Differential Current

False operation of the differential current protection leads to tripping of the most important electrical power objects. Fault of current transformer’s secondary circuits is one of the most often cause of false operation of the differential current protection. Early determination of this malfunction increases the reliability of the differential current protection and reduces the number of false trips. In the present article the methods of secondary open circuit determining for the differential protection are described. Some of the methods react instantly to the malfunction of secondary current circuits, and the other part identifies fault after a certain time delay. Each of considered methods has its advantages and disadvantages. A new method for determination secondary open current circuits based on the analysis of increments of the RMS values of differential and braking currents has been proposed. In this case, increments are calculated for half the period of the industrial frequency, which provides quick fault determining. The use of the sum and the difference between the increments of the brake and differential currents makes it possible to determine the open circuits in the most sensitive way. The method can be adapted to work with any type of differential protection, including transformer protection. The evaluation of the increment of the RMS current value is performed taking into account the transient process in the Fourier filter. With the aid of a computational experiment, the error limit of such an estimate is determined. The block diagram of algorithm of determination of open circuits on the basis of the analysis of increments of the acting values of brake and differential currents is presented; the principle of its functioning is described. The parameters of operation are determined. The limits of sensitivity of the method are determined, too. The time characteristics of the algorithm have been determined by the method of computational experiment with the of the MatLab Simulink simulation environment.

This paper aims at finding the most dominant ideas about the marketing of healthcare systems highlighted in the mainstream literature, with a focus on Russia and Romania. To reach this goal, a systematic analysis of literature was conducted and various competitive advantages and disadvantages of the medical models that require special attention from the governments are considered. In this respect we examined 106 papers published during 2006 to 2020 found on four scientific databases. They were selected using inclusion and exclusion criteria according to PRISMA methodology. The main findings of the research consist of the opportunity to use marketing tools in order to improve the quality of healthcare systems in the named countries. Thus, using market orientation, the managers of healthcare systems could stimulate the innovation, the efficiency of funds allocation and the quality of medical services. The results will lead to a better quality of population life and to an increasing of life expectancy. As this paper reviews some articles from Russian literature, it can add a new perspective to the topic. These outcomes have implications for government, business environment, and academia, which should cooperate in order to develop the healthcare system using marketing strategies.

The paper investigates and explains a new simple analytical tuning of proportional-integrative-derivative (PID) controllers. In combination with nth order series binomial low-pass filters, they are to be applied to the double-integrator-plus-dead-time (DIPDT) plant models. With respect to the use of derivatives, it should be understood that the design of appropriate filters is not only an implementation problem. Rather, it is also critical for the resulting performance, robustness and noise attenuation. To simplify controller commissioning, integrated tuning procedures (ITPs) based on three different concepts of filter delay equivalences are presented. For simultaneous determination of controller + filter parameters, the design uses the multiple real dominant poles method. The excellent control loop performance in a noisy environment and the specific advantages and disadvantages of the resulting equivalences are discussed. The results show that none of them is globally optimal. Each of them is advantageous only for certain noise levels and the desired degree of their filtering.

PurposeThe purpose of this paper is to investigate how to overcome the dilemma of the lack of student workforce readiness upon graduation. Based on experiential learning theory, the authors propose an innovative three-step approach to marketing curriculum to help address this dilemma.Design/methodology/approachThis study examines both quantitative and qualitative data. First, quantitative results were obtained from 5,222 end-of-course surveys of students taking an experiential learning course at a southeastern United States public university. Results were also obtained from 111 end-of-course surveys of students taking experiential learning courses in marketing. Second, qualitative results were obtained through a critical review of self-reflection assignments from over 1,000 students taking a variety of experiential learning marketing courses.FindingsThe authors identify a three-step process that can be used to develop curriculum that will better prepare students for entering the workforce. The advantages and disadvantages associated with this type of curriculum are also discussed. The outcomes indicate that an entire curriculum focused on experiential learning, self-reflection and ePortfolios will allow students to not only be better prepared for the workforce but also will help them be better communicators on what they have learned.Originality/valueIn this paper, the authors contribute to the literature by providing a curriculum-based approach to learning in order to minimize the gap between academic knowledge and workforce preparedness. Sample course projects, reflective prompts and grading rubrics are provided to aid others in the implementation of this type of curriculum.

