3D vision based quality inspection with computational intelligence
Authors: Yu Quan , Wang Kesheng 
Published: July 2013

PurposeProduct quality inspection is of importance in manufacturing industries to ensure that low quality or unqualified products are not delivered to the consumer. Human inspection has many limitations such as low accuracy or speed due to factors such as tiredness and boredom. Traditional 2D vision inspection also has limitations of product shape complexity or flexibility. Thus, automated 3D vision inspection is anticipated to meet the requirements of higher applicability. This paper seeks to address these issues.Design/methodology/approachIn many product quality inspection problems, geometrical parameters of the industrial parts are commonly used as the basis of quality inspection. Machine vision is widely applied to acquire such kind of parameters. Comparing to traditional 2D vision, 3D vision can acquire 3D coordinates of the object directly, so that the inspection can be accomplished which is difficult to do with 2D vision. As an active vision technique, structure light system (SLS) is applied to acquire the 3D coordinate information of inspected object in this paper. On the basis of point cloud and regression analysis, features relative to quality are defined and extracted as the attributes for the product classification. Three data mining techniques are applied to accomplish the classification in this paper, which include decision trees, artificial neural networks and support vector machine.FindingsA new intelligent automated 3D vision quality inspection for assembly lines has been developed, which comprises structure light system (SLS) and data mining approaches such as decision tree, artificial neutral networks and support vector machine.Originality/valueThe combination of structure light system (SLS) and data mining approaches makes the automated quality inspection available. The proposed system is easy to be implemented and flexible for different types of products.

Authors: Yixiong Feng , Yicong Gao , Zeyu Mai , Jianrong Tan 
Published: July 2013

PurposeExisting models of product assembly scheme design often ignore the constraint relations among design thinking. In order to grasp the functions of each part and the constraint relations among them in product assembly system macroscopically, further design and variation of product assembly system should be made according to design thinking. This paper seeks to address these issues.Design/methodology/approachThrough analyzing the similarity between biological organization system and product system and taking biology knowledge for reference, product assembly system was expressed as product function gene, product constraint gene, product function protein, product constraint protein and product cell and so on in this paper. The product gene model composed of product function gene groups and constraint genes was established and a modeling method based on it was proposed.FindingsThe author applied this method to model the 5‐DOF manipulator of complex diamond manufacturing special equipment with good results which proved the effectiveness of this modeling method.Originality/valueBy identifying constraint relations and design thinking in the gene model, the system makes the modification process which is conducted by the designers automatically identified and varied to achieve computer‐aided design and assembly.

Authors: Ahmed Bazaz Shafaat , Abbas Nayyer , Bilal Saif Muhammad , Ahmad Nisar 
Published: July 2013

PurposeThis paper aims to present design and characterization of a micrograsping system which is capable of safely grasping micro‐objects.Design/methodology/approachThe proposed micrograsping system consists of novel MEMS based microgripper integrated with capacitive contact sensor (fabricated in standard micromachining process SOI‐MUMPs), sense electronics, a controller, high voltage actuation circuit and graphical user interface.FindingsDue to the improvement in the lateral comb‐drive design, the actuator requires low actuation voltages in the range of 0‐45 V. This requires a simple and low power actuation circuitry. Capacitive feedback control mechanism is used in the sensor to detect the contact between the jaws and micro‐object while providing high values of the capacitance.Practical implicationsThe designed sense electronics can sense the capacitance ranging from 0‐330 fF. Due to the availability of integrated contact sensor, objects ranging from 54 μm to 70 μm can be gripped safely with the applied maximum force of 220 μN at the tip of the gripper.Originality/valueThe performance of the microgripper, controller algorithm and associated electronics were experimentally quantified through the gripping of 65 μm sized human hair.
Looking into the future: Hofstede long term orientation versus GLOBE future orientation
Authors: Venaik Sunil , Zhu Yunxia , Brewer Paul 
Published: July 2013

