Recently many statistical learning techniques are successfully developed and used in several areas. However, these algorithms sometimes are not robust and does not show good performances. The ensemble method can solve these problems. It is known that the ensemble learning sometimes improves the generalized performance of machine learning tasks as well as makes it robust. However, the combining ...

be used in most geographical locations of interest. In mountainous regions with very long echo delays, some gain would still be achieved by setting z to T/2 without significantly degrading the receiver equalisation capability. The technique has also been validated through testing with more complex Rayleigh fading channel models specified by GSM’ which are typical of particular geographical loca...

in this paper we introduce a new scheme of censoring and study it under the weibull distribution. this scheme is a mixture of progressive type ii censoring and self relocating design which was first introduced by srivastava [8]. we show the superiority of this censoring scheme (psrd) relative to the classical schemes with respect to “asymptotic variance”. comparisons are also made with respect ...

This study assessed land cover (LC) changes in Kahramanmaraş (K.Maraş) and its environs by using multitemporal Landsat and ASTER imagery, respectively belong to 1989, 2000 and 2004. A priori defined nine land cover classes in the classification scheme were urban and built-up, forest, sparsely vegetated areas, grassland, vegetated stream beds, unvegetated stream beds, bare areas, crop fields, an...

The influence of the position of the heart on the form of the electrocardiogram has been known for close on halfa century. It was discussed by Waller (1913 and 1914) and more fully by Einthoven et al. (1913), but the bearing of this fact on the diagnosis of heart disease has not received much attention. The effects of deep inbreathing on the tracing are found to be common, especially in lead II...

Smart agriculture which integrates the with Internet of Things (IoT) has attracted attention since it contributes to increase productivity and quality crops, reduce energy consumption facilitate farmers. Wireless sensor networks (WSNs) unmanned aerial vehicles (UAVs) are two most commonly deployed devices that used for enabling smart agriculture. In this paper, we design a collaborative WSN-UAV...

Agriculture has multiple functions to fulfill for the development of the Sub-Saharan Africa countries: a source of growth, an instrument for poverty reduction, and a contribution to the provision of environmental services. Yet, it is still used far below potential, with gains in land and labor productivity lagging below those of other regions. Successful use of agriculture for development will ...

identifying role of extension system in adoption of new technologies have important role to developing favorable extension systems. for supporting sustainable agriculture in iran needs extension systems to be carefully thought and accurately implemented. the purpose of this is analyzing role of extension activities in adoption of sustainable agriculture. based on the results the attending agric...

the present study introduces a new technique of homotopy perturbation method for the solution of systems of fractional partial differential equations. the proposed scheme is based on laplace transform and new homotopy perturbation methods. the fractional derivatives are considered in caputo sense. to illustrate the ability and reliability of the method some examples are provided. the results ob...
