Why People Can Always Tell When AI Wrote Your Text
Young adults are letting ChatGPT draft their texts and hard conversations. Here's why it's obvious and what actually works instead.
Simulation is the process of creating a model of a system, such as a network, environment, or process flow, where variables can be experimented with to gather data and to analyze the outcome. A Simulation Engineer enables their client to research and validate the theoretical predictions with different test scenarios before putting those theories into actual practice. They can provide their clients with highly relevant data gathered from simulation to help make decisions with maximum efficiency in fields such as product design, system optimization, and vehicle engineering.
Simulation is used in almost every industry as it offers flexibility and accuracy in experiments to make sure that the design under consideration is secure and able to accomplish tasks effectively. An expert Simulation Engineer is an invaluable asset when it comes to creating accurate simulations based on theoretical equations - they can make sure these simulations are sufficiently up-to-date and that there is consistency in the data collected by these tests.

De 9,016 opiniones, los clientes califican nuestro Simulation Engineers 4.84 de un total de 5 estrellas.I need an implementable approach that lets a swarm of autonomous drones discover the most efficient path through AI technologies in a busy urban landscape while constantly negotiating dynamic obstacles such as cars and pedestrians. The emphasis is on efficiency rather than simple collision-free travel, so your solution should balance travel time, energy usage and real-time rerouting without spreading the drones too far apart. I am open to a bio-inspired technique—ant colony optimisation, particle swarm, artificial bee or a hybrid—so long as it scales cleanly from small (5–10 drones) to medium fleets (50+). Please choose libraries and simulation tools you are confident with; ROS 2, PX4, Gazebo, Webots, Python fine if they help you deliver quickly. Deliverables • W...
We are a team of Electrical Power Engineering students looking for an experienced engineer or academic expert to help us identify and evaluate a strong graduation project idea. We are mainly interested in projects related to: Power Systems, Protection, Power Quality, Distribution Systems, Motor Drives, Fault Detection, Automation, Grid Reliability, and Smart Power Systems. The project should: * Solve a real and relevant electrical power problem * Include a practical physical prototype * Include a meaningful simulation using tools such as ETAP, MATLAB/Simulink, PSCAD, or similar * Be feasible for a student team within approximately 4–6 months * Have reasonable hardware cost * Be technically strong and suitable for a final-year graduation project * Preferably improve an existing sol...
Neo-Hookean is suitable as a starting hyperelastic material model for snap-through structure, especially if we are using a TPU/rubber-like material and the strain level is not extremely high. start with Neo-Hookean for the baseline ANSYS model because it is simple, stable, and easy to calibrate. Then, if my experimental TPU data shows large nonlinear deformation that Neo-Hookean cannot match well, compare it with Mooney–Rivlin or Ogden. For snap-through analysis, the important point is that the material model must handle large strain + large deformation. Neo-Hookean does this much better than a simple linear elastic model. but “A Neo-Hookean hyperelastic material model was initially selected to represent the nonlinear elastic behaviour of the TPU structure under large deform...
I need a Simulink model that lets me design and test a full state-space control system in both continuous-time and discrete-time forms. The goal is to compare the two implementations side by side inside the same project so I can evaluate performance, stability margins, and implementation effort before moving to hardware. I will provide the plant dynamics and desired performance indices as soon as we start. From there, I’d like you to: • Build the continuous-time state-space controller in Simulink, organised with clear subsystems for A, B, C, D matrices and any pre-compensators or observers you feel are appropriate. • Create the matching discrete-time version (sample time will be specified) and place it in a parallel branch of the model for direct simulation comparison. ...

I need a fast-turnaround electromagnetic FEA study on my “Tab-and-Stab” electric motor concept and have already prepared the full CAD geometry. Your task is to import that model into ANSYS Maxwell, set up a 3-D transient solver, and tell me exactly how efficiently the machine performs when subjected to variable loads across the intended speed range. Scope • Set up materials, winding definition, and boundary conditions that match the data I’ll provide. • Run efficiency sweeps from light to peak torque, capturing any saturation or flux-leakage effects caused by the tab-and-stab laminations. • Return post-processed plots (efficiency maps, torque-speed curves, loss breakdown) plus the *.maxwell or *.aedtz file so I can reproduce the run.

