Robustness of modern ICs during system assembly and normal operation requires that protection circuits are built-in to prevent damage to internal circuit elements due to Electrostatic Discharge events (ESD), which can inject substantial energy into the chip. ESD protection as well as protection against other damaging events, such as latchup, is highly dependent on chip architecture and circuit design,...
A novel high speed and tunable transconductor suitable for analog and mixed-signal fuzzy circuits operating in current mode and a high linear MIN circuit are proposed. Using this OTA, we construct are high speed Gaussian and trapezoidal-shaped fuzzifier and implement S-shaped and Z-shaped function with all parameters (slop, width, and position) independently and continuously tunable, and excellent...
In this paper, we investigate characteristics of output values by a proposed new system of two layer cellular neural networks (two-layer CNN). In a general way, image processing of using conventional cellular neural networks is still image processing. On the other hand, it is few for motion picture processing. Therefore, we propose the new system which is effective structure for motion picture processing...
In this paper, the point-to-point control problem of a Prismatic-Revolute (PR) under-actuated manipulator is presented. The PR under-actuated manipulator with the first prismatic actuated joint and a second revolute passive joint can only move in the horizontal plane. According to the characteristic of the dynamic equation of the system, a new equation concerned only with generalized coordinate, velocity...
Multiuser voice conferencing platforms are more and more popular. Internet bandwidth is becoming very accessible, what makes voice over IP used on an everyday basis. Being able to communicate with multiple people at the same time can be beneficial, but on the other hand increases the need of coordination mechanisms. Determining a moderation scheme which is fair and efficient is not a trivial problem...
A ball-on-plate balancing system, the ball and plate, has a camera to catch a ball position and a plate whose angle of inclination is limited. This paper proposes a design method of PID control based on the generalized Kalman-Yakubovich-Popov lemma for the ball and plate. The design method has two features: the first one is that a structure of the controller is called I-PD to suppress a large input...
On the basis of a kinematic third order nonlinear model of an autonomous vehicle, a space-learning control is designed for the tracking of planar curves whose uncertain curvature is L-periodic in the curvilinear abscissa. The behaviour of a human driver, who repetitively learns the correct action from the past experience, is mathematically reproduced. Simulation results demonstrate the effectiveness...
The paper illustrates through the example of a mobile robot how discretization makes easier the design of a predictor based stabilizer for nonlinear dynamics with delayed input admitting finite sampled equivalent models.
This paper presents a novel process, voltage and temperature (PVT) invariant voltage reference generator using subthreshold MOSFETS. The proposed circuit uses weighted average of PTAT and CTAT voltages at zero temperature co-efficient point. The proposed circuit has been designed and optimized in 180nm mixed-mode CMOS technology. Simulation results show that the output voltage of the proposed voltage...
Leon O. Chua introduced the memristor as the fourth circuit element to complete the set of fundamental passive two-terminal elements in 1971. For a long time it seemed as if memristors were just toys in the sandbox of network theorists. The situation abruptly changed in 2008 when scientists from HP reported on a nanoelectronic device which showed a memristive behaviour. Main hopes for new opportunities...

This paper presents a controller synthesis method to stabilize piecewise-affine (PWA) slab systems based on invariant sets. Inspired by the theory of sliding modes, sufficient stabilization conditions are cast as a set of Linear Matrix Inequalities (LMIs) by proper choice of an invariant set which is a target sliding surface. The method has two steps: the design of the attractive sliding surface and...
With the rising cost of traditional energy, alternate sources of energy like wind energy are being looked into. This ample source of renewable energy is widely distributed, cheap and also helps in reducing toxic gas emissions. Although, wind energy is one of the renewable sources of energy, there are certain constraints which pose a challenge in using it to its full potential. Higher wind speeds will...
We show by the analytical and simulation results that pre-equalized OFDM based on base-field Hartley transform (BHT-OFDM), which is an alternative air interface for LTE-beyond or 5G, provides significantly better PAPR performance than conventional OFDM systems. We develop a tractable analytical closed-form expression of the statistical distribution of PAPR of pre-equalized BHT-OFDM based on correlated...
Wireless Sensor Networks (WSN) which is capable in sensing, storing, processing and transmitting data has been widely applied in providing effective surveillance. Optimum sensor nodes placement in the surveillance area is needed to optimise the cost and efficiency of deployment. The positions of sensor nodes should be able to provide maximum coverage with longer lifetime. This paper proposed a sensor...
Social collaboration scenarios, such as sharing resources between friends, are becoming increasingly prevalent in recent years. An example of this new paradigm is Social Cloud Computing, which aims at leveraging existing digital relationships within social networks for the exchange of resources among users and user communities. Due to their complexity, such platforms and systems have to be carefully...
The perpendicular maneuver under water of submarines is a complex multivariable system with coupling. the depth and pitch control system of submarine is difficult to design for the coupling relationship between the bow elevator and stern elevator. the submarine nonlinear model on the vertical is simplified according to the simulation needs. the bow rudder auto disturbance rejection controller (ADRC)...
Flight Data records the important plane subsystem status, attitudes, actions, key parameters, etc. during whole flight. Visualization of the information extracted from flight data is very useful to replay the entire flight and evaluate the quality. in this paper, we present a general framework to simulate and evaluate the flight course based on flight data processing and visualization.

The dual orthogonal stereo sensor (DOSS) method uses acoustic waves to determine the distance and direction of an object in an underwater environment. A DOSS system is composed of one acoustic signal generator in the center and four acoustic signal receivers in an orthogonal stereo configuration. In this paper, we propose several algorithms with dual orthogonal stereo sensors that measure the range...
