The filter bank multicarrier (FBMC) with offset quadrature amplitude modulation (OQAM) is appreciated for its well-localization in time-frequency domain. However, the major drawbacks of FBMC is high peak to average power ratio (PAPR). In this article,we extend the idea of Discrete Fourier Transform(DFT) spreaded based FBMC scheme theoretically and address the theoretical analysis of the PAPR of the DFT-spread FBMC transmitted signal. The simulation results show that the proposed scheme achieves substantially lower PAPR, low PSD leakage and lower BER than the previous FBMC scheme. We also theoretically derive the expression of the PAPR of proposed scheme. Finally, this paper highlights the strengths and weaknesses of FBMC and DFT based FMBMC

Udemy and Nptel are online learning platform where learners get access to wide variety of courses. These platforms have 2 issues which we aim to solve. First, Currently in Udemy the questions asked in discussion forum are not divided based on course videos, i.e. there is common discussion forum where question with respect to any content in the course can be asked. This is problem because, when a new question is asked all the question in the discussion forum have to be compared with the new question for similarity. This can take up significant amount of computational time. To avoid this we have applied Random Forest classifier to find out the category of a newly asked question (with respect to Udemy it would mean finding which video the question relates to), if category is found only previously asked questions in the particular category are compared for similarity rather than the previously asked questions in the whole database. Second, Currently NPTEL is not course coordinator friendly. This is because lots of times there is redundancy in the questions asked, this is burden on the course coordinator because he/she has to answer to each and every version of the same question. This has been tackled by using techniques like GBDT, SVM to detect semantic similarity of questions. The Random Forest classifier achieved accuracy of nearly 73% and GBDT achieved accuracy of nearly 64%.

This paper exercises fuzzy logic for the prediction of channel response to a two dimensional-wavelength hopping /time spreading optical code division multiple access (2D-WH/TS OCDMA) code in a passive optical network (PON). A fuzzy logic control (FLC) is employed for the reduction of bit error rate of 2D-WH/TS OCDMA PON at the receiver. This FLC predicts the environmental temperature variation effects that occur in the transmission links which impact the expected magnitude of the autocorrelation peak of 2D-WH/TS OCDMA code at the receiver. The FLC system, uses propagation distance and the temperature changes in channel which is estimated by sensors, as input variables, to predict the auto-correlation peak at the receiver. This information on the reduction of auto correlation requires to dynamically adjust the threshold level of threshold detector at the receiver. The design of the FLC demands a priory knowledge of the analytic response of the 2D-WH/TS OCDMA channels. The simulation of FLC was done by using membership functions in MATLAB using fuzzy libraries. The simulation results show that the effect of environmental temperature can be predicted with the accuracy of 92.1% from the analytic model available for channel response.

The integration of renewable energy into the grid has become a challenge and faces two fundamental technological problems, namely variability and location. As renewable resources are focused far from the customers, it requires extra-long length, high-capacity transmission to coordinate the supply with the demand. It is essential to recognize the fluctuation and the vulnerability when examining and anticipating the tasks of the power grid. The test of the changeability can be met by exchanging conventional generation goal in or out in response to the possible estimates of weather by forecast and schedule deviation settlement mechanism (DSM). The deviation settlement mechanism is a penalty to the generator who under injects or over injects power into or outside the state with a buffer limit to bring awareness to the generator so that the forecast generation almost meets the actual generation taking the accuracy & AvC into account, in this paper the DSM calculations for inter and intra state has been shown and the comparison between less and more deviation pattern is shown for both solar and wind substations.

Electrocardiogram (ECG) is a vital signal which represents the state of health of astronauts in a manned spaceflight mission and hence must be continuously acquired and transmitted throughout the mission. Telemetry bandwidth is a premium resource in such applications. Traditional method of sampling at Nyquist rate is highly bandwidth inefficient. Hence it is advantageous to use Compressive sensing (CS) technique to optimize data at measurement point itself. Conventional CS techniques employ computationally intensive measurement matrices which are not hardware efficient for both acquisition as well as recovery. In this work, a hardware efficient scheme with use of a sparse binary measurement matrix is proposed. The signal is recovered from the compressive measurement using a constraint function based on inverted Laplace distribution function. Gradient decent method is used to recursively recover the original ECG signal from the compressive measurements in an efficient manner. Apart from this, a projection scheme is also proposed to minimize the recovery error. The proposed scheme was extensively evaluated with different ECG samples with different compression ratios. Finally, the proposed scheme was benchmarked with Approximated L0 norm based method and it is found to perform more efficiently in compressively sensing and recovery of ECG signals.

