sustainable transportation with the aim of urban sustainable development aims to improve the environmental quality and the socio-economic condition. one of the most important strategies for achieving sustainable transportation is planning and designing for walking, or in other words increasing urban walkability. therefore, increased walkability has become a key issue in urban planning. understa...

Differential evolution (DE) algorithms compose an efficient type of evolutionary algorithm (EA) for the global optimization domain. But DE is not completely free from the problems of slow and/or premature convergence. In this paper, an improving clustering-based differential evolution with chaotic sequences and new mutation operator (CCDE) is proposed for the unconstrained global optimization p...

The continuous p-median problem (CPMP) is one of the most popular and widely used models in location theory that minimizes sum distances from known demand points to sought called centers or medians. This NP-hard also useful for clustering (automatic grouping). In this case, are considered as cluster centers. Unlike similar k-means model, less sensitive noisy data appearance outliers (separately...

Reflecting on the current reorganization of the relationship between the state and civil society, the health care field is involved in an intense debate over the organization and use of government and private health services. The authors propose an alternative, consisting of the implementation of primary health care clinics, managed by local institutions and funded by the Unified Health System....

INTRODUCTION Both socioeconomic status and travel time to cancer treatment have been associated with treatment choice and patient outcomes. An improved understanding of the relationship between these two dimensions of access may enable cancer control experts to better target patients with poor access, particularly in isolated suburban and rural communities. METHODS Using geographical informat...
