Optimization Of Acid Production In Food Waste Via Anaerobic Respiration, Charles Daniels, Raymond Red Corn, Abigail S. Engelberth PhD. 2014 Purdue University

Optimization Of Acid Production In Food Waste Via Anaerobic Respiration, Charles Daniels, Raymond Red Corn, Abigail S. Engelberth Phd.

The Summer Undergraduate Research Fellowship (SURF) Symposium

According to the Food and Agriculture Organization of the United Nations, one third of all food produced in world is wasted; 1.63 * 109 metric tons of nutrition is lost to transportation, contamination, or neglect every year (FAO 2013). This wasted food, however, could be repurposed as a substrate for microbial conversion into useful chemicals. This research is aimed at finding the optimal conditions for bacterial colonies to generate volatile fatty acids (VFAs): resources that are used as solvents, medicines, and chemical intermediates usually generated from petroleum based resources (Drumright et al., 2000) (Roscher 2000) (Kolt et al., 2007 ...


Portable Pneumatic Demonstrator For Stem Education, Joe Chege, Tyler Helmus, John Lumkes 2014 Purdue University

Portable Pneumatic Demonstrator For Stem Education, Joe Chege, Tyler Helmus, John Lumkes

The Summer Undergraduate Research Fellowship (SURF) Symposium

This project involves the development of a compact and portable pneumatic demonstrator. Using two pneumatic actuators and four solenoid valves, we are able to move an arm on both the X and Y-axes; one actuator for each range of motion. The setup also employs an air pump and a tank to maintain pressure for the actuators. On the actuators there is an arm that holds a camera, a stepper motor and an electromagnet. The stepper motor raises and lowers the electromagnet which is used to pick up objects. The camera is used to automatically identify objects for when the demonstrator ...


Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D. 2014 Rochester Institute of Technology

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D.

Journal of Applied Packaging Research

Distribution packaging design often relies on cushion curves to determine required material thickness needed for product protection during shipment. The material thickness chosen based on cushion curves establishes overall package size, a key determiner of logistics costs. Cushion curves are constructed by dropping a mass onto a cushion, and interpreting the resulting shock pulse deceleration. The reported deceleration can be highly influenced by applying a “filter” to the shock pulse, a useful standar d prac - tice that removes unwanted high frequency elements superimposed on top of the basic shock pulse shape. Standard test methods for generating cushion curves generally do ...

Automated Image Interpretation For Science Autonomy In Robotic Planetary Exploration, Raymond Francis 2014 Western University

Automated Image Interpretation For Science Autonomy In Robotic Planetary Exploration, Raymond Francis

University of Western Ontario - Electronic Thesis and Dissertation Repository

Advances in the capabilities of robotic planetary exploration missions have increased the wealth of scientific data they produce, presenting challenges for mission science and operations imposed by the limits of interplanetary radio communications. These data budget pressures can be relieved by increased robotic autonomy, both for onboard operations tasks and for decision- making in response to science data.

This thesis presents new techniques in automated image interpretation for natural scenes of relevance to planetary science and exploration, and elaborates autonomy scenarios under which they could be used to extend the reach and performance of exploration missions on planetary surfaces.

Quantitative Data Extraction Using Spatial Fourier Transform In Inversion Shear Interferometer, Yangzen Li 2014 Rose-Hulman Institute of Technology

Quantitative Data Extraction Using Spatial Fourier Transform In Inversion Shear Interferometer, Yangzen Li

Graduate Theses - Physics and Optical Engineering

Currently there are many interferometers used for testing wavefront, measuring the quality of optical elements, and detecting refractive index changes in a certain medium. Each interferometer has been constructed for a specific objective. Inversion shear interferometer is one of them. Compared to other interferometers, it has its own advantages, such as only being sensitive to coma aberration, but it has some limitations as well. It does not allow use of phase shifting technique. A novel inversion shear interferometer was invented using holographic lenses. By using the spatial carrier method, phase information of the wavefront was extracted. The breakthrough of the ...
