Emotion perception is critical for behavior prediction. There are many ways to capture emotional states by observing the body and copying actions. Physiological markers such as electroencephalography (EEG) have gained popularity, facial emotions may not always adequately convey true emotion. This study has two main aims. The first measure four emotion categories using deep learning architecture...

Recent methodologies for audio classification frequently involve cepstral and spectral features, applied to single channel recordings of acoustic scenes events. Further, the concept transfer learning has been widely used over years, proven provide an efficient alternative training neural networks from scratch. The lower time resource requirements when using pre-trained models allows more versat...

To monitor electrical indications from the heart and assess its performance, electrocardiogram (ECG) is most common routine diagnostic instrument employed. Cardiac arrhythmias are only one example of many conditions people might have. ECG records used to diagnose an arrhythmia, abnormal cardiac beat that can cause a stroke in extreme circumstances. However, due extensive data contains, it quite...

Presented paper deals with comparison of various methods for time-frequency representation of a signal with time-varying behavior. We choose methods such as wavelet analysis, multiple window method using Slepian sequences, time-frequency varying autoregressive process estimation and time-frequency Fourier transform representation (periodogram). We apply these methods first on the simple simulat...

reservoir models are initially generated from estimates of specific rock properties and maps of reservoir heterogeneity. many types of information are used in reservoir model construction. one of the most important sources of information comes from wells, including well logs and core samples. unfortunately well log and core data are local measurements that may not reflect the reservoir behavior...

A methodology for representing the patterns of dependency in a dependency grid using partial order scalogram analysis by coordinates (POSAC) is presented. The technique, devised by Shye (1985), shows these patterns as hierarchical relationships which indicate superordinate and subordinate resources. An index of depth of resource support is calculated in addition to an index of breadth of resour...
