Supply chain management aims at delivering goods in the shortest time at the lowest possible price while ensuring the best possible quality and is now vital to the success of the online retail business. Executing effective warehouse site selection has been one of the key challenges in the development of a successful supply chain system. While some effective strategies for warehouse site selection...
Wireless Sensor Networks are sets of thousands or more of sensor nodes with very small size and limited energy, scattered over particular area to sense a certain physical phenomenon. Energy constraints are the most important challenge for these networks to work efficiently for long time. Most existing clustering algorithms are applied without considering the density of region. In this paper, density-aware...
In this paper, a novel algorithm in the contourlet domain is presented for segmenting lumbar vertebra in CT image. Firstly we apply the contourlet transform to the image, use its multiscale and multidirectional characteristics to get the coefficients that they can effectively capture the contours of an image and depict them sparsely. Secondly, C-Means clustering algorithm is applied to derive the...
LEACH (low-energy adaptive clustering hierarchy) is a well-known self-organizing, adaptive clustering protocol of wireless sensor networks. However it has some shortcomings when it faces such problems as the cluster construction and energy management. In this paper, LEICP (low energy intelligent clustering protocol), an improvement of the LEACH protocol is proposed to overcome the shortcomings of...
