Purpose: We propose in this paper to analyze what are the factors that influence knowledge transfer both intra and intergenerational in family firms. The main objective is to establish a framework that can be used later in empirical research, although we maintain a completely theoretical approach in this paper Design/methodology/approach: This study, which is a comprehensive framework character...

A functional approach for the study of the random walks in random sceneries (RWRS) is proposed. Under fairly general assumptions on the random walk and on the random scenery, functional limit theorems are proved. The method allows to study separately the convergence of the walk and of the scenery: on the one hand, a general criterion for the convergence of the local time of the walk is provided...

This paper firstly presents an approach of parallel coordinates based parameter control panel (PCP). The PCP is used to control parameters of focal region-based volume rendering (FRVR) during data analysis. It uses a parallel coordinates style interface. Different rendering parameters represented with nodes on each axis, and renditions based on related parameters are connected using polylines t...

For Laplace’s equation, we discuss whether it is possible to construct a linear positive finite volume (FV) scheme on arbitrary unstructured grids. Dealing with the arbitrary grids, we state a control volume which guarantees a positive FV scheme with linear reconstruction of the solution. The control volume is defined by a property of the analytical solution to the equation and does not depend ...

In this paper we introduce a novel approach to control different rendering parameters of volume ray casting. Since the introduction of ray casting implementations on programmable graphics hardware, both performance and flexibility have increased and are able to outperform texture-based techniques. In addition, by using rays for computing the volume integral instead of proxy geometry one has mor...

background: leishmaniasis is an obligate intercellular protozoon that affects animals and human. it has zoonosis and/or anthroponosis transmission. human and veterinary medicine, environmental science and wildlife conservation special­ists have many commonalities in case of visceral leishmaniasis. still the above disciplines respond against leishmaniasis in a separate way.   the aim of this re­...
