Se obtuvieron ecuaciones de regresión que relacionan a la temperatura máxima en la superficie interna del tubo y al tiempo de enfriamiento desde 800 ºC hasta 500 ºC de un punto situado en la zona afectada por el calor (ZAC), parámetros que gobiernan la ocurrencia de perforaciones en la pared del tubo y agrietamiento en frío respectivamente, con el calor de entrada de la soldadura, la temperatura de precalentamiento y el coeficiente de transferencia de calor por convección, variables que definen el comportamiento térmico durante la ejecución del proceso de soldadura. Se probó la existencia de una zona en que se satisfacen simultáneamente las ecuaciones obtenidas, para diferentes combinaciones de las variables relacionadas. Se presentaron nomogramas con un importante valor práctico...

They feel frustrate when they ask to their teachers or parents about real necessity of Mathematics, and the answer received is a group of abstract phrases that drive to more doubts instead clarify the necessity of Mathematics, even if you are thinking in to study Humanities, Laws, or other careers that look very far away from Math’s field.
Mathematics helps to explain the world all around. Math is a powerful tool that let us discover the beautiful edges of the universe. Math is a path to grow as person and as a professional.
This group of articles is to encourage students to study math, through the explanation of real life and simple problems, mainly relate to economy and social issues.
I hope that through these pages you discover the importance of Mathematics, and feel more motivated about this wonderful science.

We have observed the difficulties that students face when try to process different data sets, in order to calculate the different measures of central tendency, variation, position, and the interpretation of these results. The text books that are used in our colleges are excellent but the students get lost due to the amount of information that it is presented, and for that reason we have condensed this information, offering very accurate procedures (steps by steps), to find the different parameters.
I hope this brief manual be useful in your goal of learn the basic principles of the Statistic.

The main goal is to offer to students and general population an unbiased view about the activity and recognition of universities all around the world, on the base of measurable indicators like: the web presence and its impact, students-teacher rate, the presence of international students and teachers, and others. To figure in those rankings is one of the biggest challenges for most of the small and medium universities (Carnegie Classification), because those do not have the resources and infrastructure needed to have a great impact and visibility. Nevertheless, small and medium universities cannot renounce to the prestige and visibility that the rankings offer. The alternative to counteract the resources' deficit is to engage and motivate human resources, especially the faculty, with their teaching and research activity, such that they maximize their potentiality. The human resources play a decisive role, as is going to be shown through the following analysis, on the indicators used for some of the most prestigious rankings.
