The PLuTo scheduling algorithm is a well-known algorithm for automatic scheduling in the polyhedral compilation model. It seeks linearly independent affine partition mappings for each statement of a Static Control Program (SCoP), such that total communication is minimized. In this paper we show that this algorithm can be sensitive to the layout of the global constraint matrix thus resulting to ...

In standard wavelet methods, the empirical wavelet coefficients are thresholded term by term, on the basis of their individual magnitudes. Information on other coefficients has no influence on the treatment of particular coefficients. We propose and investigate a wavelet shrinkage method that incorporates information on neighboring coefficients into the decision making. The coefficients are con...

Project management office (PMO) is a new emerging concept in Iranian construction industry. Executives expect this organizational unit to add value to the business, and meet the demands of stakeholders by performing specialized tasks ranging from providing project management support to portfolio management. In this regard, PMO managers have long faced the question of how to improve the performa...

Fifty years ago, the optimization of thermoelectric devices was analyzed by considering the relation between optimal performances and local entropy production. Entropy is produced by the irreversible processes in thermoelectric devices. If these processes could be eliminated, entropy production would be reduced to zero, and the limiting Carnot efficiency or coefficient of performance would be o...

Multidimensional continuous-time Markov jump processes [Formula: see text] on [Formula: see text] form a usual set-up for modeling [Formula: see text]-like epidemics. However, when facing incomplete epidemic data, inference based on [Formula: see text] is not easy to be achieved. Here, we start building a new framework for the estimation of key parameters of epidemic models based on statistics ...

throughout history dams have been important structures in water storage. to avoid overtopping, damage, and or failure of a dam, adequate spillway is needed to release excess water from upstream floods. researchers found that spillways have to be made nonlinear in order to reach an economic structure with high performance. a piano key weir is one of the best solutions. piano key weirs are the mo...

an integrative approach of data envelopment analysis (dea) and malmquist productivity indicator for performance analysis of projects in subsea r&d; center (srdc) is presented. it is noticeable that, an output based model with constant efficiency was used for data analysis. furthermore, since the dea approach is merely used for homogeneous units, it was assumed that all the projects according to...

Measuring or predicting the distribution of oxygen concentration in waste rock underneath a soil cover is an important aspect of cover performance evaluation. The oxygen decay coefficient is a key parameter in the prediction. In the present study, a method calculating oxygen decay coefficient from oxygen consumption rate is developed. The decrease in oxygen concentration over time measured abov...
