Title: Texture analysis based feature extraction using Gabor filter and SVD for reliable fault diagnosis of an induction motor
Abstract:
This paper presents a texture analysis based feature extraction method using a Gabor filter and singular value decomposition (SVD) for reliable fault diagnosis of an induction motor. This method first converts one-dimensional (1D) vibration signal to a two-dimensional (2D) grey-level texture image for each fault signal. Then, the 2D Gabor filter with optimal frequency and orientation values is used to extract a filtered image with distinctive texture information, and SVD is utilised to decompose the Gabor filtered image and select finer singular values of SVD as discriminative features for multi-fault diagnosis. Finally, one-against-all multiclass support vector machines (OAA-MCSVMs) are used as classifiers. In this study, multiple induction motor faults with different noisy conditions are used to validate the proposed fault diagnosis methodology. The experimental results indicate that the proposed method achieves an average classification accuracy of 99.86% and outperforms conventional fault diagnosis algorithms in the fault classification accuracy.

Title: Shadow detection using chromaticity and entropy in colour image
Abstract:
Shadows in an image often bring a significant problem which can cause unintended negative outcome, so how to detect shadow is an important issue of computer vision tasks. This paper proposed a method to detect shadows from real images. Due to shadows in image have a dark pixel value, shadow candidates are defined. Shadow candidates have been estimated and detected by chromaticity of colour image and threshold image using entropy. Some experiments are conducted so as to verify the proposed method, and results show that the proposed method can detect shadows in colour image.

Title: The investigation of relationships: self-esteem, self-confidence, and conduct problems in counselling
Abstract:
The purpose of this study was to investigate the relationship between self-esteem self-confidence, and conduct problems. It demonstrated that the correlation of self-esteem and self-confidence was not significantly related to the children and adolescents' conduct problems. Also, there is no direct relationship between self-confidence and parents' couple intimacy. However, self-esteem and parents' couple intimacy were significantly related, indicating that self-esteem and self-confidence are different. As demonstrated by the hypotheses, the relationship of self-esteem and self-confidence is significant. In particular, self-esteem is more significant than self-confidence in this study. The relationship of self-esteem and parents' couple intimacy, and self-esteem and self-confidence, were accepted. It indicated that self-esteem and self-confidence are very similar but they have different ripple effects. This study aims to examine coping conduct problems, self-confidence, and self-esteem of students in Korea. Results of the study also gave information about the general information relating to the self-esteem of 1st to 12th grade students. The results produced evidence for the obvious correlations between coping behaviours, and self-esteem as well. This data will help counsellors and educators recognise their students' difficulties when they practice in counselling settings and identify how to help students use their counselling more proficiently.

Title: User interface using bounce for realistic movement on smart TV
Abstract:
In this research, we designed the various movements on the screen based on a touch pad of a smart TV. Due to the increment of smart TV, diverse interfaces are applied on the screen and movement is the crucial part of the interfaces. However, the screen is comprised of pattern as a button; the availability of new interface is less effected for users. Therefore, it is necessary to research new screen composition to escape the existing one. Smart TV's screen layout suggests new directional properties such as moving the position where we want with simple gesture. Moreover, we found the fact in this research that less change from movement of many objects is showed compared with existing movement. Based on the result of this research, it is possible to show the motion of various effects and two-dimensional movement better than existing one-dimensional movement.

Title: Analysis of serious games for preventing internet gaming addiction
Abstract:
Internet addiction and internet gaming (game) addiction are two terms regularly used in our daily lives, however, their distinction is rather vague. Internet gaming addition refers to a psychological, emotional, and social state where one, due to increased tolerance and dependence to games and other reasons, loses control over and plays internet games excessively and compulsively, and any efforts to reduce or stop playing will be ensued by withdrawal symptoms. One means to better the problems caused by gaming addiction is development of a variety of serious games and related services. Whereas internet games are played for entertainment, serious games utilise the entertainment function to further education and addition preventive measures objectives.

Title: A tree cognitive navigation system based on two-dimensional code and GPS
Abstract:
The recognition of trees plays an important role in the construction of ecological civilisation. In order to strengthen tree information management and help the public to have a better understanding of trees, an Android-based tree cognitive navigation system for smart phones was developed. Using two-dimensional code and GPS technologies, the system can rapidly acquire geographic coordinates and species of trees. In this paper, the theory, system framework and key technologies of the system are presented. Subsequently, a tree cognitive system based on two-dimensional code and GPS was developed for Beijing Forestry University. The system implementation approach has broad application prospects. The case study showed that it is portable, practical, user-friendly, and network-independent and has good potential for application and expansion.

Title: Estimating the sentiment strength of a word using word similarity
Abstract:
Identifying the sentiment orientation and strength of a sentence or phrase is one of the crucial issues in opinion mining. A dictionary approach to this problem is to use the sentiment orientations and strengths for the words included in a given document unit. This paper proposes a novel method for estimating the sentiment strength of a word using similarities between a target sentiment word and sentiment words in dictionary. To calculate the word similarity, we introduce the notions of relative similarity and adjusted similarity. The experimental results from the analysis of Facebook text data demonstrate the effectiveness of the proposed method in terms of the root-mean-square-error.

