the aim of this article is to develop optical aberration correcting methods using adaptive optics for confocal microscopy in imaging systems. In order to compensate the aberrations, a dynamic element, consisting of a deformable mirror, was used. the correction is performed by controlling the surface of the deformable mirror, in order to improve the overall system image resolution. Moreover, the wavefront sensorless system case was considered. By combining the automatic control algorithms withthe physics laws, quite accurate estimations can be obtained, while testing several different scenarios.

Smart grid technology is the future of electricity ordered by computers. this article presents the characteristics of the new technological developments in this area and reveals the fractal nature of this architecture, leading to a holonic structure which presents smart grid as a system bottom-up organized from autonomous entities that are recursively clustered at various aggregation layers. Taking into account the novelty of the subject, this paper should bring new opportunities to explore and develop this domain.

Wireless sensor networks are a cheap and versatile solution for monitoring various environments. the data gathered by these sensors is often used in research projects and science experiments. It is necessary to ensure that a certain level of security and protection is instated for the transmitted data. Current software security methods implemented on wireless sensor networks do not necessarily take into consideration the lifetime and autonomy of the nodes. this paper presents an analysis of a software AES implementation on SparrowE wireless sensor nodes and shows a comparison between the viability of such a method with regard to hardware AES.

the principles of the fractal geometry are applied for simulated and real images of the vessels. the final goal is to prove the utility of these techniques to diagnose some important vascular diseases such as the stenosis and the arterio-venous malformations from the X-ray angiography. the computation of the fractal dimension based on Box-Counting method is worthy from the point of view of differentiation the healthy tissues from the diseases ones and needs further investigation using the fractal theory.

A particular Mobius transformation mapping a completely general discrete-time algebraic dynamical system into a standard (proper) continuous-time one is introduced and studied. the freedom in choosing ab ante the exclusion point (in which the transformation is not defined) different from any point of interest makes this transformation a powerful universal tool for solving virtually any optimal/robust control problem for this class of systems by an elegant, yet simple reduction to known results. We show the effectiveness of our approach on two keystone problems: the normalized coprime factorization and the parametrization of all stabilizing controllers.

this paper describes a Weather Android application which shows the evolution of the meteorological parameters for a chosen location or along a route. this application helps the user to have a safety trip by avoiding dangerous climate changes. To increase the exactness of the prediction, the information is based on a high-resolution, short-term numerical weather model. In order to assess the quality of a numerical forecast, we compare it withthe corresponding observation or a good estimate of the true outcome.

In the early days of the Open Source Robotics Foundation, a lesser-known project aimed to design an “app-able robot”, leading to the creation of the “Capabilities” package for the Robot Operating System (ROS). Over a decade later, formulating robot capabilities remains a significant technical hurdle in bringing robots from the lab into everyday life. this paper introduces Capabilities2, a successor to the original Capabilities package, now reimagined for ROS2. Capabilities2 enhances the original design by enabling advancements in skill-based control techniques and offering a more efficient, extensible framework for defining and utilising robot capabilities. We delve into its application in new real-world scenarios, with a particular focus on human-robot interactions and the deployment of collaborative mobile robots in human-centric environments. Capabilities2 addresses challenges in implementing intuitive, collaborative robots by introducing an abstracted database handler, an object-relational mapping for capability models, and a plugin architecture for capability execution. these features support dynamic capability representation, runtime adaptability, and integration with modern AI techniques for skill-based task planning. By providing a standardised yet flexible framework, Capabilities2 reduces the integration effort required to develop top-level controls for real-world scenarios, facilitating rapid development and deployment. Our contributions include the reimplementation of the Capabilities package in ROS2, enhancements to support contemporary robotic applications, and demonstrations of new use cases enabled by Capabilities2. We believe that Capabilities2 significantly advances the field of robotics by equipping developers with tools to create more capable, adaptable, and interactive robots. Capabilities2 is available at https://***/CollaborativeRoboticsLab/capabilities2

this paper presents some results of a research work that aims to use Brain - computer Interfaces to facilitate rehabilitation training of a patient who has lost motor functions. Brain computer Interface would be connected to the computercontrolled robotic glove based on signals acquired through this interface. the subject may imagine movements that will be transmitted to the hardware components of the robotic glove. the paper is focused on the study of classification algorithms that can be optimal candidates for signals classification obtained in order to identify different types of movements. Two types of neural networks-based classifiers are used and tested in order to compare the results: Multi-Layer Perceptron (MLP) and Radial Basis Function (RBF).

One of the inconveniences of recovering after a stoke for patients is that they have to go either to a hospital or to a private clinic in order to follow a rehabilitation exercise program for movement control recovery and nerve reactivation. this paper presents a proof of concept for a portable robotic glove produced by a 3D printer that is controlled by an image processing approach and that is capable to mimic the movements captured by a camera. the developed software uses fuzzy logic to imitate the movements and makes use of open-source code for hand and fingertip detection and tracking based on computer vision.
