Up until now, the Xbox 360 gaming console has sold over 76 million units since its launch in 2005. This device is entirely dedicated to gaming with no other auxiliary uses. In 2013, Microsoft decided to target a larger market as well as demographic. Statistics show that over 96% of Americans own television sets. However, only 49% own gaming consoles. For this reason, Microsoft decided to unveil a new upgrade of the console that integrates with the living room. The new console got named as the Xbox One. This device can surf the web, play games, stream movies and ...

Discuss why the characteristics of victims are so important to crime analysis

Although victim characteristics is only one of many aspects considered in theoretical victimology, which studies the victim factors in the crime (Fattah, 2000), these characteristics has been found influential in the planning and eventual commission of the crime. Since the history of this field of study, there was a running belief that the victim may have a contribution in the genesis of the crime. As early as 1940, despite many crimes wherein the victim has little or no direct or indirect contribution in the occurrence of the crime, many observers noted that there was real interaction and mutual contribution ...

A Statistical Approach

Reading is one of the first abilities developed and enforced during the first years of education across the world. Duggan (2009) states that one of the two most characteristic attributes a skillful reader has is his speed and ease while reading, the other being the understanding of the text. Conversely, the experience of reading can be enhanced or deteriorated by outside elements other than the reader himself. Irlen’s study (as cited by Morrison, 2011) suggests that visual perception is distorted when reading black words on a white background, ...

I am really interested in art and aspire to be an artist myself. Therefore, I wanted to benefit from this assignment by the means of exploring the flirtations of art with mathematics. Among all great artists, M.C. Escher is the one who comes to mind when one thinks of mathematics. As I researched deeper into his art, I found out that he is more than just flirting with mathematics but in a marital relationship. So much that he can be referred to as a secret mathematician. Escher’s fascinating work holds inside a great knowledge of Euclidean and Non-Euclidean ...

INTRODUCTION TO GEOGRAPHY INFORMATION SYSTEMS (GIS)

Q1. Main data sources for GIS The primary data sources for GIS include; first, web pages. The internet is a platform for accessing GIS data. This GIS data from the internet is in digital format. Again, it is necessary first to evaluate the quality of data found in Metadata before purchasing or downloading it as per the GIS project’s quality standard. Secondly are map sheets. The printed or hard copy maps documents are also sources of GIS data. They vary as per format, content, age, usage, media, scale and complexity but should be legible for providing direct measurements ...

What are the main data sources for GIS? Do some research and try to list Canadian sources (with their web addresses) for road data. Geographical Information System or GIS is a database system that have the capacity of analyzing spatially referenced data (ESRI). Any data with spatial attributes can be a source of GIS. Several processes in GIS are encoding, storage, processing and display of digitized maps (Understanding GIS). Some of the Canadian websites that share free data are the Canadian GIS and Geomatics, ESRI Canada, National Resources Canada, GeoBase, GeoGratis, and some other Canadian websites that offer open ...

1.0 Introduction Many sports played across the world that involves throwing, hitting and kicking are done so using a ball. However, many parameters such as humidity, materials of manufacture of the ball, size of the ball, etc. control the movement of the ball in air. Research on golf balls and tennis balls reveal their aerodynamic properties and the various parameters affecting their flight. The effect of seams on a baseball on the flight has been evaluated along with the relationship between rotation and lateral forces (Watts & Sawyer 1987). Similar studies have also been conducted on cricket balls, rugby balls, volleyballs ...

The cumulative frequency gives us the number of observations lying below or above a particular value of a variable. Cumulative frequencies are of two types : a) Less than type, b) more than type. - Less than type: We calculate the number of observations lying below each value of the variable. As the values increase we keep on adding the corresponding frequencies to get the cumulative frequency.

Example 1: The weights of 36 pumpkins from a vegetable market are recorded and presented as a frequency distribution table :

The table shows that there are 6 pumpkins weighing 4 kg, but there are 30 pumpkins weighing 4kg or less. Similarly there are 35 pumpkins having weight not more than 6kg.

This can be represented graphically as in figure 1.

