Trigeneration systems, also known as Combined Cooling, Heating, and Power (CCHP), simultaneously provide electric, mechanical, and thermal energy. Compared to traditional systems, they deliver higher fuel efficiencies as waste heat from engine coolant and/or exhaust is recovered and utilized. In heating, ventilation, and air condi-tioning (HVAC) systems, the recycled heat may be used to provide space heating, water heating, and cooling (through absorption chillers). As there are more practical applica-tions for the recovered heat during the heating season than the cooling season, trigenera-tion systems tend to be more attractive in colder weather. This research focuses on the PowerAire 65 by …

Distributed energy, also district or decentralized energy is generated or stored by a variety of small, grid-connected devices referred to as distributed energy resources, or distributed energy resource systems. The Distributed Generation (DG) systems can increase energy system reliability, reduce peak power requirements, and improve energy infrastructure resilience. In this study, a DG system using renewable energy sources and energy storage has been introduced for the whole University of Alabama at Birmingham (UAB) campus. The energy sources for this DG system are photovoltaic arrays, a natural-gas-powered Internal Combustion Engine (ICE), and wind turbines. The energy storage component used in this …

Renewable energy continues to proliferate throughout the world as costs decrease and the public desire for clean energy rises. These sources are intermittent by nature, providing added complexity to its integration with existing grid infrastructure. This paper proposes an iterative pricing and energy consumption strategy between a utility and home energy management (HEM) system, acting on behalf of homeowners, with the goal of easing this integration while also decreasing homeowner energy costs, increasing utility profit and minimizing utility energy storage requirements. The strategy begins with a day-ahead energy cost profile developed by the utility using a mix of traditional and …

Home energy management systems encourages the users coupled to the grid to modify their electricity consumption in response to fluctuating electricity rates. The purpose of this research is to develop a distributed home energy management system for the end-user to employ in order to minimize costs. Using the home energy management system, the end-user will find and optimal start times for their appliances in response to varying electricity prices. First, the cost for each user and time-constraints for the appliance is modeled. Then, an iterative greedy algorithm is employed by the user to create an appliance schedule. The only variable …

Mallet percussion instruments such as the xylophone, marimba, and vibraphone have been produced and tuned since their inception by arduously grinding the keys to achieve harmonic ratios between their 1st, 2nd, and 3rd transverse modes. In consideration of this, it would be preferable to have defined mathematical models such that the keys of these instruments can be produced quickly and reliably. Additionally, physical modeling of these keys or beams provides a useful application of non-uniform beam vibrations as studied by Euler-Bernoulli and Timoshenko beam theories. This thesis work presents a literature review of previous studies regarding mallet percussion instrument design …
