Different kinds of embodied language: A comparison between Italian and Persian languages
No full textIt is debated whether only concrete but also abstract, figurative sentences, e.g.: “She grasps the cup” vs. “She grasps the concept”, are grounded in the sensorimotor system. Importantly, studies on sentences with action verbs and motor system activation have been conducted so far only with WEIRD samples (Western cultures, in North American and European countries). The aim of our work is to investigate the relationship between language and motor responses using both concrete and abstract sentences in Italian and Persian languages. In the present study, Italian and Persian participants were asked to read the sentences on the screen. The sentences referred either literally or metaphorically to motor actions. They were accompanied by a video displaying a movement that could be congruent or incongruent with the one described in the sentence. Participants were asked to re-execute the movement observed and subsequently they had to perform the task evaluating whether the sentence made sense or not. In the Italian sample a strong effect of concreteness was present, especially in the congruent but also in the incongruent condition. In the Persian sample, instead, there was an inhibition effect of congruent trials, particularly with concrete sentences, and in the incongruent trials no difference in RTs between abstract and concrete sentences was present. Results indicate that cross-cultural differences have to be taken into account when investigating the relationship between language and action
A composition estimator for multicomponent distillation columns — development and experimental test on ternary mixtures
No full textA nonlinear extended Kalman filter has been developed to infer the outlet composition of a ternary distillation column from temperature measurements. The reliability of the developed estimator is discussed with respect to disturbances on either steam, reflux and feed flowrates. It is shown that the accuracy of the adopted vapor-liquid equilibrium model plays a crucial role. The performance of the estimator is tested by comparison with actual outlet compositions measured in a pilot plant, where the separation of a ternary mixture of ethanol, tert-butanol and water is carried out.

LO STOCCAGGIO E L'OMOGENEIZZAZIONE DEI MATERIALI SCIOLTI: PROBLEMATICHE APPROCCIO METODOLOGICO E LORO MODELLIZZAZIONE INTERATTIVA
No full textLo stato delle conoscenze sulle questioni della omogeneizzazione e dello stoccaggio dei materiali sciolti nell’industria è stato oggetto di una approfondita ricerca bibliografica, cui ha fatto seguito una impostazione metodologica e di tecnica della modellizzazione e simulazione dei processi. Su tali basi sono stati costruiti modelli semplificati di elementi costitutivi degli impianti di omogeneizzazione. In questa nota vengono presentati i risultati essenziali dell’analisi con particolare riguardo alla metodologie adottate e all’affidabilità delle procedure seguite. Vengono quindi analizzate le problematiche connesse alla attuazione pratica della modellizzazione e simulazione su computer di un processo di omogeneizzazione e stoccaggio mediante stockpile longitudinale e si descrivono le grandi linee dell’impostazione metodologica e tecnica per la costruzione del modello dei processi e delle caratteristiche di alimentazione
HOMOGENIZATION OF RAW MATERIAL BY PRODUCTION PLANNING AND STORAGE SYSTEMS.
No full textThis study deals with the development and utilization of computer models for evaluating the extent to which variability of raw material grades can be reduced from the deposit to the processing plant. The specific case of a cement works is examined. The deposit and the elementary quarrying operations were modeled for the medium and long-term planning of production with the objective of predicting grade variability of the flow stream in time. The feeds inferred from previous modellings were used for simulating storage operations. In particular, the storage process (linear stockpile, as an alternative, blending from various heaps) was modelled in order to select the main parameters of the process to minimize grade variations of the feed to mill. The ways followed for modelling the prehomogenization process are described. The homogenization performance and efficiency in the silo stage has also been studied and an estimate made of the distribution of residence time on the basis of input and output sampling
Development of a composition estimator for binary distillation columns. Application to a pilot plant
No full textA nonlinear extended Kalman filter, which infers the compositions of the streams leaving a binary distillation column from temperature measurements, is developed. The accuracy of the distillation column model on which the estimator is based, is discussed in connection with the reliability of the obtained estimates. The estimator performance is checked by comparison with the dynamic behavior of a distillation pilot plant, where the separation of a binary mixture of ethanol and water takes place
Abstract concepts in interaction: the need of others when guessing abstract concepts smooths dyadic motor interactions
No full textAbstract concepts (ACs, e.g. 'justice') are more complex compared with concrete concepts (CCs) (e.g. 'table'). Indeed, they do not possess a single object as a referent, they assemble quite heterogeneous members and they are more detached from exteroceptive and more grounded in interoceptive experience. Recent views have hypothesized that interpersonal communication is particularly crucial to acquire and use ACs. The current study investigates the reliance of ACs/CCs representation on interpersonal behaviour. We asked participants to perform a motor interaction task with two avatars who embodied two real confederates. Before and after the motor interaction task, the two confederates provided participants with hints in a concept guessing task associated with visual stimuli: one helped in guessing ACs and the other, CCs. A control study we performed both with the materials employed in the main experiment and with other materials, confirmed that associating verbal concepts with visual images was more difficult with ACs than with CCs. Consistently, the results of the main experiment showed that participants asked for more hints with ACs than CCs and were more synchronous when interacting with the avatar corresponding to the AC's confederate. The results highlight an important role of sociality in grounding ACs
