Development of robust sensor packages for autonomous underwater vehicles

New generations of robots are designed to support humans with a variety of partially or fully automated services. Such flexible and mobile service robots cooperate with humans or even act completely independent. To achieve this, it is necessary to significantly improve their capabilities in terms of environment perception, data processing and movement. At the same time, they must meet the highest standards of reliability and safety. Innovative electronics enable the necessary improvements and thus appropriate robot behavior. The aim of the Bionic RoboSkin project is to enhance the possibilities of a robot platform that is capable of autonomously navigating its respective environment by means of a flexible bionic sensor skin. The sensor platform is an autonomous underwater vehicle [AUV] that is based on the bionic principles of a Manta Ray [1, 2, 3]. The newly developed sensor skin consists of a textile composite as a carrier for sensor elements and provides moisture-resistant electrical connections for energy supply and communication. The integrated sensor modules enable both the detection of touch and approach and the exploration of the environment. The functionality of the sensor skin is targeting two service robotics applications: autonomous surveying of underwater structures (e.g. inspection of pipelines) and semi-autonomous geo-exploration in difficult-to-access areas (e.g. monitoring in tunnel construction). As a result, the paper presents the concept of a modular packaging platform for the use in a harsh marine environment. The technologies used for the miniaturization of the sensor module by PCB embedding and for outer housing development will be discussed in detail and a strong focus is put on packaging material properties in sub-marine conditions.

Tracking Active Glucose-Galactose [TAGG] dynamics in human sweat

Metabolic syndrome conditions, diabetes, prediabetes, and non-alcoholic fatty liver disease (NAFLD) can be observed by monitoring the metabolic biomarkers glucose and galactose. These biomarkers modulate dynamically within human physiology, mainly based on nutritional intake. Traditionally, these biomarkers are measured in blood, which does not lend itself to dynamic monitoring. TAGG is a sweat-based electrochemical platform developed for continuous tracking. This work is the first demonstration of a point-of-care, non-invasive design to detect the dynamic interplay between two biomarkers, glucose and galactose, in human sweat. The TAGG platform detection range for both glucose and galactose is 0.05–32 mg/dL and 0.05 mg/dL limit of detection. Sweat samples were collected from four human subjects. The glucose and galactose data strongly correlated (r = 0.9864 and r = 0.9641) with ELISA standard reference method. By monitoring the dynamics of these metabolic biomarkers, we can gain greater insight into the complex interactions between nutrition and metabolic syndrome. This work demonstrates proof of concept of the non-invasive TAGG detection platform for tracking glucose and galactose dynamics in the low, high, and normal physiological ranges in human sweat.

An Inverse Kinematics Approach for the Analysis and Active Control of a Four-UPR Motion-Compensated Platform for UAV–ASV Cooperation

In the present day, unmanned aerial vehicle (UAV) technology is being used for a multitude of inspection operations, including those in offshore structures such as wind-farms. Due to the distance of these structures to the coast, drones need to be carried to these structures via ship. To achieve a completely autonomous operation, the UAV can greatly benefit from an autonomous surface vehicle (ASV) to transport the UAV to the operation location and coordinate a successful landing between the two. This work presents the concept of a four-link parallel platform to perform wave-motion synchronization to facilitate UAV landings. The parallel platform consists of two base floaters connected with rigid rods, linked by linear actuators to a top mobile platform for the landing of a UAV. Using an inverse kinematics approach, a study of the position of the cylinders for greater range of motion and a workspace analysis is achieved. The platform makes use of a feedback controller to reduce the total motion of the landing platform. Using the robotic operating system (ROS) and Gazebo to emulate wave motions and represent the physical model and actuator system, the platform control system was successfully validated.

The peripheral mobility hub as a multi-sided platform? Applying a Fuzzy Delphi to identify promising stakeholder interactions

Planners increasingly propose mobility hubs linking trunk and feeder transport services to achieve service efficiency, liveability, and accessibility gains in peripheral areas. However, trunk-feeder complementarity at these hubs remains uncertain. This paper aims to enhance understanding of the stakeholder interactions at peripheral mobility hubs through the concept of multi-sided platforms. For the Netherlands, we conducted a Fuzzy Delphi study (n = 59) with representatives of public transport companies (trunk), shared mobility providers (feeder), and asset owners (platform) for the reciprocal evaluation of potential strategies to increase ridership. The data show that trunk and feeder service providers are complementary at the hub to a limited extent. However, platform providers can encourage public transport and shared mobility services to develop their services by improving bike access and providing EV-charging infrastructure.

