Spatial Filter Bank based on Probabilistic Common Spatial Pattern in Motor Imagery BCI systems
2016 23rd Iranian Conference on Biomedical Engineering and 2016 1st International Iranian Conference on Biomedical Engineering (ICBME), 2016Recently, Motor Imagery (MI) based on Brain Computer Interface (BCI) systems have been noticed for neuro-rehabilitation methods. The challenging key is to correct detection of MI tasks. Probabilistic Common Spatial Pattern (P-CSP) is the most recent and efficient method for discriminating two classes of electroencephalogram (EEG) from Motor Imagery (MI)

Spatial and Temporal Patterns in the Seed Bank and Vegetation of a Desert Grassland Community
The Journal of Ecology, 1988SUMMARY (1) Plant and seed temporal and spatial patterns, and the correlation between vegetation and seed bank were examined from 150 samples collected from an 8-ha site in a desert grassland community in north-central New Mexico, U.S.A. (2) Total plant cover increased through the growing season, but relative cover of all species except three annuals ...

Nested spatial patterns in seed bank and vegetation of Mediterranean old‐fields
Journal of Vegetation Science, 1991AbstractA nested sampling design was used to describe the spatial patterns for the species richness and composition in the seed bank and vegetation of three Mediterranean old‐fields (1, 7, and 15 yr after the last ploughing). Three scales were examined hierarchically: sampling units within plots of 0.25 m2 for the vegetation and of 0.05 m2 for the seed

Spatial patterns of the germinable soil seed bank in northern Patagonia
Seed Science Research, 1998AbstractThe spatial variation of the soil seed bank in the steppe ofLarrea divaricataandStipaspp. was evaluated in relation to the spatial pattern of the established vegetation, over two years. Plant distribution was expected to affect the spatial pattern of the soil seed bank.

Spatial Pattern Analysis of Seed Banks: An Improved Method and Optimized Sampling
Ecology, 1988Analysis of spatial pattern of the seed bank of an old field in Maryland showed that the seed bank was composed primarily of annual and short—lived perennial species. Tree and shrub species were poorly represented. Seed abundance decreased with depth in the soil. The seeds of all species generally had clustered distributions in the soil. However, there

Spatial Patterns of Soil Seed-Bank Related to Some Soil Properties
2001Precision agriculture requires new approaches to research that are designed explicitly to improve understanding of the complex interactions among multiple factors affecting crop growth and farm decision making. The variability of weed distribution is related to several pedoclimatic and agronomic factors.

Multiclass voluntary facial expression classification based on Filter Bank Common Spatial Pattern
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008This paper investigates the classification of voluntary facial expressions from electroencephalogram (EEG) and electromyogram (EMG) signals using the Filter Bank Common Spatial Pattern (FBCSP) algorithm. The FBCSP algorithm is an autonomous and effective machine learning approach for classifying two classes of EEG measurements in motor imagery-based ...

Filter-bank local region complex-valued common spatial pattern for Motor imagery classification
2020 8th International Winter Conference on Brain-Computer Interface (BCI), 2020This paper represents a novel motor-imagery (MI) classification method based on a local region filter-bank common spatial pattern (LRFBCSP) using complexed form of electroencephalography (EEG) signals. LRFBCSP approach selects the MI-relevant local region which is constructed by individual channels and their neighbors by comparing their eigenvalue ...
