Authors: Sørensen Christian Grund
Published: January 2014

The aim of this paper is to discuss the relationship between content, context and connectivity and suggesting a model of Dynamic Interplay. This is done in relation to a specific learning environment concerning cultural mediation, in casu the Kaj Munk Case of the EuroPLOT-project (an EU-supported research project under EACEA). In the development of this project several categories of content have been implemented in technology enhanced learning tools. These have been designed to support learning in different contexts and eventually the role of the connectivity of these learning objects and tools is discussed. Focus is here on The Kaj Munk Study Edition, The Conceptual Pond, Immersive Layers Design, and Generative Learning Objects (GLOs) which are applications affiliated with the Munk case. This paper explores the persuasive potential of the interplay between the different applications for the benefit of learning and reflection and a model of Dynamic Interplay is introduced. This is done with a primary inspiration from rhetoric particularly in the shape of the Aptum model and a focus on kairos. Possible benefits of this approach are discussed and several questions for further research are suggested.
Open Innovation in Entrepreneurships
Authors: Rahman Hakikur
Published: January 2014

Efforts have been given to gain knowledge from a meager collection of empirical studies on various taxonomies of innovation and their effects on open innovation strategies for the development of entrepreneurship, despite abundance of studies and researches that are available on the broader aspect of open innovation categorization. Based on a longitudinal literature review with three time series, this study has tried to deduct patterns of innovation among business sectors, during pre-concurrent-post periods of popularization of the term ‘open innovation’, emphasizing their implications on entrepreneurship development. However, efforts have been given to emphasize on prominent taxonomies that exists among small and medium enterprises (SMEs). Thereafter, it has tried to develop a framework on taxonomies of innovation focusing the emerging knowledge economy and the prevailing global economic crisis. The paper is an exploratory literature review and assists in knowledge acquisition.

Published: January 2014

Anti-virus software has been the main defense against malicious application and will remain so in the future. However the strength of an anti-virus product will depend on having an updated virus signature and the heuristic engine to detect future and unknown virus. The time gap between an exploit appearing on the internet and the user receiving an update for their anti-virus signature database on their machine is very crucial. Having a diverse multi-Engine anti-virus scanner in the infrastructure with the capability for custom signature definition as part of a defence in-depth strategy will help to close that gap. This paper presents a technique of deploying more than one anti-virus solution at different layers and using custom anti-virus signature which is deployed in a custom proxy solution as part of a defence in-depth strategy.
An Intelligence-Based Model for Condition Monitoring Using Artificial Neural Networks
Authors: Jenab K. , Rashidi K. , Moslehpour S.
Published: January 2014

This paper reports a newly developed Condition-Based Maintenance (CBM) model based on Artificial Neural Networks (ANNs) which takes into account a feature (e.g., vibration signals) from a machine to classify the condition into normal or abnormal. The model can reduce equipment downtime, production loss, and maintenance cost based on a change in equipment condition (e.g., changes in vibration, power usage, operating performance, temperatures, noise levels, chemical composition, debris content, and volume of material). The model can effectively determine the maintenance/service time that leads to a low maintenance cost in comparison to other types of maintenance strategy. Neural Networks tool (NNTool) in Matlab is used to apply the model and an illustrative example is discussed.
Online Communities and Open Innovation
Authors: Francesconi Alberto , Bonazzi Riccardo , Dossena Claudia
Published: January 2014

Online communities are becoming an important way to support firms towards an open innovation approach. However, knowledge shared in an online community represents only a potential for firm’s innovation aims. The effectiveness of exploration and exploitation of this knowledge depends on firm’s absorptive capacity. In this work the authors focus on the time an idea, shared within an online community, takes to be transformed from a ‘potential’ into a ‘realized’ innovation by a firm. In particular, conceiving knowledge as a trajectory across pole of attraction rather than a linear process, the authors develop a model inspired by the solar system metaphor. Preliminary results from a case study are presented. They suggest firms may improve the effectiveness of absorptive capacity exploiting the mediation role of a software tool.
Impact of Information Sharing in Alternative Supply Chain Network Structures
Authors: Dev Navin K. , Caprihan Rahul , Swami Sanjeev
Published: January 2014

