Smart environment is widely applied and it is the most important application of wireless sensor networks. Reduction of the energy consumption problem is the key to developing WSN. In the cluster based of energy-efficient method, the fixed cluster head number, the energy of node and the transmission distance are the keys to extending the network lifetime. We propose an improved grouping protocol...

In a three-year longitudinal study 471 children were classified, based on their performances on arithmetic tests in first and second grade, as having persistent arithmetic disabilities (AD), persistent low achieving (LA), persistent typical achieving, inconsistent arithmetic disabilities (DF1) or inconsistent low achieving in arithmetic. Significant differences in the performances on the magnit...

Control charts are used to identify the presence of assignable cause of variation in the process. Non-parametric control chart is an emerging area of recent development in the theory of SPC. Its main advantage is that it does not require any knowledge about the underlying distribution of the variable. In this paper a non-parametric control chart for controlling variability has been developed. I...

An important part of dialogue management in a dialogue system is topic management: The system has to keep track of topic aspects (current topic, context, obligations, : : : ) in order to be able to resolve ambiguities and to respond in a cooperative and sensible way. In the schisma project, we are developing a system that takes part in a conversation about theater performances and is able to ma...

Global clustering has rarely been investigated in the area of spatial dambase systems although dramatic performance improvements can be achieved by using suitable techniques. In this paper, we propose a simple approach to global clustering called cluster organization. We will demonstrate that this cluster organization leads to considerable performance improvements without any algorithmic ovedxa...

In this paper, we focus on the synthetic understanding of documents, specifically reading comprehension (RC). A current problem with RC is the need for a method of analyzing the RC system performance to realize further development. We propose a methodology for examining RC systems from multiple viewpoints. Our methodology consists of three steps: define a set of basic skills used for RC, manual...

The present study examines the benefits of instructional animations in a collaborative learning situation. We investigated the interactions that occur during collaborative learning from different materials: animated versus static pictures, both with or without persistency of information. The animation factor had no effect on the types of interactions but the persistency of information led to fe...

Many people are trying to be smarter every day. How's about you? There are many ways to evoke this case you can find knowledge and lesson everywhere you want. However, it will involve you to get what call as the preferred thing. When you need this kind of sources, the following book can be a great choice. computer performance engineering 7th european performance engineering workshop epew 2010 b...

Performance prediction has the potential of ameliorate the student model of an Intelligent Tutoring System by predicting whether a student mastered or not a specific set of skills. Recently, it has been shown, by means of a simulated learning process, how performance prediction methods based on Matrix Factorization can be used for continuous score prediction and for sequencing contents through ...

A biopsychosocial role theory has been developed to integrate the mam findings of psychodynamic, cognitive, and interpersonal therapies. To function in a society, you must achieve a balance between your self-expectations and your performances, and your expectations of others and their performances. These expectations of self and others fall roughly into 16 biopsychosocial areas, or life vectors...
