Articulated arm coordinate measuring machine is a specific robotic structural instrument, which uses D-H method for the purpose of kinematic modeling and error compensation. However, it is difficult for the existing error compensation models to describe various factors, which affects the accuracy of AACMM. In this paper, a modeling and error compensation method for AACMM is proposed based on BP Neural Networks. According to the available measurements, the poses of the AACMM are used as the input, and the coordinates of (...) the probe are used as the output of neural network. To avoid tedious training and improve the training efficiency and prediction accuracy, a data acquisition strategy is developed according to the actual measurement behavior in the joint space. A neural network model is proposed and analyzed by using the data generated via Monte-Carlo method in simulations. The structure and parameter settings of neural network are optimized to improve the prediction accuracy and training speed. Experimental studies have been conducted to verify the proposed algorithm with neural network compensation, which shows that 97% error of the AACMM can be eliminated after compensation. These experimental results have revealed the effectiveness of the proposed modeling and compensation method for AACMM. (shrink)

Video surveillance plays a vital role in maintaining the social security although, until now, large uncertainty still exists in danger understanding and recognition, which can be partly attributed to intractable environment changes in the backgrounds. This article presents a brain-inspired computing of attention value of surrounding environment changes with a processes-based cognition model by introducing a ratio valueλof EC-implications within considered periods. Theoretical models for computation of warning level of EC-implications to the universal video recognition efficiency are further established. Imbedding (...) proposed models into the online algorithms is suggested as a future research priority towards precision security for critical applications and, furthermore, schemes for a practical implementation of such integration are also preliminarily discussed.

Aiming at the problem that the embedded platform cannot meet the real-time detection of multisource images, this paper proposes a lightweight target detection network MNYOLO suitable for embedded platforms using deep separable convolution instead of standard convolution to reduce the number of model parameters and calculations; at the same time, the visible light target detection model is used as the pretraining model of the infrared target detection model and the infrared target data set collected on the spot is fine-tuned to (...) obtain the infrared target detection model. On this basis, a decision-level fusion detection model is obtained to realize the complementary information of infrared and visible light multiband information. The experimental results show that it has a more obvious advantage in detection accuracy than the single-band target detection model while the decision-level fusion target detection model meets the real-time requirements and also verifies the effectiveness of the above algorithm.

Research on urban agglomerations from the perspective of network spatial structure is important to promote their sustainable development. Based on online and traditional data, this paper first improves three aspects of the traditional spatial gravity model—city quality, the gravitation coefficient, and city distance—considering urban center functional intensity and population mobility tendencies. The resulting improved directional gravity model is applied to analyze the structure of the city network for two urban agglomerations in China, the Beijing-Tianjin-Hebei urban agglomeration and the Yangtze River (...) Delta urban agglomeration. The results of the study are as follows: the existing urban connections have obvious hierarchies and imbalances, with the YRDUA urban hierarchical connections being of larger scale. Cities are closely connected, but city networks are unbalanced, though the YRDUA has more balanced urban development. Each node city has a clear radiation range limit, and spatial distance remains an important constraint on urban connections. The backbone network of the BTHUA has a triangular shape and trends toward a “sparse north and dense south,” while the YRDUA is characterized by multiple axes and an overall distribution that trends toward a “dense north and sparse south.” Cities with poor comprehensive strength are more likely to be captured, forming an attract and be attracted relationship. The BTHUA and the YRDUA each form three communities. (shrink)

ObjectiveThere is little literature on the validity of kurtosis-adjusted noise energy metrics in human studies. Therefore, this study aimed to validate the application of cumulative noise exposure adjusted by kurtosis in evaluating occupational hearing loss associated with non-Gaussian noise among manufacturing workers.MethodsA cross-sectional survey was conducted on 1,558 manufacturing workers exposed to noise from five industries to collect noise exposure and hearing loss data. Both CNE and kurtosis-adjusted CNE were collapsed into 2-dB∙year bins, and the mean noise-induced permanent threshold shifts (...) at 3, 4, and 6 kHz in each bin were calculated. The contributions of CNE and CNE′ to noise-induced hearing loss were compared using the multiple linear regression. The degree of overlap of two linear regression equations was used to evaluate the validity of the CNE′ using a stratified analysis based on age and sex.ResultsMultiple linear regression models showed that after kurtosis adjustment, the standardized regression coefficient of CNE increased from 0.230 to 0.255, and R2 increased from 0.147 to 0.153. The linear relationship between NIPTS346 and CNE′ or CNE showed that the regression line of non-Gaussian noise was closer to that of Gaussian noise when using CNE′ than using CNE. The mean difference in NIPTS346 between the equations of non-Gaussian noise and Gaussian noise was significantly reduced from 4.32 to 1.63 dB HL after kurtosis adjustment. Through a stratified analysis, these significant decreases were observed in male and female workers, and workers aged ≥30 years old.ConclusionAs a noise exposure metric combining noise energy and temporal characteristics, the kurtosis-adjusted-CNE metric was more effective than CNE alone in assessing occupational hearing loss among manufacturing workers in non-Gaussian noise environment. However, more studies are needed to verify the validity of the kurtosis-adjusted-CNE metric. (shrink)

