The science laboratory class is a key class in some universities. They learn a wide range of knowledge rather than specialized ones. To deepen knowledge in limited time, we propose a new method for database course. Students learn the basic knowledge from textbook. For difficult point, they can return to videos on MOOC websites. If there are still problems, they may discuss with teacher and classmates...
The precondition of productive data mining is having an efficient database to work on. The BioVid Emo DB is a multimodal database recorded for the purpose of analyzing human affective states and data mining related to emotion. Psychophysiological signals such as Skin Conductance Level, Electrocardiogram, Trapezius Electromyogram and also 4 video signals were recorded. 5 discrete emotions (amusement,...
In order to solve the serious problem of high energy consumption in large public buildings, lots of building energy monitoring systems (BEMS) have been established all over the whole country in recent years. The application of the Internet of Things (IoT) in building field will certainly raise the function of building auto control technology, and reform the monitoring control situation of building...
Peer-to-peer file-sharing has been increasingly popular in the last decade. In most cases file-sharing communities provide only minimal functionality, such as search and download. Extra features such as recommendation are difficult to implement because users are typically unwilling to provide sufficient rating information for the items they download. For this reason, it would be desirable to utilize...
With high increasing documents and electronic texts in Persian language, the use of fast methods to achieve texts through huge sets of documents is highly crucial. Persian text summarization which shows the main concept of a text in minimum size is an effective solution. One of the steps in Persian text summarization is to stem and eliminate common words. The aim of this research is to stem words...
In the rapid development of global market, there is an urgent need for manufacturing enterprises of China to provide training to its employees to ensure their continuous competence in handling their task. E-learning systems provide a variety of instructional aids and communication methods, and offer learners great flexibility as to the time and place of instruction.

In this paper, we present the technique to manage user profiles and authentication using LDAP (lightweight directory access protocol). The user profiles maintained in the LDAP directory information tree (DIT) which contains various information about users. This information can be retrieved by the users depending upon the level of access provided to them on the network. Various services use this authentication...
To effectively improve the efficiency of energy supply, quantification is required to determine its significance in our daily lives. Building an energy management system to monitor and acquire information such as energy supply and environmental factors is a necessary task for the quantification of energy consumption. We chose to build the energy management system with LonWorks control network because...
In this paper, a secure face recognition system is presented, in which face detection is performed with skin color detection followed by light normalization and normalized cross correlation. Principal component analysis (PCA) is used for face verification. Due to the rising concern about the security and privacy of the biometric system, we offer a secure storage for user records by encrypting them...
