models up to 390 millions particles. Although the implementation of DD for the semi-implicit methods is generally a very big challenge, specific problems may have features that can simplify this task: Ovaysi and Piri cite{Ovaysi-2012} developed a parallel versions of Modified Moving Particle Semi-implicit (MMPS) to model fluid flow in porous media. The authors took advantage of the almost homogenous distribution of particles throughout the whole simulation, which enable to use a simplified…
Describe how the quicksort works including a discussion of the pivot, how it is selected, and why the pivot is important to the quicksort. Let’s start describing what pivot is, its function and why is so important. The pivot is the element that basically divides the array in two halves, where the left half contains the smaller values and the right half contains the greater values. The pivot can be selected in many ways. First, last, middle element, actually any element of the array can be…
These have four wires on them (see Figure One-a). They are tricky to control because they require changing the direction of the current flow through the coils in the proper sequence. We will discuss these motors further when we get to the topic of DC motor control. * Unipolar motors, with two center-tapped coils which can be treated as four coils (see Figure One-b). These have six or eight (or sometimes five) wires, and can be controlled from a microprocessor with little more than four…
The parallels of the creation stories of the Hawaiian’s and that of Hinduism is too evident to not compare. While the stories have many variances, the context and effect in their particular region is almost identical. Both stories tell of a time where emptiness and unknowns were the norm, however the stories of Kumulipo and Purushasukta parallel in the creation of the world as we know it through a specific event whether it be the sacrifice of the ultimate being or a night of creation. The…
Multiversal ethics points out how, for every possible event(creating a multiverse), there is a universe where things ended badly. There may be a universe where a close call turned into a car accident, paralyzing someone from the waist down, or someone’s common cold turning into a fatal disease. Every event becomes a coin toss, as an individual reading this paper, you may have died hundreds of times in other universes, but you were the lucky version that won all the coin tosses. This concept is…
Are we alone in the universe? Men have struggled with this idea throughout the whole of human history. M. Night Shyamalan takes a fresh look at this idea in his sci-fi blockbuster film Signs as he follows the journey of a family in crisis as they face an alien invasion. As the story unfolds, Shyamalan reveals his ideas on the universal theme of man’s struggles with faith and a belief in the divine design of the universe through his use of allegory, conflict, and character. The primary way…
How viable is time travel? Time; it organizes our lives and universe into an ordered series of moments. At first thought, time is one of the most fundamental aspects of our lives and the world we know. However, time is in fact incredibly subjective; everyone experiences this indefinable concept differently. Einstein's Theory of Special Relativity is based upon the idea of frames of reference. A frame of reference is where an observer is situated. In order to develop a universal concept of time…
The Multiverse Theory is one of the most talked about theories in the modern age. It entails how there is a chance that we are not the only universe in existence but rather there are tens of thousands of other universes. This leaves all kinds of possibilities to the imagination; maybe someone was born with red hair rather than blonde, maybe someone became president rather than a physics professor. There are an infinite number of possibilities which causes the Multiverse Theory to also be a…
tainted with the vastness of reality. Through an account of the universe 's power and the world of cartoons, Flynn utilizes symbolism to explore human reality. Flynn reveals that in cartoons, characters are in control of their environment. Additionally, children who play in sandboxes produce an alternate universe. These examples reveal how people consciously seek to ignore the truths of reality. Through an analysis of the universe 's power and cartoon physics, Flynn exposes how innocence…
This sort of variation, if there were to be a variation (a term which is very significant to Darwin), in Paley’s opinion, should not account for the non-existence of a God in the Universe. Reaching the conclusion that the successor of the watch is not connected to a creator is illogical, according to Paley. In Paley’s analysis of the watchmaker, he summates that the watch “must have had, for the cause and author of that construction…
