In this paper we propose a novel texture recognition feature called Fractal Weighted Local Binary Pattern (FWLBP). It has been observed that fractal dimension (FD) measure is relatively invariant to scale-changes, and presents a good correlation with human perception of surface roughness. We have utilized this property to construct a scale-invariant descriptor. We have sampled the input image u...

BACKGROUND Workforce and leadership development are central to the future of public health. However, public health has been slow to translate and apply leadership models from other professions and to incorporate local perspectives in understanding public health leadership. PURPOSE This study utilized the full-range leadership model in order to examine public health leadership. Specifically, i...

Deneubourg et al. 1] introduced a model of sorting behavior in ants. They found that simple model ants were able to sort into piles objects initially strewn randomly across the plane. The model is in qualitative agreement with the behavior of real ants. The model ants operate according to local strategic rules and possess only local perceptual capacities. Nonetheless, they are able to impose gl...

The majority of structural health monitoring methods are based on detecting changes in the modal properties, which are global characteristics of the structure, and are not sensitive to local damage. Wave travel times between selected sections of a structure, on the other hand, are local characteristics, and are potentially more sensitive to local damage. In this paper, a structural health monit...

Two key issues in local search algorithms are the definition of a neighborhood and the way to examine it. In this chapter we consider techniques for examining very large neighborhoods, in particular, ways for exactly searching them. We first illustrate such techniques using three paradigmatic examples. In the largest part of the chapter, we focus on the development and experimental study of ver...

The Cuachy problem for the 3D vortical flow of ideal barotropic fluid is considered. It is shown that the solution of the Cauchy problem is unique, if one considers seven dynamic equations for seven dependent variables: the density ρ, the velocity v and Lagrangian variables ξ = {ξ 1 , ξ 2 , ξ 3 }, labeling the fluid particles. If one considers only the closed (Euler) system of four equations fo...

Local health department directors' intent on getting their organizations ready for accreditation must embrace the blurring of leader/follower lines and create an accreditation readiness team fueled not by traditional leader or follower roles but by teamship.

The LBP scale space serves as a shape representation, which thus allows not only for shape classification but also for an (approximate) reconstruction of the original shape. In this paper possible LBP scale space origins within a shape are evaluated. The influence of the LBP scale space center on the reconstruction quality is studied by computing the LBP scale space for every position inside a ...

This paper describes extensions to an evolutionary algorithm that timetables classes for an entire University. A new method of dealing with multi-objectives is described along with a user interface designed for it. New results are given concerning repair of poor recombination choices during local search. New methods are described and evaluated that allow timetables to be produced which have min...

We introduce two practical properties of hierarchical clustering methods for (possibly asymmetric) network data: excisiveness and linear scale preservation. The latter enforces imperviousness to change in units of measure whereas the former ensures local consistency of the clustering outcome. Algorithmically, excisiveness implies that we can reduce computational complexity by only clustering a ...
