Research and Implementation of Energy Dispersal Algorithm for DRM System
2020
The article investigates the randomization algorithm of the OFDM signal energy used in modern digital broadcasting systems. Transmission part of the DRM system was modeled in MATLAB/Simulink software environment, bit sequences allocation tests were conducted using the original information signal and the corresponding modulation symbols with a scrambling algorithm and without it.
“Facebocrastination”? Predictors of using Facebook for procrastination and its effects on students’ well-being
2016
Procrastinating with popular online media such as Facebook has been suggested to impair users well-being, particularly among students. Building on recent procrastination, self-control, and communication literature, we conducted two studies (total N=699) that examined the predictors of procrastination with Facebook as well as its effects on students academic and overall well-being. Results from both studies consistently indicate that low trait self-control, habitual Facebook checking, and high enjoyment of Facebook use predict almost 40 percent of the variance of using Facebook for procrastination. Moreover, results from Study 2 underline that using Facebook for the irrational delay of impor…
Ego sum, ego existo. Per una rilettura della res cogitans
2016
The notion of res cogitans has constituted a privileged critical objective of readings of modern subjectivity in a deconstructionist key, coming to act as a term in which there seem to merge, in a sort of fatal alliance, hyperconscientialism, reification, solipsism and everything the contemporary culture attributes to bad metaphysics, or even to metaphysics tout court. However, also and above all when it is understood within the ontologically strong meaning of substantia, the Cartesian reference to res cogitans does not necessarily denote the simple outcome of the I folding back into alleged and undisturbed autonomy. It also proves to be the locus in which what is challenged is precisely th…
SENTINEL-1 for wheat mapping and soil moisture retrieval
2015
The main objective of this study is to assess the use of Sentinel-1 (S-1) data for surface soil moisture (SSM) retrieval and wheat mapping (WM) at high spatial resolution (e.g. 100–500m), which constitute valuable information for improving crop yield forecast at large scale. A knowledge based classification method and a SSM retrieval algorithm, developed in view of the European Space Agency Sentinel-1 mission, have been applied to a time series of S-1A data collected from October 2014 to April 2015 over a well-documented agricultural site in southern Italy. In particular, observations of SSM content recorded by a network of ground stations deployed in an experimental farm have been used to …
Synthesis and degradation of type IV collagen in rat skeletal muscle during immobilization in shortened and lengthened positions
2003
Aim: Type IV collagen is a major protein in basement membranes surrounding and supporting skeletal muscle cells. In the present study, we tested the hypotheses that immobilization down-regulates synthesis and up-regulates degradation of type IV collagen in skeletal muscle. Methods: mRNA level and concentration of type IV collagen as well as mRNA levels and activities of proteins involved in its degradation were analysed from soleus (SOL), gastrocnemius (GAS) and extensor digitorum longus muscles after immobilization in shortened and lengthened positions for 1, 3 and 7 days. Results: Following immobilization, type IV collagen mRNA level was decreased in SOL and GAS suggesting down-regulat…
Triblock SEBS/DVB crosslinked and sulfonated membranes: Fuel cell performance and conductivity
2021
[EN] A set of styrene-ethylene-butylene-styrene triblock copolymer (SEBS) membranes with 10 or 25 wt.% divinyl-benzene (DVB) as a crosslinking agent were prepared and validated. Physicochemical characterization revealed suitable hydrolytic and thermal stability of photo-crosslinked membranes containing 25%wt. DVB and post-sulfonated. These compositions were evaluated in H2/O2 single cells, and electrical and proton conductivities were furtherly assessed. The membranes with the milder post-sulfonation showed greater proton conductivity than those with excessive sulfonation. In terms of electrical conductivity, a universal power law was applied, and the values obtained were low enough for bei…

Vanhan ihmisen haavoittuvuus ja hoivateknologia kodissa
2022
Tässä luvussa tarkastelemme kotona asuvien vanhojen ihmisten, kotihoidon asiakkaiden, kokemuksia kotiin tuodusta hoivateknologiasta. Kysymme, mitä tapahtuu vanhan ihmisen hoivalle ja haavoittuvuudelle, kun teknologia tulee kotiin osana kotihoidon työntekijöiden hoivatyötä. Näkökulmamme hoivan teknologisoitumiseen on sen sosiaalisissa, ruumiillisissa ja organisatorisissa seurauksissa, joita lähestymme hoivan digitaalisen maiseman käsitteen kautta (digital landscapes of care) (Milligan & Wiles 2010; Lindberg & Carlsson 2018). Tarkastelun kohteena olevat hoivateknologiat ovat etäseurantajärjestelmä “Kukkatolppa”, videoneuvottelupuhelinjärjestelmä “Kuvapuhelin” ja siihen kytketty sisältöpalvelu…
Varkaus yhteiskunnallisten murrosten näyttämönä 1900-luvun alusta nykypäivään
2020
Tässä kymmenestä artikkelista koostuvassa kokoomateoksessa tarkastellaan Varkautta rakennemuutoksen kanssa kamppailevana pienenä kaupunkina historiallisia dokumentteja sekä vuosina 2016–2017 kerättyjä kysely- ja haastatteluaineistoa hyödyntäen. Pitkän teollisuushistorian omaava Varkauden kaupunki on tämän vuosituhannen ensimmäisinä vuosikymmeninä menettänyt suuren osan teollisista työpaikoistaan ja sen väestö on supistunut voimakkaasti. Kuitenkin koko aikuisväestöä edustava kysely kertoo, että varkautelaiset ovat tyypillisesti tyytyväisiä työhönsä, sosiaalisiin suhteisiinsa ja elämäänsä muutenkin. Varkaus nähdään turvallisena ja hyvän elämän puitteet tarjoavana asuinpaikkana. Hyvinvoinnin t…
Testing the direct and moderator effects of the stressor-detachment model over one year : A latent change perspective
2018
ABSTRACTTo test the direct and moderator effects of the stressor–detachment model from a long-term perspective, we investigated whether workload and detachment are related to changes in exhaustion and sleep difficulties over one year. We also examined whether detachment attenuates the relationship between high workload and these outcomes both cross-sectionally and over time. Questionnaire data with 1722 respondents at Time 1 and 1182 respondents at Time 2 were collected. We used a latent change score approach to analyse the data in order to identify intra-individual change among the studied constructs. Our results showed that high workload and low detachment at baseline were related to an i…
