Fully CMOS compatible Silicon-nanowire (SiNW) Gate-All-Around (GAA) n- and p-MOS transistors are fabricated with nanowire channel in different crystal orientations and characterized at various temperatures down to 5K. SiNW width is controlled in 1 nm steps and varied from 3 to 6 nm. Devices show high drive current (2.4 mA/μm for n-FET, 1.3 mA/μm for p-FET), excellent gate control, and reduced sensitivity to temperature. Strong evidences of carrier confinement are noticed in term of Id-V8 oscillations and shift in threshold voltage with SiNW diameter. Orientation impact has been investigated as well.

Continual CMOS scaling requires the implementation of high-K gate dielectrics with metal gate to alleviate the rapid gate tunneling current increase associated with aggressive EOT scaling. The use of poly-Si gate electrodes on high-K has brought on serious additional problems, including high gate leakage, unable to scale down EOT, Fermi level pinning of the effective gate work function, channel mobility and reliability degradations. These issues are significant to the point where it seems quite likely that both high-K dielectric and metal gate electrodes will be introduced into manufacturing at the same time. The purpose of this paper is to review some of the integration challenges that high-K/metal gate stack technology is facing. This includes thermal stability of high-K against crystallization, phase separation, and interfacial reaction with underlying Si, charges/traps in high-K as well as at interfaces, channel carrier mobility degradation, EOT control and scaling, work function control for dual-gate CMOS integration, and gate stack reliability. The engineering of the high-K/Si as well as metal/high-K interfaces is identified as the most important factor for achieving EOT 1 nm with good performance and reliability. copyright The Electrochemical Society.

Measuring the similarity between 3D models is a fundamental task in 3D models retrieval. In this paper, we propose a new method based on global geometric feature map (GGFM) to represent arbitrary polygonal 3D models. Since 3D polygonal model can be expressed as a set of facets, the GGFM can fast constitute a spherical histogram about the normal orientation and area and position of every facet on the surface of the model. By computing the spherical correlation between the GGFMs of the matched models, similarity of two models can be obtained. Experimental results show that the proposed method performs well in 3D model similarity matching and is invariant to the translation and rotation and scaling of 3D model. Comparing to the existing methods, this method is fast and needs low computation and storage cost since each facet of the model needs to be computed only once in GGFM

The Time-Domain Finite Element Method is used extensively in areas of microwave engineering. However, TD-FEM runs too slow for some simulations to be practical, especially when run on standard personal computers. The propriety of hardware for the acceleration of TD-FEM computations has been investigated. It is well known that the key of TD-FEM is matrix operation. There always be an obstacle that the speedup of dense matrices operations in graphics Processor Units fields. This situation will be improved in next generation. Even though the presence of the obstacle, the standard consumer graphics Processor Units (GPUs) can be used to accelerate TD-FEM simulations by a factor of close to two yet, relative to an Intel CPU of similar technology generation. With OpenGL as the Application Programming Interface (API), a standard commercial graphics card has been programmed to solve a 2-D electromagnetic radiation problem.
We present a new generic problem solving approach for over-constrained problems based on Max-SAT. We first define a Boolean clausal form formalism, called soft CNF formulas, that deals with blocks of clauses instead o...

One research direction to make computers become more active machines is to use audio input with far-field omni-directional microphones, these being required to face the acoustics problem of the meeting scenario. This topic is not only interesting from an artificial listener point-of-view, but also as one of the hottest topics in searchable media. In this paper two noise suppression methods for real meeting audio are evaluated. Because of the usage of hands-free microphones in a meeting environment, the reverberation of meeting rooms and background noise sources such as projector, computer fan have huge impact on speech quality. Two denoising methods, based on statistical Wavelet filtration and short-time Fourier transform are discussed and evaluated. Whilst the quantile technique is suitable for estimating stationary noise (beamer, computer fan), non-stationary sources (closing door, chair movement) can be handled by recursive structure and adaptive temporal gain of the statistical filtration method. Besides, frequency non-linear gain can remove colored noise effectively. The proposed noise reduction methods are evaluated with speaker localizing application applied on the meeting database of the Mistral project. The results show the pros and cons of each method applied on the meeting database.

SVG (scalable vector graphic) is used to describing 2D graphics in XML, which is a text file in fact. SVG has many advantages facing to Web application, such as dynamically showing data and interactivity. As increasing usage of SVG graphics in commercial Web applications for exchanging or publishing data, unauthorized duplication and distribution of SVG data become a mandatory concern for many Web applications. Then how to fulfil copyright protection must be deal with carefully. In this paper, we propose a scheme to protect the copyright of the SVG data based on digital watermark
