I need a concise, production-ready program written in WPLSoft for a Delta DVP-series PLC. The sole objective is to automate a manufacturing process that is currently handled manually, so the logic must cover all machine sequences, safety interlocks, start/stop routines, and alarm handling. You will receive a full I/O list, basic wiring diagram, and the intended sequence of operations the moment we start. Your task is to translate that sequence into ladder logic (or sequential function chart if you prefer) inside WPLSoft, simulate it to prove the timing, and then provide the downloadable .DVP project along with a brief commissioning guide so my on-site technician can load, test, and fine-tune it. Key expectations • Program must be created in WPLSoft and match the Delta DVP comm...

I want a fully flyable eVTOL model inside X-Plane that I can use to train future pilots of a Part 103-compliant ultralight. The aircraft has eight electric motors and is steered with two independent joysticks—one dedicated to ascent/descent plus turning, the other to forward/reverse and roll—with a hands-off hover mode in between. The heart of the job is getting the flight dynamics right. I need the model to reflect true ultralight behaviour under the Part 103 envelope while accurately blending the thrust from all eight rotors. Control response on both sticks must feel natural and symmetrical so that student pilots can translate hours in the sim directly to the real seat. You are free to use Plane-Maker, X-Plane’s Experimental Flight Model, custom data-refs, or a pl...

I need a Verilog-HDL RAM module that meets an already defined specification. The core requirement is a synchronous memory unit with reliable read/write control. Beginning from the RTL, I want clean, synthesizable code, followed by a self-checking testbench that proves functional correctness across corner cases. Your workflow should include: • RTL implementation of the RAM with parameterised depth and width • A functional testbench that drives realistic stimuli and automatically flags mismatches • Simulation runs in ModelSim or an equivalent simulator, with waveform capture for review • Iterative debugging until the waveforms reflect the expected behaviour • Concise documentation explaining interface signals, timing, and any design decisions Address decodi...

I am building a proof-of-concept rover whose only job is to prove that controlled, repeatable motion is possible inside transformer oil. To make that happen I need a complete blueprint package—detailed engineering drawings rather than a simple overview—showing exactly how to propel, steer, and recover a small test vehicle submerged in this highly viscous fluid. Rather than propellers, tracks, or wheels, I want the craft to move by exploiting buoyancy. Your design should use the density difference between the rover and the oil to generate thrust and directional control. This should not create any bubbling in oil while movements. Critical elements of the buoyancy control system that must appear clearly in the drawings • Adjustable weights • Air / water pumps Ev...

I run a complex System-on-Chip project and reserve about four hours each week for focused progress. During that window I rely on an experienced engineer who can jump straight into SystemVerilog / UVM code and keep our verification flow tight. The core of the session is SoC-level development, yet every task circles back to solid design-verification practice: • Testbench development that plugs cleanly into our existing UVM environment • Live simulation and debugging, spotting corner-case failures as they appear • Coverage analysis and closure so we meet functional goals with data-driven confidence Remote pair-programming over a shared workspace works best for me; I’ll have source, waveforms, and spec documents ready before each call so we can spend the full four...

I need a compact, high-performance microstrip antenna engineered specifically for satellite communication in the mmWave region. The goal is to move from concept through full-wave simulation to fabrication-ready files while meeting tight performance targets on gain, bandwidth, and axial ratio. Scope of work • Electromagnetic modelling and optimisation in a recognised solver such as HFSS, CST, or similar, covering the exact mmWave band that satellite links typically occupy. • Substrate selection with justifications (εr, loss tangent, availability). • Impedance matching network design to maintain ≤-10 dB return loss across the operating band. • Radiation pattern validation for both boresight gain and sidelobe levels suitable for satellite uplink/downlin...

I am working through Eleation’s HyperWorks course and have 50 pending assignments that must be wrapped up as quickly as possible. Each task follows the standard Eleation template—import the part, create a clean mesh, apply the given boundary conditions, run the required solver (primarily OptiStruct and Radioss), then export results and brief observations. Because this is purely for my personal up-skilling, accuracy and clear step-by-step files matter more than polished presentation. If you have solid, hands-on experience with Altair HyperMesh, HyperView, OptiStruct and Radioss, you should find the workload straightforward; please highlight that experience in your bid. Deliverables • Fully solved model files for all 50 assignments (native .hm, .fem, solver decks) ...

I will provide a clean set of chamber dimensions together with partial data for the inlet, centrifugal fan and rectangular outlet. Your first task is to build the 3-D model in SolidWorks from those numbers, filling in any missing inlet or outlet detail after we agree on reasonable assumptions. Once the geometry is ready we move straight into Flow Simulation: • Case 1 – baseline airflow through the empty chamber • Case 2 – same model with the gas-sensor array added • Case 3 – sensors plus guiding walls on both sides • Honeycomb comparison – overlay 1.5 mm vs 2 mm perforated inserts and report the effect on flow and sensor exposure For every run I expect the native *.FlowSimulation project, pressure/velocity plots, streamlines, and a short...
