Special Issue on New Challenges in Robotics Technology
Authors: Raparelli Terenziano ,   Politecnico di Torino, Zobel Pierluigi Beomonte
Published: April 2017

Robotics has reached a top technological level in recent years, a level at which it can be successfully used not only in structured spaces (for less complex applications) but also increasingly in unstructured spaces. Robotics technology is now used effectively in hospitals for rehabilitation and assistive devices, in the home for domestic applications, in the space for autonomous robots and automated vehicles, in amusement parks for entertainment attractions, and on the ground for military applications. In industrial applications, robotics has enlarged its scope with high-speed robots, cooperative robots, and smart robotic devices for production set-ups. These new applications have created new challenges in robotics. New materials have been developed to make frames lighter and smarter, new actuators and sensors have been made in compliance with specific applications and for more advanced performance, new flexible gripper devices have been produced with superior control systems, and new interfaces have been developed that are integrated with the devices and easier to use. This special issue features 18 research articles related to the latest research results and practical case studies in robotics technology. Subjects include robots for rehabilitation, robots as assistive devices, robots for agriculture, robots for exploration, robots for automation and industrial applications, service robots, new actuators, new sensors, new gripping devices, new control strategies, and robotic systems. We deeply appreciate the careful efforts of all the authors and thank the reviewers for their incisive efforts. Without these contributions, this special issue could not have been printed. We hope that this special issue will trigger further research on robotics technology. Finally a special memory of Cesare Rossi, one of the authors, that died suddenly after the preparation of the manuscript.

In the last decade, the underwater activities performed by archaeologists and biologists have benefited from scientific research on the guidance, control, and sensory systems of unmanned vehicles. In fact, because underwater sites of interest are often difficult for divers to access, the use of unmanned vehicle technology to conduct surveys could be quite advantageous. In this paper, a novel and partially-biomimetic underwater robot, referred to as BRAVe (Biomimetic Research Autonomous Vehicle), is presented. For documentation purposes, it is equipped with a hybrid propulsion system, which consists of two different types of thrusters. The thrusters are designed to compensate for their reciprocal flaws in order to achieve a more efficient overall system. Specifically, the biomimetic thruster is employed for its superior energetic efficiency, and the horizontal propellers are exploited for accurate maneuvering. While the documentation and 3D reconstruction of the underwater seabed is a consolidated aspect for the authors, the hybrid propulsion system represents the main innovation of the present work. The increase in efficiency achieved by this propulsion system allows the vehicle to perform a thorough and precise documentation of underwater remains within short distances, while exploiting the maximum possible autonomy. This article discusses the details of the development of all the vehicle compartments and their associated characteristics, focusing on the significance of this technology. In addition, the results of 3D reconstructions extrapolated from images taken during real field missions are presented.

In recent years, robotics and automation technology have spread significantly throughout the agricultural harvesting sector. The increased productivity and the high cost of labour are some of the main reasons for this phenomenon. However, the harvesting of some crops is still carried out manually. One such crop is radicchio, which ripens at various times, thus requiring selective harvesting. This paper presents the development of an innovative modular system which aims at automating the harvesting of radicchio. Each module adopts a mechanical sensor to recognize the ripening status of the plant, on the basis of the hardness/compliance of its core. The module contains a cutting system, made of pneumatically actuated blades, and a harvesting system, made of two electrically powered tape conveyors. The module is intended to be used for a single row of radicchio cultivations using a tractor to move it. In laboratory tests the module prototype was manually moved. For this reason, the prototype is equipped with a control panel for monitoring and commanding. The conceived design, technical specifications and the prototype of the module are presented in detail. In addition, performances and functional tests are discussed. Finally, the functionality of the whole system is validated.

