With great power comes great responsibilities – Examining platform-based mechanisms and institutional trust in rideshare services
2023
From the perspective of female passengers, much remains unknown about institutional or platform trust and the sharing economy. The present study was conducted in an emerging economy context to comprehend the significance of institutional trust. The study aimed to develop a dynamic theoretical model incorporating the perceived effectiveness of platform-based institutional structures (PEPIS) as a dependent variable in sharing economy platforms, examine the antecedents of PEPIS and determine how PEPIS affects female passengers' trust in the institution or platform. Different strata of female passengers were targeted using a quota-cum-purposive sampling method. In total, 413 useable responses t…
Operacionālā riska zaudējumu statistiskā modelēšana, izmantojot Beijesa statistikas metodes
2022
Bakalaura darbā tiek apskatīta operacionālā riska zaudējumu statistiskā modelēšana, izmantojot Beijesa metodi. Darbā tiek aprakstīta standarta zaudējumu sadalījuma pieeja, Beijesa metode, saistītie apriorie sadalījumi, kā arī riskam pakļautās vērtības novērtēšana gan ar Montekarlo simulāciju, gan ar aproksimācijas formulu palīdzību. Praktiskajā daļā tiek pielietota Beijesa metode, lai novērtētu parametrus simulētiem datiem trīs darbā minētajiem saistītajiem sadalījumiem. Kā arī tiek aplūkots datu piemērs, kur apriorie parametri tiek novērtēti ar Beijesa metodi, un gan ar Montekarlo simulāciju, gan aproksimācijas formulu palīdzību tiek aprēķināta riskam pakļautā vērtība. Rezultāti tiek salīd…

On the theoretical–numerical study of the HEXCALIBER mock-up thermo-mechanical behaviour
2010
Abstract Within the framework of the R&D activities promoted by European Fusion Development Agreement on the Helium-Cooled Pebble Bed Test Blanket Module to be irradiated in ITER, ENEA Brasimone and the Department of Nuclear Engineering of the University of Palermo (DIN) performed intense research activities on the modelling of the thermo-mechanical behaviour of both beryllium and lithiated ceramics pebble beds, that are envisaged to be used, respectively, as neutron multiplier and tritium breeder. In particular, the DIN developed a thermo-mechanical constitutive model for these pebble beds to be validated against the HEXCALIBER mock-up test campaign, carried out at the ENEA HE-FUS3 facilit…
Équivalents finnois du futur morphologique français : étude contrastive de dix nouvelles de Guy de Maupassant et de leurs traductions finnoises
2014
Tiivistelmä – Abstract Tutkielman tarkoituksena on selvittää, kuinka ranskan kielen morfologinen futuurirakenne esitetään suomenkielisissä käännösteksteissä. Kontrastiivisen asetelman tekee mielenkiintoiseksi se, että morfologinen futuuri puuttuu suomen kielestä kokonaan. Näin ollen kääntäjän on käytettävä muita keinoja futuurisen aspektin ilmaisuun. Tutkielman korpuksen ranskankielinen osa koostuu kymmenestä Guy de Maupassantin vuosina 1881– 1890 ilmestyneestä novellista. Käännöskorpus sisältää kolmen kääntäjän, Reino Hakamiehen, Elina Hytösen ja Annikki Sunin, suomennoksia, jotka ovat ilmestyneet vuosina 1960–1983. Ranskankielinen korpus käsittää noin 36 668 sanaa, suomenkielinen noin 25 …
Evidence for mechanical and chemical alteration of iron-nickel meteorites on Mars: Process insights for Meridiani Planum
2011
The weathering of meteorites found on Mars involves chemical and physical processes that can provide clues to climate conditions at the location of their discovery. Beginning on sol 1961, the Opportunity rover encountered three large iron meteorites within a few hundred meters of each other. In order of discovery, these rocks have been assigned the unofficial names Block Island, Shelter Island, and Mackinac Island. Each rock presents a unique but complimentary set of features that increase our understanding of weathering processes at Meridiani Planum. Significant morphologic characteristics interpretable as weathering features include (1) a large pit in Block Island, lined with delicate iro…
New insights into the mineralogy and weathering of the Meridiani Planum meteorite, Mars
2011
– Meridiani Planum is the first officially recognized meteorite find on the surface of Mars. It was discovered at and named after the landing site of the Mars Exploration Rover Opportunity. Based on its composition, it was classified as a IAB complex iron meteorite. Mossbauer spectra obtained by Opportunity are dominated by kamacite (α-Fe-Ni) and exhibit a small contribution of ferric oxide. Several small features in the spectra have been neglected to date. To shed more light on these features, five iron meteorite specimens were investigated as analogs to Meridiani Planum with a laboratory Mossbauer setup. Measurements were performed on (1) their metallic bulk, (2) troilite (FeS) inclusions…
A nonlinear mixed model approach to predict energy expenditure from heart rate.
2021
Abstract Objective. Heart rate (HR) monitoring provides a convenient and inexpensive way to predict energy expenditure (EE) during physical activity. However, there is a lot of variation among individuals in the EE-HR relationship, which should be taken into account in predictions. The objective is to develop a model that allows the prediction of EE based on HR as accurately as possible and allows an improvement of the prediction using calibration measurements from the target individual. Approach. We propose a nonlinear (logistic) mixed model for EE and HR measurements and an approach to calibrate the model for a new person who does not belong to the dataset used to estimate the model. The …
