This study assesses the contribution of LIDAR altimetry, multi-return and intensity information, and aerial photos to coastal wetland investigation. Aerial photos in this area work as reference data to assess the accuracy of the experiment. The performance of Lidar data resources was tested alone with the adaptive TIN algorithms to separate ground points. Multi-return information was employed t...

Article history: Received 6 August 2012 Received in revised form 31 January 2013 Accepted 6 February 2013 We report preliminary results of a new observational study of microwave-frequency electromagnetic radiation that is emitted by lightning discharge processes. Radiation was observed with a ceramic patch antenna and a digital radio receiver tuned to a center frequency of 1.63 GHz and a bandwi...

this paper considers the multi-depot vehicle routing problem with time window in which each vehicle starts from a depot and there is no need to return to its primary depot after serving customers. the mathematical model which is developed by new approach aims to minimizing the transportation cost including the travelled distance, the latest and the earliest arrival time penalties. furthermore, ...

This paper presents a generic technique for mapping parallel algorithms onto parallel architectures. The proposed technique is a fast recursive mapping algorithmwhich is a component of the Cluster-M programming tool. The other components of Cluster-M are the Speciication module and the Representation module. In the Speciication module, for a given task speciied by a high-level machine-independe...

To address the security risk caused by fixed offset mapping and limited recoverability of random used in image watermarking, a self-embedding fragile watermarking algorithm based on deneighbourhood are proposed. First, is divided into several 2 × blocks, authentication watermark recovery generated average value blocks. Then, denighbourhood implemented as, for each block, its block randomly sele...
