In the past years I had the opportunity to participate in the Texas A&M E3 (Enrichment Experiences in Engineering) Program, in the University of Houston RET (Research Experiences for Teachers) Program. and in the PATHS-UP RET (Precise Advanced Technologies and Health Systems for Under-served Populations) at Rice University. Under the supervision of distinguished researchers, I worked short projects immersed in leading-edge research in engineering.
Summer 2013. Working with Dr, Devesh Ranjan, I developed, using MS-Excel VBA, a simulator for heat diffusion in one-dimensional homogeneous and isotropic media.
Summer 2014. Under the supervision of Dr. Cunjiang Yu, I performed the statistical analysis of the change in dimensions produced by the fabrication process on nano-circuits.
Summer 2015, Under the supervision of Dr. Mina Dawood, I made an statistical analysis of the mean lives of cracked steel structures repaired with different configurations of patches of carbon fiber.
Summer 2018. Working with Dr. Ashutosh Sabharwal, I developed a graphical interface (GUI) to fit harmonics for the Photoplethysmographic signal obtained from a pulse oximeter, The GUI was developed in Python and MS-Excel
Assign-4 Poster.pdfCopy of RET-MiguelRamirez-Poster-Final.pdfCopy of RET2015-MiguelRamirez-Poster.pdfMRamirez-RET_Rice_Poster-Final.pdfFrom each one of the above projects, a lesson and an activity were created, giving to GPHS students the opportunity to be engaged in classwork related with state-of-the-art research in engineering. These lessons and activities were submitted to the k-12 web based digital curriculum library TeachEngineering, were engineers and experienced teachers reviewers evaluated and made suggestions and corrections to these lessons-activities, aligned to high educational standards. Once a lesson or activity met the required standards is accepted to be published in the TeachEngineering website. At present GPHS is a curricular contributor for this recognized and awarded digital collection.
For my past years AP Statistics classes, the next lessons-activities were developed and accepted as part of the TeachEngineering digital library (click on image to open link):
Because of the great impact these high standards lessons-activities have had on my students , and the great feedback and learning obtained by myself during the writing and revision processes, I want to give to my students more high quality lessons where they find an engineering application of the concepts learned in class. For my AP Calculus classes I have created the next lessons-activities (click on image to open link):

A Note about the Constant Slant of Optimized Right Pyramids.pdfIn this paper, posted in www.academia.edu on May-27-2020, I presented an original idea to find the value of the fundamental trigonometric limit that is the key in all introductory Calculus courses to solve many other trigonometric limits and obtain other important results. No textbook or lesson I have found with this approach, or any other kind of explanation or practical example, other than the derivative of the function sine using the limit definition, where this fundamental limit can be found or be necessary, it just "magically appears" as a Theorem at the beginning of the trigonometric limits section, and used.

The Calculus Fundamental Trigonometric Limit and the Circle.pdfIn a Calculus course, students learn that squares are optimized rectangles, this is, squares are the rectangles having the maximum area and minimum perimeter. In this paper I present patterns found when optimizing subdivided rectangles. During the past ten years I have been teaching my students to solve this kind of problems, but I have to say that I never was aware of these patterns until a non-Calculus student used them to quickly solve one of these problems. I decided then explore this special patterns and write my findings.

Volumes_Of_Complex_Solids.pdfMy Hobby, collecting slide rules, gives me great learning moments. The use of these mechanical calculators not only makes you use your numerical sense and mental math, but also makes you play with your Arithmetic Concepts and your Algebraic skills, making you to re-write the expressions you want to evaluate in more efficient ways. I wrote the next paper to introduce my students in the use of a simple slide rules to evaluate complex algebraic expressions. Remember that a slide rule is the materialization of the rules of logarithms, and that these were invented to simplify annoying operations involving multiplications and divisions, or powers and roots.
