Using the ARP-03 for high-resolution mapping of calcic horizons

2013

A b s t r a c t. The aim of this work is to present a fast and cheap method for high-resolution mapping of calcic horizons in vineyards based on geoelectrical proximal sensing. The study area, 45 ha located in southern Sicily (Italy), was characterized by an old, partially dismantled marine terrace and soils with a calcic horizon at different depths. The geoelectrical investigation consisted of a survey of the soil electrical resistivity recorded with the Automatic Resistivity Profiling-03 sensor. The electrical resistivity values at three pseudo-depths, 0-50, 0-100 and 0-170 cm, were spatialized by means of ordinary kriging. A principal component analysis of the three electrical resistivit…

The Virtual Reconstruction of the Aesculapius and Hygeia Statues from the Sanctuary of Isis in Lilybaeum: Methods and Tools for Ancient Sculptures’ E…

2022

Thanks to recent technological developments in 3D surveys, computer graphics and virtual reality, new scenarios have been opened for the documentation and enhancement of ancient sculptures. When not totally preserved, sculptures can be digitally reproduced, modified and visualized to simulate their physical or virtual reconstruction in a non-invasive way for specialists or for dissemination aims. The virtual sculptural reconstruction process starts usually from the 3D survey of real fragments, and then continues by integrating missing parts with 3D modelling techniques by means of source evaluation. Along with primary data sources (reality-based model), secondary data sources (photos, drawi…

Revealing the pace of river landscape evolution during the Quaternary: recent developments in numerical dating methods

2016

During the last twenty years, several technical developments have considerably intensified the use of numerical dating methods for the Quaternary. The study of fluvial archives has greatly benefited from these enhancements, opening new dating horizons for a range of archives at distinct time scales and thereby providing new insights into previously unanswered questions. In this contribution, we separately present the state of the art of five numerical dating methods that are frequently used in the fluvial context: radiocarbon, Luminescence, Electron Spin Resonance (ESR), 230Th/U and terrestrial cosmogenic nuclides (TCN) dating. We focus on the major recent developments for each technique th…

Continuous experimentation on artificial intelligence software : a research agenda

2020

Moving from experiments to industrial level AI software development requires a shift from understanding AI/ ML model attributes as a standalone experiment to know-how integrating and operating AI models in a large-scale software system. It is a growing demand for adopting state-of-the-art software engineering paradigms into AI development, so that the development efforts can be aligned with business strategies in a lean and fast-paced manner. We describe AI development as an “unknown unknown” problem where both business needs and AI models evolve over time. We describe a holistic view of an iterative, continuous approach to develop industrial AI software basing on business goals, requiremen…

Hardware implementation of content based video indexing algorithms

2005

This paper focus on hardware implementation of content based video indexing techniques by using the FPGA technology. We aim to propose hardware modules that can satisfy requirements of constrained applications, such as real time applications and complex applications that can combine a large number of techniques in the same indexing system. We represent tow examples of micro-architectures related to the dominant colors descriptor and the compact color descriptor.

Lost People : How National AI-Strategies Paying Attention to Users

2021

Abstract. This paper focuses on how major national strategies call attention to the human dimensions of artificial intelligence (AI). All intelligent technologies using AI are constructed for people as either active users or as relatively passive target persons. Thus, human properties and human research should have an important role in developing future AI systems. In these development strategies, it is interesting to pay attention to the underlying intuitive assumptions and tacit commitments. This issue is especially interesting when we think about what governmental working groups say about people and their changing lives in their strategies. The traditional stances adopted in writing nati…

Accelerating bioinformatics applications via emerging parallel computing systems [Guest editorial]

2015

The papers in this issue focus on advanced parallel computing systems for bioinformatics applications. This papers provide a forum to publish recent advances in the improvement of handling bioinformatics problems on emerging parallel computing systems. These systems can be characterized by exploiting different types of parallelism, including fine-grained versus coarse-grained and thread-level parallelism versus datalevel parallelism versus request-level parallelism. Hence, parallel computing systems based on multi- and many-core CPUs, many-core GPUs, vector processors, or FPGAs offer the promise to massively accelerate many bioinformatics algorithms and applications, ranging from computeint…

Plastic end-of-life alternatives, with a focus on the agricultural sector

2021

The end of life (EoL) of plastic polymers depends on when they stop being considered a resource and begin to be considered a waste. Even with dynamic management, plastic pollution will increase in the coming decades. Reduction strategies focus on reducing the quantities of materials used in the construction of individual objects for packaging, support for reuse and recycling, incentives for gathering low-value plastics, awareness, and simplification. The agricultural sector, a sector in which the use of plastic is (apparently) not high, needs to combine environmental, social, and above all economic aspects, which can help entrepreneurs in the sector to optimize the recycling process.

Possibilitats i riscs de les fonts orals en la investigació historicoeducativa

2006

-M.Carmen.Agullo@uv.es Les fonts orals se’ns presenten com una metodologia particularment adequada per donar la paraula a grups socials tradicionalment exclosos de la història oficial. Les seues tècniques, entre les quals destacaríem el mètode biogràfic, les històries de vida i els relats de la vida escolar, es poden utilitzar en el doble vessant de la investigació historicoeducativa i com a instrument de treball dins de l’aula. La seua principal aportació, la possibilitat de reconstruir la memòria escolar recuperant els fets amb el valor afegit de la subjectivitat de les persones que els relaten, és el seu risc més important, que es pot contrarestar mitjançant la rigorosa aplicació dels cr…
