About Abraham

For the last 3 years, I have taught After School program as a volunteer for K-7 in Photo Journalism and Electronics Arts in an elementary and middle school. In many presentations, I designed and built 2D/3D graphics and animation programs to stress deeper understanding on some projects. Students in upper grades get to build projects ranging from compound microscope to solar dish framing to digital thermometers all using recycled materials from spent disposable cameras to old cell phones. These projects stressed heavy emphasis in science and mathematics.

I spent more time coaching students who have difficulties in optical physics and algebra all required for some projects. These difficulties were resolved by breaking down equations, relating these equations to real-time hands-on projects. A natural algorithm or a step by step process were implemented where natural logic was easily understood. Formulas were simplified by relating part of a project where it applied to its brief history. Some exercises were implemented to show mastery of each subtopics. These enabled one or more students to easily relate formulas and equations to its applications and elevate skill level and proficiency. At the end of each school year, students were far more advanced than they first started of the program.

I have over 20 years extensive experience in the applications of several multiple subjects, based on degree of difficulty (DOF) such as; General Math, Pre-Algebra, Trigonometry, Geometry, Algebra 1, Algebra 2, Statistics and Probability, Pre-Calculus, Calculus I, II, & III (Multivariable Calculus), Finite Math, Difference and Differential Equations, Laplace Transform/Fourier Transform (Time/Frequency Domain), General Chemistry, Physics (Acoustics, Electronics, Electrodynamics, Electromagnetics, Optics & Light, Plasma/Fusion, and Quantum Mechanics).

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.


ADD/ADHD Request Certification:

My experience from some high school and college communities enable me to deal appropriately and to respond to the special needs of these children and adults.

I have over seven years of experience with young pupils and students both in voluntary teaching and private tutoring capacity. I have specifically provided tutoring services to some high school students with extreme cases of focus and attention deficits with severe sensitivity to distractions. Often, these distractions comes in the form of personal communication devices, laptops, and listening electronics.

The most these students have in common were extreme poor performance in highly abstract mathematics such as some parts in Calculus, Differential Equations, Statistics and Probability. I have addressed these learning differences through a combination of patience, more breaks during intervals, identifying most productive time for the student to learn or being flexible in time, being resourceful in student's inclination to use highly distractive devices and substitute these with productive programs related to the course. By adhering to structured expectations, most students find it convenient for them to work and learn with me.

Autism Spectrum Disorder (ASD)

One of my specialties is in electrical stimulus with over twenty years applied experience in electrical circuit simulation, test, and validation. Human brain neurologic circuit had been the model in the development of computer processing unit. Adults and student behavior when it comes to academic difficulties are the results of brain neuron circuit function.

My experience with young students and adults who had been diagnosed or exhibited symptoms with autism spanned over 7 years. For the last five years, I helped students and adults with devastating and life-changing autistic brain disorders through a series of cognitive and multi-faceted approaches and techniques.

A series of continuing assessment follows before and after every improvement is detected and measured. Each individual case is taken care of differently depending on lightness or severity, and frequency of symptoms. The needs of these individuals with autism varies, hence, techniques and approaches are different. There are similarities to each sensory and processing exercises. The re-training of the brain functions are different for each autistic individual and in most cases, a long term remedy is required.

Differential Equations

Part of the course in undergraduate mechanical engineering was completion of differential equations. First order and second order differential equations were rigorous. My graduate degree in Electrical Engineering required a strong differential equations background prior to taking Systems Equations. Systems Equations encompass rigorous applications of Laplace Transforms, Fourier Transforms, and Z-Tranforms where its applications are found mostly in Test and Measurement, Communications (filter designs), and many others. I have used these applications extensively in systems simulations and designs during my work as a senior engineer.

Electrical Engineering

My Masters in Electrical Engineering degree focused with emphasis in the following courses:

Circuit Design and Analysis, Device Physics, Thin-Film Technology 1, 2, and 3, Fundamental Systems, Network Design, Laplace Transform, Fourier Transform, VLSI (Very-Large Scale Integrated Circuit) Design, Systems Engineering, Advanced Computer Architecture Design 1, 2, and 3.

In addition, I am proficient in both numerical analysis and simulation that include characterization in Signal Integrity, EMI/EMIC (Electromagnetic Interference), RF/Microwave, Thermal and Reliability.

Linear Algebra

Experience in linear algebra begins at the high school level to the graduate studies in electrical engineering. These topics included linear equations, determinants, matrices, orthogonal matrices, linear transformations, vectors, eigenvalues and eigenvectors, complex vector spaces, real inner product spaces, vector spaces with matrices, linear differential calculus.

In addition to the above academic experience at a high school and college level mathematics, advanced applied topics in graduate electrical engineering included my experience in the applications of linear systems to circuit analysis, linear and non-linear circuit analysis, Laplace transformation, Fourier transformation, fundamental systems, impulsive functions, analog-computer simulations, controllability and observability, Popov-Belevitch-Hautus tests, linear state-variable feedback, quadratic regulator theory for CT systems, compensator design, multivariable systems, general differential systems and polynomial matrix, and time-variant systems.

Mechanical Engineering

I hold a Mechanical Engineering degree. I also have 15 years combined experience in mechanical engineering from testing, research, and analysis to equipment operation in turbocharged diesels, turbo-generators, turbomachinery, voltage regulators, and many other rotating equipment.

Mechanical engineering courses I've completed and have had experience in industry and in teaching include:

Mechanics of Materials (Statics), Strength of Materials (Dynamics), Kinematics of Machine Elements, Machine Design, Internal Combustion Engine (ICE) Design, Thermodynamics 1 and 2, Hydraulic Machinery, Climate Control Design (Heating, Ventilation, Air Conditioning, Refrigeration), Noise and Vibration Test and Analysis, Power Plant Design, Power Plant Process Design and Construction, Rapid-Part Manufacturing (RPM)

In addition, I am proficient in numerical analysis on Fluid Flow Dynamics, Shock and Vibration, Noise, Cavities and Creeps, Solder and Solder Mask, Fatigue and Cracking, Surface Flow, Reliability.

Video Production

Unique experience in video production in that I combined several interactive motion and graphics input and output files into streaming video presentation. These files included 3D animation, 3D graphics, music dubbing while teaching at both elementary and middle school as part of the school's Photo Journalism and Electronic Arts course that I started as an after school program for the school for the last 3 years. This course provided students to learn both technical and symbolic representation of video captures, video editing, and video post-production used in Photo Journalism and Electronic Arts.

The video production mainly focuses on the educational applications platform where students learn the basics of using video equipment, processing tapes, data transfer, video edits, and programming integration to computers. Post video production provided students to compare technical requirements with that of the limitations of video equipment. It also enables students to refine post video files into professional photos based from captured videos extracted from frames per second films using photo editor.

Web Design

Designed and installed an interactive website under contractual agreement for an electrical contractor using both an HTML editor and writing HTML, PhP, javascript and Mysql that provided online visibility, online service business, and communications utility. The functional communications of the program uses a communications hardware with modified written javascript and PhP codes enabling dispatch from submitted client forms to simultaneously call-in prospective contractors through text messaging and mobile celluar/landline platforms by zip code location. This systems provided instantaneous response from the contractors to the calling client. The program also streamlined payment methodology by direct deposit or credit/debit card.

While at an elementary and middle school, I started the Photo Journalism and Electronics Arts after school program providing opportunities to these elementary and middle school students partly the ability to design and develop basic website design using HTML Editor and HTML codes writing.
