Environmental Events

Some issues of the use of unmanned aircraft and space vehicles in monitoring the consequences of technical and environmental events and precision farming are considered. The proposed technology is aimed at improving the recognition accuracy of infrastructure objects with obtaining the numerical values of their 3D coordinates. The aim of the research is to improve the quality of monitoring using neural network identification and classification of objects in multi-zone satellite images obtained from unmanned aerial vehicles (UAV). Research includes both theoretical research and applied problem solving. The mathematical basis of image processing is the image recognition computer. Practical research is based on experimentation, software implementation, testing of algorithms and technology. An effective method of video surveillance of the territory has been improved. The task of the authors' research is to improve the accuracy of objects recognition on the earth's surface (specific infrastructure objects, the sky, the state of vegetation of agricultural land). The authors have experience in this area. The solution to this problem occurs simultaneously in two directions. The first direction: the technical result is ensured by the fact that the technology offers the use of a UAV equipped with two video cameras. The second direction is the use of scientific idea consisting in the development of a method for joint computer processing of digital and analog images obtained from UAVs, as well as quasi-simultaneous and reusable multi-zone satellite images. A new result of the research is the developed data structure for storing the model of the recognition process, which allows to jointly save dissimilar characteristics and membership functions of different types in the same tables

<p><em>As we know, Indonesia has a dynamic structure of the earth's surface layer. This topographic differences level was results in land variations and it  impacts on the material contained in it. This certainly will growth an enrich amount of natural land resources and the quality of plant vegetation and the sea. All of them are natural resources that are beneficial for human survival and the other habitats.</em> <em>To monitoring its management from the surface, we need a method that serves to inform the potential region conditions, one of them is the Geospatial Information System (GIS). Generally, taken data for GIS could be obtained through aerial photography of satellite images. However, the results are less accurate, so that, we look for the other alternatif instruments, which could made a GIS map better, using the design of unmanned aircraft  vehicle (PTTA) or commonly known as drones. For now, Unmanmed Aircraft Vehicle is  a currently  technology which that is growing rapidly. On this occasion, the author will introduce UAV technology that can be designed by itself according to needed, and could be able to answer every problems in which related to image mapping from geospatial information systems.</em></p><p> </p>

Banyuwangi Regency is one of the agricultural centers in East Java province and Indonesia. Mostly,Banyuwangi people work as farmers due to the fertil soil and wide amount of agricultural land in Banyuwangi . Thelarge number of people who work as farmers initiating the formation of farmer groups. One of the farmer groups in theSrono sub-district of Banyuwangi is the "Tan Selo 1" farmers group located in the village of Sukomaju and the "TanSelo 2" farmers group in Sukonatar village. The normal average price of one banana bunch in Banyuwangi is between50-60 thousand depending on the type and quality of bananas. Problems arise when the quantity of bananas in the marketarose, the price of 1 bunch of bananas decreases dramatically. The price of 1 bunch which is usually set at 50-60thousand drops drastically to only 20-30 thousand. This is certainly a problem for farmers in the Tan Selo group. The lackof knowledge of Tan Selo farmers about alternative variants of processed banana based products and the lack ofknowledge of the marketing strategies make it hard for the Tan Selo farmers to increase the economic value of bananaswhich have been used as an alternative income for farmers. Therefore, the solutions offered to overcome the problems offarmers include: equipping and improving farmers' knowledge about the variety of processed banana-based foods andtheir marketing strategies, conducting training to make variations on banana-based foods, conducting training oneffective marketing strategies. Overall, a series of community service programs were carried out perfectly as it expected.The percentage of participants' understanding in choosing high quality bananas is 85%, the percentage of participants’ability in processing banana-based foods is 86%, and percentage of participants who successfully sell processed foodproducts by utilizing online shopping sites is 70%

The spatiotemporal fusion technique has the advantages of generating time-series images with high-spatial and high-temporal resolution from coarse-resolution to fine-resolution images. A hybrid fusion method that integrates image blending (i.e., spatial and temporal adaptive reflectance fusion model, STARFM) and super-resolution (i.e., very deep super resolution, VDSR) techniques for the spatiotemporal fusion of 8 m Formosat-2 and 30 m Landsat-8 satellite images is proposed. Two different fusion approaches, namely Blend-then-Super-Resolution and Super-Resolution (SR)-then-Blend, were developed to improve the results of spatiotemporal fusion. The SR-then-Blend approach performs SR before image blending. The SR refines the image resampling stage on generating the same pixel-size of coarse- and fine-resolution images. The Blend-then-SR approach is aimed at refining the spatial details after image blending. Several quality indices were used to analyze the quality of the different fusion approaches. Experimental results showed that the performance of the hybrid method is slightly better than the traditional approach. Images obtained using SR-then-Blend are more similar to the real observed images compared with images acquired using Blend-then-SR. The overall mean bias of SR-then-Blend was 4% lower than Blend-then-SR, and nearly 3% improvement for overall standard deviation in SR-B. The VDSR technique reduces the systematic deviation in spectral band between Formosat-2 and Landsat-8 satellite images. The integration of STARFM and the VDSR model is useful for improving the quality of spatiotemporal fusion.

