AB E 422.3
Modeling of Biosystems
1(3L-1.5T)
Prerequisite(s): AB E 324 and 327.

The student will be introduced to the concept of computer simulation as an analytical tool for understanding, designing and testing biology-related systems. Content includes introduction to systems modeling, classification of models, elements of dynamic simulation models, analytical models based on equilibrium, modeling growth and population dynamics, compartment models, feedback in biological systems and feedback mechanisms and stability of biological systems. Mathematical optimization and reliability analysis techniques are introduced.

AB E 431.3
Irrigation System Design
1(3L-1.5P)
Prerequisite(s): AB E 212 and C E 319.

Engineering and hydrologic principles are applied to design of modern irrigation and drainage systems. Soil-plant-water relationships important to understanding water needs are emphasized.

AB E 432.3
Soil and Water Conservation
1(3L-1.5P)
Prerequisite(s): AB E 212 or SL SC 220.

A study of the effects of management practices upon degradation and sustainability of agricultural, forest, wetland, and other land and water resource systems common to the Prairies. Topics include environmental factors governing soil development; degradation including erosion, salinization, soil organic matter depletion, soil compaction, and water contamination; preservation, mitigation and construction of wetlands; water conservation techniques; good agricultural, forestry and land management practices; economic and social-political implications of degradation versus conservation.

AB E 441.3
Design of Enclosed Environments
2(3L-1.5P)
Prerequisite(s): Completion of 90 credit units towards the B.E. degree.

This course emphasizes the physical aspects of environment control systems for agricultural buildings. The student will experience engineering designs involving greenhouses, animal shelters and vegetable storages. Emphasis is on solution of real-world problems, which depend upon making reasonable assumptions, integrating knowledge from more than one source, and interpreting mathematical results in terms of physical systems. Some use is made of computer programs. Laboratory periods are used for tours to buildings to observe environment control systems and for work on group design projects.

AB E 451.3
Design of Agricultural Machinery Systems
2(3L-1.5P)
Prerequisite(s): AB E 324.

Study of agricultural and other off-road machinery with special attention to the functional design requirements of various machine operations, cost analysis, machinery selection and testing. Topics include tillage force analysis, tillage tools, mechanisms for metering and applying seed, fertilizer and pest control chemicals, harvesting methods and machinery, hydraulic and other methods of transmitting power and controlling machines, application of computer aided design and finite element method in design analysis.

AB E 452.3
Machines in Biosystems: Current Topics
2(3L-1.5P)
Prerequisite(s): AB E 313.

Introduction to specialized components and analyses relevant to mechanized systems for production and processing of biological materials. Emphasis is on understanding the function of components within systems. Students will be able to recommend application of these components in a variety of situations and will develop conceptual designs for some of the components.

AB E 462.3
Agricultural Materials Handling
2(3L-1.5P)
Prerequisite(s): AB E 323 and 327.

A study of processes involved in conveying, storing, drying, cleaning and sorting agricultural products. Analysis and design of machines used for conveying bulk solids and liquids. Theory and practice of drying for grain and forage crops. Moisture and quality control in storage and transport.

AB E 481.3
Sustainability and Environmental Assessment
2(3L-3P)
Prerequisite(s): Completion of 90 credit units of university study.

A study of the principles of sustainable development and the process of environmental impact assessment with emphasis on Prairie agricultural and industrial settings. Case studies are used to illustrate the EIA process in engineering design of environmental control measures. Concepts of integrated resource management are analyzed as the basis for making linkages between protecting the environment, economic development and public participation.

AB E 482.3
Design for Waste Utilization
1(3L-1.5P)
Prerequisite(s): Completion of 90 credit units of university study towards the B.E. degree.

The design of systems and equipment for processing and utilization of wastes generated by the bioresource industries, including primary agriculture, food processing, and forestry. Pollution problems caused by these industries are examined and opportunities for recycling and utilization of wastes are identified. Emphasis is on land as opposed to surface water as a receptor of organic wastes. A comprehensive strategy is developed for approaching pollution control and waste product utilization problems. Students are expected to integrate sociological, regulatory, economic, biochemical and technological considerations in exploring waste treatment and utilization options. Students will work in teams to conduct an industrial waste survey and a feasibility study of waste reduction and enhanced waste utilization for a specific local industry, farm, or processing plant.

AB E 495.3
Design Capstone II
2(3P)
Prerequisite(s): AB E 395.

A continuation of AB E 395 in a self-directed course. Students perform the analysis associated with the design problem and are able to specify a design solution at the end of the course. Students must submit a comprehensive report, describing the design solution. The final design solution is also presented to the faculty and staff in the Department of Agricultural and Bioresource Engineering in the format of poster and oral presentations.
