Abstract It is known that during operation, the aircraft construction materials are exposed to significant mechanical loads and changes in temperature for a very short period of time. All this leads various defects damages assemblies units need be inspected safe operation aircraft, their assemblies, units. In some cases, implementation inspection or diagnostic accompanied by emergence technical...

Introduction: Educational justice is a process by which all those involvedin education are pondering and seeking to establish it in their regulatoryenvironments. This study aimed to investigate effective factors in an idealeducational justice and the current condition of educational justice from thestudents’ viewpoint and ultimately increase the awareness and understandingof authorities and edu...

A group of sinusoidally-wound coaxial toroidal coils can be used to determine the transverse distribution of a time-dependent current through their common aperture. The current is expressed in a basis of chapeau (pulse) functions over an array of pixels, and matrix methods are used to calculate the current in each pixel from the voltages induced on the coils. Optimum configurations of pixels ar...

Current theories of cognitive developmental debate the extent to which children’s cognition depends on a priori conceptual knowledge. The current set of experiments explores this debate in the domain of causal reasoning: To what degree do preschoolers rely on knowledge about causal relations vs. attention to temporal structure? In three experiments, causal structure and temporal order were eith...

Planar intra-cortical electrode (Utah) arrays provide a unique window into the spatial organization of cortical activity. Reconstruction of the current source density (CSD) underlying such recordings, however, requires "inverting" Poisson's equation. For inter-laminar recordings, this is commonly done by the CSD method, which consists in taking the second-order spatial derivative of the recorde...
