Non-cooperative intelligent control agents (ICAs) with dedicated cost functions, can lead the system to poor performance and in some cases, closed-loop instability. A robust solution to this challenge is to place the ICAs at the feedback Nash equilibrium point (FNEP) of the differential game between them. This paper introduces the designation of a robust decentralized infinite horizon LQR control system based on the FNEP for a linear time-invariant system. For this purpose, two control strategies are defined. The first one is a centralized infinite horizon LQR (CIHLQR) problem (i.e. a supervisory problem), and the second one is a decentralized control problem (i.e. an infinite horizon linear-quadratic differential game). Then, while examining the optimal solution of each of the above strategies on the performance of the other, the necessary and sufficient conditions for the equivalence of the two problems are presented. In the absence of the conditions, by using the least-squares error criterion, an approximated CIHLQR controller is presented. It is shown that the theorems could be extended from a two-agent control system to a multi-agent system. Finally, the results are evaluated using the simulation results of a Two-Area non-reheat power system.

The problem of personal identity among others may stem from the following question—what does be the person that you are, from one day to the next, necessarily consist of? The diachronic problem of personal identity raises question on the necessary and sufficient conditions for the identity of the person over time. The synchronic problem is grounded in the question of what features or traits characterize a given person at one time. To answer these questions, John Locke discarded the soul and the body as necessary and sufficient substances for personal identity over time. He accepted consciousness as the only criterion for personal identity; the only thing capable of remaining the same and preserving personal identity through change. Though Locke’s argument is somewhat clear and coherent but what remains vague and incoherent is embedded in the question—what exactly is consciousness? How and why should it be the basis or criterion for the determination of personal identity? Using the method of critical analysis, I argue that Locke’s choice of consciousness as the determinant of personal identity, though quite novel, is incoherent and vague. Secondly, Locke had already presumed and anticipated clearly though fallaciously the very thing he wishes to substantiate. I therefore conclude that Locke’s argument is just another way of trying to escape but inadvertently prolonging the difficulty of apparently articulating a distinction between the psychological approach and physiological approach to the problem of personal identity. However, in my submission, I propose the concept of the “other” as alternative approach— a sort of an extrinsic-intrinsic approach to the problem of personal identity.

Gadamer considers understanding as an event which is the result of the fusion of horizon of interpreter and horizon of the text. From his point of view, understanding has a fundamental connection with the concept of horizon and in fact horizon is the central point in the process of understanding. Horizon for Nietzsche is a limiting concept which is not able to be transitive. Husserl draws his attention on developing and the opening feature of horizon. Horizon consists of all co-given that has not been given in intuition; however in percepting of an object plays a fundamental role.Like Nietzsche, Gadamer believes in the limiting role of horizon, though like Husserl believes in the possibility of development and openness of horizon. In his point of view, prejudices as internal horizon and historicity of Man as external horizon, are effective in constructing the understanding as well as limiting it.Unlike enlightenment thinkers, Gadamer not only does not consider prejudice as an obstacle of understanding but also believes that prejudice is the condition of any understanding. Understanding is historical. It is the result of effect of history on the Man. In Gadamer’s view, tradition or prejudice, history, and language are the main factors which play a role on the constitution of interpreter’s horizon and limiting his prospective.

Purpose: Due to the great damage that Corona has inflicted on the tourism industry, neglecting the future of tourism marketing can pose a serious challenge to this industry and economy and have irreparable consequences. The purpose of this study is to identify key factors, drivers and future scenarios of the tourism marketing.Method: The present study is applied-developmental in terms of purpose, descriptive-analytical in nature and mixed (qualitative-quantitative) in terms of methodology. The method of this research is scenario writing using MicMac software to identify key drivers and scenarios with Wizard scenario software.Findings: First, the future trends and meta-trends of post-corona tourism marketing were identified, of which 41 key trends and 8 meta-trends were identified. According to experts, 19 key factors in the future of tourism marketing in post- corona were identified using the cross-impact analysis and questionnaire completion. Then, using the cross-impact analysis questionnaire and with the help of the Wizard scenario software, two groups of favorable and unfavorable scenarios were identified.Conclusion: Based on the research results, there are two favorable scenarios and two unfavorable scenarios that can help marketing and tourism policy-makers and decision-makers to take into account the effective factors and scenarios proposed for proper planning of industry in the post-Corona era.

