Abstract

In the investigated area the overall abundance of krill was small and was increasing with the distance from ice. However, with the data available, it was not possible to decide whether this increase was related to the ice border or was a part of a larger scale phenomenon. The depth distributions as well as the mean values of krill depth were similar to those of open water both in this study and reported in literature.

Abstract

Department of Electrical Engineering, Anna University Regional Centre, Coimbatore, India This paper presents a new approach to solve economic load dispatch (ELD) problem in thermal units with non-convex cost functions using differential evolution technique (DE). In practical ELD problem, the fuel cost function is highly non linear due to inclusion of real time constraints such as valve point loading, prohibited operating zones and network transmission losses. This makes the traditional methods fail in finding the optimum solution. The DE algorithm is an evolutionary algorithm with less stochastic approach to problem solving than classical evolutionary algorithms.DE have the potential of simple in structure, fast convergence property and quality of solution. This paper presents a combination of DE and variable neighborhood search (VNS) to improve the quality of solution and convergence speed. Differential evolution (DE) is first introduced to find the locality of the solution, and then VNS is applied to tune the solution. To validate the DE-VNS method, it is applied to four test systems with non-smooth cost functions. The effectiveness of the DE-VNS over other techniques is shown in general.

Abstract

Apologia filosofico-storica in cui si mostra il sesso delle donne superiore a quello degli uomini, published in 1737 by the Palermitan nobleman Vincenzo Di Blasi, is a collection of examples – taken from myth, history and literature – of feminine values and virtues, composed in support of the superiority of the “womanish sex” over the virile one. The work is closely linked to the Sicilian cultural context of that time, suspended between a fossilized scholastic philosophy and a slow reception of the secular and modern Cartesian thought. But it confirms – also in Sicily – the growing cultural and disseminating function acquired by the so called “art of conversation”, alongside the already institutionalized model proposed by the academies.
