The Methodology For Integrating Robotic Systems In Undeground Mining Machines, Peter Kolapo
The Methodology For Integrating Robotic Systems In Undeground Mining Machines, Peter Kolapo
Theses and Dissertations--Mining Engineering
Roof bolting is a critical operation in ensuring the safety and stability of underground mines by securing the roof strata with bolts. The process involves moving and manipulating heavy tools while being vigilant about the safety of the area. During the installation of roof bolts, operators are exposed to hazardous conditions due to challenging working conditions in underground mines, extensive working hours, and demanding shift schedules leading to personnel fatigue and influencing operators to take shortcuts that may increase the risk of injuries and fatal accidents. The successful completion of roof bolting tasks depends heavily on operator judgment and experience …
Automated Solid-Substrate Cultivation Of The Anaerobic Bacterium Clostridium Thermocellum, Mathew J. Ruwaya
Automated Solid-Substrate Cultivation Of The Anaerobic Bacterium Clostridium Thermocellum, Mathew J. Ruwaya
Theses and Dissertations--Biosystems and Agricultural Engineering
The organism Clostridium thermocellum grows on cellulosic substrates and produces ethanol, acetate, lactate, formic acid, and CO2. The organic acids produced alter the growth environment in which the bacteria grows and ultimately inhibit bacterial growth. One method which has been used successfully to maintain the system at acceptable growth conditions is to intermittently flush out the spent media and metabolic products and replace with new fermentation media. Our goal was to design and build an automated system that will automatically flush the spent media from the growing culture and resupply new media without manual intervention. An automated control …

Survey Of Welding Processes, Theodore Hopwood Ii
Kentucky Transportation Center Research Report
The current KYTC “SPECIAL PROVISION NO. 4 WELDING STEEL BRIDGES” prohibits the use of welding processes other than shielded metal arc welding (SMAW) and submerged arc welding (SAW). Nationally, bridge welding is codified under ANSI/AASHTO/AWS D1.5M/D1.5:2002 Bridge Welding Code. That document allows the use of other welding processes including flux core arc welding, gas metal arc welding, electroslag welding and electrogas welding after passing qualification tests.
Both the KYTC Special Provision and the Bridge Welding Code were reviewed. Representatives from 14 state highway agencies, fabrication shops, universities and welding equipment firms were questioned regarding the wider use of the welding …

Automated Sorting Of Oriented Tobacco Leaves, Larry G. Wells, M. J. Bader
Biosystems and Agricultural Engineering Faculty Publications
A mechanism has been developed which removes cured burley tobacco leaves from plants so that midribs are oriented parallel. A photosensor was utilized to count leaves as they were removed and a microprocessor determined the number of leaves allocated to each of three grades. Experiments indicated that 84% of leaves removed could be correctly sorted with a 2.4% material loss at an effective rate of approximately 2.4 times that of conventional methods.
