What Projective Angle Makes the Arc-Length of the Trajectory in a Resistive Media Maximum? A Reverse Engineering Approach
《American Journal of Computational Mathematics》2021年第2期71-82,共12页Haiduke Sarafian 
We consider the motion of a massive point-like projectile thrown with initial velocity with respect to horizontal in a two-dimensional vertical plane under the influence of gravity in a viscose media. Two different ve...

Negative Resistance and Its Impact on a RC-DC Driven Electric Circuit被引量:1
《Journal of Electromagnetic Analysis and Applications》2021年第7期103-110,共8页Haiduke Sarafian 
It is a common misconception that electric “resistance” always is a positive defined electric element. >i.e.>, the plot of the voltage across the resistor, V vs. its current, i is a slanted straight line with...

Alternate Cooling Model vs Newton’s Cooling
《American Journal of Computational Mathematics》2021年第1期64-69,共6页Haiduke Sarafian 
It is customary to apply Newton’s cooling as the standard model investigating the temperature profile of a hot substance exposed to a cool ambient. The rate of change of temperature in Newton’s model is simplistical...

Nonlinear Oscillations of a Pair of Charged Rings
《American Journal of Computational Mathematics》2020年第4期571-577,共7页Haiduke Sarafian 
Two electrically charged rings of different sizes are assembled along their common vertical symmetry axis through their centers. The bottom ring is secured on a horizontal support while the top one is loose. For a set...

Global Characteristics of the Envelope of Family of Trajectories in Resistive Media
《American Journal of Computational Mathematics》2020年第3期431-440,共10页Haiduke Sarafian 
In our recent article [1], we discussed the universal geometric characteristics of the envelope of family of trajectories of projectiles projected with the same speeds and different velocities in a vertical plane unde...
