The aim of this work is to introduce a new class nano semi-open sets in topological spaces which called Sβ-open spaces. Also, we study the relationship between some types near open with class. exactly lie Sp-open and sets.

 The main objective of this paper is to assess the effects of architectural components on residential complex to achieve a desirable rate of privacy for the residents. Privacy is a process in which the transactions among individuals can be adjus‌ted by means of providing a suitable relationship between people and their built environment. In addition, since the transaction between the behavior o...

Urban open spaces are invaluable assets in maintaining ecological health in a highly developed urban matrix. Unfortunately, habitat values and ecological quality of these areas are often challenged by consecutive urbanization. The assessment of changing structure and function of an urban open space system is crucial in maintaining livable cities. General characteristics and types of open spaces...

Modal logics and their models have been used to speak about and represent topological spaces since the 1940s [22, 23, 16, 17]. Examples include Tarski’s programme of algebraisation of topology (“of creating an algebraic apparatus for the treatment of portions of point-set topology,” to be more precise) which involved modal logic S4 [17], and the use of the extension of S4 with the universal mod...

abstract considering the dominance of public open space use, over the use of private open space of single-family housing, in large cities in iran, an important issue in programming for designing open spaces of residential complexes is to facilitate the appropriate development of the children in open spaces. the present paper attempts to provide a flexible framework for tackling the challenge of...

A well-designed open space that encourages outdoor activity and social communication is a community asset that could potentially contribute to the health of local residents and social harmony of the community. Numerous factors may influence the use of each single space and may result in a variety of visitors. Compared with previous studies that focused on accessibility, this study highlights th...

Descriptive set theory was originally developed on Polish spaces. It was later extended to $\omega$-continuous domains [Selivanov 2004] and recently to quasi-Polish spaces [de Brecht 2013]. All these spaces are countably-based. Extending descriptive set theory and its effective counterpart to general represented spaces, including non-countably-based spaces has been started in [Pauly, de Brecht ...
