A Crystalline 1D Dynamic Covalent Polymer
2022
The synthesis of crystalline one-dimensional polymers provides a fundamental understanding about the structure??? property relationship in polymeric materials and allows the preparation of materials with enhanced thermal, mechanical, and conducting properties. However, the synthesis of crystalline one-dimensional polymers remains a challenge because polymers tend to adopt amorphous or semicrystalline phases. Herein, we report the synthesis of a crystalline one-dimensional polymer in solution by dynamic covalent chemistry. The structure of the polymer has been unambiguously confirmed by microcrystal electron diffraction that together with charge transport studies and theoretical calculations…
Augsti jonizētas pulsējošas plazmas magnetrono izputināšanas procesu izstrāde volframa oksīdu plāno kārtiņu iegūšanai
2015
Elektrohromie materiāli spēj mainīt krāsu, elektrohromajai šūnai pieliekot elektrisko spriegumu. Šī īpašība ir ar plašu pielietojumu klāstu, piemēram, ēku energoefektivitātes uzlabošana, taču tie ir dārgi un daudzās jomās pagaidām ekonomiski neizdevīgi. Volframa trioksīda (WO3) plānās kārtiņas ir viens no visvairāk pētītajiem elektrohromajiem materiāliem. Darba mērķis bija izstrādāt augsti jonizētas pulsējošas plazmas magnetronās izputināšanas (HiPIMS) procesu volframa oksīdu plāno kārtiņu iegūšanai un salīdzināt tās ar plānajām kārtiņām, kas iegūtas ar līdzstrāvas magnetrona izputināšanas (DCMS) metodi. Izputināšanas režīms ietekmē gan izputināšanas ātrumu, gan plāno kāriņu elektrohromās ī…
Ocena wiarygodności internetowych serwisów wybranych polskich wyższych uczelni niepublicznych
2019
Celem artykułu jest dokonanie i przedstawienie oceny wiarygodności internetowych serwisów wybranych polskich wyższych uczelni niepublicznych. Koncepcja, metody badań: Sięgając do definicji terminów związanych z pojęciem wiarygodność odniesiono je do serwisów internetowych. Na tej podstawie stworzono konceptualne ramy oceny wiarygodności dla takich serwisów. Ramy te posłużyły do oceny wiarygodności internetowych serwisów wybranych wyższych uczelni niepublicznych w Polsce z wykorzystaniem metody sondażowej i oryginalnego narzędzia. Ranking wiarygodności badanych serwisów internetowych utworzono wykorzystując metodę TOPSIS. Wyniki i wnioski: W artykule pokazano, że zestaw cech i kryteriów używ…
Developing a globalization competence assessment framework and its application to Finnish and Japanese higher education
2013
Nykyajan kansainvälistyvä maailma luo uusia vaatimuksia valmistuneille ja ammattilaisille tietojärjestelmätieteen (TJT) alalla. Monikulttuurisessa ja hajautetussa ympäristössä työskentelystä on tullut arkipäivää, joten tarvittava pätevyys kansainvälisessä ympäristössä työskentelyyn on edellytys. Tämänhetkinen TJT:n opetussuunnitelma ei kuitenkaan ota kansainvälistymisopetusta huomioon riittävässä määrin. Opiskelijoiden todenmukaisen pätevyyden määrittämiseksi on arvioitava varsinaista kompetenssia pelkän tiedon sijaan. Tämän työn tarkoituksena on vastata edellä mainittuihin haasteisiin rakentamalla viitekehys opettajien käyttöön kansainvälistymiseen tarvittavien kompetenssien määrittämiseks…
Movement Detection with Event-Based Cameras: Comparison with Frame-Based Cameras in Robot Object Tracking Using Powerlink Communication
2018
Event-based cameras are not common in industrial applications despite the fact that they can add multiple advantages for applications with moving objects. In comparison with frame-based cameras, the amount of generated data is very low while keeping the main information in the scene. For an industrial environment with interconnected systems, data reduction becomes very important to avoid network congestion and provide faster response time. However, the use of new sensors as event-based cameras is not common since they do not usually provide connectivity to industrial buses. This work develops a network node based on a Field Programmable Gate Array (FPGA), including data acquisition and trac…
Optimization of Delayed-State Kalman-Filter-based Algorithm via Differential Evolution for Sensorless Control of Induction Motors
2010
This paper proposes the employment of the differential evolution (DE) to offline optimize the covariance matrices of a new reduced delayed-state Kalman-filter (DSKF)-based algorithm which estimates the stator-flux linkage components, in the stationary reference frame, to realize sensorless control of induction motors (IMs). The DSKF-based algorithm uses the derivatives of the stator-flux components as mathematical model and the stator-voltage equations as observation model so that only a vector of four variables has to be offline optimized. Numerical results, carried out using a low-speed training test, show that the proposed DE-based approach is very promising and clearly outperforms a cla…
El Portfolio Europeo de las Lenguas (PEL): herramienta de evaluación de la composición escrita en español como lengua extranjera
2013
Introducción Esta tesis pretende dar respuesta a uno de los desafíos que enfrentan los profesores de lenguas segundas (L2): mejorar la calidad de la evaluación de la expresión escrita. Partimos de la base del Marco Común Europeo de Referencia para las Lenguas (MCER), publicado por el Consejo de Europa con la intención de orientar la enseñanza y evaluación de lenguas, y del Portfolio Europeo de las Lenguas (PEL), cuyo propósito es aplicar en el aula los principios del MCER. Nos preguntamos si el PEL, que ha sido ampliamente experimentado en Educación Primaria y Secundaria, puede ser también útil como herramienta de evaluación de la composición escrita en niveles universitarios con estudiante…
External Changes and R&I Inter-Organizational Network Dynamics: The Case of EU R&I Policy Change
2022
The paper seeks to understand in what way changes in EU innovation policy incentives affect the EU R&I inter-organizational network dynamics. In particular, the study’s empirical settings are the two innovative inter-organizational networks that connect knowledge actors financed through two EU Framework Programs: the 7th Framework Program (or FP7), and the 8th Framework Program, named HORIZON 2020 (or H2020). Using a dataset of more than 22,228 unique projects in FP7 and 22,153 in H2020, we constructed two collaboration networks. We apply network analysis as a research instrument to identify and measure the fundamental structural properties and evolutionary dynamics of whole networks. I…
"The whole is greater than the sum of the parts". Metaphors of inclusion and exclusion in the British and Italian Fascist Discourse of the 1930s
2016
The rationale behind this work lies in the current economic, political, and social turmoil and the crisis of modern democracies. Adopting a Cognitive Linguistics standpoint, the paper looks at metaphorical instantiations of nationalistic issues in the British and Italian Fascist press of the 1930s. More particularly, it explores what metaphors are employed in English and Italian to convey the notion of “totality” implied in the theory of totalitarianism. Furthermore, it investigates how metaphors contribute to the legitimation of inclusion and exclusion strategies which are at the basis of nationalism. Findings show the presence of universal conceptual framings across cultures such as PEOPL…
Robust Selective Stereo SLAM without Loop Closure and Bundle Adjustment
2013
This paper presents a novel stereo SLAM framework, where a robust loop chain matching scheme for tracking keypoints is combined with an effective frame selection strategy. The proposed approach, referred to as selective SLAM (SSLAM), relies on the observation that the error in the pose estimation propagates from the uncertainty of the three-dimensional points. This is higher for distant points, corresponding to matches with low temporal flow disparity in the images. Comparative results based on the reference KITTI evaluation framework show that SSLAM is effective and can be implemented efficiently, as it does not require any loop closure or bundle adjustment.
