We present a novel technique to identify calendar-based (annual, monthly and daily) periodicities of an interval-based temporal pattern. An interval-based temporal pattern is a pattern that occurs across a time-interval, then disappears for some time, again recurs across another time-interval and so on and so forth. Given the sequence of time-intervals in which an interval-based temporal patter...

The Javanese calendar has been in use since July 8, 1633 AD, during the time of Sultan Agung. In calendar, there is a cycle called kurup. Aboge one kurup third after Awahgi and Amiswon. Currently, reached fourth circle, namely Asapon. Even though it kurup, special because seen as religious sect. Regarding determining beginning fasting other holidays, its own method based on Javanese-Aboge Calen...

With the deployment of multi-modality and large-scale sensor networks for monitoring air quality, we are now able to collect large and multi-dimensional spatio-temporal datasets. For these sensed data, we present a comprehensive visual analysis approach for air quality analysis. This approach integrates several visual methods, such as map-based views, calendar views, and trends views, to assist...

We propose a suite of tests based on two-state Markov chains for experimentally assessing the dynamic performance of a variety of simulation event calendar implementations. In contrast to previous studies based on the standard hold model for evaluation of performance statically, the proposed Markov hold model is more general and can be used to examine how different implementations respond dynam...

consideration of the current-voltage (i-v) characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (mppt). having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. in this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathema...

Predicting future behavior of chaotic time series system is a challenging area in the literature of nonlinear systems. The prediction's accuracy of chaotic time series is extremely dependent on the model and the learning algorithm. On the other hand the cyclic solar activity as one of the natural chaotic systems has significant effects on earth, climate, satellites and space missions. Several m...

Educational organizations have different methods of deploying E-learning systems, of which is using and developing open-source e-learning systems. One should consider some criteria when choosing a suitable system includes: documentation, usage rate, structure, standards support and educational strategy. In this work an e-learning software system has been elected and five phases of modification ...
