I have a wireless-power-transfer concept that hinges on a well-tuned antenna, and I want to prove its performance inside CST Studio Suite through a full electromagnetic simulation. The goal is clear: design, simulate, and refine the antenna until the S-parameters, gain, and efficiency meet the power-transfer targets I will share once we start. You will start from my rough dimensions and operating frequency, build a clean 3D model in CST, run the frequency-domain solver, and iterate the geometry or matching network as needed. Along the way, I expect you to explain the choices you make—material settings, boundary conditions, mesh strategy—so I can replicate or adjust the work later. Deliverables • CST project file with all simulations completed • Exported results ...

So its a Dual-Mode Reconfigurable Switched Capacitor Multilevel Inverter (DMRSC-MLI) for on-board electric vehicle (EV) charger utilization. This topology united an adaptive flying capacitor voltage clamping (AFCVC) mechanism with a reconfigurable switched capacitor (RSC) network to generate a high-resolution stepped voltage waveform using a significantly reduced number of active power switches compared to conventional multilevel inverter (MLI) topologies. Unlike traditional Switched Series Parallel Source (SSPS), topologies that rely on an H-bridge for polarity reversal, the proposed architecture employs a self-commutating polarity selection network (SCPSN), operates passively at the fundamental frequency, thereby eliminating 4 additional active switches. Furthermore, the flying capacitor...

I need a batch of custom cables built from scratch, each terminated neatly with the appropriate connectors on both ends. The line will carry a small DC voltage while also handling standard-speed data, so clean signal integrity and reliable power delivery are equally important. You will cut, strip, crimp or solder as required, apply heat-shrink for strain relief, and verify every lead with continuity and load testing before packing. Consistency across the whole order matters more than sheer speed; I’d rather wait an extra day than troubleshoot a cold joint later. Please have your own basic tooling—quality crimpers, multimeter, and, if possible, a simple jig for repeatable length control. When you reply, tell me: • The connector families you keep in stock or can source qu...

Your task is to import the CHEMKIN file, configure the material database to honour those properties, create a stable reacting-flow setup, run it to convergence, and supply the resulting case, data, and a short note that explains boundary conditions, turbulence model, discretisation choices, and residual behaviour. Steady or transient treatment can be your call as long as the final field variables are physically credible and match the supplied rea...

I’m setting up a new firefighting line in Haryana and need a welder who specialises in pipe welding with steel pipes. The job revolves around cutting, beveling, aligning and welding the runs for hydrants, sprinklers and risers so they meet both local safety codes and standard leak-test requirements. You should already be comfortable working on-site around active construction crews, bringing your own basic gear and following standard hot-work procedures. If you hold valid certifications for steel pipe welding or have recent project photos that prove clean, root-penetrated joints, let me know—that will speed up selection. Scope at a glance: • Fabricate and weld the steel pipe network for the firefighting system (grooved and flanged sections included). • Ensure ever...

I’m looking for a single skilled professional who can move seamlessly between pipe welding and front-line fire suppression on an industrial site we’re commissioning. Your primary task is day-to-day pipe welding—cutting, fitting and laying full-penetration welds on steel lines that will feed our firefighting water network. Formal welding tickets are welcome, but I don’t require specific certifications as long as you can demonstrate reliable workmanship and meet pressure-test standards. Because all welding will be conducted around combustible materials, I also need you ready to act as the on-scene firefighter. Solid, current fire suppression techniques are essential; you’ll maintain a constant fire watch and, if an ignition occurs, be the first to knock it down...

I need a CFD-based numerical model that zooms in on how well the liquid desiccant in my solar-thermal dehumidification set-up actually works. The goal is to predict desiccant effectiveness under real operating conditions, with special attention to three tightly linked mechanisms: the adsorption rate inside the contactor, the high-temperature regeneration process driven by the solar loop, and how desiccant concentration shifts over time. You are free to choose any reputable CFD platform—ANSYS Fluent, OpenFOAM, COMSOL, or an equivalent—as long as the final files can be opened and modified later. The geometry is relatively compact (a packed-bed absorber and a separate regenerator), yet the flow is coupled with heat and mass transfer, so please include conjugate heat transfer and ...
