This paper quantifies the scalability of a document store named MongoDB and an extensible store named HBase for processing simple operations using a social networking benchmark named BG (www.bgbenchmark.org). We report on the vertical and the horizontal scalability of both data stores. We quantify speedup and scaleup characteristics of each data store's Social Action Rating (SoAR). SoAR is the highest...
In practice, multiple types of distortions are associated with an image quality degradation process. The existing machine learning (ML) based image quality assessment (IQA) approaches generally established a unified model for all distortion types, or each model is trained independently for each distortion type by using single-task learning, which lead to the poor generalization ability of the models...
Precision agriculture, a modern agriculture system, is a good solution for the implementation of pollution-free agricultural program. The start point of precision agriculture is the collection of agricultural growth data, but it is not an easy job as the APB (Agricultural Production Base) is always far away from city center and located remotely. As a result, the APB is hard to be covered by network,...
A novel method is presented based on a statistical manifold for text-independent speaker recognition. After feature extraction, speaker recognition becomes a sequence classification problem. By discarding time information, the core task is the comparison of multiple sample sets. Each set is assumed to be governed by a probability density function (PDF). We estimate the PDFs and place the estimated...
The universal template for database application system that code can be automatically generated is designed based on layer interface specifications and abstract factory. In this paper we discuss the template architecture,database information processing, data caching, rights management and other key technologies. Finally, by the application of practical engineering projects, we demonstrate that the...
A virtual experiment system for metal creep performance testing is built by virtual reality modeling language (VRML). The structure, function and design principles of the system are described and its implementation procedure is also discussed. The key development process, including object modeling, 3D scene building, VRML connecting to the real-time database, design of interactive virtual 3D scene...
To achieve the production information management of the coning, drawing and twisting workshops, and promote a good and fast development of the textile enterprise, a multi-agent production monitoring and control system based on C/S mode is developed, through analyzing the actual requirements of the workshops, where the communication of the single-port-multi-protocol and a multi-thread data collection...
The human faces recognition has generated much research interest nowadays. However, human faces are very similar in structure with minor differences from person to person. Furthermore, lighting condition changes, facial expressions, and hairstyle variations further complicate the face recognition task as one of the difficult problems in pattern analysis. This paper proposes a new face recognition...
