I already have a fully detailed excavator CAD assembly and now need to turn it into a working motion model inside Siemens Simcenter 3D. The scope is limited to the digging and lifting cycle—boom, stick, bucket and their hydraulic actuators—so there is no need to model swing, rotation or travel. Your job is to import or link my CAD, define the joints, masses, centre-of-gravity data, hydraulic cylinders and motion drivers, then run a complete dynamic simulation of one full digging–lifting sequence. I’m particularly interested in actuator loads, reaction forces at the pins, power/energy consumption and overall cycle time, so please set up the appropriate sensors and output requests. Deliverable • A concise performance analysis report (PDF or Word) generated di...

We are looking for a specialist in electromagnetic systems modeling. With real-world experience modeling magnet lead screws, please include an example of your MLS modeling in your proposal.

I am developing a set of brand-new mechanical components in SolidWorks and need a specialist who can take those fresh CAD models straight into Ansys Workbench for detailed structural analysis. The task is to validate strength, identify critical stress regions, and suggest geometry or material tweaks before we freeze the design. You will receive the native SolidWorks files (latest version) plus basic load and boundary conditions. From there, I expect you to: • build a clean finite-element model in Ansys, • run linear static simulations under the supplied loads, • iterate if weak spots appear and propose design changes inside SolidWorks, and • deliver a concise PDF report with screenshots of mesh quality, contour plots, reaction summaries, and your design recommen...

perform a desktop engineering analysis on a standard oil field pump jack (four-bar linkage mechanism) and its associated gear train. The project requires a combination of mathematical modeling, coordinate transformation, and MATLAB programming. You will be provided with a project brief containing site dimensions, coordinate data for specific points and gear specifications. Refer to PDF attached for more details. I will need a full report that is professional and includes he matlab code, referencing etc. Max bid $15 and deadline 2 days, anything else dont bother applying.

I need a fully-functional CODESYS application for a WAGO controller (either 750-885 or 750-8001) that communicates by Modbus TCP whose sole purpose is active fire-systems control. The installation is a multi-medium system; the program must drive individual discharge valves, monitor feedbacks and handle alarms for the selected extinguishing agents: • Water • Gas • Aerosol Key points I expect you to cover – Develop structured, well-commented CFC/ST or LD logic that starts, stops and supervises each medium, including interlocks, pre-discharge delays, abort functions and post-discharge resets. – Build a clean Modbus register map so field devices and the MASTER panel can read status bits and write commands without clashes. – Implement watchdogs, f...

My Gazebo hospital-auction simulation runs three TurtleBot3s under ROS 2 Humble on Ubuntu 22.04. The nodes launch without crashing, NLP commands publish correctly, yet nothing appears or moves in RViz. RViz throws its usual “Global Options → Fixed Frame does not exist” warning, so the TF tree clearly is not reaching the visualiser; after that the robots ignore the velocity messages as well. I need someone experienced with ROS 2 Humble, TF2, Gazebo / Ignition, and TurtleBot3 launch stacks to jump in, inspect the running graph, and eliminate the missing-frame problem so the three bots become visible and responsive again. I have all launch files, URDFs, and NLP command source ready to share over a screen-share or repo. You’d trace the TF broadcasts, confirm the map/odo...

I need an engineer who can take my functional requirements and turn them into clean, synthesizable SystemVerilog that runs on the DE-10 FPGA kit. The work covers the full RTL flow—coding the logic, building self-checking test-benches, running ModelSim simulations, and closing on timing before hand-off. You are free to follow your own coding style so long as the code is readable, well-commented, and synthesizes without warnings. The critical point is that every module is fully verified: all corner cases exercised, assertions in place, coverage collected, and a concise report delivered alongside waveform evidence. I’m based in Ho Chi Minh City and would strongly prefer someone who can meet on-site when needed to review schematics, probe the board, and iterate quickly once t...

