We develop the theory of smooth principal bundles for a group G, using framework diffeological spaces. After giving new examples showing why arbitrary cannot be classified, we define D-numerable bundles, analogs numerable from topology, and prove that pulling back bundle along smoothly homotopic maps gives isomorphic pullbacks. then structures on Milnor’s spaces EG BG, show → BG is bundle, it c...
in practice, obtaining the global optimum for the economic dispatch {bf (ed)}problem with ramp rate limits and prohibited operating zones is presents difficulties. this paper presents a new andefficient method for solving the economic dispatch problem with non-smooth cost functions using afuzzy adaptive genetic algorithm (faga). the proposed algorithm deals with the issue ofcontrolling the ex...
the seed of croton tiglium l. (sct) is a well known folk medicine. in china, it has used to treat gastrointestinal disorders, intestinal inflammation, rheumatism, and so on. previous studies established its purgative and inflammation properties. in addition, the effects of essential oil of sct on intestinal transit and gastrointestinal tract has been studied. in the present study, we evaluated ...
in this paper, under the existence of system uncertainties, external disturbances, and input nonlinearity, global finite time synchronization between two identical attractors which belong to a class of second-order chaotic nonlinear gyros are achieved by considering a method of continuous smooth second-order sliding mode control (hoamsc). it is proved that the proposed controller is robust to m...
abstract this paper attempts to re-investigate the catching-up (stochastic convergence) hypothesis among the selected 16 oecd countries applying the time series approach of convergence hypothesis with annual data over one century. to reach this aim, we propose a model which specifies a trend function, incorporating both types of structural breaks – that is, sharp breaks and smooth shifts using ...
conclusions these results showed an inhibitory effect for the extract of asafetida on muscarinic receptors of tracheal smooth muscle. results the ec50 obtained in the presence of higher concentration of the extract muscle was significantly higher compared to saline (p < 0.01). the maximum responses to methacholine in the presence of higher concentration of the extract (10 mg/ml) was significant...
