PPG/ECG Multisite Combo System Based on SiPM Technology
2019
Two versions of a PPG/ECG combined system have been realized and tested. In a first version a multisite system has been equipped by integrating 3 PPG optodes and 3 ECG leads, whereas in another setup a portable version has been carried out. Both versions have been realized by equipping the optical probes with SiPM detectors. SiPM technology is expected to bring relevant advantages in PPG systems and overcome the limitations of physiological information extracted by state of the art PPG, such as poor sensitivity of detectors used for backscattered light detection and motion artifacts seriously affecting the measurements repeatability and pulse waveform stability. This contribution presents t…
Measurements of Silicon Photomultipliers Responsivity in Continuous Wave Regime
2013
We report on the electrical and optical characterization, in continuous wave regime, of a novel class of silicon photomultipliers fabricated in standard planar technology on a silicon p-type substrate. Responsivity measurements, performed with an incident optical power down to tenths of picowatts, at different reverse bias voltages and on a broad (340–820 nm) spectrum, will be shown and discussed. The device temperature was monitored, allowing us to give a physical interpretation of the measurements. The obtained results demonstrate that such novel silicon photomultipliers are suitable as sensitive power meters for low photon fluxes.
StalAge – An algorithm designed for construction of speleothem age models
2011
Abstract Here we present a new algorithm ( StalAge ), which is designed to construct speleothem age models. The algorithm uses U-series ages and their corresponding age uncertainty for modelling and also includes stratigraphic information in order to further constrain and improve the age model. StalAge is applicable to problematic datasets that include outliers, age inversions, hiatuses and large changes in growth rate. Manual selection of potentially inaccurate ages prior to application is not required. StalAge can be applied by the general, non-expert user and has no adjustable free parameters. This offers the highest degree of reproducibility and comparability of speleothem records from …
Changes in achievement values from primary to lower secondary school among students with and without externalizing problems
2017
This study examined the effect of students' externalizing problems on changes in values that they attach to math across the transition from primary to lower secondary school. Data pertaining to externalizing problems and to intrinsic, attainment, and utility values in math were gathered using the self-ratings of students in Grades 6 and 7. The analysis involved a comparison between students who reported persistent high externalizing problems before and after the transition (n = 63; 59% boys) and those who had low or non-existent externalizing problems before and after the transition (n = 1352; 50% boys). The results of a mixed-design analysis of covariance (ANCOVA) showed uniformly that stu…
Children’s beliefs concerning their school performance at the end of the first grade in Finland
2022
This study examines primary-school children’s beliefs about their school performance at the end of their first school year in Finland and feedback that they have received, and furthermore possible gender differences between these beliefs. Children from Grade 1 (N = 544), approximately 7 years old, were interviewed. The data were assessed using problem-driven content analyzis and inductive reasoning. The analyzis revealed ten categories of children’s beliefs regarding their school success and failure. The results showed that more than one-third of the children believed that they were succeeding well at school. More boys than girls mentioned that they succeeded in mathematics, and more girls …
The Yearly Land Cover Dynamics (YLCD) method: An analysis of global vegetation from NDVI and LST parameters
2009
NDVI (Normalized Difference Vegetation Index) has been widely used to monitor vegetation changes since the early eighties. On the other hand, little use has been made of land surface temperatures (LST), due to their sensitivity to the orbital drift which affects the NOAA (National Oceanic and Atmospheric Administration) platforms flying AVHRR sensor. This study presents a new method for monitoring vegetation by using NDVI and LST data, based on an orbital drift corrected dataset derived from data provided by the GIMMS (Global Inventory Modeling and Mapping Studies) group. This method, named Yearly Land Cover Dynamics (YLCD), characterizes NDVI and LST behavior on a yearly basis, through the…
Entrevista a Ernest Garcia i Joan Martínez-Alier: “Per conservar la llibertat hem d’aprendre a deixar de creure en l’abundància i el creixement econò…
2020
El creixement econòmic ha produït canvis en el metabolisme social. L’extracció i ús de recursos naturals i les deixalles, emanacions o residus estan generant cada vegada més conflictes socioambientals i ecològic-distribuïts, tant a escala global com a escala local. Tanmateix, els recursos s’estan exhaurint i cada vegada es fa més evident que la premissa de conciliar creixement econòmic i protecció del medi ambient no és, ni serà, realitzable. Això ha produït canvis i polaritzacions en la consciència col·lectiva. Per una banda, hi ha reaccions del tipus negacionisme extrem i de destrucció ambiental. I, per altra, reaccions de col·lapse. Conversem amb Joan Martínez-Alier, catedràtic i investi…
Lo spazio ospedaliero: criteri progettuali e tendenze in atto
2010
The research defines features and architectural qualities of the contemporary hospital buildings and focalizes the spaces supporting the therapeutic activity. The study of typological and theoretical contributions and the analysis of representative examples of recent architecture explain the meaning of the changes. A system of evaluating architectural qualities is useful to understand the future development and set up the guidelines for design.
Stationary and non-stationary probability density function for non-linear oscillators
1997
A method for the evaluation of the stationary and non-stationary probability density function of non-linear oscillators subjected to random input is presented. The method requires the approximation of the probability density function of the response in terms of C-type Gram-Charlier series expansion. By applying the weighted residual method, the Fokker-Planck equation is reduced to a system of non-linear first order ordinary differential equations, where the unknowns are the coefficients of the series expansion. Furthermore, the relationships between the A-type and C-type Gram-Charlier series coefficient are derived.
