Agents driven smart sensors
2017
Any physical area (like schools, home, hospitals etc.) that uses either mobile devices, sensors, embedded systems or computers to gather information from the users and the environment and eventually, adapt according to the new information gained. [1] Smart spaces compromises of heterogeneous hardware which often leads to the issues of interoperability. One way of reducing the heterogeneity between the sensors is to introduce the semantic interface as sensors default interface. Semantic Web provides a common interface and for-mat for data representation so that one can decrease the heterogeneity of data and increase data reusability. [2] With the Smart Spaces, it is important to use only the…
Minimum detection limits and applications of proton and helium induced X-ray emission using transition-edge sensor array
2017
Abstract We have determined minimum detection limits, MDLs, for elements 14 ⩽ Z ⩽ 86 using a transition-edge sensor array, TES array, and as a comparison using an Amptek X-123SDD silicon drift detector, SDD. This was done using a 3 MeV proton beam and a 5.1 MeV helium beam. MDLs were determined for a thin film sample on top of C substrate, and for a bulk sample containing mostly Al. Due to the higher peak-to-background ratio, lower detection limits were obtainable using the TES array for most of the elements. However, for elements 30 ⩽ Z ⩽ 45 the performance of the TES array was not as good as the SDD performance. This is due to the limitations of the TES used at energies >10 keV. The great…
Alkylthio-tetrasubstituted μ-Nitrido Diiron Phthalocyanines: Spectroelectrochemistry, Electrical Properties, and Heterojunctions for Ammonia Sensing.
2020
Alkylthio-tetrasubstituted μ-nitrido diiron phthalocyanine complexes are synthesized with n-butyl, iso-butyl, tert-butyl, and n-hexadecyl alkyl moieties. For the first time, a spectroelectrochemical investigation of μ-nitrido diiron phthalocyanines is achieved at all the redox steps. The complexes are stable in all their redox states, unlike their unsubstituted analogues. The interest of the present complexes is to prepare sensing devices by a solution processing method. Films are characterized by electronic absorption and Raman spectroscopies. Electrical measurements on resistors show the highly resistive behavior of these complexes, whatever the chain length. However, when combined with t…
Krūšu rajonā novietoto sensoru pielietojums slimnīcā iegūto izgulējumu novēršanas pasākumos
2020
Darba aktualitāte: Izgulējumi ir viena no visizplatītākajām slimnīcā iegūtām slimībām, kas var novest līdz dzīves pasliktināšanai un pat nāvei. Profilaktiskie pasākumi var samazināt izgulējumu biežumu veidošanos. Darba mērķis: Izvērtēt valkājamo sensoru nozīmi slimnieka pozas vērtēšanā 24 stundu laika periodā pētot pacienta pagriešanās laiku un apjomu. Materiāli un metodes: Prospektīvājā pētijumā tika pētīti RAKUS Stacionāra ”Biķernieki” iegūti dati no 15 valkājamiem Movesense sensoriem, kas tika novietoti uz pacienta krūšu kaula laika posmā no 10.02.20 līdz 12.03.20, pēc kā tika ieviesta ārkārtējā situācija un visi klīniskie pētījumi tika apstādināti. Sensors tika novietots uz krūšu kaula …
Miniature MOEMS hyperspectral imager with versatile analysis tools
2019
The Fabry-Perot interferometers (FPI) are essential components of many hyperspectral imagers (HSI). While the Piezo-FPI (PFPI) are still very relevant in low volume, high performance applications, the tunable MOEMS FPI (MFPI) technology enables volume-scalable manufacturing, thus having potential to be a major game changer with the advantages of low costs and miniaturization. However, before a FPI can be utilized, it must be integrated with matching optical assembly, driving electronics and imaging sensor. Most importantly, the whole HSI system must be calibrated to account for wide variety of unwanted physical and environmental effects, that significantly influence quality of hyperspectral…
George Edward Moore and the philosophy of “common sense”: idealism and anti-idealism
2023
Se prendiamo in esame la storia del pensiero europeo del XX secolo, l’anno della frattura tra idealismo e anti-idealismo è rappresentato dal 1903, quando Bertrand Russell pubblica “The Principles of Mathematics”, dando corso al neo-positivismo, che nel continente europeo si sarebbe sviluppato come empirismo logico con i rappresentanti del Circolo di Vienna, del Circolo di Berlino della Scuola di Leopoli-Varsavia. Nello stesso anno 1903 George Edward Moore, nella rivista “Mind”, pubblica il saggio “The Refutation of Idealism”; ma non solo, perché ancora nel 1903 dà alle stampe il volume “Principia Ethica”. A Moore, non meno che a Russell, va prestata la dovuta attenzione per l’elaborazione d…
Where do food likes and dislikes come from?