Given the inherent uncertainties pervading the operational environment within real-world supply chains, it becomes imperative for each partnering echelon to focus on individual information requirements from the viewpoint of global optimization of overall supply chain (SC) performance. With this in perspective, it is expedient to explicitly model the SC network to synchronize activities across the cooperating partners. This research is concerned with the performance behaviour of two different SC network structures given different design and control parameters adopted by the partnering echelons within the assumed SC configurations. Accordingly, the authors developed discrete event simulation models of two hypothetical supply chain structures and exploit the Taguchi experimental design procedure as a vehicle for conducting the simulation experiments and analyzing its outcome. The results highlight the relative effects of the assumed design and controlling factors on system-wide SC performance and identify appropriate combinations of these factors for optimal performance concerned. For the average inventory level performance measure, key results reveal that sharing of demand information between partnering echelons should not automatically be taken for granted as a direction for performance enhancement.
Question Development in Two Online Graduate Teacher Education Courses
Authors: Wiest Lynda R. , Oikonomidoy Eleni
Published: January 2014

The authors conducted a self-study of the questions they developed for student discussion in their respective fully online graduate teacher education courses. Through individual and joint analyses of their decision-making processes and the resulting question content, the authors found that they had used both similar and different approaches to question development, influenced in part by their differing course content. Their deliberate decisions in developing questions for student discussion at times served, but in some cases constrained, course goals to have students address equity/diversity content candidly and in sufficient complexity. The authors found participating in a self-study with a colleague who had similar sociocultural perspectives useful for helping them undertake more exacting self-analyses that could lead to greater change in future development of course material.
The Impact of Australia’s Government Policy on Broadband Internet Access
Authors: Fan Qiuyan
Published: January 2014

The Australian government has recognised the importance of broadband for their social and economic development. This paper provides an in-depth analysis of the impact of policy issues on broadband Internet access in Australia. This research has clearly indicated that the state of broadband Internet access is closely related to the Government’s policy and regulatory framework. The Government based its actions on market forces as a principal driver for broadband Internet connectivity. The research has indicated that the previous regulatory competition regime, by and large, has failed to address concerns of market dominance and market power in the Telecommunications sector as is evidenced by a relatively lower speed and value of broadband services in Australia. To rectify the situation, the Australian government has recently adopted a unique National Broadband Network (NBN) plan, which is linked to the national digital economy strategy. Australia is the first country in the world where a national broadband network infrastructure company, NBN Co, is regarded as a regulated national infrastructure provider rather than as a telecommunication company. The NBN Co builds and operates an open access, wholesale only and non-discrimination high-speed broadband network, the National Broadband Network (NBN). The Australian Government's goal for the NBN is to reform the telecommunications sector and ensure every home and business across the country has access to the NBN by 2020. This paper examines the policies underlying the NBN and discusses current practices and potential benefits of the NBN.
Application of Behavioral Theory in Predicting Consumers Adoption Behavior
Authors: Shareef Mahmud Akhter , Kumar Vinod , Kumar Uma , Hasin Ahsan Akhter
Published: January 2014

A society produces some values, ideas, intentions, and speculations about the human personality. These perceived psychological phenomena depend on rules, regulations, relationships, culture, tradition, etc. Depending on cultural factors, the behavioral intention to adopt online system operated through information and communication technology (ICT) can be affected vividly. Since adoption of ICT potentially depends on citizens’ beliefs and attitude toward technology, adoption behavior of users should be revealed considering citizens behavioral differences. Technology Acceptance Model (TAM) by Davis et al. (1989) is a strong information system theory that models how users come to accept and use a technology. However, the foundation of TAM including many other ICT adoption models has been developed from the deep insight of two popular and widely used behavioral theories named Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB). To understand ICT adoption behavior, these two theories can provide generalized concept of human behavioral attitude and different beliefs which ultimately lead to behavioral intention to adopt ICT. This study has set its first objective to explore TRA and TPB as the theoretical foundation of behavioral attitude toward ICT-based online adoption. Then, based on that theoretical paradigm, our second objective focuses on developing a theoretical framework of revealing generalized ICT adoption and diffusion behavior.