PurposeThe purpose of this paper is to critically examine, theoretically and empirically, the two time orientation dimensions – long‐term orientation (LTO) and future orientation (FO) – in the national culture models of Hofstede and GLOBE, respectively.Design/methodology/approachFollowing Kluckhohn and Strodtbeck's past‐present‐future theoretical lens, the Hofstede LTO and GLOBE FO measures are analysed to understand the conceptual domain covered by these two dimensions. Next, the authors empirically examine the relationship of Hofstede LTO and GLOBE FO with secondary data from Hofstede, GLOBE, and the World Values Survey.FindingsThis paper shows that Hofstede LTO and GLOBE FO dimensions capture different aspects of time orientation of societies. In particular, Hofstede LTO focuses on past (tradition) versus future (thrift) aspect of societies, GLOBE FO practices capture the present versus future (planning) practices of societies, and GLOBE FO values reflect societal aspirations and preferences for planning.Research limitations/implicationsA specific implication of these findings is that the three dimensions of time orientation are not interchangeable since they represent different characteristics of societies. A wider implication for researchers is to ensure high level of precision in and congruence among construct labels, definitions and measures to avoid confusion and misapplication of cross‐cultural concepts.Practical implicationsIn an increasingly globalized world, a clear understanding of societal time orientation will help managers deal more effectively with their counterparts in other countries.Originality/valueThe key contribution of this paper is in identifying and clarifying, both theoretically and empirically, the anomalies in the labels, definitions and measurement of Hofstede long‐term orientation and GLOBE future orientation national culture dimensions. It also shows a useful way forward for researchers on how to use these national culture dimensions to explain other phenomena of interest to cross‐cultural scholars.
A comparative study of UK and Taiwanese chemical plant managers
Authors: Vickers David 
Published: July 2013

PurposeThe purpose of this paper is to compare the competencies of managers in the UK and Taiwan.Design/methodology/approachA comparative analysis of managers using a behavioural event interviewing (BEI) technique.FindingsBoth cultures were highly achievement focussed. However, there were several marked differences in other behaviours which appear to be cultural in nature. UK managers demonstrated more interpersonal awareness, and concern for impact, whereas Taiwanese managers were more likely to demonstrate critical information seeking behaviour.Research limitations/implicationsInterviews in some instances failed to uncover data and this has implications for the use of generic behavioural event interviews internationally.Practical implicationsThe research suggests the idea of organisations' employing generic “international” competency models and behavioural event interview techniques is problematic.Originality/valueThe research is able to demonstrate the problems with international competency models through unique access to an organisation's competency model and to managers in two locations.

Authors: Liu Songbo , Schuler Randall S. , Zhang Pengcheng 
Published: July 2013

PurposeThe purpose of this paper is to examine team external learning, particularly focusing on: how leader external learning behavior affects team external learning; how team external learning influences employee creativity; and whether team internal learning is a moderator between the cross‐level relationship of external learning and employee creativity in Chinese R&D teams.Design/methodology/approachSurvey questionnaire were administered to a sample of 80 R&D teams comprising 331 employees from three medium‐sized Chinese high‐tech companies. HLM was used to test cross‐level relationships.FindingsThe paper hypothesizes that: leader external learning positively influences team external learning; team external learning leads to employee creativity; and team internal learning moderates the relationship between team external learning and employee creativity. Results support hypotheses 2 and 3, but not hypothesis 1. In addition, leader external learning is found to positively influence employee creativity.Practical implicationsThis study has implications for both team leaders and top management. Although the context of this study is in Chinese R&D teams, all those teams facing similar environment to R&D teams can also learn from this study. There are several interesting implications for scholars who are studying teams, creativity and innovation.Originality/valueCombining fields of team learning, boundary spanning, creativity and leadership, the paper addresses the following four questions, and provides further insights to the area of team external learning: First, what is the cross level relationship between team external learning and employee creativity? Second, is internal learning a moderator on the relationship between team external learning and employee creativity in R&D project teams? Third, is leader external learning behavior one of antecedents of team external learning? Fourth, is there anything unique about team external learning in Chinese culture? The paper provides research evidence for each of these questions.

