common spatial pattern (csp) is a method commonly used to enhance the effects of event‑related desynchronization and event‑related synchronization present in multichannel electroencephalogram‑based brain‑computer interface (bci) systems. in the present study, a novel csp sub‑band feature selection has been proposed based on the discriminative information of the features. besides, a distinction ...

This article investigates the role of spatial pattern in residential outdoor water use and implications for the efficacy of non-price restrictions. Drawing on a spatially explicit dataset, the analysis characterizes latent neighborhood effects in households’ outdoor water use and how these effects vary during water restrictions. Results illustrate that spatial patterns in water use vary across ...

Weeds are one of the most important factors in reducing yield in legumes crops. Therefore, awareness of the interaction between weeds and crops as well as identification of their spatial variation pattern in the field is important. To investigate the the effect of  weeds on seed yield of lentil, and also to study the spatial distribution pattern of weeds under rainfed conditions, a field experi...

Background: A society will be sustainable when the basic needs of all its citizens are met. On the other hand, the increasing population of urban areas has increased the demand for public services, especially health services. Today, the level and extent of residents' access to services are calculated on the basis of spatial justice. This study aimed to analyze the extent of realization of spati...

extended abstract 1. introduction earthquake is one of the most important factors in vulnerability of rural areas in iran, which particularly due to shallow epicenter, causes a lot of damage. in addition to the absolute and relative position of different parts of the country, rupture of spatial organization and the lack of hierarchy based on interactive relationship among settlements, are ackno...

Identification of cancer clusters may have an important value to the study of disease etiology in cancer surveillance. We aimed to determine the spatial pattern of childhood cancer cases (CCCs) from 2007 to 2009 in Tehran, Iran. Records of 176 childhood cancer counts (children younger than 15 years old) for 2007-2009 were obtained from Iran’s Ministry of Health and Medical Education. Thereafter...