Authors: LÓPEZ FOLGADO Vicente
Published: April 2017

En este trabajo se aborda el contexto social y político que nutrió la vena satírica de J. Swift en su narración Los Viajes de Gulliver. De forma más concreta, se hace una aproximación a la Parte 4 que consiste en una mordaz denuncia del ser humano, como culpable de toda suerte de corruptelas morales. Esta sin par pieza subvierte los valores que detentan los despreciables yahoos humanos y los sabios e inocentes caballos. Finalmente, reviso algunas de las traducciones españolas más destacadas de la obra, señalando algunas diferencias entre los textos.
Introducción
Authors: AHUMADA Ignacio
Published: April 2017

Durante los años en que Antonio de Nebrija estuvo acogido al patronazgo de Juan de Estúñiga (1487-1504) trabajó en la redacción de un diccionario general de la lengua latina basado en “casi cuatrocientos mui aprovados autores”. Este diccionario sería la base para un segundo repertorio: un diccionario semibilingüe del español con el latín, esto es, un diccionario “en el cual interpretamos las palabras del romance i las bárbaras hechas ia castellanas añadiendo una breve declaración de cada una”. La impaciencia de su protector lo llevó a resolver este proyecto en lo que hoy conocemos como Lexicón o Diccionario latino-español (1492) y como Vocabulario o Diccionario español-latino (c 1495). Pasados unos años reestructuraría la idea original a partir de la redacción de un diccionario de derecho civil, otro de medicina y un tercero sobre las Sagradas Escrituras.

‘Un fiume piccolissimo di quel mare immenso’. Universalism, Navigation and the Rethinking of the Mediterranean in Campanella
Authors: DE LUCCA Jean-Paul
Published: April 2017

This contribution offers an intertextual reading of Tommaso Campanella’s early political writings and his utopia, The City of the Sun, with a view of bringing to the fore his stance on the radical shift in early modern maritime geopolitics. Campanella’s proposals for the establishment of world governance were informed by his enthusiasm for inventions such as the navigational compass, and by his emphasis on maritime prowess as a necessary condition for creating a universal monarchy. The dialogical and poetic character of The City of the Sun, and the choice of its imaginary interlocutors, may suggest an interpretation of Campanella’s utopia as a distinctively Mediterranean encounter between the ‘Old World’ and the ‘New World’. The transfer of knowledge and communication thus emerge as crucial lynchpins in Campanella’s project for universal reform and unity.
Stereotomy and the Mediterranean: Notes Toward an Architectural History
Authors: GALLETTI Sara
Published: April 2017

Stereotomy, the art of cutting stones into particular shapes for the construction of vaulted structures, is an ancient art that has been practiced over a wide chronological and geographical span, from Hellenistic Greece to contemporary Apulia and across the Mediterranean Basin. Yet the history of ancient and medieval stereotomy is little understood, and nineteenth- century theories about the art’s Syrian origins, its introduction into Europe via France and the crusaders, and the intrinsic Frenchness of medieval stereotomy are still largely accepted. In this essay, I question these theories with the help of a work-in-progress database and database-driven maps that consolidate evidence of stereotomic practice from the third century BCE through the eleventh century CE and across the Mediterranean region. I argue that the history of stereotomy is far more complex than what historians have assumed so far and that, for the most part, it has yet to be written.
The Ibn Ezra–Henry Bate Astrological Connection and the Three Abrahams
Authors: SELA Shlomo
Published: April 2017

This paper studies the astrological connection between Abraham Ibn Ezra (ca. 1089–ca. 1161), who created the first comprehensive corpus of Hebrew astrological textbooks that address the main systems of Arabic astrology, and Henry Bate (1246–1310), who first translated into Latin a collection of Ibn Ezra’s astrological writings and brought Ibn Ezra to the knowledge of the Latin West. The first part of this paper offers a brief chronological survey of how Henry Bate became acquainted with Ibn Ezra’s astrological treatises. The second part focuses on a surprising element: when Bate refers to astrological treatises that we now know were written by Ibn Ezra, he assigns them to one of three different authors. All three are ‘Abraham’, but they have distinguishing cognomens. Here we determine which astrological treatises Bate assigned to each of the three Abrahams, try to identify the historical figure behind each of them, and explain Bate’s reason for trisecting Abraham Ibn Ezra.

