Mapping Plastic Greenhouses with Two-Temporal Sentinel-2 Images and 1D-CNN Deep Learning
Authors: Sun Haoran , Wang Lei , Lin Rencai , Zhang Zhen , Zhang Baozhong
Published: July 2021

Plastic greenhouses (PGs) are widely built near cities in China to produce vegetables and fruits. In order to promote sustainable agriculture, rural landscape construction, and better manage water resources, numerous remote sensing methods have been developed to identify and monitor the distribution of PGs, of which many map PGs based on spectral responses and geometric shapes. In this study, we proposed a new fine- and coarse-scale mapping approach using two-temporal Sentinel-2 images with various seasonal characteristics and a one-dimensional convolutional neural network (1D-CNN). Having applied this approach in a pilot area study, the results were summarized as follows: (1) A time-series analysis of Sentinel-2 images showed that the reflectance of greenhouses changes during crop growth and development. In particular, the red-edge and near-infrared bands undergo a significant increase and then decrease during the whole crop growth period. Thus, two critical period images, containing a substantial difference in greenhouse reflectance, were sufficient to carry out an accurate and efficient mapping result. (2) The 1D-CNN classifier was used to map greenhouses by capturing subtle details and the overall trend of the spectrum curve. Overall, our approach showed higher classification accuracy than other approaches using support vector machines (SVM) or random forests (RF). In addition, the greenhouse area identified was highly consistent with the existing surfaces observed in very high-resolution images, with a kappa co-efficient of 0.81. (3) The narrow band feature differences (red-edge and near infrared narrow bands) in two-temporal Sentinel-2 images played a significant role in high-precision greenhouse mapping. The classification accuracy with narrow band features was much better than the maps produced without narrow band features. This scheme provided a method to digitize greenhouse precisely and publish its statistics for free, which enable advanced decision support for agriculture management.

Authors: Lin Zhe , Guo Wenxuan
Published: July 2021

An accurate stand count is a prerequisite to determining the emergence rate, assessing seedling vigor, and facilitating site-specific management for optimal crop production. Traditional manual counting methods in stand assessment are labor intensive and time consuming for large-scale breeding programs or production field operations. This study aimed to apply two deep learning models, the MobileNet and CenterNet, to detect and count cotton plants at the seedling stage with unmanned aerial system (UAS) images. These models were trained with two datasets containing 400 and 900 images with variations in plant size and soil background brightness. The performance of these models was assessed with two testing datasets of different dimensions, testing dataset 1 with 300 by 400 pixels and testing dataset 2 with 250 by 1200 pixels. The model validation results showed that the mean average precision (mAP) and average recall (AR) were 79% and 73% for the CenterNet model, and 86% and 72% for the MobileNet model with 900 training images. The accuracy of cotton plant detection and counting was higher with testing dataset 1 for both CenterNet and MobileNet models. The results showed that the CenterNet model had a better overall performance for cotton plant detection and counting with 900 training images. The results also indicated that more training images are required when applying object detection models on images with different dimensions from training datasets. The mean absolute percentage error (MAPE), coefficient of determination (R2), and the root mean squared error (RMSE) values of the cotton plant counting were 0.07%, 0.98 and 0.37, respectively, with testing dataset 1 for the CenterNet model with 900 training images. Both MobileNet and CenterNet models have the potential to accurately and timely detect and count cotton plants based on high-resolution UAS images at the seedling stage. This study provides valuable information for selecting the right deep learning tools and the appropriate number of training images for object detection projects in agricultural applications.
Comparison of Modelling Strategies to Estimate Phenotypic Values from an Unmanned Aerial Vehicle with Spectral and Temporal Vegetation Indexes
Authors: Hu Pengcheng , Chapman Scott C. , Jin Huidong , Guo Yan , Zheng Bangyou
Published: July 2021