Published: July 2013

PurposeThe purpose of this paper is to address the subject of work attitude drivers within the current scenario considering two influencing factors, culture and generation. Both membership of a particular generation and membership of a particular culture can affect individuals' work attitudes. The study considers these two factors in order to analyse five dimensions that are sources of work attitudes: life project, professional ethics, and attitude towards authority, leadership and commitment to the company.Design/methodology/approachDrawing upon a sample of almost one thousand people from various Ibero‐American countries, the results show significant differences between generations and cultures, particularly when focusing on the life project.FindingsAmong its conclusions, the paper points out that Latin America cannot be viewed as a homogenous whole in terms of individual work attitude. On the contrary, it is characterised by a significant degree of national diversity and managers should take this into account when designing initiatives to improve employee motivation.Originality/valueThe contribution that this paper seeks to make is to include the cross‐cultural perspective in the study of attitudes towards work, which has received less attention in previous studies.
A dynamic portfolio theory model based on minimum semi‐absolute deviations criterion with an application in the Chinese stock markets
Authors: Chen Li , Pan Heping 
Published: July 2013

PurposeThe purpose of this paper is to prove the effectiveness of minimum semi‐absolute deviations (MSAD) method in dynamic portfolio investment.Design/methodology/approachIn financial investment, the classical static portfolio theory of Markowitz type lacks the dynamic adaptability to the changing market situations. This paper proposes a dynamic portfolio theory which uses MSAD criterion on a moving window to replace the Markowitz mean‐variance analysis.FindingsTwo specific models are developed to test the validity of the MSAD method: the first model constructs a portfolio consisting of Shanghai‐Shenzhen 300 Index and a national debt as two contrarian assets; the second model constructs a portfolio consisting of a complete set of 18 Chinese stock sector indices and a national debt. The empirical results of the test using six‐year monthly data (2005 to 2010) provide significant evidence that the MSAD method is valid, producing superior returns of investment over the stock index during the test period.Research limitations/implicationsThe findings in this study clearly highlight the validity of the MSAD method in determining the weights of assets in Chinese stock markets.Practical implicationsIn order to resolve the problem of portfolio investment in Chinese stock markets, the MSAD method with stop loss control strategy can be used for investors to obtain the weights of assets and control the risk.Originality/valueThis study analyzes and verifies the effectiveness of the MSAD method in dynamic portfolio investment. The stop loss control strategy designed and used in the MSAD method is a pioneering and exploratory experiment.
Innovative ICT‐mediated activities for people, profit and planet
Authors: Hasan Helen , Meloche Joseph 
Published: July 2013

PurposeSolutions to complex environmental problems rely on the innovative knowledge and expertise of many professions whose members accept their responsibilities towards the environment. The study described here canvases information systems (IS) professionals for their perspectives, knowledge and expertise within the domains of Green IT and Green IS.Design/methodology/approachFollowing a review of the Green IT and IS literature, two topics were identified for a Q‐study conducted among IS professionals: topic 1 focussed on which technologies, systems and applications offer the greatest opportunity in solving environmental problems, and topic 2 on what sets of issues affect these green opportunities. Activity Theory was used to interpret the factors emerging from the Q‐study.FindingsThree categories of activities were identified in topic 1 involving ICT support for “teleworking and teleconferencing”, “monitoring, optimising, and modelling” and “influencing human understanding and behaviour”. The topic 2 responses were quite varied.Research limitations/implicationsA Q‐study is both subjective and exploratory, not seeking consensus but rather the breadth of opinion on a topic. The findings of topic 1 indicate three directions for future research and topic 2 identified many issues to consider in pursuing Green outcomes.Practical implicationsThe three topic 1 categories of activities identify practical “green” applications of ICT.Social implicationsThe varied issues identified from topic 2 reveal the interconnection of environmental projects with economic and social issues.Originality/valueFollowing this study of IS professional the authors call on other professions to apply the expertise of their respective fields to the environmental cause.
Innovative employee behaviour
Authors: Bysted Rune 
Published: July 2013

