Testing Feasibility Of Inductive Power Coupling For Modern Applications, Andrew Burman Jun 2016

Testing Feasibility Of Inductive Power Coupling For Modern Applications, Andrew Burman

BioResource and Agricultural Engineering

This project takes two bifilar tesla coils and uses them to find a % efficiency of power transfer as distances between the coils decrease. The reason this experiment is being conducted is to find possible implications for wireless charging of vehicles using similar style coils. This project conducted experiments on 60 Hz, 400 Hz, and 1 kHz frequencies for a small input signal. The general conclusion is that as the frequency increases more power can be transferred and higher efficiency of power transfer is seen. This project also concluded that it could be possible to get higher efficiency at a …


Design Of An Energy Efficient Virtual End Node Client Using Openadr2.0a And Smap, Kevin Navero Jun 2013

Design Of An Energy Efficient Virtual End Node Client Using Openadr2.0a And Smap, Kevin Navero

BioResource and Agricultural Engineering

Demand Response (DR) describes the set of actions taken to impose a reduction in electrical loads to stabilize the power grid and decrease costs. It is used when power grid emergencies or extremely high demand and congestion, threaten the electricity supply-demand balance. Automated Demand Response (ADR) describes a web-based control system that triggers DR events automatically by signaling other pre-programmed control systems. This project intends to use the OpenADR2.0 specifications provided by the OpenADR Alliance to construct an open source Virtual End Node (VEN) client to retrieve DR signals. The Simple Measurement and Actuation Profile (sMAP) software is also used …


Practical Irrigation Scheduling Program, Dominic Sween Jun 2013

Practical Irrigation Scheduling Program, Dominic Sween

BioResource and Agricultural Engineering

This senior project discusses the design, construction, and evaluation of an irrigation scheduling program that aids users in alfalfa irrigation management, with the potential for application with other crops. The program uses a very accurate irrigation prediction model that forecasts what the estimated irrigation need of each week will be, as well as the number of irrigations needed to satisfy the requirement. The model was found to predict the sum of the actual required weekly irrigation amount within less than 1% of the true value. The program was based off the single crop coefficient approach that was outlined previously by …


Design, Construction, And Evaluation Of An Automated Chicken Coop Door, Kyle Inks Jun 2012

Design, Construction, And Evaluation Of An Automated Chicken Coop Door, Kyle Inks

BioResource and Agricultural Engineering

This senior project takes a look into the design, construction, and evaluation of an automated chicken coop door. The idea and need for such a door came from my mother Jan Inks. The parameters for the project include, low production cost, easy installation on existing coops, sleek design, automatically open at a set time in the morning, and automatically close at a set time in the evening.


Design And Construction Of A Solar Operated Gate, Jacob Gardener Mar 2012

Design And Construction Of A Solar Operated Gate, Jacob Gardener

BioResource and Agricultural Engineering

This senior project discusses the design and construction of a solar operated gate. A solar panel is used to charge a battery, and then an inverter is used to run a garage door opener off the battery. The garage door opener operates a short lever arm which is connected to a longer lever arm which is connected to the gate. Each component and mounting mechanisms were designed and built to effectively provide the gate opening function. The finished product operates well, the gate opens in about 8 seconds after the button is pressed on the remote controller or wall mount …
