this paper introduces a new approach to mine business processes. We define bidirectional tree languages together withtheir finite models and show how they represent business processes. then we propose an evolutionary heuristic based on skeletal algorithms to learn bidirectional tree automata. We show how the heuristic can be used in process mining.

In this paper, Robotic application using a microcontroller ATmega2560 based kit mounted with low cost IR sensors for mapping and localization of unknown area is accurately carried out by using Kalman Filtering to determine or measure different parameters. this paper highlights the comparision between the accuracies of output data obtained from IR sensor using Average Technique as well as Kalman Filter. Various cases depending on robot movement in forward and backward direction and wheel rotation in clockwise and anticlockwise direction, are considered in this paper to calculate position encoder resolution. Also probabilistic estimation of actual position of robot is carried out using different techniques i.e Probabiity Density Function (P.D.F) for verifying the uncertainity in its position and found to be very close to actual position. Simultaneous Localization And Mapping (SLAM) is the only way a robot can navigate through an unknown environment withthe use of minimum sensors and get reliable output of the same in identifying an unknown area. Using this method the robot not only create a map more accurate than GPS maps but also localize itself to determine its next position according to the map created more accurately at lower cost. Primarily used for creating a map of an unknown location, this concept can also be used to perform Qualitative Analysis of a given area by equipping the robot with appropriate sensors.

In this work, we propose a control strategy by state convergence applied to bilateral control of a nonlinear teleoperator system with constant delay. the bilateral control of the teleoperator system considers the case when the human operator applies a constant force on the local manipulator and when the interaction of the remote manipulator withthe environment is considered passive. the stability analysis is performed using Lyapunov-Krasovskii functional, it showed that using an control algorithm by state convergence for the case with constant delay, the nonlinear local and remote teleoperation system is asymptotically stable, also speeds converge to zero and position tracking is achieved. this work also presents the implementation of an experimental platform. the mechanical structure of the arm that is located in the remote side has been built and the electric servomechanism has been mounted to controltheir movement.

In order to set up well-structured multitasking robot application programs careful planning is required. Robot programming languages (e.g. Karel, RAPID, Melfa, SimPro, etc.) vary from robot to robot constructor. General planning tools used in software development (e.g. UML, IDEF, etc.) require adequate professional skills and a special way of thinking such that robot programmers to apply and adapt them to the specificity of each robot programming language. Customized and intuitive planning tools of robot applications with regard to each particular programming language seem to be preferred by ordinary robot programmers and operators when facing withthe development of complex robot tasks. this paper introduces such a tool in relation to the RAPID (TM) programming language, specific to ABB robot models. Its effectiveness is revealed in a case study.

automation, and closely related information systems are, naturally innate, and integrated ingredients of all kinds of objects, systems, and social relations of the present day reality. this is the reason why this contribution treats the phenomena and problems of this automated/information society in a historical manner with a wider, structural framework, giving special emphasis to TECIS. the classical international Federation of Automatic control's (IFAC) topic of social effects is continually evolving and is moving towards human-machine cooperation. this means that automation technologies require a more interdisciplinary educated workforce. In addition developing countries need access to the newest technology to efficiently and effectively improve their industries. this contribution benchmarks selected important development trends of the Technical committee 9.5 (TECIS). It outlines the social aspects of automation, cost orientated automation, semi-automated assembly and disassembly (end of life), mechatronics systems and robotics, cooperative robotics, engineering ethics and diversity and inclusion in automation. As well as looking forward to future development trends it also looks backwards at the history of automation in the context of TECIS. Copyright (C) 2021 the Authors.

A great deal of work has been done in recent years on the multi-robot patrolling problem. In such problem a team of robots is engaged to supervise an infrastructure. Commonly, the patrolling tasks are performed withthe objective of visiting a set of points of interest. this problem has been solved in the literature by developing deterministic and centralized solutions, which perform better than decentralized and non-deterministic approaches in almost all cases. However, deterministic methods are not suitable for security purpose due to their predictability. this work provides a new decentralized and non-deterministic approach based on the model of Game theory called Stochastic Fictitious Play (SFP) to perform security tasks at critical facilities. Moreover, a detailed study aims at providing additional insight of this learning model into the multi-robot patrolling context is presented. Finally, the approach developed in this work is analyzed and compared with other methods proposed in the literature by utilizing a patrolling simulator.
