Abstaining from voting is widespread in a voting process. Those candidates not be approved of are generally presumed to be disapproved in approval voting with abstention votes, which may ignore some genuine and meaningful information hidden in abstention votes. This paper constructs an analyzing model for abstention votes based on incomplete information system (IIS) and vague sets, and gives a new...
With the emergence of machine-to-machine (M2M) communications, trillions of devices will soon be interconnected to support new applications and services. The success of M2M communication relies on the scalability of underlying network architectures and protocols. In this paper, an adaptive multi-channel medium access control (MAC) protocol is proposed to address the scalability issue in M2M communications...
The Internet of Things presents the user with a novel means of communicating with the Web world through ubiquitous object-enabled networks. Cloud Computing enables a convenient, on demand and scalable network access to a shared pool of configurable computing resources. This paper mainly focuses on a common approach to integrate the Internet of Things (IoT) and Cloud Computing under the name of CloudThings...
This paper proposes a stabilized algorithm to design a high performance locking-free lowest order quadrilateral finite element for Reissner-Mindlin plates. It is based on the Hellinger-Reissner variational principle, which includes variables of displacements, shear stresses and bending moments. By adding a stabilization term of least-squares to the original hybrid scheme, and allowing independent...
Architecture of push-enabled AMI reference model is proposed in this article. In the model, all actors in the Smart Grid can be treated as object things. When the push-based managerial operations with form of query initiated from head-ends, a Resource Discovery System can analyze the intension of the query and recommend the list of object things meet the criteria. The managerial operation can therefore...
In this paper, a new speaking rate-controlled Mandarin TTS system based on a speaking rate-dependent hierarchical prosodic model (SR-HPM) [6] is proposed. In the training phase, a data-driven approach is employed to automatically build the SR-HPM directly from a large prosody-unlabeled speech database containing utterances of various speaking rates. The SR-HPM comprises 15 sub-models designed to describe...
In this paper, an automatic and unsupervised method based on context-dependent hidden Markov model (CD-HMM) is proposed for labeling the phrase boundary positions of a Mandarin speech synthesis database. The initial phrase boundary labels are predicted by clustering the durations of the pauses between every two prosodic words in an unsupervised way. Then, the CD-HMMs for the spectrum, F0 and phone...
An inductor switching DC/DC boost regulator with adaptive off/on time (AOOT) control is proposed in this paper. This system works with adaptive-off-time control in CCM while adaptive-on-time control in DCM. The burden caused by the switching frequency variation is reduced due to the quasi-fixed frequency switching by adaptive-off-time modulation under heavy-load condition. In DCM, adaptive-on-time...
In this paper, the research advances in printed microwave and millimeter wave antennas in the State Key Laboratory of Millimeter Waves (SKLMMW) are reviewed, including printed omnidirectional antennas, dual-band antennas, ultra-wideband antennas with or without frequency notches, multi-beam antennas, low sidelobe antennas, filtennas, frequency scanning antennas, reflectarray, and lens etc.
In this study, the characteristics of non-polar double heterojunction GaN/ InxGa1−xN solar cells with various indium contents are numerically investigated under AM 1.5 global spectrum using finite element analysis. By smoothing the interface band edge offset with graded junction, we see the enhancement on short circuit current and power conversion efficiency. The maximum efficiency of the simulation...
Much effort has been put into developing multi-channel retinal prosthetic devices. Currently, even the most advanced prostheses do not have enough channels to provide vision to a desirable level. In this paper, we present a system design and a packaging scheme for a 512-channel intraocular epiretinal implant. Both a wireless power coil (with high transfer efficiency) and a data coil are included for...
Geophysical inversion algorithms often introduce artifacts near sharp intensity transitions and image boundary. We presented a iterative restoration algorithms to restore the true inversion image and remove the artifacts. We also presented a ringing metric to evaluate the quality of images restored based on the human visual system. According to types of ringing artifacts, two ringing metrics is used...
We demonstrated a two-section 1.55μm laser with an air gap in the middle section. When two DFB lasers are powered together, an optical heterodying operation can produce microwave signals up to 44 GHz.
To provide QoS support in HF networks, this paper analyzes the traffic models in HF network, combined with the characteristics of HF network. According to these traits, the requirements that need to be considered in queue scheduling algorithm of HF gateway is given. JoBS algorithm, which may satisfy the requirements, is suggested to be used in HF gateways. Through simulation in NS2, JoBS is proven...
This paper presents an improved unit selection and waveform concatenation speech synthesis method by gathering and utilizing human feedbacks on synthetic speech. Firstly, a set of texts are synthesized by the baseline unit selection synthesis system. Each prosodic word within the synthetic speech is then evaluated as a natural one or an unnatural one by listeners. In our proposed method, these natural...
In this paper, we introduce a newly-created corpus of whispered speech simultaneously recorded via a close-talking microphone and a non-audible murmur (NAM) microphone in both clean and noisy conditions. To benchmark the corpus, which has been freely released recently, experiments on automatic recognition of continuous whispered speech were conducted. When training and test conditions are matched,...
Characterizing aggregated GPRS traffic and user traffic is important for performance evaluation and optimization of the networks. In this paper, we investigated these characteristics and their relationship. Our analysis are based upon user-level flow traces from passive monitoring of more than 1000 GPRS/EGPRS cell sites connected to the same SGSN at Gb interface. The traffic traces are from a major...
We present a cross-language knowledge integration framework to improve the performance in large vocabulary continuous speech recognition. Two types of knowledge sources, manner attribute and prosodic structure, are incorporated. For manner of articulation, cross-lingual attribute detectors trained with an American English corpus (WSJ0) are utilized to verify and rescore hypothesized Mandarin syllables...
In this paper, we focus on recovering a 3-D depth map from a single image via ground-vertical boundary analysis. First, we generate a ground map from the input image based on the spectral matting method, followed by a spatial geometric inference. After that, we derive the depth information for the ground-vertical boundaries. Unlike conventional approaches which generally use plane models to reconstruct...
Research has shown that people can learn many nouns (i.e., word-referent mappings) from a short series of ambiguous situations containing multiple word-referent pairs. Associative models assume that people accomplish such cross-situational learning by approximately tracking which words and referents co-occur. However, some researchers posit that learners hypothesize only a single referent for each...
