A method was developed to determine the contributions of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) to the nitrification potentials (NPs) of soils taken from forest, pasture, cropped, and fallowed (19 years) lands. Soil slurries were exposed to acetylene to irreversibly inactivate ammonia monooxygenase, and upon the removal of acetylene, the recovery of nitrification p...

Steganography is the art of hiding the existence of data inanother transmission medium to achieve secret communication . Steganography method used in this paper is based on biometrics, ie biometric steganography. And the biometric feature used to implement steganography is skin tone region of images. Here secret data is embedded within skin region of image that will provide an excellent secure ...

Rice crop monitoring is an important activity for crop management. This study aimed to develop a phenology-based classification approach for the assessment of rice cropping systems in Mekong Delta, Vietnam, using Moderate Resolution Imaging Spectroradiometer (MODIS) data. The data were processed from December 2000, to December 2012, using empirical mode decomposition (EMD) in three main steps: ...

-An algorithm for human face recognition, which is based on Overlapped Modular Principal Component Analysis Approach on the Cropped Log-polar images, is presented in this paper. In this technique all the image are divided into sub-images called modules and to avoid loss of features at division lines, overlapped subimages are taken through the division lines. This method is applied on the Croppe...

We proposed a watermarking method using a concatenated code and evaluated the method on the basis of IHC evaluation criteria. The criteria include JPEG compression, clipping, scaling, and rotation as attacks. For the robustness of messages, we introduced concatenated code, since it has a high error corrective ability to decode messages against JPEG compression. When a region is cropped from a s...

Project Goal In the Tonight Show with Jimmy Fallon, Fallon has a sketch segment where he swaps the mouth of him and his guest. However, the methods employed are very simple. They merely crop out a fixed portion of two camera images and swap them. Both he and the guest must keep their mouths centered in this cropped region. This often results in some ridiculous looking faces and mouths improperl...

Segmenting axon and myelin from microscopic images is relevant for studying the peripheral and central nervous system and for validating new MRI techniques that aim at quantifying tissue microstructure. While several software packages have been proposed, their interface is sometimes limited and/or they are designed to work with a specific modality (e.g., scanning electron microscopy (SEM) only)...

two different microhabitats (cropped fields versus established date-palm farms) in two different cities in khuzestan province, southwestern iran, were sampled monthly during 2011-2012 in order to assess the role of anthropic uses of soil on the biodiversity of oribatid mites. a total of 17 species of oribatid mites belonging to 10 families and 15 genera were identified (nine species were collec...
