Chinese government has transformed the function of economy-construction-type to public-service-type under the guidance of scientific concept of development. The transformation of government functions undoubtedly require public spending structure also make corresponding changes. The purpose of the paper is to identify and verify what changes have taken in public expenditure structure of Fujian province...
Using 1-min transaction data, this study investigates the relationship between volume and volatility in CSI 300 futures market in China. Unit root test indicates that return series are stationary. LB-Q and ARCH-LM statistics confirm volatility clustering and time-vary volatility. ARMA (2, 2)-EGARCH (1, 1) model find evidence of GARCH effect, and positive shocks have a greater impact on volatility...
Phase Correlation is a well-known method for registration of images that are related by similarity transforms. Its extension to registration of affine transformed images is not straightforward. This paper presents a method for recovering the transformation parameters of images that have been translated, shifted, rotated and arbitrarily sheared. It is effective for recovering shearing parameters with...
Two classes of optimum frequency hopping sequences (FHSs) derived from Fermat quotient with respect to the Lempel-Greenberger bound are presented. The constructed p2-periodic sequences are defined over ℤp and have the maximum Hamming autocorrelation p, where p is a prime. Also, we give a new optimum family of sequences with size p. Moreover, we interpret the constructed sequences in terms of new partition...
In this paper, a novel design scheme for radar signal is proposed. It is based on a modification of Costas codes design obtained by increasing the frequency separation of frequency hops beyond the orthogonality condition. This condition states that frequency separation between frequency hops should be at most equal to the inverse of bit duration of the code. Indeed, increasing frequency separation...
Using large number of antennas at base station (BS) to formulate a multi-user multiple-input multiple-output (MU-MIMO) system, i.e., the massive MIMO, has attracted more and more attention recently, due to the high spectrum and energy efficiency it has. When there is correlation and mutual coupling, Rusek et al. showed that the channel may lose asymptotic orthogonality as the number of antennas increases...
When two signals or images to be correlated or convolved are of different sizes, overlap-add (OLA) and overlap-save (OLS) algorithms are often employed to reduce computational complexity. In this paper, we investigate the use of these algorithms for multidimensional correlations required in many image and video matching applications. In contrast to conventional wisdom, we show that OLA is more computationally...
In the current highly competitive environment of the NAND Flash/NVM/NOR flash market, cycle times (CT) are the key to success. CT performance depends on process time reduction, tool set (group of similar tool running same operations) performance, and WIP (Work In Process) management policy, but mainly on factory (fab) loading. Understanding factory CT variability is critical to meet customer commitments...
Multi-label classification problem has emerged rapidly from more and more domains as the popularity and complexity of data nature. In this work, we proposed a framework that can solve multi-label classification problems that either there exist constraints among labels or not. Under this framework, the multi-label classification problem can be modeled as a minimum cut problem, where all labels and...
Stereoscopic Warehouse plays an important role in the modernization of the logistics field. It is characterized by an informatization, automation, high efficiency, and often used in regional distribution center. In some special occasions or due to special field, the stereoscopic warehouse must be with tandem storage space in the reason that putting all of the racks parallelly in a single storage requires...
This paper uses the Chinese GEB IPO data from October 2009 to December 2012 to shed light on the autocorrelation of both initial returns and price update and the relations between the initial returns and price update. We find that both initial returns and price update are cyclical. These two variables are positively related. The equal-weighted average monthly initial returns are significantly positive...
Leadership styles and induced conflicts are essential to an enterprise and its performance; therefore, it is of paramount significance to study the impacting mechanism of leadership and conflicts on new ventures' performance. By building an intermediation model with three variables of conflicts, leadership styles and new venture performance, a study was conducted on the intermediation of different...
Based on the framework of non-parametric approach, the new jump variance and continuous sample path variance are constructed and the jump variance is modeled by combining A-J jump detection statistic. With high frequency data from Shanghai composite index, the empirical analyses are carried out from four aspects: the characteristics and contribution of jump variance, jump sizes and the relationship...
In order to consider the effect of slotting allowances on suppliers and consumers fully, we build a complete information dynamic game model. In the model, slotting allowances includes two parts, one part is the one-time payment and another part is changing with production. After analyzing the participants' decision-making in three kinds of downstream market with perfectly competitive market, monopoly...
In this paper we introduce the optimal odd-period binary Z-complementary pairs (OB-ZCPs), which display properties similar to Golay complementary pairs. These pairs have the maximum possible zero-correlation-zone (ZCZ) of width (N + 1)/2, where N denotes the sequence length, and the minimum possible magnitude of 2 for each out-of-zone aperiodic auto-correlation sum. Furthermore, we show that the optimal...
The noisiness of a channel can be measured by comparing suitable functionals of the input and output distributions. For instance, if we fix a reference input distribution, then the worst-case ratio of output relative entropy to input relative entropy for any other input distribution is bounded by one, by the data processing theorem. However, for a fixed reference input distribution, this quantity...
Scalability to large numbers of classes is an important challenge for multi-class classification. It can often be computationally infeasible at test phase when class prediction is performed by using every possible classifier trained for each individual class. This paper proposes an attribute-based learning method to overcome this limitation. First is to define attributes and their associations with...
In this paper, we present a no-reference image quality assessment method, which we call BNB (an acronym for Blurriness, Noisiness, Blockiness). Our BNB method quantifies blurriness, noisiness and blockiness of a given image, which are considered three critical factors that affect users' quality of experience (QoE). The well designed BNB metrics are based on the observation that the difference between...
In this paper, fundamental methods are proposed to model the multipath power-delay profile of frequency selective wireless channels with the focus on Digital Audio Broadcasting (DAB/DAB+/DMB). Beside the well known specifications COST 207 [1] and EN 50248 [2], there exist additional channel profiles for hilly regions with longer echoes especially for DAB, which are not covered in this two standards...
Orthogonal waveform design is quite an important issue for waveform diversity systems. A chaos based method for orthogonal discrete frequency coding waveform (DFCW) design is proposed in this paper to overcome the insufficient orthogonal waveforms and their finite coding length. Correlation properties of the designed signals are analyzed. Premises for chaos choosing and frequency quantification method...
