This community contains the theses of the Department of Agricultural and Biosystems Engineering.
A Master of Science is offered through the College of Engineering. Areas of specialization for Agricultural and Biosystems Engineering include machine vision, biomaterials processing, soil and water engineering, structures, and machine design.
Due to copyright restrictions, the collection contains both open access and university access theses and dissertations. University access items are only available to SDSU users, and on-campus visitors. Non-SDSU users wishing to access restricted materials may request items through their institution’s interlibrary loan services.
