This paper proposes a novel system for managing visual attention in social robots. This system is based on a client/server approach that allows integration with a cognitive architecture controlling the robot. The core of this architecture is a distributed knowledge graph, in which the perceptual needs are expressed by the presence of arcs to stimuli that need to be perceived. The attention server sends motion commands to the actuators of the robot, while the attention clients send requests through the common knowledge representation. The common knowledge graph is shared by all levels of the architecture. This system has been implemented on ROS and tested on a social robot to verify the validity of the approach and was used to solve the tests proposed in RoboCup @ Home and SciROc robotic competitions. The tests have been used to quantitatively compare the proposal to traditional visual attention mechanisms.

We investigate the variant of epistemic logic S5 for reasoning about knowledge under hypotheses. The logic is equipped with a modal operator of necessity that can be parameterized with a hypothesis representing background assumptions. The modal operator can be described as relative necessity and the resulting logic turns out to be a variant of Chellas’ Conditional Logic. We present an axiomatization of the logic and its extension with the common knowledge operator and distributed knowledge operator. We show that the logics are decidable, complete w.r.t. Kripke as well as topological structures. The topological completeness results are obtained by utilizing the Alexandroff connection between preorders and Alexandroff spaces.

<p><strong>Abstract.</strong> A cultural region could be only a choronym in the common knowledge. This choronym is applied with different intensity to different geographic locations. In the core a lot of criterion is present, in periphery they may be missing. The cultural criteria can be transformed to Boolean indicators, so we can understand the phenomenon as a 3D statistical surface.</p><p>We analyze the case of Székely Land. The Székelys are a subgroup of Hungarians, who use the Hungarian language; they live in Romania. The Székely seats were administrative regions from approx. 1300 until 1876: in Hungary, later in Transylvania and in the Habsburg Empire. After the dissolution of the seats, the area of the former seats was part of Austria–Hungary and after 1918 (mostly) of Romania. Since 1876 several administrative reorganizations touched the region. The Székely population at censuses professes itself ethnically and linguistically as Hungarian. The choronym is applied to a cultural region, where a set of similar characteristics occurs all over this region, but the boundaries of these characteristics are different. The perception of Székely Land has adapted to these administrative or ethnographic– linguistic factors, its former historical borders became fading.</p><p>The author compiled 6 criteria (2 historic, 2 administrative and 2 linguistic one) to define the core and periphery of the area to which is applied this choronym. The paper summarizes the local intensity of these criteria on choropleth map, this thematic map shows the core and periphery of the area applied to the choronym of Székely Land.<p>

RESUMENEl sistema patriarcal no afecta exclusivamente al poder político y judicial, sino que afecta a la estructura interna de la sociedad, la identidad y las formas de vida de los individuos que en ella viven. Para comprender mejor como condiciona el sistema patriarcal las formas de vida y la visión que tienen los individuos de la realidad social, hemos de analizar el modo en que se extiende al orden institucional y lo determina mediante "tipificaciones" de hechos y de personas y mediante roles concretos, esteoreotipaciones sexiuales que obstaculizan el acceso a la esfera pública de la mujer, así como su reinserción en el mercado laboral, en suma, todo aquello que afecta al conocimiento común que comparten los miembros de una comunidad. El cambio hacia una mayor igualdad y una real democracia paritaria y compartida no es posible sin una paulatina educación y concienciación de la sociedad en su conjunto.PALABRAS CLAVEPATRIARCADO-TIPIFICACIÓN SOCIAL-IGUALDAD DE GÉNEROABSTRACTPatriarchalism is not only present in politics and the judicial system. It also affects the internal structure of society, above all the life and identitý of individuals. To understand better how it conditions their ways of life and the vision the individuals have of social reality, we should study how patriarchalism r3eaches the system of institutions and how this becomes determined by "typifications" of facts and people, and by certain roles or sexual stereotypes that hinder the access of women both to the public sphere and to tha labor market. It sum, everything that concerns the common knowledge that the members of a community share. The move towards more equality and towards a more egalitarian democracy heavily depends on the spread of civic education to the entire society.KEYWORDSPATRIARCHALISM-SOCIAL TYPIFICATION-GENDER EQUALITY