Fuzzy logic control of an artificial neural network-based floating offshore wind turbine model integrated with four oscillating water columns

Renewable energy induced by wind and wave sources is playing an indispensable role in electricity production. The innovative hybrid renewable offshore platform concept, which combines Floating Offshore Wind Turbines (FOWTs) with Oscillating Water Columns (OWCs), has proven to be a promising solution to harvest clean energy. The hybrid platform can increase the total energy absorption, reduce the unwanted dynamic response of the platform, mitigate the load in critical situations, and improve the system's cost efficiency. However, the nonlinear dynamical behavior of the hybrid offshore wind system presents an opportunity for stabilization via challenging control applications. Wind and wave loads lead to stress on the FOWT tower structure, increasing the risk of damage and failure, and raising maintenance costs while lowering its performance and lifespan. Moreover, the dynamics of the tower and the platform are extremely sensitive to wind speed and wave elevation, which causes substantial destabilization in extreme conditions, particularly to the tower top displacement and the platform pitch angle. Therefore, this article focuses on two main novel targets: (i) regressive modeling of the hybrid aero-hydro-servo-elastic-mooring coupled numerical system and (ii) an ad-hoc fuzzy-based control implementation for the stabilization of the platform. In order to analyze the performance of the hybrid FOWT-OWCs, this article first employs computational Machine Learning (ML) techniques, i.e., Artificial Neural Networks (ANNs), to match the behavior of the detailed FOWT-OWCs numerical model. Then, a Fuzzy Logic Control (FLC) is developed and applied to establish a structural controller mitigating the undesired structural vibrations. Both modeling and control schemes are successfully implemented, showing a superior performance compared to the FOWT system without OWCs. Experimental results demonstrate that the proposed ANN-based modeling is a promising alternative to other intricate nonlinear NREL 5 MW FOWT dynamical models. Meanwhile, the proposed FLC improves the platform's dynamic behavior, increasing its stability under a wide range of wind and wave conditions.

An Experimental Platform for Monitoring, Identification, and Control of HVAC Processes*

This paper presents the concept of an intelligent control system platform equipped with advanced functions and integrated into a unique laboratory demonstrator for simulation of heating, ventilation and air-conditioning (HVAC) processes. The resulting experimental platform constitutes a versatile testbed for development and experimental verification of techniques for signal analysis and feedback control. We proposed and implemented functions for detection of unexpected or undesired signal behaviour, process identification, and discrete-time proportional-integral-derivative and two-degrees-of-freedom controller design. Functionality of the proposed advanced supervision server integrated into the laboratory HVAC testbed is demonstrated using preliminary results obtained from practical testing. The entire concept is built on an open-source control system platform, and is essentially applicable not only for smart buildings but also other industrial applications.

Kako strukturna kriza preokreće ekonomsko razmišljanje i poziva na zelenu tranziciju u Srbiji

