In this paper, we deal with a simple geometric problem: Is it possible to partition rectangle into k non-congruent rectangles of equal area? This problem is motivated by the so-called ‘Mondrian art problem’ that asks similar question for dissections integer sides. Here, generalize Mondrian allowing real case, show minimum value have ‘perfect partition’ (that is, equal-area rectangles) seven. Mo...

Abstract Justice has always been a controversial issue and it is difficult to agree on its definition and dimensions. According to some experts, in order to establish justice a criterion should be defined for each blessing, gift or each area and transportation can be considered as one of these areas. In this study, in order to investigate the justice status in the distribution of urban tr...

Transferring a huge amount of data between different network locations over the network links depends on the network's traffic capacity and data rate. Traditionally, a mobile device may be moved to achieve the operations of vertical handover, considering only one criterion, that is the Received Signal Strength (RSS). The use of a single criterion may cause service interruption, an unbalanced ne...

One criterion recommended (1,2) for establishing the maximal allowable imprecision is derived from the biological variability data. According to this criterion, the metrological coefficient of variation must be equal to or less than one-half of the within-subject biological coefficient of variation. When information about biological variability is not available, or when current procedures give ...

This paper proposes a new system-level application for monitoring out-of-step (OOS) events in power systems. As already known, amplitude-dependent frequency shift is nonlinear phenomenon of electromechanical oscillations under large disturbances. The indicates the system’s nearness to instability. tool utilizes Normal Form method identify named phenomenon, leading accelerated OOS detection. pro...

This paper suggests an optimization-based methodology for the design of minimum weight structures with kinematic nonlinear behavior. Attention is focused on three-dimensional reticulated structures idealized with beam elements under proportional static loadings. The algorithm used for optimization is based on a classical optimality criterion approach using an active-set strategy for extreme lim...
