This paper describes a novel lane detection algorithm for visual traffic surveillance applications under the auspice of intelligent transportation systems. Traditional lane detection methods for vehicle navigation typically use spatial masks to isolate instantaneous lane information from on-vehicle camera images. When surveillance is concerned, complete lane and multiple lane information is ess...

The growing popularity of Agile methods motivates our interest in its value foundations, publicized in information technology (IT) community discourse. IT community discourses provide key functions of interpretation, legitimization and mobilization. Conceptualized as organizing visions, these community discourses provide knowledge about how an IT innovation, such as Agile, should be applied in ...

Let M be a matroid without loops or coloops and let TM be its Tutte polynomial. In 1999 Merino and Welsh conjectured that max(TM (2, 0), TM (0, 2)) ≥ TM (1, 1) for graphic matroids. Ten years later, Conde and Merino proposed a multiplicative version of the conjecture which implies the original one. In this paper we show the validity of the multiplicative conjecture when M is a lattice path matr...

We prove a general duality theorem for width parameters in combinatorial structures such as graphs and matroids. It implies the classical such theorems for path-width, tree-width, branch-width and rank-width, and gives rise to new width parameters with associated duality theorems. The dense substructures witnessing large width are presented in a unified way akin to tangles, as orientations of s...

Given an underlying undirected simple graph, we consider the set of all acyclic orientations of its edges. Each of these orientations induces a partial order on the vertices of our graph and, therefore, we can count the number of linear extensions of these posets. We want to know which choice of orientation maximizes the number of linear extensions of the corresponding poset, and this problem w...

This paper seeks to extend the literature on inequalities and exclusion in the night-time economy through a rhythmic analysis of visitor presence in public space in nightlife districts in the city-centres of the Dutch cities of Groningen, Utrecht and Rotterdam. We demonstrate substantial inequalities in visitor presence based on race/ethnicity and gender. In the cities considered racial/ethnic ...

ABSTRACT This paper provides a review of Benjamin Mendelsohnvs delineation of a typology of criminal victims. The typology consists of six categories: (1) completely innocent victims; (2) victims with minor guilt; (3) voluntary victims; (4) victims more guilty than the offender; (5) victims who alone are guilty; and (6) the imaginary victims. It is noted by the author that of the six categories...

The apparent spatial orientation of an object can differ from its physical orientation when differently oriented objects surround it. This is the "tilt illusion". Previously [Solomon, J. A., & Morgan, M. J. (2006). Stochastic re-calibration: Contextual effects on perceived tilt. Proceedings of the Royal Society of London. Series B, Biological Sciences, 273, 2681-2686], we reported a loss of ori...

Abstract Nonprofit firms can be multi-stakeholder organizations, in which employees, clients, volunteers, public institutions, and funders have formal or informal power to affect corporate strategy. This paper focuses on nonprofit firms’ orientation toward clients investigates its role shaping capital structure. We first develop a theoretical framework derive conditions under the relationship b...

one of the main branches of entrepreneurship is entrepreneurial orientation as it certainly plays an important role in the success and growth of the organizations. entrepreneurial orientation is rooted in adopting a strategy. many organizational policies which are formulated for the development of entrepreneurship are associated with information and communication technologies, in the other hand...
