The four boxes full of text over there on the facing page are our first examples of UML. UML stands for Unified Modeling Language‚ and it’s the most common notation used for creating diagrams that describe object-oriented systems. It’s beyond the scope of this book to teach you everything there is to know about UML. However‚ we’ll be sprinkling in a lot of the really

us. Mathematical Modeling As we approach day to day life we often need to quantify the things around us‚ giving structure and numeric value to various situations. This ability to add structure enables us to make choices based on patterns we see that are weighted and systematic. With this structure in place we can model and even predict behavior to make decisions. Adding a numerical structure to a real world situation is called Mathematical Modeling. When modeling real world scenarios

There is a famous saying by the philosopher Heraclitus that there is nothing permanent in life except change. Every day is a different day from yesterday‚ and change is inevitable. Everything around us changes with the passage of time. Changes can be categorized under two main types‚ which are either beneficial or harmful. But I believe that most of the time‚ change is for the better than for the worse. From the olden days‚ when the time where our parents were merely just teenagers like us‚ till

Linear Modeling Project The purpose of this experiment is to determine whether a player’s statistics in baseball are related to the player’s salary. The sample set was taken out of 30 players who were randomly selected from the top 100 fantasy baseball players in 2007. We displayed the information with a scatter plot‚ and then determined with a linear equation the line of best fit. Along with the line of best fit we are going to analyze the Pearson Correlation Coefficient. This value is represented

Modeling the Greenhouse Effect Aim: The aim behind this experiment is to investigate the consequences of greenhouse gases by recording and comparing the change in temperature every 3 minutes of a flask filled with CO₂ in comparison to a flask filled with air. Introduction: The purpose of this experiment is to impersonate the greenhouse affect in our own lab by comparing and measuring the temperatures of greenhouse gases CO₂ compared to air. The experiment will recognize the difference

The importance of ICT Information and communication technology in primary and secondary schools‚ 2005/2008 This report is based on evidence from inspections of information and communication technology (ICT) between September 2005 and July 2008 in 177 maintained schools in England‚ as well as other visits to schools where good practice was identified. Part A describes the quality of ICT education in primary and secondary schools over this period. Part B considers how tackling assessment‚ vocational

133 Link manufacturing process and product life cycles Focusing on the process gives a new dimension to strategy Robert H. Hayes and Steven C. Wheelwright Although the product life cycle concept may have value for managers‚ its emphasis on marketing can make it inadequate for strategic planners. These authors point out that using a process life cycle can help a company choose among its various manufacturing and marketing options. Using the concept of a "product-process matrix‚" they show

WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called
