Numerical Study on Temporal Domain Discretizing for Hydrogeological Modeling Practices

Abstract

One of the key operations in the construction of hydrogeological models is the transformation of continuous physical systems into discrete models while conserving the aimed model performance level and optimizing the available resources. Such operation is called discretization, and it has to be applied to both spatial and temporal domains in hydrogeology. The present paper deals with the temporal domain discretization. A literature review is given first, and then a parametric study (using 1D flow modeling) is conducted to assess the effects induced by boundary conditions (specified head or specified recharge rate), data temporal resolution and model simulation time step on hydrogeological flow model performances. It was found that the effect induced by the dynamic comportment of a recharge rate boundary condition type is more important than that due to a specified head. For the recharge rate, the time step must be smaller or equal to the data resolution when using Modflow. As for a specified head boundary condition type, it was recommended to take a time step satisfying Δt∞1/(K × Δh).

Spatio-Temporal Analysis of Unemployment Rate in Poland

Abstract

The aim of this paper is to present results of spatio-temporal analysis of unemployment rate in Poland, with the usage of advanced spatial econometric methods. The analysis was done on data collected for ‘powiat’ level between 2006 and 2010. GlS and ESDA tools were applied for visualization of the spatiotemporal data and identification of spatial interactions between polish counties on labor market. Multi-equation spatial econometric models were used to describe unemployment rate in relation to selected social-economic variables.

Collinear Suppression in Texture Segmentation for Temporally Modulated Stimuli

Collinear Suppression in Texture Segmentation for Temporally Modulated Stimuli

Collinear stimuli facilitate the neural signal in the case of Gabor's stimuli when a low-contrast stimulus inside the receptive field is flanked by higher contrast collinear elements located in surrounding regions of the visual space. Our previous studies pointed to the contextual modulation in the case of the textured stimuli. Collinear suppression was observed in 63% of the responses. In the current research we used Gabor's primitives for building the circular texture objects of vertical and diagonal orientation to be recognized on the horizontally-oriented background in the presence of collinear and orthogonal peripheral stimuli. The two-alternative forced choice (2AFC) psychophysical method with constant stimuli was used to gather the responses of the subjects which choose between left or right position of diagonally-oriented stimuli. The experimental stimuli consisted of two circularly shaped objects presented in visual angle of 2.76 degrees. The expositions of the stimuli varied from 13.3 to 93.3 ms arbitrarily. Visual stimuli were presented with a CRS Visage stimulus generator and shown on a CRT monitor of 75 Hz refresh rate. Our new findings support the concept of suppressing the target stimuli of the same orientation in the presence of a peripheral collinear stimulation.

Film and Media as a Site for Memory in Contemporary Art

Abstract

This article explores the relationship between film, contemporary art and cultural memory. It aims to set out an overview of the use of film and media in artworks dealing with memory, history and the past. In recent decades, film and media projections have become some of the most common mediums employed in art installations, multi-screen artworks, sculptures, multi-media art, as well as many other forms of contemporary art. In order to examine the links between film, contemporary art and memory, I will firstly take a brief look at cultural memory and, secondly, I will set out an overview of some pieces of art that utilize film and video to elucidate historical and mnemonic accounts. Thirdly, I will consider the specific features and challenges of film and media that make them an effective repository in art to represent memory. I will consider the work of artists like Tacita Dean, Krzysztof Wodiczko and Jane and Louise Wilson, whose art is heavily influenced and inspired by concepts of memory, history, nostalgia and melancholy. These artists provide examples of the use of film in art, and they have established contemporary art as a site for memory.

On Temporal Behaviour of Solutions in Thermoelasticity of Porous Micropolar Bodies

Abstract

We consider a porous thermoelastic body, including voidage time derivative among the independent constitutive variables. For the initial boundary value problem of such materials, we analyze the temporal behaviour of the solutions. To this aim we use the Cesaro means for the components of energy and prove the asymptotic equipartition in mean of the kinetic and strain energies.

The Impossibility of Temporal Relations Between Non-Identical Times: New Arguments for Presentism

Abstract

I argue that relations between non-identical times, such as the relations, earlier than, later than, or 10 seconds apart, involve contradiction, and only co-temporal relations are non-contradictory, which would leave presentism the only non-contradictory theory of time. The arguments I present are arguments that I have not seen in the literature.

Temporal And Generational Impact On Identity, Home(Land) And Politics Of Belonging Among The Kurdish Diaspora

Abstract

The purpose of this article is to examine the experiences of two generations among the Kurdish diaspora in Sweden: those who migrated as adults and those who were born and/or raised in Sweden. The focus will be on issues of identity, home(land) and politics of belonging with regard to generational and temporal aspects. We will argue that there are significant differences among the older and younger generations with regard to their experiences that demand different theoretical and analytical conceptualisations
