    Agricultural Ecosystem Monitoring Based on Autonomous Sensor Systems

    More than two-thirds of freshwater consumed worldwide are used for irrigation, and large quantities of freshwater can be saved by improving the efficiency of irrigation systems. Irrigation control systems deployed in agriculture can substantially be enhanced by implementing intelligent monitoring techniques enabling automated sensing and continuous analyses of actual soil parameters. Automatically scheduling irrigation events based on soil moisture measurements has been proven an effective means to reduce freshwater consumption and irrigation costs, while maximizing the crop yield. Focusing on decentralized autonomous soil moisture monitoring, this project presents the design, the implementation, and the validation of a low-cost remote monitoring system for agricultural ecosystems. The prototype monitoring system consists of a number of intelligent wireless sensor nodes that are distributed in the observed environment. The sensor nodes are connected to an Internet-enabled computer system, which is installed on site for disseminating relevant soil information and providing remote access to the monitoring system. Autonomous software programs, labeled “mobile software agents”, are embedded into the wireless sensor nodes to continuously analyze the soil parameters and to autonomously trigger irrigation events based on the actual soil conditions and on weather data integrated from external sources.

    Design, Development and CFD Analysis of Hot End Extruders Heat Sinks
    (2020-09-19T08:14:50Z) Abhishek, N; Keshava Kumar, M; Prathik Kumar, B
    At present the Additive manufacturing is the innovative technology in manufacturing industry for its cost effectiveness, portability, and its environment friendly and bio-degradability, it has some predominant factor affecting the build quality which needs to be taken into consideration.Our primary focus is to ensure the right amount of heat is supplied from the heater block, and the required amount of heat is absorbed in the melting process and dissipated appropriately making the Hot end extruder suitable for all types of Filaments including those with metal reinforcements as well, provided the 3D printer being set to the optimal settings. Our Project mainly focusses on the development of the extruder with Al 2024 MMC and simulating both the stock material and the MMC material for comparison. The procedure consists of designing, development and CFD analysis for both the stock material of Al 6061 and Al 2024 MMC.
