Testo completoIn 2005, cosmetic market growth stop. Using this way, this doctoral work explores innovation methods in busy market. Very often, knowledges and sciences are crossing to emerge innovation. Chaos theory and psychoanalysis have been used to complete marketing. Micro innovation is the thesis foundation. Micro innovation alters lightly global supply. But it disrupts the sensorial point of view of consumer, one of key to win new products launch. It proves that marketing theory can be renewed by new tools (analysis and chaos theory). Micro innovation is showing a schema of peoples who can consume old brand. This paper tries to prove to marketers and managers that micro innovation can be used in beauty and cosmetic markets

Testo completoThis manuscript provides novel sufficient conditions for the synthesis of stabilizing dynamic output-feedback controllers with anti-windup compensation for linear systems subject to input saturation. Given a dynamic output-feedback controller, stabilizing the linear closed-loop, the design of a static anti-windup loop is also addressed. Based on Linear and Bilinear Matrix Inequalities (LMIs and BMIs, respectively), together with appropriate transformations and sector conditions, the results exposed exploit the sign-indefinite quadratic forms involving the closed-loop state and the deadzone of the control input to define piecewise smooth Lyapunov functions. The proposed solutions leverage additional degrees of freedom with respect to the classical quadratic stabilization approach to construct global or regional exponential stability certificates of the origin of the closed-loop system.The obtained LMIs are used as constraints in convex optimization schemes and may be easily solved with commercial solvers and optimizers. For the conditions formulated in terms of BMIs, iterative algorithms based on a convex-concave decomposition are given to solve such bilinear conditions. To be executed, such algorithms require feasible initial conditions that we provide by exploiting the structure of the BMIs. With guaranteed global or regional exponential stability, the solutions exposed in this manuscript also ensure a prescribed local exponential convergence rate. Additionally, when only regional exponential stability is attainable, the proposed regional designs allow determining inner-approximations of the basin of attraction of the origin for the closed-loop system, with maximized volume. Numerical applications are presented in this manuscript to illustrate the effectiveness and drawbacks of each one of the proposed methods

Testo completoThis Thesis is concerned with a study of the "Gif system", a means of oxidising saturated hydrocarbons, using a reductant, zinc, a trinuclear iron complex, Fe3 O(CH3C00)6 (Pyr)3,5 and molecular oxygen in a pyridine-acetic acid mixture, in air and at ambient temperature. It differs from other systems in its greater oxidation yields and above all by its interesting and unusual selectivity for the preferential activation of secondary C-H bonds. An in-depth study of the role of pyridine in this system has given us a better understanding of the necessity of this solvent for the efficiency and selectivity of the Gif system. It apparently functions essentially as a ligand for iron and as an electron transfer reagent. By introducing many different metal salts into the Gif system, in the presence and absence of Fe3 O(CH3C00)6 (Pyr)3,5 ,we have been able to establish the undoubted specific requirement for iron salts. Further studies have been performed with tungsten and cerium salts. Finally, a series of experiments was carried out with several organic compounds, able to react with the metallocarbene which is postulated to account for ketone formation. Of these, diphenyldiselenide proved the most interesting. Through this study we have discovered a new reaction of obvious synthetic interest, the facile conversion, in satisfactory yields, under mild conditions, of a hydrocarbon into its phenylselenide derivative

Testo completoThis thesis is concerned with a study of the "Gif system", a means of oxidising saturated hydrocarbons, using a reductant, zinc or iron, an iron catalyst and molecular oxygen in a pyridine-acetic acid mixture at room temperature. This system differs from other systems in its greater oxidation yield and, above all, by its interesting and unusual selectivity for the preferential activation of secondary C-H bonds: saturated hydrocarbons are oxidised mainly into ketones. We have examined the oxidation of complex natural substrates, steroids and terpenoids. The oxidation of cholesterol derivatives results mainly in side-chain cleavage to yield the corresponding 20-ketone. A study of the effect of temperature has enabled us to show that the mechanism of this transformation involves a 25-alkoxy radical as key-intermediate. The oxidation of several terpenoids has yielded in one step a large number of new ketones and has revealed the special reactivity of the Gif system towards carbon-carbon double bonds. Finally, the introduction of adequate reagents into the original system has lead us to the discovery of a variety of derived reactions. Thus, the Gif system allows to carry out the direct transformation of a saturated hydrocarbon into phenyl-seleno-, phenyl-thio, chloro- or brome derivatives, depending on the reaction conditions
