The performance of Beidou MEO/IGSO satellite signal acquisition is greatly affected by the secondary code, the NH (Neumann-Hoffman) codes with possible bit sign transition in every millisecond modulated on the signal, which puts a limitation on the coherent integration duration. This paper address the problem of coherent integration over periods longer than one primary code length and the acquisition...
For Boolean functions computed by de Morgan formulas of sub quadratic size or read-once de Morgan formulas, we prove a sharp concentration of the Fourier mass on "small-degree" coefficients. For a Boolean function f: {0, 1}^nto {1, -1} computable by a de Morgan formula of size s, we show that [ sum_{Asubseteq [n]:, |A|>s^{1/Gamma + epsilon}} hat{f}(A)^2 leq exp(-s^{epsilon/3}), ] where...
For 21st century businesses, humans are the most critical factors to remain competitive [1]. However, the biggest challenge for human resources researcher is that how to inspire people's maximum potential, and combined human potential with organizational performance. The achievement motivation, emotional stability and communication motivation, which are the most important psychological characteristics...
Using a real case with 252 samples, we investigated the relationships among service integrators' power, service suppliers' relationship commitment, competitor network competence and service supply chain integration in service industry of South China. The empirical results revealed that service suppliers' relationship commitment mediated the relationship between service integrators' power and service...
This paper uses two generations products as an example to examine the pricing problem of multi-generation product when there're several kinds of customers in the market, and analyzes the effect of percentage of multi-generation product buyers and strategic customers on pricing new generation product and on discount price of old generation product. The study shows that the price of the new generation...
Generally speaking, the organizational citizenship behavior (OCB) of employees and the degree of organizational socialization play significant roles in job performance and employees' feelings. In this research, an empirical tracking study was conducted. First, two OCB dimensions were measured on campus. Second, four organizational socialization dimensions were measured in the workplace. Five months...
This article addresses trust in computer systems as a social phenomenon, which depends on the type of relationship that is established through the computer, or with other individuals. It starts by theoretically contextualizing trust, and then situates trust in the field of computer science. Then, describes the proposed model, which builds on what one perceives to be trustworthy and is influenced by...
Groups in organizations have become increasingly diverse over the years, but the impact may be positive or negative, and scholars do not have a clear answer. We mainly review the 2006–2013 literature on diversity and group performance to study more complex conceptualizations of diversity, especially in which part we suggest a new dimension that is diversity of members' relationship in the categorization...
Traditional OTA (Online Travel Agent) is challenged by the Internet and mobile business with the evolution of information. The precise forecasting of ticket sales in OTA companies is beneficial to budget control and service quality. The paper develops an integrated forecasting model by combining the internal factors immediately influencing the ticket sales and the external factors reflecting the ticket...
We present a deterministic version of our novel Monte-Carlo Regression based method MCReg [1] for transcriptome quantification from RNA-Seq reads. Experiments on simulated and real datasets demonstrate better transcriptome frequency estimation accuracy compared to that of the existing tools which tend to skew the estimated frequency toward super-transcripts.
In this paper, we propose an explicit signaling of RDPCM scheme for a lossy intra-coded block, and achieve a significant coding gain over the HEVC Range Extension reference software in the screen contents coding. We define three RDPCM modes, and transmit the side information so that the best RDPCM mode can be applied to residual signals after all available angular directional predictions. Contexts...
Extended power laws and inhomogeneous connections are structural patterns often found in empirical networks. Mechanisms based on the formation of triads are able to explain the power law behavior of the degree distribution of such networks. The proposed model introduces a two-step mechanism of attachment and triad formation that illustrates how preferential linkage plays an important role in shaping...
Recent generalisations of stochastic filtering methods to multi-object systems have become very popular for solving multi-target tracking problems over the last decade. However, there was previously no general means of introducing correlations between objects. In this article, we investigate generalisations of such multi-object filters for systems where there may be dependencies between objects. Determining...
Instructional activities should allow applying the knowledge acquired in the day by day and in real situations. Different studies evidence the potential impact of video games on learning, however very few empirical studies that focus on continuous assessment. On the other hand, because the variables that influence the achievement of learning objectives are different levels becomes complex to validation...
In recent years, few Chinese hospitals introduced operation mode named day surgery, This paper concerns that the introduction of day surgery has an impact on patients, we put forward a question whether carrying out day surgery will reduce waiting time for admission. This paper put forward a hypothesis: carrying out day surgery reduces waiting time for admission. We collect datum related to Laparoscopic...
Owing to the industry characteristics of civil servants which have special requirements on spirit of service and devotion, exploring the status quo and relationship of its workplace spirituality and organizational citizenship behavior makes a big difference to improve the capability and efficiency of government services. Through the survey of 468 civil servants in Beijing, the study found that the...
Proliferation of mobile phones over the last decade has led to innovative methods for studying social behavior and friendship patterns. Our present study combined advanced mobile phone technologies, such as Bluetooth scanning and automated pushing surveys, with self-reported questionnaires to examine the social structure and psychological well-being of college students. We distributed smartphones...
Malicious information like harassment, slander or bogus news is becoming a serious problem on social networking sites, and solving it requires profound insight into user behaviors of malicious and victim accounts. In this paper, we conduct a preliminary study on a whistleblowing network, constructed from 328472 whistleblowing (complaining) reports. To evaluate its efficiency, we perform a series of...
In order to study the variation rule of the physical-chemical indicators of Korla fragrant pear in the maturation process, and explore the correlation among these indicators, the fruit firmness, chlorophyll content, soluble solids content(SSC) and Vitamin C content were studied. Adopting to the methods of correlational analysis and regression analysis, the indicators mean and the correlation among...
In recent years, based on the steady-state visual evoked potential (SSVEP) brain-computer interfaces (BCIs) have generated significant interest, due to their shorter calibration times and higher information transfer rates. Target identification is the core signal processing task in BCIs. Power spectral density analysis (PSDA) and canonical correlation analysis (CCA) are the most popular and widely...