Challenging behaviour in school – special education teachers’ perceptions
Authors: Hämeenaho Pilvi
Published: April 2017

This article explores the challenges that special education teachers encounter during their daily work in Finnish schools. The main focus is in those challenges which cause worry among teachers, especially aggressive behavior in class rooms and school area. This article scrutinizes the reasons and consequences of a problem from the perspective of special education teachers. The research shows, how problems are mainly caused by delays in assessments, treatments and rehabilitation for pupils with mental or behavioral disorders. The analysis shows how on teachers’ opinion, challenging situations, which induce great worry occur when pupil has a need for psychiatric treatment but had not received it in time. In these kind of situations teachers feel frustrated and partly helpless as their professional skills and knowledge is not enough to provide the support pupil needs. When the neediest pupils do not receive support and treatment in time, it leads to situation where special education teachers have to provide support and face pupils’ challenging behavior even if they may not have measures for it.

Building interfaith relationship is a relevant topic for people who live in the plurality of religions and beliefs. All religions are called to maintain diversity by building interfaith relationship. A true brotherhood is the objective of building interfaith relationship. There are various ways which could be taken by religions in building interfaith relationship. Those ways could be found in all spheres of human life. One way which could be required by religions in building interfaith relationship is to go through the wisdom of local communities. This way can lead the religions to be present relevantly and contextually in society. According to the author, the local wisdom of Keiese (Kei) community has a relevance to the efforts of building interfaith relationship. The values of Keiese (Kei) local wisdom are in accordance with the universal values on religions, which could be used as a powerful way in building interfaith relationship up.
Sejarah Gereja Belanda Austin Friars di City of London: Refleksi Sejarah Gerakan Reformasi � Harapan dan Tantangan
Authors: Napel Henk Ten
Published: April 2017

In the centre of the City of London one can find the Dutch Church Austin Friars. Thanks to the Charter granted in 1550 by King Edward VI, the Dutch refugees were allowed to start their services in the church of the old monastery of the Augustine Friars. What makes the history of the Dutch Church in London so special is the fact that the church can lay claim to being the oldest institutionalised Dutch protestant church in the world. As such it was a source of inspiration for the protestant church in the Netherlands in its formative years during the sixteenth century. Despite its long history, the Dutch Church is still alive and well today. This article will look at the origin of this church and the challenges it faced and the developments it experienced during the 466 years of its existence.
Testing for explosive bubbles in the South African-US exchange rate using the sequential ADF procedures
Authors: Elike Uchenna , Anoruo Emmanuel
Published: April 2017

This paper tests for the existence of speculative bubbles in the South African-US exchange rate using the sequential ADF procedures. In particular, the paper uses the SADF and GSADF right-tailed unit root tests to explore the existence of explosive bubbles in the South African-US exchange rate for the time period running from January1980 through July 2012. The results provide evidence in support of the existence of explosive bubbles in the nominal rand-dollar exchange rate, the real exchange rate of traded and non-traded goods. The explosive behavior exhibited by the South African rand-US dollar exchange rate can be interpreted as evidence of rational bubbles given that this behavior is driven by the fundamentals including relative prices of traded and non-traded goods.
A New Reconstructive Technique of the Anterolateral Ligament with Iliotibial Band-Strip
Authors: Stuyts Bart , Van den Eeden Elke , Victor Jan
Published: April 2017

Background:

Anterior cruciate ligament (ACL) reconstruction is a well-established surgical procedure for the correction of ACL ruptures. However, the incidence of instability following ACL reconstruction is substantial. Recent studies have led to greater insight into the anatomy and the radiographic characteristics of the native anterolateral ligament (ALL), along with its possible role in residual instability after ACL reconstruction.

