Learning users' frequent patterns is very useful to develop real human-centered environments. By analyzing the occurrences of events over time in a home automation system, it's possible to find periodic patterns based on action-time relationships. However, the human behavior could be better defined if it's related to chained actions, creating action-action relationships. This work presents IntelliDomo's learning layer, a data mining approach based on ontologies and production rules that aims to achieve those objectives. This module is able to acquire users' habits and automatically generate production rules for behavior patterns to anticipate the user's periodic actions. The learning layer includes new features looking for the adaptability and personification of the environment.

The software protection is the key technology for the shareware and it can delay and prevent the software reverse and cracking. There are many methods such as junk code, anti-debug, virtual machine, deformation, packers, encryption and verification. The software registration is the most important step of protection and it can be implemented by many forms such as network registration, license key or file, dongle. This paper introduces and compares these protection methods. Some architectures of protection based on encryption and verification are provided and they are realized by RSA encryption and many verification methods which include self verification and key data verification. The method use the exe file and DLL file to protect each other and use the license file to check and provide software function. The method uses the RSA in the license key file to register and it can make it difficult to create the key generator for the cracker.

Both parallel and distributed network environment systems play a vital role in the improvement of high performance computing. The primary concern when analyzing these systems is multiprocessor task scheduling. This paper addresses the problem of efficient multiprocessor task scheduling. A multiprocessor task scheduling problem is represented as directed acyclic task graph (DAG), for execution on multiprocessors with communication costs. In this paper we have investigated the effectiveness of a proposed paradigm based on genetic algorithms (GAs). GAs is a class of robust stochastic search algorithms for various combinatorial optimization problems. We have designed a GA based encoding mechanism that uses multi-chromosome encoding scheme. The implementation of the technique is simple. The performance of the designed algorithm has been tested on a variety of multiprocessor systems both heterogeneous as well as homogeneous.

Mineral processing plays a key role for preparing fuel or materials in coal industry, steel industry, and non-ferrous metals industry. Lack of energy resource and pollution has baffled the economy development of China. Research on mineral processing is giving more and more attention and Mineral processing engineering education has been given high priority in China. Taking the personnel training of coal processing and utilization as a background, the development of mineral processing engineering education in China University of Mining and Technology (CUMT) is introduced in this paper. The faculty group, laboratory and scientific research conditions of the discipline are presented. The personnel training scheme of the subject, the courses system, student criterion are also discussed, and how to cultivate excellent graduates in mineral processing engineering field to meet the demand of high education internationalization are discussed.

All awnings applied in civil buildings usually have two functions: one is to resist rain and the other is to shelter from sunshine. However, the new-type awnings have the third function. The extra function is PV power generation. As the shade surface of awnings. the type of solar battery board decides whether the new-type PV powered awnings possess the above-mentioned three functions, as well as is one of the keys to whether they are worth popularizing. This text focuses on the exploration and study on the selection of solar battery board when they are used as the materials of shade surface on awnings. Based on their three basic functions, via analyses and comparisons in translucency and PV transmission rate etc. It is put forward that using thin-film solar battery board as the adumbral material is the best choice.

Depending on CCD camera to detect driver fatigue has been proposed in past research. This paper proposes a rapid method of driver fatigue detection by applying AdaBoost algorithm,and PERCLOS to judge the degree of the driver fatigue. Compared to the original method, this method reduces redundant facial texture information, and accelerates the speed of eye state detection while improving detection accuracy rate of driver fatigue. The experiments results show that this method is fast. effective and easy which can be used in real-time detection of driver fatigue.

The migrating workflow is a new direction within the workflow management area. The access control model in a migrating workflow system is one of the most important areas in the research. In the traditional access control model the instance needs to apply permission in each site. In this article, we present the conception of sites' service alliances (SA) into the migrating workflow system to reduce the cost of access control. In the system, there are several s. The sites which belong to the same provide same service and resource to the instance. With conception of sites' service alliances we adapt the migrating workflow system model and present a new access control model on it. In the new access control model, the instance applies permission for a sites' service alliance. So the instance does not need to apply permission in each site. The cost of access control is reduced largely.

The purpose of this paper is to solve the problem of matching two 3D point sets quickly in the field of robot vision. Moravec vertical interest operator is used to extract vertical edge feature of objects. The method of the sum squared difference (SSD) is used to match the feature points and obtain the 3D point sets which contain vertical line feature. Find the transformation relation of rotation and translation of corresponding straight lines in two 3D point sets according to the projection point of vertical line projected into x-y plane. Depending on the transformation relation, it can match two 3D point sets. The experiment results illustrate that this method has good exactness and robustness.
