A novel device for assessing the health risk caused by hand-arm vibrations in olives harvesting
2012
The mechanization of olive harvesting is very important both to reduce the costs of production and to assure the oil quality because the manual harvest does not allow to operate at the right time and also need a long period to be completed. The use of portable shakers, that are spreading more than others typologies, can give a solution to the problem. However, the use of such equipment may involve risk of exposure to hand-transmitted vibration. The aim of this study was to assess the level of exposure to hand-arm vibration of the operators using portable shakers (reference standards UNI EN ISO 5349-1:2004, Italian Low Decree 81/2008). The research presented here concerns the definition of a…

Design and Characterization of Effective Ag, Pt and AgPt Nanoparticles to H₂O₂ Electrosensing from Scrapped Printed Electrodes.
2019
The use of disposable screen-printed electrodes (SPEs) has extraordinarily grown in the last years. In this paper, conductive inks from scrapped SPEs were removed by acid leaching, providing high value feedstocks suitable for the electrochemical deposition of Ag, Pt and Ag core-Pt shell-like bimetallic (AgPt) nanoparticles, onto screen-printed carbon electrodes (ML@SPCEs, M = Ag, Pt or AgPt, L = metal nanoparticles from leaching solutions). ML@SPCEs were characterized by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. The results were compared to those obtained when metal nanoparticles were synthesised using standard solutions of metal salts (MS@…
Revisiting the cross‐sectional and prospective association of physical activity with body composition and physical fitness in preschoolers: A composi…
2022
Background Information is limited for the benefits of physical activity (PA) in preschoolers. Previous research using accelerometer-assessed PA may be affected for multicollinearity issues. Objectives This study investigated the cross-sectional and prospective associations of sedentary behaviour (SB) and PA with body composition and physical fitness using compositional data analysis. Methods Baseline PA and SB were collected in 4-year-old (n = 315) using wrist-worn GT3X+ during seven 24 h-periods. Body composition (air-displacement plethysmography) and physical fitness (PREFIT test battery) were assessed at baseline and at the 12-month follow-up. Results Increasing vigorous PA at expenses o…
Reflectance Measurement Method Based on Sensor Fusion of Frame-Based Hyperspectral Imager and Time-of-Flight Depth Camera
2022
Hyperspectral imaging and distance data have previously been used in aerial, forestry, agricultural, and medical imaging applications. Extracting meaningful information from a combination of different imaging modalities is difficult, as the image sensor fusion requires knowing the optical properties of the sensors, selecting the right optics and finding the sensors’ mutual reference frame through calibration. In this research we demonstrate a method for fusing data from Fabry–Perot interferometer hyperspectral camera and a Kinect V2 time-of-flight depth sensing camera. We created an experimental application to demonstrate utilizing the depth augmented hyperspectral data to measu…
Bezvadu saziņas kanālu izmaiņas laikā ārējo faktoru ietekmē
2018
Bakalaura darba “Bezvadu saziņas kanālu izmaiņas laikā ārējo faktoru ietekmē” mērķis ir izveidot risinājumu, ar kura palīdzību var attēlot bezvadu saziņas kanālu izmaiņas. Mērķa sasniegšanai autors ir izvirzījis vairākus uzdevumus. Sākumā tiek veikta literatūras izpēte par to kā tiek veikta bezvadu kanālu kartēšana, izmantojot bezvadu sensoru tīklu. Tālāk autors izstrādā eksperimentālo programmatūru priekš XM1000 sensoru mezgla, izmantojot MansOS operētājsistēmu. Autors darbā apraksta eksperimenta veikšanu, izmantojot Elektronikas un datorzinātņu institūta bezvadu sensoru tīkla testa gultni, un kā tiek veikta no bezvadu sensoru tīkla iegūto datu vizualizācija. Darbu autors noslēdz izdarot s…
Le processus de choix alimentaire et ses déterminants : vers une prise en compte des caractéristiques psychologiques du consommateur
2006
This thesis aims to explore new research opportunities in the food field, proposing to explicitly include psychological factors as potential determinants of food choice process. It notes the consequences of the central role of pleasure in the mechanisms of ingestion, and the specific role of taste: the highly emotional nature of food consumption leads then to retain experiential approach and more specifically sensory marketing as a framework. The issue of research aims to investigate how sensory stimuli and the information associated with the product combine to influence, in a differentiated manner depending on the individual, consumption behavior.Methodologically, the research combines con…
Quand les institutions culturelles s´ouvrent au marketing sensoriel ... et s´en défendent : enjeux et paradoxes.
2007
: Stimulate the audience sensoriality seems to be a new spearhead for a lot of cultural institutions. In this way, it is important to understand how the stimulation of the five senses of the audience could be interesting for managers in the cultural field. We wish, within this article, to improve this analysis. Accordingly, we will try, in a first part, to define this "sensory" trend of consumption and to clarify its stakes in comparison with the work completed in other marketing's fields. In a second part, we will appreciate the consequences of this tendency in terms of managerial practices for the professionals of the cultural sector. In a third and last part, we will present the principa…

Multi-Chip RFID Antenna Integrating Shape-Memory Alloys for Detection of Thermal Thresholds
2011
Low-cost wireless measurement of objects' temperature is one of the greatest expectation of radiofrequency identification technology for the so many applications in cold supply-chain control and safety assessment in general. In this context, the paper proposes a dual-chip UHF tag embedding shape memory alloys (SMA) able to transform the variation of the tagged item's temperature into a permanent change of antenna radiation features. This event-driven antenna is hence able to selectively activate the embedded microchips according to the temperature above or below a given threshold. A general design methodology for the resulting two-ports tag antenna is here introduced and then applied to pro…
