Appropriate choice of number of electrodes and their positions are essential in Brain-Computer Interface applications since using less electrodes collects insufficient information for classification purposes whereas using more collects redundant information that could degrade BCI performance. This paper proposes a novel method of optimizing EEG channel selection by using the regularized Common ...

Changes in the wind speed of Iraqi-Kurdistan region are associated with many types teleconnection patterns. Daily datasets for eight meteorological stations were gathered from Sulaymaniya, Penjwen, Hallabja, Kalar, Erbil, Sallahadin, Zakho, and Duhok weather stations. spectral comparability between daily sites prominent atmospheric indices was implemented North Atlantic Oscillation (NAO), South...

In this paper we investigate the discovery of association rules from a particular kind of images, namely document images. Document images are initially processed to extract both their layout structures and their logical structures. To take into account the inherently spatial nature of the layout structure, a spatial data mining algorithm is applied, which returns spatial association rules. We i...

the analysis of the relationship between spatial distribution of environmental factors andvegetation types is crucial for understanding mountainous ecosystems. in this research agis based approach was used to produce a vegetation map for sabzkouh protected area inthe chaharmahal-va-bakhtiari province. to identify environmental parameters affecting thevegetation cover, 6 primary and secondary en...

The Common Spatial Pattern (CSP) algorithm is an effective and popular method for classifying 2-class motor imagery electroencephalogram (EEG) data, but its effectiveness depends on the subject-specific frequency band. This paper presents the Filter Bank Common Spatial Pattern (FBCSP) algorithm to optimize the subject-specific frequency band for CSP on Datasets 2a and 2b of the Brain-Computer I...

The relationship between the information capacity and the corresponding beam pattern of a multi-sensor array is investigated. From this, bounds on the information capacity improvements possible utilizing spatial filtering in a mulituser environment are established.

In this paper we present techniques for detecting mines using data acquired at multiple wavelengths (multi-spectral) or at multiple times (multi-temporal). Both types of data employ vector-valued pixels, and therefore they have a common mathematical structure. For the multi-spectral data we show that the performance of standard algorithms can be improved signiÞcantly through spatial whitening w...

Modular femoral heads have been used successfully for many years in total hip arthroplasty. Few complications have been reported for the modular Morse taper connection between the femoral head and trunnion of the stem in metal-on-polyethylene bearings. Although there has always been some concern over the potential for fretting, corrosion, and generation of particulate debris at the modular junc...
