In this study, we explore long short-term memory recurrent neural networks (LSTM-RNNs) for speech enhancement. First, a regression LSTM-RNN approach for a direct mapping from the noisy to clean speech features is presented and verified to be more effective than deep neural network (DNN) based regression techniques in modeling long-term acoustic context. Then, a comprehensive comparison between the...
A novel robot arm called deformable arm for the service robot is presented in this paper. A flexible working space and the ability to deal with multiple tasks are obtained with a single arm by changing the arm shape. However more flexible use brings difficulties in actual use, the arm's parameters will be changed with the different arm structure and cannot be calibrated with conventional methods....
On the purpose to adapt to ever complicated business models, an efficient consistency checking approach is needed for Business Process Model Repository to manage Multi-View models. We present a consistency checking framework to resolve the problems for service-based application. Firstly, based on business model analysis, a Multi-View business meta-model is built to act as a referred framework to find...
The optical tweezers has been found to have many biomedical applications in trapping macromolecules and cells. A recent theoretical study has shown that under appropriate conditions acoustic trapping is also possible [1]. Compared to the optical tweezers, the acoustic tweezers is more useful in light opaque media. In this paper, first we present the range where a particle can be trapped in single...
A three-dimensional (3D) thermo-elastic stress model based on the displacement method was developed to study the thermal stress distribution in the solidified silicon ingot in a directional solidification process. The temperature field was obtained from a 3D global simulation of heat transfer in the furnace. A new coupled model was developed to account for the interaction between the silicon ingot...
Based on the reusability and interoperability of High Level Architecture (HLA), a distributed equipment maintenance support effectiveness evaluation simulation system model is built by combining with the current demands of the equipment maintenance support effectiveness evaluation. A new simulation system framework architecture and hardware architecture are established. At last the simulation system...
Service composition becomes the most interesting challenges in the Web services area. In this paper, the quality of service (QoS)-aware composition of Web services is discussed. In the existing work, heuristic or intelligent optimal algorithms are adopted directly upon the complex process model of a composite service, which means different flow constructs (e.g. sequence, selective, simultaneous, combination,...
