This research is concentrated on using unsupervised learning technique and digital image processing to cluster mineral materials, Electrofused Magnesia Oxide specifically, for industry automation. We proposed a technique to construct an image database by generating data from images using a digital image process. This is based on a simple histogram mode and intensity deviation. A group of two popular...
This study developed cost functions, which were expressed as functions of pipe sizes and excavation depths, applicable to open cut and jacking techniques for construction of sewer systems. Data for several real sewer system construction projects in Taiwan were investigated to verify the accuracy of the cost functions. The cost functions developed in this study are more realistic, practical, accurate...
This study investigates how doctoral students experience supervision during their studies in one Department of Industrial Engineering and Management, and how different student groups differ from each other in their supervision experiences. The focus of comparison is on part-time vs. full-time students, newcomers vs. old-timers in study stage, and beginners, proceeders and achievers in research progress...
This paper studies the cost-reducing and quality-improving innovation incentives of a downstream durable-good monopoly. The monopolist's purpose is to maximize its profits under the assumption of an imperfect competitive upstream market. Then optimal licensing schemes for an outside quality-improving innovator are proposed. It is found that the monopolist only has quality-improving while but cost-reducing...
How to determine project investment reasonable and to improve the utilization of funds is an important content of owners' investment management. However, as a function-cost analysis method, value engineering provides an effective way to solve these problems. This paper analyzes the investment control method of construction project with Value engineering at design stage, focused on the application...
Metaphor as part of the cognitive linguistic theory has penetrated into different fields and different styles of discourses. It can be found in almost all kinds of styles of writing discoursed. By studying the developing stages of metaphor, especially by analyzing different kinds of usage of the conceptual metaphor in cognitive linguistics, this paper finds that conceptual metaphor in cognitive linguistics...
The evaluation of burst-proneness risks has affected the coal and rock mining progress and development. The quality evaluation system framework of burst-proneness risks indexes is established. Fuzzy evaluation index system is proposed to take into account various factors. As to index system, comprehensive fuzzy evaluation model and methods are setup and used to check for practical example. Using comprehensive...
Technology mediated support is very crucial for the lifelong education students in the National Open University of Nigeria. This paper is therefore focused on giving account of the concept of lifelong education in this university and how technology is being used to transmit knowledge, reduce distance between learners and the facilitators, support the learners academically and psychologically and ensure...
How to rapidly capture the wanted video data at the sea video database is the currently hot research topic. This paper put forward to an algorithm based on artificial intelligence for video retrieval; the results of experiment had been given and compared with key frame-based video retrieval (KFVR). The retrieval precision of our algorithm is higher than KFVR about 4%.
This paper explores the effect of model change from direct to distribution on the behavior of buyer and supplier and their relationship. First, a theoretical framework is established to investigate the effect of model change based on literature review. Then, a case study is presented to illustrate the developing relationship between a world-class American company and its Chinese suppliers. Finally,...
This paper analyzes characteristics of network education, introduces the importance of education with network resources and the autonomous learning ability required in network education. It further proposes the main problems of students in network educational environment and provides relevant solutions and strategies.
Environmental disruption from mining activity has increased markedly in the 21st century leading to increased emphasis on reconstructing natural environmental processes in post-mining landscapes. We present simulation and assessment approach to designing post-mining landforms at Ranger uranium mine in Northern Australia. A mine landform design was developed from mine planning estimates of waste rock...
Parametric studies have been carried out for the quartic-polynomial regression problem demonstrated in the Genetic Programming (GP) v3 toolbox of Matlab. Many classification schemes and modeling issues are polynomial based. Every possible combination originating from all available options between the two genetic parameters namely ?elitism? and ?sampling? has been analyzed while keeping all other parameters...
As important social clues, gaze direction and expression usually influence people's social interaction in their communication, and facial cognition is also a hot topic in social cognitive study. In our studies, by comparing facial cognition in upright and inverted face, considering both gaze direction and expression, we tried to explore the mechanism of gaze and expression processing by the method...
According to the problems in the traditional experiment teaching mode, some opinions about the reform of experiment teaching in analogue circuits are presented in this paper. New teaching mode and teaching method adjust analog circuits experiment teaching process. In addition, combined with the status and development direction of the current analog circuit experiment course, this paper explore and...
Rapidly growing quantities of digital video have made video data become a more important role in many applications than ever. Virtual scene construction also uses video materials as a rich resource. In order to manage the video materials like salient objects and scenes, an effective video retrieval system is required. In this paper, we present a video database management system using a hierarchical...
In our earlier perception study, we observed that familiarity with first language (L1) phonemic length contrasts in Japanese does not transfer optimally into an unknown language, Arabic. We hypothesized that this finding is related to cross-language differences in how vowel length contrasts are phonetically realized. The present study compares vowel length contrasts that are phonemic in three typologically...
We show how to compute a minimal Riccati-balanced state map and a minimal Riccati-balanced state space representation starting from an image representation of a strictly dissipative system. The result is based on an iterative procedure to solve a generalization of the Nevanlinna interpolation problem.
Robust hash algorithms can be used as tools for identifying or discriminating content, e.g. for automated tracking systems and filters for file sharing networks. When they are used in security relevant applications, such as in content-fragile watermarks or for recognizing illegal content, the security of the hash value generation becomes an important issue. In this paper we discuss possible attacks...
The study on the bearing capacity and settlement is important to a project. It is useful and concrete to develop a model with some intelligent methods in artificial intelligence area for the prediction of some big structure projects. The validity of the models has been proved by some civil engineering practices. Therefore, the research of bearing capacity and settlement characteristics of rigid pile...
