The design of a graphene based nano dipole antenna on stacked substrate is reported. A stack of substrate is formed from two different dielectric substrate materials, each of equal height. The performance of the designed antenna is investigated for three different substrate stacks such as Quartz-Silicon, GaAs-Silicon Nitride, and Polyimide-Glass. For each stack, total substrate height is varied from 80 μm to 120 μm, taking 20 μm as step size. The considered performance parameters of the designed antenna are return loss, bandwidth, radiation efficiency, gain, and directivity at a targeted resonance frequency of 1.02 THz. The simulation results confirm that Quartz-Silicon substrate pair with a height of 100 μm provides the best antenna performance. The enhanced outcomes are compared with other similar graphene antennas to ensure the effectiveness of the proposed design. The attractive properties and significant performances of the proposed graphene antenna make it a potential candidate to be used in wireless communication in nanosystems and THz sensing applications.

Modern world has become more dependent on electronics and hence speed is a major factor in the field of their functionalities. Modern CPUs work lot faster and efficiently than older versions. Still humans require more and more time efficiency in their daily computational works. In this paper, the main focus is on the increase of time efficiency in computing. Hence this paper shows a time performance comparison between FPGA and CPU implementation. In this regard, Booth's multiplication algorithm has been implemented on both CPU and FPGA to compare the running time. The FPGA implementation is found out to be around 9 times faster than that of a modern CPU implementation.

In this paper, the performance analyses of Solid State Dye Sensitized Solar Cells (SSDSSCs) are carried out with power grid integration and off-grid operation in the intertropical region being the main focus. It has been observed that electrodes of different compositions such as: TiO2 and ZnO, surface morphology of the thin films used in SSDSSCs, use of different types of dyes as photo sensitizers, use of Nanorods/Nanoparticles as photoanodes — all correspond to different photoelectric conversion efficiencies (PCEs) in SSDSSCs. As the SSDSSCs are free of leakage and corrosion related problems prevalent in conventional liquid-based Dye Sensitized Solar Cells (DSSCs), it has the potential to lower the maintenance cost and improving longevity of a system, so far however SSDSSCs suffer from low PCEs when compared with conventional DSSCs, with a maximum efficiency record of approximately 15 per cent set in 2013 by using solid-state mesoscopic TiO2 solar cells sensitized with lead iodide perovskite (CH3NH3PM3) pigments[1–4], in early 2014 which was further lifted to 16.7 per cent[26]. Careful selection of highly photosensitive dye in conjunction with proper nanotube photonic crystals can optimize the efficiency of SSDSSCs for the intertropicsl region.

Semi supervised approaches are practical in problem domain where pattern clustering is supposed to provide good classification. Gaussian Mixture Model (GMM) can approximate arbitrary probability distribution, thus is considered as a dominant tool for classification in such domains. This paper appraises the functioning for GMM as it is applied to imbalanced datasets which consists of uneven distribution of samples from all the classes. Later, an ensemble approach is presented to boost the GMMs in a semi supervised manner via Adaptive Boosting technique. Experiment on benchmark imbalanced datasets with different imbalance ratio has been carried out. Empirical result demonstrates the efficacy of the proposed Boosted GMM classifier compared to baseline approaches like K-means and GMM.

Due to rapid depletion of fossil fuel and environment concern, clean and non-polluting energy i.e. renewable energy is highly needed. Among the various renewable resources, wind energy is one of the most important and promising sources. In the recent year doubly fed induction generator (DFIG) is one of the most widely used in wind farms. But the transient stability of DFIG becomes very much sensitive and challenging concern. Three phase line-to-ground fault (3LG) is one of the worst cases of DFIG. During fault at grid side, DFIG is much affected because its stator windings are directly connected to grid. So it is important to analyse the transient stability of DFIG during fault according to fulfil the grid code requirement. To improve the transient stability and fault ride through capability of DFIG a new topology of fault current limiter (FCL) is proposed in this paper. The proposed FCL is not only limit the fault current but also faster voltage recovery. Thus improve the transient stability and fulfil the grid code requirements. For simulation analysis, PSCAD/EMTDC software is used. To determine the advantageousness of proposed FCL, its performance is compared with the conventional series dynamic resistor (SDR). Simulation results show that the proposed FCL enhances the transient stability of DFIG and better performance than SDR.

The acoustic beamformer is an important tool which is used in many environments to focus on a specific sound among many reverberations. This paper presents an acoustic microphone array beamformer in the presence of unwanted signal. Time delay and Frost beamforming techniques are used with microphone array to reduce the noise and cancel the interfering signal respectively. The presented beamformers can be able to increase the system SNR without array mismatch. The performance of the time delay and Frost microphone arrays will degrade in the presence of array imperfections. To improve the system performance a robust algorithm is addressed in this paper. The extensive computer simulation is presented to analyze the performance of the acoustic beamformer with different scenarios.

Energy saving and prolonging mileage are very important for battery-operated electric vehicles (BEV). For saving energy in BEV's the key parts are regenerative braking performances. Permanent magnet DC (PMDC) motor based regenerative braking can be a solution to improve energy saving efficiency in BEV. In this paper, a novel regenerative braking mechanism based on PMDC motor is proposed. Based on proposed method braking can be achieved by applying different armature voltage from a battery bank without using additional converter with complex switching technique, ultra capacitor, or complex winding-changeover. An experimental setup has been used to evaluate the performance of the proposed braking system. Simulated results prove that the proposed regenerative braking technique is feasible and effective. Also this research provides simplest system for regenerative braking using PMDC motor to improve the mileage of electric vehicles.

Energy is essential to life and the major source of energy comes from fossil fuels. As the human population increases, our rate of consumption of these fossil fuels also increases. On the other hand, world population continues to grow and the limited amount of fossil fuels begin to diminish, it may not be possible to provide the amount of energy demanded by the world by only using fossil fuels to convert energy. The solution to the problems of limited fossil fuels and their impact on the environment is to have renewable resources play a larger role in the supply of energy. In this case wind energy is the most promising green energy. As wind turbine output is proportional to the cube of wind speed, the wind turbine generator output fluctuates due to wind speed variation. Thus this paper focuses on the comparative study between conventional wind turbine models with modified pitch controller and proposed a new technique called modified pitch governor with exciter controller to control output voltage and frequency without using any costly energy storage devices. In this study variable load is considered and real wind speed data is taken to obtain realistic response. PSCAD/EMTDC software is used for simulation analyses.
