38th parallel north

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…

Introduction For the past 25 years, digital technologies have been swiftly changing the world in business, communications, and politics. Technology has been changing the way humans think, interact, and behave and these days more and more children are growing up accustomed to technology. Long exposure to technology can interfere with the dynamic of face to face relationships. Most people are now accustomed to communicating online, where they can say whatever they want, with little consequence and…

The term Bollywood, were ambiguous, seems to serve different purposes for different people across the world. In academia, the meaning of Bollywood is that, one tends to use the term as loosely as to refer to the Indian film industry as a whole, but much like other Hollywood and Bollywood has also come to stand for auxiliary aspects of film production which includes such as choreography, music, songs, costumes, makeup and even hairstyles. In the past it was known as Hindi cinema, Bombay cinema,…

occurred to Lobachevsky. Instead of trying to prove the fifth postulate he imagined a system where the fifth postulate was different. Instead of specifying only one line being parallel to the original passing through some point, Lobachevsky imagined a space where infinitely many lines could pass through such a point and be parallel to the first line. Today we call this hyperbolic geometry and can imagine it as a saddle shaped space. [4] This convex space has some fascinating properties, such as…

PARALLEL COMPUTING IN SEISMIC DATA PROCESSING 1. INTRODUCTION: Seismic Data Processing involves a critical part in the investigation of oil and characteristic gasses. In the course of the most recent two decades the computational prerequisites of the SDP exercises have grown up numerous folds because of the expansion in the information volume and also the advancement in the scientific calculations. Three dimensional information securing has gotten to be normal as it has ended up important to…

Have you ever been watching a movie, or playing a game, that had you so immersed, you needed to remind yourself this was a fantasy? Storming the beaches of Normandy, traversing the galaxy on an Imperial Star Destroyed, or slinging through downtown Manhattan next to Spider-Man, all different mediums of film, television and video games have the power to integrate their audiences into their world, and create an exciting and enjoyable experience. When fanfiction develops, techniques are employed…

Usability Report on Cogstate’s Brief Battery Louis Gurrieri Royal Melbourne Institute of Technology Executive Summary The Cogstate Brief Battery is a cognitive battery that is designed to assess aspects of working memory and processing speed. It is a computerised test comprised of tasks such as the Detection Task (DET), One Card Learning Task (OCL). All the tasks involve the use of playing cards as the stimuli for the tests, and by using cards it is easy to understand for…

Blown to Bits Chapter 4 was all about the organization of bits, and how the internet is organized. After all, there is simply so much data on the internet, one must wonder exactly how search engines such as Google can pull up websites from this virtual sea of chaos. Well, at first, the internet was mainly a repository for information. Websites were browsed in a hierarchical order, with the websites of most precedence appearing before those with less prominence, which makes a lot of sense if you…
