Sensor networks usually generate mass of data, which if not structured for future applications, will require much effort on analytical processing and interpretations. Thus, storing sensor data in an effective and structured format is a key issue in the area of sensor networks. In the meantime, even a little improvement on data storing structure may lead to(More)
,mehdi gheisari 5 * varamin university of science and technology, Abstract—The creation of small and cheap sensors promoted the emergence of large scale sensor networks. Sensor networks allow monitoring a variety of physical phenomena, like weather conditions (temperature, humidity, atmospheric pressure ...), traffic levels on highways or rooms occupancy in(More)
Due to the high volume of information and electronic documents on the Web, it is almost impossible for a human to study, research and analyze this volume of text. Summarizing the main idea and the major concept of the context enables the humans to read the summary of a large volume of text quickly and decide whether to further dig into details. Most of the(More)
Payam Porkar et al. A new method to distinguish patterns of lasiked eyes, ABSTRACT These days intelligent systems have variety of usages in classifying complicated patterns in medics, industry and other fields. Problems as local minimums and etc. In these systems have made them less practical, likewise statistical methods are used to real execution. This(More)
Synthesis of heat exchanger networks (HENs) is inherently a mixed integer and non linear programming (MINLP) problem. Solving such problems leads to difficulties in optimization of continuous and binary variables. This paper presents a new efficient and robust method in which structural parameters are optimized by G.A. and continuous variables are handled(More)
Ontology is a discipline that has a potential improvement to information categorizing, management of information, and interpretations. The goal of ontology is representing knowledge in a way that software agents can interpret and understand data. In this paper we review important concepts of ontology creations and their related taxonomies for creation of(More)
