Mechanisms with springs were used for variety of purposes from the 2nd century BC in ancient China. Barbed-springs locks and original crossbows are representative types that belong to reconfigurable mechanisms. Several available books with mechanical illustrations introduce the structures and functions of mechanisms with springs in ancient China. However, no historical records describing the appearance...
Pulsed capacitively coupled plasmas (CCP) was applied to self-aligned-via (SAV) based all-in-one (AIO) etching process. Effects of bias and synchronous pulsed plasmas on the AIO etching process were analyzed to improve the reliability and reduce the RC delay in back-end-of-line (BEOL) copper interconnect system. For steps of hard-mask open and partial via etch, synchronous pulsed plasmas were applied...
This paper presents a novel concept of swarm robots, which mostly emphasizes on organization structure, rather than merely the quantity. A novel task-oriented swarmrobotic system (SociBuilder system) that is self-reconfigurable and supports self-assembly is introduced. The system simulates human labor division and social organization structure, thus it could represent human construction activities...
A complete speech model can improve performance for many speech applications. Probabilistic Acoustic Tube (PAT) is a probabilistic generative model of speech that has been shown potentially useful in a number of speech processing tasks. A point missing in previous PAT models is that they overlook AM/FM effect in voiced speech, which is in fact common and non-negligible. In this paper, we significantly...
Because of the local deformation of SAR images Registration of Multiband SAR images with high accuracy(sub-pixel accuracy) is a very difficult problem. This paper present an automatic Coarse-to-Precise(global-to-local) subpixel registration framework to track it. Firstly, affine SIFT method is adopted to get affine parameter of global transformation between registered images. After global registration,...
As a promising technique to obtain optimal degree of freedom (DoF) on multi-user wireless communication systems, interference alignment (IA) has been studied extensively in recent years. The most effective approach of IA is to deploy optima linear transceiver by exploiting spatial characteristics of wireless channels, and it is evaluated in measured multi-input multi-output (MIMO) interference channels...
In this paper, a partially decoding scheme, combined with the rate compatible Raptor-like low-density parity-check (LDPC) codes, is proposed to provide more robust, power saving solutions for the future terrestrial broadcasting systems. Different from the existing works, the proposed algorithm uses the least information in the codeword and stops immediately after the decoding is successful. We illustrate...
HDFS (Hadoop Distributed File System) is the popular file system. But HDFS has inefficient issue with small files. Traditional method has the drawback of high resource consumption and low efficiency performance. In order to resolve this problem, this paper proposes a novel approach for small files process, which works as an engine independent with the HDFS. This engine can reduce the overhead of HDFS...
Secure localization in wireless sensor networks (WSNs) has received a great deal of attention with the increasing applications of wireless sensors. Security issues of localization in WSNs need to take into account attacks from both external and internal nodes. In this paper, we propose a secure localization scheme based on trust evaluation called trust based secure localization (TBSL) to evaluate...
This paper puts forward a method for optimizing production cost of a special kind of production with randomicity. This method transforms stochastic optimization into a determinable one. It has two steps: first, by the means of mean production efficiency, the problem is transformed into a discrete variate optimization one without randomicity; second, by the means of penalty function method, the discrete...
Our aim in this paper is to introduce and study the new type of fuzzy ideals of a ring called generalized fuzzy imaginary right (resp. left) ideals and the direct products of them. The equivalence relation of them is given, besides, the properties of their intersection, union and level sets are discussed. Finally, we also give the properties of their homomorphic preimage.
In this paper, we introduce the definitions of anti-generalized fuzzy subring and generalized anti-fuzzy subring. Some fundamental properties of them are discussed. Finally, we also give the properties of their homomorphic image and homomorphic preimage.
Structural Relation Patterns (SRPs) mining is proposed for mining relations among sequences, these relations are generally hidden behind sequential patterns. Concurrent Sequential Pattern (CSP) and Exclusive Sequential Pattern (ESP) are two important parts of SRP, called Structural Relation Sequential Pattern (SRSP). Upon the previous researches, the concepts of SRSP are redefined; the properties...
How to accurately predict traffic data with weak regularity is difficult for various forecasting models. In this paper, least squares support vector machines (LS-SVMs) are proposed to deal with such a problem. It is the first time to apply the technique and analyze the forecast performance in the field. For comparison purpose, other three baseline predictors are selected because of their effectiveness...
