Publisher Copyright: © 2021 IEEE. Standard mathematical-programming-based models have attracted considerable attention for optimizing distribution system planning and operation due to their salient advantages. More specifically, mixed-integer linear programming (MILP) has proven very effective in modeling such problems. The availability of optimization software for efficiently solving MILP problems with guaranteed convergence to optimality while providing a measure of the distance to the optimal solution has made MILP models more popular. Although a plethora of efficient MILP formulations have been proposed for planning and operating studies of distribution grids, incorporating reliability into such models is still challenging. Recently, several innovative techniques have been proposed in the literature for optimization-based reliability evaluation of distribution networks. However, either oversimplifications or high computation costs are featured, thereby limiting the applicability of such approaches in practical problems. To overcome this issue, this paper presents an enhanced MILP model for distribution system reliability evaluation. The proposed model boosts the computational effectiveness without sacrificing solution accuracy. Numerical experience with the proposed model demonstrates its superior performance over the state of the art.

This text makes a reflection and seeks to put into practice the concept off-centre. Off-centred or off centering is formulated as an epistemological/ethical/political/affective concept; a problematic concept, giving rise, which seeks to locate poietic enunciation places, not to tribute privileged forms of power or subordination to an heteronomous logic of colonization. It’s applied to the analysis of some choreographic works formulated as reflections on the imaginary inscription of mexican historical stories and as a critical enquiries about masculine patriarchal affective subjetivation. El texto reflexiona, y busca poner en práctica, el concepto de descentramiento. Se le formula como un esfuerzo epistemológico/ético/político/afectivo en devenir problemático, que busca ubicar lugares de enunciación poiética que no tributen ninguna forma de privilegio de poder o de supeditación a una lógica heterónoma colonizante. Se le aplica en el análisis de algunas obras coreográficas que se formularon como reflexiones sobre la inscripción imaginaria en relatos históricos mexicanos y como indagaciones críticas de la subjetivación afectiva masculina patriarcal.

El presente dossier constituye el segundo número consecutivo de la Revista Artes da Cena, que reúne textos dedicados a la idea de descentramiento en el campo de la investigación en danza. Forma parte de las acciones que de la Red Descentradxs - Descentrar la investigación en danza, junto a más de 30 investigadorxs y artistxs provenientes de América Latina y Europa. En este segundo número presentamos tres ejes de discusión: Manifiestos descentrados - Historias situadas - Dramaturgias. El primero reúne artículos que abordan la descentralización en relación al tema del canon y la identidad, en diálogo con conceptos provenientes de los estudios de danza, la performance, el pensamiento decolonial, la filosofía política, la fenomenología y los estudios de género, y las problemáticas de la representatividad y el racismo. En el segundo eje, se agrupan textos vinculados con las historias de la danza en Cuba, Brasil y Chile que abordan la historia desde una perspectiva epistemológica crítica, planteando microrrelatos desestabilizadores de discursos hegemónicos. Las discusiones vinculadas a la dramaturgia de y desde el movimiento que busca, a partir de estudios de caso, abordar temas sobre el cuerpo, la democracia cultural, la cultura afrobrasileña, conforman el tercer eje.

Pesquisas ligadas às dramaturgias do movimento, com base em estudos de caso, leituras sobre o corpo, democracia cultural e culturas afro-brasileiras, constituem o terceiro eixo. &nbsp

International audience; It is impossible to dissociate the evolution of Enric Miralles' architecture from the development of his own system of representation. Founded on an initial position inherited from his training at the Barcelona School of Architecture and his practice at the office of Viaplana-Piñón, where he acquired a liking for precision in drawing and a graphic style based exclusively on lines of the same thickness, Miralles soon developed a method defined by a customised use of orthographic projections, connected to a fragmented conception of the architectural plan and space itself. The Miralles Projection explains both the origin and evolution of Miralles’ system of representation, from his time as an architecture student and collaborator at Viaplana-Piñón to the latest projects he designed with Benedetta Tagliabue, including the important period with Carme Pinós. With a curated selection of previously unpublished drawings, it demonstrates on a fundamental level how the evolution of his architecture ran parallel to that of representation, thus illustrating their indissolubility and mutual interdependence.

This article discloses a domestic system that allows greater energy efficiency in a home located in Mexico City, which facilitates its contribution to a green urbanism by installing it in the buildings of the City.The system was designed and built using a solar heater (CalGen) that was installed in a house with four people. Aluminum cans were used in the CalGen as vacuum tubes, the water heated in the cans was used in the shower, in addition the CalGen structure were placed photoelectric cells, which were controlled by an Arduino Uno, in order to increase the efficiency of the solar radiation. The water heated by the CalGen helps to reduce the emissions 3.6 kiolograms (kg) of carbon dioxide (CO2) per day, since before installing the system the house used principally liquefied petroleum gas (LPG) to heat the water. The water circulating inside the aluminum cans is heated by solar radiation, leaving the water at an average temperature of 37.71°C. The eight photoelectric cells generate 240 watts per day (W/day). The electricity generated by the photoelectric cells is stored in rechargeable batteries. The methodology of the tests and construction of CalGen is shown, as well as the changes that were made from the tests. There is also a cost-benefit study that CalGen had in housing.It should promote the design of cities where the environment of the quality of life of human beings is healthier and more sustainable, given that the space of cities is being increasingly demanded. Green buildings should not be an optional trend, but a fundamental requirement, taking advantage of and adapting existing spaces more effectively.
