Clustering by fast search and find of density peaks (DPC) (Since, 2014) has been proven to be a promising clustering approach that efficiently discovers the centers clusters finding peaks. The accuracy DPC depends on cutoff distance (dc), cluster number (k) selection clusters. Moreover, final allocation strategy is sensitive poor fault tolerance. shortcomings above make algorithm parameters onl...

following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. however, this concept has originally been developed for american and european neighborhoods’ planning, it could also be customized for other neighborhoods’. additionally, in the neighborhood scale, the quality parameter f...

BACKGROUND The accessibility to health centers is a limitation to the use of preventive and curative health centers. AIM To assess geographic accessibility using a parameter that integrates information about the use of preventive services and travelling time from home to the health center. MATERIAL AND METHODS We analyzed target geographical areas of 10 community centers located at the Nort...

BACKGROUND Neighborhood environment factors may influence physical activity (PA). The purpose of this study was to develop and test a brief instrument to systematically document and describe the type, features, amenities, quality and incivilities of a variety of PA resources. METHOD The one-page Physical Activity Resource Assessment (PARA) instrument was developed to assess all publicly avail...

The central focus of this article is the interaction between religious actors and urban regeneration in former industrial area Amsterdam North. While there extensive literature on structural, sociocultural, economic impact related processes gentrification, role groups these neighborhood change has largely been ignored. Based ethnographic research, I examine how different Christian movements int...

Dengue disease is a virus-borne illness spread by the bite of female Aedes aegypti mosquito. Jakarta Province has vulnerability to dengue due high population density and percentage urban slum households. This study applied spatial autoregressive (SAR) model identify risk factors that affect number cases in Province. The dependency was accounted for using queen contiguity weight matrix. flood-pr...

The tracking strategy for mobile users in wireless communication networks proposed by Bar-Noy and Kessler in [1] essentially finds a minimal set of reporting centers in the cellular network. The size of the set of reporting centers in the mobility graph, and the vicinity (i.e., the number of non reporting centers in the neighborhood of a reporting center) are measures of the cost of the two mai...

Surface registration is widely used in image-guided neurosurgery to achieve spatial registration between the patient space and the image space. Coarse registration, followed by fine registration, is an important premise to ensure the robustness and efficiency of surface registration. In this paper, a coarse registration algorithm based on the principal axes is proposed to achieve this goal. The...

This paper proposes a cost-benefit framework to address the role of parcel and neighborhood conditions, as well as government policies, and investigates the spatial determinants of urban land expansion in Nanjing, one of the sub-centers of the Yangtze River Delta (YRD). Using spatial regression models, we find the significance of the economy of scale, agglomeration, accessibility, and governmen...

This paper, presents a new image segmentation method based on Wavelets, Particle Swarm Optimization (PSO) and outlier rejection caused by the membership function of the kernel fuzzy local information c-means (KFLICM) algorithm combined with level set is proposed. The segmentation of Magnetic Resonance (MR) images plays an important role in the computer-aided diagnosis and clinical research, but...
