In fifth generation and beyond Internet of things (5G-IoT), the buffer-aided relaying network provide an efficient way to maintain the coverage area and enhance the edge user’s transmission experience. However, the effect of non-ideal factor to the buffer-aided relaying network, such as the signaling overhead, have not been investigated. In this paper, we propose a practical hybrid bit-level network coding (BNC) for the buffer-aided relaying network while taking the unreliable transmission, limited relay-buffer size and signaling overhead into consideration. Afterward, we derive its concise closed-form expressions and the associated upper bound expressions for the throughput, queuing delay and overflow probability. Monte-Carlo simulation proves the validness of our analysis. Simulation results also demonstrate that compared to existing studies, our proposal can enhance the system energy efficiency (EE) performance, and buffer size has a positive effect on the EE performance.

The fifth generation (5G) of wireless communications has led to many advancements in technologies such as large and distributed antenna arrays, ultra-dense networks, software-based networks and network virtualization. However, the need for a higher level of automation to establish hyper-low latency, and hyper-high reliability for beyond 5G applications requires extensive research on machine learning with applications in wireless communications. Thereby, learning techniques will take a central stage in the sixth generation of wireless communications to cope up with the stringent application requirements. This paper studies the practical limitations of these learning methods in the context of resource management in a non-stationary radio environment. Based on the practical limitations we carefully design and propose supervised, unsupervised, and reinforcement learning models to support rate maximization objective under user mobility. We study the effects of practical systems such as latency and reliability on the rate maximization with deep learning models. For common testing in the non-stationary environment, we present a generic dataset generation method to benchmark across different learning models versus traditional optimal resource management solutions. Our results indicate that learning models have practical challenges related to training limiting their applications. These models need an environment-specific design to reach the accuracy of an optimal algorithm. Such an approach is practically not realistic due to the high resource requirement needed for frequent retraining.

The paper semantically analyzes the corporeality in the poetic discourse of Momčilo Nastasijević. The verses indicate the semantic structure of the body through its sensuous, affective and ontological segment. The conceptual distinction between the body and corporeality is emphasized, by pointing to the body as a conceptual domain that is conceptualized through the plant world and corporeality as a quality that arises in bodily intercommunication. Corporeality is semantically formed in the fusion of bodily relationship and the dynamics of its meaning finds the words whose semantic content is dynamic, and in most cases these words are lexemes that denote processes in the vegetative world. Corporeality is not limited to the material appearance of the body, but is recognized as a space in which the body exists incorporeal and immaterial. Corporeality arises in the human physical-physiological substance of the body, but at the same time it is in the human being an inseparable form with the soul (feelings). There is an ontological component of meaning of the corporeality based on Christian ethical theses. Corporeality is also a metaphysical presupposition of human existence. It is confirmed in the songs with verses about the insatiability of thirst, i.e., eros, which is not bare libido sexualis, but longing and necessity for another being, i.e., the necessity to know the spiritual and divine principle through another body (another being). The function of desire is also shown in conceptual representations of corporeality. According to the poet's essays, desire is the disharmonization of the human personality, and that connotation predetermines the negative meaning of corporeality. In that sense, the body is a state of death and carries the potential for perversion. Hence, the thought of bodily renunciation and prohibition of bodily desire appears in the verses, which is also the influence of Christian views on Nastasijević's poetics and semantics of corporality.

The term Industry 4.0 was created as part of a strategic document by the German government aimed at integrating the internet of things and services into the production environment (i.e., the formation of cyber-physical systems). One of the basic tools of artificial intelligence is search and optimization. The task of optimization is to search and find the best possible solution from the solution space. When defining product form and structure during product design, structure optimization is among the essential stages. Believing that the product must be optimized, modern CAD systems have begun to implement structure optimization as an option during product design. Based on the previously mentioned in this chapter, heuristic optimization methods will be presented with special reference to genetic algorithms, particle swarm optimization, ant colony optimization, and their application in structure optimization. Some software that offer the option of optimization, either as a separate package or as an option of a CAD system, are given at the end of this work.

This study analyses the process of adopting of the sign language with deaf and hard of hearing preschool children in the context of the result of linguistic and psycholinguistic research. The importance of the sign language is emphasized and its historical development is analyzed. It is pointed to the significance of the critical period for the adoption and the learning of the sign and spoken language with deaf and hard of hearing preschool children. The sign language is natural and primary linguistic expression of deaf children. Deaf and hard of hearing children are exposed to the sign and spoken language, they have better understanding and linguistic production than the children who are only exposed to the spoken language. Bilingualism involves the knowledge and the regular use of the sign language, which is used by the deaf community, and of the spoken language, which is used by the hearing majority. Children at the preschool age should be enabled to continue to adopt the language they started to adopt within the family (the sign language or the spoken language). Children will adopt the best both linguistic modalities through the interaction with other fluent speakers (the adults and children).

A way of communication on an equal footing with oral and written speech is sign language. Oral speech is a common way of communication, written speech has, with the development of information technologies, been taking up more and more space. In a parallel with them, communication can also take place through sign language, which is, to deaf people, as well as to all those who use it, a natural, simple and easy way to communicate. Relationship towards sign language has changed significantly throughout history from acceptance and isolated use, to complete rejection, and then to encouraging its adoption and emphasizing its importance for the cognitive, emotional, educational, social, and general development of deaf children. Serbian Sign Language (SSL) serves deaf people in Serbia as a means for everyday communication, for expressing desires, willingness, for learning, for intellectual discussions, for expressing personal style. Although the standardization of the Serbian Sign Language was completed in 2015, even nowadays we may still find certain gestures of expression varying in different regions. Different countries have different sign languages that are not reciprocally understood in use. They are distinguished by their own grammar (semantics, morphology, and syntax), different from the grammar of spoken languages. The distinguishing and recognition of sign languages in the world has led to changes in the field of education of deaf children. In bilingual schools, children acquire both sign and spoken languages, and teachers know both of the mentioned languages. The importance of sign language in the education of deaf children is emphasized.

The consequences of improper land management are long-term, inadequate for agricultural production, and reflected through the loss of land, reduced yields, soil erosion, etc. In order to determine the optimal role or suitability of the land for apple cultivation within the Bužim municipality, a survey was conducted according to the FAO method of AEZ (FAO, 1976), and based on the obtained results, an assessment of the suitability of the land for apple cultivation was carried out. It was found that a significant land portion of the total of 13,026.27 ha agricultural land within the Municipality of Bužim is suitable for fruit production marked from S1 to N suitability class. Thus, the areas with the best graded class S1 cover only 1.23% or 159.52 ha, the S2 class occupies 5.51% (717.24 ha), the S3 class occupies 2.29% (298.24 ha). However, the largest areas are marked as the unfavourable N-class with 36.68% (4,772.60 ha). It is evident that pre-existing conditions for apple production within the municipality do exist. With the implementation of the necessary measures of soil/ land regulation, education of agricultural producers, and mindfulness of constraint factors hindering intensive production such as terrain slope, depth, rockiness and soil response, progress in production can be made. Key words: municipality of Bužim, soil suitability, apple, AEZ.