This paper considers the economic lot and delivery scheduling problem in a two-echelon supply chains, where a single supplier produces multiple components on a flexible flow line (FFL) and delivers them directly to an assembly facility (AF). The objective is to determine a cyclic schedule that minimizes the sum of transportation, setup and inventory holding costs per unit time without shortage. We have developed a new mixed zero-one nonlinear mathematical model for the problem. Due to the difficulty of obtaining the optimal solution, especially in the instances of medium and large-sized problems, two meta-heuristic algorithms (HGA and SA) are proposed and evaluated over randomly generated problems. Computational results indicate that the proposed HGA outperforms the SA algorithm with respect to both the solution quality and computation times especially in large-size problems.

In Kant and the Problem of Metaphysics (KPM), Heidegger shows how the initial image-making power of the imagination is pictorial in the pure image of time. He further clarifies the recognized link between the syntheses and the time-visualizing power of images which is pictorial formative power, which can visualize time. The three syntheses of imagination are replaced with the modes of existence of Dasein. Three kinds of photographs resemble the images produced when the transcendental imagination functions as Dasein. We can address the ways to visualize time by considering Dasein with a photographic preoccupation through 1. A possible look in the form of presentation (a photograph shows an immediate look of a house or person as intuitable this-here); 2. An immediate look of the thing, house, or deceased person, as well as a copy or its reproduction as a death mask; and, 3. The manner of contemplation of a likeness is an immediate look of a being present in the form of representation.

Considering the importance of solidarity as a theoretical and political structure and its connection with social harmony, acceptability and political legitimacy, the present research has conceptualized and formulated the problem of solidarity in the context of Iran's multi-ethnic society through the mediation of existing studies. . In the current research, the hybrid method has been used. The sample and statistical population of the research includes selected qualitative studies that have investigated the issue of solidarity and its dimensions in Iran from different aspects and perspectives in the period from 1372 to 1398. After searching in different databases, 500 related articles, books and research reports were identified and finally 54 sources were selected to perform the meta-combination method. Based on the synthesis of studies, solidarity in the multi-ethnic society of Iran has found a problematic situation. The results of the research confirm that the coordinates of solidarity in Iranian society are based on structural contexts and conditions. The main field in which the issue of solidarity in Iran should be established is the acceptance of a reality called "reliability and stability of cultural diversity". Based on the meta-combination of studies, the coordinates of solidarity in Iran's multi-ethnic society, due to "intercultural affinities", "disruption and non-inclusion in ethnic policies", "instability and imbalance of development", "inefficiency of ethnic political management" and "identification disorder". In the meantime, "cultural globalization", "taking role models from ethnic elites", "geopolitics of ethnic areas and transnational interventions" and "ethnic extension" are considered as intervening conditions. Despite the fact that ethnic and religious diversity is recognized as a central sign in the constitution, with this definition, political agents have sometimes resorted to strategies that social suffering and extroversion has formed in ethnic communities.

This paper proposes a novel relaxation technique based on the fractional representation of bilinear terms. This technique is embedded into an iterative two-step MILP-NLP algorithm based on piecewise relaxation and domain reduction strategies. To evaluate the performance of the algorithm, it is compared to the recently addressed iterative MILP-NLP algorithm based on piecewise McCormick relaxation techniques over a variety of instances. Our method is also applied to the crude oil scheduling problem as an application. The results confirm the efficiency of the proposed algorithm from both solution quality and running time

The influential physicist Richard Feynman became interested in the relationship between religion and science during a mid-career phase. He proposed that their interface was embroiled in unresolvable difficulties. He felt that science demanded an attitude of uncertainty for its claims, while religion contrarily required certain belief in its core doctrines. Though possessing several non-contradictory dimensions, Feynman felt that the nature of the truth claims of science and religion suffered from insurmountable elemental conflicts. This was by contrast to Karl Popper, the leading critical rationalist of the 20th century, who argued that there could be no tension between science and religion. This paper will argue that the ‘Feynman Problem’ is not as insoluble as it appears. Rather, several solutions exist within critical rationalism. Two will be presented-the first revolves around the conjectural basis of knowledge and is already a well characterised critical rationalist notion. The second is a novel solution based on the separate categorisation of psychological, pragmatic, and epistemological attitudes to religion and science. Karl Popper’s view of religion-science dissimilarity was a minimalist point of departure for critical rationalists, who have developed increasingly sophisticated frameworks for investigating the relationship between faith and reason. Critical rationalism represents an equally inspirational methodology for the pursuit of scientific and religious truth. Though both Feynman and Popper’s views on religion were underdeveloped, they foreshadowed the religion-science frameworks advocated by many late 20th century scientists, especially in the form of New Atheism and Gould’s NOMA theory.
