The present work aims at the evaluation of the effectiveness of different machine learning algorithms on a variety of clinical data, derived from small, medium, and large publicly available databases. To this end, several algorithms were tested, and their performance, both in terms of accuracy and time required for the training and testing phases, are here reported. Sometimes a data preprocessing phase was also deemed necessary to improve the performance of the machine learning procedures, in order to reduce the problem size. In such cases a detailed analysis of the compression strategy and results is also presented. 2018 The Authors. Published by Elsevier Ltd.

It is very important to diagnose the mechanical failure of the motor in the industry. The conventional method is difficult to include both the various motors and the driving environment. In order to solve these problems, researches have been actively conducted to apply deep learning to fault diagnosis. Many studies focus on vibration data. Noise data can be collected easily and inexpensively compared to vibration data. In this paper, vibration data and performance were compared using noise data as training data from the diagnosis of motor failure. In the first experiment, vibration and noise data were collected in the same experimental environment. The collected data were compared through the same algorithm. In the second experiment, we compared the performance of the three deep learning models. As a result, both the noise and vibration data showed high accuracy and sufficient fault diagnosis was possible considering the vulnerability of the disturbance.

Disruptions within engineering toolchains as well as scattered system specifications still impede the integration of phase-spanning system design approaches for production machines. Aside of the necessary high efforts to gather the essential requirements for the implementation of a component or process, this also inhibits documenting the reasons for a specific choice of a particular machine concept. Though to achieve reasonable system designs, it is necessary to link and track requirements with the implementing machine structures - consistently and synchronized across all design phases. Therefore, this article presents an approach for a requirements-based toolchain, which enables the data-consistent use of requirements in the system design phase of production machines. Based on the specification language IML (Interdisciplinary Modeling Language) and its central interdisciplinary system model, intuitive operation principles shall support the definition of component-specific requirements sets while round-trip strategies realize synchronized requirement profiles and histories.

Computer Supported Cooperative Work (CSCW) in design is an essential facilitator for the development and implementation of smart cities, where modern cooperative transportation and integrated mobility are highly demanded. Owing to greater availability of different data sources, data fusion problem in intelligent transportation systems (ITS) has been very challenging, where machine learning modelling and approaches are promising to offer an important yet comprehensive solution. In this paper, we provide an overview of the recent advances in data fusion for Mobility as a Service (MaaS), including the basics of data fusion theory and the related machine learning methods. We also highlight the opportunities and challenges on MaaS, and discuss potential future directions of research on the integrated mobility modelling.

This paper proposes the use of a Case-Based Reasoning (CBR) system for the control and the supervision of a real wastewater treatment plant (WWTP). A WWTP is a critical system which aims to ensure the quality of the water discharged to the receiving bodies, stablished by applicable regulations. At the current stage the proposed methodology has been tested off-line on a real system for the control of the aeration process in the biological treatment of a WWTP within the ambit of Consorci Besos Tordera (CBT), a local water administration in the area of Barcelona. For this purpose, data mining methods are considered to extract the available knowledge from historical data to find a useful case base to be able to generate set-points for the local controllers in the WWTP. The results presented in this work are evaluated taking into account the performance of the CBR method e.g. case base size, CBR cycle time or number of cases resolved satisfactorily (forthcoming steps will include on-line tests). For this purpose, some Key Performance Indicators (KPI) are designed together with the plant manager and process experts, in order to monitor key parameters of the WWTP which are representative of the performance of the control and supervision system. Hence, these KPI are related with water quality regulations -e.g. ammonia concentration in the WWTP effluent- and the economic cost efficiency -e.g. electrical consumption of the installation. In order to evaluate the results, different flat-based memory organizations (i.e. cases are stored sequentially in a list) for the case base are considered. First, a unique case base is used. At the current stage and for the results shown in this work, this case base is divided in multiple libraries depending on a case classification. Finally, the combination of this approach with Rule-Based Reasoning (RBR) methods is proposed for the next stages of the work.

An important source of transformer noise is magnetostrictive vibration of the magnetic core. This paper outlines some important effects of vibration on aging due to the deterioration of insulation by on-line measurement. The acceleration in the XYZ axis is telling the model of the vibrational force. A large amount of data can be collected as a database for maintenance decisions and take care of electrical insulation. Finally, collect data into the data management process using data mining. Storage data is much smaller approximately 1.17% as compared to all data.
