differential scanning calorimetry (dsc), temperature programmed desorption mass spectrometry (tpd-ms) and small angle neutron scattering (sans) were used to investigate co2 uptake by the wyodak coal. adsorption of carbon dioxide on wyodak coal was studied by dsc. the exotherms evident at low temperatures are associated with the uptake of co2 suggesting that carbon dioxide interacts strongly wit...

Structural change plays an important role in developing any economy, so understanding it is critical to make policies that increase total factor productivity. The structural change that leads to an efficient resource allocation after trade reforms is desirable; the key factor that can affect the relation of "structural change and trade liberalization" with productivity is the quality of institu...

The aim of this study is decomposition of the changes in energy consumption with emphasizing the structural changes in Iran during 2001-2011 using Input- Output Structural Decomposition Analysis (I_O SDA). Structural changes in this study represent the changes in structure of intermediate input in sectors and also changes in structure of final demand categories. Structural changes in intermedia...

Forecasting strategies that are robust to structural breaks have earned renewed attention in the literature. They are built on weighted averages downweighting past information and include forecasting with rolling window, exponential smoothing or exponentially weighted moving average and forecast pooling. These simple strategies are particularly attractive because they are easy to implement, pos...

Many studies analyzed in depth how aging affects aggregate economic performance. But analyses of these effects on the employment structure are scarce and they do not consider that consumption patterns, the supply of goods and services, and also sectoral labor productivity are all likely to adjust to aging and will change. Hence, regression analysis of sectoral employment shares is proposed that...

We document for a broad panel of advanced economies that increases in GDP per capita are associated with a shift in the composition of value added to sectors that are intensive in high-skill labor. It follows that further development in these economies leads to an increase in the relative demand for skilled labor. We develop a two-sector model of this process and use it to assess the contributi...

This paper studies the spatial implications of structural change. The secular decline in spending on agricultural goods hurts workers in rural locations and increases the return to moving towards nonagricultural labor markets. We combine detailed spatial data for the U.S. between 1880 and 2000 with a novel quantitative theory to understand this process and to quantify its macroeconomic implicat...

This study suggests and tests a model for the systematic evaluation of management activities in company-wide standard software implementations using the example of a business intelligence (BI) software package. The proposed model builds on an extended technology acceptance model (TAM), previous research on IT implementation success factors and reviews of relevant change management variables. Us...

Most websites undergo a redesign from time to time. Along with the change of the appearance of the site comes a different document structure. Hence, redesigns can be detected by observing changes in the structural similarity of monitored HTML documents. Assuming further to monitor not a fixed document set but a series of the newest documents (e.g. provided by an RSS feed) transforms the task of...

By continuing to use fossil fuels we are bound to pollute the atmosphere, and consequently, unwanted greenhouse and climate change effects will come to dominate every part of the earth. Wind power energy represents an interesting alternative to traditional forms of obtaining energy. However, the efficiency of wind power strongly depends on the control methods that play a significant role in eli...
