...

I already have the Inventor model ready and simply need the simulation side taken care of. More details with the right candidate Everything must stay native to Autodesk Inventor so I can continue working with the same files. Turnaround is important; 24 hr delivery

I am building a control solution around a Siemens S7-1200 and need the complete PLC program and matching Siemens HMI screens created in TIA Portal. All logic has to compile error-free, follow Siemens best-practice block structure, use symbolic addressing, and include clear comments so I can maintain it later. Once we start I will share the I/O list, functional description, and network settings; you will return a single TIA Portal project that contains both the PLC and HMI configurations. Deliverables • TIA Portal project file (.ap13 or later) with PLC and HMI fully linked • Export of all program blocks and tag tables • Short PDF explaining program structure, tag mapping, and any special instructions • Video or simulation showing each HMI screen driving the PLC ...

I have a manufacturing assembly line that needs a solid Siemens S7-1500 program so the whole process runs reliably without constant operator tweaks. The PLC will take charge of every step on the line—from feeding parts, through each assembly station, to final transfer—maintaining sequence, interlocks, and safety signals while logging key production data for our MES. You’ll be working in TIA Portal (latest V17 preferred, but I can migrate from V16 if needed). The deliverable I expect is a fully commented PLC project file, tested in the simulator first and then ready for onsite download. If you can include basic WinCC Unified screens for status and fault diagnostics, that’s a plus, but the core focus is the ladder/SCL logic that makes the line cycle smoothly. To acc...