Aboveground dry weight (AGDW) and leaf area index (LAI) are indicators of crop growth status and grain yield as affected by interactions of genotype, environment, and management. Unmanned aerial vehicle (UAV) based remote sensing provides cost-effective and non-destructive methods for the high-throughput phenotyping of crop traits (e.g., AGDW and LAI) through the integration of UAV-derived vegetation indexes (VIs) with statistical models. However, the effects of different modelling strategies that use different dataset compositions of explanatory variables (i.e., combinations of sources and temporal combinations of the VI datasets) on estimates of AGDW and LAI have rarely been evaluated. In this study, we evaluated the effects of three sources of VIs (visible, spectral, and combined) and three types of temporal combinations of the VI datasets (mono-, multi-, and full-temporal) on estimates of AGDW and LAI. The VIs were derived from visible (RGB) and multi-spectral imageries, which were acquired by a UAV-based platform over a wheat trial at five sampling dates before flowering. Partial least squares regression models were built with different modelling strategies to estimate AGDW and LAI at each prediction date. The results showed that models built with the three sources of mono-temporal VIs obtained similar performances for estimating AGDW (RRMSE = 11.86% to 15.80% for visible, 10.25% to 16.70% for spectral, and 10.25% to 16.70% for combined VIs) and LAI (RRMSE = 13.30% to 22.56% for visible, 12.04% to 22.85% for spectral, and 13.45% to 22.85% for combined VIs) across prediction dates. Mono-temporal models built with visible VIs outperformed the other two sources of VIs in general. Models built with mono-temporal VIs generally obtained better estimates than models with multi- and full-temporal VIs. The results suggested that the use of UAV-derived visible VIs can be an alternative to multi-spectral VIs for high-throughput and in-season estimates of AGDW and LAI. The combination of modelling strategies that used mono-temporal datasets and a self-calibration method demonstrated the potential for in-season estimates of AGDW and LAI (RRMSE normally less than 15%) in breeding or agronomy trials.
A Spliced Satellite Optical Camera Geometric Calibration Method Based on Inter-Chip Geometry Constraints

Published: July 2021

When in orbit, spliced satellite optical cameras are affected by various factors that degrade the actual image stitching precision and the accuracy of their data products. This is a major bottleneck in the current remote sensing technology. Previous geometric calibration research has mostly focused on stitched satellite images and has largely ignored the inter-chip relationship among original multi-chip images, resulting in accuracy loss in geometric calibration and subsequent image products. Therefore, in this paper, a novel geometric calibration method is proposed for spliced satellite optical cameras. The integral geometric calibration model was developed on inter-chip geometry constraints among multi-chip images, including the corresponding external and internal calibration models. The proposed approach improves uncontrolled geopositioning accuracy and enhances mosaic precision at the same time. For evaluation, images from the optical butting satellite ZiYuan-3 (ZY-3) and mechanical interleaving satellite Tianhui-1 (TH-1) were used for the experiments. Multiple sets of satellite data of the Songshan Calibration field and other regions were used to evaluate the reliability, stability, and applicability of the calibration parameters. The experiment results found that the proposed method obtains reliable camera alignment angles and interior calibration parameters and generates high-precision seamless mosaic images. The calibration scheme is not only suitable for mechanical interleaving cameras with large geometric displacement among multi-chip images but is also effective for optical butting cameras with minor chip offset. It also significantly improves uncontrolled geopositioning accuracy for both types of spliced satellite images. Moreover, the proposed calibration procedure results in multi-chip satellite images being seamlessly stitched together and mosaic errors within one pixel.

