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...

We are looking for an experienced PLC Programmer and Hardware Integrator with strong expertise in Modbus communication to support an automation project. Scope of Work: * Develop and implement PLC programs * Integrate PLC with field hardware (sensors, actuators, controllers) * Configure and troubleshoot Modbus (RTU/TCP) communication * Ensure reliable data exchange between devices * Support system testing and debugging Requirements: * Proven hands-on experience in PLC programming * Strong experience in hardware integration and wiring interfaces * Solid understanding of Modbus communication (RTU & TCP/IP) * Experience with industrial automation systems * Ability to troubleshoot communication and integration issues Preferred: * Experience with multiple PLC platforms (Siemens / Allen...

I need two weather-rated Ubiquiti access points mounted outside my home and connected to my network. I have 2 Orbi units indoors, though would consider changing. I may need a new poe switch. Scope of work • Supply and mount two exterior-grade Ubiquiti APs (UniFi Mesh or another model you recommend) on the soffit/eaves for broad yard coverage. • Run Cat-6 or Cat-5 cabling back to a new PoE switch, keeping the runs neat and protected from the elements. • Configure the APs in the UniFi controller (?) so the SSID, guest network match my current indoor setup. • Verify roaming, signal, and security outdoors once everything is live. Acceptance criteria 1. Both units are visible in the UniFi dashboard (?). 2. Outdoor coverage reliably reaches areas where outdoor ...

I’m bringing a brand-new Arista DCS-7050SX3-48YC8-F online and need a smooth software rollout under EOS. The hardware is already on site and cabled, so the engagement is strictly about software configuration. Here’s what I need: • Guide me through the initial boot process, image verification, and any Zero-Touch Provisioning or USB methods you prefer. • Build a clean, best-practice base configuration that covers management VLAN, access and trunk ports, STP, basic L2/L3 features, and secure remote access (SSH, RADIUS). • Provide a concise recommendation on the LIC-FIX-2-E licence—when it becomes essential, what functionality it unlocks for this model, and the most practical route to purchase and apply it. Deliverables will be the final running-con...

Short Summary of the Research This research focuses on designing a high-gain antenna for 5G communication at 36–38 GHz (millimeter-wave). Since 5G at these frequencies suffers from high signal loss, the study aims to improve signal strength using an efficient antenna design. The proposed solution is a compact stacked slot antenna, which provides: Wide bandwidth (34–44 GHz) Stable radiation pattern (consistent signal in all directions) Minimum gain of ~6 dBi (higher in arrays) To improve performance, the antenna is developed in three stages: Single antenna element – basic design and testing 1×2 array – increases gain by ~2–3 dB 1×4 array – further improves gain (~6 dB increase overall) The study proves that increasing the number of antenna ele...
