Stochastic seismic analysis of MDOF structures with viscous damper devices
2009
Fluid damper devices in civil structures such as buildings or bridges are commonly used as energy absorbers for seismic protection. The problem in the response analysis of structures with filled dampers mainly consists in the fact that, due to the strongly nonlinear behavior of such equipments, the response spectrum technique fails. In this paper by using the concept of power spectral density function compatible with the elastic response spectrum and the stochastic linearization technique, the equivalent damping ratio is obtained. It is shown that once the system is linearized results obtained by Monte Carlo simulation and those obtained by stochastic analysis are in good agreement. Respons…
Defamiliarizing Blackness and Whiteness in Gloria Naylor’s "Linden Hills"
2018
Gloria Naylor defamiliarizes in Linden Hills (1985) both white and non-white racial categories, in this case blackness and whiteness, both of which emerge as largely performable identities. The defamiliarization of blackness is fairly direct, unfolding mostly through the predominantly negative portrayal of Linden Hills residents and the male line of the Nedeed dynasty, especially Luther Nedeed IV. The defamiliarization of whiteness is mostly indirect, taking place primarily through the exposure of Linden Hills residents’ imitation of whiteness, in particular, the pursuit of what is presented as the negative paradigm of the white materialistic success and the disastrous consequences that ste…
OCTA atlīdzību apjoma modelēšana, lietojot vispārināto lineāro modeli
2017
Darbs veltīts obligātās civiltiesiskās transportlīdzekļu apdrošināšanas (OCTA) atlīdzību modelēšanai. Modeļu klase, ko izvēlēts lietot, ir vispārinātais lineārais modelis (GLM), kas praksē tiek bieži lietots apdrošināšanas atlīdzību modelēšanai. Darbā aprakstīti vispārinātā lineārā modeļa teorijas pamati un modeļa precizitātes novērtēšanas mēri. Aplūkotas dažādas modeļa parametru novērtēšanas un faktoru atlases metodes, no iegūtajiem modeļiem izvēlēts modelis ar labāko pielāgošanas kvalitāti un precīzāko prognozēšanas spēju. Visbiežāk lietotās metodes - iteratīvā mazāko kvadrātu metode parametru novērtēšanai un soļu regresija faktoru atlasei tika salīdzinātas ar lasso un elastīgo tīklu regu…
Challenging Transmission Modes of Teaching in Science Classrooms : Enhancing Learner-Centredness through Dialogicity
2017
There is an ongoing reform towards more inquiry-based teaching in school curriculum policy in South Africa. Reform towards more inquiry-based approaches is already integrated in pre-service teacher education programmes. As inquiry-based approaches have been gaining momentum worldwide, there is an increasing concern that dialogic interaction in classroom communication is being neglected. This is especially within teacher-orchestrated classroom interactions that should foster greater learner centredness and thus authentic scientific inquiry. In learner-centred teaching approaches, student contributions should be explicitly taken into account as part of classroom interactions in science. Learn…
REVERSE ELECTRODIALYSIS FOR POWER PRODUCTION FROM OILFIELD WASTEWATERS
2022
Produced waters (PWs) are wastewaters generated by crude-oil extraction processes. They can present very different characteristics depending on the field location and production process. Dispersed oil, dissolved organics and solid particles are usually the main components. Moreover, PWs can contain a very high quantity of dissolved salts 1, with a total dissolved solid (TDS) concentration up to 300 g/L. Each barrel of extracted oil requires the simultaneous extraction of 3 barrels of produced water2 on average. PWs are often discharged into the sea, or sent in evaporation ponds thus leading to a dramatic environment impact3. Reinjection in the extraction well is currently the most common an…
Effect of Boron Doping on the Wear Behavior of the Growth and Nucleation Surfaces of Micro- and Nanocrystalline Diamond Films
2016
B-doped diamond has become the ultimate material for applications in the field of microelectromechanical systems (MEMS), which require both highly wear resistant and electrically conductive diamond films and microstructures. Despite the extensive research of the tribological properties of undoped diamond, to date there is very limited knowledge of the wear properties of highly B-doped diamond. Therefore, in this work a comprehensive investigation of the wear behavior of highly B-doped diamond is presented. Reciprocating sliding tests are performed on micro- and nanocrystalline diamond (MCD, NCD) films with varying B-doping levels and thicknesses. We demonstrate a linear dependency of the we…
The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …
2021
The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…

Abating inequalities? : Job quality at the intersection of class and gender in Finland 1977–2013
2016
Globalization with its many side-effects on working life is seen to pose accentuated risks especially for women and low skilled workers – resulting in increasing polarization of job quality. In contrast to “universal theories”, institutional theories claim changes in work life might vary according to the institutional and cultural frameworks which mediate the global pressures of change. This study analyses job quality trends in Finland at the intersection of class and gender. The results, based on the Finnish Quality of Work Life survey (1977–2013), find no clear evidence of polarization. In line with the institutional theory’s prediction of a low risk of polarization in coordinated and in…
Zarządzanie strategiczne akademickim kształceniem ekonomistów w kontekście oczekiwań studentów i wymagań zmieniającego się rynku pracy
2020
Kultura i edukacja ekonomiczna były tematem jednej z sesji panelowych X Kongresu Ekonomistów Polskich, który odbył się w listopadzie 2019 r. W nowej klasyfikacji dziedzin i dyscyplin naukowych wprowadzonej w Polsce w 2018 r. nie uwzględniono kategorii nauki ekonomiczne. Rodzi to pytanie o identyfikację kierunków i profili kształcenia ekonomicznego na poziomie wyższym, wpływając zarazem na kształtowanie oferty edukacyjnej uczelni. Kierunki ekonomiczne nadal cieszą się dużą popularnością, ale coraz częściej poddawany jest krytyce zakres i sposób kształcenia ekonomistów. Studenci domagają się wprowadzenia pluralizmu w naukach ekonomicznych i zmniejszenia stopnia ich matematyzacji, „odświeżenia…
