Numerical simulations have recently increased in scale and have often output high dimensional (three-dimensional and time-evolving) datasets. This makes it difficult for users to quickly grasp physical phenomena involved in such datasets. To overcome this difficulty, we propose a spatio-temporal information mapping technique with a map-design capability (spatio-temporal map) by using an informa...

Using a one-dimensional radiative-convective model, we perform a sensitivity study of the effect of ozone depletion in the stratosphere on the surface temperature. There could be a cooling of the surface temperature by -0.2 K due to chlorofluoromethane-induced ozone depletion at steady state (assuming 1973 release rates). This cooling reduces significantly the greenhouse effect due to the prese...

objective: in this research, a new approach termed as “evolutionary-based brain map” is presented as a diagnostic tool to classify schizophrenic and control subjects by distinguishing their electroencephalogram (eeg) features. methods: particle swarm optimization (pso) is employed to find discriminative frequency bands from different eeg channels. by deploying the energy of those selected frequ...

The Growing Self Organizing Map (GSOM) is a dynamic variant of the Self Organizing Map (SOM). It has been mainly used on low dimensional data sets. In this paper the GSOM is applied on high dimensional data sets and its performance is evaluated. Several modifications to the original GSOM algorithm are presented that enable the GSOM to be applied on high dimensional data .The modified version of...

Valeriana officinalis belongs to the Valerianaceae family, is a well-known herb and medicinal plant. Plant roots are commonly used as medicine by pharmaceutical industry. Observation on morpho-agronomic characteristics of valerian propagated in vitro needed determine their morphological production field. The study aimed observe derived from culture. experiment was conducted at Indonesian Spices...

Green finance is considered to be the financial support for green growth. It acts on environmental protection industry through activities reduce greenhouse gas emissions. a new model that combines and activities. In order explore origin development of this model, namely, finance, study adopts method bibliometrics. Based database based Science Citation Index Expanded Social Sciences databases, h...

the present study was designed to investigate the impact of applying fill-in-the-map and construct-a-map techniques on efl learners’ knowledge of tenses. to this end, sixty efl elementary female students, who were selected based on their performance on a standardized teacher-made proficiency test, were randomly assigned into two equal experimental and control groups. in order to be convinced of...
