It is described how any problem specified using CLP* can be converted into an implicit AND/OR graph, and presented an algorithm called GenSolve which can branch-and-bound using upper and lower bound estimates, thus exploiting the full pruning power of heuristic search techniques.
Integral Control of Stable Negative-Imaginary Systems Preceded by Hysteresis Nonlinearity
It is effectively shown that integral tracking controllers are guaranteed to exist when a stable NI system with sign-definite dc-gain is preceded by such hysteresis nonlinearities, and it is established that the integral controller gain can be any positive diagonal matrix.
Counter-ion Effect on Micellization of Ionic Surfactants: A Comprehensive Understanding with Two Representatives, Sodium Dodecyl Sulfate (SDS) and Dodecyltrimethylammonium Bromide (DTAB)
Various micelle parameters viz., critical micelle concentration (CMC), counter-ion binding (β), aggregation number (N), hydrodynamic radius (Rh), micelle zeta potential (ζ) and energetic parameters,…
Cobalt-Catalyzed sp(2) -C-H Activation: Intermolecular Heterocyclization with Allenes at Room Temperature.
A unified approach to synthesize a diverse array of biologically and pharmaceutically relevant heterocyclic moieties by cobalt-catalyzed directed C-H functionalization was envisioned and led to the regioselective formation of dihydroisoquinolin-1(2H)-ones, isoquinolin -ones, dihydropyridones, and pyridone.