Authors: Kim Young Moon , You Ki Pyo , You Jang Youl
Published: January 2014

Most of modern tall buildings using lighter construction materials are more flexible so could be excessive wind-induced vibrations resulting in occupant discomfort and structural unsafety. The optimal control technique for reducing along-wind vibration of a tall building based on the linear quadratic regulator (LQR) is presented in this work. Actively controlled reduced along-wind vibration response is obtained from the tall building installed in an active mass damper (AMD) with a LQR controller. Fluctuating along-wind load is generated using numerical simulation method, which can formulate a stationary Gaussian white noise process. Simulating wind load in the time domain using known spectra data of fluctuating along-wind load is particularly useful for estimation of windinduced vibration which is more or less narrow banded process such as a along-wind response of a tall building. In this work, fluctuating along-wind load acting on a tall building treated as a stationary Gaussian white noise process is simulated numerically using the along-wind load spectra proposed by G. Solari in1992. And using this simulated along-wind load estimated the reduced along-wind vibration response of a tall building installed in an AMD with a LQR controller.

Published: January 2014

Motor of electric vehicle is able to be used to brake regeneratively, so braking energy can be recycled. Braking stability of electric vehicles with electro-hydraulic hybrid braking system can be influenced by braking force distribution between hydraulic braking force and regenerative braking force. In order to research on braking stability and braking energy recovery, simulation platform of electro-hydraulic hybrid brake system based on Carsim and Matlab/Simulink is built, and a control strategy of electro-hydraulic hybrid brake were proposed. The vehicle simulation models with electro-hydraulic hybrid brake system and with conventional hydraulic braking system were applied the brake on different adhesion coefficient separately. The simulation results show when electric vehicle is in the conditions of low braking intensity, all vehicle braking force is provided by regenerative braking force, and braking energy can be not only recycled, but brake performance requirement can also be satisfied; when electric vehicle is in the conditions of moderate braking intensity, regenerative braking and hydraulic braking are coordinated with each other, electro-hydraulic hybrid brake can not only satisfy the same and better brake performance, but also braking energy can be recycled and demand of hydraulic pressure can be reduced.

Published: January 2014

An autonomous mobile robot in a human living space should be able to not only realize collision-free motion but also give way to humans depending on the situation. Although various reactive obstacle avoidance methods have been proposed, it is difficult to achieve such motion. On the other hand, 3D X-Y-T space path planning, which takes into account the motion of both the robot and the human in a look-ahead time horizon, is effective. This paper proposes a real-time obstacle avoidance method for an autonomous mobile robot that considers the robots dynamic constraints, the personal space, and human directional area based on grid-based 3D X-Y-T space path planning. The proposed method generates collision-free motion in which the robot can yield to humans. To verify the effectiveness of the proposed method, various experiments in which the humans position and velocity were estimated using laser range finders were carried out.

Authors: Zhou Zhou , Chen Zhao Xi , Meng Xiao Hong
Published: January 2014

Regional gravity anomaly provides important information for the study of regional geologic structure and the division of tectonic units. The major concern of the geophysicists is how to obtain the detailed data of regional gravity using reliable methods. In this study, curvelet transform was used for the first time in the multi-scale analysis of data of regional gravity. As one method for multi-scale geometric analysis, curvelet transform overcomes the limitations of wavelet transform in representing the high-dimensional singularities such as edges and contours. When processing of the data of regional gravity, the curvelet transform can more effectively present the detailed information. In this study, the data of synthetic model was respectively used for the experiments based on the wrapping algorithm of second-generation curvelet transform in combination with translation of cycle, iterative operation and Monte Carlo strategy for threshold adjustment. The experimental results show that the curvelet transform is efficient in multiscale separation for the data of regional gravity. This technique provides reference to the application of relevant multiscale and multi-orientational transform methods in the processing of data of gravity.

