A structure-activity relationships based on an original molecular descriptors family method has been developed and applied on a sample of substituted 1,3,4thiadiazoleand 1,3,4-thiadiazoline-disulfonamides. Forty compounds were studied for their inhibition activity on carbonic anhydrase I. The molecular descriptors family was generated based on complex information obtained from compounds structu...

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...

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 ...

The strategies to perform the transportation of agricultural commodities by truck in Brazil are a challenge to decision making. This paper brings together widely held theories that are vertical coordination and decision analysis, to present a discussion of decision making in organizations. From a model capable to process main objectives, multiple criteria and variables found in transport vertic...

This paper presents a comparison between two approaches to sensor dibration. A c c o r d i to one approach, cnlled explicit, an estimator compares the sensor readiags to reference rendings, auad uses the difference between the two to estimate the calibration parameters. Accordii to the other approach, called implicit, the sensor error is integrated to form a different entity, which is then comp...

performance of chamomile (matricaria chamomilla l.) was evaluated on twelve transplanting dates that were arranged at 30 days interval; during 2013-2014 on experimental field of wondo genet agricultural research center; using rcbd design with three replications. transplanting time exerted a very highly significant (p<0.0001) influence on plant height, flower yield and essential oil yield; essen...

This paper focuses on robust performance analysis of a closed loop fractional order system through a sensitivity approach. The characteristic ratio assignment method is selected to attain a desired closed loop transient response. Then, we compute the sensitivity of such a desired transfer function with respect to its characteristic ratio and we explore its specifications. The relation between t...
