Do You Hear What I See? Analyzing Visibility and Audibility in the Rock Art Landscape of the Alicante Mountains of Spain

This article examines the relationship between rock art landscapes and perception. It pays particular attention to vision and hearing, the two key senses for landscape awareness. Given the importance of scale in the study of rock art landscapes, a distinction is made between the adjacent landscape and the broader territorial scale. Several methodological improvements are suggested, including the importance of clipping viewsheds in GIS analysis and measuring directionality instead of orientation of the rock art shelters. In our case-study we explore the rock art landscape of the AlicanteMountains (northeastern Spain) during the Neolithic period (ca. 5600 to 2800 cal bc). A new interpretation of how the cognitive and symbolic behavior of communities changed over time is offered. We argue that the analysis of perception in rock art landscapes can provide novel ways of understanding communities' distinctive appropriation of their landscapes, linking both the tangible and intangible aspects of their culture

On the development of a MODEM for data transmission and control of electrical household appliances using the low-voltage power-line

This paper presents a CMOS 0,6μm mixed-signal MODEM ASIC for data transmission on the low-voltage power line. The circuit includes all the analog circuitry needed for input interfacing and modulation/demodulation (PLL-based frequency synthesis, slave filter banks with PLL master VCO for tuning, decision circuitry, etc.) plus the logic circuitry needed for control purposes. The circuit operates correctly in the whole industrial temperature range, from -45 to 80°C, under 5% variations of the 3.3V supply voltage.Comisión Interministerial de Ciencia y Tecnología FD97-1611(TIC)Ministerio de Ciencia y Tecnología TIC200 1-092

SIRENA: A CAD environment for behavioural modelling and simulation of VLSI cellular neural network chips

This paper presents SIRENA, a CAD environment for the simulation and modelling of mixed-signal VLSI parallel processing chips based on cellular neural networks. SIRENA includes capabilities for: (a) the description of nominal and non-ideal operation of CNN analogue circuitry at the behavioural level; (b) performing realistic simulations of the transient evolution of physical CNNs including deviations due to second-order effects of the hardware; and, (c) evaluating sensitivity figures, and realize noise and Monte Carlo simulations in the time domain. These capabilities portray SIRENA as better suited for CNN chip development than algorithmic simulation packages (such as OpenSimulator, Sesame) or conventional neural networks simulators (RCS, GENESIS, SFINX), which are not oriented to the evaluation of hardware non-idealities. As compared to conventional electrical simulators (such as HSPICE or ELDO-FAS), SIRENA provides easier modelling of the hardware parasitics, a significant reduction in computation time, and similar accuracy levels. Consequently, iteration during the design procedure becomes possible, supporting decision making regarding design strategies and dimensioning. SIRENA has been developed using object-oriented programming techniques in C, and currently runs under the UNIX operating system and X-Windows framework. It employs a dedicated high-level hardware description language: DECEL, fitted to the description of non-idealities arising in CNN hardware. This language has been developed aiming generality, in the sense of making no restrictions on the network models that can be implemented. SIRENA is highly modular and composed of independent tools. This simplifies future expansions and improvements.Comisión Interministerial de Ciencia y Tecnología TIC96-1392-C02-0

Primera campaña de prospecciones arqueológicas en la comarca de Tarazona y el Moncayo. Avance preliminar de los resultados de la campaña de 2010

La falta de un estudio arqueológico integral de la Comarca de Tarazona y el Moncayo, junto con la ausencia de una carta arqueológica comarcal de la zona, motivó el inicio de estas prospecciones arqueológicas con el objetivo de perdurar en el tiempo hasta completar totalmente la información arqueológica de esta comarca. En su primera campaña se han centrado en el paraje denominado Cañada Madre que comprende parte de los términos municipales de Tarazona, El Buste y Vera de Moncayo, obteniendo la identificación de yacimientos arqueológicos que abarcan desde el Paleolítico Medio hasta el siglo XX

Assessed by Machines: Development of a TAM-Based Tool to Measure AI-based Assessment Acceptance Among Students

In recent years, the use of more and more technology in education has been a trend. The shift of traditional learning procedures into more online and tech-ish approaches has contributed to a context that can favor integrating Artificial-Intelligence-based or algorithm-based assessment of learning. Even more, with the current acceleration because of the COVID-19 pandemic, more and more learning processes are becoming online and are incorporating technologies related to automatize assessment or help instructors in the process. While we are in an initial stage of that integration, it is the moment to reflect on the students' perceptions of being assessed by a non-conscious software entity like a machine learning model or any other artificial intelligence application. As a result of the paper, we present a TAM-based model and a ready-to-use instrument based on five aspects concerning understanding technology adoption like the AI-based assessment on education. These aspects are perceived usefulness, perceived ease of use, attitude towards use, behavioral intention, and actual use. The paper's outcomes can be relevant to the research community since there is a lack of this kind of proposal in the literature

Un caso de Arqueología Experimental aplicado a la Arqueología Musical

Evaluamos en este estudio las posibilidades organológicas y el rendimiento musical del aerófono gravetiense más completo recuperado en el yacimiento de Isturitz, a partir de dos réplicas del original realizadas en ulnas de buitre leonado (Gyps fulvus). Estas réplicas, obtenidas mediante una cadena operativa de acciones muy simples, nos permiten dar cuenta de su rendimiento acústico según tres formas de producir su sonido. También se han anali- zado las alteraciones laborales producidas en los útiles líticos utilizados y en la superficie trabajada de los huesos

El establecimiento de la filiación en las técnicas de reproducción humana asistida

La cuestión que se ha tratado en este Trabajo de Fin de Grado es la relativa a cómo podemos determinar la filiación de los padres y de las madres respecto de los hijos nacidos a través de las técnicas de reproducción humana asistidas. Con este trabajo de fin de grado lo que se pretende es dar respuesta a las dudas, preguntas o enigmas de cómo un hombre y/o una mujer puede acceder a las técnicas de reproducción humana asistida y que además el bebé resultante pueda ser reconocido legalmente como su hijo o hija con las consecuencias que se derivan de ello

How to Measure Teachers' Acceptance of AI-driven Assessment in eLearning

The use of AI is becoming a growing reality the educational field. One of the activities in which it is beginning to be implemented is the assessment of student achievement. This way, we can find in the literature an increasing number of investigations focused on the possibilities offered by the adoption of AI-driven assessment. However, the use of AI is also a source of concern that raises suspicions in some sectors of our society. In this context, knowing the position of the teachers towards this topic is critical to guarantee the successful development of the field. This paper intends to fill a research gap in the literature by offering a technology adoption model based on TAM to study the factors that condition the use of AI-driven assessment among teachers. To present this model we offer a background on the use of AI in education and the technology acceptance among teachers, as well as the definition of the eight constructs and the relational hypotheses included. Finally, the possibilities of the model and future lines of research are discussed
