In this paper, we propose a cooperative energy-efficient localization framework (CELF) for power saving in vehicular long-thin networks (VLTNs) with fleet cyclists using smart phones along a common cycling route. As cyclists upload their position data and download global fleet information, all power-consuming GPS receivers have to be turned on for obtaining their current locations. To minimize ...

In this paper we propose an algorithm for the minimization of potential energy functions. The new algorithm is based on the differential evolution algorithm of Storn and Price [1]. The algorithm is tested on two different potential energy functions. The first function is the Lennard Jones energy function and the second function is the many-body potential energy function of Tersoff [2, 3]. The f...

Many methods have been proposed to solve the problems of recovering intrinsic scene properties such as shape, reflectance and illumination from a single image, and object class segmentation separately. While these two problems are mutually informative, in the past not many papers have addressed this topic. In this work we explore such joint estimation of intrinsic scene properties recovered fro...

Difference-of-Convex (DC) minimization, referring to the problem of minimizing difference two convex functions, has been found rich applications in statistical learning and studied extensively for decades. However, existing methods are primarily based on multi-stage relaxation, only leading weak optimality critical points. This paper proposes a coordinate descent method class DC functions seque...
