Journal ArticleDOI
A review of principle and sun-tracking methods for maximizing solar systems output
TL;DR: In this article, different types of sun tracking systems are reviewed and their pros and cons are discussed and the most efficient and popular sun tracking device was found to be in the form of polar-axis and azimuth/elevation types.
Journal ArticleDOI
Life-cycle assessment of a Solar Assist Plug-in Hybrid electric Tractor (SAPHT) in comparison with a conventional tractor
TL;DR: In this paper, a solar assist plug-in hybrid electric tractor (SAPHT) was evaluated and compared with an internal combustion engine tractor (ICET) in terms of the life cycle cost and environmental emissions.
Journal ArticleDOI

Mojtaba Naderi-Boldaji,Mojtaba Naderi-Boldaji,Reza Alimardani,Abbas Hemmat,Ahmad Sharifi,Alireza Keyhani,Mehari Z. Tekeste,Thomas Keller +7 more
TL;DR: In this article, a symmetric 3D finite element (FE) model for a single-tip horizontal penetrometer-soil interaction was developed and evaluated in ABAQUS/Explicit.
Journal ArticleDOI
3D finite element simulation of a single-tip horizontal penetrometer-soil interaction. Part II: Soil bin verification of the model in a clay-loam soil
Mojtaba Naderi-Boldaji,Mojtaba Naderi-Boldaji,Reza Alimardani,Abbas Hemmat,Ahmad Sharifi,Alireza Keyhani,Mehari Z. Tekeste,Thomas Keller +7 more
TL;DR: Naderi-Boldaji et al. as discussed by the authors developed a 3D finite element model for a single-tip horizontal penetrometer-soil interaction and two soil bin tests were conducted to evaluate the predictability of the model.
Journal ArticleDOI
Evaluation of alternative battery technologies for a solar assist plug-in hybrid electric tractor
TL;DR: In this article, the battery technologies available for use in solar assist plug-in hybrid electric tractors are compared. And the most suitable battery is determined based on the environmental life cycle effects and costs.