PurposeOrganizational performance is positively affected by employees’ innovative behaviour, but recent studies indicate that innovative work behaviour may have negative performance consequences. Negative tensions may arise due to employees’ different views on innovation, and efficiency may be reduced because of high job autonomy in innovative job settings. This study aims to examine how job satisfaction and mental involvement via moderation effects increase the effectiveness of innovative work behaviour.Design/methodology/approachA theoretical model was developed and tested on panel sample data representing 294 employees in a Danish financial company. The response rate on the survey was 93 per cent. The data was analysed via confirmatory factor analysis and hierarchical regression models.FindingsThis study shows that job satisfaction and innovative work behaviour can be aligned in environments characterized by innovation trust. Further mental involvement is identified as a component increasing innovative work behaviour in situations without the opportunity for monitoring.Practical implicationsFrom a managerial perspective: the alignment of job satisfaction and innovative behaviour is central, as this joint optimization affects organizational performance positively.Originality/valueThis study reports one of a very limited number of studies focusing on the negative effects of innovative work behaviour. This study demonstrates that innovation trust aligns job satisfaction and innovative work behaviour, and further that mental involvement increases the efficiency of job autonomy.
Effects of the scalar parameters in the Suzen‐Huang model on plasma actuator characteristics
Authors: Halimi Bin Ibrahim Imran , Skote Martin 
Published: July 2013

PurposeFor the past decade, plasma actuators have been identified as a subset in the realm of active flow control devices. As research into plasma actuators continues to mature, computational modelling is needed to complement the investigation of the actuators. This paper seeks to address these issues.Design/methodology/approachIn this study, the Suzen‐Huang model is chosen because of its ability to simulate both the charge density and Lorentz body force. Its advantages and limitations have been identified with a parametric study of two constants used in the modelling: the Debye length (λD) and the maximum charge density value (ρc* ). By varying the two scalars, the effects of charge density, body force and induced velocity are examined.FindingsThe results show that the non‐dimensionalised body force (Fb*) is nonlinearly dependent on Debye length. However, a linear variation of Fb* is observed with increasing values of maximum charge density. The optimized form of the Suzen‐Huang model shows better agreement in the horizontal velocity profile but still points to inaccuracy when compared to vertical velocity profile.Originality/valueThe results indicate that the body force still has to be modelled more extensively above the encapsulated electrode, so that the horizontal and vertical components of induced velocities are accurately obtained.
Homotopy analysis method for space‐time fractional differential equations
Authors: Zhang Xindong , Wei Leilei , Tang Bo , He Yinnian 
Published: July 2013

PurposeIn this article, the authors aim to present the homotopy analysis method (HAM) for obtaining the approximate solutions of space‐time fractional differential equations with initial conditions.Design/methodology/approachThe series solution is developed and the recurrence relations are given explicitly. The initial approximation can be determined by imposing the initial conditions.FindingsThe comparison of the HAM results with the exact solutions is made; the results reveal that the HAM is very effective and simple. The HAM contains the auxiliary parameter h, which provides a simple way to adjust and control the convergence region of series solution. Numerical examples demonstrate the effect of changing homotopy auxiliary parameter h on the convergence of the approximate solution. Also, they illustrate the effect of the fractional derivative orders a and b on the solution behavior.Originality/valueThe idea can be used to find the numerical solutions of other fractional differential equations.
A spatially adaptive grid refinement scheme for the finite element solution of a second order obstacle problem
Authors: Iqbal S. , Javed A. , Ansari A.R. , Siddiqui A.M. 
Published: July 2013

PurposeThe authors' objective in this paper is to find the numerical solutions of obstacle, unilateral and contact second‐order boundary‐value problems.Design/methodology/approachTo achieve this, the authors formulate a spatially adaptive grid refinement scheme following Galerkin's finite element method based on a weighted‐residual. A residual based a‐posteriori error estimation scheme has been utilized for checking the approximate solutions for various finite element grids. The local element balance has been considered as an error assessment criterion. The approach utilizes piece‐wise linear approximations utilizing linear Langrange polynomials. Numerical experiments indicate that local errors are large in regions where the gradients are large.FindingsA comparison of the spatially adaptive grid refinement with that of uniform meshing for second order obstacle boundary value problems confirms the superiority of the scheme without increasing the number of unknown coefficients.Originality/valueThe authors believe the work has merit not only in terms of the approach but also of the problem solved in the paper.
