The imagination and creativity of children is often puzzling to the adult mind. Pretend play and make-believe friends are often prevalent in the life of a child. Past research shows a relationship between the use of the imagination in children’s play and their social, cognitive, and emotional development. Furthermore, there are a number of gender differences in the type of imaginary play and pr...

The idea of the modern city continues to inform urban policies and practices, shaping ideas what infrastructure is how it ought work. While there has long been conflict over its meaning relevance, particularly in southern cities, alternatives remain difficult identify. In this paper, we ‘read for difference’ practices sanitation Kampala, purposefully looking evidence an alternative imaginary. W...

In this paper, we derive a negative imaginary and a strict negative imaginary lemma based on Riccati equations. The resulting negative imaginary lemma is used to solve a controller synthesis problem. For a given uncertain system, a static controller is constructed to force the system to satisfy the negative imaginary property. As a result, the closed-loop system can be guaranteed to be robustly...

The task of discriminating the motor imagery of different movements within the same limb using electroencephalography (EEG) signals is challenging because these imaginary movements have close spatial representations on the motor cortex area. There is, however, a pressing need to succeed in this task. The reason is that the ability to classify different same-limb imaginary movements could increa...

Imaginary cubes are three dimensional objects which have square silhouette projections in three orthogonal ways just as a cube has. In this paper, we study imaginary cubes and present assembly puzzles based on them. We show that there are 16 equivalence classes of minimal convex imaginary cubes, among whose representatives are a hexagonal bipyramid imaginary cube and a triangular antiprism imag...

The atmospheric refractive index consists of both real and imaginary parts. The intensity of refractive index fluctuations is generally expressed as the refractive index structure parameter, with the real part reflecting the strength of atmospheric turbulence and the imaginary part reflecting absorption in the light path. A large aperture scintillometer (LAS) is often used to measure the struct...

The ongoing Russian-Ukrainian conflict, crises in the European Union (EU), and armed conflicts EU neighbourhood have influenced prospects of future development eastern central Europe. A search for new security architecture on margins regional collaborations that prevail across formal borders forced national elites Poland Ukraine to redefine their efforts regarding co-operation. Rationales joini...
