Biomarkers in neurophysiological signals can be analyzed to determine indicators of mood disorders for diagnosis. In this paper, EEG signals were analyzed from a public database of 119 subjects ages 18 to 24 performing a cognitive task. 45 subjects had moderate to severe anxiety and/or depression and the remaining 74 subjects had minimal or none. A...

Urban densification and climate change are creating a multitude of issues for cities around the globe. Contributing factors include increased impervious surfaces that result in poor stormwater management, rising urban temperatures, poor air quality, and a lack of available green space. In the context of volatile weather, there are growing concerns...

... Further, it is poosible to ensure early detection of Dyslexia using BCI which in turn helps in treating the children and improve their self-confidence [63]. The combination of rtfMRI-EEG BCI systems are used for finding the depression [64], and emotion recognition [65] of patients can also be identified using fMRI BCI system. The BrainArena [66] connects two brains to a football video game using BCIs, and can score by thinking left and right movements. ...
... Urban food gardens such as rooftop farms not only transform unused open spaces into vibrant natural ones, but also offer diverse socio-environmental benefits such as short supply chains and low carbon emissions, in addition to obtaining food production sites closer to consumers [20]. Various sustainable approaches to water-and energy-saving practices have been developed and evaluated to explore how green roof systems can be utilized to mitigate climate change effects [23], and how vegetables could be grown and consumed in situ to facilitate food self-sufficiency for a city [24,25]. ...
... Between these seven sensors the water flow in and out of the modules can be obtained, isolating ET as differences in mass transfer. The data from the load cells were obtained by a Pi Zero microcomputer, combined with an 8-channel multiplexer to provide communication for all cells on the same i2c bus [40]. To mitigate the risks of water damage, all electronics were contained within a PVC conduit assembly. ...
... Incandescent grow lights Emission of light from heating Less efficient for plant growth due to intrinsic physic of blackbody radiation Massive amount of heat production can be harmful to plants Distance between incandescent grow lights and plants should not be less than 24 inches to avoid damages Marcos and Mai (2020) Halogen grow lights Emission of light from heating High luminosity and better colour in contrast to incandescent grow lights High temperature of the halogen grow lights can be harmful to plants Halogen grow lights produce light of red spectrum and very less from blue spectrum Mills and Dunn (2016) Fluorescent grow lights They are significantly efficient for plant growth as they produce light of in the range of visible spectrum They can be utilized for the growth of various plant species Efficiency of fluorescent grow lights decrease with time making them less suitable for controlled environment agriculture Cammarisano et al. (2021) High Pressure Sodium grow lights These are high-intensity discharge lamps Blue and orange lights are produced essential for growth of various plant species Massive generation of heat and poor CRI Gomez et al. (2013) Metal halide grow lights These lights provide UV light of all types, UVA,UVB, and UVC bands Less efficient than LED lights High capital cost and expansive handling Produces more heat than LED Gupta et al. (2017) Induction grow lights These lights interfere with Wi-Fi functionality due to magnetic induction Poor light penetration, poor efficiency, and high cost Kreuger et al. (2018) LED grow lights LED can produce lights of desired spectrum from blue-red spectrum LED light spectrum supports a wide range of plants species for growth Minimum heat generation and heat produced can be utilized for maintaining temperature in indoor farming LED light sources are extremely efficient, environment friendly, and can be used continuously Zareie et al. (2020) stilbene compound synthesis (Ahn et al., 2015a, b). There is an increase in stilbene production as well as the expression of 16 defense-related genes when plant products are exposed to various LEDs. ...
