Abstract: This paper presents a new approach for image segmentation by applying k-means algorithm. In image segmentation, clustering algorithms are very popular as they are intuitive and are also easy to implement. The K-means clustering algorithm is one of the most widely used algorithm in the literature, an...     Read More

Abstract: Ad Hoc network Consist of mobile hosts (or nodes) which communicate with other nodes through wireless medium without any fixed infrastructure. Dynamic network topology: the mobile nodes are free to move randomly and organize themselves arbitrarily the wireless links in this network are highly error ...     Read More

Abstract: Wireless local area networks(W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates.The IEEE 802.11a standard is WLAN standard which uses orthogonal frequency division multiplexing technology.The standard pro...     Read More

Abstract: Mobile Ad-hoc networks are a collection of mobile hosts that communicate with each other without any infrastructure. Due to security vulnerabilities of the routing protocols, wireless ad hoc networks may be unprotected against attacks by the malicious nodes. One of these attacks is the Black Hole At...     Read More

Abstract: This paper presents the implementation of an adaptive edge-detection using Simulink. Simulink is a simulation modeling and design tool and GUI based diagram environment. The Simulink based customizable framework is designed for rapid simulation, implementation, and verification of video and image pr...     Read More

Abstract: This paper proposes a security mechanism for remote monitoring system through a combination between user's password and random number by using SMS service over 3G networks. By using random number and phone number, this mechanism is not only able to provide robust security from replay attack and dict...     Read More

Abstract: Nowadays in every field there is an enormous use of digital contents handled with the help of Internet, Multimedia and Network system in digital form. There are more chances of copying of such digital information, so that the necessity of prohibiting illegal activities. The watermarking is the power...     Read More

Abstract: Karyotyping is a technique used to display and study the human chromosomes for detecting abnormalities, genetic disorders or defects. M-FISH (Multiplex Fluorescent In-Situ Hybridization) provides color karyotyping. In this paper, naive Bayes classification of M-FISH chromosome images based on waters...     Read More

Abstract: The design of OTA based low pass filter for video applications in Broadband Communication is described in this paper. A low-pass, fifth-order Chebyshev filter based on the Folded Cascode Operational Trans conductance Amplifier in0.18 um CMOS process is designed.Folded Cascode OTA is chosen as it all...     Read More

Abstract: The cardiovascular disease is number one killer of the world for both men and women. The ECG signal is mainly used to monitoring this type disease. In this paper proposes the compression of ECG signals and provide the encryption for that signals. The encryption technique of ECG signal is used to pro...     Read More