I am building a full-path DVB-T2 physical-layer simulation in MATLAB / Simulink and need a clean, well-documented model that demonstrates Adaptive Modulation and Coding using Quadrature Amplitude Modulation. The core emphasis is on the modulation scheme itself rather than error-control blocks or post-detection processing, so the model should let me vary constellation orders (e.g., 16-QAM, 64-QAM, 256-QAM) and observe the impact on throughput and BER under different channel conditions. Key elements I need: • A runnable Simulink (.slx) file that instantiates the complete DVB-T2 baseband chain up to the QAM mapper, includes channel impairment blocks (AWGN, fading), and ends with demodulation so I can plot BER and EVM. • Parameter masks or scripts that let me switch constellation...

I’m putting together a lightweight, consortium-based blockchain layer to decentralize the control plane of a software-defined vehicular ad-hoc network (VANET) for ddos attack. The architecture must place enhanced security front and center—specifically, it has to guarantee data integrity, robust authentication and strong privacy protection for every message that moves between vehicles, roadside units and cloud edges. Because we are working with a consortium blockchain, I expect permissioned membership management, rapid consensus and low latency that fits the tight timing windows of vehicular communication. Open public chains are off the table; the solution has to remain controllable by a defined set of stakeholders such as OEMs, infrastructure operators and municipalities. Her...

I need a fully-parameterised ASPEN Plus V14.2 model that captures the key biological steps of anaerobic digestion so I can observe how the plant responds when I vary two levers: substrate concentration and hydraulic retention time. My core interest is methane production, so the flowsheet must report CH₄ flow rate (Nm³ h⁻¹ or similar) at every run and allow easy extraction of the data for comparative plots. Your task is to build, validate and hand over: • the working ASPEN Plus (.bkp) file with all relevant property methods and reaction kinetics implemented, • a concise run guide that shows where and how to change the two investigated parameters, and • a brief results note or dashboard (Excel, MATLAB or embedded Aspen Analysis) illustrating at least three op...

I want to turn our in-house gas-turbine know-how into an engaging, self-paced online course built entirely around interactive modules. Your job is to design and develop those modules so learners don’t just watch—they experiment. The core of each lesson must be simulation driven. Trainees should be able to click through virtual engine bays, strip components, reassemble them, and see immediate feedback on what went right or wrong. Drag-and-drop activities will reinforce part identification, torque-sequence orders, and seal placement. I also need decision-based scenarios that ask, “Would you proceed with this clearance reading?” or “Which risk mitigation step comes next?” and then show the consequences. At any point learners must be able to pull up technic...

Low Power, High Speed,Area Efficient Multiplier based on the PTL logic style is the project title.I have to implement using cadence virtuoso gpdk090 nm technology and I want improvement of this paper for paper publishment.

I need you on the plant floor in Egypt to expand an existing Siemens S7-300 program by roughly twenty new points of mixed I/O. The work is purely control logic— no additional safety layer— and must integrate cleanly with the current STEP 7 project. Once the code is in place, create a single WinCC operator page that displays and allows basic control of those new points. Keep the look-and-feel in line with the existing HMI screens so the operators do not notice any stylistic jump. Because this job involves downloading to the live PLC and verifying signals on the physical panels, I can only accept someone who already resides in Egypt and can be on site for commissioning. Deliverables • Updated S7-300 program with the twenty mixed I/O points fully documented • ...

What the project is A comparative structural impact study of three lightweight occupant-cell concepts for a small side by side 2 seater urban vehicle: 1. Tubular frame (aluminium) 2. Monocoque frame (preferably carbon or maybe polyurethane like foam filled stuff) 3. Hybrid redesign based on the weaknesses found in 1 and 2 The occupants are side-by-side in every case. The impact speed is 28 mph (45 km/h) in every case. The impact conditions are: • frontal impact • side impact The purpose is to find which concept gives the best occupant protection for a lightweight design.

I need an Aspen simulation that focuses on full process design of a heat exchanger network. The goal is to build an accurate model and deliver a detailed thermal performance evaluation: temperatures, duties, pinch points, approach temperatures, and any bottlenecks that appear once the network is integrated into the overall process flow. You may work in Aspen Plus or HYSYS for the main flowsheet and use Exchanger Design & Rating (EDR) or Energy Analyzer for the network itself—whichever produces the most reliable convergence and reporting. Please document every assumption (fluid properties, fouling factors, pressure drops) directly in the model notes so I can reproduce your results. Acceptance criteria • Complete Aspen file(s) with all units converged • Thermal perfor...

