The document summarizes updates to the 2010-2011 National Engineering Design Challenge involving building windmill devices to perform tasks. Key changes include measuring average electrical power output over time using automated equipment rather than lamps, requiring teams to measure and report the mass of their device, and extending devices over table edges and onto the floor. Teams must now submit a cost and labor summary as part of their academic display. The performance criteria for tasks raising a mass, powering a vehicle, and responding to wind direction changes remain the same.

The document presents an optimization-based algorithm for energy disaggregation from low frequency smart meter data. The algorithm formulates energy disaggregation as a least squares minimization problem with penalty terms to impose piecewise constant appliance usage profiles. The objective function fits aggregate consumption while penalizing frequent on/off switching. Constraints ensure each appliance operates at one level per time interval, maximum energy usage over time is not exceeded, and minimum daily usage is satisfied on activation days. The algorithm aims to address challenges of ultra-low frequency smart meter data for energy disaggregation.

It motivates the need for combined aero-structural design approaches due to strong couplings between aerodynamic shape, structural sizing, and cost. Three aero-structural design algorithms are presented: monolithic optimization with load updating, optimization with pre-assumed aerodynamic shapes, and external aerodynamic internal structure optimization. Multi-level structural optimization is also discussed to improve constraint satisfaction.DESIGN OPTIMIZATION OF WIND TURBINE BLADE
The objective of this project is to design a wind turbine that is optimized for the constraints that come with residential use. The main tasks of this project are:
> To study the design process and methodology of wind turbine
> Derive the Blade Element Momentum (BEM) theory then use it to conduct a parametric study that will determine if the optimized values of blade pitch and chord length create the most efficient blade geometry
> Analyse different air-foils to determine which one creates the most efficient wind turbine blade.
vertical axis turbine test results
1. Two tests were conducted on a vertical axis wind turbine: one with just the rotor, and one with a conveyor placed in front of the rotor.
2. Power production increased by 50% over 13 m/s wind speed and 30% below 13 m/s when the conveyor was added.
3. Calculations show that with a larger, optimized conveyor and increased rotor diameter and length, power production could reach the goal of 2360 watts at a wind speed of 10 m/s.

This study experimentally investigated the performance of a flat plate solar air heater at different air mass flow rates. Tests were conducted to measure energy and exergy efficiency. It was found that increasing the mass flow rate from 0.036 kg/s to 0.042 kg/s resulted in a 20% increase in energy efficiency and a 36% increase in exergy efficiency. The maximum daily energy efficiency of 56% occurred at a mass flow rate of 0.042 kg/s, while the maximum daily exergy efficiency of 1.46% also occurred at this highest mass flow rate. Increasing the mass flow rate improved the performance of the solar air heater.