Title: Game operation query language for facilitating game server's FCAPS operation
Abstract:
Game companies require successful game operation for their revenue maximisation. In an operation phase, they need not only operators who are experts in non-functional and operational issues but also developers who are experts in game development. Game server should manage several operational issues such as fault recovery, performance metering, and configuration management during game service period. However, most game server operators do not have programming expertise. To support successful fault, accounting, configuration, performance, security (FACPS) operation without programming expertise or development knowledge, we introduce domain specific language (DSL) operation approach for usual game operators. We design GOQLDSL, focusing on fault, configuration, and performance management issues. We experimented with 15 game server operators who are working in major game publishers. Experimental results show that GOQL was attractive to game operators because it is functional and does not require programming knowledge even in the situation that needs programming source modifications. For the future research, we will extend our textual version of GOQL to visual language version to give more convenience and intuitive advantage to game operators and novice developers. To cover this, we require study on visual notations, UX-related elements, and visual transformation of text.

Title: Automatic classification of Lithuanian parliament bills
Abstract:
Quantitative methods are becoming more and more important in political science. However, they are not applicable without computers and computer based systems. In this paper we apply natural language technologies, mainly text classification, to categorise bills of the Lithuanian parliament into the predefined groups for further use in voting analysis and in other text analytic tasks. As only the titles of bills were used, in general it can be claimed that the problem of short text classification, which is poorly explored in consideration with the Lithuanian language, is addressed in this study.

Title: Modelling technique of the object-attribute system oriented to data mining
Abstract:
The research of modelling the object-attribute system, essentially a two dimensional problem, belongs to the domain of interpretative structural modelling and it is one of the basic problems in the data mining field. Firstly, this paper proposes and demonstrates the subsystem judgement theorem. In order to solve the problem above, this paper puts forward an algorithm which can reduce the scale and the dimension of the original data through modelling the object-attribute system based on the object similar feature matrix (OSFM). In the last part of the paper, a numerical value example is provided to show the whole process of the method.

Title: Relationships among customer loyalty, customer satisfaction, corporate image and behavioural intention on social media for a corporation
Abstract:
In this paper, how customer loyalty, customer satisfaction, corporate image and behavioural intention affect each other on social media and how to make the benefit maximisation for corporation are explored. We leverage natural language processing (NLP) techniques analysis emotion of comment and retweet in the text, and combined with the other attributes and behaviour of the Weibo users who interact with the corporate account to research the relationships on social media. The results show that customer image has a direct impact on customer satisfaction and has an indirect impact on customer loyalty. Customer loyalty is impacted by customer satisfaction and behaviour intention. The influence of customer image on behaviour intention and loyalty and the influence of customer satisfaction on behaviour intention are not very significant. As the results suggest, Shanghai Peace Hotel needs to more widely publicise their corporation, such as with celebrity endorsement (Lv et al., 2013).

Title: Research on book shopping website interface based on the eye tracker
Abstract:
This study aims to analyse the behaviour of consumers when they buy books online, and analyse the law of their scanning of the products and their focus when they check the information. In the experiment, 20 subjects must follow the instruction to complete two specific tasks, and the eye tracker recorded their eyes' movement data automatically. According to the heat map, researchers divided the area of interest (AOI) which got the attention of subjects and analysed the data in the AOI. Combined with the interview and analysis, they found that: a) The customers tend to view pages following an 'F' pattern: attention is largely focused on the upper and left part; b) the upper part of webpage is more attractive than the lower part; c) in terms of text, Dangdang.com is more attractive than Amazon because Amazon has a cluttered text typography; d) consumers like to check the goods' information and the comments of the goods when they choose them; e) Dangdang.com's operation is simpler than Amazon when they are completing the order.

Title: Challenges of software developers: the Namibian Government experience
Abstract:
Almost 15 years after the National Development Program (NDP) was initiated, the Namibian Government continue to outsource most of its software development to companies from other countries. This is considered by the general populace of the country to have a negative impact on the economy, as well as skill and knowledge transfer. This research, through multiple case studies, examined and discusses the impact of lack of in-house software development experts in the country. From the empirical study, a framework for software development skill (FSDS) was developed. The framework consists of factors which include strategic objectives of the government, strategic objectives of the IT divisions, policy and standards, IT management support and skills and development. The primary aim of the FSDS is to assist the Namibian Government institutions to understand the influencing factors, in building software development capacity in the country.

