05 Sep 1994TL;DR: In this paper, the synchronous reluctance motor drive is illustrated as a new incoming technology solution and the obtainable performance in terms of torque per volume is compared to that of brushless and induction motors.
Abstract: The modern synchronous reluctance motor drive is illustrated as a new incoming technology solution. High anisotropy motor design is briefly summarized. The obtainable performance in terms of torque-per-volume is then compared to that of brushless and induction motors. With reference to traditional vector current control, the peculiarities of the synchronous reluctance motor drive are shown. Moreover, the effect of some second-order control aspects are evidenced, together with the possible advantages of adoption of flux-observer based schemes. Finally, both research and industrial trends in this field are summarized. >

TL;DR: In this article, an extended topological method has been proposed by incorporating several specific features of power systems such as electrical distance, power transfer distribution factors and line flow limits, starting from the extended metric for efficiency named as net-ability, an extended betweenness and proposes a joint method of extended and betweenness to rank the most critical lines and buses in an electrical power grid.
Abstract: Vulnerability analysis of power systems is a key issue in modern society and many efforts have contributed to the analysis. Complex network metrics for the assessment of the vulnerability of networked systems have been recently applied to power systems. Complex network theory may come in handy for vulnerability analysis of power systems due to a close link between the topological structure and physical properties of power systems. However, a pure topological approach fails to capture the engineering features of power systems. So an extended topological method has been proposed by incorporating several of specific features of power systems such as electrical distance, power transfer distribution factors and line flow limits. This paper defines, starting from the extended metric for efficiency named as net-ability, an extended betweenness and proposes a joint method of extended betweenness and net-ability to rank the most critical lines and buses in an electrical power grid. The method is illustrated in the IEEE-118-bus, IEEE-300-bus test systems as well as the Italian power grid.

TL;DR: In this paper, the authors investigated the Moyal-Weyl deformations of superspace and their compatibility with supersymmetry and gave the supersymmetric version of the Born-Infeld action with a B-field turned on, which is believed to be related to the non commutative U(1) gauge theory.
Abstract: We investigate some aspects of Moyal-Weyl deformations of superspace and their compatibility with supersymmetry. For the simplest case, when only bosonic coordinates are deformed, we consider a four dimensional supersymmetric field theory which is the deformation of the Wess-Zumino renormalizable theory of a chiral superfield. We then consider the deformation of a free theory of an abelian vector multiplet, which is a non commutative version of the rank one Yang-Mills theory. We finally give the supersymmetric version of the $\alpha'\mapsto 0$ limit of the Born-Infeld action with a B-field turned on, which is believed to be related to the non commutative U(1) gauge theory.

TL;DR: It is shown here that all three dimensions are important for overall prediction success and that it is possible to improve significantly along the second dimension by going beyond the pair-wise Potts models from statistical physics, which have hitherto been the focus of the field.
Abstract: Correlation patterns in multiple sequence alignments of homologous proteins can be exploited to infer information on the three-dimensional structure of their members. The typical pipeline to address this task, which we in this paper refer to as the three dimensions of contact prediction, is to (i) filter and align the raw sequence data representing the evolutionarily related proteins; (ii) choose a predictive model to describe a sequence alignment; (iii) infer the model parameters and interpret them in terms of structural properties, such as an accurate contact map. We show here that all three dimensions are important for overall prediction success. In particular, we show that it is possible to improve significantly along the second dimension by going beyond the pair-wise Potts models from statistical physics, which have hitherto been the focus of the field. These (simple) extensions are motivated by multiple sequence alignments often containing long stretches of gaps which, as a data feature, would be rather untypical for independent samples drawn from a Potts model. Using a large test set of proteins we show that the combined improvements along the three dimensions are as large as any reported to date.

TL;DR: The state of the art of the aluminum alloys used in the laser powder bed fusion process, together with the microstructural and mechanical characterizations are reviewed.
Abstract: Aluminum alloys are key materials in additive manufacturing (AM) technologies thanks to their low density that, coupled with the possibility to create complex geometries of these innovative processes, can be exploited for several applications in aerospace and automotive fields. The AM process of these alloys had to face many challenges because, due to their low laser absorption, high thermal conductivity and reduced powder flowability, they are characterized by poor processability. Nowadays mainly Al-Si alloys are processed, however, in recent years many efforts have been carried out in developing new compositions specifically designed for laser based powder bed AM processes. This paper reviews the state of the art of the aluminum alloys used in the laser powder bed fusion process, together with the microstructural and mechanical characterizations.
