Here is the flow I have in mind: • Edge device pushes sensor readings via cellular data to a secure backend (MQTT or HTTPS—use what you are most comfortable with). • Backend stores, normalises, and exposes that data through an API. • A web or mobile dashboard pulls the feed and displays key performance metrics with alerts when values drift outside preset thresholds.

    I’m running an InHand IG502 cellular gateway and need a focused Python add-on that exposes the unit’s current RSSI (raw dBm) as a holding register inside the built-in Modbus server. The immediate aim is simply to monitor signal quality; once the value is available we will pass it through our existing RS-485 link into the DNP3 layer of the external SCADA. Key points you should know while coding: • Device: InHand IG502 (OpenWrt-based, Python 3 available). • Output format: raw signal strength value, no scaling or percentage. • Register must be readable via Modbus-TCP and Modbus-RTU so I can map it downstream. Byte order can be little-endian; just document what you use. • Communication onward to DNP3 happens on my side, so the script only has to po...

    ...data-throughput paths, richer network-management options, and extra data interfaces such as serial ports and general-purpose I/O. All new code must interoperate with the OEM’s own proprietary protocols, so every build needs to be exercised against their closed, in-house stacks. Our immediate need is rigorous quality-assurance and debugging support throughout the development cycle. Your job is to design and run repeatable tests and make sure we meet customer's objective, and feed concise feedback and bug reports to the factory team. Expect iterative rounds of validation on both bench setups and pre-production hardware. Once the firmware reaches release status, the routers roll straight into a large deployment running to several hundred units. At that stage we’ll...

    ...seamlessly on both iOS and Android. You will receive the current code-base, Figma screens, and the LiveKit cloud instance that is already running. I need you to hook everything up—permissions, token generation, room management, connection state handling—and expose a clean set of components I can reuse anywhere in the app. Calls must remain active in the background, switch gracefully between Wi-Fi and cellular, and respect the platform guidelines for camera and microphone usage. Deliverables • A drop-in React Native module that wraps LiveKit’s audio/video functions • Basic call UI: join screen, in-call view, mute/camera toggle, end call • Thorough README and inline comments so the team can extend the feature on its own • Final build va...

    ...16-minute VSL and give it a premium medical polish without disturbing a single beat of the existing script or timing. The main tasks are: • Burn clean, highly legible subtitles (white text on a dark, semi-transparent bar) and subtly pick out important keywords in a soft gold/yellow accent so viewers immediately grasp the big ideas. • Weave in scientific animations that depict real cardiac function, cellular activity, inflammation, and other internal processes. The look must feel serious and clinical—think textbook-grade anatomy rather than playful explainer graphics—because the VSL revolves around disease-prevention insights and specific medical treatments. The overall aim is sharper clarity, stronger viewer retention, and higher conversions within my sal...

    Wet Lab 2 For Wet Lab 2, you performed a Gram stain to differentiate bacterial species based on their cell wall properties. As part of this assignment, you are required to submit the following: 1. 2. 3. A clear photograph of your stained specimen under the microscope. A hand-drawn sketch (labeled) of your specimen, accurately depicting the observed cellular morphology and arrangement. A short write-up (approximately 100-300 words) discussing your observations. Your discussion should include: o A description of what you observed under the microscope, including cell shape, arrangement, and Gram reaction (positive or negative). o An explanation of your observations based on the principles of Gram staining. o Any potential sources of error that may have affected your results. Grading Cr...
