The Impact of Perceived Visual Complexity, Gender, and Cognitive Style on Children's Aesthetic Preferences for Learning Web Pages
Authors: Wang Hsiu-Feng , Wang Pei-Yu , Liao Ching-Chih , Lin Yu-Yin
Published: August 2014

This chapter examines children's aesthetic preferences for learning Web pages designed for them. It applies Berlyne's theory of aesthetic preference to these Web pages: a theory that suggests that people prefer a medium level of stimuli to a low or high level of stimuli. The experiment employs a 3 x 2 x 2 between-subject design; it explores perceived visual complexity, gender, cognitive style, and aesthetic preference. A total of 120 children (60 boys and 60 girls) aged between 11 to 12 years-old take part in the experiment. The children are asked to rate learning Web pages of different levels of perceived visual complexity for aesthetic preference. These Web pages have been created by the authors. The results of the experiment show that overall the children prefer Web pages that display a medium level of perceived visual complexity to those that display a high or low level of perceived visual complexity. Thus, the results support Berlyne's theory. However, when aesthetic preference is analysed with respect to gender, it is found that different levels of perceived visual complexity have an impact on boys' aesthetic preferences but not girls'. In other words, Berylne's theory is only partly supported. Likewise, Berylne's theory is only partly supported when aesthetic preference is analysed with respect to cognitive style. Here, imagers prefer a high level of perceived visual complexity and verbalisers prefer a medium level of perceived visual complexity. This chapter should be of interest to anyone who designs learning Web pages for children.
Change Management
Authors: Kogetsidis Harry
Published: August 2014

The rate with which change occurs has increased dramatically over the years. At the same time, the change management literature is full of claims about the high failure rate of change implementation programmes in organisations. In this position paper a case is made that change initiatives frequently fail because they are not holistic in nature. The paper argues that change can be managed more effectively if the various interconnected and interacting elements of the system are identified, the divergent interests of the various stakeholders are recognised, and the entire change process is managed systemically. As the failures of change efforts are commonly related to human issues, as opposed to technical factors, involving all stakeholders in the change process is expected to reduce resistance and to create a higher level of psychological commitment among employees towards the proposed change. The paper then looks into the implications that this holistic way of thinking has for information systems development and argues that information systems should not be implemented as a means to solving a problem but instead be treated as a significant tool to help address a complex mix of organisational issues. Information system strategy must be in line with the organizations’ corporate strategic plan and information systems must be related to a continually changing organisational context and a turbulent business environment.

Image Processing Algorithm Based on Solitary Wave
Authors: Zhu Zi Min , Liu Rong Qiang , Cao You Wei , Liu Fen Fen
Published: August 2014

The core algorithm of digital image processing has mainly involved three aspects: random theory, wavelet analysis and partial differential equations. This paper presents a new algorithm, which takes the digital image as a pixel grid, and then establishes the dynamic equation that has solitary wave solutions. Moreover, the solution can become analytic so it can be applied to the image directly. Meanwhile, due to the elastic collision properties of the solitary wave, pixel of the same size can produce the same kind of solitary wave, which facilitates a further processing of pixel. The interplay between pixels can be further studied in terms of collision property on account of the nonlinear effect. Analysis of the algorithm shows that solitary wave amplitude characterizes the effect between adjacent pixels, and the phase change of solitary waves provide the azimuth information of image.

Authors: Xu Mao Tong
Published: August 2014

In VSF-OFCDM wireless communication, wireless channel is divided into component channels with the same frequency space according to the frequency, and the carriers on component channels are mutually orthogonal. When there are enough subcarriers, the bandwidth efficiency of the system is close to nyquist limit, which can ensure the utilization ratio of system frequency. Therefore, under the premise of ensuring orthogonal division of channels, the channels received a secondary division according to data rate requirements and power limit of business to make the frequency resource fully used and makes the total power minimal, which realizes the optimal distribution of wireless-communication system resources.

Highway Alignment Parameters Design and Capacity Analysis on Two-Lane Highway
Authors: Liu Jiang
Published: August 2014

A two-lane highway is an undivided highway with only one lane of traffic in each direction. Two-lane highways are one of the most common roadways at mountainous areas in China. Due to the wider range to choose the horizontal and vertical curves in the design of two-lane highways, the combination of both leads to larger differences on two-lane highway capacities. Thus, the highway alignments are one of the key factors which affect the two-lane highway capacities. According to the empirical data and existing studies, it is regarded that there is no impacts on the capacity for horizontal curves with a radius more than 400m and vertical curves with the gradient less than 3%. Two concepts are defined as effective bending and effective gradient which represent the extent the horizontal curve bends and the steepness of vertical curve respectively. The method to calculate effective bending of horizontal curve and steepness of vertical curve is given and its relevant properties are also discussed. According to the simulation results and the principle of speed differences, the effective bending and effective gradient have been classified into 7 and 6 levels, separately. As a result, there will be 42 combinations of different highway alignments of two-lane highways based on the different combinations of the effective bending and effective gradient. Under this circumstance, the relationship of speed-volume and volume-PTSF (percent time spend following) are obtained from the simulation results. Finally, the capacity of two-lane highway is given under different highway alignments of two-lane highway at mountainous areas in China.

Authors: Zhan Wei Ming , Wang Jia
Published: August 2014

In order to solve the problem of single-phase ground fault classification, phase plane method is used. We use phase plane method to analysis single-phase ground fault waveform data first, so a series of discrete points is getting. The discrete points are divided by region on the phase plane to statistics the numbers in each region, so these numbers constitute the feature vector what we required. Use nearest neighbor classification method to achieve single-phase ground fault data classification. Empirical results show that this method can divided the faults into five to find fault reason, thereby improving the diagnostic capability of fault status and fault reason in distribution network.

Authors: Cong Hai Fang
Published: August 2014

In order to obtain high dynamic RMS performance of the scanning mirror in the working condition, the topology optimization method based on the constrain of dynamic deformation was carried out. Effective simplifications are implemented to reduce the complexity of the calculation. With the topology method, a lightweight form of the scanning mirror was generated on the dynamic working condition. The result shows that the lightweight ratio of the optimized structure is 47.4%, the PV value is 19.36nm and the RMS value is 5.65nm, which is improved by 18.46% and 17.41%, respectively. Besides, the first order frequency has increased by 113.8Hz. The results illustrate that the proposed method for the optimization of the scanning mirror is reasonable and practically.

Published: August 2014

Localization is a criticalissue for autonomous vehicle navigation. A localization model based on thestable response in lateral dynamics of the vehicle is hard for practicalapplication because of its nonlinearity, multidimensionality and multivariable.A dynamic self - adaptive network, which is able to adjust the scale of theparameters dynamically and has a good regression performance and self learningability, is used as a approximator to modeling the localization of the vehicle.In order to get a higher accuracy in modeling, a Kalman filer is designed forthe input signal such as steering angle and velocity. From the practicaltesting results on our vehicle, it’s indicated that the localization error is less than 1meter. So, the proposed method in this paper is a practicable and efficient onefor application.
