Motor Speed Control

Introduction and Objectives In this lab you will control the speed of a motor. Figure 1 shows the hardware setup, which is the same as for Week 1 of Lab 4. You will use the potentiometer on your evaluation board to set the desired speed of the motor, and you will control the speed through the PWM output of the HCS12. You will measure the speed of the motor using an input capture pin, and display the desired and actual…

Importance of Mathematics and Statistics to Economics

INTRODUCTION Statistics and mathematics are everything to economics. infact statistics and Mathematics, the economic field wouldn’t even exist. Economist need statistics to represent data, to track and store information, to identify trends, to attribute value and mathematics to calculate those figures.The way to look at the relationship between statistics and economics is that economics is essentially the study of human decisions and trends, and how these have a financial impact. Economists rely on information to form analyses, understanding and opinion…

Alternative Communication System

Pascal was an outstanding genius who studied geometry as a child. At the age of sixteen he stated and proved Pascal’s Theorem, a fact relating any six points on any conic section. The Theorem is sometimes called the “Cat’s Cradle” or the “Mystic Hexagram.” Pascal followed up this result by showing that each of Apollonius’ famous theorems about conic sections was a corollary of the Mystic Hexagram; along with Gérard Desargues (1591-1661), he was a key pioneer of projective geometry….

Beautiful Mind

John Nash first arrives as a new graduate student at Princeton University. There he meets his roommate Charles, a literature student, who soon becomes his best friend. He also meets a group of other promising math and science graduate students. John sometimes goes out to a bar with his fellow students to try to meet women, but is always unsuccessful. However, the experience is what ultimately inspires his work in the concept of governing dynamics, a theory in mathematical economics….

Tip Top Markets

As we can see on the table above, the number of out-of-stock complaints is the highest with 61 complaints, while the lowest complaints with 5 is the fish not being fresh. The category Others includes all other complaints that minor complaints like ATM ate card, lost wallet, dislike store decoration, etc. Using the cause-and-effect diagram we will determine the main causes of the out-of-stock problem because it is the category which has most number of complaints. Based on the cause-and-effect diagram,…

Mathematics, the Connection Between Art and Science

Although there are many differences that set art and science apart, they share one undeniable commonality. This bond that is present between what is otherwise considered as polar opposites is mathematics. As shown in Professor Vesna’s lecture, mathematics is imperative to the development of art. Through math, artists have come to understand perspective, proportion, and geometrics. In terms of science, mathematics is the foundation which every theory stands upon. Nature, humans, and the digital world would have been impossible to…

National Achievement Test

This study tried to analyze the Mathematics achievement of the second year high school students of Hermano Miguel Integrated School as revealed in the National Achievement Test (NAT). The relationship between the achievement in Mathematics and their profile was also determined. The results were utilized in developing and evaluating the proposed expanded remediation module. What is the profile of the students as regards age and gender? Gender. In terms of age, it can be seen from table 1 that out…

Tire Testing

The circumference of the tire that fits on a 16 inch wheel is greater than the circumference of a tire on a 15 inch wheel. Discounting sidewall depth, which would be the same on both tires since they differ only by diameter, the circumference (2 * Pi * radius) of the 15 inch tire is 47.12″ and the circumference of the 16 inch tire is 50.27″.  2000 miles equals 10,560,000 feet, which equals 126,720,000 inches.  Therefore the 15 inch tire…

Why you Selected Your Major

“Millions of people saw an apple fall, but Newton was the one who asked why”, said Bernard Mannes Baruch (1870 – 1965) an advisor to more than 40 Presidents. And that is why I chose the major Engineering, because I just want to know why. Why do planes fly? Why does the Sun shine? I believe that Engineering is the answer to all of the scientific questions asked. The definition of Engineer is a person that is an expert in…

Current Event Research Paper

The research paper I found to discuss was a study done on motivation in the work place in a hotel in Konya, Turkey. Since I am currently in the hotel industry I find it very interesting that these individuals were able to conduct a mathematical analysis of what drives employees to stay committed in the work place. The three factors they tested to see which had the highest effect on employees were intrinsic motivation, extrinsic motivation, and work motivation. In…

History of Circle

The word “circle” derives from the Greek, kirkos “a circle,” from the base ker- which means to turn or bend. The origins of the words “circus” and “circuit” are closely related. The circle has been known since before the beginning of recorded history. Natural circles would have been observed, such as the Moon, Sun, and a short plant stalk blowing in the wind on sand, which forms a circle shape in the sand. The circle is the basis for the…

Golden Ratio

The Golden Ratio which is also referred to as golden mean, golden section or divine proportion is a number frequently encountered when calculating ratios of distances particularly in simple geometric figures like pentagram, dodecahedron, pentagon and pentagram. It is an irrational constant in mathematics which is given an approximate value of 1. 6180339887 and is symbolized by the Greek letter phi or in other words , or sometimes . Most of the greatest mathematicians in the ancient Greece, Euclid and…

Are the Social Sciences Really Inferior_

Prologue It is a common notion that the social sciences, as it were, are inferior to the natural sciences when it comes to being a “science”. Some sects in the society even questions the credibility of the claim of the social sciences that they are indeed a science; several faction of the society views social science as a whole as being inferior to the natural science, a number of them even does not consider social sciences as a science at…
