“…Several recent reports have suggested new methods of aerating shrimp ponds such as wave (surge) aeration (Guan, Liu, Song, & Zhang, 2012), microbubble aeration (Liu, 2017), on‐site oxygen generation and pure oxygen contact systems with aeration control by dissolved oxygen sensors (Nguyen & Matsuhashi, 2019; Tien, Matsuhashi, & Chan, 2019), solar‐powered aerators (Chaithanakulwat, 2019), and submersible impeller aerators (Marappan et al, 2020). These systems have yet to be perfected for use in shrimp ponds.…”

Estimates of aeration energy use in shrimp farming varied from 11.4 to 41.6 GJ/t shrimp (average = 19.8 GJ/t). Several opportunities for reducing energy use in aeration are available. Many farms adopt an excessive yield to installed aeration capacity ratio. Moreover, the proportion of installed aerator capacity in use and duration of aerator operation per day are often more than necessary during the initial two-thirds of grow-out, because adjustment is not made for the quantity of shrimp biomass. Farm-made, long-arm aerators used in Asia have several features leading to energy inefficiency and could be replaced by more efficient factorymade, long-arm aerators. Asian aquaculture aerator manufacturers should redesign aerators to include design features shown in research to improve efficiency. Dissolved oxygen concentration monitoring essential for verification of aeration performance is seldom performed by shrimp farmers. With good aeration technique, energy use for aeration should not exceed 10-15 GJ/t shrimp.

“…This prototype consists of a DC voltage capacitor, current filter inductor, IGBT circuit, gate drive circuit, delay circuit, current detection circuit, and a voltage detection circuit. Accordingly, writing commands for processing with the math model function of MATLAB/ Simulink programs into microcontrollers [24][25][26][27][28][29][30][31]. Moreover, active power and reactive power control with vector simplified optimization techniques based on the D-Q spindle reference frame for single-phase grid-connected inverter.…”

This paper presents the control of grid-connected single-phase inverters with vector control technology based on the D-Q spindle reference frame for photovoltaic systems. This method begins with converting the grid current of the reference sinusoidal signal to a 90degree phase angle and converting it to a DC signal using the clack conversion principle. The aim of this research is to control the current amount of the D-axis vector and adjust the motion angle lag and lead the Q-axis vector. This mechanism control technology uses a microcontroller TMS3020F28379D This allows control of the inverter modulation to supply active and reactive power to the grid. As a result, the power factor in the system can be controlled close to unity. The simulation results using MATLAB / Simulink, compared to the prototype mechanism can confirm satisfactory accuracy.

“…The height and size of modern buildings, especially highrise buildings, limit the natural ventilation, which makes mechanical ventilation and air supply a necessity, and as a result, more and more equipment rooms appear on the roofing of modern buildings [9]. Facing these challenges, architects tactfully extend the glass curtain wall to achieve a shading effect on the roof, improving the exterior design effect of the building without compromising the original layout (Figure 1).…”

Utilization of energy has boosted socio-economic development but meanwhile exacerbated the environmental problems. Offshore areas in China boast abundant solar energy resources. The present work explores the application of solar energy in offshore residential buildings and the ways for integration of solar collectors with the buildings to analyze the potential impact of installation of solar collectors on the design of offshore residential buildings. An extensive design approach that introduces protruding features, outdoor air-conditioner unit spaces, and “virtual” elements into design of residential buildings was proposed, which would integrate the solar collectors into the architectural design and extend the functions of the residential buildings. This research aims to provide a theoretical basis for promoting utilization of solar energy and integrated design of offshore buildings.
