The object of the study is a group of unmanned aerial vehicles (UAVs). The subject of the study is the decision-making process in management tasks using:
– an improved brown bear algorithm (BBA), which achieves the determination of the optimal UAV movement route based on the given optimization criterion (the probability of completing the flight task), described by complex multimodal functions;
– evolving artificial neural networks for deep learning of the multi-agent system knowledge base, by training both the parameters and the architecture of artificial neural networks.
The originality of the method lies in using additional improved procedures that allow:
– the initial BBA population and their initial position on the search plane are determined considering the degree of uncertainty in the data on the UAV group movement route;
– the initial speed of each BBA is considered, enabling the prioritization of searches in the respective search plane (height, latitude, and longitude);
– the suitability of the UAV group's flight route for performing the flight task is determined, considering a set of external factors, thereby reducing the decision search time;
– the universality of BBA food search strategies allows classifying a set of conditions and factors affecting the completion of the flight task.
This aids in identifying the most feasible movement options for the UAV group based on the defined optimization criterion for movement route. Modeling the operation of the proposed method has shown that the increase in decision-making efficiency reaches 15–18 %. The enhancement in the method's efficiency is achieved through additional procedures and ensuring the reliability of the decisions at a level of 0.9

The disinfection of air in premises, especially in the presence of people, is an important element of the system for the prevention of infectious diseases. A promising solution for this is to fill the premises with an antimicrobial chemical agent that would quickly neutralize pathogens directly at the moment they enter the air. It is advisable to use hypochlorous acid HOCl as such an agent. But traditional methods of administering HOCl into the air by aerosolizing its solutions may be accompanied by a number of risks that can be prevented by using gaseous HOCl. Therefore, it is relevant to develop evaporation devices that would take into account the specifics of chlorine-active compounds and determine the influence of various factors on the release of gaseous HOCl from them into the air being treated. During the study, a design of a device was developed in which the transfer of HOCl into the air is carried out by contact of the latter with a foamed working solution of sodium hypochlorite NaOCl. The HOCl concentration in the treated air mainly depends on its concentration in the working solution, which, in turn, is determined by the pH of the solution and the total content of free chlorine in it. Additionally, the influence of the air and working solution temperatures, the volume of the working solution, the power of air flows and other technological factors on the air HOCl concentration was studied. When using an electrochemically generated approx. 1000 mg/l NaOCl solution with pH 8.50–8.60 at 20 °C, it is possible to maintain the total chlorine concentration in the air flow with a capacity of 50 m3/h at a level of about 0.30 mg/m3 for a long time. Simple design, multifunctionality and the fundamental possibility of combining the processes of electrochemical synthesis of HOCl and its immediate administering into the air open up broad prospects for using the developed installations for continuous disinfection of premises

Abstract
The triple junction area, bordered by the Longmenshan, Xianshuihe, and Anninghe faults, is located at the southeastern corner of Songpan–Ganzi block, northern Tibet. In this area, a series of strong earthquakes occurred, including the 2008 Mw 7.9 Wenchuan, 2013 Mw 6.6 Lushan, 2014 Mw 5.9 Kangding, 2022 Mw 5.8 Lushan, and 2022 Mw 6.6 Luding. In addition, multiple hot springs with different temperatures are distributed along the faults in the same area. This study tries to figure out: (1) the necessity of catalog replenishment based on statistical method; (2) whether the special tectonic environment characterized by hot springs influences the evolution of aftershock sequences. A complete aftershock catalog is a fundamental data set for exploring these issues. However, the incompleteness of the catalog limits our understanding of aftershock evolution. Here, we applied a statistical catalog replenishment method to the five aftershock sequences, with the results showing that the replenishment method is helpful to improve the catalog completeness by producing more reasonable Omori law parameters. In addition, both the catalogs obtained from matched filter technique and the replenishment method have advantages and limitations, suggesting that combining two versions of catalog in aftershock evolution study is helpful. Finally, we revealed a negative correlation between the p-value of Omori law parameters and temperatures of hot springs, which may be useful to evaluate potential aftershock risks.

Published: December 2024

Abstrak. Maggot adalah organisme yang berasal dari telur lalat black soldier fly dan merupakan salah satu organisme pembusuk. Lalat ini berperan sebagai salah satu pilihan penyediaan pakan dengan sumber protein yang tinggi, mudah dikembang biakkan, dan mudah ditemukan. Kandungan protein dan lemaknya yang tinggi memungkinkan larva BSF untuk digunakan sebagai bahan baku bioindustri, karena protein yang dihasilkan lebih ekonomis, lebih ramah lingkungan, dan memiliki nilai konversi pakan yang tinggi. Budidaya maggot larva BSF merupakan salah satu alternatif budidaya ternak yang sedang berkembang, yang dapat digunakan sebagai pakan dan dekompuser untuk pengelolaan limbah organik. Budidaya maggot memiliki dampak positif dan negatif yang dipengaruhi oleh beberapa faktor. Salah satu metode yang digunakan untuk menganalisis dampak lingkungan adalah Life cycle assessment (LCA), yaitu metode yang menyederhanakan cara untuk melakukan penilaian potensi dampak lingkungan berkaitan dengan kegiatan produksi atau layanan jasa. Kegiatan budidaya maggot merupakan kegiatan yang menguntungkan, namun dipengaruhi oleh cara dan sumber daya yang digunakan. Oleh karena itu, perlu dilakukan analisis dampak dan pendapatan pada suatu usaha budidaya maggot.Analysis of Income in the Maggot Cultivation Business (Case Study of the Maggot Cultivation Business in the BSF Farm Meta Maggot Business, Lambisnis Village, Banda Aceh City)abstrack : Maggots are organisms that come from the eggs of the black soldier fly and are one of the decomposer organisms. This fly serves as one of the options for providing feed with a high protein source, easy to breed, and readily available. The high protein and fat content allows BSF larvae to be used as raw material in the bioindustry, as the protein produced is more economical, more environmentally friendly, and has a high feed conversion value. The cultivation of BSF maggot larvae is an emerging alternative in livestock farming, which can be used as feed and a decomposer for organic waste management. Maggot cultivation has positive and negative impacts influenced by several factors. One of the methods used to analyse environmental impact is Life Cycle Assessment (LCA), which is a method that simplifies the way to assess the potential environmental impacts related to production activities or service provision. Maggot farming is a profitable activity, but it is influenced by the methods and resources used. Therefore, it is necessary to conduct an impact and revenue analysis on a maggot farming business.