2020
Where do food likes and dislikes come from ? In other words, what are the factors that could explain why someone likes or dislikes a given food ? Most of the hedonic reactions to sensory stimulations brought by foods and, as a result reactions to foods carrying these sensory properties are learned through different learning mechanisms. The efficiency of these learning mechanisms mat depend on individual characteristics, in particular on the sensitivity to different sensory properties. Not all learnings are related to experiments with the food itself; many leamings depend on interactions within the family or social environment. Finally, cognitive determinants play also a role and, in particu…
Idrogeli a base di xyloglucano per la produzione di medicazioni avanzate nel trattamento delle ferite
2018
In questo lavoro sono stati preparati film sottili di idrogelo (reticolati fisicamente o chimicamente) a base di xyloglucano (XG) e XG/polivinilalcol (PVA), a cui si è aggiunto glicerolo come plasticizzante. Lo xyloglucano è un polisaccaride di origine vegetale, caratterizzato da una catena principale di (1,4)--Dglucosio con ramificazioni laterali di (1-6)-α-xilosio, parzialmente sostituite con (1-2)–β galattosio. E’ stata indagata la possibilità di modulare la densità di reticolazione dell’idrogelo per ottenere il miglior compromesso tra resistenza meccanica e flessibilità, l’integrità strutturale nel tempo e la capacità di assorbire fluidi biologici o trattenere l’umidità. Inoltre, ne è …
Iegultās iekārtas un programmatūra veselības datu pārraudzībai rehabilitācijas laikā
2015
Bakalaura darbs apskata sekojošu problēmu: pacientu veselības rādītāju pārraudzība rehabilitācijas iziešanas laikā. Autors apskata menisku bojājumu pēcoperāciju rehabilitācijas procesu ar mērķi definēt pārraudzībai nepieciešamus veselības rādītājus. Pirms risinājuma izstrādes tika veikta veselības speciālistu un bijušo pacientu intervēšana. Tas palīdzēja autoram aplūkot un izanalizēt situāciju no abām pusēm – saprast kādas grūtības pastāv fizioterapeitu darbā un atrast ar kādām problēmām saskarās pacienti pēc ceļa locītavas operācijas. Darba ietvaros tika veikta esošo risinājumu analīze ar mērķi aplūkot izmantotas tehnoloģijas un atrast šo izstrāžu priekšrocības un nepilnības. Apskatot un s…
Salt release monitoring with specific sensors in "in vitro" oral and digestive environments from soft cheeses
2012
International audience; The objective of the present work is to demonstrate the interest and the feasibility of the measurement of NaCl concentrations in soft cheeses and in particular an in vitro digestion process by the use of chemical sensors. The analyzed matrices were the commercial Italian mozzarella cheeses and domestic cheese base models. The classification of mozzarellas was performed according to their salinity, while the breakdown of cheese base models has been followed both at initial steps of digestion in artificial mouth dispositive mimicking the oral sphere and in a gut-imitating digester (TIM-1). During the breakdown of soft cheese in the digester, the estimated values for N…
