Abstract

The chapter reviews recent evidence of, and debates about, the integration of art, entertainment, and media in media portrayals (e.g., movies, photographs, theater, music, performance art, museums, story-telling, modifications of an environmental space, social media, painting, comics, dance, videogames, etc.) of climate change based on three sources of data: 1) articles listed in academic reference databases and Google Scholar, 2) online sites, and 3) climate change news images. 1) Retrieved articles discuss both the potential and challenges of communicating about climate change through art, entertainment, and media. However, research is inconsistent on and in some cases is critical of the nature and extent of effects of art-based climate communication. 2) The Internet is a rich and diverse source of websites and videos about climate change. We analyzed 49 sites based on the art medium or form discussed, the primary content related to climate change, and the apparent goal of the site or video. The most frequent goals were promote action, collaboration, raise awareness, climate change communication, discussion, empowerment, reshape public perception, and engagement. 3) Based on the major themes and frames identified through content and cluster analysis of 350 images associated with 200 news articles from 11 US newspaper and magazine sources through late 2009, we summarize the theme of art and mass media representations of the environment, and how those are associated with the other major themes. We conclude by suggesting promising areas for future research on the intersection of art and science in communicating about climate change.

Abstract

Purpose

Detecting objects in images and videos is a difficult task that has challenged the field of computer vision. Most of the algorithms for object detection are sensitive to background clutter and occlusion, and cannot localize the edge of the object. An object's shape is typically the most discriminative cue for its recognition by humans. The purpose of this paper is to introduce a model‐based object detection method which uses only shape‐fragment features.

Design/methodology/approach

The object shape model is learned from a small set of training images and all object models are composed of shape fragments. The model of the object is in multi‐scales.

Findings

The major contributions of this paper are the application of learned shape fragments‐based model for object detection in complex environment and a novel two‐stage object detection framework.

Originality/value

The results presented in this paper are competitive with other state‐of‐the‐art object detection methods.

The purpose of this paper is to focus on the accurate and steady control on trajectory tracking for wafer transfer robot, suppress the vibration and reduce the contour error.

Abstract

Purpose

The purpose of this paper is to focus on the accurate and steady control on trajectory tracking for wafer transfer robot, suppress the vibration and reduce the contour error.

Design/methodology/approach

The wafer transfer robot dynamic model is modeled. Through analyzing the characteristics of wafer transfer robot, cross‐coupled synchronized control is proposed based on the contour error model in task space to improve synchronization of the joints; the shaping for the joints by input shaper in task space is applied to suppress the vibration of the end effector during trajectory tracking. Then combining the cross‐coupled synchronized control with input shaping is proposed to improve accuracy and suppress the vibration.

Findings

The combination of cross‐coupled synchronized control and input shaping control method can improve the contour accuracy and reduce the vibration simultaneously during trajectory tracking. And the control method can be used to control the trajectory of wafer transfer robot.

Research limitations/implications

The transfer station is in the center of the robot body. When the transfer station may deviate from the center of the robot body, the synchronizing performance of three axes on the same plane must be considered.

Practical implications

The proposed method can be used to solve the vibration and synchronizing performance problems on similar SCARA robots in semi‐conductor and liquid crystal display industry.

Originality/value

The proposed control method takes advantage of the cross‐coupled synchronized control and input shaping control method. This combination has improved contour accuracy and reduced vibration than applying other methods, and it has achieved better performance than using single one control method only.

Abstract

Purpose

The purpose of this paper is to present a distance accuracy-based industrial robot kinematic calibration model. Nowadays, the repeatability of the industrial robot is high, while the absolute positioning accuracy and distance accuracy are low. Many factors affect the absolute positioning accuracy and distance accuracy, and the calibration method of the industrial robot is an important factor. When the traditional calibration methods are applied on the industrial robot, the accumulative error will be involved according to the transformation between the measurement coordinate and the robot base coordinate.

Design/methodology/approach

In this manuscript, a distance accuracy-based industrial robot kinematic calibration model is proposed. First, a simplified kinematic model of the robot by using the modified Denavit–Hartenberg (MDH) method is introduced, then the proposed distance error-based calibration model is presented; the experiment is set up in the next section.

Findings

The experimental results show that the proposed calibration model based on MDH and distance error can improve the distance accuracy and absolute position accuracy dramatically.

Originality/value

The proposed calibration model based on MDH and distance error can improve the distance accuracy and absolute position accuracy dramatically.

The purpose of this paper is to present a control system for a heavy duty industrial robot, including both the control structure and algorithm, which was designed and tested.

Abstract

Purpose

The purpose of this paper is to present a control system for a heavy duty industrial robot, including both the control structure and algorithm, which was designed and tested.

Design/methodology/approach

An industrial PC with TwinCAT real‐time system is chosen as the motion control unit; EtherCAT is used for command transmission. The whole system has a decoupled and centralized control structure. A novel optimal motion generation algorithm based on modified cubic spline interpolation is illustrated. The execution time and work were chosen as the objective function. The constraints are the limits of torque, velocity and jerk. The motion commands were smooth enough throughout the execution period. By using the Lagangue equation and assumed modes methods, a dynamic model of heavy duty industrial robots is built considering the elastic of both joints and links. After that a compound control algorithm based on singular perturbation theory was designed for the servo control loop.

