Chinese Journal of Electronics 2020年第5期29卷 826-832页

The key of swaying tree simulation is to capture the essence of the interaction between wind and tree, which has not received much attention from scholars. In this paper, we present a method for simulating swaying tree based on slicing partition. The tree is divided into multiple "slices", and then jointly moved to simulate the tree swaying in wind. By slicing partition,the motion of any slice is independent of the others concurrently, which provides a parallel spatial topology for real-time calculation. Moreover, based on the fact that the wind will blow to a tree partly rather than the whole, partial swayings of the tree are also simulated. The experimental results show the correctness and effectiveness of our method.

Observer-based controller design for the minimally invasive surgery

引用

Current Directions in Biomedical Engineering 2018年第1期4卷 41-44页

作者： Smolinski, Eike Benkmann, Alexander Drewelow, Wolfgang Jeinsch, Torsten Cappius, Hans-Joachim Westerhoff, Peter Institute of Automation Faculty of Computer Science and Electrical Engineering University of Rostock Rostock Germany World of Medicine GmbH Berlin 10587 Germany

Due to its advantages like minimal trauma and a low risk of infections, the minimally invasive surgery (MIS) has become the standard operation technique for many surgical procedures. During this type of intervention, one of the main tasks from a technical point of view is the control of the pressure in the operation area in order to give the surgeon sufficient space to perform his actions. Because no invasive measurements are available, an extended Kalman filter incorporating the peristaltic behavior of the used medical device was developed to estimate the pressure in the operation area. This contribution focuses on the observer design while a separately designed PI controller using loop shaping was employed for validation. The proposed observer-based control structure was tested with a simulator deploying the principle of physical equivalence. © 2018 Eike Smolinski et al.

The impact of technology affects the educational field in an extraordinary way. The effect of technology must be treated from the educational method itself as well as its horizon in the new paradigm of citizen in this smart environment. This work proposes a revision of the immediate future of education and citizenship, as determined by the exponential impact of technology, based on relevant issues of classic philosophy and specially along the history and didactic program of the Trivium (Grammar, Rhetoric and Logic). The paper analyses firstly the perspective of the transformation of current education towards a smart education. This transition is determined by the development of Artificial Intelligence (AI), and the reflection on the competences of the 21st century, as something intrinsically related to the issues of citizenship as well as smart cities;secondly, we review the strategic and methodological proposals in accordance with this transformation, based on the theory of generative learning and on computational and algorithmic thinking;thirdly, from the point of view of contents, we analyse the importance of digital skills and, as a fundamental element of these, programming skills. Our proposal is to recover and update the contents of the Trivium, as a renewing and revitalizing element of the methodology and contents of education in the 21st century. This proposal is based on the assumption of the epistemological unity of these disciplines and on the integral anthropological vision that supports them. Both ideas acquire special relevance in the current context marked by the impact of technology as a determining element of the medium (smart education), of the methodology (generative learning, computational thinking) and of the contents (digital skills and programming). © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.

Industrial furnaces are often used in siderurgy and metallurgy applications. Most of them are based on burning different fuels or use electrical resistors to bring the temperature to the desired working conditions. This paper aims to show a possible approach of an adaptive controller implementation using neural networks to reduce the gas consumption of industrial furnaces. The neural networks generate the appropriate coefficients, both for the transfer function and the controller, with respect to the variation of the gas flow. © 2024 IEEE.

This paper presents an innovative API to help a trainee-teacher design Formative-Assessment (hereafter FA) Freirean-dialogues in a data-analytics education project. The API is emerged in context of our act to help a trainee-teacher in Germany understand what hinder the Syrian oppressed students/immigrants express freely their thoughts/critiques in group-discussions about how to initialize data-analytics education project for their self-overcoming goals. The paper shows how we interpret Freire's two works 'pedagogy of the oppressed [1] and pedagogy of freedom [2]' and expose our interpretations as API's design-elements and use-value guidelines for trainee teacher's two helping functions;the first is to help him/her coordinate critical reading/analyzing circles for practicing Freirean multi-factor analysis of oppression in context of the Syrian adult oppressed learners. The second is to help him/her design and prepare FA Freirean dialogues to assess formatively (i.e., analyze critically) a limit and oppressive situation of Syrian adult learners. Moreover, it enables him/her to prepare advanced FA Freirean dialogues for analyzing critically the limit and oppressive situation and its Freirean untested feasibilities for self-overcoming. To test the API's two helping functions, test cases are suggested as next steps of this work-in-progress paper. Finally, for reflective-feedback exchange with FIE community we summarize the API's limits and our next steps to improve it. © 2023 IEEE.

The paper proposes a solution for modelling and controlling the operation of a DC/DC boost converter. The converter model is based on a neural network structure. The feedforward fully connected neural networks generate the appropriate model coefficients for the variable duty cycle. An optimal control approach is used for controlling the operation of the converter, and also reject external disturbances and return the system back to the steady-state regime. This approach will also be compared to the work of other authors which chose a Ziegler-Nichols controller. In the end, the paper will show that the chosen adaptive control strategy is also more energy efficient than a conventional control strategy. © 2024 IEEE.

作者： Ezzine, Abderrahim Laaidi, Naouar Zealouk, Ouissam Satori, Hassan Department of Computer Science and Mathematics Faculty of Sciences Dhar Mahraz Sidi Mohamed Ben Abbdallah University Laboratory of Computer Science Signals Automation and Cognition (LISAC)

Building efficient acoustic models for dialects is a major challenge in Automatic Speech Recognition (ASR) systems. In this paper, we investigate the Moroccan Fessi dialect speech recognition system based on phoneme modeling. We employed a combined approach, including the Hidden Markov Model (HMM) and the Gaussian Mixture Model (GMM). Also, the ASR dialect specificity was analysed, including phonemes nature and phonetic inventory. Our results show the best performance was found by using 3 HMM and 4 GMM configurations, achieving an accuracy of 97.33%. Additionally, we observed that the digits containing voiced pharyngeal phonemes, particularly the phoneme /ʕ/, achieved the highest recognition rate, while words containing the phoneme /s/ exhibited multiple substitutions. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2024.

This paper describes the results of benchmarking two blockchain platforms' performance. The authors conducted a performance assessment of various actions including adding, editing, deleting, and selecting the data from a blockchain. The blockchain platforms were run locally, in Ganache for Ethereum and IBM Blockchain Platform for Hyperledger Fabric. Additionally, code optimizations at the smart-contract level resulted in higher test speeds for both cases. The experimental case consisted in storing students' diploma identification numbers, with the practical aim of preventing document forgeries. © 2023 IEEE.
