Impacts and adaptive capacity as drivers for prioritizing agricultural adaptation to climate change in Europe

In the face of likely climate change impacts policy makers at different spatial scales need access to assessment tools that enable informed policy instruments to be designed. Recent scientific advances have facilitated the development of improved climate projections, but it remains to be seen whether these are translated into effective adaptation strategies. This paper uses existing databases on climate impacts on European agriculture and combines them with an assessment of adaptive capacity to develop an interdisciplinary approach for prioritising policies. It proposes a method for identifying relevant policies for different EU countries that are representative of various agroclimatic zones. Our analysis presents a framework for integrating current knowledge of future climate impacts with an understanding of the underlying socio-economic, agricultural and environmental traits that determine a region’s capacity for adapting to climate change.

A self-adaptive image processing application based on evolvable and scalable hardware

Evolvable Hardware (EH) is a technique that consists of using reconfigurable hardware devices whose configuration is controlled by an Evolutionary Algorithm (EA). Our system consists of a fully-FPGA implemented scalable EH platform, where the Reconfigurable processing Core (RC) can adaptively increase or decrease in size. Figure 1 shows the architecture of the proposed System-on-Programmable-Chip (SoPC), consisting of a MicroBlaze processor responsible of controlling the whole system operation, a Reconfiguration Engine (RE), and a Reconfigurable processing Core which is able to change its size in both height and width. This system is used to implement image filters, which are generated autonomously thanks to the evolutionary process. The system is complemented with a camera that enables the usage of the platform for real time applications.

Real-Time Adaptive Multi-Classifier Multi-Resolution Visual Tracking Framework for Unmanned Aerial Vehicles

This paper presents a novel robust visual tracking framework, based on discriminative method, for Unmanned Aerial Vehicles (UAVs) to track an arbitrary 2D/3D target at real-time frame rates, that is called the Adaptive Multi-Classifier Multi-Resolution (AMCMR) framework. In this framework, adaptive Multiple Classifiers (MC) are updated in the (k-1)th frame-based Multiple Resolutions (MR) structure with compressed positive and negative samples, and then applied them in the kth frame-based Multiple Resolutions (MR) structure to detect the current target. The sample importance has been integrated into this framework to improve the tracking stability and accuracy. The performance of this framework was evaluated with the Ground Truth (GT) in different types of public image databases and real flight-based aerial image datasets firstly, then the framework has been applied in the UAV to inspect the Offshore Floating Platform (OFP). The evaluation and application results show that this framework is more robust, efficient and accurate against the existing state-of-art trackers, overcoming the problems generated by the challenging situations such as obvious appearance change, variant illumination, partial/full target occlusion, blur motion, rapid pose variation and onboard mechanical vibration, among others. To our best knowledge, this is the first work to present this framework for solving the online learning and tracking freewill 2D/3D target problems, and applied it in the UAVs.

