Fruit and Vegetable Derived Waste as a Sustainable Alternative Source of Nutraceutical Compounds
2018
Dietary phytochemicals are widely investigated in the eld of chemistry, biology, nutrition, and medicine for their potential health-promoting eects. Indeed, many in vitro and in vivo studies provide evidence that a number of these compounds are involved in the prevention and/or control of chronic disorders such as cancer and cardiovascular diseases. e exponential growth of plant waste production from the agrofood industry is a critical global issue, considering its storage, disposal, environmental impact, and potential health risks. However, the exploitation of plant wastes/by-products for the recovery of added-value compounds oers new avenue for industrial growth and waste management. I…
Automated and Online Eye Blink Artifact Removal from Electroencephalogram
2019
Eyeblink artifacts often contaminates electroencephalogram (EEG) signals, which could potentially confound EEG's interpretation. A lot offline methods are available to remove this artifact, but an online solution is required to remove eyeblink artifacts in near real time for EEG signal to be beneficial in applications such as brain computer interface, (BCI). In this work, approaches that combines unsupervised eyeblink artifact detection with Empirical Mode Decomposition (EMD) and Canonical Correlation Analysis (CCA) are proposed to automatically identify eyeblink artifacts and remove them in an online setting. The proposed approaches are analysed and evaluated in terms of artifact removal a…
Development of Eco-Friendly and Self-Cleaning Lime-Pozzolan Plasters for Bio-Construction and Cultural Heritage
2020
Summarization: Nowadays, the design and use of multi-functional mortars has increased significantly, with interesting applications in the green building and cultural heritage conservation sectors. A key point for a correct adoption of these innovative materials is their behavior along time and their resistance to the weathering. The objective of this project was to define the performance and durability of innovative mortars, in order to use them correctly and to avoid irreparable damage over time. For the development of this project, lime–metakaolin and hydraulic lime–metakaolin based mortars (hereinafter called A, B), as well as A and B with the addition of nano-TiO2 and perlite (hereinaft…
Artificial Intelligence for Cybersecurity: A Systematic Mapping of Literature
2020
Due to the ever-increasing complexities in cybercrimes, there is the need for cybersecurity methods to be more robust and intelligent. This will make defense mechanisms to be capable of making real-time decisions that can effectively respond to sophisticated attacks. To support this, both researchers and practitioners need to be familiar with current methods of ensuring cybersecurity (CyberSec). In particular, the use of artificial intelligence for combating cybercrimes. However, there is lack of summaries on artificial intelligent methods for combating cybercrimes. To address this knowledge gap, this study sampled 131 articles from two main scholarly databases (ACM digital library and IEEE…
New Twists of 3D Chiral Metamaterials
2018
Rationally designed artificial materials, called metamaterials, allow for tailoring effective material properties beyond ("meta") the properties of their bulk ingredient materials. This statement is especially true for chiral metamaterials, as unlocking certain degrees of freedom necessarily requires broken centrosymmetry. While the field of chiral electromagnetic/optical metamaterials has become rather mature, the field of elastic/mechanical metamaterials is just emerging and wide open. This research news reviews recent theoretical and experimental progress concerning 3D chiral mechanical and optical metamaterials, with special emphasis on work performed at KIT.
Biodegradability Prediction of Fragrant Molecules by Molecular Topology
2016
Biodegradability is a key property in the development of safer fragrances. In this work we present a green methodology for its preliminary assessment. The structure of various fragrant molecules is characterized by computing a large set of topological indices. Those relevant to biodegradability are selected by means of a hybrid stepwise selection method to build a linear classifier. This model is compared with a more complex artificial neural network trained with the indices previously found. After validation, the models show promise for time and cost reduction in the development of new, safer fragrances. The methodology presented could easily be adapted to many quasi-big data problems in R…
Constructing Interpretable Classifiers to Diagnose Gastric Cancer Based on Breath Tests
2017
Quick, inexpensive and accurate diagnosis of gastric cancer is a necessity, but at this moment the available methods do not hold up. One of the most promising possibilities is breath test analysis, which is quick, relatively inexpensive and comfortable to the person tested. However, this method has not yet been well explored. Therefore in this article the authors propose using transparent classification models to explain diagnostic patterns and knowledge, which is acquired in the process. The models are induced using decision tree classification algorithms and RIPPER algorithm for decision rule induction. The accuracy of these models is compared to neural network accuracy.
I Sogni e le ossessioni di Michele Mari e Gianfranco Baruchello
2022
Michele Mari e Gianfranco Baruchello pubblicano un volume intitolato Sogni (2017), composto di due sezioni: una prima contiene trentasei frammenti dello scrittore, stampati su carta usomano gialla, dal titolo Oniroschediasmi e una seconda raccoglie sessantaquattro riproduzioni dei disegni di Baruchello, su carta patinata avorio, intitolata In Store. Sogni è il frutto maturo della collaborazione di due scrittori-artisti o disegnatori-letterati. L’obiettivo della mia analisi consiste nell’evidenziare il contributo di Mari al libro d’artista, mettendo in risalto le assonanze tra le due sezioni sia dal punto di vista dei motivi comuni, sia dal punto di vista delle pratiche artistiche. Per dimos…
Valdes locekļa atbildība par sabiedrībai nodarītu kaitējumu un tās noteikšanas problēmjautājumi
2016
Pēdējo gadu laikā, ņemot vērā būtiskās izmaiņas likumdošanā, kas paredz stingrāku valdes locekļu atbildības regulējumu, sabiedrībā aktuāls ir kļuvis jautājums par valdes locekļu atbildību. Lai gan likums nosaka, ka kapitālsabiedrība par savām saistībām atbild ar savu mantu, nošķirtais atbildības princips (korporatīvais plīvurs) neatbrīvo valdes locekli, kurš rīkojies prettiesiski, no pienākuma atlīdzināt zaudējumus. Lai gan likums nosaka, ka valdes loceklim ir jārīkojas kā krietnam un rūpīgam saimniekam, šī ģenerālklauzula rada nevienādu viedokli sabiedrībā, kā arī judikatūrā, līdz ar to nepieciešams noskaidrot, kādiem būtu jābūt atbildības noteikšanas priekšnosacījumiem, lai pierādītu, ka …
Ultra-sensitive chiral sensing and analysis from the nanoscale to the earth’s atmosphere
2020
Chirality plays an essential role in life and, therefore, in modem science. I’ll present novel technologies for ultra-sensitive, absolute, chiral sensing and analysis, in all phases, from the nanoscale to the earth’s atmosphere.
