«Questa è la città di Augusto». Archi e processioni a Leptis Magna
2020
A recent study on the Trajan's arch at Leptis Magna mentions a second arch of Tiberius, along a street which runs parallel to the main cardo, where the more famous “twin” of this arch is located. The study also mentions a structure, an arch as well, posed at the same place where the tetrapyle of Trajan was erected. These three arches mark the three vertices of a quadrilateral of streets involving the main places of the public consent through the Imperial House. It is not a case that this predecessor of the Trajan's arch lies on the crossway among the main cardo and a way with goes to the street that separes the Theatre, the fourth vertex of the quadrilateral, from the porticus post scaenam.…
Fuzzy sliding mode control design for a class of disturbed systems
2014
This paper discusses the problem of the fuzzy sliding mode control for a class of disturbed systems. First, a fuzzy auxiliary controller is constructed based on a feedback signal not only to estimate the unknown control term, but also participates in the sliding mode control due to the fuzzy rule employed. Then, we extend our theory into the cases, where some kind of system information can not be obtained, for better use of our theoretical results in real engineering. Finally, some typical numerical examples are included to demonstrate the effectiveness and advantage of the designed sliding mode controller. Refereed/Peer-reviewed
HPLC Determination of Polyphenols from Calendula officinalis L. Flowers
2017
Abstract Romanian spontaneous flora provides a lot of resources for the determination of different chemical compounds. This study uses flower samples from Calendula officinalis L. extracted through maceration. The chemical compounds determined were: (+)-catechin, caffeic acid, chlorogenic acid, cinnamic acid, ferulic acid, gallic acid, rutin, resveratrol and quercetin. They were analyzed by using an optimized HPLC method. (+)-Catechin, caffeic acid, chlorogenic acid and quercetin could not be identified in the analyzed samples. The greatest amount of phenolic compound found was rutin and the smallest quantity was determined for ferulic acid. The quantified compounds have proven to have bene…
Time Unification on Local Binary Patterns Three Orthogonal Planes for Facial Expression Recognition
2019
International audience; Machine learning has known a tremendous growth within the last years, and lately, thanks to that, some computer vision algorithms started to access what is difficult or even impossible to perceive by the human eye. While deep learning based computer vision algorithms have made themselves more and more present in the recent years, more classical feature extraction methods, such as the ones based on Local Binary Patterns (LBP), still present a non negligible interest, especially when dealing with small datasets. Furthermore, this operator has proven to be quite useful for facial emotions and human gestures recognition in general. Micro-Expression (ME) classification is…
Riapertura di procedimenti interni, margine di apprezzamento, consensus europeo
2021
The contribution comments on separate opinions rendered by Judge Pinto dealing with the reopening of domestic civil processes in which violations of ECHR have occurred.
Traffico di migranti via mare, poteri di polizia nelle azioni di contrasto e tutela della dignità della persona
2016
Di “stanchezza della catastrofe” ha di recente parlato Zygmund Bauman, a proposito dello stratificarsi parossistico delle tragedie del mare sulle rotte dell’immigrazione irregolare. Il fenomeno frastagliato del traffico di esseri umani via mare ha evidenziato lo stratificarsi di strategie criminali il cui hardware è costituito da una nave madre, armata dall’organizzazione dedita al traffico e deputata a incrociare in mare aperto, e da una flotta proteiforme di imbarcazioni di appoggio, che assicurano i trasbordi dei migranti entrando in acque territoriali. Il rischio che la navigazione della nave madre nelle sole acque internazionali possa virtualmente vanificare l’esercizio efficiente dell…
Biomass Waste Processing into Artificial Humic Substances
2021
Abstract To address the biomass waste processing problem and transform it into refractory forms of carbon, recently suggested hydrothermal carbonization (HTC) of biomass in alkaline environment can be considered as a prospective and climate neutral approach. Biomass HTC provides possibilities to obtain form of biochar (hydrochar) and artificial humic substances, however the conditions of the HTC have not been much studied. Optimization by Response Surface Methodology of the HTC using microwave treatment with three experimental variables (treatment temperature, length of microwave treatment, amount of biomass per volume) provides the possibility to significantly increase the yield of humic s…
Processing Mechanism of Chinese Verbal Jokes : Evidence from ERP and Neural Oscillations
2019
The cognitive processing mechanism of humor refers to how the system of neural circuitry and pathways in the brain deals with the incongruity in a humorous manner. The past research has revealed different stages and corresponding functional brain activities involved in humor-processing in terms of time and space dimensions, highlighting the effects of the time windows of about 400 ms, 600 ms, and 900 ms. However, much less is known about humor processing in light of the frequency dimension. A total of 36 Chinese participants were recruited in this experiment, with Chinese jokes, nonjokes, and nonsensical sentences used as the stimuli. The experimental results showed that there were signific…
Modeling and Design of Membrane Integrated Processes for HCl and Metals Recovery from Pickling Solutions
2018
Hydrochloric acid pickling is a common practice in steel manufacturing industry. During the process, acid is consumed to dissolve surface oxides and metals are accumulated in the solution. This fact leads to a process efficiency decrease. Continuous regeneration of pickling solutions enhances process rate and performance, but also minimises the highly expensive and environmentally risky wastewater disposal. The recovery of valuable substances (e.g. acid and metals) can be accomplished by coupling diffusion dialysis (DD) and membrane distillation (MD) technologies. In the present work, a steady state process simulator for the integrated process has been developed. The aim is to analyze and p…
Estimating field-saturated soil hydraulic conductivity by a simplified Beerkan infiltration experiment
2014
Field-saturated soil hydraulic conductivity, Kfs, is highly variable. Therefore, interpreting and simulating hydrological processes, such as rainfall excess generation, need a large number of Kfs data even at the plot scale. Simple and reasonably rapid experiments should be carried out in the field. In this investigation, a simple infiltration experiment with a ring inserted shortly into the soil and the estimation of the so-called a* parameter allowed to obtain an approximate measurement of Kfs. The theoretical approach was tested with reference to 149 sampling points established on Burundian soils. The estimated Kfs with the value of first approximation of a* for most agricultural field s…