Coronavirus Disease 2019 (COVID-19) has challenged the health system worldwide, including the low and middle income countries like Nepal. In view of the rising number of infections and prediction of multiple waves of this disease, mortalities due to COVID-19 need to be critically analyzed so that every possible effort could be made to prevent COVID-19 related mortalities in future. Main aim of this research was to study about the mortalities due to COVID-19 at a tertiary level hospital, in Nepal. This was a retrospective, observational study that included all inpatients from Sukraraj Tropical and Infectious Disease Hospital, who were reverse transcriptase polymerase chain reaction positive for SARS-COV-2 and died during hospital stay from January 2020 till January 2021. Medical records of the patients were evaluated. Out of 860 total admissions in a year, there were 50 mortalities in the study center. Out of 50 mortalities, majority were males (76%) with male to female ratio of 3.17:1. Most were above 65 years of age (72%) and had two or more comorbidities (64%). The most common comorbidities among the patients who had died during hospital stay were hypertension (58%) followed by diabetes mellitus (50%) and chronic obstructive airway disease (24%). The median duration from the symptom onset to death was 18 days, ranged from the minimum of 2 days till maximum of 39 days. D-dimer was found to be >1 mg/L in 58% cases and ferritin was >500 ng/ml in 42% patients at presentation. A total of 42% patients had thrombocytopenia, 80% patients had lymphocytopenia and 60% had Neutrophil to Lymphocyte ratio >11.75 with the mean NLR of 18.38. Of total mortalities, 16% patients also showed microbiological evidence of secondary infection; Male gender, age more than 65 years, multiple comorbidities with lymphocytopenia, elevated Neutrophil lymphocyte ratio and elevated inflammatory markers were risk factors found in majority of mortalities in our study. These findings could be utilized for early triage and risk assessment in COVID-19 patients so that aggressive treatment strategies could be employed at the earliest to reduce mortalities due to COVID-19 in future.
Karst Recharge Areas Identified by Combined Application of Isotopes and Hydrogeological Budget
Authors: Iacurto Silvia , Grelle Gerardo , De Filippi Francesco Maria , Sappa Giuseppe
Published: July 2021

The identification of recharge areas in karst aquifers allows us to perform sustainable management of these groundwater resources. Stable isotopes (δ18O and δ2H) have been largely used to provide information about recharge elevation in many mountainous regions. In this paper, an improved version of a recent “isotope-driven model”, for the identification of recharge areas, was applied to Capodacqua di Spigno Spring (south of the Latium region). The model upgrade consists of a preliminary check procedure to estimate the degree of influence of the rainfall’s isotopic variability on the spring water. This additional procedure gives us an indication of the reliability of the model and its applicability conditions. Moreover, the dataset of the spring was updated to analyze the degree of reliability of the isotope-driven model. The purpose of this study was to combine the previously mentioned isotope-driven model with hydrogeological tools. A quantitative study of the basin, based on the estimation of the average monthly infiltration volume, was performed by using the inverse hydrogeological water budget. In this way, the qualitative model for the recharge areas’ estimation was validated by a quantitative hydrogeological tool. Both models show that, for karst mountain basins, the recharge areas decrease as the average recharge elevations increase, including areas at high altitudes.
The Management of Na-Tech Risk Using Bayesian Network
Authors: Ancione Giuseppa , Milazzo Maria Francesca
Published: July 2021

In the last decades, the frequency and severity of Natural-Technological events (i.e., industrial accidents triggered by natural phenomena or Na-Techs) increased. These could be more severe than simple technological accidents because the natural phenomenon could cause the prevention/mitigation/emergency systems fail. The dynamic assessment of the risk associated with these events is essential for a more effective prevention and mitigation of the consequences and emergency preparation. The main goal of this study is the development of a fast and dynamic tool for the risk manager. An approach supporting the management of the consequence is presented. It is based on the definition of a risk-related index, presented in the form of a discrete variable that combines frequency and magnitude of the events and other factors contributing to the worsening of Na-Tech. A properly designed Geographical Information System (GIS) allows the collection and processing of territorial information with the aim to create new data contributing to the quantification of the Na-Tech risk index. A Bayesian network has been built which efficiently lends in including within the model multiple elements with a direct or indirect impact on the distribution of risk levels. By means of this approach, a dynamic updating of the risk index is made. The proposed approach has been applied to an Italian case-study.
Temperature Changes and Their Impact on Drought Conditions in Winter and Spring in the Vistula Basin
Authors: Karamuz Emilia , Romanowicz Renata J.
Published: July 2021

Inter-annual variability of hydro-meteorological variables indirectly influence soil moisture conditions in winter and early spring seasons. The interactions between temperature changes and drought conditions are studied by an application of statistical analyses of minimum temperature (Tmin), consecutive days with temperature exceeding the 0 °C threshold value, the number of melting pulses in the winter season and Standardized Evaporation Precipitation Index (SPEI). Additionally, shifts in the onset of days with spring temperature and snow cover occurrence are analysed. A Mann–Kendall test is applied for the trend analysis. Studies have shown significant changes in thermal characteristics in the winter season over the past 70 years, which affect the moisture conditions in the Vistula River Basin. As a result of those changes, the Vistula Basin is more prone to droughts.

