This paper designs an energy allocation scheme based on maximum flow modeling for a microgrid containing renewable energy generators and consumer facilities. Basically, the flow graph consists of a set of nodes representing consumers or generators as well as a set of weighted links representing the amount of energy generation, consumer-side demand, and transmission cable capacity. The main idea lies in that a special node is added to account for the interaction with the main grid and that two-pass allocation is executed. In the first pass, the maximum flow solver decides the amount of the insufficiency and thus how much to purchase from the main grid. The second pass runs the flow solver again to fill the energy lack and calculates the surplus of renewable energy generation. The performance measurement result obtained from a prototype implementation shows that the generated energy is stably distributed over multiple consumers until the energy generation reaches the maximum link capacity.

Abstract The view of the logical positivism group regarding science is based on the development of exact sciences, scientific truth can be measured positively, namely the truth must be real, concrete, logical, accurate and useful, but the effect behind everything abstract and metaphysical in the dimensions of life is ignored and regardless of observation. The main idea of logical positivism that was promoted by Alfred Jules Ayer, one of which is the principle of verification. In the application of the verification principle, it can also be taken for study studies in the determination of Qiyas law, namely by analogizing a law that has not yet been stipulated in the text, by testing and observing by verifying the causes of its similarity with the established law, determining the similarity of causes with logical parameters. and also empirical. The analogy in Qiyas must go through a verification stage, namely because it must be a real and visible nature by the five senses, and logic, as well as through the empirical proof stage. According to logical positivism and qiyas, the main condition is that it must be something that is visible, and get rid of pseudo-problems. Keywords: Logical positivism, Verification, Qiyas.

Abstract Reading comprehension ability is potency of students to comprehend meaning of written texts, text details and main ideas. Furthermore, ability of reading comprehension activated learners to communicate with writers. To understand main ideas of written texts, help learners to be aware and to get particular messages from texts. Cognitive and metacognitive knowledges help readers to analyze, to summarize, to judge, and to distinguish main idea of reading texts and also more details about writer viewpoints to predicate and decision making to monitor text contents too. Monolingual students are those groups which must be aware about impacts of metacognitive strategy upon reading development and comprehension through to prepare and emanate bio feedbacks with teachers. Hence, monolingual groups have to be taught more than bilingual ones due to their low – proficiency levels and also their weak knowledge capacities about reading development strategies. Indeed, today understanding the effective strategies which help to learn language skills for all of scholars in TESOL domains is very significant, so every teacher that is aware about efficacy of those psychological strategies like cognitive and metacognitive or both; he or she is able to teach language skills particularly reading comprehension very conveniently and more productive language learning results. Without understanding reading strategy text comprehension to learn language skills is impossible.

Entrepreneurs are constantly looking for new models to address growing global challenges in a sustainable manner. Over the past several decades, those challenges have been identified and responded to through the development of social entrepreneurship. There is a number of research dealing with the theoretical concepts of those topics; however, the definitions and framework for action are different from country to country. Having in mind that the main idea of social entrepreneurship is to enable decent work for employees and to gain broader welfare for communities, the purpose of this paper is to analyse the development of social entrepreneurship in Croatia. The research is focused on recent developments, connecting key definitions and principles of social entrepreneurship with common trends and concrete case studies. This study’s results show that there are different approaches to social entrepreneurship globally. However, social entrepreneurship in Croatia develops within a clear legal framework. The current state of social enterprises is connected with respective public policies, while the number and types of social entrepreneurs are constantly rising in the last few years. The results of the analysis also show that there are still actions to be taken in order to encourage future policy measures aiming to support social entrepreneurs in Croatia.

The article presents the results of large-scale laboratory tests carried out in the conditions of the Chemical and Metallurgical Institute named after V.I. Zh. Abishev on the use of briquetted mono-charge in the smelting of carbon ferrochrome on a 250 kVA furnace. The purpose of these studies was to determine the technological parameters of the use of briquetted mono-charge containing in its composition chrome ore, wastes from the production of high-carbon ferrochrome, middlings and various carbonaceous reducing agents. The main idea of using these briquettes was to multiply the contact surface of the reductant and ore, which should speed up the technological process. The principal possibility of smelting a standard alloy using briquetted mono-charge is shown. The alloy for individual charge options meets the requirements of the standards. In comparison with the technology without the use of briquettes, the mono-charge technology has shown advantages in all main parameters. The technology with the use of briquettes from the dust of the AktZF gas cleaning system is distinguished by a low yield of non-standard metal and slag, the bulk of the material goes into the gas collection system. Technologies from briquettes from fines pellet production area of Donskoy ore mining and processing plant and flash have very low specific technical and economic indicators and cannot be recommended for industrial use. Improvement of briquetting modes and technology of their smelting is required. The technical and economic indicators were higher than the current one, showed briquettes from ore and coke of the People's Republic of China, briquettes of ore from borlin and shubarkol coals of Kazakhstan.

Since the beginning of the COVID-19 pandemic almost two years ago, there have been more than 700,000 scientific papers published on the subject. An individual researcher cannot possibly get acquainted with such a huge text corpus and, therefore, some help from artificial intelligence (AI) is highly needed. We propose the AI-based tool to help researchers navigate the medical papers collections in a meaningful way and extract some knowledge from scientific COVID-19 papers. The main idea of our approach is to get as much semi-structured information from text corpus as possible, using named entity recognition (NER) with a model called PubMedBERT and Text Analytics for Health service, then store the data into NoSQL database for further fast processing and insights generation. Additionally, the contexts in which the entities were used (neutral or negative) are determined. Application of NLP and text-based emotion detection (TBED) methods to COVID-19 text corpus allows us to gain insights on important issues of diagnosis and treatment (such as changes in medical treatment over time, joint treatment strategies using several medications, and the connection between signs and symptoms of coronavirus, etc.).
