In aqua farms, various parameters of water like temperature, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), acidity, and alkalinity are closely monitored. Biofloc Technology (BT) is adopted, in which specifically cultured microorganisms are introduced into the water to form microbial protein from toxic fish waste and other organic matter to maintain water quality. In the paper "Automated Aqua Farm: Prototype Model with Essential Variables" by G Sakthivel, R Vinotha, A P Prabakaran and A Ragavendiran, an IOT-based real-time monitoring and controlling system is designed for a biofloc fish farm. Using this Arduino Uno microcontroller-based system, the water quality data received from sensors is used to control the actuators through Graphical User Interface (GUI).
High-altitude Electromagnetic Pulse (HEMP) is a sudden electromagnetic energy field caused by the power and radiation of nuclear events and poses a serious threat to electronic devices on various equipment in power systems, aircraft, etc., in military and civilian critical infrastructures HEMP disturbances can damage or destroy both electronic control equipment and the power transformers associated with electric grid distribution; hence, suitable protection is necessary. In the paper "Technical Solutions for Critical Civilian Infrastructure Protection Against HEMP" by Vladimir Gurevich, various protection systems are presented. The protection equipment used in military infrastructure is quite expensive. The author proposes economical HEMP protection equipment for power transformers, microprocessor relays, telecom equipment, UPS systems, and power electronic controllers of diesel generator systems, besides a special testing device to quickly determine the serviceability of UPS after HEMP impact.

MPPT System Based on FTSM and Kgmo for Partial Shading Pv System
The paper makes a comparative study of the four Maximum Power Point Tracking (MPPT) algorithms used for Partial Shading Condition, Conservative MPP, Fast Terminal Sliding Mode (FTSM) controllers and under consistent shading circumstances. In addition, ANN, Kinetic Gas Molecule Optimization (KGMO) and FTSM MPPT are also included. A smart method is to use FTSM GWO algorithms under partly shadowed situations on a global MPP. The study includes a GWO methodology that successfully sets the efficient FTSM controller parameters such that the global maximum PV device powerpoint is monitored under partial shade. In the MATLAB setting and test performance, it is programmed for the suggested methodology of changing shade patterns dynamically. The findings are assessed and compared with ANN, KGMO and FTSM algorithms, and a more accurate method of monitoring the global MPP is found. The methods are also evaluated and contrasted in a PV array under various partial shadowing circumstances. Experimental effects are used to verify the control technique and stability analysis is performed based on the nonlinear method of analysis in the closed-loop design.
Automated Aqua Farm: Prototype Model with Essential Variables
Fish, crab, prawns and other seafood are among the animal-derived foods that are regarded as the safest in contemporary world in terms of enhancing food security. Globally, aquaculture is growing rapidly. India has a big impact on aquaculture due to its proximity to water. In the dynamic context of aquaculture ponds, the interactions between water quality factors are complicated. For instance, unbalanced temperature and pH conditions may make ammonia more dangerous. In poor quality water, fish do eat, but the calories are changed to promote health rather than development. When the water is of high quality, animals can defend themselves most effectively. In this paper, the proposed model monitors and controls fish growth, detection of aquatic animal illnesses and Water Quality Index (WQI). Automated aquaculture employing Arduino and image enhancement techniques are used mainly to spot fish infections. Additionally, management of aqua system is employed to generate high-quality aqua food for customers.
Technical Solutions for Critical Civilian Infrastructure Protection Against HEMP
Protection of critical civilian infrastructure from High Altitude Electromagnetic Pulse (HEMP) at nuclear explosions is significantly different from the protection of military facilities. Therefore, attempts to use well-known military protection means in the civilian sector have failed. The paper analyzes these features and describes new technical solutions designed specifically for civilian infrastructure.
