This paper addresses the problem of basic control loops in wastewater treatment plants. By basic control loops we are referring to the traditional dissolved oxygen and nitrates. In a usual activated sludge process based wastewater treatment plant, these controls are located, respectively, at the aerated and anoxic sections. They are the basic controls more sophisticated control solutions can be based upon. Therefore it is important that these loops perform in an efficient way. The problem is addressed here within the framework provided by the Benchmark Simulation Model Number 1 (BSMI) and by the use of an event-based solution. As far as to the knowledge of the authors, no solution based on this kind of controllers has been proposed already in the literature. The controllers are taken as of similar complexity as the ones provided as default control strategy in the BSMI, therefor being the main difference, the possibilities provided by the event-based implementation. It will be verified that the solution can slightly improve the performance of the already exiting controllers both at loop level as well as at plant operation level.

Shielded through-silicon vias (S-TSV) filled with multi-walled carbon nanotubes (MWCNT) in the via and the shielded layer, and benzocyclobutene or silicon in the insulation layer is presented in this paper. Then, the equivalent transmission line models of the two S-TSVs are established. Based on the model, the forward transmission coefficient and attenuation constant are calculated and the impact of quantum capacitance C q of MWCNT on the transmission performance of S-TSVs is analyzed. The results indicate that the performance of S-TSVs with Si insulation layer in 0-100 GHz can be significantly improved by C q . Also, the performance of S-TSV filled with BCB above 40 GHz can be improved. In addition, the temperature effect of silicon can be balanced by C q . As a result, the heat stability of S-TSV with silicon insulation layer is improved.

In shape optimization, design improvements significantly depend on the dimension and variability of the design space. High dimensional and variability spaces are more difficult to explore, but also usually allow for more significant improvements. The assessment and breakdown of design-space dimensionality and variability are therefore key elements to shape optimization. A linear method based on the principal component analysis has been developed in earlier research to build a reduced-dimensionality design-space, resolving the 95% of the original geometric variance. The paper presents an extension of the method to more efficient nonlinear approaches. Specifically, the use of a deep autoencoder is presented and discussed. The method is demonstrated for the design-space dimensionality reduction and hydrodynamic optimization of the hull form of a USS Arleigh Burke-class destroyer. A comparison with the linear method is finally shown and discussed. © 2018, (publisher Name). All Rights reserved.

Service robots are expected to operate in specific environments, where the presence of humans plays a key role. A major feature of such robotics platforms is thus the ability to react to spoken commands. This requires the understanding of the user utterance with an accuracy able to trigger the robot reaction. Such correct interpretation of linguistic exchanges depends on physical, cognitive and language-dependent aspects related to the environment. In this work, we present the empirical evaluation of an adaptive Spoken Language Understanding chain for robotic commands, that explicitly depends on the operational environment during both the learning and recognition stages. The effectiveness of such a context-sensitive command interpretation is tested against an extension of an already existing corpus of commands, that introduced explicit perceptual knowledge: This enabled deeper measures proving that more accurate disambiguation capabilities can be actually obtained. © 2017 Proceedings of the 1st Workshop on Language Grounding for Robotics, RoboNLP 2017 at the 55th Annual Meeting of the Association for Computational Linguistics, ACL 2017.

The water companies should provide services at the affordable tariffs for all people, irrespective of the water source, geographical area, size or complexity of water supply system. In order to contribute to the sustainability of water distribution infrastructure, tariffs should cover, in practice, at least the operating and maintenance costs. To obtain a lower water tariff, the water-energy nexus should be take into account. Thus, developing the innovative technological solutions which to allow new water pricing options and policy actions based on energy efficiency measures and Information and Communication Technologies (ICT) to implement the EU water policy represent a new research direction. The paper proposes an innovative solution represented by a software platform for a sustainable management of water supply systems which to include the advanced ICT solutions (Blockchain and Artificial Intelligence) and smart concepts (smart metering, demand response) with benefits both energy and water fields. The platform could lead to realize significant energy and savings through technical measures and a smart management, supplying the consumers with quality water at an affordable tariff considering the socio-economic factors.

Novel Information and Communication Technologies, such as Internet-of-Things (IoT), middleware and cloud computing, are providing innovative solutions ranging in different contexts. Smart health is one of these scenarios. Indeed, there is a rising interest in developing new healthcare services for remote patient assistance and monitoring. Among all, the main promised benefits consist on improving the patients' quality of life, speeding up therapeutic interventions and reducing hospitalizations' costs. This is also known as Telemedicine. In this paper, we present a novel distributed software infrastructure for remote monitoring of patients with chronic metabolic disorders: i) it collects and and makes available information coming from IoT devices, ii) it performs analysis to help medical diagnosis and iii) it promotes a bidirectional communication among the end-users (i.e. medical personnel and patients). In this paper, we also present our experimental results performed in a laboratory test environment to validate the proposed solution.

This paper presents an attempt to improve dynamic identification procedure for robotic manipulators, such that obtained models are appropriate for trajectory planning and motion control. In addition to algorithms development, authors bring new insights and arguments for the experiments organisation and analysis of the collected data. Significant part of the work is devoted to a case study in calibrating of a collaborative robot (co-bot) KUKA LWR4+, which represents a powerful tool for modern manufacturing systems. Therefore, refined models compared to the ones relied on CAD data provided by the manufacturer can be beneficial for various applications. © 2017

In this paper, we present a novel distributed software infrastructure to foster new services in smart grids with particular emphasis on supporting self-healing distribution systems. This infrastructure exploits the rising Internet-of-Things paradigms to build and manage an interoperable peer-to-peer network of our prototype smart meters, also presented in this paper. The proposed three-phase smart meter, called 3-SMA, is a low cost and open-source Internet-connected device that provides features for self-configuration. In addition, it selectively run on-board-algorithms for smart grid management depending on its deployment on the distribution network. Finally, we present the experimental results of Hardware-In-the-Loop simulations we performed.
