The kinetics of defect accumulation under irradiation: many-particle effects
1993
The kinetics of Frenkel defect accumulation under permanent particle source (irradiation) is discussed with special emphasis on many-particle effects. Defect accumulation is restricted by their diffusion and annihilation, A + B → 0, if the relative distance is less than the critical distance r0. A novel formalism of many-point particle densities based on Kirkwood's superposition approximation is developed to take into account aggregation of similar defects (A−A, B−B). The dependence of the saturation concentration after a prolonged irradiation upon spatial dimension ( = 1, 2, 3), defect mobility and the initial correlation within geminate pairs is analyzed. It is shown that the defect conce…
Hamilton–Jacobi semi-groups in infinite dimensional spaces
2006
AbstractLet (X,ρ) be a Polish space endowed with a probability measure μ. Assume that we can do Malliavin Calculus on (X,μ). Let d:X×X→[0,+∞] be a pseudo-distance. Consider QtF(x)=infy∈X{F(y)+d2(x,y)/2t}. We shall prove that QtF satisfies the Hamilton–Jacobi inequality under suitable conditions. This result will be applied to establish transportation cost inequalities on path groups and loop groups in the spirit of Bobkov, Gentil and Ledoux.
Transportation-cost inequality on path spaces with uniform distance
2008
Abstract Let M be a complete Riemannian manifold and μ the distribution of the diffusion process generated by 1 2 ( Δ + Z ) where Z is a C 1 -vector field. When Ric − ∇ Z is bounded below and Z has, for instance, linear growth, the transportation-cost inequality with respect to the uniform distance is established for μ on the path space over M . A simple example is given to show the optimality of the condition.
Distances kredītu izplatība Latvijā
2018
Bakalaura darba mērķis ir, pamatojoties uz distances kredītu izplatības un piemērošanas izpēti, izstrādāt priekšlikumus to negatīvo seku novēršanai. Darbā tiek pētīta distances kredītu izpaltība laika posmā no 2007. līdz 2017.gadam, īpaši pētot tieši laika posmu no 2016. līdz 2017. gadam, tādā veidā padziļināti izpētot tieši šī brīža situāciju distances kreditēšanas nozarē Latvijā. Bakalaura darbā sniegta distances kredītu izsniedzēju analīze, kā arī distances kreditēšanas attīstību ietekmējošie faktori. Tāpat arī doti secinājumi par distances kredīta tirgus attīstību Latvijā un izvirzīti priekšlikumi problēmu risināšanai.
Aktivitātes tālmācības vidusskolas 10. klases angļu valodas stundās pašvadītas mācīšanās pilnveidošanai
2021
Darba autore nesen sāka strādāt par angļu valodas skolotāju tālmācības vidusskolā. Pētījuma mērķis bija pielietot praksē uzdevumus, kas pilnveidotu pašvadītas mācīšanās prasmes tālmācības skolas 10. klases angļu valodas stundās. Pētījuma bāze bija 49 tālmācības skolēni, kuriem bija jāveic ikmēneša uzdevumos iestrādāts pašvērtējums un atgriezeniskā saite, attiecīgi tika veikta kvalitatīva datu vākšana un analīze. Tika apzināts, kādas pašvadītas mācīšanās prasmes audzēkņi ir apguvuši un kādi izaicinājumi joprojām pastāv. Rezultātā tika ieskicētas turpmāk veicamās aktivitātes pašvadītas mācīšanās sekmēšanai. Pētījuma atziņas var izmantot skolotāji, kuri saskaras ar tiešsaistes mācību izaicināj…
Distribution of maternity units and spatial access to specialised care for women delivering before 32 weeks of gestation in Europe
2010
Contains fulltext : 88841.pdf (Publisher’s version ) (Closed access) Survival and quality of life are improved for very preterm babies when delivery occurs in a maternity unit with on-site neonatal intensive care (level III unit). We investigated the impact of distance on the probability of delivering in such a unit for births before 32 weeks of gestation from 9 European regions with diverse perinatal health systems (the MOSAIC cohort). We analysed distances between women's homes, and the nearest level III in population quartiles, adjusting for maternal and pregnancy characteristics. Living farther away from a level III reduced access to specialised care everywhere; in some regions women re…
Peer assessment based assignment to enhance interactions in online learning groups
2015
In this paper, we report on the findings from our PhD work on how peer assessment based assignment method can enhance interaction in online learning groups. The method is explored and tried out on the research methods course on the Bachelor of Commerce Programme which is run in distance learning mode at Makerere University. Based on the idea that learning groups can enhance effective learning in online learning environments, we used the affordance eLearning framework to design the peer assessment based assignment task and then qualitative methods collect and report on data. The results reveal that there was increased interaction through peer feedback. Students were motivated because of the …
Enseñanza mutua en línea: una investigación piloto realizada con los estudiantes universitarios
2023
In academic year 2020-2021, a pilot research was carried out on distance peer teaching, which was hypothesized as effective tool to reduce some of the negative effects that distance teaching, imposed by the Coronavirus pandemic, caused among students enrolled in the first year of the three-year degree course in Educational Sciences at the University of Palermo during the academic year 2019-2020. Nineteen students attending the second year of this course, after having participated in a specific training activity (15 h), from March to June 2021 helped 35 fellow students to advance their careers by catching up as many first-year exams as possible through distance support. In July 2021, the gro…
Percezione di efficacia dei docenti universitari e personalizzazione del processo di insegnamento-apprendimento con la DaD
2020
Per rispettare le misure di distanziamento imposte dal COVID 19, le Università hanno dovuto adottare la didattica a distanza (DaD). L’occasione è stata propizia per cercare di personalizzare il processo di insegnamento-apprendimento, vale a dire per centrare meglio la formazione erogata dalle università sulle esigenze dei singoli studenti. L’attuazione dei principi della didattica personalizzata ha richiesto un impegno non indifferente ai docenti che vi si sono cimentati. È stato ipotizzato che la percezione della propria capacità di personalizzare la formazione degli studenti con il supporto delle tecnologie dell’informazione e della comunicazione, influisse sull’efficacia didattica dei do…
Multivariate equivalence tests for use in pharmaceutical development.
2014
Statistical equivalence analyses are well-established parts of many studies in the biomedical sciences. Also in pharmaceutical development and manufacturing equivalence testing methods are required in order to statistically establish similarities between machines, process components, or complete processes. This article presents a choice of multivariate equivalence testing procedures for normally distributed data as generalizations of existing univariate methods. In all derived methods, variability is interpreted as nuisance parameter. The use of the proposed methods in pharmaceutical development is demonstrated with a comparative analysis of dissolution profiles.