The importance of ethical leadership in organizations has been increasingly recognized, especially as a shield against unethical employee behaviors and corporate misconducts. Ethical leadership has been theorized to include two aspects: “moral person” and “moral manager.” This conceptualization resonates well with Chinese teachings of Confucius on leadership and management—namely xiuji and anren. Based on the theoretical framework of ethical leadership, we develop and validate a new ethical leadership measure. Through qualitative studies and five quantitative studies, we establish the reliability and (...) convergent, discriminant, and predictive validities of the ELM in a Chinese context. In addition, using a US sample, we find that the ELM has partial measurement invariance across Chinese and American contexts. (shrink)

Workplace procedural justice is an important motivator for employee work attitude and performance. This research examines how procedural justice affects employee engagement. We developed three propositions. First, based on the group engagement model, we hypothesized that procedural justice enhances employee engagement through employee organizational identification. Second, employees with stronger moral identity centrality are more likely to be engaged in their jobs. Third, procedural justice compensates for the effect of moral identity centrality on employee engagement. Specifically, when procedural justice is higher, (...) employee moral identity centrality plays a less significant role in employee engagement; whilst when procedural justice is lower, the effect of moral identity centrality on employee engagement is stronger. Research findings based on an employee survey in a leading financial service organization provide support for the above propositions. (shrink)

We present a new proof for the standardization theorem in $\lambda$-calculus, which is largely built upon a structural induction on $\lambda$-terms. We then extract some bounds for the number of $\beta$-reduction steps in the standard $\beta$-reduction sequence obtained from transforming a given $\beta$-reduction sequence, sharpening the standardization theorem. As an application, we establish a super exponential bound for the lengths of $\beta$-reduction sequences from any given simply typed $\lambda$-terms.

This paper delves into a two-agent scheduling problem in which two agents are competing for a single resource. Each agent has a set of jobs to be processed by a single machine. The processing time, release time, weight, and the due dates of each job are known in advance. Both agents have their objectives, which are conflicting in nature. The first agent tries to minimize the total completion time, while the second agent tries to minimize the number of tardy jobs. (...) The two agents’ scheduling problem, an NP-hard problem, has a wide variety of applications ranging from the manufacturing industry to the cloud computing service provider. Due to the wide applicability, each variation of the problem requires a different algorithm, adapted according to the user’s requirements. This paper provides mathematical models, heuristic algorithms, and two nature-based metaheuristic algorithms to solve the problem. The algorithm’s performance was gauged against the optimal solution obtained from the AMPL-CPLEX solver for both solution quality and computational time. The outlined metaheuristics produce a solution that is comparable with a short computational time. The proposed metaheuristics even have a better solution than the CPLEX solver for medium-size problems, whereas the computation times are much less than the CPLEX solvers. (shrink)

To better understand the multiple individual factors that contribute to college cheating, we undertook a multivariate analysis of a national sample of 2,503 college students. Our findings indicated that demographic characteristics, character qualities, college experience, and student perceptions and attitudes are all significantly associated with academic cheating.

Due to the logical problems of unclear boundaries, staggered parallels, disordered standard, etc., existing in Jakobson’s intralingual, interlingual, and intersemiotic translations, the first triadic division of translation in terms of semiotics has been criticized since the 1980s. However, most of the previous semiotic research in China and the world at large still stays on the interlingual translation of literary texts, neglecting semiotic transformations as a sign activity and semiosis between tangible signs and intangible ones in the same and/or different period (...) of time, within the same ethnic culture or across the distinctive ethnic cultures. Hereby, it is necessary to refer to and redefine the term “semiosphere” introduced by Yuri Lotman in 1984 and the literatures after, to revise intrasemiospheric translation, intersemiospheric translation, and suprasemiospheric translation introduced in Jia. 31–46), and to elaborate on their nature, structure, content, and connotative significance. This is not only conducive to building translation semiotics as a subfield of general semiotics, but also to broadening the theoretical visions of applied semiotics and translation studies, and verifying the theoretical validity of general semiotics and translation semiotics in interpreting and explaining the semiotic transformations in translation as a special sign activity.

Auxin is a key regulator of plant developmental processes. Its effects on transcription are mediated by the AUXIN RESPONSE FACTOR (ARF) family of transcription factors. ARFs tightly control specific auxin responses necessary for proper plant growth and development. Recent research has revealed that regulated ARF protein accumulation and ARF nucleo‐cytoplasmic partitioning can determine auxin transcriptional outputs. In this review, we explore these recent findings and consider the potential for regulated ARF accumulation in driving auxin responses in plants.

