Abstract A multi-objective improved genetic algorithm is constructed to solve
the train operation simulation model of urban rail train and find the optimal
operation curve. In the train control system, the conversion point of operating
mode is the basic of gene encoding and the chromosome composed of multiple
genes represents a control scheme, and the initial population can be formed by
the way. The fitness function can be designed by the design requirements of the
train control stop error, time error and energy consumption. the effectiveness of
new individual can be ensured by checking the validity of the original individual

Abstract The miniaturization and endurance of wearable devices have been the
research direction for a long time. With the development of nanotechnology and
the emergence of microelectronics products, people have explored many new
strategies that may be applied to wearable devices. In this overview, we will
summarize the recent research of wearable devices in these two directions, and
summarize some available related technologies. More >

Abstract Human beings and their activities are now connected through Internet
of Things (IoT) with the evolution of wireless communication technologies. IoT
is becoming popular and its usage is immensely increasing among various
sectors. In this research paper, a comprehensive review has been conducted by
considering recent and important literature review on IoT applications being
operated in three major sectors. The three sectors studied are health, sports and
transportation and logistics. Paper explored that with the help of IoT techniques,
different miniature sized devices are invented which can record various
parameters of human body, wearables devices have been invented which are… More >

Abstract Increased smart devices in various industries are creating numerous
sensors in each of the equipment prompting the need for methods and models for
sensor data. Current research proposes a systematic approach to analyze the data
generated from sensors attached to industrial equipment. The methodology
involves data cleaning, preprocessing, basics statistics, outlier, and anomaly
detection. Present study presents the prediction of RUL by using various
Machine Learning models like Regression, Polynomial Regression, Random
Forest, Decision Tree, XG Boost. Hyper Parameter Optimization is performed to
find the optimal parameters for each variable. In each of the model for RUL
prediction RMSE, MAE… More >
