For the incomplete data that usually exists in the process of pretreatment, this article presents an approach for treatment of the incomplete data based on WaveCluster and weighted 1-Nearest Neighbor (1-NN).The proposed method firstly carries out the WaveCluster in the complete record set of the whole set, which can reduce the volume of comparative data and rule out outliers, improve computational...
During the last decade, using parallel and distributed system has been more general. In these systems a huge size of data or computation is distributed between many systems for getting better performance. Dividing data is one of the challenges in this type of system, because efficiency of system has direct relation to distributed data. One of proposed method for managing data distribution called Divisible...
In this paper, we propose a new routing algorithm which can increase the network lifetime. We assume that each node can estimate its residual energy and then a new clustering method will be proposed for increase of network lifetime. This assumption is similar to many other proposed routing algorithms for WSN and is a possible assumption. In the new method, the predefined number of nodes which have...
Based on whether the Chinese and the U.S. interest rates and exchange rate agreeing with covered interest rate parity theory or not, Granger causality test and co-integration test were utilized to analyze Chinese and the U.S. interest rates and exchange rate from the perspectives of the relation and the transmission mechanism of them. The research found that, without regard to institution and economic...
The use of multimedia technologies in education has enabled teachers to simulate final outcomes and assist students in applying knowledge learned from textbooks, thereby compensating for the deficiency of traditional teaching methods. Thus, it is important to examine how effective these technologies are in practical use. The current study developed online learning-teaching resource platforms using...
Multimedia is an increasingly important part the mix of applications that users run on personal computers and workstations. The requirements placed on a multimedia operating system are demanding and often conflicting. After studying multimedia characteristics and multimedia system requirements, this paper presents a new operating system for multimedia files and applications and it calls this operating...
In order to identify the inverse model for nonlinear dynamic systems, a multiple support vector machines (MSVM) based method was presented. According to their differential orders for the dynamic system, the input and output variables were allocated into multiple calculational subspaces. Taking advantage of its nonlinear regression performance, each subspace was represented by the least squares support...
This study was to create a forecasting model for evaluate freshmen's ability to succeed with using the longest rules from CARs technique as called a particular full-scaled class association rules (PFSCARs). The purposed of this study was to create a classifier tool to evaluate freshmen's ability. This study used demographic data of students in Information Technology program Chandrakasem Rajabhat University...
During the last decade, using parallel and distributed system has been more general. In these systems a huge size of data or computation is distributed between many systems for getting better performance. Dividing data is one of the challenges in parallel and distributed system. One of proposed method for managing data distribution is called Divisible Load Theory (DLT). Ten reasons for using DLT have...
Selecting projects is an important problem, yet often difficult task. It is complicated because there is usually more than one dimension for measuring the impact of each project and especially when there is more than one decision maker. This paper considers a real application of project selection for telecommunication projects with using the opinion of experts by one of the group decision making model,...
In this paper we have proposed a method for lungs nodule detection from computed tomography (CT) scanned images by using Fuzzy C-Mean (FCM) and morphological techniques. First of all, fuzzy have been used for automated segmentation of lungs. Region of interests (ROIs) have been extracted by using 8 directional searches slice by slice and then 3D ROI image have been constructed. A 3D template has been...
WMNs are low-cost Internet access networks built on cooperative routing over a backbone composed of stationary wireless routers. In hybrid mesh WMNs both client mesh and backbone has ability to forward the data to destination. Many ad hoc routing protocols have been adapted to work in WMN without considering the differences between both technologies. Due to the differences between ad hoc network and...