Title: CLO 3D Production Operator – Bulk Blouse File Processing We are looking for CLO 3D Production Operators for a large-scale, ongoing blouse project. This is not a garment design or pattern-development role. All required blouse designs, DXF patterns and CLO source files will already be created and provided by us. The work is a structured CLO 3D production-processing task. You will need to follow our fixed workflow accurately and consistently. Main Responsibilities: * Open the CLO source file provided by us * Import the respective DXF pattern * Sew the required front / back / sleeve pattern with the existing frozen parts * Do not move, modify, delete or unfreeze any frozen elements * Set the required Particle Distance and simulate the garment * Follow the specified front/back vi...
I have a power-board inverter destined for a modern battery-electric vehicle and I need a complete thermal solution developed around it. The work starts with accurate 3-D modelling of the board, then moves into designing an aluminium heatsink that houses an internal liquid-coolant channel. Every design decision must be validated in ANSYS/COMSOL, as that is the simulation environment we use in-house. The study has three inseparable goals: maximise heat-dissipation efficiency, keep every critical component within its target temperature window, and optimise the coolant flow path so pressure drop stays reasonable. You are free to choose the most suitable ANSYS modules—Icepak, Fluent, Mechanical, or Workbench—as long as the final package covers both conjugate heat transfer and CFD....
I am preparing a research article on the estimation of several entropy measures for the Inverse Power Half-Logistic distribution under an Upper Record Ranked Set Sampling scheme. The work must develop Bayesian, non-Bayesian and expected Bayesian estimators, assess them through a thorough Monte-Carlo study, and demonstrate their practical value on real data. You will write the complete manuscript and supply every line of code that leads to the reported numbers and figures. My preferred workflow uses both R and Python, so feel free to split the analysis between, for example, tidyverse / rstan in R and numpy / scipy / matplotlib in Python, provided the results match. The paper should follow the structure: Abstract, Literature Review, Methodology, Conclusion, and be typeset in LaTeX (with a...
I want to turn the often-dry topic of financial statement preparation into an engaging, simulation-style video game that accountants in training can use for self-paced learning. The core mechanic should mirror real-world accounting cycles: players receive source documents, post to journals and ledgers, adjust entries, then generate the income statement, balance sheet, and cash-flow statement. Each action needs immediate visual feedback and scoring so users see how every choice affects the final reports. Because the primary goal is training and education, accuracy comes first. All calculations, classifications, and closing procedures must follow GAAP. If you’re using a game engine such as Unity or Unreal, please build the underlying accounting logic in modular scripts so it can be au...
I am a junior design-verification engineer working on projects that rely heavily on UVM and SystemVerilog. The scope of my day-to-day work shifts—from setting up testbenches and drafting verification plans to digging through waveforms when bugs appear—so I’m looking for an experienced engineer who can step in whenever a challenge arises. Here’s what I need from you: • On-demand problem-solving whenever I hit a roadblock, whether the issue is in stimulus generation, coverage closure, or a stubborn simulation mismatch. • Broader guidance and mentorship that helps me grow: reviewing my overall approach, suggesting best practices, and explaining why a particular methodology choice matters. Code reviews are welcome when time permits, but the primary focu...
I am expanding an existing embodied-AI stack and now want to double-down on Vision-Language-Action modelling. The core goal is to design, train and scale a full pipeline that takes raw multimodal data, learns a joint representation and closes the loop all the way to real-time action on a physical robot. You will start from large, messy datasets (images, video clips, proprioception, language annotations) that already sit on our cluster. The job is to craft a new architecture in PyTorch, schedule distributed training, and iterate until the model achieves reliable closed-loop visuomotor reasoning in simulation and on hardware. Robust multimodal representation learning, a world-model/JEPA component, temporal memory, and predictive control need to come together in a single, maintainable codeba...
I’m producing an animation film that features several human characters captured in close-up, and I need their hair to move and react with convincing realism. The project is already modeled and groomed; what’s missing is a polished Houdini Vellum setup that can carry the weight of cinematic shots—slow-motion turns, fast head snaps, wind gusts, and subtle secondary motion for quieter moments. Here’s what I’d like from you: • Build or refine a Vellum Hair network that keeps strand shape integrity while allowing believable stretch, bend, and collision. • Provide clear parameters I can tweak for scene-specific variations (stiffness, damping, drag, wind influence, etc.). • Deliver a clean .hip file (or HDA if you prefer) plus any geometry caches...
