Scale-Invariant Minimum-Cost Curves: Fair and Robust Design Implements

Four functionals for the computation of minimum cost curves are compared. Minimization of these functionals result in the widely studied Minimum Energy Curve (MEC), the recently introduced Minimum Variation Curve (MVC), and their scale-invariant counterparts, (SI-MEC, SI-MVC). We compare the stability and fairness of these curves using a variety of simple interpolation problems. Previously, we ...

Draft Force Inputs for Primary and Secondary Tillage Implements in a Clay Loam Soil

Tillage is the base operation in agriculture and its energy represents a considerable portion of the energy utilized in crop production. To measure the implement force requirements, are used dynamometers that are pull or three-point hitch types. In this research, an 82 kW research tractor equipped with an instrumentation system was used to determine the draft force inputs for four common tillag...

Minimum standards of anorectal manometry.

Functional disorders of the anus and rectum affect 10–20% of the population. Tests of anorectal function can provide useful information regarding the pathophysiology of disorders that affect continence and defecation or those that cause anorectal pain. Currently, several tests are available for evaluating anorectal function (Table 1). Often, they complement each other, but among the various tes...
