Aquaculture is so sensitive to environment thus failing to control the water quality often causes big losses on farmers. This research proposes a combination of sensor technology, ICT and cloud service for effective management including GAP report generation. Monitoring water quality and good management based on Good Agriculture Practice (GAP) will definitely improve aquaculture productivity and secure food safety. An aqua sensor platform and farm management software based on GAP were developed to support aqua farmers and aqua-researchers. The acquired sensor data is not only visualized but also analyzed to provide early warnings to the farmers. An alert message will be sent out when observed values have reached thresholds so that a farmer can take appropriate actions before possible damages. The system provides a template to record aqua farm activities such as preparation, feeding food, which are required for GAP report. This solution will be the foundation of smart aquaculture and will contribute to better management, production and food safety.

Cu2ZnSnS4 (CZTS) based thin-film photovoltaic (PV) cells are suitable candidates for PV cells since CZTS (as absorber material) has an easily tunable bandgap, is nontoxic and economical. Using the Back Surface Field (BSF) layer is one of the primary methods of upgrading the efficiency of PV cells. The BSF layer reduces the wastage of photo-generated electrons at the back recombination sink, and hence improves the efficiency of the cell. engineering Mo/CZTS interface is very crucial for the performance of PV devices © 2020 IEEE.

This study evaluated the efficiency of activated carbon (AC) for nitrogen removal, aiming to enhance nitrogen removal under low-temperature conditions to address ammonia-nitrogen pollution in northern alpine regions. Elemental iron, in the form of Fe 2 O 3 , was loaded onto activated carbon (Fe-AC) using an ultrasonic impregnation method, and the modification effects were systematically investigated. The superiority of the modified activated carbon in low-temperature environments was assessed by comparing its adsorption performance, surface physicochemical properties, biofilm formation, and nitrogen removal efficiency with those of unmodified activated carbon. The results demonstrated that iron loading significantly altered the pore structure and surface chemistry of the activated carbon, enhancing its ammonia-nitrogen saturation adsorption capacity. Notably, at a low temperature of 5 °C, the adsorption performance reached 52.8 %. The adsorption process adhered to the pseudo-second-order kinetic model, and thermodynamic analysis indicated that the process was spontaneous and exothermic. Under low-temperature conditions, the modified activated carbon achieved biofilm formation 10 days faster than the unmodified carbon, with an ammonia-nitrogen removal rate exceeding 95 %. Furthermore, the number and activity of microorganisms were markedly increased, leading to an ammonia-nitrogen degradation rate of 0.114 nmol P/g significantly higher than the 0.090 nmol P/g observed for the unmodified carbon. Fe-AC improved nitrification performance in low-temperature environments by enriching the microbial community structure. Overall, the modified activated carbon substantially improved nitrogen removal efficiency under low-temperature conditions, demonstrating broad application potential for addressing ammonia-nitrogen pollution in cold regions.

Photovoltaic (PV) energy is the most vital renewable energy sources, and it has appeared as a feasible solution to the world's energy issue. This paper proposes a sophisticated PV integrated architecture including a coupled inductor based second order buck-boost converter, synergized with a particle swarm optimized proportional integral (PSO-PI) controller. With its ability to handle a broad range of input voltages, the converter's topology is designed to reduce energy losses and improve overall system efficiency. The objective is to guarantee excellent power quality and improve system reliability. To further improve performance, the system also includes a PI controller that is supported by PSO. The output is delivered to the grid via a single-phase voltage source inverter and grid synchronization is attained by the PI controller. The developed research is validated in MATLAB/Simulink and comparison with traditional approaches is conducted. The observed results show better converter efficiency of 92% with higher performance in terms of power quality enhancement. © 2024 IEEE.

Meditation is a family of ancient and contemporary contemplative mind-body practices that can modulate psychological processes, awareness, and mental states. Over the last 40 years, clinical science has manualized meditation practices and designed various meditation interventions that have shown therapeutic efficacy for disorders including depression, pain, addiction, and anxiety. Over the past decade, neuroimaging has been used to examine the neuroscientific basis of meditation practices, effects, states, and outcomes for clinical and nonclinical populations. However, the generalizability and replicability of current neuroscientific models of meditation have not yet been established, because they are largely based on small datasets entrenched with heterogeneity along several domains of meditation (e.g., practice types, meditation experience, clinical disorder targeted), experimental design, and neuroimaging methods (e.g., preprocessing, analysis, task-based, resting-state, structural magnetic resonance imaging). These limitations have precluded a nuanced and rigorous neuroscientific phenotyping of meditation practices and their potential benefits. Here, we present ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis)–Meditation, the first worldwide collaborative consortium for neuroscientific investigations of meditation practices. ENIGMA-Meditation will enable systematic meta- and mega-analyses of globally distributed neuroimaging datasets of meditation using shared, standardized neuroimaging methods and tools to improve statistical power and generalizability. Through this powerful collaborative framework, existing neuroscientific accounts of meditation practices can be extended to generate novel and rigorous neuroscientific insights that account for multidomain heterogeneity. ENIGMA-Meditation will inform neuroscientific mechanisms that underlie therapeutic action of meditation practices on psychological and cognitive attributes, thereby advancing the f

Extreme rainfall events are becoming increasingly severe under a warming climate. North China has experienced several catastrophic rainfall events, of which the rainstorm in 2023 was particularly severe inducing unprecedented damage. Since 1980, the neighboring Mongolian Plateau (MP) has been warming at a rate three times the global average, faster than the surrounding regions. Whether a link exists between extreme rainfall in North China and the fast MP warming is unknown. Here, using global variable-resolution atmospheric model with convection-permitting capability over North China, we find the rapid warming trends, particularly over the MP, are highly conducive to extreme rainfall over North China. In the 2023 case, the fast MP warming induced an anomalous terrestrial high, which in the Western North Pacific Subtropical High created a strong high-pressure system over North China. This system obstructed northeastward movement of Typhoon Doksuri, concentrating moisture supply which prolonged and intensified the extreme. © 2025. The Author(s).

Software Defined Networking is the innovation in the network which allows us to manage the network dynamically in an efficient way. Ternary Content Addressable Memory (TCAM) is being used by the OpenFlow switches because it is faster look-up. However, it is very costly, and also the number of flow entries accommodated in it is less due to its limited size. So to take full advantage of the TCAM, we need to maximize the flow table utilization. To improve the TCAM allocation, This paper emphasizes managing the Hard Timeout of the flow table entries. We are proposing a Dynamic way to allocate the flow entry timeout so that the flow table can be used optimally by assigning different dynamic timeout considering predictable and unpredictable flows. The results show that Dynamically allotted hard timeout along with LRU as the eviction method performs better than the Statically allotted hard timeout along with LRU. © 2019 IEEE.

We present a new simple approach to extend the admissible region of a saturated control law for discrete-time linear systems under state and input constraints. The approach is based on the interpolation of a given, performance driven, control law and a low-gain controller. The latter is designed such that its admissible set has maximum volume. The interpolation does not require on-line numerical optimization, and an analytical formula for the controller is given. Several numerical examples are presented to illustrate the control technique. © 2018