Method:

The current paper describes a lateral extra-articular tenodesis to reconstruct the ALL during ACL procedures, using a short iliotibial band strip. The distal insertion of this strip is left intact on the anterolateral side of the proximal tibia, and the proximal part is fixed at the anatomic femoral insertion of the ALL.

Results:

Our technique avoids the sacrifice of one of the hamstring tendons for the ALL reconstruction. Additionally, there is no interference with the anatomical location or function of the LCL.

Conclusion:

Our technique offers a minimally invasive and nearly complete anatomical reconstruction of the ALL with minimal additional operative time.

Authors: Bohlouli Babak , Jackson Terri Jurgens , Tonelli Marcello , Hemmelgarn Brenda , Klarenbach Scott
Published: April 2017

Background

and objectives Patients with CKD are at risk of hospital-acquired complications (HACs). We sought to determine the association of preventable HACs with mortality, length of stay (LOS), and readmission.

Design, setting, participants, & measurements

All adults hospitalized from April of 2003 to March of 2008 in Alberta were characterized by kidney function and occurrence of preventable HACs. CKD was defined by eGFR<60 ml/min per 1.73 m2 and/or albumin-to-creatinine ratio >3–30 mg/mmol for >3 months in the time frame from 365 to 90 days before admission. Regression models examined the association of HACs with outcomes.

Results

Of 536,549 hospitalizations, 8.5% (n=45,733) had CKD and 9.8% of patients with CKD had one or more potentially preventable HAC. In patients with potentially preventable HACs, proportions of death within index hospitalization and from discharge to 90 days were 17.7% and 6.8%, respectively. In patients with CKD, comparing with those hospitalizations without potentially preventable HACs, the adjusted odds ratio (OR) of mortality during index hospitalization and from hospital discharge to 90 days in patients with one or more preventable HAC was 4.67 (95% confidence interval [95% CI], 4.17 to 5.22) and 1.08 (95% CI, 0.94 to 1.25), respectively. Median incremental LOS in patients with one or more preventable HAC was 9.86 days (95% CI, 9.25 to 10.48). The OR for readmission with preventable HAC was 1.24 (95% CI, 1.15 to 1.34). In a cohort with and without CKD, the adjusted ORs of mortality during index hospitalization in patients with CKD and no preventable HACs, patients without CKD and with preventable HACs, and patients with CKD and preventable HACs were 2.22 (95% CI, 1.69 to 2.94), 5.26 (95% CI, 4.98 to 5.55), and 9.56 (95% CI, 7.23 to 12.56), respectively (referenced to patients without CKD or preventable HACs).

Conclusions

Preventable HACs are associated with higher mortality, incremental LOS, and greater risk of readmission, especially in people with CKD. Targeted strategies to reduce complications should be a high priority.

Aim:
To investigate the cost–effectiveness of blue-light therapy versus a two-compound formulation (TCF) (Dovobet
®
gel [calcipotriol and betamethasone]) in mild-to-moderate psoriasis.
Methods:
A Markov model was applied to describe the course of disease among Dutch patients with a Psoriasis Area and Severity Index (PASI) score ≤ 10 over a 52-week time horizon. Patients received either 12-week blue-light therapy or two 4-week treatments with TCF. Patients, experiencing no PASI reduction after either therapy, were assumed to receive 12-week ultraviolet B phototherapy.
Results:
There was no significant difference in PASI reduction between two interventions (71 vs 72%). However, blue-light therapy was associated with a cost savings of EU€248.
Conclusion:
Treatment of mild-to-moderate chronic plaque psoriasis using blue-light therapy may be more cost-effective than TCF.
Inovação, desenvolvimento e espaço urbano: uma relação necessária mas não suficiente
Authors: Dallabrida Valdir Roque , Covas Maria das Mercês Cabrita mendonça , Covas António Manuel Alhinho
Published: April 2017

