Novel high-performance QCA Fredkin gate and designing scalable QCA binary to gray and vice versa

2022

AbstractIn the design of digital logic circuits, QCA technology is an excellent alternative to CMOS technology. Its advantages over CMOS include low power consumption, fast circuit switching, and nanoscale design. Circuits that convert data between different formats are code converters. Code converters have an essential role in high-performance computing and signal processing. In this paper, first, we proposed a novel QCA structure for the quantum reversible Fredkin gate. Second, we proposed 4-bit and 8-bit QCA binary-to-gray converter and vice versa. For the second proposal, both reversible and irreversible structures are suggested. The proposed structures are scalable up to N bits. To cha…

Short-time non-work-related computing and creative performance

2014

It has been argued that non-work-related computing (NWRC) takes time away from work and, hence, decreases work productivity. On the other hand, it has also been claimed that short-time non-work-related computing (STNWRC) (a maximum of 15 minutes), has a positive impact on work productivity, including relief from boredom, higher creativity, and the underlying recovery mechanisms. To examine the impact of STNWRC on creative performance, we draw on Fredrickson's broaden-and-build theory, the concept of recovery with mental well-being and low cognitive effort. A 2 × 2 factorial experiment with 40 subjects was conducted. The results indicate that STNWRC has a positive effect on creative performa…

Suuret teknologiat : miten teknologiaa kuvattiin Helsingin Sanomien uutisoinnissa ja kirjoittelussa vuosina 1889-1930

2016

Tutkimuksessa tarkastellaan teknologian historiaa 1900-luvun vaihteen Suo-messa. Päälähteenä toimii vuodesta 1889 lähtien julkaistu sanomalehti, Helsingin Sanomat. Tutkimuksessa selvitetään aineistolähtöisen grounded theory -menetelmän avulla niitä piirteitä ja tapoja, joilla uusia yhteiskuntaan merkittävästi vaikuttaneita teknologioita kuvattiin. Suuria teknologioita, joilla tarkoitetaan merkittäviä yhteiskuntaan juurtuneita teknologioita, alettiin kuvata ajankohtaisemmin ja niitä yhteiskuntaan liittäen 1930 – lukua lähestyttäessä. Tämä oli seurausta teknologian yleistymisestä ja aikaisempaa merkittävämmästä näkyvyydestä yhteiskunnassa. Teknologian kuvaaminen muuttui selkeimmin auton kohda…

The emission reduction potentials of First Generation Electric Aircraft (FGEA) in Finland

2020

Under the looming climate crisis, aviation needs to find new solutions to cut its greenhouse gas emissions. One pathway towards zero emissions is the use of electric aircraft. While current battery technology will not allow for medium and long-haul flights at full capacity, on short-haul routes First Generation Electric Aircraft (FGEA) could play a significant role in the near future. Current FGEA under development could carry 9–19 passengers on distances of 400–1046 km by 2025. This study focuses on the emissions reduction potentials of FGEA in Finland. It compares the carbon dioxide equivalent (CO2-eq) emissions and real travel times (RTT) from door-to-door of FGEA on 47 routes with exist…

On the (In)Security of 1090ES and UAT978 Mobile Cockpit Information Systems : An Attacker Perspective on the Availability of ADS-B Safety- and Missio…

2022

Automatic dependent surveillance-broadcast (ADS-B) is a key air surveillance technology and a critical component of next-generation air transportation systems. It significantly simplifies aircraft surveillance technology and improves airborne traffic situational awareness. Many types of mobile cockpit information systems (MCISs) are based on ADS-B technology. MCIS gives pilots the flight and traffic-related information they need. MCIS has two parts: an ADS-B transceiver and an electronic flight bag (EFB) application. The ADS-B transceivers transmit and receive the ADS-B radio signals while the EFB applications hosted on mobile phones display the data. Because they are cheap, lightweight, an…

Uusliberaalia sosiaalipolitiikkaa? : uusliberaalin sosiaalipolitiikan suosio eduskuntavaaliehdokkaiden joukossa Ylen vaalikoneen perusteella vuoden 2…

2014

Tausta ja tavoite: Tämä tutkimus pyrkii selvittämään vuoden 2011 eduskuntavaalien kansanedustajaehdokkaiden vaalikonevastausten perusteella, kuinka suosittuja uusliberalistiset sosiaalipolitiikan toteuttamistavat ovat ehdokkaiden keskuudessa. Kaikkien ehdokkaiden ja edustajaksi päässeiden vertailut tuottavat tietoa myös eduskunnan uusliberaaliudesta. Toteutustapa: Vuonna 2011 valituista kansanedustajista 194/200 kansanedustajasta vastasi Ylen vaalikoneeseen ennen valituksi tulemistaan. Lisäksi yli tuhat muuta ehdokasta, jotka eivät tulleet valituiksi, vastasivat vaalikoneeseen. Ylen vaalikoneen data on julkaistu internetissä avoimena datana Creative Commons ­-Tlisenssillä. Tutkimuksessa vaa…

Tablet-Supported Self-Assessment in a Class for Students with Intellectual Disability

2023

Self-assessment has been shown to have positive effects on students’ self-regulated learning strategies and academic achievement. However, self-assessment and self-assessment instruction are under-researched areas among students with intellectual disability. This data-driven qualitative study aimed at examining the self-assessment expressions students with intellectual disability documented in their learning diaries and how the teacher and teaching assistants used video recordings to facilitate students’ self-assessments in one Finnish special needs education class. The naturally occurring research data consisted of both students’ tablet-based learning diaries (N = 6) and video recordings o…
