Radzenes biomehānisko parametru izmaiņas pēc kroslinkinga pacientiem ar keratokonusu
2019
Ievads: Pateicoties mūsdienu tehnoloģijām iespējams noteikt radzenes biomehāniskos parametrus, kurus klīniski var pielietot daudziem mērķiem. Piemēram, tādējādi iespējams diagnosticēt radzenes ektātiskās slimības jau to agrīnajās stadijās, proti, pirms parādās klīniskie simptomi un izmaiņas topogrāfijā, tostarp uzraudzīt slimības gaitu, izvērtēt terapijas efektivitāti, kā arī izvairīties no keratektāzijas pēc refraktīvās ķirurģijas. Pētījuma mērķis: Noteikt radzenes biomehāniskos parametrus keratokonusa pacientiem pirms un pēc radzenes kolagēna-kroslinkinga (CXL) 12 mēnešu periodā, pamatojoties uz Corvis ST (OCULUS Optikgeräte GmbH, Vācija) ierīces datiem. Balstoties uz iegūtajiem datiem, i…
Economic policy uncertainty effects for forecasting future real economic activity
2018
Recently introduced measures for Economic Policy Uncertainty (EPU) included in the data from 1997 - 2016 have a role in forecasting out-of-sample values for the future real economic activity for both the euro area and the UK economies. The inclusion of EPU measures, either for the US, the UK or for overall European economies, improves the forecasting ability of models based on standard financial market information, especially for the period before the 2008 global crisis. However, during and after the crisis period, the slope of the yield curve and excess stock market returns improves the out-of-sample forecast performance the most compared to an AR-benchmark model. Hence, the EPU informatio…
Application of selected supervised classification methods to bank marketing campaign
2016
Supervised classification covers a number of data mining methods based on training data. These methods have been successfully applied to solve multi-criteria complex classification problems in many domains, including economical issues. In this paper we discuss features of some supervised classification methods based on decision trees and apply them to the direct marketing campaigns data of a Portuguese banking institution. We discuss and compare the following classification methods: decision trees, bagging, boosting, and random forests. A classification problem in our approach is defined in a scenario where a bank’s clients make decisions about the activation of their deposits. The obtained…
Ensemble methods for ranking data with and without position weights
2020
The main goal of this Thesis is to build suitable Ensemble Methods for ranking data with weights assigned to the items’positions, in the cases of rankings with and without ties. The Thesis begins with the definition of a new rank correlation coefficient, able to take into account the importance of items’position. Inspired by the rank correlation coefficient, τ x , proposed by Emond and Mason (2002) for unweighted rankings and the weighted Kemeny distance proposed by García-Lapresta and Pérez-Román (2010), this work proposes τ x w , a new rank correlation coefficient corresponding to the weighted Kemeny distance. The new coefficient is analized analitically and empirically and represents the main…
Zastosowanie metody TDABC do szacowania kosztów działań informacyjnych pośredników w obrocie nieruchomościami
2016
W niniejszej pracy do szacowania kosztów działań informacyjnych pośredników w obrocie nieruchomościami wykorzystano metodę TDABC. W celu przedstawienia i analizy działań informacyjnych posłużono się algorytmem w postaci schematu blokowego. W algorytmie tym zawarto charakterystykę zmiennych (tzw. nośników działań) oraz opisy działań informacyjnych realizowanych przez pośredników. Poszczególne opisy wzbogacono o zmienne mające bezpośredni wpływ na czas ich realizacji, a także średnie czasy ich wykonania. Czasy realizacji oszacowano na podstawie badań eksperymentalnych i ankietowych. Opracowane ogólne równanie czasowe dla dowolnego przebiegu procesu wynikającego z realizowanych czynności pośre…
Religijna motywacja postu
2016
The research of the religious motivation of fast in the light of the theory and practice, within the framework of three great monotheistic religions, came to the following conclusions: fasting, as a religiously motivated act, expresses its deep conviction about depending on the man and his fate from God; may be motivated by the need to show contrition before God for the committed sins; expresses hu mility in the face of the threatening danger; as a way of preparation, purifiation before major holidays; as one of the elements in commemoration of important events; as the source of peace and balance in the individual and social life; is a tool to help tame the passions; prepares for a new phas…
Performing Sound of the Past: Remix in Electronic Dance Music Culture
2014
The term remix, defined as an activity of taking data from pre-existing materials to combine them into new forms according to personal taste, relates to various elements and areas of contemporary culture. Whichever model used, consideration of the remix depends on recognition of pre-existing cultural codes. Therefore, as a second layer, the remix relies on the authority of the original and it functions at the meta-level. The audience may see a trace of history with the pre-existing object and the meaning creates in the viewer(s), reader(s), listener(s) or, in the contemporary world of DJs and popular electronic dance music culture – in dancer(s). With the aim of specifying modes of creating…
IL RETROFIT ENERGETICO. L'EDILIZIA RESIDENZIALE POST-BELLICA DI PALERMO
2015
Il patrimonio edilizio italiano è composto principalmente da costruzioni realizzate nel secondo dopoguerra, quando la speculazione economica e l'urbanizzazione hanno prodotto edifici con caratteristiche di scarsa qualità architettonica ed energetica. Agire sul rendimento energetico degli edifici esistenti, adattandoli alle caratteristiche richieste dalla normativa, a parità di condizioni di comfort, rappresenta una strategia importante per la riduzione dei consumi energetici e per la tutela dell'ambiente. Attraverso l'applicazione di tecnologie e metodologie innovative e la scelta di investimenti adeguati, il retrofit energetico può rappresentare oggi la principale opportunità di crescita i…
A methodology for the control of the residual lifetimes of carbon fibre reinforced composite pressure vessels
2005
International audience; Pressure vessels must be periodically proof tested. Traditional techniques for metal vessels are inapplicable for composite vessels as the latter do not break by crack propagation so that the reasoning behind the traditional testing procedures is not appropriate. Damage accumulation leading to the degradation of a composite vessel is by fibre failure. Fibres show a wide distribution in strengths and loading a composite inevitably breaks some. The method which has been developed is supported by an analysis of delayed fibre failure due to the relaxation of the resin around fibre breaks. This provokes overloading of intact fibres neighbouring breaks. The time until a cr…
Heart rate and other risk factors in outpatients with stable coronary artery disease in Latvia
2011
Heart rate and other risk factors in outpatients with stable coronary artery disease in Latvia The aim of the study was to characterise coronary artery disease (CAD) outpatients in Latvia by risk factors (RF) including heart rate (HR), physical examination data, clinical data and treatment. Twelve practitioners had each examined and questioned 6 to 12 patients with established CAD (n = 120). The most frequent cardiovascular (CV) RF and co-morbidity were dyslipidemia (94.2%) and hypertension (78.3%), respectively. Prevalence of increased resting HR (≥70 bpm) was 35.9% and 33.6%, when measured by pulse palpation and electrocardiography, respectively. Regarding other RFs, prevalence of treated…
