A biosensing platform based on a nanocavity-coupled photonic crystal waveguide (PCW) is proposed for diseased cell detection. The proposed label-free waveguide-cavity-coupled nanostructure with high-$Q$ is designed and analyzed to exhibit high sensitivity and high selectivity against five different cancer cells. The introduction of a nanocavity in the PCW leads to a sharp resonance that makes it...
To improve the power quality based on T-transformer (T-connected) and a 3-leg VSC a 3-phase 4-wire DSTATCOM has been proposed in the paper. The Transformer(T-connected)connection is used to reduce current (neutral) while compensation of power(reactive power) and load balance is done with 3-leg source converter (voltage). The dc voltage regulation of voltage source converter is done using various loads...
Microarray technology is one of the emerging technologies in the field of genetic research, which many biologists often use to monitor expression levels of genes in a given organism. Microarray experiments are used to investigate genome-wide expression changes in health care aspects. The colossal amount of raw gene expression data often leads to computational and analytical challenges including feature...
Cellular heterogeneous networks (HetNets) are going to be one of the key enablers for 5G. Downlink/Uplink decoupling (DUDe) is a concept in which a mobile device is connected with Macro cell for downlink communication and with small cell for uplink communication in LTE/LTE-A HetNets. It improves uplink data rate, reduces power consumption of devices, balances load between Macro cell and small cells...

This paper describes design and development of single disc RF window for high power Gyrotron. The electrical design of edge cooled single-disc alumina window for 170 GHz, 1MW short pulse Gyrotron has been carried out using CST microwave studio. A diameter and thickness of the ceramic window are 90 mm and 3.16 mm, respectively, whose edge is directly cooled by water. The return loss (S11) and insertion...
A multiband compact terahertz antenna on silicon-on-insulator (SOI) based on 1D photonic crystal is proposed. It is shown that the multi-resonance of terahertz waves in a copper patch on SOI can be effectively controlled with photonic crystals on the patch. The proposed antenna is shown to work for 13 frequency bands with acceptably low return losses in terahertz regime. The photonic crystal assisted...
This paper presents an earnest attempt on the development of solar cells mainly, high efficient solar cells which are very much needed for the development of photovoltaic industries in India. CuInGaSe2 thin film solar cells have a potential for highest efficiencies on the laboratory scale as well as on the level of large area modules. The role of intrinsic defects in CuInGaSe2 and their implication...
Posture is a way in which a human holds his body so that there is less strain on muscles during movement. Poor body posture leads to many health issues. Incorrect posture problems, which range from back pain to fatigue may rise up and affect our daily activities. The Nowadays maximum population suffers from back pain, injuries, neck pain and shoulder problems etc., hence a need to develop a device...
In MANET nodes are power constrained, for the reason that nodes has operated with limited battery energy or power. The nodes in network are not communicated with each other because of early depletion of mode energy. The nodes which are completely lost their energy in network are not possible to further communicate with other nodes without the replacement or charge the battery of node in dynamic network...
In this work, the effects of reshaped specta of different schemes such as NRZ (Non return to zero), Dicode-NRZ and Duobinary on Wavelength division multiplexing have been analysed for two wavelength 1550 & 1551 nm with the system capacity of 80 Gbps. For a system with the capacity of 80 Gbps is achieved by wavelength division multiplexing of two 40 Gbps channels and fixed fiber length of 50 km/span...
A grating based hybrid plasmonic waveguide with subwavelength optical confinement and larger propagation length is proposed. The grating assisted low-loss guiding of hybrid plasmonic-photonic mode is achieved with high nonlinearity of 18.7 × 107 km−1w−1. An acceptably low propagation loss of 4 dB/mm and hence a large propagation length of 1027-μm with modal area of 0.00017/μm2 are reported.
Use of power electronic converters with nonlinear loads produces harmonic currents and reactive power. An active power filter will only provide the solution for these two problems by giving the compensating current to the supply time to time. However, the shunt active power filter with PI type of controller is suitable only for a given load. If the load is varying, the proportional and integral gains...
In this work, we analyzed the effects of partial response coding (balance duobinary and dicode coding) in the presence of nonlinear effects. By simulation, we find that the balance duobinary coding is more affected by stimulus Raman scattering (SRS) by an amount of 0.5 dB as compare to dicode coding. So, dicode coding comparatively more tolerance to Raman cross talk in the video Overlay Passive Optical...
Microarray dataset often contains huge number of data, only a fraction of which comprise significant differentially expressed genes. In this article, t-test is applied to identify the precise and interesting genes which are responsible for cause of cancer. After precise identification, a new embedded approach is proposed where in a genetic algorithm (GA) is combined with Artificial neural network...
Broadband Power Line Communication (BPLC) technology, offers a convenient, efficient and reliable medium for high frequency-data transfer for broadband access, by creating networks within existing infrastructure. As the powerline network is very noisy, complex and varying from place to place, it is very difficult to model the channel. For creating a new efficient power line communication model of...
This paper presents a text-mining based approach to detect cross-site scripting (XSS) vulnerable code files in the web applications. It uses a tailored tokenizing process to extract text-features from the source code of web applications. In this process, each code file is transformed into a set of unique text-features with their associated frequencies. These features are used to build vulnerability...
