Superresolved imaging of remote moving targets.
2006
We present a superresolving approach that allows one to exceed the diffraction limit and recover highly resolved contours of moving targets from a sequence of low-resolution images. The presented approach is suitable for remote sensing applications. The resolution decoding algorithm that is used to recover the high-resolution features of the target can be run partially via optical means and that way can be used to reduce the required computational complexity.
Powtoon animēto video skolēnu runāšanas precizitātes pilnvedei angļu valodas stundās 7. klasē
2019
Runāšanas prasmes tiek uzskatītas par vienām no vissvarīgākajām valodas prasmēm. Turklāt, valodas precizitāte parāda svešvalodas līmeņa lietpratību. Skolās būtu nepieciešams likt lielāku uzsvaru uz pareizu gramatikas un vārdu krājuma pielietošanu svešvalodas apguvē visos vecuma posmos. Darba autors veica 12 nedēļu ilgu gadījuma izpēti Rīgas 64. vidusskolā. Pētījumā piedalījās 17 skolēni, kuri veidoja PowToon video ar teksta ierunāšanas funkciju valodas precizitātes pilnveidei. Tika izmantotas tādas datu vākšanas metodes kā fokusgrupas intervija, vērtēšanas lapas un anketa. Izanalizējot skolēnu darbus, tika secināts, ka, kaut arī daži skolēni iespējams uzlaboja valodas precizitāti, kopējie r…
Design and performance evaluation of a high power density EMI filter for PWM inverter-fed induction motor drives
2015
This paper presents the design of an electromagnetic interference (EMI) filter for a low voltage high current induction motor drives supplied by DC power grids, such as those used in several vehicle applications. In order to effectively design the EMI filter a suitable Common Mode/Differential Mode (CM/DM) separation technique has been used. In consideration of the high operating currents, a software based separation technique using time domain measurements has been applied. The proposed technique allows the CM and DM sections of the EMI filter to be properly selected in a more economical way, i.e. without the need of dedicated hardware or costly radio frequency (RF) instrumentation. The de…
Harder, Better, Faster, Stronger? The Relationship between Cognitive Task Demands in Video Games and Recovery Experiences
2019
Research has repeatedly demonstrated that the use of interactive media is associated with recovery experiences, suggesting that engaging with media can help people to alleviate stress and restore mental and physical resources. Video games, in particular, have been shown to fulfil various aspects of recovery, not least due to their ability to elicit feelings of mastery and control. However, little is known about the role of cognitive task demand (i.e., the amount of cognitive effort a task requires) in that process. Toward this end, our study aimed to investigate how cognitive task demand during gameplay affects users’ recovery experiences. Results of a laboratory experiment suggest that dif…
PROCESSI DI TRADUZIONE E SCRITTURA ELEMENTARE NELLA LINGUA STRANIERA TEDESCA
2014
L’articolo presenta i primi risultati di una ricerca qualitativa sulla scrittura in lingua straniera con l’aiuto di Google Traduttore. In questo lavoro prendiamo in esame i processi, cioè le forme di costruzione delle strutture verbali e discorsive nel mentre si articolano dal vivo durante la costruzione di una traduzione di sito web di carattere turistico. Lo studio si è svolto nell’anno accademico 2013/2014 e si è basato sulla videoregistrazione di circa 12 ore di lavoro in gruppi di 4 persone mentre progettano, lavorano e producono la stesura di parti della homepage in lingua tedesca di un sito turistico. Il lavoro mette in risalto sia le potenzialità che i limiti dell’utilizzo delle ris…

Resonancia mágnetica pélvica dinámica versus videodefecografía en el estudio del síndrome de defecación obstructiva
2015
Título: Resonancia magnética pélvica dinámica versus videodefecografía en el estudio del síndrome de defecación obstructiva. Introducción: El síndrome de defecación obstructiva (SDO) designa la dificultad de evacuar satisfactoriamente el recto durante la defecación. Una herramienta esencial para definirlo son los estudios dinámicos de imagen como la videodefecografía (VD) y la resonancia magnética pélvica dinámica (RMPD). La prueba complementaria para el estudio del SDO más empleada actualmente es la VD introducida en los años 60 Burhenne et al. La RMPD supone una moderna alternativa con múltiples ventajas potenciales para el estudio del SDO. El objetivo del trabajo es realizar un estudio p…
A Non-linear Diffeomorphic Framework for Prostate Multimodal Registration
2011
International audience; This paper presents a novel method for non-rigid registration of prostate multimodal images based on a nonlinear framework. The parametric estimation of the non-linear diffeomorphism between the 2D fixed and moving images has its basis in solving a set of non-linear equations of thin-plate splines. The regularized bending energy of the thin-plate splines along with the localization error of established correspondences is jointly minimized with the fixed and transformed image difference; where, the transformed image is represented by the set of non-linear equations defined over the moving image. The traditional thin-plate splines with established correspondences may p…
“How Did Child of Light Save Me?” Engagement with a Children’s Multimodal Game Narrative as Adult Play and Self-Therapy
2021
This chapter investigates the online reception of the Canadian video game Child of Light (Ubisoft, Child of Light. Montreal: Ubisoft Studios. Video Game, 2014) as a space of encounter between imaginary childhoods and experienced adulthoods. Child of Light is a well-selling video game involving a conventional fairy-tale narrative about a young princess Aurora battling against darkness with a party of companions. The game contains narrative elements typical of children’s stories but has been popular among adult players. The focus of this chapter is on a specific case study: an adult male professional game reviewer and his publicly shared online life narrative, in which he discusses his real-l…
Reliability and validity of the Toronto Structured Interview for Alexithymia in a mixed clinical and nonclinical sample from Italy
2011
The reliability and validity of the Toronto Structured Interview for Alexithymia (TSIA) have been demonstrated in previous studies with English-speaking community and psychiatric samples and a German-speaking psychiatric sample. The aim of this study was to evaluate the psychometric properties of the TSIA in a mixed clinical and nonclinical sample from Italy. The original English version of the TSIA was translated into Italian and administered, along with the 20-item Toronto Alexithymia Scale (TAS-20), to 80 healthy subjects, 69 medical outpatients, and 62 psychiatric outpatients. Eighty-one videotaped interviews were used for assessing the interrater reliability. Confirmatory factor analys…
