We propose a novel automata model over the alphabet of rational numbers, which we call register automata over the rationals (RAℚ). It reads a sequence of rational numbers and outputs another rational number. RAℚ is an extension of the well-known register automata (RA) over infinite alphabets, which are finite automata equipped with a finite number of registers/variables for storing values. Like in...
In this paper, we mainly investigate capacity scaling laws of the mobile ad hoc social networks (MAHSNs)where social networking applications are implemented over the underlying mobile ad hoc networks. We model the real-world mobility pattern of mobile social users by introducing a clustered model that defines two levels of mobility, i.e., Strong mobility and weak mobility, according to the impacts...
Gene regulation studies reveal unknown biological functions in disease progression. As more time-course datasets become available, interactions among the regulators and their associated target genes may better describe the evolution of gene regulatory networks. Currently in many research studies, interaction delay is not considered. Such delay is embedded in the network due to the intrinsic temporal...
high-level talent development has become one of the key constraints for China's transition to powerful country. According to China's current development plans and personnel structure, this article made an in-depth analysis of the problems in the developing of high-level talents, introducing the theory of competency model and modern ideas of HRD, Constructing the high-level talents development system...
In order to develop an effective technical methodology for environmental pollution data management and modeling, this paper propose an integrated framework for pollution modeling based on the GIS database. Three layers, including the pollution data management layer, the modeling and analysis layer, and the application layer, construct the complete framework. Design issues of the framework are discussed...
Traffic flow is a fundamental measure in transportation. Accurate traffic flow prediction also is crucial to the development of intelligent transportation systems and advanced traveler information systems. A novel multiscale wavelet support vector regression method (MW-SVR) is proposed for traffic flow prediction. Based on wavelet multi-resolution analysis, a scaling kernel function with multi-resolution...
Geophysical model function (GMF) is the basis and prerequisite for the ocean surface wind vector retrieval with scatterometers. Among many operational models, the Qscat-1 model was specifically developed for SeaWinds scatterometer and is being applied to its operational wind retrieval. This paper is to validate the accuracy of the Qscat-1 model by using some SeaWinds Level 2 data and corresponding...