Há uma relação intrínseca entre inovação, desenvolvimento e espaço urbano, desde as abordagens teóricas clássicas até as contemporâneas. As variadas abordagens diferem quanto aos fatores decisivos de inovação. Eis a questão instigante: em que contribuíram tais abordagens para avançarmos enquanto civilização, ou seja, até que ponto a relação triangular, apesar de necessária, é suficiente? Objetivamente, tomamos o espaço urbano como foco principal, por ser considerado o lócus privilegiado na origem dos processos de desenvolvimento. Todavia, essa relação não pode ser simplesmente instrumental e/ou funcional, uma vez que a cidade pode gerar inúmeras disfunções, quer no seu interior, quer no seu entorno territorial. Quer dizer, temos uma cidade criativa e tecnologicamente avançada, mas temos, também, uma cidade desigual, guetizada e civicamente pobre. Por causa desse aparente paradoxo, o texto propõe um padrão de desenvolvimento integrador, mais inteligente, mais inclusivo, mais eclético, ou seja, eticamente mais responsável perante os seus cidadãos.

OBJECTIVE

Plasma glycated CD59 (pGCD59) is an emerging biomarker in diabetes. We assessed whether pGCD59 could predict the following: the results of the glucose challenge test (GCT) for screening of gestational diabetes mellitus (GDM) (primary analysis); and the diagnosis of GDM and prevalence of large for gestational age (LGA) newborns (secondary analyses).

RESEARCH DESIGN AND METHODS

Case-control study of 1,000 plasma samples from women receiving standard prenatal care, 500 women having a normal GCT (control subjects) and 500 women with a failed GCT and a subsequent oral glucose tolerance test (case patients).

RESULTS

Compared with control subjects, the median (interquartile range) pGCD59 value was 8.5-fold higher in case patients and 10-fold higher in GDM patients, as follows: control subjects 0.33 (0.19); case patients 2.79 (1.4); GDM patients 3.23 (1.43) (P < 0.001); area under the receiver operating characteristic curve 0.92. LGA prevalence was 4.3% in the lowest quartile and 13.5% in the highest quartile of pGCD59.

CONCLUSIONS

One pGCD59 measurement during weeks 24–28 identifies pregnancy-induced glucose intolerance with high sensitivity and specificity and can potentially identify the risk for LGA.

This paper presents the design of a scaled-down prototype of a proposed for a cooling system on environments for replacement of air conditioners by compressor. The operation of the proposed system differs from current systems by compressor to be a system based on the Peltier effect (thermoelectric modules) controlled by PWM ensuring maximum efficiency and precise control of the desired temperature. The prototype foresee the removal of air from the external environment (environment), making him circular of forced mode by a channel which will have its temperature reduced by heat exchange that occurring by indirect contact with the cold surface of the thermoelectric modules, thus arriving to at the environment to be cooled with temperature reduced at relative temperature taken by outside. The system is sensed and controlled via PWM modulation of a electronic apparatus comprising an temperature sensors LM35, development kit ARDUINO UNO and LABVIEW 2014 software which together aim to ensure efficient temperature control and efficiency in the consumption of electrical energy. It is presented in this paper the experimental development of prototype and its validation, thus confirming the technical feasibility of construction of an air conditioner using thermoelectric modules.

Prototype of a simplified polar heliostat suitable for integration in buildings
Authors: M. Torres Roldán  , M. Varo-Martínez  , R. López-Luque
Published: April 2017

The increasing improvement of energy sustainability entails a raise in the use of heliostats in small applications. These devices aim to use direct radiation as a source of natural lighting, and they are also used as components for concentration systems in thermal and photovoltaic applications. Most technological developments published about heliostats up to now refer to concentration tower thermosolar power plants. Furthermore, they are orientated towards heliostats of big dimensions with large distances between the reflector and the focus. It is different, however, for urban applications, where smaller heliostats and lower distances travelled by reflected rays are proposed, and, consequently, greater errors in solar tracking are allowed. This paper describes a new simple heliostatic system suitable for small applications. The main feature of this system is the possibility of controlling several heliostats with a unique engine. It must be highlighted that the system proposed uses a simple logic and has an easy electronic controller implementation.

