Optimization of spatial complex networks
(Elsevier, 2017)
First, we estimate the connectivity properties of a predefined (fixed node locations) spatial network which optimizes a connectivity functional that balances construction and transportation costs. In this case we obtain a ...
A survey on frameworks used for robustness analysis on interdependent networks
(Wiley, 2020)
The analysis of network robustness tackles the problem of studying how a complex network behaves under adverse scenarios, such as failures or attacks. In particular, the analysis of interdependent networks' robustness ...
Topology of Plant - Flower-Visitor Networks in a Tropical Mountain Forest: Insights on the Role of Altitudinal and Temporal Variation
(Public Library of Science, 2015)
Understanding the factors determining the spatial and temporal variation of ecological networks is fundamental to the knowledge of their dynamics and functioning. In this study, we evaluate the effect of elevation and time ...
Establishing an acquisition and processing protocol for resting state networks with a 1.5 T scanner: A case series in a middle-income country
(Wolters Kluwer Health, Inc.Estados Unidos, 2020-06)
Objective: The aim of this study was to characterize the capability of detection of the resting state networks (RSNs) with functional
magnetic resonance imaging (fMRI) in healthy subjects using a 1.5T scanner in a ...
Exploiting spatial diversity in overloaded MIMO LDS-OFDM multiple access systems
(IEEE, 2017)
In this paper, we consider the deployment of multiple antennas as a way to exploit spatial diversity in the uplink of multiple access systems that adopt low-density spreading (LDS) with orthogonal frequency-division ...
Urban mobility analysis with mobile network data: a visual analytics approach
(IEEE, 2018-05)
Urban planning and intelligent transportation management are facing key challenges in today's ever more urbanized world. Providing the right tools to city planners is crucial to cope with these challenges. Data collected ...
Modelling the internet as spatially constrained interdependent networks
(CEUR-WS, 2017)
The modern world has made the Internet a need for the people. More than ever before we have Internet dependent systems and devices. Thus, it is important to maintain the infrastructure of the Internet working properly. In ...
Are returns to scale with variable network size adequate for transport industry structure analysis?
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2006-08)
It is customary to analyze transport industry structure using two indices: (1) economies of density and (2) economies of scale with variable network size. The latter has been defined to analyze the behavior of costs when ...
Rock art and social networks among hunter gatherers of north-central Chile
(Academic Press Inc. Elsevier Science, 2016)
This paper discusses the relationships between rock art and the production of social networks among hunter-gatherers from the Late Holocene in central-northern Chile. Despite the low visual integrity of the paintings under ...
Spatial disaggregation of traffic emission inventories in large cities using simplified top-down methods
(2009)
Simple, inexpensive and accurate methods for assessing the spatial distribution of traffic emissions are badly needed for the environmental management in South American cities. In this study, various spatial disaggregation ...
