Power rectifier unit can realize converting current by use of three-phase synchronous rectification bridge. The multiple parallel power units can amplify the capability of single generator and it is invaluable in battery charge, welding machine and electrochemistry fields. Nevertheless, the electromagnetic interference (EMI) which results from the speedy switch of power devices would affect the...

In the present work, some tests on electromagnetic interference issues of a new designed and constructed axial flux permanent magnet generator have been presented. The machine itself has multiple special laminated cores (i.e., 12) 24 windings in stator component with two active sides. Machine operates 3 phases uses disc type magnets rotors at sides sandwiched formation. Rotors 32 freely rotates...

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...

the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

The rapid success of wireless radio communication has shaped several aspects of our social and work lives. This success is still far from reaching its full potential: with the advent of the Internet of Things, future trends indicate an exponential increase of wireless devices for machine-to-machine communication. Due to the broadcast nature of the shared medium, wireless transmissions are poten...

Support Vector Machines (SVMs) have been successfully applied to solve a large number of classification and regression problems. However, SVMs suffer from the catastrophic forgetting phenomenon, which results in loss of previously learned information. Learn have recently been introduced as an incremental learning algorithm. The strength of Learn lies in its ability to learn new data without for...

Machine to Machine (M2M) communications have been recently introduced as a viable paradigm for allowing low cost and efficient communications among devices mainly in an autonomous manner. Even if M2M protocols need dedicated resources, a new paradigm, called Cognitive M2M (CM2M) communications, has been recently considered exploiting cognitive/opportunistic radio communications. After having in...

Recently, video based flame detection technologies have become an important approach to the early detection of potential fire disasters. The recognition accuracy of most of the existing approaches for video based flame detection is not satisfactory. In this paper, we develop a new video based flame detection algorithm that can accurately recognize flames in video sequences based on color and ge...

Support Vector Machine ( SVM ) is widely applied to fault diagnosis of machines. However, this classification method has some weaknesses. For example, it can not separate fuzzy information, particularly sensitive to the interference and the isolated points of the training samples. Besides, it has great demand for memory in calculation. In view of the problems mentioned above, a binary tree-base...

The aim of this paper is to treat the analytical solution of the truncated interarrival hyperexponential machine interference queue: H2/M/1/m+Y/m+Y in case of two branches with the following concepts: balking, reneging, state-dependent, spares, and an additional server for longer queues. Our research treats the general case for the values of m and Y considering the discipline FIFO. And some spe...
