In this paper, we aim to monitor the flow of people in large public infrastructures. We propose an unsupervised methodology to cluster people flow patterns into the most typical and meaningful configurations. By processing 3D images from a network of depth cameras, we built a descriptor for the flow pattern. We define a data-irregularity measure that assesses how well each descriptor fits a dat...

Knowledge related aspects of businesses processes are often ignored or referred to as a black box in process improvement projects. As a result they remain untouched and it is left to the knowledge workers to establish routines and workflows that deliver results needed to fulfill the business processes needs. This often results in lowered efficiency, redundancy of knowledge related activities, l...

In this paper we propose a head detection method using range data from a stereo camera. The method is based on a technique that has been introduced in the domain of voxel data. For application in stereo cameras, the technique is extended (1) to be applicable to stereo data, and (2) to be robust with regard to noise and variation in environmental settings. The method consists of foreground selec...

sepahan is a new bread wheat cultivar derived from progenies of a cross made between azadi cultivar and some high yielding and resistant to rust advanced lines. all selections were made in kelardasht and iranshahr stations and early evaluations in karaj. it was also studied in regional uniform yield trials in moderate stations including kaboutar abad. results revealed that this line is more tol...

in this paper we present the problem of designing a three level hub center network. in our network, the top level consists of a complete network where a direct link is between all central hubs.  the second and third levels consist of star networks that connect the hubs to central hubs and the demand nodes to hubs and thus to central hubs, respectively. we model this problem in an incomplete net...

People were given highly constrained low budgets of mate dollars to allocate across various characteristics pertaining to their ideal partners and to their ideal selves for longand short-term mating. First, results replicated findings from Li et al. (2002) and Li & Kenrick (2006). For ideal long-term mates, men prioritized physical attractiveness and women prioritized social status. For ideal s...

The U.S. military, despite spending over $13 billion, appears powerless to stop the Iraqi insurgency’s improvised explosive devices (IEDs), which cause most of the military’s casualties and prevent victory by showing lawlessness and insecurity. However, this view ignores substitution effects we consider here. Using rational choice and expectations models, we find a backward-bending supply curve...

Despite the abundance of research linking frustration with prejudice, no research has examined the moderating role of personality. Two studies tested the prediction that narcissism would moderate the link between frustration and prejudice against immigrants in that individuals high in narcissism would show a stronger association than others. In Study 1 (n = 156), participants completed online s...

We demonstrate that the agrarian unrest in the United States between 1870 and 1900 can be given an economic explanation, despite its association with increases in the real price of agricultural produce. It was not merely the result of nominal illusions as other scholars have suggested. Falling transportation costs allowed for the extension of the frontier and for more farmers to enter the inter...
