This article discusses the problems of the influence of electromagnetic compatibility (EMC) violations of electrical and electronic devices on the surrounding ecosystems. The analysis is carried out and the classification of EMC violations is given, the causes of the compatibility violation are examined, and the economic losses and the negative environmental impact, as a consequence of the considered violations, are analyzed. A classification and generalization of methods to minimize the negative consequences of EMC violations was carried out, criteria for reducing economic losses were considered, methods for preventing and preventing EMC violations of various power and electronic devices were classified. The methods of monitoring the compatibility of devices are considered and recommendations are given for observing the necessary safety and control requirements.

The purpose of this study is to evaluate the trophic state of five lakes in southern Yellowstone National Park in order to determine if the human activity in the local area is having a negative environmental impact and possibly increasing the eutrophication rate. While some previous analyses have been done on these lakes, this study is intended to be a preliminary trophic state evaluation to which future analyses can be compared. The five lakes sampled are Shoshone Lake, Lewis Lake, Heart Lake, Riddle Lake, and Duck Lake. Each lake, with the exceptions of Riddle Lake and Duck Lake, was sampled at several locations. These samples were taken during the months of June through August of 1999 by Woodruff Miller and Dave Anderson of the BYU Civil & Environmental Engineering Department.

Purpose – to elucidate the «economic nature» of an emergencies, to expand the list of reasons for the formation and consequences of the emergencies, taking into account the economic component, and to provide a description of their interrelation in this process. Design/Method/Approach. This work evaluates and summarizes studies that provide economic characteristics and assess the causes and consequences of a emergencies. Findings. An analysis of previous studies on emergencies pointed to a limited focus on economic issues associated. In this paper, the authors substantiated the feasibility and proposed to highlight the economic component in the  management of prevention of emergencies,  in the management of minimizing negative consequences and to consider this component in the classification of types of emergencies. This work focuses on the causal link between economic costs for the prevention, elimination and elimination of the effects of emergencies (economic losses) in the emergency management system. The examples have proved that all of the emergency preceding processes are economical, that emergency actions are limited to an economic factor, and that emergency situations can have economic consequences. An economic component can be both a cause and a consequence of an emergency. At the same time, the economic causes of emergencies directly affect only the economic consequences (inflation - impoverishment of the population), and their impact on the remaining consequences - indirect, due to the impact of other factors-consequences. Theoretical implications. This research identifies a new classification group "economic circumstances" in the classification of types of emergencies for the causes of the emergence and spheres of manifestation of the consequences. Practical implications. The isolation and systematization of the economic component of emergencies allows us to take into account the economic factor in the development of appropriate prevention algorithms, actions in emergencies or actions to eliminate the negative effects of these events. Originality/Value. The originality of the work is to illustrate the connection between the cause of emergencies and each of its manifestations with the help of the fan matrix. This approach has allowed a clearer outline and a clear indication of the causal relationship in the processes associated with the emergency situation. For example, a causal relationship with the types of emergencies based on the economic component is illustrated with the aid of a fan matrix. Research limitations/Future research. This research is the basis for further improvement of approaches to the estimation of economic indicators of emergencies taking into account the proposed classification groups of types of emergencies. Paper type – theoretical.

The paper discusses the process of integrating scientific equipment into the Russian Segment of the International Space Station (ISS RS) to conduct space experiment using the ISS IS information and control system. The paper addresses the stages in ground processing of scientific equipment that are critical for its successful operation after delivery to the ISS RS: tests on the hardware (vibration and hydraulic tests, electromagnetic compatibility tests, incoming inspection), development of the software for the equipment using ground debugging facility and conducting integrated tests in the checkout facility. It points out the need to update the existing stages of ground preparations for experiments to reduce the hardware ground processing time. Taking as examples the space experiment Terminator and experiments conducted using cargo transportation spacecraft Progress, the paper resents results obtained through the use of the described approach. Key words: information and control system, scientific equipment, space experiment, International Space Station, logistics spacecraft Progress, microgravity.

This chapter discusses basic concepts from control theory and machine learning to facilitate a formal understanding of animal learning and motor control. It first distinguishes between feedback and feed-forward control strategies, and later introduces the classification of machine learning applications into supervised, unsupervised, and reinforcement learning problems. Next, it links these concepts with their counterparts in the domain of the psychology of animal learning, highlighting the analogies between supervised learning and classical conditioning, reinforcement learning and operant conditioning, and between unsupervised and perceptual learning. Additionally, it interprets innate and acquired actions from the standpoint of feedback vs anticipatory and adaptive control. Finally, it argues how this framework of translating knowledge between formal and biological disciplines can serve us to not only structure and advance our understanding of brain function but also enrich engineering solutions at the level of robot learning and control with insights coming from biology.

Rhodococcus fascians is an important pathogen that infects various herbaceous perennials and reduces their economic value. In this study, we examined R. fascians isolates carrying a virulence gene from symptomatic lily plants grown in South Korea. Phylogenetic analysis using the nucleotide sequences of 16S rRNA, vicA, and fasD led to the classification of the isolates into four different strains of R. fascians. Inoculation of Nicotiana benthamiana with these isolates slowed root growth and resulted in symptoms of leafy gall. These findings elucidate the diversification of domestic pathogenic R. fascians and may lead to an accurate causal diagnosis to help reduce economic losses in the bulb market.
