Various fields have widely used place emotion extracted from social networking sites (SNS) information in recent years. However, the emotional information may contain biases as users are a particular subset of the whole population. This research studies whether there are significant differences between place emotion extracted from SNS and the place...

Neither Cadmium (Cd) nor lead (Pb) is necessary for crop growth, and they both cause severe soil pollution in many developing countries. A cross‐stress experiment was designed to investigate the feasibility of diagnosing the type and the level of Cd‐Pb cross stress by observing rice canopy hyperspectral images. Two‐way analysis of variance (ANOVA2)...

The advanced technologies in location-based services and telecom have yield large volumes of trajectory data. Understanding these data effectively requires intuitive yet accurate visual analysis. The visual analysis of massive trajectory data is challenged by the numerous interactions among different locations, which cause massive clutter. This pap...

It is generally feasible to classify different species of vegetation based on remotely sensed images, but identification of different sub-species or even cultivars is uncommon. Tea trees ( Camellia sinensis L.) have been proven to show great differences in taste and quality between cultivars. We hypothesize that hyperspectral remote sensing would m...

Some biochemical compounds are closely related with the quality of tea (Camellia sinensis (L.)). In this study, the concentration of these compounds including total tea polyphenols, free amino acids and soluble sugars were estimated using reflectance spectroscopy at three different levels: powder, leaf and canopy, with partial least squares regress...

Tea (Camellia Sinensis (L.)) is an important economic crop and the market price of tea depends largely on its quality. This research aims to explore the potential of hyperspectral remote sensing on predicting the concentration of biochemical components, namely total tea polyphenols, as indicators of tea quality at canopy scale. Experiments were car...

Understanding behavioural thermoregulation and its consequences is a central topic in ecology. In this study, a spatial explicit model was developed to simulate the movement and thermal habitat use of lizards in a controlled environment. The model incorporates a lizard's transient body temperatures with a cellular automaton (CA) algorithm and links...

Article
The potential of reflectance spectroscopy to estimate the concentration of biochemical compounds related to tea (Camellia sinensis (L.)) quality (total tea polyphenols and free amino acids) is demonstrated. Partial least squares regression (PLSR) was performed to establish the relationship between reflectance and biochemicals for leaf powders as we...

A remote sensing approach is proposed in this paper for monitoring instantaneous underwater light climate in Dahuchi Lake, China. Water constituents that are optically significant to the lake water can be retrieved through this method based on an artificial neural network (ANN) algorithm with a satisfactory accuracy. In this study, the ANN was trai...

Lizards are an "excellent group of organisms" to examine the habitat and microhabitat use mainly because their ecology and physiology is well studied. Due to their behavioral body temperature regulation, the thermal environment is especially linked with their habitat use. In this study, for mapping and understanding lizard's distribution at microha...

In this study, we monitored the quality of fresh tea leaves as raw materials of tea products by hyperspectral technology, as a way to explore the potential of hyperspectral remote sensing to detect the taste-related chemical components with low concentration in living plants. At leaf scale, empirical models have been established to find the relatio...

... Metallic stress can also cause changes in photosynthetic pigments and leaf morphology (Ruffing et al., 2021). Consequently, researchers have begun using HSI to quantify Cd stress in crops like rice and miscanthus (Zhang et al., 2018;Feng et al., 2019;Zhang et al., 2021), but this technology has not yet been tested in leafy green crops, or to evaluate in the context of whether soil amendments can effectively bind Cd in soil. ...
... Some scholars use visual analysis methods such as edge bundling, OD point clustering to solve the phenomenon of overlapping and displaying confusion of edges [1,[4][5][6], thus highlighting the larger flow of OD clusters. Some scholars also use spatial clustering for pattern recognition by O-point clustering, D-point clustering, OD-point clustering, and OD flow (edge) clustering for different application scenarios [7][8][9][10][11]. In terms of research ideas and methods of OD flow clustering, most researchers regard OD flow data as a set of O and D points. ...
... Detection of amino acids and total polyphenols. Free amino acids were detected by ninhydrin colorimetry and read with spectrophotometer at 570 nm using L-theanine as standard curve, as described by Tu et al. 27 Total polyphenol content was detected by the Folin-Ciocalteu method as previously described 28 , and read with ultraviolet spectrophotometer (Yuan Xi Instrument Co., Ltd., Shanghai) at 765 nm. ...
... Using the selected sensitive band range, we constructed the PLSR model of each amino acid and performed the regression coefficient test of the model. When screening sensitive bands, we referred to the study by Meng et al. (2013). Taking the band reflectance of the two regions as input variables, the estimation models of amino acids in maize leaves were established based on PLS regression. ...
... The critical mediating factors influencing algal production are light attenuation, nutrient availability, and temperature (Davies et al., 2008). Light availability in aquatic systems is determined by waterbody morphology, turbidity and depth, as well as shading from aquatic and surrounding vegetation (Anthony et al., 2004;Liu et al., 2010). Turbidity due to suspended clays can be a particularly important limiting factor in Australian waters (Hamilton & Gehrke, 2005). ...
... Therefore, it is necessary to study the spatial features of tea to make up for the lack of information. To date, hyperspectral imaging technology has been used to improve the evaluation of tea components, including polyphenols [37][38][39], amino acid [40], and catechins [41], due to the advantages of simultaneous acquisition of spatial image information and spectral information of the analyte. However, it remains unclear whether it is possible to improve the estimation model of the polyphenol content of cross-category tea based on the fusion features of different sensors. ...
... Air temperature, substrate temperature, humidity, solar radiation, wind speed and availability of shade can be assessed as some of the most important environmental factors that influence the thermal activities of lizards (Fei et al., 2012a(Fei et al., , 2012bKiefer et al., 2007;Logan et al., 2015). In addition to abiotic factors in the environment, morphological and physical characteristics, such as coloration, can also influence the thermal biology of ectotherms (Clusella-Trullas and Chown, 2014;Sagonas et al., 2013a;Tanaka, 2005a,b). ...

... Reflectance spectroscopy was used to estimate the biochemical compound concentration (tea polyphenols and total amount of free amino acid) related to the mass of tea (Camellia sinensis (L.). Hyperspectral remote sensing is useful for lateral monitoring on chemical elements intea leaves [25]. As indicated in previous studies, an accurate and precise spectrum measure demonstrates the characteristics of the target material [26]. ...
