However, there are some problems in the analysis of objects, for example, there is a priori uncertainty about the state of objects and the analysis takes place in a difficult situation against the background of intentional (natural) interference and uncertainty. The best solution in this situation is to integrate with the data analysis of information systems and artificial neural networks. This paper develops an improved method for finding solutions for neuro-fuzzy expert systems. The proposed method allows increasing the efficiency and reliability of making decisions about the state of the object. Increased efficiency is achieved through the use of evolving neuro-fuzzy artificial neural networks, as well as an improved procedure for their training. Training of evolving neuro-fuzzy artificial neural networks is due to learning their architecture, synaptic weights, type and parameters of the membership function, as well as the application of the procedure of reducing the dimensionality of the feature space. The analysis of objects also takes into account the degree of uncertainty about their condition. In the proposed method, when searching for a solution, the same conditions are calculated once, which speeds up the rule revision cycle and instead of the same conditions of the rules, references to them are used. This reduces the computational complexity of decision-making and does not accumulate errors in the training of artificial neural networks as a result of processing the information coming to the input of artificial neural networks. The use of the proposed method was tested on the example of assessing the state of the radio-electronic environment. This example showed an increase in the efficiency of assessment at the level of 20–25 % by the efficiency of information processing","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"122 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74848629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been determined that the feasibility of using fuzzyTECH-based fuzzy modelling is explained by the fact that there is a possibility to specify the levels and values of linguistic variables for these levels. Moreover, the fuzzyTECH software package makes it possible to automate this process. A block diagram of the algorithm was built to introduce fuzzy modelling by means of fuzzyTECH into managing the risks of economic entities. The proposed steps are general for use by economic entities in various fields of activity. Based on the constructed block diagram of the managerial decision-making algorithm, it is advisable to apply it at the level of intermediate values of the intervals of each individual indicator, as well as for the obtained levels of risk of the activities of economic entities. These levels of risk were determined to be very high, high, medium, low, and very low. Depending on the level of risk to economic entities, it is advisable to develop appropriate measures and make managerial decisions. It is essential to include among them the development of measures for quick and gradual responses, tactical and strategic, as well as measures already at the level of the economic entity’s strategy. In order to test the block of the algorithm responsible for the assessment, the system of techniques for assessing the risks of activities was tested for the studied economic entities. The intervals of the values of the scale selected to assess to indicators were obtained; a fuzzy model to estimate the risks of the economic entities by means of fuzzyTECH was built, set, and tested, and a system of fuzzy inference was obtained. Using the tools of fuzzy sets, a model for calculating the number of points for the aggregate assessment of the risks of the researched economic entities was built. It constitutes the preconditions for the transfer of the obtained scientific and practical results already into the system of risk-oriented management of economic entities","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"28 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72454406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we study how these debiasers generalize with respect to both out-of-sample test error for computing fairness -- performance and fairness -- fairness trade-offs, and on the change in other fairness metrics that were not explicitly optimised. Our results demonstrate that out-of-sample performance on fairness and performance can vary substantially and unexpectedly. Moreover, the variance in estimation arises from class imbalances with respect to both the outcome and the protected classes. Our results highlight the importance of evaluating out-of-sample performance in practical usage.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72795708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, luminescence quenching of down-conversion phosphors under high-power-density excitation severely restricts the luminous efficacy and light output of laser-driven lighting devices. Till now, the quenching mechanism, once assigned to thermal quenching, is still argued, making it difficult to select appropriate laser phosphors. In this work, we identify the optical excitation quenching (a non-thermal quenching effect) rather than thermal quenching that dominates the luminescence loss of Ce3+- and Eu2+-doped phosphors under high-power-density excitation. The optical excitation quenching is mainly caused by the energy-transfer upconversion (ETU), and the quenching rate is greatly dependent on the decay time of phosphors, evidenced by combining the experimental data with theoretical models. A critical parameter, named as optical excitation quenching behavior, is finally proposed to screen laser phosphors.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90504267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When using a fast heating rate of 100oCs -1 , it was found that the α-microstructure and α-texture developments during the early stage of heating, prior to noticeable phase transformation, and the β-texture in the two-phase regime are greatly affected by the RX and CW conditions. During transformation on heating, variant selection does not occur and the β-texture is weak, but different for both starting conditions. During β-grain growth in the single β-phase regime, the β-texture strengthens. During transformation on cooling, variant selection occurs early in the nucleation of the α-phase. However, there is no or little variant selection in the CW condition. A difference in chemical composition between the zirconium alloys does not affect transformation textures and variant selection. The findings provide accurate inputs of texture for zirconium fuel claddings when modelling their mechanical behaviour in LOCA. The link between deformation, fast heating rates and microstructure evolution might also be relevant for other processes like additive manufacturing and forging in the two-phase region.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73318052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant advances in display technology are steadily developing visual environments from CRTs to New Quantum Dots Technology as per improvement in the modern age. The visual environment starts with the small LED (Light Emitting Diode) display that displays numerical contain, then after jumbo CRT (cathode ray tubes) The evolution continued from a lighter and simpler to bring LCD (Liquid Crystal Display), but the key issue with LCD is that it does not see consistent images from various angles. The ground-breaking discovery of OLED overcame this challenge (Organic Light Emitting Diode). The inhabitants of the Planet are faced with a severe lack of energy supplies due to the increased population and consumption of more energy. The main concern of researchers and producers is thus directly related to the use of energy. A lot of research has been done in recent years to attain efficient and low-energy sources of light.

A probabilistic thematic model was built to make it possible to cluster the publications of scholars in scientific areas, taking into account the citation network, which was an important step for solving the problem of identifying scientific subject spaces. As a result of constructing the model, the problem of increasing instability of clustering the citation graph in connection with a decrease in the number of clusters was solved. This problem would arise when combining clusters built on the basis of citation graph clustering, taking into account the similarity of abstracts of scientific publications. In the article, the presentation of text documents is described based on a probabilistic thematic model using n-grams. A probabilistic thematic model was built for the task of determining the completeness of covering the materials of an author’s dissertation research in scientific publications. The approximate values of the threshold coefficients were calculated to evaluate whether the articles of an author included the research provisions that were reflected in the text of the author’s abstract of the dissertation. The probabilistic thematic model for an author’s publications was practised on the basis of the BigARTM tool. Using the constructed model and with the help of a special regularizer, a matrix was found to evaluate the relevance of topics specified by the segments of an author’s dissertation abstracts to documents that are produced by the author’s publications. Important aspects of the possibilities of using latent semantic analysis were studied to identify tasks of scientific subject spaces and to reveal the completeness of covering the results of dissertation research science degree seekers.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"2012 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88152447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