Findings

The final experimental results showed that the control commands and algorithms could easily be calculated and transmitted in one sample unit. Both the motion generation and servo control algorithm greatly improved the control performance of the robot.

Research limitations/implications

All parts of the control algorithm can be computed on‐line except the optimal motion generation part. The motion generation part is time consuming (about 2.5 seconds), which can only be performed off‐line. Hence future work will focus on improving the efficiency of this algorithm; therefore it could be performed online, increasing the robot's overall robustness and adaptability.

Originality/value

Aiming at the internal and external causes that limit the dynamic performance of heavy duty industrial robots, this paper proposes a realizable scheme of control system and includes both the control structure and algorithms. A novel optimal motion generation algorithm is presented.

The purpose of this paper is to investigate oxidation and the Au‐Sn reaction of laser reflowed (LR) micro‐solder joints when different protective atmospheres were applied.

Abstract

Purpose

The purpose of this paper is to investigate oxidation and the Au‐Sn reaction of laser reflowed (LR) micro‐solder joints when different protective atmospheres were applied.

Design/methodology/approach

A N2 atmosphere at room temperature, 60°C, 100°C and 130°C, or an air atmosphere at room temperature were utilized in this study. The solder balls were composed of Sn‐2.0Ag‐0.75Cu‐3.0Bi, and 120 μm in diameter. The surface finish of one pad of the joints was 4.0 μm Au/0.1 μm NiFe/0.01 μm Ta, another pad was made of Cu plated with 3.0 μm Au. The laser reflow process time was controlled to within 10 ms. Auger Electron Spectroscopy (AES) was used to identify the oxidation condition of LR solder joints with or without protection from a N2 atmosphere at room temperature. The appearance and cross‐sections of the joints protected by a N2 atmosphere at different temperatures were evaluated using SEM analysis.

Findings

Oxidation of LR solder joints from an air atmosphere was extremely severe, and the surfaces of solder were rough as compared with joints protected by a N2 atmosphere. Au‐rich phases and needle‐like AuSn4 intermetallic compounds (IMCs) formed at the interfaces of the solder and the pads. As the temperature of the N2 atmosphere was increased above 100°C, almost all of the Au‐rich phases disappeared. More needle‐like AuSn4 IMCs formed at the interfaces, as compared with that in joints protected by a N2 atmosphere at room temperature and 60°C. In addition, the orientation of the IMCs had clearly changed.

Originality/value

The results may provide a guide for controlling oxidation and the Au‐Sn reaction of micro‐solder joints during the LR process, and improving the properties of joints between solder and pads with Au surface finishes, by regulating the protective atmosphere.

Abstract

Purpose

This paper's aim is to compare and contrast two ancient philosophies to determine their contribution to leadership. Fresh aspects to inclusiveness and resilience in leadership are to be examined.

Design/methodology/approach

The paper uses a conceptual analysis as the basis for future empirical testing. The respective contribution of Sun Zi's Art of War and the Bhagavad Gita to academic and practitioner literature is examined before key traits on leadership that are common in both documents are collated. These features are then investigated on their practical application to business. Based on the research gaps and shortcomings identified, new areas for further research are recommended.

Findings

These two ancient texts have contrasting ideas, yet there are areas of complementarity to suggest that Indian and Chinese leaders can learn from each other.

Research limitations/implications

Future research may explore how in different forms of ownership including joint ventures or host country operations the perspectives of leadership can impact on the behaviour of managers towards employees of a different culture.

Practical implications

Both Chinese and Indian cultures are growing in importance. This paper helps leaders from each culture to better understand the different mind‐sets.

Originality/value

Previous research has focused on the contrasts whereas this research focuses on the synergies between the Art of War and the Bhagavad Gita.

Abstract

Purpose

The purpose of this paper is to study the dynamic features of friction coefficient during running-in state based on recurrence analysis, so as to recognize the running-in state of crankshaft journal bearings.

Design/methodology/approach

The friction coefficient was measured in the friction experiments and the dynamic features are analyzed by recurrence plots (RPs), unthreshold recurrence plots (URPs) and recurrence quantification analysis.

Findings

During the running-in process, RPs have gone through disrupted patterns, drift patterns and homogeneous patterns successively. URP shows that the phase trajectory spirals in the disrupted pattern gradually converge in the drift pattern and remain stable in the homogeneous pattern. Three independent measures, recurrence rate, entropy and laminarity, are chosen to characterize friction coefficient from the perspective of point, diagonal line and vertical line structures of the RPs.

Originality/value

The results provide a feasible way to monitor the running-in process and recognize the running-in state.

Abstract

Reports the results of an attempt to relate the military treatise of the ancient Chinese strategist Sun Tzu to strategic quality management. Two sets of 20 statements were compiled, one from the work of Sun Tzu and the other from the concepts of strategic quality management. A group of employees experienced in quality management was then asked to indicate on a discrete scale the relevance of each statement in terms of its applicability on quality management. The rankings and correlations of the statements are presented and discussed. The results indicate a degree of relevance of Sun Tzu’s insights to strategic quality management in an Asian context.
