Time has become an integral part of our understanding of the context of organizations, particularly as the pace of change in business models continues to mirror the relatively fast evolution of technology. The importance of time is particularly magnified in the social context of organizational creativity, as innovation has become the key strategic orientation of organizations attempting to achi...

In this paper we consider spatial problems modeled by a Gaussian random field prior density and a nonlinear likelihood function linking the hidden variables to the observed data. We define a directional block Metropolis–Hastings algorithm to explore the posterior density. The method is applied to seismic data from the North Sea. Based on our results we believe it is important to assess the actu...

Clustering categorical data is an integral part of data mining and has attracted much attention recently. In this paper, we present k-histogram, a new efficient algorithm for clustering categorical data. The k-histogram algorithm extends the k-means algorithm to categorical domain by replacing the means of clusters with histograms, and dynamically updates histograms in the clustering process. E...

The paper deals with a non-conforming nite element method on a class of anisotropic meshes. The Crouzeix-Raviart element is used on triangles and tetrahedra. For rectangles and prismatic (pentahedral) elements a novel set of trial functions is proposed. Anisotropic local interpolation error estimates are derived for all these types of element and for functions from classical and weighted Sobole...

The aim of the paper is to analyze the characteristics of winter fog in terms of its trend and spatial-temporal variability over Indo-Gangetic plains. The study reveals that during last four and half decades (1971-2015), an alarming increasing trend in fog frequency has been observed during the winter months of December and January over the study area. The frequency of fog has increased by 118....

We present a denotational semantics for an Algol-like language Alg, which is fully abstract for the second order subset of Alg. This constitutes the rst signiicant full abstraction result for a block structured language with local variables. As all the published`test equivalences' 13, 8, 23] for Algol-like languages are contained in the second order subset, they can all be validated (easily) in...

background: airport workers are continuously exposed to different levels of radiofrequency microwave (rf/mw) radiation emitted by radar equipments. radars are extensively used in military and aviation industries. over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile ...