These days in the economy and society, along with well-known and highly elaborated internal structural imbalances created by economic neoliberalism and exacerbated by fault lines in reactive policies during serial crises, new disruptive forces related to external asymmetric shocks have been unleashed. Due to widening imbalances, the economy fell in a structural crisis (cascading crisis, rolling crisis or a confluence of crises). A high probability of the emergence of apocalyptic consequences warns us that the situation is extremely alarming. The global economy and the planet are in a serious trap of dying slowly but surely. Finding a systemic solution to rising imbalances is the imperative of our time. The so-called "green transition" is a big idea to mitigate the crisis and make a recovery. It is a way to annul the existing structural imbalances and misconceptions of reactive policies, as well as a platform for sustainable economic growth in balance with the limits of nature. This approach is particularly suitable for developing economies that aspire to catch up with the developed world through new industrialization. In this paper, we attempt to concentrate, among dozens of complex issues concerning the transition from an old to a new economic order, on those solutions pertaining to the economic system adjustments in line with the natural limits in a landlocked, small, open, and developing economy such as Serbia. The great majority of economics scholars have agreed upon the root causes of the crisis as well as the key assumptions regarding problem solutions. In defining our proposals, despite different angles, we intend to integrate the most effective elements of a widely accepted but outside-the-box view. No doubt, it is not certain for how long the current crisis will last. Some mitigation activities already exist. Unfortunately, it is not enough. To reverse the regression trend, four questions need to be answered. What is a global priority for action, and what to ignore? What would be a feasible and effective conceptual platform for the crisis mitigation and the subsequent revival and establishment of a sustainable and inclusive economy? How to coordinate transformative activities in the right direction at the local level? How to weight different instruments to finance the transition from a new normal to a better normal, particularly from the perspective of the mission of economic entities and performance measurement system? To answer the previous questions, the economic theory and public policy should first replace the nexus of neoliberal rules, particularly by making well-being a relevant tenet, not only selfinterest. That requires a paradigm change, in both microeconomics and macroeconomics, by adopting a new nexus of economic rules, capable of explaining the behavior of economic agents, sometimes irrational and inconsistent, but always under the impact of natural limits and "universal connectivity" as a dominant free good in the Fourth Industrial Revolution. The above requires the implementation of the circular model of growth and heterodox economic policy platform. To make the transition to a new system efficient, funding of this endeavor should be of paramount interest. Following the previous line of reasoning, the material is organized in six parts, besides Introduction and Conclusion. The Part 1 is dedicated to the necessity for a fully radical change to mitigate the structural crisis and to set up a new conceptual platform for sustainable and inclusive growth. The Part 2 is focused on the fault lines of the neoliberal economic policy platform, confirming that this platform cannot provide the conceptual base for economic policies during the system change. The Part 3 proposes the green transition as a solution to the aforementioned problems. To invigorate a greener economy, the Part 4 is suggesting the new ways of financing as a smart enough pivot. The Part 5 discusses the transition toward a greener economy as a challenging response to the current economic situation in Serbia. The Part 6 is focused on the necessity for the accreditation of the green transition program for Serbia.

STATE FINANCIAL INCLUSION AS A DRIVER OF MODERNIZATION OF THE PENSION SYSTEM OF UKRAINE

The article considers the policy of state financial inclusion as a driver of modernization of the pension system of Ukraine. A systematic approach to the regulation of state financial inclusion policy and its indicators has been developed, which provides the optimal model for financing pension benefits and social needs of the working age population, taking into account the modernized hierarchy of the pension system and its efficiency in allocating budget resources. It is substantiated that financial inclusion in the system analysis of the state pension system is a platform of the general theory of systems, includes a number of interconnected components of the open financial system from the standpoint of allocation of budgetary resources to social needs. It is proved that the systemic approaches to the use of the methodological paradigm of financial inclusion in the pension system focuses on various aspects of the budget financing process and reflects the conceptual platform for the development of pensions. Models of pension systems and methods of the World Bank according to the levels of pension provision are presented. The directions of financial inclusion in the state pension system in the context of “state – business – society” and the scheme of optimization of state financing of social programs of the pension system are given. The size of pensioners by types and size of pensions in the regions of Ukraine, the coefficient of replacement of lost income in Europe is analyzed. The ratio of the own revenues of the Pension Fund of Ukraine is determined, taking into account the part of the paid single contribution to the obligatory state social insurance, divided into the obligatory state pension insurance to GDP. The total current pension expenditures from GDP in European countries are estimated. The scheme of actuarial calculations of pension provision in the state financial inclusion of the pension system for short-, medium- and long-term periods is proposed.

Nanoclusters with specific DNA overhangs: modifying configurability, engineering contrary logic pairs and the parity generator/checker for error detection.