Published: April 2017

The electricity consumption behavior in Brazil has been extensively investigated over the years due to financial and social problems. In this context, it is important to simulate the energy prices of the energy efficiency auctions in the Brazilian regulated environment. This paper presents an approach to generate samples of auction energy prices in energy efficiency market, using Markov chain Monte Carlo method, through the Metropolis-Hastings algorithm. The obtained results show that this approach can be used to generate energy price samples.

The paper deals with photovoltaic (PV) systems able to generate reactive power and to curtail active power generation. Based on measurements performed on an existing PV system over 10 years its typical yearly operation profile is determined. It is used to evaluate the ability of the PV system to generate reactive power. After that the efficiency characteristic of a micro-inverter is determined experimentally. It is described as a function of generated active and reactive powers. This function is afterwards used in an optimization procedure, where measured time dependent load and power generation profiles are applied to determine optimal reactive power generation in PV systems installed in an existing low voltage network. Based on calculations performed over one year, the impact of reactive power generation on yearly production of electrical energy in PV systems is evaluated.

The present study lies in the evaluation of a so-called scale model methodology to validate different aspects of the core topology of phase planar actuator, which has a movement on the plane with two degrees of freedom from a single device traction being formed by a carriage, called primary, composed of two independent three-phase windings and a stator also called secondary, formed by a flat aluminum plate mounted on a ferromagnetic core also plane, enclosing the primary drive area. Thus, the work focuses on the analysis of experimental and numerical modeling of electromagnetic phenomena involved with employing a core reduced as the complete core validation methodology. In order to measure their performance is evaluated by force propelling the two models cores.

Published: April 2017

Energy crisis is one of the most important issues in today’s world. Conventional energy resources are limited and are one of the primary reasons for pollution and global warming. The use of renewable energy is becoming increasingly popular. Solar energy is rapidly gaining ground as an important mean of expanding renewable energy use. Solar tracking is employed in order to maximize solar radiation collection by a photovoltaic panel. In this paper we present the design, fabrication, and testing of an active dual axis closed loop solar tracking sensor. The compactness of the design facilitates its easy mounting on any surface or place exposed to solar irradiance. The solar irradiance is detected by an Organic Photovoltaic Cell (OPV) which scans the sky for the maximum power point. Different modes of operation have been accommodated in a single generic mode which stops operation at night and facilitates night return of the panel(s) the sensor is connected to. This system is independent with respect to geographical location of the solar panel and diurnal as well as seasonal variations. This sensor can be effectively employed in efficient solar energy extraction for systems of any scale. The operation of the system is also independent with respect to the initial configuration and the starting conditions. The experimental testing shows agreement with true sun coordinates with a satisfactory degree of accuracy. This work can be extended to reduce the scan time of the sensor.

Optimising the use of a battery in a wind-diesel-battery hybrid island grid using power prediction and day-ahead optimisation
Authors: W.-G. Früh
Published: April 2017

Using demand and local renewable generation data, the performance of a hybrid wind-diesel-battery island grid was assessed for a range of scheduling approaches, ranging from simple prioritising of the battery over diesel, through a simple assessment of expected day-ahead demand-wind generation balance to a day-ahead optimisation. A key factor in the performance assessment was a nonlinear cost of using the battery, where the cost depended on the state of charge of the battery, reflecting how the life time of many batteries depends on their depth of discharge. The results suggested that a simple assessment of the day-ahead balance may increase the operational costs compared to immediate battery prioritisation but combining forecasts with optimisation can lead to reliable operational cost savings.

This paper presents the design of the One-Degree of Freedom Internal Model Control structure (1-DOF IMC) applied to a single-phase grid-connected inverter. It is presented the mathematical model of the inverter and its LCL filter, used to project the 1-DOF IMC controller, and it is analyzed the internal feedback compensation corresponding to the decoupling of grid voltage provided by a feedforward strategy. In order to establish a comparison base, the grid connected system is also evaluated using a Proportional–Resonant Controller (P-Res). Simulations results of both controllers are presented, which allows the comparison between the 1-DOF IMC and P-Res control performances.

