This dehazing algorithm, called the DCP scheme here, is well-known to have four main problems in its dehazed images: artifacts, hue distortion, color over-saturation, and halos. In this paper, an improved DCP (IDCP) is proposed to deal with the four aforementioned problems, by setting the model parameters, i.e. scaling factors and window size and smoothing factor of a guided image filter in the DCP scheme. Note that a dehazed image is generally dim and low in contrast. An adaptive gamma correction (AGC) is introduced for dehazed image enhancement. The proposed IDCP and AGC are used to create the IDCP/AGC scheme, in which the IDCP scheme performs haze removal and the AGC enhances the dehazed image. The IDCP/AGC scheme was justified through extensive experiments and compared with the DCP scheme, an optimization-based scheme, and two learning-based schemes on two datasets. The results indicated that the proposed scheme is subjectively and objectively superior to the comparison schemes.","PeriodicalId":39095,"journal":{"name":"Advances in Systems Science and Applications","volume":"21 1","pages":"95-112"},"PeriodicalIF":0.0,"publicationDate":"2021-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48180499","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}

Obtained clusters, which rely solely on the geometry of polymer chains and not on the chemical class (polyamides, polyacetylenes, etc.), are shown to discriminate polymers with respect to their transport properties, in particular, the coefficient of diffusion. The method proposed consists of several steps. Firstly, realistic conformations of large polymer macromolecules are constructed using the program code developed in the RDKit environment for Python. Then, polymer conformations are characterized by a curve that relates the “accessible surface area” (i.e., the contact surface between the spherical model of a macromolecule and a spherical “probe”) to the radius of this probe, and also seven similar curves, which relate the polarized (neutral, positively or negatively charged, etc.) accessible surface area to the radius of the spherical probe that represents the variety of penetrant gases. An improved algorithm for surface area calculation maps out the outer surface of the macromolecule to eliminate its influence. The curves are averaged between ten polymer conformations to obtain more robust figures. Finally, agglomerative clustering is used to separate different polymers in the space of these curves that align their accessible-surface-area-related quantities against the probe radius. The proposed classification of polymers can be used to develop more precise predictive models of polymers’ transport properties for the theory-guided and computer-aided materials design.","PeriodicalId":39095,"journal":{"name":"Advances in Systems Science and Applications","volume":"20 1","pages":"91-104"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43457887","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 is assumed that the top-level player has the right of the first move. It is believed that the lower level player at the time of decision making knows exactly the realization of the random factor and the choice of partner. And the top-level player at the time of decision making knows only a probabilistic measure on the set of values of an uncertain factor. The principle of optimality is new: it is believed that a top-level player is ready to neglect some of the \"unpleasant\" events, the total probability of which is given, but otherwise he is careful. Under these assumptions, the maximum guaranteed result of the top-level player is calculated. The structure of strategies providing such a result is clarified. Two cases were investigated: a game with and without feedback. To solve the problem, an original definition of the maximum guaranteed result is proposed. It is equivalent to the classical definition, but is simpler. Using this technique, solving of the problem reduces to identical transformations of the formulas for predicate calculus. As a result of the solution, the optimal strategy and the set of \"unpleasant\" cases which are excluded from consideration search task is reduced to calculating multiple maximins on finite-dimensional spaces. In this case, the operation of calculating the expected value with respect to given probabilistic measure is considered to be \"elementary\". Models of this type can have different interpretations. One can use them for methodological justification of the principle of maximum guaranteed result. One can use them when solving risk management tasks. One can consider them as models for managing the \"customer base\" of the service company. The proposed method allows to study such models at a qualitative level, and in some cases to obtain quantitative results.","PeriodicalId":39095,"journal":{"name":"Advances in Systems Science and Applications","volume":"20 1","pages":"24-35"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43928838","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}

These new kinds of markets post significant challenges to the world of learning and decision-making managers, entrepreneurs and alike. To confront these challenges, this paper investigates the potentials of value creation and value capture at the firm level from different perspectives. By employing systems methodology and the logical reasoning that parallels the one commonly used in mathematics and natural science, this paper establishes 16 formal propositions on value creation and value capture from the respective perspectives of market competition, innovation, resource, inter-organizational network, and direct association of sellers and buyers. In particular, this work points out (1) when innovation provides additional potentials for value creation; (2) when resources’ latent values can be practically made visible through value creation; (3) how markets’ mutual forbearance and relatively sustainably increased profitability are positively related, (4) why a firm’s systemic hole position offers advantages and profitability to the firm, (5) how a firm’s profitability is positively affected by its membership in a strategic block of increasing market influence; and (6) when a firm creates and maintains convenient platforms it will readily create and capture values. This paper concludes with some practically reliable general recommendations and a few topics and directions for future research.","PeriodicalId":39095,"journal":{"name":"Advances in Systems Science and Applications","volume":"20 1","pages":"50-72"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47218612","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}

The mechanisms of transformation of regional specializations are investigated. The productive role of the concept of \"smart specialization\" for socio-economic and industrial development is noted. The empirical base of the study was Russia’s statistics for 2010-2018. The method of correlation and regression analysis identifies the influence of the way of using digital technologies on the development of traditional industries. The factors affecting the functioning of the industrial sector of Russia were identified. The current requirements and approaches to identifying the priorities of specialization of a region are given. As a result of the study, it was concluded that in order to transform traditional specialization industries and increase their competitiveness in modern conditions, their active interaction (integration and associated participation in production chains) with high-tech fast-growing industries is paramount. As expected, the introduction of new digital technologies will contribute to the growth of traditional industries, which will lead to an increase in their economic sustainability.","PeriodicalId":39095,"journal":{"name":"Advances in Systems Science and Applications","volume":"20 1","pages":"36-49"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45971663","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}
