The goal of this project is to develop an demonstrate the feasibility of computer-based, multimedia instruction to facilitate the acquisition of difficult to learn mathematics principles. The goal will be accomplished through the design and development of a multimedia interface that uses audio prompts, interaction graphics, and text displays to guide learners through problem solving activities. ...

Protein is the most expensive component comprising a catfish feed; thus, a reduction in feed cost can most likely be achieved by either reducing the concentration of dietary protein, by using less expensive plant proteins, or by a combination of these factors. Feedstuffs of animal origin are expensive yet they are generally considered to be essential in catfish feeds. If low-protein, all plant-p ...

THE ENVIRONMENT SURROUNDING CONFINED ANIMALS DIRECTLY AFFECTS THE PRODUCTIVITY OF THE LIVESTOCKINDUSTRY. A GOOD VENTILATION SYSTEM, WHICH CONTROLS THIS ENVIRONMENT, IS ESSENTIAL FOR MANTAINING THE HEALTH AND WELFARE OF ANIMALS AND WORKERS IN THE LIVESTOCK BUILDINGS. HOWEVER, THE DESIGN AND MANAGEMENT OF SUCH A SYSTEM IS A COMPLICATED PROCESS. IT INVOLVES OPTIMIZATION OF VARIOUS GOVERNING PARAMETER ...

Cooling and drying of feed pellets are the most important operations in the feed manufacturing industry. These operations are carried out simultaneously, in a single machine, by passing ambient air through a moving bed of pellets. However, simultaneous control of both these processes is very difficult. Overdrying of pellets is a common problem that costs several million dollars to feed processi ...

AUTOMATED PLANT PROPAGATION BY CUTTAGE (PREPARATION AND PLANTING OF CUTTINGS) REQUIRES AN EFFICACIOUS, NON-HUMAN MEANS OF SENSING THE ORIENTATION OF EACH CUTTING. CURRENT EXPERIMENTAL VIDEO BASED SYSTEMS ARE TOO EXPENSIVE, SLOW, UNRELIABLE, AND/OR COMPLEX FOR WIDESPREAD USE BY THE COMMERICAL NURSERY, FLORIST, AND FORESTRY INDUSTRIES. PRELIMINARY STUDIES INDICATE THAT TACTILE ARRAY SENSING OF CUTTI ...
