The world is currently experiencing population explosion, and it has been forecast that the population would reach nine billion by the year 2050. This rapid population growth is accompanied with new challenges, including high demand for food supply, which may lead to food crises. Contemporary agricultural methods and resources cannot meet the forecast food demand. Precision agriculture is one of the best ways to meet this demand, and using agricultural robots is an important aspect of it. Many researchers have been conducting studies on the application of robots in agricultural tasks such as farm clearance, seeding, seedling, spraying, fertilization, and harvesting. This paper presents a comprehensive review on path planning techniques for agricultural robots. it focuses on different types of agricultural robots and path plans in use. It also provides taxonomy of agricultural robot path plans, metadata analysis, and deep insights into the recent developments in the research area, while pointing out the challenges being faced and possible future solutions. This article may serve as a guide to early career researchers with interest in agricultural robots to easily understand the current developments and the future research focus in this field. © 2022 IEEE.

In the last two decades, Chaos theory has received a great deal of attention from the cryptographic community. This paper presents two ideas. First idea is using chaotic functions to overcome the weaknesses of the classical Hill cipher. The second idea is proposing a new encoder-decoder architecture, called ChaoEncoDeco, for securing JPEG images. An extra stage of encryption is embedded within the traditional JPEG codec to improve security level of such system. This security stage uses one of the chaotic functions called Logistic Map. This map is used to enhance the Hill cipher and achieve more secure encryption key. The properties of both chaotic system and of the Hill cipher encryption key are all utilized to obtain ultimate secure systems. The proposed encryption algorithm is crypto-analyzed and compared to the standard Hill cipher algorithm. Complete evaluation for the proposed architecture is also performed which indicates the effectiveness of the proposed system. © 2011 IEEE.

Industry 4.0 involves the integration of digital technologies, such as IoT, Big Data, and AI, into manufacturing and industrial processes to increase efficiency and productivity. As these technologies become more interconnected and interdependent, Industry 4.0 systems become more complex, which brings the difficulty of identifying and stopping anomalies that may cause disturbances in the manufacturing process. This paper aims to propose a diffusion-based model for real-Time anomaly prediction in Industry 4.0 processes. Using a neuro-symbolic approach, we integrate industrial ontologies in the model, thereby adding formal knowledge on smart manufacturing. Finally, we propose a simple yet effective way of distilling diffusion models through Random Fourier Features for deployment on an embedded system for direct integration into the manufacturing process. To the best of our knowledge, this approach has never been explored before. copy;2023 IEEE. © 2023 IEEE computer Society. All rights reserved.

Intelligent assumption retrieval from process models by model-based reasoning 1

Process models can be seen as structured knowledge base elements with syntax and semantics dictated by the underlying physical and chemical laws. The effect of model simplification assumptions is then determined by forward reasoning in order to take into account all of their implications. A bidirectional reasoning method for the retrieval of modelling assumptions from two related process models is proposed. An intelligent model editor is constructed to perform and test the model-based reasoning methods related to the assumption retrieval. © Springer-Verlag Berlin Heidelberg 2001.

A processes composed of sequences of local cyclic The theoretical prediction of the behavioral properties of periodic structures is less difficult than in the case of nonperiodic ones. That is because all the information needed to describe the entire structure is given by the elementary substructure itself and by the manner it repeats in the whole periodic structure. So, only a small portion of the structure (which includes the repeating substructure) needs to be considered to obtain the properties of the whole periodic structure. In that context, the contribution provides the discussion of some system periodicity issues, and is aimed at modeling and evaluation of relationships linking the system structure features with required system's functioning. © 2013 IEEE.

The paper indicates an analytic computing relation for the solution to Riccati differential matrix equation and -based on that- it establishes the weight matrices influence on the solution of the equation and on the LQ-Problem’s criterion minimum value either. It indicates also an efficient way for the optimal controller implementation.

This paper proposes an approach of dynamic fuzzy modeling applied to friction compensation to enhance the performance of a servodrive system in tracking a trajectory. The fuzzy observer is derived from the dynamic nature of friction, and is used to suppress friction-induced errors. The linearity of the local models simplifies the design of the observer and its estimation capabilities are improved with the addition of a nonlinear compensating gain. Simulation results demonstrate the effectiveness of this observer-based control strategy. ©2007 IEEE.

This paper proposes an asymmetrical pulse width modulation (APWM) with frequency tracking control of full bridge series resonant inverter for induction heating application. In this method, APWM is used as power regulation, and phased locked loop (PLL) is used to attain zero-voltage-switching (ZVS) over a wide load range. The complete closed loop control model is obtained using small signal analysis. The validity of the proposed control is verified by simulation results.
