The following paper is a try out on the application of multivariate analysis (regression tree, principal component analysis, and cluster analysis) for classifying hot water chemistry. The number of sample analysed was 416 from all over Indonesia. Regression tree technique has failed to read the data structure due to multi-collinearity effect therefore PCA and cluster analysis were applied. We used open source R statistical packages to do the calculation. Such technique classifies hot water samples into three major clusters: cluster 1 (pure hot water), cluster 2 (mixing water), and cluster 3 (cold-meteoric water). Similar clustering were also detected in the PCA plot. The statistical is able to detect the close and open geothermal system based on data structure. This robust method should be applied to more geothermal system with larger dataset to see its performance.

Originally developed for typesetting a high-energy physics PhD thesis, hepthesis is a LaTeX class for typesetting large academic reports,
in particular PhD theses.
For thesis writing, hepthesis offers a number of benefits:
Attractive semantic environments for rubric sections;
Extensive options for draft production, screen viewing & binding-ready output;
Helpful extensions of existing environments, including equation and tabular;
Support for quotations at the start of the thesis (and each chapter).
The example thesis provided with the package has been pre-loaded into Overleaf to help you get started - simply click the button above to create your own version for editing online.
Version Note: This template has been updated to that supplied with the 2014-12-03 update to hepthesis on CTAN, with a further modification in December 2016 to switch the depreciated \bf commands to \textbf commands, to maintain compatibility after the Overleaf TeXLive 2016 upgrade.
The usage of software has grown as computers become popular. There have emerged, both in academia and in the market, technological solutions for several areas, among them education. On the other hand, classroom teaching and learning continues to suffer from classical educational problems such as lack of student and teacher motivation and lack of clear educational goals. And although software supports learning across a range of disciplines and ages, children's audiences, especially in mathematics, have been little contemplated with the benefits that technological solutions can bring. Therefore, the use of pedagogical approaches, such as Bloom's Taxonomy and Formative Assessments, together with gamification techniques, such as Octalysis, can be used to develop a technological solution that contemplates this public. The present work aims to propose the development of a software to assist the teaching and learning of mathematics for children in the classroom.
