We present the measurement of the the flux and angular distribution of atmospheric νµ using the MACRO detector. Three different event topologies are detected in two different energy ranges. High energy neutrinos (Eν ∼ 80 GeV) via the identification of upward throughgoing muons. Lower energy neutrinos (Eν ∼ 4 GeV) via the upgoing stopping and partially contained downgoing muons (ID+UGS), or via ...

Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...

The flux of low energy atmospheric neutrinos (Eν ∼ 4 GeV ) has been studied with the MACRO detector at Gran Sasso by detecting νμ interactions inside the apparatus, and by upward-going stopping muons. The updated analysis of the data collected until now with the complete apparatus will be presented. The results show a deficit of the measured number of events in an uniform way over the whole zen...

In this paper, we investigate area requirements for drawing s-t hierarchically planar graphs by straight-lines. Two drawing standards will be discussed: 1) each vertex is represented by a point and 2) grid visibifity representation (that is, a line segment is allowed to represent a vertex). For the first drawing standard, we show an exponential area lower bound needed for drawing hierarchically...

A small subset of neutrino-induced upward going muons in the SuperKamiokande detector consists of high energy muons that undergo radiative energy losses through bremsstrahlung, pair production and photo-nuclear interactions. The mean energy of the parent neutrinos of these showering upward muons is approximately 1 TeV, allowing the selection of a high energy sample of neutrinos. We present the ...

We study planar drawings of directed graphs in the L-drawing standard. We provide necessary conditions for the existence of these drawings and show that testing for the existence of a planar L-drawing is an NP-complete problem. Motivated by this result, we focus on upwardplanar L-drawings. We show that directed st-graphs admitting an upward(resp. upward-rightward-) planar L-drawing are exactly ...
