In this paper, a nonlinear adaptive heading controller is developed for an underactuated surface vessel with constrained input and sideslip angle compensation.The controller design is accomplished in a framework of backstepping technique.First, to amend the irrationality of the traditional definition of att nighthawk hotspot the desired heading, th
Abstract Autologous bone grafts are considered the gold standard grafting material for the treatment of nonunion, but in very large bone defects, traditional autograft alone is insufficient to induce repair.Recombinant human bone morphogenetic protein 2 (rhBMP-2) can stimulate bone regeneration and enhance the healing efficacy of bone grafts.The de
The in vitro fermentation efficiency of Cynodon nlemfuensis forage (star grass) and Leucaena leucocephala foliage (leucaena) and two energy sources (i.e.maize pure energy jeans and sugar cane molasses) mixture was evaluated.Mixture samples (1 g DM) were incubated for 24 h.All the mixtures were added with click here 500 mg of polyetilenglycol (PEG).
Illito-kaolinitic clay rich in hematite pure energy jeans from south Tunisia was investigated in view of producing geopolymer materials.Geopolymers with two different densities were elaborated: cement and foam.The effects of activator concentrations on compressive strength, water absorption (durability), open porosity, and bulk density of geopolyme
