MALTE INNOVATIVE PER LA COPERTURA DELLE CRESTE MURARIE IN AMBITO ARCHEOLOGICO
2014
The main objective of this study is to evaluate the opportunities offered by nanotechnologies to the production of innovative mortars with enhanced performances for the reconfiguration of walls ridges in the archaeological field. In particular, an already existing additive, based on silica nano-particles in aqueous solution, was tested mixing it in varying percentages to a hydraulic lime mortar and pozzolana. The following tests were carried out on different samples: resistance to bending and compression, adhesion to the surface, water absorption coefficient through capillarity, accelerated ageing test using salt mist. In the final stage, some comparative considerations among the different …
Asistētas reproduktīvas tehnoloģijas grūtniecība, tās iznākums mātēm un jaundzimušajiem
2019
Ievads. Pēc PVO datiem, neauglība skar katru 4 pāri reproduktīvā vecumā, līdz ar to asistētās reproduktīvās tehnoloģijas paliek arvien populārākas. Neskatoties uz mākslīgās apaugļošanas iespēju neauglīgam pārim tikt pie bērna, zinātniskajā literatūrā aprakstīta negatīva superovulācijas ietekme uz sievietes organismu, palielinot komplikāciju attistīšanās risku, kas varētu ietekmēt sievietes un jaundzimušā veselības stāvokli. Darba mērķis. Izpētīt grūtniecības un perinatālo komplikāciju iestāšanās biežumu, superovulācijas ietekmi uz grūtniecības iznākumu, kā arī salīdzināt jaundzimušā parametrus mākslīgās apaugļošanas un spontānas grūtniecības grupās. Materiāli un metodes. Prospektīvs, salīdz…
Towards explainable interactive multiobjective optimization : R-XIMO
2022
AbstractIn interactive multiobjective optimization methods, the preferences of a decision maker are incorporated in a solution process to find solutions of interest for problems with multiple conflicting objectives. Since multiple solutions exist for these problems with various trade-offs, preferences are crucial to identify the best solution(s). However, it is not necessarily clear to the decision maker how the preferences lead to particular solutions and, by introducing explanations to interactive multiobjective optimization methods, we promote a novel paradigm of explainable interactive multiobjective optimization. As a proof of concept, we introduce a new method, R-XIMO, which provides …
Desigualdades algorítmicas: conductas de alto riesgo para los derechos humanos
2022
Este artículo propone un análisis sobre las desigualdades originadas o reforzadas por el uso de los modelos y programas de aprendizaje automático que encuentran una de sus principales justificaciones en el principio de precisión predictiva, así como sobre algunas respuestas que cabe esperar del sistema jurídico para abordarlas. Este tema ha sido tratado fundamentalmente bien a través de la tutela del derecho a la privacidad y la protección de datos, bien mediante la elaboración de códigos éticos. Aquí se adoptarán dos perspectivas distintas a las anteriores. En primer lugar, el enfoque del riesgo, marco en el que se ha empla-zado recientemente la regulación europea de la inteligencia artifi…
Cognitive Mimetics for AI Ethics : Tacit Knowledge, Action Ontologies and Problem Restructuring
2020
Ethics and ethical information processing are an important problem for AI development. It is important for self-evident reasons, but also challenging in its’ implications and should be welcomed by designers and developers as an interesting technical challenge. This article explores AI ethics as a design problem and lays out how cognitive mimetics could be used a method for its design. AI ethics is conceptualized as a problem of implementation on the one hand, and as a problem of ethical contents on the other. From the viewpoint of human information processing, ethics becomes a special case of ethical information processing - one that has deep implications in terms of AI abilities and inform…
How Do Software Companies Deal with Artificial Intelligence Ethics? : A Gap Analysis
2022
The public and academic discussion on Artificial Intelligence (AI) ethics is accelerating and the general public is becoming more aware AI ethics issues such as data privacy in these systems. To guide ethical development of AI systems, governmental and institutional actors, as well as companies, have drafted various guidelines for ethical AI. Though these guidelines are becoming increasingly common, they have been criticized for a lack of impact on industrial practice. There seems to be a gap between research and practice in the area, though its exact nature remains unknown. In this paper, we present a gap analysis of the current state of the art by comparing practices of 39 companies that …
Towards a Great Design of Conceptual Modelling
2020
Humankind faces a most crucial mission; we must endeavour, on a global scale, to restore and improve our natural and social environments. This is a big challenge for global information systems development and for their modelling. In this paper, we discuss on different aspects of conceptual modelling in global environmental context. The paper is the summary of the panel session “The Future of Conceptual Modelling” in the 29th International Conference on Information Modelling and Knowledge Bases. peerReviewed
A New Feature Selection Methodology for K-mers Representation of DNA Sequences
2015
DNA sequence decomposition into k-mers and their frequency counting, defines a mapping of a sequence into a numerical space by a numerical feature vector of fixed length. This simple process allows to compare sequences in an alignment free way, using common similarities and distance functions on the numerical codomain of the mapping. The most common used decomposition uses all the substrings of a fixed length k making the codomain of exponential dimension. This obviously can affect the time complexity of the similarity computation, and in general of the machine learning algorithm used for the purpose of sequence analysis. Moreover, the presence of possible noisy features can also affect the…
Investigating the effectiveness of a digital game-based task on the acquisition of word knowledge
2020
This study investigates the probable effect of a digital game-based vocabulary learning (DGBVL) task on the acquisition of some components of a word knowledge framework. In so doing, 124 Persian speakers (56 males and 68 females) were randomly assigned to either a control or an experimental group. The experimental group participants completed a DGBVL task for acquiring ten low-frequent inanimate object names, or lexical nouns, by playing a commercial adventure game. The control group participants practiced the same words in a fill-in-the-blank vocabulary acquisition exercise. In brief, first, all participants sat for a word-checklist and a proficiency test; next, they completed their tasks,…
A Contrastive Evaluation of Word Sense Disambiguation Systems for Finnish
2019
Aiempi saneiden alamerkitysten yksiselitteistämistä käsittelevä työ, kuten monet muut luonnollisen kielen käsittelyyn liittyvät tehtävät, on enimmäkseen keskittynyt englannin kieleen. Vaikka hieman työtä on tehty myös muilla kielillä, mukaan lukien uralilaiset kielet, vertailevaa arviointia suomen kielen saneiden alamerkitysten yksiselitteistämisestä ei ole tähän mennessä julkaistu huolimatta siitä, että tarvittavat leksikaaliset resurssit, erityisesti FinnWordNet, ovat jo pitkään olleet saatavilla. Tämä työ pyrkii korjaamaan tilanteen. Se tarjoaa tuloksia merkittävimpiä lähestymistapoja saneiden alamerkitysten yksiselitteistämiseen edustavista ohjelmista, sisältäen joitakin parhaiten engla…