How to improve the development quality of state-owned enterprises is of great significance to the economic and social development in the transition period. And promoting the reform of mixed ownership is an important path for state-owned enterprises to achieve high-quality development. Based on the micro-data of China’s A-share listed state-owned companies, the paper explores the impact of mixed ownership reform on the high-quality development of state-owned enterprises. It clarifies the importance and moderation of equity reform and the heterogeneity of impact (...) effects from the theoretical mechanism analysis and empirical test. It also analyzes the reasons of inverted U-shape from the perspective of the transmission mechanism of the internal competition atmosphere and non-state-owned capital speculation motivation. It is found that the relationship between equity reform and state-owned enterprises’ high-quality development is inverted U-shaped with multi-dimensional heterogeneity. From the analysis of conduction mechanism, on the one hand, the equity reform can enhance the internal competitive atmosphere, stimulate the vitality of enterprises and improve the development quality for state-owned enterprises. On the other hand, it enhances the speculation motivation of enterprises and slows down the high-quality development process. (shrink)

This article examines the mediation effect of brand identification and the moderating effect of service quality (SQ) on the effects of corporate social responsibility (CSR) association on service brand performance. A survey of customers of mobile telecommunications services was conducted. The study finds, first, that both CSR and SQ have direct effects on brand identification and customer satisfaction and indirect effects on customer satisfaction (via brand identification) and on service brand loyalty (via customer satisfaction and via "brand identification/customer satisfaction"). Second, (...) SQ enhances the effect of CSR on brand identification. This study contributes to the literature by incorporating three perspectives of service brand performance — CSR association, SQ, and brand identification - into one general framework that stresses (a) the mediating role of brand identification in predicting customer satisfaction and service brand loyalty; and (b) the interactive effect of CSR and SQ in predicting brand identification.

This book reinterprets classical Chinese philosophical tradition along the conceptual line of human dignity. Through extensive textual evidence, it illustrates that classical Confucianism, Mohism and Daoism contained rich notions of dignity, which laid the foundation for human rights and political liberty in China, even though, historically, liberal democracy failed to grow out of the authoritarian soil in China. The book critically examines the causes that might have prevented the classical schools from developing a liberal tradition, while affirming their positive contributions (...) to the human dignity concept. Analysing the inadequacies of the western concept of human dignity, the text covers relevant teachings of Kongzi, Mengzi, Xunzi, Mozi, Laozi and Zhuangzi (in comparison with Rousseau). While the Confucian notions of humanity (Ren), righteousness (Yi), and gentleman (Junzi) bear most directly on the conception of dignity, Mohism and Daoism provide salutary corrections to the ossification of the orthodox Confucian practice (Li).

Truth pluralism is the view that there is more than one truth property. The strong version of it (i.e. strong pluralism) further contends that no truth property is shared by all true propositions. In this paper, I help strong pluralism solve two pressing problems concerning mixed discourse: the problem of mixed inferences (PI) and the problem of mixed compounds (PC). According to PI, strong pluralism is incompatible with the truth- preservation notion of validity; according to PC, strong pluralists cannot find (...) any appropriate truth property for mixed compound propositions, whose atomic constituents are from different domains of discourse (e.g., <sky is blue and chocolate is tasty>). I argue that the strong pluralist is motivated to take the truth predicate in truth-involving universal statements to be deflationary to avoid the two pressing problems. Such a move entails that the truth predicate in the platitude of validity (V) for any argument, it is valid if and only if necessarily its conclusion is true when its premises are all true does not denote any substantive truth property. Instead, it is merely an expressive device to help people generalize instances of (V) to (V). Analogous stories hold for the truth predicate in the platitudes of compound (e.g., conjunction). The upshot is that, the strong pluralist can solve PI and PC by further conceding that mixed compounds are true/false in a deflationary way. (shrink)

Tianyi Zhang offers in this study an innovative philosophical reconstruction of Shihāb al-Dīn al-Suhrawardī's (d. 1191) Illuminationism. Commonly portrayed as either a theosophist or an Avicennian in disguise, Suhrawardīappears here as an original and hardheaded philosopher who adopts mysticism only as a tool of philosophical inquiry. Zhang makes use of Plato's cave allegory to explain Suhrawardī's Illuminationist project. Focusing on three areas-the theory of presential knowledge, the ontological discussion of mental considerations, and Light Metaphysics-Zhang convincingly reveals the (...) Nominalist and Existential nature of Illuminationism, and thereby proposes a new way of understanding how Suhrawardī's central philosophical ideas cohere. (shrink)
