Faculty News for March

ABE has been awarded a $13,500 instructional equipment grant by the College of Agriculture to bring Android tablets and apps into the classroom and into the field (at least, nearby fields). Welcome to the 21st Century!

Drs. Frankenberger, Ess, Buckmaster, and Larry Theller are involved. The courses that will use this technology include ASM 105 (Ag Systems Computations and Communication), ASM 215 (Surveying), ASM 540 (GIS Applications), and ASM 591 (Technology for Precision Agriculture). This technology will allow students to combine global positioning systems (GPS) data acquisition with real-time GIS processing.

Maha Student News

After five years at the Maha Fluid Power Lab, Matteo successfully defended his PhD thesis. Matteo contributed a great research work to Maha and we are sad to see such a valuable member go, but we give our congratulations and wish him best of luck in the future! 


Maha welcomes new members Guido Francesco Ritelli (Visiting Researcher), Juan Pedro Gomez Virgilio (Visiting Researcher), and Wei Shen (Visiting Researcher) to the lab. We wish all of them the best of luck!

The Maha Fluid Power Lab is proud to present the achievements of the past year. The annual report is available for download at:

Students involved in GWG (Graduate Women's Gatherings) visited the Maha lab on Feb 17th. Monika gave her life time story to the students and also Andrew gave them a lab tour.





The Maha Fluid Power Lab is looking for undergraduate research interns during the summer of 2012. The following projects are available for this Summer:

  • Theoretical and experimental study of a hydraulic pump's structure vibration and acoustics
  • Design of a test rig to measure fluid film thickness
  • Development of a new test stand for thermal measurements on axial piston machines
  • Measurement and modeling of hydraulic pumps
  • Friction force measurements in the piston cylinder interface of axial piston machines
  • Experimental research supporting the development of a hydraulic hybrid excavator system
  • Prognostics system for displacement controlled multi-actuator hydraulic hybrid machines
  • Electro-hydraulic power steering system controller
  • Instrumentation and evaluation of a large off-highway vehicle

The full description of the projects is available at:
