A comprehensive model is developed to estimate and predict the fuel consumption and emissions by domestic commercial aviation in the Continental United States. Most of the existing fuel consumption and emission models are limited in their ability to predict the annual fuel burn for air transportation at the national level. For example, those models either require real track data or are developed only to model single flight scenarios.  The model developed in this thesis is part of a software framework called the Transportation Systems Analysis Model (TSAM). The model has the capability to estimate fuel consumption and emissions for millions of domestic flights in a year in the continental U.S. TSAM is a nationwide, long-distance, multimodal travel demand forecast model developed at Virginia Tech. The model enables TSAM to quantify fuel and emission metrics for various modes of transportation. The EUROCONTROL Base of Aircraft Data (BADA) is employed as the Aircraft Performance Model to simulate individual flight profiles and calculate fuel burn rates. Fuel consumption on the ground (taxi mode) is estimated separately. Different operational conditions like wind states, terminal area detour, cruise altitude and airport elevation are considered in the model. Emissions of HC, CO, NOx and SOx are computed inside the Landing/Take-off (LTO) cycle based on the fuel consumption estimate, while greenhouse gas of CO2 is calculated for the complete flight cycle. / Master of Science

This work is focused on the workload management of data warehouses based on Teradata technologies using Active System Management architecture. Objectives of this work are to characterize and analyze Active System Management architecture and types of rules, used in the workload management of Teradata data warehouses. These objectives have been achieved by a search of available resources and their subsequent analysis. Informations obtained from the analysis were empirically verified on a particular instance of a data warehouse and their synthesis is presented in this work The contributions of this work are in the documentation of technology that is currently not well known and widespread in the Czech Republic. Another contribution is identification of risks, drawbacks and presentation of recommendations in the workload management using Active System Management based on empirical tests. The repeatable implementation procedure based on induction has been proposed in the work. Maturity of the architecture for a production environment is evaluated. The work is hierarchically divided into several chapters that are dedicated to Teradata database technologies, workload management, Active System Management and implementation procedure. The first three chapters are focused on theory, however, they also contain practical informations related to the processed theory. The latter chapter is focused practically, therein is designed a repeatable Active System Management architecture implementation procedure.