Authors: Wang Kun , Chen Jing Ya , Qu Xiang
Published: January 2014

Sasobit warm mix drainage asphalt pavement has become increasingly popular due to its environmental benefits and comfortable using effect. However, test results show that its low-temperature and anti-fatigue performance have a certain degree of reduced. To improve the performance of asphalt four different doses (1%, 3%, 5% and 7%) of salt are added to the Sasobit asphalt. Laboratory tests were used to simulate short and long term aging asphalt in the process of construction and using pavement. A series of binder tests including bending beam rheometer (BBR), dynamic shear rheometer (DSR) and Brookfield viscosity tests were conducted. Results show an increase of rutting performance for warm mix binders with Sasobit while asphalt with salt has similar high temperature performance to original asphalt. Unlike Sasobit which has a decrease of cracking performance for asphalt at low-temperature, salinity can greatly improve the Low-temperature performance. And the low-temperature cracking performance and anti-fatigue performance presents a tendency of climbing up first and then declining with the increase of salinity. The figure of viscosity-temperature curve shows that the optimum of salinity is 5%.Further more, asphalt with Sasobit and salt can gain better performance and same mixing and compaction effect in lower 20°C than hot mix asphalt without it.

Gait Measurement System for the Elderly Using Laser Range Sensor
Authors: Yorozu Ayanori , Takahashi Masaki
Published: January 2014

Gait measurement is important in various applications such as monitoring systems for the elderly. This paper presents a gait measurement system applicable to the elderly using a laser range sensor (LRS). An LRS can obtain high accuracy distance data over a wide range and leg position can be calculated based on characteristic leg patterns from the scan data. However, situations in which a leg is hidden from the LRS or both legs are too close together lead to false tracking or losing track of both legs entirely. In the case of the elderly in particular, these situations are likely to occur due to slow movement or narrow stride. To solve these problems, we present a novel leg detection method with five observed leg patterns and global nearest neighbor (GNN)-based data association, using a variable gate based on the state of each leg. Experimental results of several elderly people show that the proposed system can reduce the chances of both false tracking and losing track of both legs, and can acquire the accurate trajectory of both legs.

Firstly, the training set of the back propagation (BP) neural network is formed by the image feature point extracted from the binocular vision system. Then the cooperate particle swarm optimization (CPSO) algorithm is introduced to optimize the weights of the BP neural network, making the network with a stronger ability of the global optimization. Experimental results demonstrate that the proposed CPSO-BP-based algorithm has a higher calibration precision than the traditional BP-based calibration method.

Published: January 2014

The paper presents basic geoelectric models given the seismoelectric effect for application in pro-cessing algorithms of the geodynamic information. They can improve the reliability of the estimation under the control of geodynamic processes and phenomena taking place in the surface layers of the geological environment. The models under the effect of longitudinal and transverse modes of seis-mic waves on a small particle of the environment are considered. A one-dimensional model of the environment under the joint effect of the longitudinal and transverse modes of seismic waves is pre-sented. The mathematical modeling of two media under the effect of longitudinal elastic defor-mation is given. The dependences of the relative change in the transfer coefficient for two media on the electrical parameters of contrast media both resistivity and dielectric constants are discussed. Based on the results of mathematical modeling, the application of seismoelectric effect in geody-namic control systems proves to be highly efficient.

This paper describes the driving control system for a powered wheelchair using voluntary eye blinks. Recently, new human-computer interfaces (HCIs) that take the place of a joystick have been developed for people with disabilities of the upper body. In this paper, voluntary eye blinks are used as an HCI. However, the problem with this HCI is that the number of input directions and operations is smaller than that of a joystick, which causes inefficient movement. Therefore, assistive systems are needed for efficient and safe wheelchair movement. The proposed system is based on environment recognition and fuzzy logic. It can detect obstacles and passages, and speed and direction are calculated automatically for obstacle avoidance and right/left turns. The systems effectiveness is demonstrated through experiments with a real HCI in a real environment.

