Spatial, temporal, and weather elements like ballast, loose nuts, misalignment, and cracks due to rain, snow, and earthquakes may lead to railway accidents and cause human and financial loss. Manual inspection is erroneous, labor-intensive, and *** automatic inspection provides a fast, reliable, and unbiased solution in this regard, however, ensuring high accuracy for fault detection is challenging due to the lack of public datasets, noisy data, high computer processing requirements, and inefficient models. This study presents an approach that uses Mel frequency cepstral coefficient features from the acoustic data. The dataset gathered using a customized railway cart from our previous research is used for experiments. The focus of the study is to increase the fault detection performance using selective features from the acoustic data. This study employs Chisquare(Chi2) for the selection of important features and involves performance analysis of machine learning and deep learning models using selected features. Experimental results suggest that using 60 features, 40 original features, and 20 Chi2 features, produces optimal results both regarding accuracy and computational complexity. A 100%accuracy can be obtained using the proposed approach with machine learning models. Moreover, this performance is significantly better than existing approaches.

Dear Editor,Crimean-Congo hemorrhagic fever(CCHF),caused by the CCHF virus(CCHFV),is a tick-borne zoonotic infection characterized by myalgia,high-grade fever(>38℃),headache,nausea,bleeding from the body cavities,and in 10%–50%of cases,results in death(Swanepoel et al.1989).As CCHFV belongs to the Nairoviridae family,the virus can be transmitted to humans through the bite of infected ticks or by contact with the tissues or blood of infected animals(Bente et al.2013).

The high speed protection of power system for transmission and primary distribution networks are the most important issue in the selective tripping of the power plant. In order to solve this problem high speed automatic reclosure is continuously in development with state of the art technology used. The economic and technical advantages of distance protection are considerably large enough because the main advantage of it is that the range of the fault detection in the line is not depends on the changes in the source impedance.The main factors that effects the effectiveness of the traditional distance relaying schemes in single line to ground, double line to ground and specially in simultaneous open conductor fault are the variation in fault resistance, power flow direction as well as magnitude. In this thesis, the work is presented that will discuss about the aforementioned problems of conventional distance relaying methods in doubly fed transmission system. An accurate digital distance relaying scheme integrated with artificial neural network impedance estimator is developed using the conventional method impedance after removal of the error impedance from it using modified scheme. The modified scheme is immune to the variation in fault location for under reach and overreach problem caused by sequence current components. A series of test conducted on a800kV,400km transmission line for single phase to ground faults as well as simultaneous open conductor fault in PSCAD/EMTP and Matlab/Simulink. Finally comparison has been done with the conventional methods in order to check the accuracy and robustness of the proposed scheme which is found to be97%.

Background: Diabetes mellitus (DM) is a syndrome of chronically elevated glucose level in the blood either due to insulin resistance, insulin deficiency or both. In addition, it may occur due to defective metabolism of carbohydrates, fats and proteins. There are 3 main types of DM: Type 2 DM is more prevalent in adults and is typically due to relative insulin deficiency, deficiency of insulin in children leads to DM type 1;and lastly, gestational diabetes occurs during pregnancy resulting from an imbalance of placental hormones. Introduction: Insulin, Biguanides and Sulfonylureas are some of the drug classes used to treat DM. However, their use is complicated by numerous side effects, such as;hypoglycemia & weight gain from insulin and sulfonylureas;lactic acidosis, vitamin B12 deficiency and gastrointestinal upset with metformin. Route of administration and cost are also important factors to consider when prescribing. It is for this reason the quest for newer, safer and easier to administer drugs is ongoing. Methodology: Used all the articles available on anti Diabetic drugs on web especially in British Medical Journal, Elsevier, Pubmed, Google scholar and Wikipedia etc. Got a final review article to compare the older and newer anti Diabetic drugs. Results and Conclusion: Insulin is good for controlling acute hyperglycemic states in DM but it causes acute hypoglycemia and lipodystrophy. Metformin is good hypoglycemic and easily available but causes hypoglycemia, metallic taste, Lactic acidosis and B12 deficiency. Sulfonylureas are good hypoglycemic but causes severe hypoglycemia acutely and weight gain so contraindicated for obese or hypertensive patients. While newer antidiabetics such as GLP 1 agonists increases insulin secretions has very low risk of hypoglycemia, causes weight loss as compared to insulin and decreases risk of cardiovascular side effects but still can’t be used in renally impair
