In this paper, interference-aware precoding schemes for multicell MIMO/TDD systems are discussed. By exploiting channel reciprocity in TDD systems, we propose decentralized linear precoding schemes without feedback. We first define a new metric called signal to generating interference plus noise ratio (SGINR). Based on SGINR, we propose a single stream scheme that balances between maximizing th...

abstract spatial prediction of soil organic carbon is a crucial proxy to manage and conserve natural resources, monitoring co2 and preventing soil erosion strategies within the landscape, regional, and global scale. the objectives of this study was to evaluate capability of artificial neural network and multivariate linear regression models in order to predict soil organic carbon using terrain ...

This paper proposes an index for nodal market power detection in power market under locational marginal pricing (LMP). This index is an ex-ante technique to detect the market power. More precisely, this criterion detects the potential of exercising market power regardless of detecting the actual market power. Also it is obvious that pricing and market clearing method affect the potential of exe...

At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. This paper presents the first method in computer graphics that combines uplift and hydraulic erosion to generate visually plausible terrains. Given a user-painted uplift map, we generate a stream graph over the enti...

There is much current interest in supporting continuous queries on data streams using generalizations of database query languages, such as SQL. The research challenges faced by this approach include (i) overcoming the expressive power limitations of database languages on data stream applications, and (ii) providing query processing and optimization techniques for the data stream execution envir...

Rill erosion frequently occurs in Mediterranean cultivated landscapes due to high rainfall intensities, low soil organic matter concentrations and low vegetation coverage. Among other rill erosion mitigation practices, farmers have historically built ditch networks to intercept runoff upstream of cultivated plots. However, the construction and maintenance of these ditches generate indirect cost...

In this paper, a mathematical model for symmetrical multi-layer sheet rolling, in which the layers are unbounded before rolling, by using the upper bound method and stream function theorem is proposed. Using this model, we can investigate the plastic deformation behavior of sheets at the roll gap during rolling. Effect of various rolling conditions such as initial and final thickness and flow s...

Several studies have indicated a key role for dorsal stream processing in lexical decoding. To examine this relationship further, performance on orthographic and phonological reading tests was compared with both steady-state visual evoked potentials and a putative behavioral measure of dorsal stream processing, coherent motion detection. Frequency analysis of the visual evoked potential data sh...

This paper proposes a method to improve landscape-pollution interaction regression models through the inclusion of a variable that describes the spatial distribution of a land type with respect to the pattern of runoff within a drainage catchment. The proposed index is used as an independent variable to enhance the strength, as quantified by R2 values, of regression relationships between empiri...
