In this paper, we present a decentralized dynamic control algorithm for a robot collective consisting of multiple nonholonomic wheeled mobile manipulators (NH-WMMs) capable of cooperatively transporting a common payload. In this algorithm, the high level controller deals with motion/force control of the payload, at the same time distributes the motion/force task into individual agents by grasp ...

Powdery mildew [Podosphaera xanthii (Castagne) Braun & Shishkoff (syn. Sphaerotheca fuliginea auct. p.p.)] is now a common disease on watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] in the United States. In this study, the entire available U.S. Plant Introduction collection of Citrullus Schrad. ex Eckl. & Zeyh. species was evaluated for resistance to P. xanthii race 1W. The collection c...

We give an algebraic construction of the moduli space of irregular singular connections of generic ramified type on a smooth projective curve. We prove that the moduli space is smooth and give its dimension. Under the assumption that the exponent of ramified type is generic, we give an algebraic symplectic form on the moduli space. Introduction Moduli space of irregular singular connections are...

This meta-analysis employs a theoretical framework in quantitatively synthesizing empirical studies that investigate the effects of distance education (DE) versus classroom instruction on undergraduate student achievement. Analyses of 218 findings from 103 studies were conducted according to how media were used to support DE pedagogy. The results indicate that the effect sizes for synchronous i...

The effects of soybean seeding rates on evapotranspiration (ETc) and grass- alfalfa-reference crop coefficients (Kco Kcr) were investigated under five (185,250, 247,000, 308,750, 370,500 432,250 seeds ha−1) (62, 82, 103, 124 144% the recommended rate 300,000 ha−1 in experimental region) different irrigation strategies (i.e. full treatment [FIT], limited 75% FIT 50% rainfed treatment). Kco Kcr v...

THISARTICLE OFFERS A FORMAL READING of a classification scheme of international scope and long duration: the International Classijication ofDiseases (ID). The argument is made that this classification scheme retains many traces of its own administrative and organizational past in its current form. Further, it is argued that such traces operate normatively to favor certain kinds of narrative of ...