This article analyzes the choice-of-law interests of specific and potential participants in the relations of intellectual property rights and the state in order to establish the closest connection of the above type of relation with the state, whose law should be applied. Taking into account the directionality of significant choice-of-law interests, advantages and disadvantages of territorial and universal approaches, a theoretically based solution is proposed for the formation of a general choice-of-law rule on the law to be applied to the relation of intellectual property rights. It was revealed in the study that the diversity of the relations of intellectual property rights (their obligatory and non-obligatory, property and personal non-property nature, other differences in legal features) does not automatically generate a multidirectionality of significant choice-of-law interests that should be taken into account when establishing a close connection of the above type of the relation with the state for determination of applicable law, does not prevent the formation of a general choice-of-law rule for the relations of intellectual property rights in general and does not unequivocally testify in favor of the specialization of its binding. However, the diversity of the relations of intellectual property rights should be examined and evaluated for the feasibility and limits of exceptions from the general choice-of-law rule and the development of special rules for resolving certain private of the relations of intellectual property rights.

According to the World Health Organization (WHO), 71 million people were living with Hepatitis C virus (HCV) infection worldwide in 2015. Each year, about 399,000 HCV-infected people succumb to cirrhosis, hepatocellular carcinoma, and liver failure. Therefore, screening of HCV infection with simple, rapid, but highly sensitive and specific methods can help to curb the global burden on HCV healthcare. Apart from the determination of viral load/viral clearance, the identification of specific HCV genotype is also critical for successful treatment of hepatitis C. This critical review focuses on the technologies used for the detection, discrimination, and genotyping of HCV in clinical samples. This article also focuses on advantages and disadvantages of the reported methods used for HCV detection, quantification, and genotyping.

AbstractUnderstanding the growth of whiskers or high aspect ratio features on substrates can be aided when the crystallography of the feature is known. This study has evaluated three methods that utilize electron backscatter diffraction (EBSD) for the determination of the crystallographic growth direction of an individual whisker. EBSD has traditionally been a technique applied to planar, polished samples, and thus the use of EBSD for out-of-surface features is somewhat more difficult and requires additional steps. One of the methods requires the whiskers to be removed from the substrate resulting in the loss of valuable physical growth relationships between the whisker and the substrate. The other two techniques do not suffer this disadvantage and provide the physical growth information as well as the crystallographic growth directions. The final choice of method depends on the information required. The accuracy and the advantages and disadvantages of each method are discussed.

The subject of this research is the development of the architecture of expert system for distributed content aggregation system, the main purpose of which is the categorization of aggregated data. The author examines the advantages and disadvantages of expert systems, toolset for development of expert systems, classification of expert systems, as well as application of expert systems for categorization of data. Special attention is given to the description of architecture of the proposed expert system, which consists of spam filter, component for determination of the main category for each type of the processed content, and components for determination of subcategories, one of which is based on the domain rules, and the other uses the methods of machine learning methods and complements the first one. The conclusion is made that expert system can be effectively applied for solution of the problems of categorization of data in the content aggregation systems. The author establishes that hybrid solutions, which combine an approach based on the use of knowledge base and rules with implementation of neural networks allow reducing the cost of the expert system. The novelty of this research lies in the proposed architecture of the system, which is easily extensible and adaptable to workloads by scaling existing modules or adding new ones. The proposed module for spam detection leans on adapting the behavioral algorithm for detecting spam in emails; the proposed module for determination of the key categories of content uses two types of algorithms: fuzzy fingerprints and Twitter topic fuzzy fingerprints that was initially applied for categorization of messages in the social network Twitter. The module that determine subcategory based on the keywords functions in interaction with the thesaurus database. The latter classifier uses the reference vector algorithm for the final determination of subcategories.
