Detecting rottenness caused by Penicillium genus fungi in citrus fruits using machine learning techniques
2012
Penicillium fungi are among the main defects that may affect the commercialization of citrus fruits. Economic losses in fruit production may become enormous if an early detection of that kind of fungi is not carried out. That early detection is usually based either on UltraViolet light carried out manually. This work presents a new approach based on hyperspectral imagery for defect segmentation. Both the physical device and the data processing (geometric corrections and band selection) are presented. Achieved results using classifiers based on Artificial Neural Networks and Decision Trees show an accuracy around 98%; it shows up the suitability of the proposed approach.
The AVL-mode: a safe closed loop algorithm for ventilation during total intravenous anesthesia.
1994
The Adaptive Lung Ventilation Controller (ALV-Controller) represents a new approach to closed loop control of ventilation. It is based on a pressure controlled ventilation mode. Adaptive lung ventilation signifies automatic breath by breath adaptation of breathing patterns to the lung mechanics of an individual patient. The specific goals are to minimize work of breathing, to maintain a preset alveolar ventilation and to prevent the occurrence of intrinsic PEEP. We ventilated 5 patients undergoing major abdominal procedures using ALV. ALV was tolerated well in all patients. Alveolar ventilation was preset between 5500 and 6500 ml/min. Serial dead space (Vds) and respiratory time constant (r…
Adulterare l’India: una prospettiva antropologica sui racconti di viaggio di Moravia e Pasolini
2013
Nell’ambito della produzione/ricezione testuale il concetto di “adulteramento” puo assumere valenze diverse. Tuttavia, va rilevato che il suo utilizzo puo far emergere delle criticita: se impiegato per descrivere un qualche “cambiamento” nel processo di testualizzazione, ossia di produzione di un testo, esso pare individuare la presa di distanza rispetto a un’idea o a una forma “originaria”, ovvero pone il problema del rapporto fra testo e contesto e fra autenticita e copia. Se lo si osserva da una prospettiva antropologica e semiotica, il concetto di adulteramento implica percio almeno un’“alterita” cui rivolgersi e un’“autenticita” rispetto a cui prendere le distanze, ponendo dei problemi…
Les mesures de la relation formation-emploi
2015
National audience; Depuis les années 1960, l'analyse de la relation formation-emploi a fait en France l'objet de nombreux travaux, à partir notamment de grandes enquêtes statistiques comme les enquêtes emploi de l'INSEE ou les enquêtes du Céreq sur l'insertion des jeunes. Plusieurs mesures du lien formation-emploi ont été proposées, certaines d'entre elles se référant plus au moins explicitement à une logique adéquationniste qui a émergé lors des travaux des IVe et Ve Plans. Toutes les mesures montrent cependant que la relation formation-emploi est plurielle et que l'adéquation d'une formation à un emploi, à l'exception de quelques professions, n'est pas la norme sur le marché du travail.
Determinants and efficiency of Pakistan's chemical products' exports: An application of stochastic frontier gravity model.
2019
The estimation of efficiency of industry-specific exports is very important to find exports' gap and to frame exports promotion policy for targeted industry. This study attempts to investigate the main determinants of chemical products' exports of Pakistan with 62 trading partners by applying Stochastic Frontier Analysis (SFA) on an augmented gravity model for a period 1995-2015. The results corroborate that chemical products' exports follow gravity patterns. This study finds a negative and significant impact of import tariff on exports of chemical products while the positive impact of devaluation has been observed. Further, the estimations also take into account the impact of Preferential …
Vector-borne and zoonotic infections and their relationships with regional and socioeconomic statuses: An ID-IRI survey in 24 countries of Europe, Af…
2021
Background: In this cross-sectional, international study, we aimed to analyze vector-borne and zoonotic infections (VBZI), which are significant global threats. Method: VBZIs’ data between May 20–28, 2018 was collected. The 24 Participatingcountries were classified as lower-middle, upper-middle, and high-income. Results: 382 patients were included. 175(45.8%) were hospitalized, most commonly in Croatia, Egypt, and Romania(P = 0.001). There was a significant difference between distributions of VBZIs according to geographical regions(P < 0.001). Amebiasis, Ancylostomiasis, Blastocystosis, Cryptosporidiosis, Giardiasis, Toxoplasmosis were significantly more common in the Middle-East while B…

H-2, H-3(+) and the age of molecular clouds and prestellar cores
2012
Measuring the age of molecular clouds and prestellar cores is a difficult task that has not yet been successfully accomplished although the information is of paramount importance to help in understanding and discriminating between different formation scenarios. Most chemical clocks suffer from unknown initial conditions and are therefore difficult to use. We propose a new approach based on a subset of deuterium chemistry that takes place in the gas phase and for which initial conditions are relatively well known. It relies primarily on the conversion of H 3 + into H 2D + to initiate deuterium enrichment of the molecular gas. This conversion is controlled by the ortho/para ratio of H2 that i…
Minidisk dynamics in accreting, spinning black hole binaries: Simulations in full general relativity
2021
We perform magnetohydrodynamic simulations of accreting, equal-mass binary black holes in full general relativity focusing on the impact of black hole spin on the dynamical formation and evolution of minidisks. We find that during the late inspiral the sizes of minidisks are primarily determined by the interplay between the tidal field and the effective innermost stable orbit around each black hole. Our calculations support that a minidisk forms when the Hill sphere around each black hole is significantly larger than the black hole's effective innermost stable orbit. As the binary inspirals, the radius of the Hill sphere decreases, and minidisk sconsequently shrink in size. As a result, ele…
