Minimum theorems for displacement and plastic strain rate histories in structural elastoplasticity
1975
The finite element method approach is used to obtain formulations of analysis problems relative to elastic-plastic structures when subjected to prescribed programmes of loads, and under the restrictive hypotheses:a) the yielding surfaces are piecewise linearized, andb) the plastic flow-laws are supposed to be of holonomic type within a single “finite” time interval. For mulations are given as linear complementarity problems and quadratic programming problems: one pair of formulations in terms of velocity and plastic multiplier rate histories, and another pair in terms of plastic multiplier rate histories only. The solutions are shown to be characterized by two minimum principles for displac…
Ekonomiczne efekty programu "Rodzina 500 +" w świetle badań budżetów gospodarstw domowych w Polsce
2019
W artykule przedstawiono wyniki badań wpływu programu "Rodzina 500+" na poziom życia gospodarstw domowych w Polsce. W tym celu przeprowadzono analizę porównawczą relacji między samooceną poziomu zaspokajania podstawowych grup potrzeb a dochodami, wydatkami konsumpcyjnymi i wybranymi charakterystykami gospodarstw domowych klasyfikowanych według kryterium typu biologicznego. Porównywano sytuację gospodarstw domowych w roku 2015 i 2017, czyli w roku bezpośrednio poprzedzającym wprowadzenie programu świadczeń wychowawczych i roku, w którym świadczenie to wypłacane było już przez pełne 12 miesięcy. Analiza wykazała, że istniała silna zależność oceny własnej sytuacji ekonomicznej gospodarstw zaró…
Virtual Reality and Psychopathology
2009
Progress in the development of Virtual Reality (VR) is faster than has been forecast, which makes deep reflection on its potential uses and abuses absolutely necessary. The current article focuses on the analysis of some of the applications and implications of VR on psychopathology. It is obvious that they could be many, but we are only focusing on: (a) VR as a model to answer some central questions that traditionally have intrigued psychopathologists; and (b) VR and possible psychopathological experiences. We believe that VR has the potential of becoming a tool that will allow psychopathology to challenge and modify theoretical positions already established, and to pose new ones. This new …
Hierarchical Evolutionary Algorithms and Noise Compensation via Adaptation
2007
Hierarchical Evolutionary Algorithms (HEAs) are Nested Algorithms composed by two or more Evolutionary Algorithms having the same fitness but different populations. More specifically, the fitness of a Higher Level Evolutionary Algorithm (HLEA) is the optimal fitness value returned by a Lower Level Evolutionary Algorithm (LLEA). Due to their algorithmic formulation, the HEAs can be efficiently implemented in Min-Max problems. In this chapter the application of the HEAs is shown for two different Min-Max problems in the field of Structural Optimization. These two problems are the optimal design of an electrical grounding grid and an elastic structure. Since the fitness of a HLEA is given by a…
The Role of Translation and EU-Texts in the English BA Programme : Exploring Hungarian College Graduates' Work Experiences and Views
2015
Despite recent convincing arguments emphasizing the benefits of using translation in foreign language learning and teaching, there is little empirical research focusing on existing educational practices. This study aims to fill this gap by investigating the case of an English bachelor’s programme at a Hungarian college, which has integrated translation and specialised EU-texts into the curriculum in a systematic way in an attempt to stay abreast of the current global social transformations and address local needs. The participants of the survey were graduates of the English BA programme who have completed the optional EU specialisation module. The research aimed to find out about graduates’…
Prediction of BOD5 content of the inflow to the treatment plant using different methods of black box - the case study
2020
The publication presents the possibility of modeling in a 1 d advance of the content of organic compounds in the influent wastewater to the treatment plant, where the content of these compounds is determined by both the biochemical and chemical oxygen demand. To predict the quality of the wastewater at the inflow a set of indicators where used to make measurements on a daily basis. In order to develop statistical models 3 methods where used, namely: multivariate adaptive regression splines (MARS), boosted trees (BT), and genetic programming (GP). The carried-out calculations showed that, to calculate the BOD5 there can only be used models developed on the basis of the value of daily wastewa…
Monitoring Bunker Cave (NW Germany): A prerequisite to interpret geochemical proxy data of speleothems from this site
2011
Summary Monitoring cave environments is important to understand processes in karst systems. If stalagmites from a specific cave are used as archives of past climate variability, a quantitative understanding of the soil–karst–speleothem system is crucial. The monitoring program performed in Bunker Cave (NW Germany), which includes monthly collection of climatological data as well as air and water samples from the cave and the overlying soil since 2006, is a prerequisite for the interpretation of speleothem data from the cave in terms of climate variability. The results show that Bunker Cave is a homogeneously ventilated cave with rather low pCO2 values of 580–1200 ppmv, which lacks strong se…
Estimación mediante programación genética de los patrones del suelo humectantes para el riego por goteo
2012
Drip irrigation is considered as one of the most efficient irrigation systems. Knowledge of the soil wetted perimeter arising from infiltration of water from drippers is important in the design and management of efficient irrigation systems. To this aim, numerical models can represent a powerful tool to analyze the evolution of the wetting pattern during irrigation, in order to explore drip irrigation management strategies, to set up the duration of irrigation, and finally to optimize water use efficiency. This paper examines the potential of genetic programming (GP) in simulating wetting patterns of drip irrigation. First by considering 12 different soil textures of USDA–SCS soil texture t…

Internetbankas administrēšanas moduļa izstrādāšana
2016
Internetbankas administrēšanas modulis (turpmāk – IB Admin) ir neatņemama daļa no pašreizējas internetbankas sistēmas un tiek izmantota katru dienu. Tas darbojas 24 x 7 režīmā un, kā internetbankas daļa, tas ir biznesa kritiska sistēma. Veco internetbankas administrēšanas sistēmu izstrādāja, apmēram, pirms 15 gadiem un nekad nebija būtiski uzlabota. Administrēšanas sistēma izmantoja novecojušas tehnoloģijas, un ir vecmodīga un nav ērti izmantojama no lietotāja perspektīvas. Gadījumā liela pieprasījuma skaita tika novērotas veiktspējas problēmas – darbojas ļoti lēni vai vispār uzkaras. Izmantojot vecas tehnoloģijas un sistēmas arhitektūru, ļoti apgrūtina un palēnina darba procesu, piemēram, …
