The use of simulation to predict building energy performance has been shown to have significant benefits in terms of reducing energy consumption and greenhouse gas emissions. However, in terms of implementation, the process can be disjointed and messy, with a lack of integration between architects and engineers. For the process of creating a building energy simulation to be more efficient, a seamless transition from an architectural design to an energy model is required. This paper highlights some of the practical issues manifest in the process of data exchange for energy analysis. It presents a proposed workflow for the exchange of …
Automatic Power Management For Instructional Computers At Humboldt State University: A Calculation Of Potential Energy Savings And Greenhouse Gas Emissions Reductions, Nicholas F. Flenghi
Automatic Power Management For Instructional Computers At Humboldt State University: A Calculation Of Potential Energy Savings And Greenhouse Gas Emissions Reductions, Nicholas F. Flenghi
Projects
Computers consume an estimated 5,610 GWh per year in California alone. Much of that energy is consumed by computers that are not being used. In this project, detailed user login data are used to estimate the energy consumption of instructional computers at Humboldt State University (HSU) over the course of one semester. The data are also used to estimate the potential energy savings from automating the shutdown process. Potential cost savings and greenhouse gas (GHG) emissions reductions resulting from implementing an automatic-shutdown power management plan are also calculated.
There are approximately 1,000 computers used for teaching and learning purposes at …

Module 2: Solar Powered Cricket Lab & Engineering Guest Speaker, Lindsay Snowden
ENERGY Research and Lesson Plans
Students will participate in a Solar Panel Cricket lab to determine which environmental condition would allow for the solar panel to produce the most power. The three conditions are inside, inside with a flashlight, or outside in the sun. The students will complete a correlating lab worksheet. Students will also ask questions and hold discussions with the guest speaker. Students will actively participate while the guest speaker is presenting.

Suspended Graphene-Based Gas Sensor With 1-Mw Energy Consumption, Jong-Hyun Kim, Qin Zhou, Jiyoung Chang
Suspended Graphene-Based Gas Sensor With 1-Mw Energy Consumption, Jong-Hyun Kim, Qin Zhou, Jiyoung Chang
Department of Mechanical and Materials Engineering: Faculty Publications
This paper presents NH3 sensing with ultra-low energy consumption for fast recovery and a graphene sheet based on a suspended microheater. Sensitivity and repeatability are important characteristics of functional gas sensors embedded in mobile devices. Moreover, low energy consumption is an essential requirement in flexible and stretchable mobile electronics due to their small dimension and fluctuating resistivity during mechanical behavior. In this paper, we introduce a graphene-based ultra-low power gas detection device with integration of a suspended silicon heater. Dramatic power reduction is enabled by a duty cycle while not sacrificing sensitivity. The new oscillation method of heating improves …
Relative Cross Track Error Calculations In Asabe/Iso 12188-2:2012 And Power/Energy Analysis Using A 20 Hp Tractor On A Fully Electric Drivetrain, Joseph D. Rounsaville
Relative Cross Track Error Calculations In Asabe/Iso 12188-2:2012 And Power/Energy Analysis Using A 20 Hp Tractor On A Fully Electric Drivetrain, Joseph D. Rounsaville
Theses and Dissertations--Biosystems and Agricultural Engineering
ASABE/ISO Standard 12188-2 provides test procedures for positioning and guidance systems in agricultural vehicles during straight and level travel. The standard provides excellent descriptions of test procedures, however it does not provide detail on methods to carry out the calculations necessary to calculate relative cross-track error (XTE), which is the primary measurement used to judge accuracy of the system. The standard was used to estimate the guidance accuracy of a relatively low-accuracy vehicle at 1.25 and 0.5 m s-1. At 1.25 m s-1, a nearest point calculation overestimated mean XTE by 0.8 cm, or 8.2%. The …