O Brasil é constituído por uma multiculturalidade vinculada a um complexo processo de miscigenação de povos originários e migrantes de diversos continentes, entre os quais estão os grupos étnicos provindos da África, cujos descendentes compõem uma grande parcela da população. Em reconhecimento ao expressivo contingente e pelas circunstâncias históricas de exploração e degradação por que passam afrodescendentes ao longo de séculos, o Brasil reconheceu e implantou a Educação Quilombola. Neste artigo são discutidos aspectos de uma pesquisa realizada com estudantes do 9º ano do Ensino Fundamental de uma escola quilombola de Pernambuco. O estudo teve como objetivos analisar como a aprendizagem da disciplina de Matemática interessa a estudantes quilombolas; refletir sobre como estudantes quilombolas concebem a importância de aprender Matemática na escola e identificar, sob a perspectiva da Educação Matemática Crítica, como a Matemática está presente nos planos desses estudantes. No recorte teórico utilizado elegeu-se o conceito de foreground relacionado com as oportunidades sociais, políticas, econômicas e culturais de cada indivíduo e suas perspectivas futuras em relação à aprendizagem de Matemática. Os foregrounds possuem dimensões externas e subjetivas, sendo, a primeira, relacionada ao contexto em que o indivíduo está situado, e a segunda está ligada a maneira de como cada um percebe essa realidade em que está inserido, de forma libertadora ou limitadora. Sob esta perspectiva, o foreground pode se expandir e se moldar. O estudo teve um cunho qualitativo e os dados de pesquisa foram gerados por entrevistas e observações. As análises dos resultados indicaram que os participantes atribuem importância à identidade quilombola para a afirmação de suas origens, estabelecendo relações entre a Matemática e as situações da vida cotidiana. Neste sentido, a escola desempenha importante papel na formação dos foregrounds, favorecendo a formação positiva, sendo que os conteúdos e conhecimentos de Matemática têm importante papel nesse processo.

The article is devoted to the study of the strength and wear resistance of thread seams of membrane materials on a knitted basis. The characteristics of the composite membrane three-layer material are given and the modes of its stitching and the test method are substantiated. Investigations of material cutting through with a needle were carried out and the geometry of the sewing needle point was chosen. The results of the study of the strength of thread seams made along of the front layer of the material before and after modelling the operational tensile loads along and across the seam are presented. 15000 load-unload cycles were simulated, stretching the sample by 10 % of the seam length. As a result of a full factorial experiment, it was found that the linear density of the threads and the diameter of the needle have the greatest effect on the strength and wear resistance of the thread seams of the composite material. The influence of the sewing frequency is ambiguous for the parameter of the wear resistance of the seam when stretched along and across the line.

For this reason, a research is needed to optimize the inventory of Mazaya goods by computerization. The method used in this research is K-Means Clustering on sales data of Mazaya products. The data processed is the purchase, sales and remaining inventory of Mazaya products in March to July 2019 totaling 40 pieces. Data is grouped into 3 clusters, namely cluster 0 for non-selling criteria, cluster 1 for best-selling criteria and cluster 2 for very best-selling criteria. The test results obtained are cluster 0 with 13 data, cluster 1 with 25 data and cluster 2 with 2 data. So to optimize inventory is to multiply goods in cluster 2, so as to save costs for management of Mazayaproducts that are not available. K-Means clustering method can be used for data processing using data mining in grouping data according to criteria.

