Background: Social networking has a dramatically increasing trend among adolescents. By creating novel models of content production, distribution, and reception, this space has introduced opportunities and threats for adolescents, which must be understood in relation with their health status. This study was conducted with the aim of describing the psychosocial experiences of Iranian adolescents...

If autonomous agents like humans and robots act in physical space, several types of conflicts can occur that result from the fact that actions occupy space. To avoid such conflicts, social robots must have the capacity to consider the actions taken by other robots and by humans. This thesis proposes a conceptual framework which can be used to specify knowledge about spatial needs of activities ...

design of the new apartment buildings in iran, has been faced to a decline of quality of local life and an improper interaction between inside-outside of residential spaces. this interaction can be affected by the quality of in-between spaces in different scales of apartment buildings in residential developments. in-between spaces of apartment houses refer to a hierarchy of the main entrance, o...

Nowadays space is considered to be a net of connections between different areas. The questions how to delineate its character and how it is possible to objectively compare two spaces is a matter under consideration. This was the reason for creating new theories about the structure of space. Space syntax analysis (SSA) or simply Space Syntax defines a number of theories and research areas devo...

Some inequalities of the Slater type for convex functions of selfad-joint operators in Hilbert spaces H under suitable assumptions for the involved operators are given. Amongst others, it is shown that if A is a positive definite operator with Sp (A) ⊂ [m, M ] and f is convex and has a continuous derivative on [m, M ] , then for any x ∈ H with x = 1 the following inequality holds: 0 ≤ f Af ′ (A...

This paper presents an on-the-fly uniformization technique for the analysis of time-inhomogeneous Markov population models. This technique is applicable to models with infinite state spaces and unbounded rates, which are, for instance, encountered in the realm of biochemical reaction networks. To deal with the infinite state space, we dynamically maintain a finite subset of the states where mos...
