Introduction
In this lab motion will be represented by graphs that plots distance and velocity vs. time. A motion detector will be used to measure the time it takes for a high frequency sound pulse to travel from the detector to an object and back. By using this method sound can determine the distance to the object, or its position. This device will determine in what direction the woman in the video was walking and how fast she was walking. This information will be plotted on a graph and show the motion as the woman moves, whether she speed up or slowed down. Logger Pro will use the change in position to calculate the object’s velocity and acceleration. All of this information is in graph form. A qualitative analysis of the graphs of motion will help you develop an understanding of the concepts of kinematics.

Theory
The motion of an object can be measured using a motion detector. The detector helps in knowing where an object is according to an indication point. How fast and in what direction an object is moving, and how an object is accelerating is necessary in understanding the kinematics graphs. The Motion detector uses pulses of ultrasound that bounces off of an object to determine the position of the person/object. As the person moves, the change in its position is measured many times each second. The change in position is expressed as velocity (meters /second). The change in velocity from moment to moment is expressed as acceleration (meters /second /second). The position of an object at a particular time is then plotted on a graph.

Methods, Procedures, and algorithms
Upon opening Logger Pro, the file labeled “Graph Match” was then opened from the sample movies folder. Once this file was opened, the video analysis panel was then enabled. The “Set Scale” was located on the panel and pressed and a green line was drawn from...

...connected graph G, a spanning graph of G that is a tree is called a spanning tree. A spanning tree for an undirected graph G = (V,E) is a graph G’ = (V,E’) such that G’ is a tree. In other words, G’ has the same set of vertices, but edges have been removed from E so that the resulting graph is a tree. This amounts to saying that G’ is acyclic. If G is directed, it means that cycles have been removed. Since a tree with |V|...

Introduction
A.Aho and J.Ulman acknowledge that “Fundamentally, computer science is a science of abstraction.” Computer scientists must create abstractions of real-world problems that can be represented and manipulated in a computer. Sometimes the process of abstraction is simple. For example, we use a logic to...

...circuits for impedance matching of wideband transducers
ABSTRACT
Wide band piezo-composite transducer is a next generation transducer for under water application. The impedance matching on the interface between electro-acoustical transducer and electrical transmitter has been the most important subject to confirm the high transmitting efficiency. Because the impedance of a wide band transducer depends on signal frequency, it is difficult to...

...had its roots in the work of two mathematicians, Paul Erdos and Alfred Renyi. Their work suggested that systems such as communications could be effectively modelled by connecting nodes with randomly placed links. Their simple approach revitalised graph theory and led to the emergence of the field of random networks.
An important prediction of random network theory is regardless of the random placement of links most nodes will still have approximately the same number of...

...Double stub impedance matching
Impedance matching can be achieved by inserting two stubs at specified
locations along transmission line as shown below
There are two design parameters for double stub matching:
The length of the first stub line Lstub1
The length of the second stub line Lstub2
In the double stub configuration, the stubs are inserted at predetermined
locations. In this way, if the load impedance is changed, one simply has to...

...Application of Accounting Concepts
Matching Principle & Accrual Concept
Accrued / Prepaid Expense & Accrued or Advance Revenue
To ensure an accurate matching of expenses and revenue under the accrual basis, it is necessary
to include all revenue earned but not received and expenses incurred but not paid. Such
adjustments comprise adjustments for :
Accrued Revenue
Accrued Expenses
On the other hand, many recorded costs and revenues benefit more than one...

...Graphs and Function
What is the relation between the graphs and function and how was it applied in the real world?
Graphs are frequently used in national magazines and newspaper to present information about things such as the world’s busiest airports (O’Hare in China is first, Heathrow in London is sixth), about the advertising-dollar receivers in the United States (newspaper are first, radio is fourth) and about NCAA men’s golf team title...
