Two-Sided Estimates of the Solution Set for the Reaction–Diffusion Problem with Uncertain Data
2009
We consider linear reaction–diffusion problems with mixed Dirichlet–Neumann–Robin conditions. The diffusion matrix, reaction coefficient, and the coefficient in the Robin boundary condition are defined with an uncertainty which allow bounded variations around some given mean values. A solution to such a problem cannot be exactly determined (it is a function in the set of “possible solutions” formed by generalized solutions related to possible data). The problem is to find parameters of this set. In this paper, we show that computable lower and upper bounds of the diameter (or radius) of the set can be expressed throughout problem data and parameters that regulate the indeterminacy range. Ou…
La città di Alphabet. Architettura per prosumers.
2021
Attraverso alcuni aspetti salienti dell’ideazione, della produzione e dell’opposizione al progetto del Toronto Quayside di Sidewalk labs, l’articolo discute l’influenza delle infrastrutture digitali per l’informazione sul progetto della casa e del quartiere. L’ampliamento delle attività svolte da remoto nello spazio domestico, enfatizzato dal quotidiano della pandemia da Covid 19, costituisce per gli oligopolisti planetari degli urban data come Alphabet un utile volano pubblicitario e un acceleratore. La fusione dei nuovi vessilli della tecnoemancipazione e della sostenibilità in ipotesi sperimentali che mirano a costruirsi sia per intero che per parti realizza un nuovo orizzonte in cui lo …
A Frequency-based Approach for Features Fusion in Fingerprint and Iris Multimodal Biometric Identification Systems
2010
The basic aim of a biometric identification system is to discriminate automatically between subjects in a reliable and dependable way, according to a specific-target application. Multimodal biometric identification systems aim to fuse two or more physical or behavioral traits to provide optimal False Acceptance Rate (FAR) and False Rejection Rate (FRR), thus improving system accuracy and dependability. In this paper, an innovative multimodal biometric identification system based on iris and fingerprint traits is proposed. The paper is a state-of-the-art advancement of multibiometrics, offering an innovative perspective on features fusion. In greater detail, a frequency-based approach result…
Noise Filtering Using Edge-Driven Adaptive Anisotropic Diffusion
2008
This paper presents a method aimed to noise removal in MRI (Magnetic Resonance Imaging). We propose an improvement of Perona and Malik's anisotropic diffusion filter. In our schema, the diffusion equation of the filter has been modified to take into account the edges direction, This allows the filter to blur uniform areas, while it better preserves the edges. Both quantitative and qualitative evaluation is presented and the results are compared with other methods.
In vitro evaluation of the antibacterial activity of cured dentin/enamel adhesive incorporating the antimicrobial agent MDPB
2010
The aim of this study was to investigate in vitro the antibacterial effect of a dentin/enamel adhesive containing MDPB (Clearfil Protect Bond) after curing and to compare it with an adhesive not containing MDPB (Clearfil SE Bond). The antibacterial effect of the cured adhesives was tested on Enterococcus faecalis by the evaluation of growth inhibition in a 48-h microplate direct contact test (DCT). The presence of antibacterial activity due to soluble components was also investigated by an agar diffusion test (ADT) performed with the adhesives cured on the surface of dentin disks. In the DCT, both the tested materials showed complete inhibition of bacterial growth until the 7-h reading, reg…
Thalamic parcellation for target identification in trans-cranial MR-guided Focused UltraSound (tcMRgFUS) thalamotomies: a preliminary probabilistc tr…
2018
Background: Trans-cranial MR-guided Focused UltraSound (tcMRgFUS) allows a neurofunctional exploration of thalamic nuclei to confirm and optimize the target before inducing a permanent brain lesion. However, the choice of the target is based on stereotactic coordinates that do not take into account the anatomical variability of each single patient. Thus, the optimization of the treatment target is based on the patient's feedback during lower power sonications. The aim of this work is to retrospectively evaluate the possible role of thalamic parcellation for the identification of the intermediate ventral nucleus (VIM) in patients undergoing tcMRgFUS. Materials and Methods: A 1.5T MR scanner …
New trends in culinary tourism - regional (Silesian) fusion cuisine
2020
This article concerns regional cuisine, mainly new ways of its presentation taking into account personal visions the preparation of certain dishes. Today, in culinary tourism there is a growing interest in regional dishes in fusion versions. The author discusses the characteristics of the regional and fusion cuisine, identifies selected Silesian dishes most often modified by chefs, presents the typology of restaurants that offer regional specialities in modern versions. The trend concerning modernized versions of regional specialities is constantly growing, as evidenced by, among others, an increasing number of restaurants specialized in such “food creations”. They are treated as a culinary…
Kulebele, śląski dog i gumiklejzy w pudełku, czyli o kuchni śląskiej w nowych odsłonach
2021
The article is devoted to Silesian cuisine which has recently become the subject of various activities focused on new ways of presenting it and reflecting directly the current global trends in gastronomy. Using two characteristic phenomena of street food and fusion cuisine, the author shows that specific dishes of Silesian cuisine have been reinvented thanks to the individual chefs’ visions. The transformation processes that have been taking place recently in the field of regional cuisines are most clearly visible in gastronomic establishments, where you can taste “old” dishes with new flavours and in new arrangements, often very surprising, such as hajer (rye flour tortilla with beef roula…
Eduardo Primo Yúfera, founder of Revista de Agroquímica y Tecnología de Alimentos and pioneer on food science and technology research in Spain.
2011
Eduardo Primo Yúfera was the founder and director of the Instituto de Agroquímica y Tecnología de Alimentos (IATA, 1957-1974) until he was appointed president of the Consejo Superior de Investigaciones Científicas (CSIC). His aim to publicize food science led him to create the Revista de Agroquímica y Tecnología de Alimentos in 1961, the forerunner of this journal, Food Science and Technology International, which he directed until 1977. Of his scientific output, 50% has been published in this journal. He is considered to be the promoter and exponent of Food Science and Technology and Chemical Ecology in Spain as well as the instigator of the country's innovation model (R&D and innovati…
Die thermische diffusion von polystyrol in verschiedenen lösungsmitteln
1969
Es wird uber Messungen von thermischen Diffusionskoeffizienten und LUDWIG-SORET-Koeffizienten von Polystyrol in den Losungsmitteln Toluol, Methylathylketon, Butylacetat und Cyclohexan berichtet. Es zeigte sich, das der rein thermisch bedingte Diffusionsprozes in Butylacetat und im Θ-Losungsmittel Cyclohexan unabhangig vom Molekulargewicht ist, wie as fur Toluol bereits fruher nachgewiesen werden konnte. Fur Methylathylketon wurde eine schwache, aber deutliche Abhangigkeit von D' vom Molekulargewicht zu D' ∼ M−0,12 gefunden. Bemerkenswerterweise verhalten sich die beiden in Bezug auf Polystyrol thermodynamisch sehr ahnlichen Losungsmittel Butylacetat und Methylathylketon in dieser Hinsicht s…