The microscopic analysis of 93W-4.9Ni-2.1Fe (wt. %) tungsten heavy alloy by hot-hydrostatic extrusion with severe plastic deformation strengthening were experimentally investigated mainly by transmission electron microscopy. Due to the profound differences in hardness of the tungsten particles and the NiFeW matrix a special TEM specimen preparation method had to be employed.It was shown that the microstructure of the as-extruded alloy was characterized by elongated tungsten particles with refinement cellular sub-structures consisting of high-density dislocations embedded in a binding Ni-Fe-W matrix phase with fine dynamically re-crystallized grains.

The purpose of this work is to investigate the effects of flame retardants on long-term aging and rheological characteristics of the modified asphalt binder. The flame retardants included #A (decabromodiphenyl ether, antimony trioxide, and zinc borate with the ratio of 3:1:1 by mass) and #B (tetrabromobisphenol A bis (2, 3-dibromopropyl ether), antimony trioxide with the ratio of 2:1 by mass). The results indicated that flame resistance of asphalt binder increase after PAV and UV aging processing, and the complex modulus also increase. The UV aging brings a plateau region of the phase angle master curves over the intermediate temperature range. This behavior is very weak in the studied PAV aging and unaged asphalt binder. Compared with #B modified asphalt binder, #A modified asphalt binder showed better flame retardancy and rheological characteristics before and after aging.

Sodium borohydride hydrolysis is one of the promising methods for the supply of hydrogen on-board in fuel cell vehicle. A suitable catalyst is required to control the hydrogen release from stable alkaline sodium borohydride solution. The present paper reports the effect of Co (II) doped zeolite-X and K-chabazite catalysts in sodium borohydride hydrolysis reaction. Kinetics of the hydrolysis reaction was observed to get enhanced by the use of these catalysts. Activation energies for Co (II) doped K-chabazite and zeolite-X are found to be 30.7 and 48 kJ mol-1, respectively.
Wetting Behavior of Al Melt/C Interface and Al-Ti Melt/C Interface Assisted by AlF3-KF Salt Eutectic

Published: January 2014

This doc This paper is concerned with the wetting of Al melt/graphite (C) substrate and Al-Ti melt/graphite (C) under the action of AlF3-KF salt eutectic. The results show that the intrinsic non-wetting behavior in the Al/C system was confirmed. The reason is because the existence of oxide film of Al melt obstructs the wetting between C and Al melt. However, due to assisted wetting of AlF3-KF salt eutectic, the good wetting behavior of Al,Al-Ti/C system is attributed to the strong physics wetting and subsequent interaction wetting. During the interaction wetting, Al4C3compound forms at the Al/C interfaces while Al4C3and TiC compounds form at the Al-Ti/C interfaces. In the meantime, high temperature effect formed at the interfaces owing to the reaction between Al-Ti and C attains the thermodynamics transformation condition of Al4C3into TiC.

Published: January 2014

Micromachining techniques has increased the demand for precise and accurate instruments which are used in many industries. Glass materials offer higher challenges in micro machining as they are tough, non-conducting and difficult to machine with conventional machining operations. Electro Chemical Discharge Machining (ECDM) is a new non-conventional hybrid machining process which combines the features of Electrical Discharge Machining (EDM) and Electro Chemical Machining (ECM) to machine both conducting and nonconducting materials. In the present paper effect of various process parameters like voltage, concentration of electrolyte, duty factor and temperature on ECDM process are studied to obtain desired micro channels in soda lime glass. Design of Experiment (DOE) is used to plan and conduct the experiments. The Response Surface Modelling (RSM) is used for characterising non linear output responses in terms of material removal rate and surface finish. Modeled results are validated with experimental values.