Varicella adalah salah satu penyakit yang mudah menyerang anak anak maupun orang dewasa ataupun ibu hamil. Varicella merupakan suatu gejala penyakit yang disebabkan oleh virus pada makanan dan lingkungan yang dapat diindikasi menjadi suatu penyakit yang akan diderita anak. Varicella dapat menyebar dengan mudah dari orang yang terinfeksi kesiapapun yang belum terkena cacar air sebelumnya dan belum mendapat vaksin cacar air. Di Indonesia penyakit varicella ini kurang menjadi perhatian masyarakat dikarenakan asumsi masyarakat yang menyatakan bahwa varicella akan sembuh sendiri. Oleh karena itu dirancang sebuah sistem pakar untuk mengetahui klasifikasi penyakit varicella pada anak. Metode yang digunakan dalam sistem pakar adalah Certainty Factor. Metode Certainty Factor menggunakan nilai kepastian untuk menguatkan hasil keputusan dari sistem pakar tersebut. Sistem pakar ini dapat memberikan solusi serta cara penanganan penyakit varicella pada anak dengan proses pendiagnosaan dilakukan secara efisien dan menghemat waktu dalam membantu masyarakat atau orang tua dalam pencegahan yang terjadi.

Sistem Monitoring Login Failure dengan Via Telegram dari Serangan Brutus pada Router Mikrotik
Authors: Dian Kurnia  , Juliandri
Published: July 2021

A monitoring system is needed to monitor a network topology from attacks that might occur at that time. A realtime monitoring system is needed to find out the attack. Therefore, in this study, an attack scenario on a proxy router was carried out using a brute force technique. The brute force technique is an efficient method that tries every possible login password character that the network administrator might use. This brute force technique already exists in the application used, namely Brutus. Brutus is executed by focusing the attack on port 23 telnet on the proxy router. The system log listed as a login failure caused by a brute attack on the proxy router will be forwarded by a script that is running to a notification with a network administrator telegram bot. From the results of research that has been carried out on the monitoring system on the proxy running in real time to notify the login failure message via telegram. The telegram notification will stop if the password has been found by Brutus or the Brutus dictionary does not find the password on the designed Mikrotik router network. Prevention is done by disabling open ports and activating the drop firewall menu if it finds a possible attacker's ip address on the mikrotik router to reduce attacks from the attacker.

La persona en la historia
Authors: Tullume Fenco Eliana , Cervera Vallejos Mirtha Flor
Published: July 2021

La persona a lo largo de la historia, es un breve ensayo que evidencia las revueltas y ataques hacia un solo concepto: Persona. De esta manera, el hombre se enfrenta a dos posiciones: De la filosofía tradicional y de las corrientes modernas; es decir, mientras que la filosofía necesita explorar aquellos conceptos poco ampliados sobre la persona, las corrientes aprovecharán estos vacíos para limitar al hombre a pensamientos, emociones y placeres, así como poner en tela de juicio su dignidad e integridad. En secuencia, a pesar de las diferentes perspectivas de estos movimientos, ambos concluyen que el hombre es un elemento indispensable en la sociedad. El descubrir la verdadera esencia humana, posibilita a encontrar el bien, la verdad y la belleza; asimismo reflexionar sobre la persona, también le permitirá alcanzar una extra conexión con el creador, quien a través del uso de las potencias plasma sus proyectos sobre cada uno.

Healthy condition is a parameter that is needed in life, one of the important parameters is the measurement of oxygen saturation in the blood and heart rate. The purpose of this research is to develop a Smartwatch SpO2 device and BPM sensor that is connected to WIFI using the Android Platform instead of using an LCD for parameter reading. This module design method uses the MAX30100 sensor to display the SpO2 and BPM values ​​displayed on the OLED. Data processing is carried out using ATMEGA 328P programming and then displayed in the Android-based Mit-app application. The results show the average error for the SPO2 value is 0.868 % and the standard deviation is 0.170 %, while the BPM value has an average error of 0.56 % and a standard deviation of 0.30%. From the results of the comparison data analysis, the largest error was 1.03% and the smallest was 0.62% for Spo2 ml/hour with an accuracy of 0.05 (0.57%) with a precision value of 0.08 at the selection speed of 50 ml/hour. From the results above, it can be concluded that the data can be displayed on OLED using the Mit-app Android application with an error rate accuracy of 0.57%.  From the results of this research design, it is hoped that it can facilitate the diagnosis of the condition of patients and health nurses
