This paper presents a novel design of ternary D-latch using carbon nanotube field effect transistors. Ternary logic is a promising alternative to the conventional binary logic design technique, since it is possible to accomplish simplicity and energy efficiency in modern digital design due to the reduced circuit overhead such as interconnects and chip area. In this paper novel design of D-latch for ternary logic based on CNTFET, using only basic gates STI, NTI, NOR, NAND and transmission gate, is proposed.

Watermarking the digital data is a familiar technique to authenticate and resolve the copyright issues of multimedia data. This paper proposes a new VLSI architecture for watermarking grayscale images using weighted median prediction operation, as this mechanism will have a minimum computation complexity. In this VLSI based data hiding process the secret digital signature is hidden in the host image and analyzed with the PSNR value and Payload capacity.

This paper is concerned with design of an autopilot for longitudinal flight control of a conventional airplane. There are different modes of automatic longitudinal flight controls. Among those pitch attitude hold, altitude hold and vertical speed hold mode autopilots are implemented in which controller is designed for each of these modes. By the use of this controller, the system performance is improved. The performance requirements such as the peak overshoot to be less than 15% and the rise time to be less than 1 second has been achieved by the use of each controller in different modes. Traditional control techniques such as PID controller and Lead-Lag controllers are designed to each of these autopilot modes. Root-locus design technique is applied for tuning the parameters of each controller. Simulation of autopilots in the presence of three different types of atmospheric disturbances such as Dryden wind gust, Vertical wind gust model and turbulence are also observed. As in effect due to disturbance on each mode, a pitch rate feedback is applied in the inner loop of pitch controller. So a feedback control loop is developed to design the autopilot.

An ideal multi-objective optimization method for economic emission load dispatch (EELD) with non-linear fuel cost and emission level functions in power system operation is presented. In this paper, the problem treats economy, emission, and transmission line security as vital objectives. The load constraints and operating constraints are taken into account. Assuming goals for individual objective functions, the multi-objective problem is converted into a unique-objective optimization by the goal-attainment method, which is then taken care of by the simulated annealing (SA) technique. The solution can offer a best compromising solution in a sense close to the requirements of the system designer. Results for 30-bus, 57-bus, 118-bus IEEE test case system have been utilized to demonstrate the applicability and authenticity of the proposed method.

Testing simple circuits or digital blocks can be actually done easily but testing a complex circuits before it is implemented is a challenge. To accomplish such testing, this paper presents a fault injection technique using package to inject transient and permanent fault at the VHDL level description of both combinational and sequential digital circuits to verify the testability of the circuits using online and offline testing. Injection of permanent fault and transient fault are done in the digital circuits such as 4 bit adder, 4 bit counter, two benchmark circuits C17 and S27 and their testabilities are evaluated. Fault coverage for permanent fault and transient fault is found to be 95% and 100% respectively.

In this paper compact design of planar slot antenna with band-notched function for UWB application is presented. This proposed antenna design explains the method to notch the interfering frequencies in the UWB by loading the small strips over the conventional microstrip patch antenna. To create notch for some narrow bands such as WLAN, WIMAX and X band in the UWB by using slits. This can be done by placing angle shaped slits on the substrate, two symmetrical slits placed on the tapered shaped Ground plane and two narrow slits are etched out on the patch of the antenna. By properly altering the size and location of the slits the proposed antenna design achieves the UWB operation and notch characteristics without altering overall size of the antenna is 22 × 24 × 1.6 mm3. This notch band will help to avoid the possible interference between UWB and these narrow bands. The simulated result gives a good impedance matching, return loss <; -10 dB and VSWR below 2 in the frequency range of 3.1-12GHz (≈9GHz).
