Diabetic retinopathy (DR) is a major microvascular complication of diabetes. Around 95 million individuals worldwide suffer from DR. Regular testing of fundus images and early identification of initial diabetic retinopathy symptoms, namely microaneurysms and hemorrhages, are essential to decrease vision impairment possibilities. This research work is focused on the detection and classification of fundus images of diabetic retinopathy. In this research work, we have proposed a deep learning-based method to classify diabetic retinopathy fundus images into positive (diabetic) class and negative (normal) class. The convolutional neural network is recently most popular in the computer vision for pattern recognition and classification. In this work we have used pre-trained ResNet50 for the fundus image classification. ResNet50 has amazing power to extract robust and discriminating features from the images for diagnosis. The evaluate the performances of the proposed approach we use publically available Messidor dataset. The proposed approach achieves accuracy of 91.78 % and sensitivity of 94.68 %.

The control techniques play a major role in the systems used to produce electricity from wind source. One of the important functions of the control systems is to determine the active and reactive powers supplied by the wind turbine to the grid. Conversely, the performance of the Wind energy conversion system (WECS) is affected by the varying grid condition. This paper presents a new application of bat optimization algorithm (BOA) to optimally design the proportional plus integral (PI) controllers of the interface converters of permeant magnet synchronous generator (PMSG) – based wind turbine. The PMSG based on wind turbine is connected to the grid via a generator side converter, a DC link capacitor, and a grid side inverter. The response surface methodology (RSM) is implemented to model the voltage specification like undershoot, overshoot, steady state error and settling time. Multiple runs are performed on PSCAD program to create the RSM model. The BOA is applied to the RSM model to minimize the objective function. The simulation results are carried out using PSCAD program. The BOA results are compared with that obtained by using the grey wolf optimization (GWO) results.

Congestion control protocols for background data are commonly conceived and designed to emulate low priority traffic, which yields to transmission control protocol (TCP) flows. In the presence of even a few very long TCP flows, this behavior can cause bandwidth starvation, and hence, the accumulation of large numbers of background data flows for prolonged periods of time, which may ultimately have an adverse effect on the download delays of delay-sensitive TCP flows. In this paper, we look at the fundamental problem of designing congestion control protocols for background traffic with the minimum impact on short TCP flows while achieving a certain desired average throughput over time. The corresponding optimal policy under various assumptions on the available information is obtained analytically. We give tight bounds of the distance between TCPbased background transfer protocols and the optimal policy, and identify the range of system parameters for which more sophisticated congestion control makes a noticeable difference. Based on these results, we propose an access control algorithm for systems where control on aggregates of background flows can be exercised, as in file servers. Simulations of simple network topologies suggest that this type of access control performs better than protocols emulating low priority over a wide range of parameters.

Fraudulent behaviors in Google Play,the most popular Android app market,fuel search rank abuse and malware proliferation. To identify malware, previous work has focused on app executable and permission analysis.In this paper,we introduce Fair Play,anovel system that discovers and leverages traces left behind by fraudsters, to detect both malware and apps subjected to search rank fraud. Fair Play correlate sreview activities and uniquely combines detected review relations with linguisticand behavioral signals gleaned from GooglePlay appdata(87Kapps,2.9Mreviews,and2.4Mreviewers, collected over half a year),in order to identify suspicious apps. Fair Play achieves over 95% accuracy in classifying gold standard datasets of malware, fraudulent and legitimate apps. We show that 75% of the identified malware apps engagein searchrankfraud.Fair Play discovers hundreds off raudulent apps that currently evadeGoogleBouncer’s detection technology. FairPlay also helped the discovery of more than 1,000 reviews,reported for 193 apps that reveala new type of“ coercive” review campaign: users areharassed into writing positive reviews,and install and review other apps.

The process of examining biological tissue under a microscope for detecting the severity of the disease is called histology, it is an essential technique in biomedical research and clinical practice. While slide preparation and imaging is increasingly becoming automated, but the analysis of histology images still require the trained eyes of a pathologist to examine under a microscope. Processing tissues from histopathological images has become now fully computerized, significantly increasing the speed, the labs can produce tissue slides for viewing images digitally. Digitizing these slides, allows pathologist to view these slides on a computer rather than on microscope. routine analysis of tissues selection will be very difficult, manual task that can be completed only by trained pathologists at a huge cost. In the clinical domain, these methods could improve the accuracy and consistency of diagnoses and hence pathologists can focus on the most difficult cases. This research domain could complete the tasks that are time-consuming for humans, and discover new diseases from millions of whole-slide images (WSIs) or precisely delineating tissues within a tumor, allowing for a quantitative comparison of tumours grown under different conditions.