I need a control-systems specialist to build a Model Predictive Controller for a wind turbine that I have already represented as a Linear Parameter-Varying (LPV) model in MATLAB/Simulink. The controller must juggle three objectives at once—maximising electrical power output, keeping mechanical stress to a minimum, and sharpening pitch-angle accuracy—while remaining robust to real-world disturbances such as wind-speed fluctuations, grid faults, and the occasional mechanical component hiccup. The core work happens in MATLAB/Simulink: setting up the prediction model, formulating the multi-objective cost function, and implementing hard or soft constraints that reflect turbine limits and grid-code requirements. I will provide the LPV model and any necessary operating data; you desi...

I have a Unitree Go2 and need it to navigate outdoors without manual input. The focus is straight-forward: build and integrate a ROS 2 solution that lets the robot plan, localise, and execute safe paths across natural terrain. You are free to leverage the Nav2 stack, slam_toolbox, or any other ROS 2 packages that suit the task, as long as the end result runs reliably on the Go2’s onboard computer and works with its existing sensors. Deliverables • ROS 2 workspace with all custom nodes, launch files, and parameter sets • Clear build & deployment instructions (README or tutorial video) so I can reproduce the behaviour on a fresh system • Short live demo or rosbag proving the robot can start, plan, and reach a goal point over outdoor ground (grass/gravel) witho...

I already have a fully functioning Siemens S7 / TIA Portal project that drives an industrial colour-mixing line, with WinCC handling the on-site visualisation and Factory IO used for simulation. The core control logic and HMI screens are finished; what I now need is an experienced WinCC engineer who can extend the system with three concrete additions: rich reporting & analytics, a structured alarm-management layer, and secure remote-control capability. Reporting & analytics • Build dashboards and historical reports that highlight mixing-process efficiency, long-term sensor-data trends and detailed downtime analysis. These reports must be accessible directly from WinCC and exportable to common formats (PDF, CSV). • All calculations should run in real time so operators...

I am building a cinematic blast sequence and need solid data-driven support rather than eye-balling particle emitters. The idea is to run an AI/ML simulation that predicts how metal, glass, concrete, wood and plastic fragments fly away from the detonation point, then turn those numbers into clear data-visualisation charts I can hand directly to the FX team. Scope • Direction, speed and distance must be predicted separately for each material class, following the colour code I already use on set (red = metal, blue = glass, grey = concrete, orange = wood, green = plastic). • The charts have to highlight the mean and standard deviation for every variable so the artists immediately see the “typical” trajectory as well as the natural spread. Other metrics such as perce...

I am preparing a detailed multi-body simulation focused on the dynamics of the power transmission in a manual transmission and the crankshaft assembly. I urgently need an engineer who can: • Build a robust multibody model of the connecting shafts and input components of the gear train for a 5-speed manual transmission, the crankshaft assembly, • Run steady-state and transient analyses to capture torsional vibration, imbalance forces, and bearing loads • Document all assumptions, material properties, and boundary conditions so results are fully traceable • Recommend design tweaks if critical speed or NVH issues appear in the results Adams and Simpack, experience with either package is a bonus, but I’m also open to other comparable platforms if you can just...

I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...

I need a skilled CAD engineer to turn my drone concepts—and a few companion pieces of field equipment—into a fully-featured 3D simulation. The model has two equally important jobs: first, to let me stress-test aerodynamics, weight distribution, and moving parts in a virtual environment; second, to present polished visuals that can impress investors and non-technical stakeholders. You will start from dimensioned sketches, reference photos, and a performance brief. From there, create a parametric model in the CAD platform you are most comfortable with (SolidWorks, Fusion 360, Creo, or similar are all fine) and build in the motion studies, FEA/CFD or other analysis needed for credible performance testing. When the numbers work, add photoreal textures, lighting, and camera paths s...
