The Solar Energy Harvester and UNet Segmentation with CNN-Based MPPT Algorithm in Efficient Photovoltaic Unit (SEUCMP) combines PV design with advanced deep learning methodologies to enhance energy management. It aims to configure solar arrays to produce 11 kW daily, optimizing the arrangement of modules for maximum efficiency. A UNet-based segmentation framework improves predictive accuracy by analyzing images of solar plants. The system utilizes a distinctive Energy Monitor (EM) circuit for regulation, where minimal capacitance is designed to reduce future dependence on software promotional techniques. At the MPPT level, a hybrid LSTM-FNN strategy is employed to optimize energy forecasting, addressing the variability in solar conditions through the Cuckoo Search Optimizer (CSO). Using the following parameters, we calculated the SEUCMP model, power analysis, mean square error, loss & accuracy, and mean IOU calculations.

Composite coatings containing iodine- and bromine-containing compounds as biocides have been obtained on the basis of industrial paintwork materials. A number of composite coatings containing biocides – Nitroxynil, Ioxynil and 2,5-dibrom-4-nitrophenol, have been analyzed using a modified technique for assessing biological activity and toxicity for determining the survival rate of Artemia salina crustaceans. It was found that the compositions on the basis of paintwork materials with Nitroxynil show the greatest bioactivity. AFM study of the surface morphology of the developed coatings showed that the introduction of biocides leads to coating structuring at the nanolevel, with the strength of nanostructured coatings on impact decreases by 2–3 times, however, these values are 2 times higher than those of the reference sample – an industrial copper-containing antifouling paint. The obtained results can be used for further development of environmentally safe protective and antifouling polymer coatings and paintwork materials.

This study seeks to identify housing design needs among elderly couple households by examining how empty nesters suffer from an incompatibility between their daily activities and the dwelling space in their condominiums and by tracing how they adjust their space use over time. To this end, an online survey was conducted with the target households classified according to the number of years that had elapsed since their children had left home. The survey findings demonstrate the formation of personal territories by both spouses in parallel with their keen appreciation of the shared use of common dwelling spaces including living room.

Spatial comprehension exercise system with Three-Dimensional Computer Graphics: 3D CG of toy model for disabled children is proposed. In order to improve spatial comprehension in an attractive manner, a toy model is created together with building block model. Through experiments, it is confirmed that the spatial comprehension is improved for the disabled children remarkably.

The aroma components in secondarily formulated flavor blocks of different storage durations were analyzed by solvent extraction combining with GC/MS.The changes of these components were evaluated by principal component analysis and t-test.The results showed that the aroma components in the samples could be satisfactorily extracted by dichloride methane with good repeatability.The results of GC/MS analytical data processed by principal component analysis and t-test reflected the variation of the samples as a whole and significance of changes of individual aroma component during storage,which provided reference for the evaluation of the stability and storage duration of secondarily formulated flavor blocks.

We investigated the antioxidant capacity and peroxy radical scavenging activity of raw mantle tissue extract of the swordtip squid Loligo edulis at various freshness levels using the chemiluminescence method. The antioxidant capacity of the extract was highest at K value, which is an index for freshness of fish and shellfish, of 20–40% (P < 0.05). The antioxidant capacity decreased at K values of above 40%, and there were no significant difference among K value 40–60%, 60–80% and above 80% (P < 0.05). Among the ATP-related compounds in the extracts, the main compounds were AMP and hypoxanthine. The correlation between antioxidant capacity and the amount of hypoxanthine was high especially at K value of above 80%. However, the participation of ATP-related compounds in the total antioxidant capacity was low, though they have some antioxidant capacities. Present study is the first report to show the participation of ATP-related compounds on the antioxidant capacity of squid with deterioration. PRACTICAL APPLICATIONS ATP-related compounds, which are included in fish and shellfish, are constituent factors of K value, which is important for a freshness index. We inspected the possibility of ATP-related compounds for the participation to antioxidant capacity that is one of important functions of the food. The result of this study newly showed the superiority of good freshness by clarifying that fresh squid has a higher antioxidant capacity. Freshness optimized both palatability and food hygiene. The participation of ATP-related compounds in the total antioxidant capacity was low. However, the contribution ratio was gradually increased. This result gave us the opportunity to inspect the participation of the ATP-related compounds to the antioxidant capacity in the other foods.

The content of chlorine in tobacco determined by continuous flow analysis (CFA), the standard method described in YC/T 162-2002 and GB 13580.9-1992, is considerably different from that by other classical methods, such as Moore method, potentiometric titration and ion chromatography. Therefore, the various factors affecting CFA were investigated, optimized and improved: 1) a dialyzer was set in the analyzer; 2) the detecting wavelength was shifted from 480 nm to 490 nm; 3) the flow-through cell with 15 mm optical path was replaced by a 10 mm flow-through cell without bubble elimination; 4) the determined optimum coloring reaction time was about 665 seconds; 5) the flow scheme of instrument was redesigned. The results showed that: the disturbance from the background color of tobacco extract was eliminated; the detection period reduced from 160 seconds to 90 seconds; the content of chlorine in tobacco determined by the improved method was highly in accordance with that by the classical methods mentioned above, with RSD5% and t = 1.6278t1-a=0.10/2(n-1)=1.7341. The improved method is fit for fast analysis of chlorine in tobacco.
