Novel qutrit circuit design for multiplexer, De-multiplexer, and decoder

2022

AbstractDesigning conventional circuits present many challenges, including minimizing internal power dissipation. An approach to overcoming this problem is utilizing quantum technology, which has attracted significant attention as an alternative to Nanoscale CMOS technology. The reduction of energy dissipation makes quantum circuits an up-and-coming emerging technology. Ternary logic can potentially diminish the quantum circuit width, which is currently a limitation in quantum technologies. Using qutrit instead of qubit could play an essential role in the future of quantum computing. First, we propose two approaches for quantum ternary decoder circuit in this context. Then, we propose a qua…

Transport and extraction of radioactive ions stopped in superfluid helium

2003

A new approach to convert a high energy beam to a low energy one, which is essential for the next generation radioactive ion beam facilities, has been proposed and tested at Jyvaskyla, Finland. An open Ra-223 alpha-decay-recoil source has been used to produce radioactive ions in superfluid helium. The alpha spectra demonstrate that the recoiling Rn-219 ions have been extracted out of liquid helium. This first observation of the extraction of heavy positive ions across the superfluid helium surface was possible thanks to the high sensitivity of radioactivity detection. An efficiency of 36% was obtained for the ion extraction out of liquid helium. (C) 2003 Elsevier Science B.V. All rights res…

A Stochastic Decision Process Model for Optimization of Railway and Tramway Track Maintenance by means of Image Processing Technique

2013

One of the key targets for an efficient transport network management is the search for proper maintenance policies to guarantee acceptable safety and quality standards in the travel and to optimize available resource allocation. Methodologically, the proposed model presented in this paper uses the stochastic dynamic programming and in particular Markov decision processes applied to the rail wear conditions for the railway and tramway network. By performing the integrated analysis of the classes of variables which characterize the rail quality (in terms of safety), the proposed mathematical approach allows to find the solutions to the decision-making process related to the probability of det…

Automated Railway Signs Detection. Preliminary Results

2019

Abstract Nowadays safety in railways is mostly achieved by automated system technologies such as ERTMS/ETCS. Nevertheless, on local railways (suburban and regional lines) several tasks still depend on the choices and actions of a human crew. With the aim to improve safety in such type of railways, this research proposes a system for the automatic detection and recognition of railway signs by means of the digital image processing technique. First field applications, carried out on the Italian railway network, show that the proposed system is very accurate (the percentage of correctly detected railway signs is about 97%), even at high train speeds.

5 – 7 gadīgu bērnu lasīt-rakstīt apguves veicināšana pedagoģiskajā procesā pirmsskolā

2021

Bakalaura darba temats ir ”5 – 7 gadīgu bērnu lasīt-rakstīt apguves veicināšana pedagoģiskajā procesā pirmsskolā.” Darba autore - Lelde Žīgure. Pētījuma mērķis: teorētiski un praktiski izzināt metodes un paņēmienus 5 – 7 gadīgu bērnu lasīt-rakstīt prasmju apguves sekmēšanā. Pētījumā izvirzītais uzdevums raksturo mērķa sasniegšanas un hipotēzes pārbaudes procesu. Hipotētiski tiek pieņemts, ka bērna netiešā un tiešā lasīt-rakstīt prasme ir saistīta ar bērna iespējām izvēlēties sev nozīmīgu darbību no piedāvātiem rotaļnodarbības paņēmieniem un pašizteikšanās radošā pedagoģiskajā vidē. Bakalaura darbu veido ievads, divas galvenās nodaļas ar apakšnodaļām, ieteikumi un secinājumi par teorētiskās …

Baveno VII – Renewing consensus in portal hypertension

2022

To expand on the work of previous meetings, a virtual Baveno VII workshop was organised for October 2021. Among patients with compensated cirrhosis or compensated advanced chronic liver disease (cACLD – defined at the Baveno VI conference), the presence or absence of clinically significant portal hypertension (CSPH) is associated with differing outcomes, including risk of death, and different diagnostic and therapeutic needs. Accordingly, the Baveno VII workshop was entitled “Personalized Care for Portal Hypertension”. The main fields of discussion were the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard, the use of non-invasive tools for the …

Skala Niesprawności Neurologicznej Szpitala Guy jako istotne narzędzie do oceny objawów występujących u osób z SM

2017

Skala Niesprawności Neurologicznej Szpitala Guy (GNDS, The Guy’s Neurological Disability Scale) jest istotnym narzędziem służącym do pomiaru niepełnosprawności u osób ze stwardnieniem rozsianym. Służy ona do określenia poziomu funkcjonowania w dwunastu ważnych obszarach. Celem obecnych badań było opracowanie polskiej wersji językowej skali GNDS i sprawdzenie jej trafności, rzetelności oraz przydatności do oceny niepełnosprawności występującej u osób ze stwardnieniem rozsianym. Grupę badaną stanowiło 175. pacjentów z rozpoznaniem stwardnienia rozsianego. W badaniu wykorzystano Rozszerzoną Skalę Niewydolności Ruchowej – EDSS, Skalę Niesprawności Neurologicznej Szpitala Guy – GNDS, Skalę Akcep…

Italian Adaptation of the "Autonomy and Relatedness Coding System

2013

The study examined the applicability of the observational technique developed by Allen and colleagues (Allen, Hauser, Bell, & O’Connor, 1994; Allen, Hauser, et al., 2003) to investigate the issues of autonomy and relatedness in parent-adolescent relationship in the Italian context. Thirty-five mother-adolescent dyads participated to a task in which they discussed a family issue about which they disagree. Adolescents were also administered a self-report measure assessing their relationship with mothers. Mothers reported significantly higher levels of promoting and inhibiting autonomy, and promoting relatedness behaviors than their children. Results also suggested a partial behavioral rec…
