A new type of high-energy binary system has been revealed by the INTEGRAL satellite. These sources are being unveiled by means of multi-wavelength optical, nearand midinfrared observations. Among these sources, two distinct classes are appearing: the first one is constituted of intrinsically obscured high-energy sources, of which IGR J16318-4848 seems to be the most extreme example. The second ...

Classes of coordinate-invariant omnibus goodness-of-fit tests on compact Riemannian manifolds are proposed. The tests are based on Giné's Sobolev tests of uniformity. A condition for consistency is given. The tests are illustrated by an example on the rotation group SO(3). 1. Introduction. Although many tests of goodness of fit are available for distributions on the circle, comparatively little...

Path planning was finished by employing classical Dijkstra algorithm and the controller of the quadrotor adopted integral backstepping method. In orde...

Abstract Stream Control Transmission Protocol (SCTP) exploits multiple network interfaces to provide multi-streaming and data chunk ordering in a stream. An extended feature of SCTP, i.e., Concurrent Multi-path Transfer (CMT), bids concurrent transmission multi-path transfer environment guarantees bandwidth aggregation, load sharing, robustness, reliability. In such an environment, the paths us...

Guy proved his conjecture for all n ≤ 10. This was later extended by Pan and Richter in [3] to n ≤ 12. For general n, the most that is known is that 0.8594Z(n) ≤ cr(Kn) ≤ Z(n). The lower bound was proved by de Klerk et al. in [2]. The upper bound can be obtained in a number of ways, one of which we present here. Draw the Kn on the double cover of a disc, glued along the boundary, which is of co...

In this paper we briefly discuss the ways in which angular momentum transport is included in simulations of non-self-gravitating accretion disks, concentrating on disks in close binaries. Numerical approaches fall in two basic categories; particle based Lagrangian schemes, and grid based Eulerian techniques. Underlying the choice of numerical technique are assumptions that are made about disk p...

Due to the ever-increasing number of computer nodes in distributed systems, efficient and effective tools have become crucial for their analysis. Although several methods been proposed monitor profile tracing remains most solution in-depth system Tracing is act collecting a trace, which sequence low-level events generated by kernel or userspace. After data collection, important part event The p...

Abstract. This paper describes a new global dataset of cloud properties observed by MODIS relying on the current (collection 6.1) processing data and produced to facilitate comparison with results from observational proxy used in climate models. The merges observations two instruments into single netCDF file. Statistics (mean, standard deviation, number observations) are accumulated over daily ...

Query and transformation languages developed since the mid 90es for XML and semistructured data – e.g. XQuery, the precursors of XQuery, and XSLT – built upon a path-oriented node selection: A node in a data item is specified in terms of a root-to-node path in the manner of the file selection languages of operating systems. Constructs from regular expressions such as ∗, +, ?, and “wildcards” gi...
