In the paper the problem of Wiener-Hammerstein system (LNL) modelling by exponentially weighted aggregation of models is discussed. The class of systems under consideration admits almost any LNL objects even with infinite memory and virtually arbitrary nonlinear characteristic. Given the set of various possible models of the true system (being e.g. the result of prior identification attempts), the proposed approach yields mixed model that efficiently mimics input-output relationship of the genuine LNL system. Detailed analysis of the approach demonstrates good theoretical properties of the resulting (aggregated) model, whereas numerical simulations illustrate practical aspects of the considered method.

The paper presents a development of a mobile platform for a robot dedicated for remote USG examination. The design process uses a component based approach for system development and platform functions are implemented within the Xenomai-OROCOS-ROS (XOR) software framework. The paper presents how the testbed platform Carol evolved to the new ReMeDi platform prototype and elaborates the new low level controller and changes in mechanical and sensory systems.

In systems that support dynamic allocation of work across human and autonomous agents, mechanisms for the delegation of authority are required. A case study inspired by the Uberlingen mid-air collision is presented demonstrating an instantiation of a delegation assignment and coordination model. The scenario includes multiple delegation assignments issued from two sets of delegating agents to the same set of adopting agents. For one aircraft, two delegation assignments are made: a clearance from an air traffic controller and an opposing resolution from flightdeck traffic collision alerting automation. For the other aircraft, one delegation assignment is made (a resolution from flightdeck traffic collision alerting automation that is coordinated with the other traffic's automation and that makes the effect of the air traffic control clearance hazardous). The example demonstrates how the agents involved in Uberlingen assigned and accepted multiple, coupled delegations and highlights issues arising from available information and the timing of assignments that may interfere with adherence to coordination procedures. This example indicates the need to extend methods for modeling of delegation assignment and coordination in order to inform the design of autonomous agents, associated procedures, and decision support.

Wireless Sensor Networks (WSNs) have been widely considered as a promising solution to support different types of applications on industrial environments. Many of these applications impose strict dependability requirements, since a system failure may result in economic losses, or damage for human life or to the environment. The absence of an effective approach enabling the dependability evaluation of WSNs prevents system designers to forecast these type of scenarios or to optimize decisions regarding the criticality of the devices, network topology, levels of redundancy and network robustness that minimize the occurrence of faults. To bridge the gap between research achievements and industrial development, we present in this paper a framework to support the dependability evaluation of WSNs based on the automated generation of analytical dependability models from high level AADL (Architecture Analysis and Description Language) architecture models. The main objective of this framework is to relieve the end user from a deep knowledge of dependability modeling techniques and evaluation methods, focusing on their knowledge of the behavior and structure of the system.

In paper, forecasting models using Prophet algorithm for occupational diseases incidence rate for Polish coal mining are presented. Prior to this, data is analyzed and approach for building forecasting models in Prophet is described in details. Forecasting models for occupational diseases incidence rate are revealed, respectively for all sectors in Poland, mining industry and finally for coal mining including only pneumoconiosis. Improved forecast accuracy with presented models might provide coal mine enterprises more precise data, supporting safety management in those organizations.

In order to improve and control the accuracy of robot system, Based on the theory of matrix differential expression presented in reference 1 and independent action principle of errors, the models of structural parameters, clearances and the comprehensive shape and position errors of mechanism are established and the error synthesis is obtained in the form of vector sum. Furthermore, the repeatable position accuracy of a 6-DOF serial robotic mechanism has been accomplished by Monte Carlo method,which provides a new method for error analysis of robot mechanism and a reference basis for precision optimization design.

Combined with medical robotic system, mechanical property characterization of the prostate could enhance the diagnosis and localization of prostate cancer. However, despite the importance of localization, complex geometry and boundary conditions of the prostate make localization difficult. This paper proposes a method for localizing abnormality using finite element modeling of the prostate glands. Ex-vivo experiment was performed to resected human prostate tissue for six regions of the prostate using robotic system which was previously designed to induce sweeping palpation. For each region, three dimensional prostate computational models from the CT image segmentation were developed for mechanical property characterization and local property criteria construction. The measured force responses were applied to the prostate model fittings and mechanical property of ex-vivo experiments were estimated. By using comparative study with local property criteria from the prior indentation study, suspicious regions were localized. The results showed that the suspicious regions were discriminated and the sensitivity was 66.7%.
