national health information network (nhin) is a network in which all health care organizations, government agencies and other health-related organizations are connected to each other to exchange information about health. due to the necessity of a framework for nhin development, in this paper, according to the literature review, a definition for nhin framework was provided, and then the nhin rel...

Play and Game are considered as the oldest cultural behaviors as the universal elements of human culture in all communities and groups. Gilan province in Iran, especially their villages, has a unique folklore especially its local games and plays. Nevertheless, it is necessary to document and analyze the immense information about the folklore in these villages before it vanishes in the sea of so...

Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...

In recent years, the problem of inferring and utilizing semantic information has gained considerable interest within the mobile robotics community. In this paper we focus on the problem of how to utilize the local semantic information of objects in a map to solve a navigation task more efficiently. In particular, we consider a wayfinding task and choose a supermarket environment as an example d...

In this paper, an improved Geometric Active Contour model is presented. This model introduced a window function to research the mean information of each pixel’s neighbor region, and constructed a novel signed pressure force function based on the entropy to drive the contour towers the boundary. In order to improve the efficiency and stability of the algorithm, this paper adopts two valued level...

Introduction: Fast and accurate segmentation of thalamic nuclei is important for clinical applications such as treatment of Parkinson's disease or chronic pain syndrome for example. The intrinsic contrast in standard anatomical MR images in the thalamus is very low, therefore direct segmentation of thalamic nuclei is not possible. Since thalamic nuclei have a distinct and well-ordered fiber str...

This paper deals with the autonomous and uniform partitioning of very simple, homogeneous agents onto a fixed number of targets in a geometric space. A set of algorithms will be presented and compared according to the quality of the partitioning and the runtime of simulations with different starting conditions. Random and heuristic approaches will be discussed. The algorithm with the most promi...

We propose a decentralized method for traffic monitoring, fully distributed over the vehicles. An algorithm is provided, specifying which information should be tracked to reconstruct an instantaneous map of traffic flow. We test the accuracy of our method in a simple cellular automata traffic simulation model, for which the traffic condition can be controlled and analyzed theoretically. We show...
