Noen aspekter ved implementasjon og ytelse for kryptosystemer basert på elliptiske kurver
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad I den senere tid har kryptografi basert på elliptiske kurver blitt tatt i bruk i økende grad. De fleste av dagens implementasjoner baserer seg på kurver på Weierstrassform, y2z + a1xyz + a3yz2 = x3 + a2x2z + a4xz2 + a6z3. Hesseform av elliptiske kurver, x3 +y3 +z3 = Dxyz, har en del egenskaper som gjør den velegnet til bruk i kryptografi. Basert på antall grunnoperasjoner som utføres i algoritmene, bør Hesseform være bedre enn Weierstrassform ytelsesmessig. I dette arbeidet utfører vi en del hastighetstester av punktoperasjoner på kurver på kort Weierstrass- og Hesseform. Vi har implementert algoritm…
Lukemisen ja aritmetiikan sujuvuuden kehittyminen toisen koululuokan aikana
2014
Tutkimuksessa tarkasteltiin lukemisen ja aritmetiikan sujuvuutta ja niiden kehitystä toisen koululuokan aikana kolmena ajankohtana (lukukauden alussa, keskellä ja lopussa). Lukemisen sujuvuuden kehitys oli edistyvää niin sujuvilla kuin sujumattomillakin lukijoilla. Sen sijaan yhteen- ja vähennyslaskutaidon sujuvuudessa ei tapahtunut juurikaan kehitystä sujumattomilla laskijoilla, toisin kuin sujuvilla laskijoilla, joiden kehitys oli edistyvää lukukauden aikana. Tulokset tukevat oletusta aritmetiikan taitojen kehityksen Matteusvaikutuksesta, eli siitä, että lähtötasoltaan aritmetiikassa sujumattomien kehitys jää jälkeen lähtötasoltaan sujuvien laskijoiden kehityksestä. Lukutaidon taso ei sen…

Prematurity and overlap between reading and arithmetic: The cognitive mechanisms behind the association
2019
It is well-known that very preterm children perform at lower levels than full-term children in reading and arithmetic at school. Whether the lower performance levels of preterm children in these two separate domains have the same or different origins, however, is not clear. The present study examined the extent to which prematurity is associated with the overlap (i.e., common variance) of reading and arithmetic among Finnish school beginners. We also examined the extent to which the association of prematurity with the overlap between reading and arithmetic is due to different prereading skills, basic number skills, and general cognitive abilities. The participants (age 6-7) consisted of 193…

A meta-analysis of the relation between RAN and mathematics.
2017
Several studies have shown that rapid automatized naming (RAN) is a significant predictor of mathematics, but the nature of their relationship remains elusive. Thus, the purpose of this meta-analysis was to estimate the size of their relationship and determine the conditions under which they correlate. We used a random-effects model analysis of data from 38 studies (33 unique samples, 151 correlations, 7,135 participants) to examine the size of the RAN–mathematics relationship and the role of different moderators (i.e., math measure and variable, type of RAN task, math age, study design, and sample characteristics). The results showed a significant correlation between RAN and mathematics (r…
Il problem solving aritmetico: analisi dei processi cognitivi e metacognitivi e illustrazione del software "Risolvere problemi aritmetici"
2010
Il presente contributo esamina la letteratura relativa al problem solving matematico ed illustra uno strumento multimediale per la soluzione dei problemi aritmetici in bambini del secondo ciclo della scuola primaria e in bambini che presentano difficoltà in tale area. Il software presenta sia un modulo test, in cui vengono presentati problemi aritmetici di livello di difficoltà crescente, che un modulo di training. Il training è stato elaborato in base alle più recenti ricerche nell’area del problem solving matematico e prevede attività sulla comprensione, rappresentazione, categorizzazione e pianificazione del problema. Il training prevede inoltre particolari attività che stimolano l’uso d…

Estructura del vers i variació lingüística en textos antics: els poemes d’Ausiàs March
2022
L’objectiu d’aquesta presentació és mostrar que diversos aspectes de la mètrica com el recompte sil·làbic, la rima i els patrons rítmics, ens poden ajudar a extraure informació sobre la variació lingüística d’altres èpoques. El treball analitza algunes variants formals presents en els poemes d’Ausiàs March (1397–1459) que serveixen per a satisfer els requeriments mètrics del vers. Pel que fa al recompte de síl·labes, ens centrarem en el tractament doble, com a hiats o com a diftongs, de les seqüències vocàliques decreixents: tot i l’aclaparadora majoria de formes amb hiat, les dades deixen entreveure que en aquell temps ja actuaven algunes de les restriccions vigents en l’actualitat, com la…
Ability to Measure and Count in Aleksis Kivi’s Seven Brothers
2021
The illiterate brothers’ elementary ability to measure and count fluently is a striking feature in the Finnish author Aleksis Kivi’s Seven Brothers (Seitsemän veljestä, 1870), a novel that was published before the metric system was introduced in Finland. The seven main characters describe their everyday life and environment and make work- related decisions using numbers, amounts, and measures of distance, area, volume, and weight without hesitation. They are also familiar with some elementary calculations. At the same time, their inability to read arouses desperate anguish in them. I analyze the ways the brothers use numbers and measurements, and the importance of these skills in their life…