Asepsis

Microorganisms are the tiny microscopic structures that cannot be seen with naked eyes. They are present on all the living things and also in the environment. Some of these microorganisms are non pathogenic that is they do not cause any disease. However, many of the microorganisms are pathogenic in nature. The pathogenic microorganisms can cause disease or infections. Absence of these pathogenic microorganisms is known as asepsis.

Importance of asepsis

Asepsis is usually carried out in the laboratory mostly while dealing with microorganisms. The techniques used to carry out asepsis are known as aseptic techniques. If aseptic conditions are not maintained in ...

Integer Programming

The problem of integer programming (IP) refers to a problem in which some or all variables must take integer values. In the case when the constraints and the objective function are linear dependence problem is called an integer linear programming problem. Otherwise, if at least one non-linear dependence will be, it will be the integer nonlinear programming problem. Of particular interest to the problems of the IP due to the fact that in many practical problems, we need to find an integer solution due to a discrete series of values ​​of the variables. In the field ...

Introduction

When objects are accelerated, inertia-forces are generated. This is the case with rotating machine elements. The design of such parts must ensure that they perform their intended work under all the existing combinations of service loads and rotational forces or inertia forces. The rotation of a machine element results in an external vibrating force. The shaking force disturbs the supporting frame of the machine and the adjacent parts. It is also worth to note that the vibration generated by rotating machine elements and consequently the associated noise is also a serious problem to the machine operators. Therefore, it is very important ...

Abstract

Ginkgo Biloba extract is widely used by older adults as a cognitive enhancer although efficacy studies show inconsistent results. A review was done of three quantitative studies with the hypothesis that once-daily use of Ginkgo Biloba does not help improve the memory of adults aged 50 years or older. One article was a clinical trial on the differences in electrical activity in the brain when Ginkgo Biloba or placebo is used during a working memory test. The second article is also a clinical trial that determined the efficacy of Ginkgo Biloba in reducing cognitive and therefore memory decline in patients with early-stage dementia. ...

Introduction Marcello (2002) define Stonehenge as a prehistoric monument found in the UK and its one of the most famous sites in the entire world. Stonehenge of Geometry has been very crucial in helping discover various Mathematical truths. Its design shows the elegant and symbolism of numbers and geometry. Several years back surveyors and engineers understood and used this mathematical concept in construction of houses. Many of the Neolithic ancestors used the knowledge of geometry in building Stonehenge. This is to mean that the mathematics which was used by that time in building showed much of the geometrical form of ...

Geometry of Plane Shapes

This is a branch of mathematics that is basically concerned with shapes and their properties. The shapes involved here are plane shapes (geometry) which have to do with lines, circles, triangles, rectangles, squares and other polygons which include pentagons, hexagons, octagons etc. other types of shapes are solid geometry (including cubes, pyramids, prisms) The general properties of planes shapes also called flat surfaces are that we can calculate their areas and perimeter or distance around the shape. We however cannot find their volumes and their total surface areas because their thicknesses (or widths or breadth) are really negligible compared ...

1. Natural disaster due to landforms and processes: Earthquake Magnitude 9.0 Location: Tohoku, Japan/March 11, 2011, Geologic/geomorphic setting: Japan sits right where it is affected by four tectonic plates. The four plates are the Pacific Plate to the east, the Philippines Sea Microplate to the south, the Eurasian Plate to the west, and the North American Plate to the north. Triggers: The earthquake hypocenter is where a slip occurs on a fault plane between the North American and Pacific Plates. The Earth Observatory Singapore explained that a megathrust occurred because the edges of the two plates stuck together causing ...

In naming this piece, Damien Hirst compels us to confront the message of End Game: our vanity and mortality. Hirst draws from the vanitas (Latin for vanity) genre of paintings of the 17th century, which depicted decaying animals and fruits and human skulls. The effect was to remind us of the temporality of all life. Hirst too wants us to stand face to face with our own personal “end game.” End Game is a large-scale sculpture. It measures 77 X 148 X 20 inches and stands up along a wall at one end of the gallery. The main component of ...
