This paper presents a randomized incremental algorithm for computing a single face in an arrangement of n line segments in the plane that is fairly simple to implement. The expected running time of the algorithm is O (not (n) log n). The analysis of the algorithm uses a novel approach that generalizes and extends the Clarkson-Shor analysis technique [in Discrete Comput. Geom., 4 (1989), pp. 387...

Abstract This essay aims to explore flexible work in the context of capitalism propose a theoretical-analytical model different classifications this phenomenon. From critical literature review, we present fundamental problems - understanding multiple manifestations flexibility and how they affect workers their productive practices. The proposed comprises three interdependent analytical levels: ...

This paper deals with the proposition of a prognostic approach that enables to face up to the problem of lack of information and missing prior knowledge. Developments rely on the assumption that real data can be gathered from the system (online). The approach consists in three phases. An information theory-based criterion is first used to isolate the most useful observations with regards to the...

We extend vector configurations to more general objects that have nicer combinatorial and topological properties, called weighted pseudosphere arrangements. These are defined as a variant of arrangements pseudospheres, in the representation theorem for oriented matroids. show rank 3, real Stiefel manifold, Grassmannian, Grassmannian homotopy equivalent analogously spaces As consequence, this gi...

terrorism is not a new phenomenon. history is full of terrorist acts which have taken or threaten many innocent people lives. increasing terrorist acts led the international community to expand its arrangements against them. consequently, approval of 12 world conventions and 7 regional ones is in parallel with the arrangements. through the un security council's resolution no. 1373 after 9/...

Data envelopment analysis (DEA) is non-parametric linear programming (LP) based technique for estimating the relative efficiency of different decision making units (DMUs) assessing the homogeneous type of multiple-inputs and multiple-outputs. The procedure does not require a priori knowledge of weights, while the main concern of this non-parametric technique is to estimate the optimal weights o...
