This paper deals with the statistical analysis and pattern classification of electromyographic signals from the biceps of a person with amputation below the humerus. Such signals collected from an amputation simulator are synergistically generated to produce discrete elbow movements. The purpose of this study is to utilise these signals to control an electrically driven prosthetic or orthotic elbow with minimum extra mental effort on the part of the subject. The results show very good separability of classes of movements when a learning pattern classification scheme is used, and a superposition of any composite motion to the three basic primitive motions—humeral rotation in and out, flexion and extension, and pronation and supination. Since no synergy was detected for the wrist movement, different inputs have to be provided for a grip. In addition, the method described is not limited by the location of the electrodes. For amputees with shorter stumps, synergistic signals could be obtained from the shoulder muscles. However, the presentation in this paper is limited to biceps signal classification only.

Purpose The study aims to explore the classification of electronic games in Dewey decimal classification (DDC) and The Library of Congress classification (LCC) schemes. Design/methodology/approach The study adopted a comparative analytical method to explore the topic in both the DDC and the LCC schemes by comparing its processing method in both schemes. The study measures the extent to which both schemes succeed in allocating notations covering the topic’s literature. Findings The study reached several results, the most important of which are: the difference between the two main cognitive sections, to which they belong to the topic, namely, arts and recreation (700) in the DDC scheme and the geography section (G) in the LCC scheme, while they were found to share the same sub-section scheme. The two schemes do not allocate notations to address the subject of electronic games as literature and other notations that have not been embodied for electronic games themselves or in the form of a compact disc or other media. Originality/value As far as we know, this is the first paper that compares the treatment of video games in DDC and Library of Congress classification schemes. The study allows for understanding the difference in the treatment of topics in both schemes, which would help in the decision of the adoption of a particular classification scheme.

The subject are the bounded rationality agents of cyber security system. The purpose of this work is is to build a classification system for agents of a cybersecurity system with limited rationality. The tasks: consideration of the decisionmaking process by agents in cybersecurity systems, analysis of various manifestations of bounded rationality of agents of the cybersecurity system, introduction of classification features of bounded rationality, formal presentation of bounded rationality of various types, combining agents with various types of bounded rationality into a whole classification system. Results. Presents approaches to the classification of the concept of rationality in relation to cybersecurity systems. Such types of rationality are considered as strong, semi-strong, weak. Further classification of types of rationality is carried out on the basis of the place of manifestation of rationality. For this, the decision-making process in the cybersecurity system has been considered, formal relations have been introduced, which characterize its various stages. Such types of bounded rationality as informational, methodological, predictive, evaluative and conditional are considered. The ratio of the considered types of rationality is presented. Conclusion: A comparison of various types of bounded rationality, based primarily on its place in the decision-making process, made it possible to propose a classification scheme of bounded rationality characteristic of agents of the cybersecurity system. The result of the formalization of the description of bounded rationality is presented, which can be used as the basis for the development of models of behavior of interacting agents of cybersecurity systems.

Both traditional and digital libraries are the storehouse of information and indispensable in this age of computerization and digitization of information. As cataloguing is one of the pillars of library services and because cataloguing plays a pivotal role for a successful library operation, a discussion and description of cataloguing process is inevitable. This chapter discusses the steps involved in cataloguing- descriptive, assigning a subject to the document and allocating a classification mark to the picked subject from the subject heading list. It also describes schemes which are specialized and deals only with the subject areas involved, like NLM (National Library of medium) classification scheme and Moys classification for law. The three basic types of classification structure - enumerative, analytic-synthetic, and faceted classification scheme are explained as well. The important activities of library automation, ways of doing copy cataloguing, meaning, procedures, and sources of copy cataloguing are also briefly explained. As automated library system is an important part of libraries nowadays, this chapter further discusses the meaning of computerized cataloguing: the MARC format/records. The role of MARC is also explained in the simplest terms possible as well as the basic information needed to understand MARC record.

Ethiopian-Semitic constitutes a compact, readily defined and homogeneous linguistic family, consisting of Ge' ez, Tigre, Tigrinya, Amharic, Argobba, Harari, Gafat, and the Gurage cluster. The most recent attempt to set up a classification of Ethiopian-Semitic was Hetzron [1972}, but this work was rather thoroughly criticized by Goldenberg [1977], and the field has yet to recover from it. The present note seeks to open the classification question anew by providing a basic, minimalist classification scheme, which can serve as a starting-off point for any future work on the subject. We begin with some of the results of Marcel Cohen [1931], "the father of Ethiopian studies" in the twentieth century. Cohen treats Tigre and Tigrinya as Northern Ethiopic, and Amharic, Harari, and the Gurage cluster as Southern Ethiopic. All are ultimately descendants of a ProtoEthiopic koine most closely resembling Ge'ez. Gurage, according to Cohen, is not a language or a linguistic unit in itself, but rather an ensemble of at least two separate and mutually unintelligible dialect clusters, Eastern Gurage and Western Gurage. Eastern Gurage consists of Wolane, Selti-Ulbarag, (and in the present state of our knowledge also Zway) , and is most closely connected with Harari. Western Gurage consists of several subgroups of dialects, in particular (a) Chaha, Ezha, Ennemor (Inor), Gumar, Gyeto (and in the present state of our knowledge Endegefi) and (b) Muher, Gogot, Masqan. Aymallel (Soddo, Kgstangiiiia), another Gurage tongue, is left unclassified by Cohen, as being perhaps intermediate between the two groups. Tentatively, he terms it North-Eastern Gurage. (Gafat and Argobba are not classified by Cohen.) Cohen's classification may be modified and/or expanded on the basis of the following points. Western Gurage tongue.

This given article reveals the topicality not only of destructive, but also of constructive, as well as hybrid conflicts. Practically it has been done for the first time. It also describes the history of the formation of both foreign and domestic social conflictology. At the same time, the chronology of the development of the latter is restored and presented objectively, in full, taking into account the contribution of those researchers who actually stood at its origins. The article deals with the essence of the socio-psychological approach to understanding conflicts. The subject of social conflictology includes the regularities of their occurrence and manifestation at various levels, spheres and conditions, including normal, complicated and extreme ones. Social conflictology includes the theory and practice of diagnosing, resolving, and resolving social conflicts. It analyzes the difficulties that occur in defining the concept, structure, dynamics, and classification of social conflicts. Therefore, it is no accident that the most important task is to create a full-fledged theory of social conflicts. Without this, it is impossible to talk about effective settlement and resolution of social conflicts. Social conflictology is an integral part of conflictology. There is still a lot of work to be done, both in theory and in application, for its complete design. At present, there is an urgent need to develop conflict-related competence not only of professionals, but also for various groups of the population.

To explore whether the brain contains pattern differences in the rock–paper–scissors (RPS) imagery task, this paper attempts to classify this task using fNIRS and deep learning. In this study, we designed an RPS task with a total duration of 25 min and 40 s, and recruited 22 volunteers for the experiment. We used the fNIRS acquisition device (FOIRE-3000) to record the cerebral neural activities of these participants in the RPS task. The time series classification (TSC) algorithm was introduced into the time-domain fNIRS signal classification. Experiments show that CNN-based TSC methods can achieve 97% accuracy in RPS classification. CNN-based TSC method is suitable for the classification of fNIRS signals in RPS motor imagery tasks, and may find new application directions for the development of brain–computer interfaces (BCI).
