We study DAG-depth, a structural depth measure of directed graphs, which naturally extends the treedepth of ordinary graphs. We define a DAG-depth decomposition as a strategy for the cop player in the lift-free version of the cops-and-robber game on directed graphs and prove its correctness. The DAG-depth decomposition is related to DAG-depth in a similar way as an elimination tree is related t...

In this paper, we investigate the performance of several existing structural decomposition methods on fully interlocked Crossword Puzzle Problems (CPPs) and draw directions for future research.

E nergy consumption has increased significantly in Iran during the recent decades. In this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. The input-output tables of Iran for the years 1988 and 2001 have been employed as the database of the model. The innovation of this research allows the researchers to stud...

In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

We examined the relationship between the community structure of wood-decaying fungi, detected by high-throughput sequencing, and the decomposition rate using 13 years of data from a forest dynamics plot. For molecular analysis and wood density measurements, drill dust samples were collected from logs and stumps of Fagus and Quercus in the plot. Regression using a negative exponential model betw...

A method for expressive melody synthesis is presented seeking to capture the structural and prosodic (stress, direction, and grouping) elements of musical interpretation. The interpretation of melody is represented through a hierarchical structural decomposition and a note-level prosodic annotation. An audio performance of the melody is constructed using the time-evolving frequency and intensit...

∗ Corresponding author ABSTRACT This study presents a systematic decomposition process to carry out assembly synthesis as a tool during the conceptual design phase of a product. Two configurations obtained by structural topology optimization are decomposed automatically into assemblies consisting of multiple members with simpler geometries. The optimal decomposition can be posed as a graph part...

In order to identify main drivers behind changes in electricity and fuel consumptions in the industrial sector in Jordan; a Laspeyers decomposition technique was used to identify the factors affecting this demand during 1998-2005 years Changes have been disaggregated into production, structural, and efficiency effects. Results of the decomposition analysis prove that rapid increases in industri...
