This paper presents a simple and easy implementable Least Mean Square (LMS) type approach for frequency estimation of three phase power system in an unbalanced condition. The proposed LMS type algorithm is based on a second order recursion for the complex voltage derived from Clarke's transformation which is proved in the paper. The proposed algorithm is real adaptive filter with real parameter...

The paper presents a traffic simulator intended to be used in Bucharest, Romania, in order to solve usual traffic problems and obtain better traffic management performances with the same basic route network. The simulator makes short time traffic predictions starting from data extracted from real traffic. Usually, traffic predictors use statistic methods instead of simulation techniques. The ad...

This study aimed to develop real-life performance-based tasks in Business Mathematics (RLPBTs) following the ADDIE’s model of instructional development. Using descriptive-developmental research design, developed RLPBTS with mathematics experts, department head, bank manager, teachers, and students as respondents. The RLPBTs consist plans. Each plan has these components: Introduction, Learning C...

There are several systems in real situations that only accept a single and acceptable benchmark for efficiency improvement. For instance, when we are going to select a target for a country, the target country should be as close as the view of culture, economics and politics to the inefficient country. Otherwise, it would not be acceptable. Therefore, an inefficient country for several reaso...

Evidence suggests that in Iwaija, a non-Pama-Nyungan language of northern Australia, the Intonation Phrase (IP) is an integrated entity, one which is typical of a cursus language (Pulgram,1970) like French, in which words in connected speech give up some of the properties they exhibit in isolation. A salient feature of the prosody of this language is syllabification across content word boundari...

Nowadays (triangle) meshes are by far the most commonly used representation for modeling geometric objects in computer graphics. However, in many situations meshes are not well suited. For instance the creation of convincing models for fluids, smoke, fire, organic structures, repetitive structures, etc., is very tedious and sometimes impossible using meshes. There are several reasons why meshes...
