The efficiency of agricultural tractor transmission has been improved over the years, with new concepts such as Continuously Variable Transmission (CVT) and Full Powershift (FPS) evolving in advanced technologies. Both options seek to offer farmer greater operational results lower energy expenditure, necessitating studies assess effectiveness these technologies define best choice for each purpo...

Predicting the tractive limitations of locomotion gears is of critical importance in a robotic vehicle system on natural terrain. In particular, it is imperative for an unmanned mobile robot to avoid getting stuck in loose soil to retain its mobility. From this perspective, this paper attempts to theoretically predict the limitations of a typical wheel in such loose soil based on traditional so...

The synthesis, structure, and photophysical properties of a new family of trinuclear CuRe(2) chromophore-quencher complexes having the general form [Cu(pyacac)(2)(Re(bpy')(CO)(3))(2)](OTf)(2) (where pyacac = 3-(4-pyridyl)-acetylacetonate and bpy' = 4,4'-5,5'-tetramethyl-2,2'-bipyridine (tmb, 1), 4,4'-dimethyl-2,2'-bipyridine (dmb, 2), 2,2'-bipyridine (bpy, 3), 4,4'-dichloro-2,2'-bipyridine (dcl...

Inflatable robotic rovers (IRRs) are a promising concept for long-range exploration and access to high-risk areas on planetary surfaces. Through inflation or expansion of their locomotion elements, inflatable rovers can achieve extraordinary terrainability not possible by other conventional mobility systems while maintaining respectable travel speeds. Early work by NASA's Jet Propulsion Laborat...

In this design study, we introduce a novel class of digital audio effects that extend the recently introduced modal processor approach to artificial reverberation and effects processing. These pitch and distortion processing effects mimic the design and sonics of a classic additive-synthesis-based electromechanical musical instrument, the Hammond tonewheel organ. As a reverb effect, the modal p...
