Online condition monitoring of machineries, equipment and rotating components in modem manufacturing is used to find the working condition, identify the fault and determine the remaining useful life of a component. The focused benefit of condition monitoring is to increase the reliability, functionality, machining efficiency and surface property of the component and to reduce the downtime and power consumption. Monitoring of the system can be done through vibration, temperature and sound. Vibration analysis on rotating component will give an efficient output for fault diagnosis. This paper deals with vibration signals;the signals are acquired from rotating spur gear system using an accelerometer and the statistical features are extracted for classifications by mathematical software. Distinguished vibration signals as good and faulty are used for fault diagnosis of spur gear with the help of machinelearning approach for online condition monitoring. The predominant features were given as input to the classifier J48 algorithm. Accuracy of classification was observed as of 90.18 %. Hence J48 algorithm can be practically utilized to monitor the condition of spur gear system. (C) 2019 Elsevier Ltd. All rights reserved.

In this paper, a secure machinelearning based indoor localization algorithm is proposed, when the received signal strength (RSS) measurement fingerprint based training data set is given by chunk-by-chunk and contains the attacked training data samples. In the off-line phase, the hierarchical clustering approach is proposed to distinguish the attacked training data and the attacked-free training data, firstly. By the above data pre-processing, the attacked RSS measurements is found and can be deleted. Then, the online sequential extreme learningmachine (OS-ELM) algorithm is used to training the attacked-free data in turn. In on-line phase, according to the obtained RSS measurements, the obtained regression models are straightly used for final position estimation. Field tests are carried out to show the advantage of the proposed secure localization algorithm over traditional OS-ELM based approach.

A wafer is a thin slice or substrate of semiconductors used for the fabrication of microelectronics devices. Thus, a large scale of precision is needed to make the microdevices work properly and to meet the requirements. Wafer test is an important step in wafer manufacturing to validate the activity of the microdevices and produces pictures of each wafer based on the electrical measurement of each of the devices on the wafer. Wafer shows different patterns while testing based on the requirement gap present on some of the devices on the wafer. To detect this error pattern manually is almost an impossible and time-consuming act. Therefore, we are presenting a wafer map pattern recognition system based on some ensemble approaches. Three (3) different ensemble including bagging, boosting, and voting approaches are implemented. Bagging performs relatively better than the others.

In recent years, due to advancement in modern technology and social communication, advertising new job posts has become very common issue in the present world. So, fake job posting prediction task is going to be a great concern for all. Like many other classification tasks, fake job posing prediction leaves a lot of challenges to face. This paper proposed to use different data mining techniques and classification algorithm like KNN, decision tree, support vector machine, naïve bayes classifier, random forest classifier, multilayer perceptron and deep neural network to predict a job post if it is real or fraudulent. We have experimented on Employment Scam Aegean Dataset (EMSCAD) containing 18000 samples. Deep neural network as a classifier, performs great for this classification task. We have used three dense layers for this deep neural network classifier. The trained classifier shows approximately 98% classification accuracy (DNN) to predict a fraudulent job post.
