Hitherto, the intelligent detection of black tea fermentation quality is still a thought-provoking problem because one-side sample information and poor model performance. This study proposed novel method for prediction major chemical components including total catechins, soluble sugar caffeine using hyperspectral imaging technology electrical properties. The multielement fusion were used to establish quantitative models. performance was better than that single information. Subsequently,...
A multi-parameters monitoring system based on wireless network was set up to achieve remote real-time of aquaculture water quality, in order improve the quality products and solve such problems as being difficult wiring high costs current system. In solar cells lithium were used for power supply. The YCS-2000 dissolved oxygen sensor, pH electrode, Pt1000 temperature sensor ammonia nitrogen monitor parameters quality; STM32F103 chip data processing; Zigbee GPRS modules transmission center,...
The determination of heavy metals in soils is great significance for the monitoring and control environmental pollution.
Potassium in soil is an essential nutrient for plants.
The consumption of pears has increased, thanks not only to their delicious and juicy flavor, but also rich nutritional value. Traditional methods detecting internal qualities (e.g., soluble solid content (SSC), titratable acidity (TA), taste index (TI)) are reliable, they destructive, time-consuming, polluting. It is necessary detect rapidly nondestructively by using near-infrared (NIR) spectroscopy. In this study, we used a self-made NIR spectrum detector with an improved variable selection...
Abstract Lignin plays an important role in the formation of stone cells pears. However, accumulation lignin had adverse impact on flavor and quality fruit. A rapid accurate method for measuring content pears is therefore required. An improved variables selection called ‘the bootstrapping soft shrinkage combined with frequency regression coefficient (FRCBOSS)’ was developed based (BOSS)’technique, to identify characteristic wavelengths near‐infrared (NIR) spectra non‐destructive analysis...
Most studies only focus on the sex discrimination of silkworm pupae. However, species differentiation pupae is also needed in sericulture. To classify and at same time, present study adopts near infrared (NIR) spectroscopy combined with multivariate analysis.First, spectra samples were acquired using an NIR sensor, comprising female male from three species. Second, different variables selection approaches used, including a successive projections algorithm, competitive adaptive reweighted...
This paper proposes a novel finger-individuating exoskeleton system with non-contact leader-follower control strategy that effectively combines motion functionality and individual adaptability. Our solution comprises the following two interactive components: leader side follower side. The processes joint angle information from healthy hand during via Leap Motion Controller as input, providing more flexible active operations owing to manner. Then, side, is driven assist user's for...
The thick rind of Fukumoto navel orange is a great barrier to light penetration, which makes it difficult evaluate the internal quality accurately by visible-near-infrared (Vis-NIR) transmittance spectroscopy. information carried transmission spectrum limited. Thus, application genetic algorithm (GA) for variable selection may not reach expected results, and selected variables contain redundancy. In this paper, we present use discrete wavelet transforms optimizing GA-partial least squares...
Abstract Snow pears are an important and widespread agricultural product that can relieve respiratory symptoms, constipation, alcoholism. Lignin content (LC) has a direct negative role on the fruit texture taste of snow pears. Here, we studied effect near‐infrared (NIR) spectroscopy determination LC in due to position at which spectral measurements were obtained. NIR diffuse reflection spectra collected from nine measurement positions each sample by portable spectrometer. Partial least...
Rapid and sensitive detection of mercury vapor is great significance for environmental protection human health. But the method enabling low limitation rapid response at room temperature simultaneously has rarely been reported. In this work, we propose a gold particles decorated reduced graphene oxide sensor detection. After adding particles, sensors' sensitivity increase by more than 16 times time significantly decreases, which far less below results reported others. The performance...
China’s agricultural facilities are developing rapidly and mainly operated through household contracting. Due to a lack of suitable variable-rate fertilization devices, manual blind still widely exists, resulting in fertilizer waste environmental pollution. Meanwhile, existing devices cannot simultaneously meet the needs different methods for crop cultivation, increasing cost mechanized fertilization. This study developed lightweight dual-mode automatic device control system strip spreading...
In near-infrared spectroscopy applications, the original spectra often contain redundant information, which will seriously affect performance of chemometric models. Therefore, preprocessing, effective wavelengths selection, and appropriate regression models are essential. The objective this study was to optimize nondestructive determination multivariate calibration model sugar content in 'Snow' pears, using diffuse reflectance combined with chemometrics. All data (sugar reference values...