The most promising alternative for next-generation molecular computers is biocomputing, which uses DNAs as its primary building blocks to perform a Boolean operation. DNA nanoclusters (NCs) have emerged as promising candidates for biosensing applications due to their unique self-assembly properties and programmability. It has been demonstrated that adding DNA overhangs to DNA NCs improves their adaptability in identifying specific biomolecular interactions. A recent proposal in DNA computing is the concept of "contrary logic pairs (CLPs)" executed by employing a DNA hybrid architecture as a universal platform. We have designed thymine overhang-modified DNA-templated NCs (T-Au/Ag NCs). These NCs serve as a chemosensing ensemble platform, where the presence of HgII ions mediates the formation of M-Au/Ag NCs. The resulting NCs exhibit the capability to drive elementary CLPs (YES, NOT, OR, NOR, INH and IMP) as well as complex logic operations (XOR and XNOR). Additionally, they can be utilized for advanced non-arithmetic DNA logic devices like a parity generator (pG) and a parity checker (pC) for "error detection". Bit errors are an unavoidable and common occurrence during any computing. A cascade of XOR operations was used to evaluate these errors by introducing the pG and pC at the transmitting (TX) and receiving (RX) ends in binary transmission, respectively, which has devastating implications for reliable logic circuits, especially in advanced logic computation. Moreover, an even/odd natural number from 0 to 9 distinguishable pC was designed based on a dual-source responsive computing platform. This work offers inspiring avenues for a cost-effective strategy to construct highly-intelligent DNA computing devices by enhancing the multi-input responsive single DNA platform concept.

Refocusing cancer supportive care: a framework for integrated cancer care

ObjectiveCancer supportive care comprises an integrative field of multidisciplinary services necessary for people affected by cancer to manage the impact of their disease and treatment and achieve optimal health outcomes. The concept of supportive care, largely driven by Margaret Fitch’s seminal supportive care framework, was developed with the intent to provide health service planners with a conceptual platform to plan and deliver services. However, over time, this concept has been eroded, impacting implementation and practice of supportive care. This study therefore aimed to examine expert contemporary views of supportive care with the view to refocusing the definition and conceptual framework of cancer supportive care to enhance relevance to present-day cancer care.MethodsA two-round online modified reactive Delphi survey was employed to achieve consensus regarding terminology to develop a contemporary conceptual framework. A listing of relevant cancer supportive care terms identified through a scoping review were presented for assessment by experts. Terms that achieved ≥ 75% expert agreement as ‘necessary’ were then assessed using Theory of Change (ToC) to develop consensus statements and a conceptual framework.ResultsA total of 55 experts in cancer control with experience in developing, advising on, delivering, or receiving supportive care in cancer took part in the Delphi surveys. Expert consensus assessed current terminology via Delphi round 1, with 124 terms deemed relevant and ‘necessary’ per pre-specified criteria. ToC was applied to consensus terms to develop three key statements of definition, and a comprehensive conceptual framework, which were presented for expert consensus review in Delphi round 2.ConclusionFinalised definitions and conceptual framework are strongly aligned with relevant international policy and advocacy documents, and strengthen focus on early identification, timely intervention, multidisciplinary collaboration, and end-to-end, cross-sector, cancer supportive care.

Development and Characterisation of a Whole Hybrid Sol-Gel Optofluidic Platform for Biosensing Applications.

This work outlines, for the first time, the fabrication of a whole hybrid sol-gel optofluidic platform by integrating a microfluidic biosensor platform with optical waveguides employing a standard photolithography process. To demonstrate the suitability of this new hybrid sol-gel optofluidic platform, optical and bio-sensing proof-of-concepts are proposed. A photoreactive hybrid sol-gel material composed of a photopolymerisable organically modified silicon alkoxide and a transition metal complex was prepared and used as the fabrication material for the entire optofluidic platform, including the optical waveguides, the sensing areas, and the microfluidic device. The most suitable sol-gel materials chosen for the fabrication of the cladding and core of the waveguides showed a RIC of 3.5 × 10-3 and gave thicknesses between 5.5 and 7 μm. The material was optimised to simultaneously meet the photoreactive properties required for the photolithography fabrication process and the optical properties needed for the effective optical operability of the microstructured waveguides at 532 and 633 nm with an integrated microfluidic device. The optical proof-of-concept was performed using a fluorescent dye (Atto 633) and recording its optical responses while irradiated with a suitable optical excitation. The biosensing capability of the platform was assessed using a polyclonal primary IgG mouse antibody and a fluorescent labelled secondary IgG anti-mouse antibody. A limit of detection (LOD) of 50 ug/mL was achieved. A correlation between the concentration of the dye and the emission fluorescence was evidenced, thus clearly demonstrating the feasibility of the proposed hybrid sol-gel optofluidic platform concept. The successful integration and operability of optical and microfluidic components in the same optofluidic platform is a novel concept, particularly where the sol-gel fabrication material is concerned.
