Pervasive smartphones that embed a variety of sensors enable us to sense and learn about the physical environment around us, even the society we live in. However, the sheer volume of data collected through participatory sensing can deeply hamper the performance of various applications (e.g., data processing time and transmitting cost). In this paper, we proposed a method to reduce the volume of sensor...
Popular real-time public events often cause upsurge of traffic in Twitter while the event is taking place. These posts range from real-time update of the event's occurrences highlights of important moments thus far, personal comments and so on. A large user group has evolved who seeks these live updates to get a brief summary of the important moments of the event so far. However, major social search...
The pipeline transportation of waxy crude oil is a problem both at home and abroad. In this paper, a novel nanohybrid pour-point depressant (PPD) was used to decrease the pour point and viscosity of waxy crude oil. The pour point and apparent viscosity of waxy crude oil was decreased significantly upon addition of the nanohybrid PPD, and the long-term stability of the nanohybrid PPD was superior to...
A novel approach to image inpainting is introduced in this paper. The novelty lies in the combination of the MRF inpainting technique and a multiscale information fusion mechanism. This combination uses both local information via the MRF technique and global information via the multi-scale mechanism to improve the image inpainting quality. The proposed algorithm consists of three steps. In the first...
The paper discussed how improve the detection probability of small targets in the complicated background of low signal noise ratio, algorithm of an improved image enhancement and digital filtering are presented for improve image quality, and improve signal to noise ratio, that is achieve the suppressing background noise and enhance the purpose of small targets. For requirements of real-time infrared...
A novel approach to image inpainting is introduced in this paper. The novelty lies in the combination of pixel-diffusing technique and a user interaction mechanism. This combination takes both local geometrical information via the pixel-diffusing technique and global structure information via the user interaction to improve the image inpainting quality. The user interaction mechanism manually specifies...
AdaBoost algorithm is an effective license plate detection method in the field of license plate recognition technology. A through analysis of three boosting algorithms (namely Discrete, Real and Gentle AdaBoost) is presented for license plate detection, including the algorithm details and experiment comparisons. The experimental results show the Gentle AdaBoost algorithm obtains an overall better...
A texture-based Bayesian document segmentation method is investigated in this paper. This Bayesian method is used to fuse texture likelihood and prior contextual knowledge to achieve document segmentation. The texture likelihood is based on a complex wavelet domain hidden Markov tree (HMT) model and the prior contextual is based on a hybrid tree model. A redundant wavelet domain Gaussian mixture model...
Cholera is a severe diarrheal disease that may spread rapidly. Vaccination is considered a valid measure against it. We developed a new vaccine candidate, IEM109, against Vibrio cholerae. To generate this candidate, a chromosomal fragment containing the TLC element, attB of the CTXΦ integration site, and RTX cluster responsible for the cytotoxic activity for mammalian cells was deleted through homologous...
The cholera toxin (CT) genes ctxAB are carried on a lysogenic phage of Vibrio cholerae, CTXΦ, which can transfer ctxAB between toxigenic and nontoxigenic strains of bacteria. This transfer may pose a problem when live oral cholera vaccine is given to people in epidemic areas, because the toxin genes can be reacquired by the vaccine strains. To address this problem, we have constructed a live vaccine...