The core principles in Ayurveda give prime importance to Agni, Prakriti, Ahara (food) and Vihara (lifestyle) in maintaining health. Present era people are scheduled to one or the other works due to which they are following unrightful food and habits which lead the manifestation of one of the common disorder which troubles person a lot - Amlapitta. By excess “Hurry, Worry and Curry” GIT disorders are the most common, not only affecting physical health but also psychological and social health. Amlapitta is one of that and it is a burning problem of the whole World. Amalpitta is composed of word Amla and Pitta. Amlapitta is a very common disease caused by Vidagdha Pitta with features like Amlodgara, Tiktodgara, Hrit, Kantha Daha etc. Pathya recommended in Amlapitta are Yava, Godhuma, Purana Shali, Mudga Yusha, Lajasaktu etc. Apathya recommended in Amlapitta are Navanna, Avidugdha, Masha, Kulattha, Dadhi and etc. So this present review article throws light on Pathya (conducive) and Apathya (non conducive) in Amlapitta.

This article is organized around logicism's answers to the following questions: What is the basis for our knowledge of the infinity of the numbers? How is arithmetic applicable to reality? Why is reasoning by induction justified? Although there are, as is seen in this article, important differences, the common thread that runs through all three of the authors discussed in this article their opposition to the Kantian thesis that reflection on reasoning with mere concepts (i.e., without attention to intuitions formed a priori) can never succeed in providing satisfactory answers to these three questions. This description of the core of the view differs from more usual formulations which represent the opposition to Kant as an opposition to the contention that mathematics in general, and arithmetic in particular, are synthetic a priori rather than analytic.

A new scan-head structure for the scanning tunneling microscope (STM) is proposed, featuring high scan precision and rigidity. The core structure consists of a piezoelectric tube scanner of quadrant type (for XY scans) coaxially housed in a piezoelectric tube with single inner and outer electrodes (for Z scan). They are fixed at one end (called common end). A hollow tantalum shaft is coaxially housed in the XY-scan tube and they are mutually fixed at both ends. When the XY scanner scans, its free end will bring the shaft to scan and the tip which is coaxially inserted in the shaft at the common end will scan a smaller area if the tip protrudes short enough from the common end. The decoupled XY and Z scans are desired for less image distortion and the mechanically reduced scan range has the superiority of reducing the impact of the background electronic noise on the scanner and enhancing the tip positioning precision. High quality atomic resolution images are also shown.

The paper presents the interdisciplinary analysis of the determinants of the system of self-communication discourse and internal dialogue as the forms of objectivation of human mental content focused on some actions for meeting some objectives. The author describes discourse as integration of communication and language processes in self-understanding and personal identity. Contextually determined and dynamic self-communication discourse, as a way of acquirement of new senses and confirmation of old ones, verbalizes current personal values. The study results reveal the characteristics and relations of the internal dialogue discourse determinants within the human objectivity–subjectivity continuum. Discourse determinants prescribe its context and rules and include the prototype place and agents with their motives and objectives. Self-positions manifested in Self and Non-Self (Other Self) binary self-predications form the core pair of agents. The modality of a person’s attitude to own Self-positions makes their communications a dialogue or a monologue on the boundary of their sub-territories as a discourse prototype place. The degree of discourse agency, its closeness within the prototype place, or transgression openness depends on the complexity and differentiation of Self-concept and ego boundaries functionality. The frustration of meta-necessity to keep self-confidence and self-acceptance by reassessment and reformation of interrelations of Self-positions determines the motives and objectives of self-communication. The common goal of self-organization is implemented through the internal dialogue in the form of institutionalization, verification, and integration of their Self-predications. Status-role characteristics of agents and functionality of discourse prototype place determine the specificity of its motives and objectives according to the systemic effects of Self-organization.
