The diagrams illustrate some changes to a small island which has been developed for tourism. It is clear that the island has changed considerably with the introduction of tourism‚ and six new features can be seen in the second diagram. The main developments are that the island is accessible and visitors have somewhere to stay. Looking at the maps in more detail‚ we can see that small huts have been built to accommodate visitors to the island. The other physical structures that have been added are

We don’t say data structurehere and see the difference. Graphs mean to store and analyze metadata‚ the connections‚ which present in data. For instance‚ consider cities in your country. Road network‚ which connects them‚ can be represented as a graph and then analyzed

Trip to the Store: Profile Essay I am at one of the biggest super markets in Modesto‚ WinCo Foods. This store is one of the cleanest‚ organized‚ and best customer services I see ever since it first opened up several years ago. I go to the store twice every week.

He smiles and says “Welcome to Winco‚ how is your day?” he sounds as if he’s a real good friend of mine who I known for years. Anyway‚ I go

Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs

Introduction in Graph Theory (BASIC CONCEPTS) BASIC CONCEPTS We used decision trees in Unit DT and used them to study decision making. However‚ we did not look at their structure as trees. In fact‚ we didn’t even define a tree precisely. What is a tree? It is a particular type of graph‚ which brings us to the subject of this unit. What is a Graph? There are various types of graphs‚ each with its own definition. Unfortunately‚ some people apply the term “graph” rather loosely‚ so

The bar chart illustrates the unemployment rate in Germany compared to the unemployment rate in Ireland. The y-axis shows the rate of unemployment which is defined by the number of unemployed persons as a percentage of the labor force. On the x-axis you can read the year. In 2000‚ 8 per cent of the German workforce was unemployed‚ which was twice as high as Ireland. Unemployment in Germany declined slightly in 2001. However‚ after this the unemployment rate rose steadily over the next four years