Title: Research on key techniques of cryptographic access control and properties optimisation in cloud storage
Abstract:
With the analysis of data privacy protection requirement from the users, we proposed cryptographic access control scheme and key distribution scheme based on ciphertext-policy attribute-based encryption (CP-ABE), and gave a hierarchy based on CP-ABE key generation algorithm. This scheme uses precise identity and hierarchal structure as the user attributes, and supports hierarchal key generation. As the cloud data are encrypted by the users, the data privacy protection can be effectively achieved in cloud storage against network attackers even if cloud service provider (CSP), suitable for the multi-user who has hierarchal structure attributes sharing cloud storage services environment. We also proposed two schemes for improving the usability of cloud storage system. The first one is that the metadata information of unstructured data are stored in cloud using non-relational database MongoDB, which can greatly improve the speed of data access. The second is data migration algorithm based on physical volume, which can migrate data to the matching devices automatically depending on user access frequency value. Experimental results showed that these programs were able to improve the storage efficiency of cloud storage system. The study is of theoretical significance and practical value to the similar systems.

Title: Informal interactive bring your own device strategising practices of South African small and medium enterprises
Abstract:
The purpose of this study is two-fold: firstly, to identify factors affecting BYOD adoption in South African SMEs and secondly understand strategies SMEs engage in with regard to BYOD. Following an interpretive approach, and interviews as a means of data collection; the findings show that SMEs are consciously aware of BYOD but are not eager to formalise their strategy. Instead, SMEs engage in informal interactive strategising despite their concerns of cost, security and privacy. SMEs did not view BYOD as a cost saving approach but rather as a double end sword that brought privacy and security concerns; unintended consequence; and no improvement in productivity. Further findings show how SMEs, specifically employees advocated the need for a policy prescribing how mobile devices should be used and in so doing perpetuating the interactive strategising. External factors such as changing laws and regulation were perceived as barriers towards a formalised BYOD strategy.

Title: Collaboration environments for small and medium-sized architecture, engineering and construction enterprises: success factors in implementation
Abstract:
Collaboration in the architecture, engineering and construction (AEC) sector increases productivity, improves quality, competitiveness and profitability. This poses the problem of what are the most appropriate collaboration methods available. With building information modelling (BIM) being imposed by the UK Government on AEC projects, the development of new technology is one solution, but ensuring the whole-sector adoption is fundamental. It is commonly observed that SMEs have fewer chances to get it right and so they need guidance. A qualitative study of 14 cases was developed to map the current practice of implementations and their success level. The case studies revealed a number of factors affecting the success at the organisation level. This also led to further quantitative investigation of the factors affecting the collaboration at the end-user level. The results suggested that the success of collaborative technologies depends on 23 factors. Recommendations from these findings are used to suggest a path for SMEs to implement BIM.

Title: Hadoop ecosystem as enterprise big data platform: perspectives and practices
Abstract:
Innovation in Hadoop and other related big data technologies in recent past bring on to the table promises around better management of enterprise data at much lesser cost but with more business benefits. However, managing big data environment at enterprise level is an involved task from cost and operational perspectives. Supporting various types of enterprise use cases with different workload patterns in the same cluster, minimising the data movement, assuring different service level agreements (SLAs), ensuring data lineage, veracity, and security are some of the key challenges. In this paper, we delve into these key challenges from practitioners' perspective based on lessons learnt from various big data implementation scenarios. We also discuss the concept of Hadoop ecosystem as big data platform which can potentially address these challenges. Finally, we also provide a prescriptive approach which can help moving towards the vision of enterprise big data platform using Hadoop ecosystem.

Title: Factors affecting diffusion and adoption of information and communication technology among rural users in Khyber Pakhtunkhwa Province, Pakistan
Abstract:
The purpose of this study is to investigate and categorise the factors influencing diffusion and adoption of ICT in the rural areas of Pakistan. The research deals principally with common people of the rural areas of Khyber Pakhtunkhwa Province for adoption of ICT in their daily life. The sample size encountered was 330 respondents, who were selected through random sampling technique. Primary data was collected from people belonging to different races of life throughout the province. The results of the study were calculated by using confirmatory factor analysis (CFA) and structural equation modelling (SEM) techniques which show that the overall ICT diffusion and adoption is profoundly influenced by seven factors, including social, political, environmental, regulatory, technological, economic and legal. The study confirms a most significant impact of social and political factors upon ICT diffusion, whereas the remaining factors seem to have a moderate impact.

Title: Finding linkage between sustainability science and complex networks
Abstract:
Sustainability science has been widely accepted worldwide as an important research field worldwide. Since it is widespread in many research fields such as environmental science and engineering, architecture, materials science, and civil engineering, it is important to discover the hidden connections between sustainability science and other academic fields. For this purpose, supporting tools are necessary. This paper investigates the relationship between sustainability science and complex networks on the basis of citation network analysis using large datasets of academic papers. First, citation networks are generated on the basis of academic paper datasets and clustered to understand the research fields of sustainability science and complex networks. Next, we measure the textual similarities among the clusters in these fields and analyse the shared terms to find the overlapping research areas that connect the two fields. These results offer overviews of how complex networks contribute to sustainability science and assist the formation of policies that promote key results in artificial intelligence toward future sustainable societies.
