Concepts for Data Modeling Crystal M. Reedus CIS 210 November 21‚ 2010 Abstract Data modeling techniques and methodologies are used to model data in a standard‚ consistent‚ predictable manner in order to manage it as a resource. Data models support data and computer systems by providing the definition and format of data. From a modeling perspective‚ the entire problem domain is viewed as a collection of class hierarchies (of objects) that are connected by messages. Data modeling techniques and

Modeling Gasoline Demand in the United States Economics 375 DePaul University‚ Chicago‚ IL 60601 June 13‚ 2012 Abstract This paper is an econometric approach to the estimation of price and income elasticities of gasoline demand in the United States from a translog model‚ and is based off of the most recent data available for use. This approach allows for variables to interact in a flexible yet instrumental way‚ providing for significant evidence that gasoline demand elasticities are construed

AIR DISPERSION MODELING: A Review of Available Point Source Dispersion Models Mathematical Modeling of Energy and Environmental Systems MANE6960H01 Spring 2013 Sarah Mahon INTRODUCTION Air dispersion modeling is the mathematical simulation of how pollutants disperse in the atmosphere. Dispersion modeling can be used for multiple purposes; including to model the path of volcanic ash in the atmosphere after an eruption‚ to model the plume of pollutants emanating from a coal-burning electricity

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

Stress in Life-Span Development Stress is an issue people deal with from childhood to adulthood. Stress is defined as “people’s physical and psychological reactions to demanding situations” (Nairne‚ 2006). The stress of a child may be at a different level than of an adult. However‚ anyone dealing with stress finds that it is not an easy concept. Stress is a part of life people deal with from time to time. The things that put stress in our lives‚ and how we handle the issue can depend on several

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

Yaghi‚ Samer Barakat commonly bump into each other by the automobile vehicle trailer during operation‚ and which can cause premature wear of trailer frame components [14]. During the life cycle of CTS quantitative changes are collected which leads to quantum leaps in operation suitability [6]. The description of CTS (a zero point of its life cycle) provides integrity of states. At the examination