Navigation in outdoor and indoor is certainly an challenging task for visually impaired, blind and deaf-mute people, indoor navigation itself is certainly becoming an harder task for blind, visually impaired people and dead-mute people. As far as observed for the non-visually impaired, it is even worse for the visually impaired. People with visual disabilities or blinds are often depending up on external assistance like trained dogs, humans, or special devices as support systems for making decisions. Hence blind people need an assistive device that will allow blind user to navigate freely and this requirement has become crucial. Here the interfacing of different sensors and actuators along with Braille keypad which is user friendly application to these peoples is done with ARM LPC-2148 and it helps in minimizing the problems faced by blind people by maximizing the use of technology. The walking stick used by the blind people has multiple sensors incorporated in it, with the help of which it is possible to enhance more features and technology to the walking stick. The main features are to detect the obstacle for collision avoidance, along with certain other sensors for pit whole detection, fire detection, and water detection. Panic switch is the emergency button that sends an SMS from the GSM module to the caretaker with the present particular location (GPS coordinates) of the blind, visually impaired and deaf mute person. The work goes for giving the safest route to blind persons, visually impaired person or deaf-mute person, by designing a more flexible assistance system and cost effective system that helps them in improving their navigating skills in outdoor and indoor application and also not to depend on none during walking in even unknown areas.

Among the generally occurring common skin cancer, Melanoma is said to be the most dangerous type of cancer. Many of the Computer vision techniques have adapted to detect the disease early days. In the similar way this paper proposes an image pattern classification to identify skin disease in images with a combination of texture and color feature extraction. The main aim of this paper is to find appropriate features that can identify skin disease. Initially, normal and diseased images are collected and pre-processed by converting the images into Grayscale by PCA and multilevel Otsu thresholding. In addition the post processing includes dilation and erosion techniques and canny edge detection for quantization. Then features of shape, color and texture are extracted from the images and these images are classified by support vector machine classifier. A combination of several features is used to evaluate the appropriate features to find distinctive features for identification of disease. When a single feature is used, shape feature has the lowest accuracy of and texture feature has the highest accuracy. A combination of texture and color feature extraction results highest classification accuracy.

This paper intends a fast and efficient cryptosystem based on confusion and Henon chaotic diffusion. The algorithm encrypts an image in two stages. In the first stage, the original images is transformed using Pseudo Hadamard transformation (PHT) along with substitution image. The key length used in the algorithm is 128 bits. These secrete key digits are used as initial conditions for Henon chaotic generator. A substitution box (S-box) is constructed using random sequences generated by chaotic generator. The cipher image from confusion stage is then subjected for diffusion using S-box. Based on the results obtained from differential and analytical tests, the proposed algorithm can withstand such security attacks compared to existing systems.

Recently, power gating technique is being adopted in many designs for minimizing power consumption (MTCMOS). This paper mounts new hybrid-logic circuit design for inverted 4–16 decoder invented using sleep transistor capable of lowering power dissipation and power-delay product(PDP). Two circuit designs are proposed here using DEC-14 topology and DEC-15 topology at supply voltage of 1V and 10MHz frequency. Also, pulse input is provided to sleep transistor for switching action at 10MHz frequency. Employing this technique, considerably reduces leakage power, benefitting circuit design by improvising its key parameters. Later, various simulations results are represented on 32nm technology showing brief comparison between distinct circuits.

With bulk CMOS technology scaling below 100 nm, there is significant increase of leakage power in that. Multigate FET like FINFET and CNTFET (carbon Nano tube field effect transistor) are the devices to replace that because of improved drive strength and short channel behavior. This paper represents dual supply voltage level shifter which is capable of converting low input of voltage to high level. This proposes a comparative study of voltage level shifter at 32nm technology node of MOSFET, FINFET and CNTFET. Simulations results tells us that there is notable improvement at frequency 0.5Mz in average power and PDP of 7.50E-07 W and 3.57E-14 in FINFET and 9.58E-07 W and 2.45E − 14 in case of CNTFET with comparison of MOSFET.
