This paper is based on a theory being developed in collaboration with Seymour Papert [Note 1] in which we v i e w t h e m i n d a s a n o r g a n i z e d s o c i e t y o f intercommunicating "agents". Each such agent is, by itself, very simple. The subject of this paper is how that simplicity affects communication between different parts of a single mind and, indirectly, how it may affect inter...

As for serial code on CPUs, parallel code on GPUs for dense polynomial arithmetic relies on a combination of asymptotically fast and plain algorithms. Those are employed for data of large and small size, respectively. Parallelizing both types of algorithms is required in order to achieve peak performances. In this paper, we show that the plain dense polynomial multiplication can be efficiently ...

introduction: among the environmental pollutions, noise is very important for its physiological  and psychological effects on human. traffic noise is one of the most important pollutants and the  hospitals  are  one  of  the  critical  places  regarding  this  type  of  noise.  for  these  reasons,  in  the  summer  of  1382,  the  traffic  noise  of  mashhad  main  streets  around  the  hospit...

this paper deals with the concentration variation of cd, as, pb and no3- in groundwater of anar plain located in sw iran (west of kerman province). for this purpose, 21 samples were taken in april 2009 from discharging wells across the plain and after analysis and control of their results, isoconcentration maps and related graphs were prepared and interpreted. accordingly, the concentration of ...

The Front Cover illustrates the application of ion-exchanged zeolites for hydrogen storage in fuel cell vehicles. different zoom levels show molecule adsorbed on extra-framework cations (Cu+, Co2+, or Ni2+) CHA and AEI frameworks. Different detail also represent our atomic level understanding solution to a macro problem. design by Olus Ozbek. More information can be found Research Article Ozbek...

BACKGROUND Plain radiographic assessment of posterolateral fusion has been reported as accurate in only two thirds of patients who were found to be healed at surgical exploration. Plain radiographic techniques for fusion assessment of interbody fusion with radiolucent cages are reported to be accurate. A helical computed tomography (CT) scan shows a high sensitivity for pseudarthrosis compared ...

archaeological excavations on the western part of the central iranian plateau, known as the qazvin plain provides invaluable information about the sedentary communities from early occupation to the later prehistoric era. despite the past archeological data, chronological studies mostly rely on the relative use of the bayesian modeling for stratigraphically-related radiocarbon dates. the current...
