A novel BIST structure is presented which can greatly reduce the test power dissipation without losing fault coverage. Single input change test pattern is generated by a counter and a gray encoder. The built-in test vectors are generated by the single input change patterns which are exclusive-ORed with seeds generated by the modified LFSR. All test vectors will be single input change patterns during...
In order to meet the requirement of magnetic suspension bearings for high speed machine, the three-level PWM switching power amplifiers are designed and tested. The carrier triangular wave phase shift method is used in the design. The comparative study on the three-level PWM switching power amplifier with the two-level PWM switching power amplifier indicates that the three-level PWM technique can...
A fuzzy sliding mode controller based on radial basis function neural network (RBFNN) for permanent magnet synchronous machine (PMSM) is investigated in this paper, in which direct torque control (DTC) concept, variable structure control and space vector modulation (SVM) are integrated to achieve high performance. Fuzzy logic is used to adjust the gain of the corrective control of the sliding mode...
The gyro stabilized platform control is required to isolate the line of sight (LOS) from the disturbance and vibration of carrier and ensure pointing and tracking for target in electro-optical tracking system. A compound adaptive fuzzy PID control with hysteresis-band switching is developed for this servo system with nonlinear property and some uncertainties. Here, in the adaptive fuzzy controller,...
This paper shows a new DNS attack that hijacks DNS requests by frequently injecting fake DNS server, and then network systems communicate with wrong destinations. This type of attack is detectable by neither the IDS nor any anti spoofing software.
The demand for high-performance embedded signal processing systems has expanded rapidly in recent years. As applications requiring faster computation capability, higher throughput bandwidth and more flexible interconnection, traditional embedded signal processing systems could not meet the demand of ever-increasing performance. The paper designs a high-performance heterogeneous embedded signal processing...
With the development of the computer science and information technology in the field of automatic control, data acquisition system and the combination of analysis and processing system has been in a wide range of applications. This paper discusses the NI-DAQ-based data acquisition integration of the hardware and the software to establish a complete set of virtual instruments and equipment, and conduct...
Here introduces a monitor system technically based on ARM7 embedded micro processor (HMS30C7202) and Micro C/OS-II embedded operating system. The paper provides the scheme of the principal, introduces the connection method of outside signals, tells about how to transplant the Micro C/OS-II to the operating system, and shows the programming emphases and some source code of the majority of the program.
In this paper, we proposed a dual flit transmission rate (DFTR) router architecture according to the property of short distance for the inter-wafer links for 3D Network on Chip (NoC). The equivalent bandwidth of the inter-wafer links can be N times wider than that of the intra-wafer links, since flit transmission rate in vertical direction can be N times fast than that in the horizon direction. Thus,...
A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. Compared to wired networks, MANETs are more vulnerable to security attacks due to the lack of a trusted centralized authority, easy eavesdropping, dynamic network topology, and limited resources. This paper introduces a intelligent secure routing model for MANET. The intelligent...
this paper shows the design and implementation of a video capturing and processing system, which can collect plate-profile information and process image in the spatial domain. Strategy of buffer storage is used in the collecting part; read and write two SRAM at the same time to improve the data throughput. In the processing part using Synchronous FIFO to implement sliding window whose function is...
The packer switching service of the third-generation mobile communication network (3G) has provide a broader range of services, while wireless local area network (WLAN) has a faster speed in information transmission, thus making these two complementary functionally. However, with the improvement of technology and increasing of mobile users, it has a significant impact on network communication when...
In this paper, the advantages and disadvantages of traditional PID controller and fuzzy logic controller algorithm were analyzed on the control characteristics of electric furnace. According to the intelligent control theory, fuzzy PID (Fuzzy-PID) compound control was selected to realize intelligent control of electric furnace with two-input and two-output system. Based on real temperature control...
This paper presents an innovative procedure, capable to automatically generate virtual environments which are applicable to art galleries, museums or similar facilities, and suitable for web-based promotions of artists and their works. The presented system is part of the outcome of an interdisciplinary research for low-cost and platform independent solutions to combine art with virtual reality with...
GPS is widely used in vehicle location. But it has many restrictions in underground parking or built-up place. So, we proposed an dual-mode approach based on GPS and GPSOne. At first, we make researching on the dual-mode switch positioning technology, and then set the judging criteria. Finally, provide the method of switching by engineering mathematics. It provide a good way to solve the blind spot...
We have already some technologies to perform these types of application such as: Bluetooth, IR. However these are used in a limited area which we can easily come over in the proposed system. This system has two sections one is Remote Section (RS) where the client will place the request and another is Local Section (LS) where the telephone line is connected with an Input Interfacing Circuit (IIC)....
Since online education service emerged at the end of the 1990s, it has been expected to reduce the cost of traditional education and finally could replace some parts of the offline education markets. Unlike the initial expectation, however, online education market is not growing up fast. In order for online education service providers to maintain and increase the number of users, which factors make...
Nowadays, many industries use the Computerized Numerical Control (CNC) for Printed Circuit Board (PCB) drilling machines in industrial operations. It takes a long time to find optimal tour for large number of nodes (up to thousands). To achieve more effective results, optimization systems approach is required to be equipped in drilling machine. Euclidean Traveling Salesman Problem (TSP) is one of...
The central air-conditioning system has a great delay, and the flow of people changes quickly at large shopping malls, so the traditional control model which is based on the instantaneous change of the parameters has a limited energy-efficiency effect. In order to enhance the operation efficiency of the central air-conditioning system, the control strategy should be changed. Based on the conservation...
SCADA is an acronym for Supervisory Control and Data Acquisition. SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy. A typical SCADA system comprises of I/O signal hardware, Controllers, software, network & communication. Supervisory control and data acquisition system is a system in which message or commands...
