In the era of the fourth industrial revolution the enterprise resource planning system (ERP) becomes a foundation for interconnection between logistics systems, production facilities, smart machines, IoT-enabled devices and other enterprise data sources. The paper proposes an approach to extend the ERP integrated analytical tools capabilities by processing ERP data in a multi-tenant GPU-enabled high-performance computing (HPC) environment. Corporate analytic features in conjunction with GPU in-memory processing of big structured and unstructured data increase the performance and analysis effectiveness for enterprise machine learning (ML) tasks. The approach proposes sharing the data in GPU memory using open analytic platform along with existed ERP analytical capabilities on example of SAP S/4Hana. Considered solution accelerates data scientists work with ERP data sets and could be used for faster quality AI model creation and easier data interaction in unspecific for ERP visualization way like immersive learning with virtual or augmented reality (VR/AR). © 2020 IEEE.

Blockchain, which is a new technology of distributed data storage in the form of a chain of blocks, has become one of the most popular topics in the field of information technology for today. Although the term 'blockchain' is often associated with operations in cryptocurrencies (Bitcoin, for example), its application is not limited to this area. The algorithm for automatic confirmation of transactions has already been successfully applied in accounting, postal services, and smart devices. Additionally, people can participate in the confirmation of transactions. This article considers the possibility of using the technology in creating distributed networks of industrial equipment, i.e. creation of a backbone network for cyber-physical production systems. The proposed approach is detailed and discussed with the support of relevant use cases. A number of architectures of support networks based on blockchain technology are proposed, the positive and negative aspects of this approach are considered. © 2018 IEEE.

This paper discusses the topic of synchronizing the reading in writing in an application to real-time TDOA estimation. The paper gives a brief lay down on the classic TDOA estimation algorithm and specifically addresses the peculiarities of its implementation in a real-time environment. There are two main factors that should be considered in the stage of design: the processing time is dependent on the settings and some random factors affect processing time in an unpredictable way. The buffer can be introduced to deal with these factors. However, this solution requires a clear and efficient algorithm of synchronization of reading and writing data. In this paper, we propose a simple and small set of variables that is sufficient to synchronize processes to implement real-time TDOA estimation. The solution supports the various overlap coefficients and time windows that exceed the actual size of the input buffer. The proposed solution is installed on the Raspberry Pi, tested, and proved to be functional. Some practical details of the implementation are also discussed. © 2021 IEEE.

Wind turbines based on the Magnus effect open new prospects in terms of energy generation for areas with low average wind speeds. The main feature of these turbines is rotating cylinders which are used to create lift instead of blades. Due to this unconventional design, different parameters of the cylinder, such as mass and moment of inertia, can greatly affect the dynamic characteristics of such energy systems. The goal of this paper was to present an approach to structural optimization of a cylinder flange of the experimental Magnus effect-based wind turbine. The proposed approach, presented as an algorithm, allows us to determine input data for the preferred structural optimization software and achieve lightweight, low-inertia parts. control simulation has shown that optimized parts ensure a high enough factor of safety while also significantly reducing the moment of inertia. © 2023 IEEE.

The paper presents project and its verification of a prototype integrated circuit containing an analog, programmable finite impulse response (FIR) filter, implemented in CMOS 350 nm technology. The structure of the filter is based on the switched capacitor technique. In circuits of this type, one of main challenges is an efficient implementation of filter coefficients, which result from several factors described in this work. When implementing such filters as programmable circuits, the values of their coefficients have to be limited to a selected range, i.e. a given resolution in bits. In the implemented prototype filter, the filter coefficients are represented by 6 bits in sign-magnitude notation, so they can take 63 different values only. In such filters, it is not possible to directly implement any frequency response of the filter. Each time, it is necessary to properly round the theoretical values of the coefficients so that they fit into the available range of discrete values resulting from the implementation. The authors of the work designed an algorithm that allows such matching. The paper also presents results of measurements of the prototype chip. © 2023 Division of Signal Processing and Electronic systems, Poznan University of Technology (DSPES PUT).

The research presented in this paper focuses on the development of fully automated and autonomous vine suckering, a seasonal viticulture activity required to remove all unwanted shoots from the vine trunks. This requires human workers to do a lot of strenuous work, often using only their hands or tools such as clippers or shears. The suckering is done during the early growing season (usually April-May) to provide more energy, water, and nutrients to the main shoots. Commercially available suckering machines appear to be a large-scale solution. However, their performance varies between 10% and 85% and their purely mechanical nature can easily cause damage to the vines. In this paper, we present a concept for autonomous suckering using a mobile robot equipped with a special suckering tool driven by a torque-controlled DC motor that protects the vine from damage. The proposed suckering system was designed, analysed and experimentally validated in a real vineyard. The results showed that the system was able to remove about two thirds of the unwanted shoots, reaching a suckering rate of more than 86 vines per hour. © 2022 IEEE.

In this paper, a deep learning based object detection model is developed for robotic applications in structured agricultural cultivation of sweet peppers (Capsicum annuum). We propose a realistic simulation based method for procedural generation of a labeled sweet pepper dataset. Realistic 3D models of fruit, leaves, and other relevant plant body parts are generated through photogrammetry, enabling generation of a large and relevant dataset. The dataset is labeled for both object detection and semantic segmentation by scene rendering in multiple layers and using artificial depth information. Smart augmentation techniques are deployed in procedural generation, as well as label filtering techniques for more realistic dataset labels. A MobileNet-SSD based deep learning model is trained through transfer learning on the generated dataset. The trained model is tested both in simulated environment, as well as on a relevant real-world setup. © 2022 IEEE.

Since the dominant induction machines and permanent magnet synchronous machines are well-established in the industry, the reluctance machines require more research work and investigation to substitute the conventional technologies. This paper analyzes the synchronous reluctance machines and permanent magnet-Assisted synchronous reluctance machines in terms of the effect of permanent magnets in the model and the performance characteristic of the machines. The machines are designed and the parameters are measured. The vector diagrams of the machines and the equivalent circuits of the machines are analyzed. A comparison of the machines in terms of power factor, efficiency, and torque of the machines is provided based on the measurements. The study presents a notable improvement in power factor and efficiency in the case of inserting permanent magnets in the synchronous reluctance machine's rotor. © 2020 IEEE.