Objetos tenaces : adaptive reuse en Meatpacking, 1970–1985

OBJETOS TENACES versa sobre la práctica del adaptive reuse (la “reutilización adaptativa”, la reconversión) explicado a través del fenómeno de ruptura, suspensión y reconfiguración de vínculos que el objeto arquitectónico tiene con respecto a su medio económico, sociocultural, normativo y de utilitas. Se trata de un fenómeno en tres fases, muy próximo al mecanismo empleado por el readymade y por el display, que en arquitectura parte de la crisis que supone un cambio de circunstancias, un desarraigo del objeto respecto de su ámbito anterior. El mecanismo tiene vocación de intervención mínima, desde un posicionamiento actual que comprende el mundo construido como una realidad “ya hecha”, y donde las operaciones de proyecto son acciones de transformación que llevan de una situación de obsolescencia a otra de vigencia renovada, es decir, de una realidad completa a otra igualmente completa. Para ello, la investigación se sirve de tres ejemplos de un mismo entorno geográfico (el área en torno a Meatpacking, en el lado oeste del bajo Manhattan, Nueva York) y temporal (las últimas décadas del siglo XX, en las que los casos se solapan a pesar de tener desarrollos cronológicos diversos). Bell Telephone Laboratories, The West Side Improvement y The National Biscuit Company, reconvertidos a Westbeth, a The High Line y a Chelsea Market, construyen juntos el argumento por suma de conceptos, por adición de fenómenos, estudiando las cualidades y las circunstancias que hacen posible la continuidad de las estructuras, es decir, su supervivencia. El texto forma un corpus que proporciona algunas de las claves del objeto denominado como tenaz a través del análisis sincrónico del antes y el después de su puesta en crisis. A tal efecto, se exponen una serie de figuras razonadas entre las cuales figuran el lijado del barniz, los hilos compartidos, la máscara, la momificación y la vitrina, el puente sobre le desfiladero, el enfriamiento, o las reliquias, incrustaciones y adherencias, todas ellas encaminadas a explicar el proceso de renovación del artefacto como un cambio en el sentido, en el significado, y no tanto en lo material. Entre las consideraciones de la tesis está, por un lado, el carácter relativo del término tenacidad, concepto que define a los objetos que se encuentran y se reconocen en su idoneidad, que tienen capacidad de adaptación, y que precisan finalmente de grandes dosis de pragmatismo para su reconfiguración, siendo todas éstas condiciones necesarias pero sólo suficientes a posteriori. Por otro lado, el texto reflexiona acerca del intangible que comparten todos los objetos así llamados y que consiste en la condición, quizá formidable, de ser reconocibles por parte de los sucesivos intervinientes de su historia, convencidos de que su renovación supone una oportunidad; su desaparición, una pérdida. Finalmente, la investigación apunta hacia el concepto de anacronismo como justificación para los objetos que se demuestran adaptables a épocas sucesivas, y que encajan en el tiempo de forma compleja. ABSTRACT TENACIOUS OBJECTS deals with the practice of the adaptive reuse explained by means of the phenomenon of rupture, suspension and reconfiguration of links that the architectural object has vis-à-vis its economic, socio-cultural and regulatory environment, and its utilitas. It is a phenomenon structured in three stages, very close to the mechanism used by the readymade and by the display, which in architecture arise from the crisis that leads to a change in circumstances, an alienation of the object regarding its previous environment. The mechanism aims to the minimum intervention, from a current positioning which understands the world built as a reality “already made”, and where the operations of the project are transformative actions that take us from a situation of obsolescence to a situation of renewed validity, that is, from a complete reality to one just as complete. For this purpose, the research makes use of three examples in the same geographical area (the Meatpacking Discrict, in the Lower West Side of Manhattan, New York) and the same period (the last decades of the 20th century, in which the cases overlap in spite of their diverse chronological developments). Bell Telephone Laboratories, The West Side Improvement and The National Biscuit Company, reconverted into Westbeth, The High Line and Chelsea Market, make up, together, the argument as a sum of concepts, and addition of phenomena, studying the qualities and circumstances which make the continuity of the structures possible, that is, their survival. The text forms a corpus that provides some of the keys of the so-called tenacious object by means of the synchronic analysis of before and after its crisis. To this end, a series of reasoned figures is presented, including the sanding of varnish, the shared threads, the mask, the mummification and the display cabinet, the bridge over the gorge, cooling, or the relics, incrustations and adherences, all of them aimed at explaining the renovation process of the artifact as a change in the sense and the meaning, rather than the material. The considerations of this dissertation include, on the one hand, the relative nature of the term tenacity, a concept which defines the objects found and recognized in their suitability, that are capable of adapting and which finally require large doses of pragmatism for their reconfiguration, all these conditions being necessary but only sufficient a posteriori. On the other hand, the text reflects on the intangible shared among all the so-called objects, and which consists of the condition, perhaps extraordinary, of being recognized by the subsequent interveners of their history, convinced that their renovation represents an opportunity; their disappearance, a loss. Finally, the dissertation studies the concept of anachronism as a justification for the objects that prove to adapt to subsequent periods, and which fit in time in a complex manner.