This paper presents the results of pedological and phytocoenological research focused on the detailed research of chemical parameters (pH, organic carbon, and nutrients), risk elements (As-metalloid, Cd, Co, Cr, Cu, Ni, Pb, and Zn), and species composition of the vegetation of two different peatlands on the territory of Slovakia—Belianske Lúky (a fen) and Rudné (a bog). Sampling points were selected to characterize the profile of the organosol within the peatland, the soil profile between the peatland and the agricultural land, and the soil profile of the outlying agricultural land, which is used as permanent grassland. Based on phytocoenological records, a semi-quantitative analysis of taxa in accordance with the Braun–Blanquet scale was performed. The study revealed that the thickness of the peat horizon of the fen in comparison with the bog is very low. In terms of the quality of organic matter, the monitored peatlands are dominated by fresh plant residues such as cellulose and lignin. Differences between individual types of peatlands were also found in the soil reaction and the supply of nitrogen to the organic matter of peat. The values of the soil exchange reaction were neutral on the fen, as well as slightly alkaline but extremely low on the bog. A significantly higher nitrogen supply was found in the organic matter of the fen in contrast to the bog. At the same time, extremely low content of accessible P and an above-limit content of As in the surface horizons were also found on the fen. From the phytocoenological point of view, 22 plant species were identified on the fen, while only five species were identified on the bog, which also affected the higher diversity (H’) and equitability (e). The results of the statistical testing confirmed the diversity of the studied peatlands and the different impact of environmental variables on plant diversity.

Abstract The near chora (agricultural land) of Tauric Chersonesos was investigated using multiyear remote sensing data and field surveys. The boundaries of the land plots were studied with GIS (Geographic Information Systems) technology and an analysis of satellite images. Reliable reconstruction of the borders has been done for 231 plots (from a total of about 380), which is approximately 53% of the Chersonesean chora. During the last 50 years, most of the ancient land plots have been destroyed by modern buildings, roads, or forests. However, in the 1960s, a significant part of the chora was still preserved. Changes in preservation with time were studied with the aid of satellite images that were made in 1966 and 2015. During that period, it was found that the number of plots with almost-complete preservation decreased from 47 to 0. Those land plots whose preservation was better than 50% dropped from 104 to 4. A temporal map shows this decline in preservation. It was found that the areas of land plots could be determined accurately with satellite images; compared to field surveys, this accuracy was about 99%.

AbstractThe medical practice of declawing has received much political debate over the past few years. Yet, empirical and theoretical research on how this practice is maintained and the ethical positions of those who actually participate in this work is lacking. Drawing from 9 months of ethnographic fieldwork in a feline-specific veterinary hospital and open-ended interviews with veterinarians and staff, this study examines veterinary staff members' attitudes toward, and strategies for, dealing with the medical practice of declawing. Specifically, findings show that a number of staff felt uncomfortable with their participation in onychectomy (declawing) and relied heavily on organizational support structures to cope both with these feelings and the moral ambiguity about the practice. Relying on these structures, the veterinarians and their staff are able simultaneously to define felines as subjects worthy of respect for their quality of life, protect their own self-identity as people who work toward the best interest of animals, and paradoxically support action toward felines that they find morally objectionable.

Compared to traditional EDM processing, UEDM (Ultrasonic Vibration Assisted EDM) have a great improvement in optimizing discharge environment. In this study, ultrasonic vibration is attached to the electrode. According to the relative positional relationship between the movement path of the electrode tip and the discharge gap, four working states of UEDM are defined. The four working states are the path within the discharge gap, the path in contact with the edge of the discharge gap, part of the electrode end path outside the discharge gap, and the path in contact with the workpiece, respectively. States are analyzed from the effective discharge energy and discharge frequency. A mathematical model for effective discharge energy and surface roughness is established for two conventional working states. The correctness of the theoretical research is verified by experiments. As the experiment results shown, the influence of ultrasonic amplitude on the energy of UEDM is primary, while frequency is secondary. A working state with better discharge stability and higher discharge energy when the electrode end path is in contact with the edge of the discharge gap. In the first three conventional machining states, the surface quality of the workpiece increases with the increase of ultrasonic amplitude and frequency. The study can provide scientific guidance for parameter matching of UEDM.

This paper presents a theoretical research on electronic resources provided for mathematics education in primary school including online education, which has become ubiquitous as a result of the COVID-19 pandemic. Various aspects and forms of application of e-resources in mathematics education are explored in the literature, but the issue of their quality is less studied. E-resources potential to dynamically illustrate the mathematical learning content is defined as their main advantage, but this potential could be realized only in compliance with the principles of multimedia, as well as the requirements for accessibility, ergonomics and visual design. Therefore, in this study the parameters for the quality of e-resources for mathematics education in primary school are derived and specific criteria and requirements for their quality are proposed. Thus, in addition to providing a basis for future research, this paper could serve to primary teachers as a guide for measuring the quality of e-resources that they select or create for online mathematics education.
