Bioprocess Engineeinrg lab  

Engineering Properties & Processing

The laboratory space in room 118 is used primarily for bioprocessing research and portions of several teaching laboratories are also conducted in the space. Research related to lipid extraction from grain sorghum, production of protein and chitosan films, and modeling heat transfer and microbial growth in meat products is conducted in this lab. Instructors who use the laboratory space for teaching could include the topics of engineering properties of biological materials, food processing unit operations and agricultural products processing and handling. Major equipment available in the lab includes two controlled environmental chambers, three chemical hoods, a freeze dryer, centrifuge, two drying ovens, three cross-flow grain dryers, four balances, three freezers and two refrigerators.

Machine Vision

The Machine Vision Laboratory contains special workstations and equipment for developing and testing machine vision applications. The lab has been used for imaging and plant (weed) detection and species identification, and other machine vision projects with Agronomy Horticulture and Food Technology. Equipment includes 700 MHz, 3.0 GHz and 3.2 GHz Windows XP workstations with commercial and custom image processing programs, Visual Basic®, Visual C++, MatLab®, LabView®, Neural-Network and Fuzzy logic toolboxes, and SAS® statistics. A controlled-lighting room provides standard 5500K daylight room lighting and a special stand for studying light sources for imaging. Digital cameras can be accessed or controlled from a nearby computer. Equipment includes several light intensity and color temperature meters. The laboratory has a spectro radiometer, standardization panel, digital cameras, and scanners, including matched pairs of CCD black-and-white and color video cameras. The lab has a selection of precision optical band pass filters. Projects have ranged from machine vision applications (particularly weed detection) to seed spacing measurement and soil sensors development. Other projects were related to the departmental undergraduate and graduate programs.

Interactive computer lab  

Instructional Computing

Undergraduate and graduate students have access to a modern computer laboratory. This general laboratory has 26 Windows XP workstations (3.0 and 1.8 GHz) with LCD monitors along, with high-speed laser black-and-white and color printing, and a flatbed scanner. Each workstation has office tools and specialized engineering design and mechanized systems software. A Windows 2003 (active directory) domain server provides for individual student accounts, private storage, and daily backup. The lab is equipped with a digital projector and screen for software instruction and formal demonstrations.

All departmental computers operate on a network, connecting the entire campus and outside world through the internet. UNL faculty, staff, and students communicate using electronic mail, within the University and around the world, and have access to University and world-wide library sources. Students also have access to individual course materials 24-hours per day through the Academic Portal, a web-based support system for teaching. In addition, an adjacent student project design room has computer support and space for student projects. The department's full-time computer specialist is responsible for the daily operation of the network, account administration, and is available to solve computer problems. Instructional computing, video-based visualizers, and projected multimedia presentations are provided in the five classrooms in L. W. Chase Hall.
