If uniform coding (Gödelization) of potentially infinite sequences of numbers can be performed in PSPACEF, then PSPACE = EXPTIME 6= EXPSPACE = 2-EXPTIME, and, for all p, we have p−EXPSPACE = p+1-EXPTIME; if it can be performed in LINSPACEF, we also have LINSPACE = DTIME(2); the proof fails, when relativized to oracle-TM’s. A by-product of this research is that PTIMEF is not closed under number-...

Grapheme-color synesthesia is a neurological phenomenon in which letters and numbers (graphemes) consistently evoke particular colors (e.g., A may be experienced as red). These sensations are thought to arise through the cross-activation of grapheme processing regions in the fusiform gyrus and color area V4, supported by anatomical and functional imaging. However, the developmental onset of gra...

Motivated by the problem of allocating optical bandwidth in tree–shaped WDM networks, we study the fractional path coloring problem in trees. We consider the class of locally-symmetric sets of paths on binary trees and prove that any such set of paths has a fractional coloring of cost at most 1.367L, where L denotes the load of the set of paths. Using this result, we obtain a randomized algorit...

Electrochemical properties of various rock-shaped-CuO/graphite (G) composites and monoclinic structure CuO nanoparticles as the cathode versus a zinc plate as the anode in a 4M NaOH electrolyte were elucidated by electrochemical impedance spectroscopy (EIS) and chronopotentiometry (CP) in a two electrode configuration cell. Various values of G 9, 16 and 28 wt% were prepared and studied as catho...

A retrospective evaluation of attitudinal, behavioural and knowledge change among diverse stakeholder groups was conducted in Limpopo Province of South Africa to assess the effectiveness of a series of values clarification (VC) interventions. Telephone and face-to-face interview (193) results revealed that over two-thirds (70.2%) reported behavioural changes and 93.2% reported increased compass...

the foundation of most intellectual discourse is western-centric to the exclusion of other views. this includes ideal patterns of social interaction, preference for aesthetic, accepted norms and values, and the concepts of dignity, respectability, morality and ethics. such a position is culturally myopic. western cultural influence colors all of them including moral precepts. the assumption is ...

Proceedings of the 1998 IEEE International Conference on Computer Vision, Bombay, India Bilateral filtering smooths images while preserving edges, by means of a nonlinear combination of nearby image values. The method is noniterative, local, and simple. It combines gray levels or colors based on both their geometric closeness and their photometric similarity, and prefers near values to distant ...

This work presents the application of a comprehensive modeling framework that can help optimize design multi-layered optical filters for coloring photovoltaic (PV) modules based on crystalline silicon solar cells. To overcome technical issues related to implementation color PV modules, like glare and instability, we have extensively deployed colorimetry metrics, such as Hue, Chroma, Luminance (...