This paper presents a dynamics study of the Switched Reluctance Generator (SRG) dynamics when connected to a three-phase AC power grid. A mathematical model that includes magnetic saturation is used to represent the SRG, which is driven by an asymmetric half bridge converter. Output generated voltage is smoothed with a shunt capacitor leading to a DC link voltage. This voltage is regulated using a PI compensator that controls the magnetizing angle of the generator phases. It is shown that putting a freewheeling stage between the magnetizing and the demagnetizing states per phase, allows the best use for a better usage of the mechanical power in electromechanical conversion process. Injection of active power in the grid is performed by two PI compensators that determine the modulation indexes to each sinusoidal PWM modulators that drive the three phases of the converter. This work also proposes the implementation of an islanding detection method for distributed generation (DG) systems. This method is based on voltage and frequency parameters detection. It proved to be robust and useful to detect the islanding under different load conditions and the output of the power grid.

Published: April 2017

The paper presents the lumped parameters of EMI filters that must be used in the design process. In order to obtain consistent results, apart from the conventional parameters and stress de-rating factors (power dissipation, limiting voltage and current, operating temperature range, etc.), one should think also in terms of nonideal behaviour of the circuit elements in the equivalent model. Following this conduct the calculated filter characteristics (attenuation or insertion loss) will gain in accuracy.

Solar nanoantennas appear a very interesting solution to exploit solar radiation, as a matter of fact, their operating principle allows heat losses to be lessened compared to traditional photovoltaic cells and efficiency to be increased. Anyway, some technological issues are to be overcome. Literature often proposes a characterization by radiation efficiency typical of traditional antennas. Since the aim of solar nanoantennas is to harvest energy, in this paper the most promising devices are characterized by the upper bound of deliverable power density calculated in the whole operating wavelengths range.

Authors: S. Raimondi Cominesi  , A. Del Corno  , E. Corsetti  , G. A. Guagliardi  , C. Sandroni  , R. Scattolini
Published: April 2017

This paper presents an algorithm for the management of electrical and thermal power production in microgrids connected to the utility grid and subject to uncertainties in both load requests and non-dispatchable generation. The suggested procedure allows, on one hand, to obtain the day ahead setpoint profiles for the microgrid devices, resulting in the economic optimal power exchange with the grid. On the other hand, it supplies a suitable method to refine such setpoint profiles, during the daily execution, in order to cope with unpredicted behaviours of the system. A formulation of the algorithm for a possible case study is given and simulation results are illustrated in the final part of the work.

Industrial equipment is evolving towards data gathering and communication, following the Internet of things approach. During last years, different management systems and related standards have been developed, in order to raise the performance of manufacturing processes. But a complete optimization of a manufacturing process requires a holistic approach, and adopting microgrid architectures can actually empower the optimization of a manufacturing process. In this paper, synergies about microgrids and manufacturing processes planning will be pointed out. Thus, a suitable approach to MG planning for manufacturing companies from a Knowledge Discovery in Databases (KDD) point of view is described.

Published: April 2017

The large increase in renewable energy sources (RES-E) penetration in the European Union (EU) has raised the concern of policy makers about the costs of public promotion of RES-E, in spite of the commitment of the European Commission to the deployment of RES-E in the last years. This paper is focused on wind energy, because it is the renewable technology with the highest contribution to electricity mix in Europe (excluding hydro). An economic analysis of wind energy contribution should not only take into account the policy costs of the deployment, which are finally paid by electricity consumers, but also its benefits, particularly those related to climate change mitigation and the reduction of fossil fuel dependence distributed among citizens. The aim of this paper is to fill this gap and evaluate the policy costs and the most relevant benefits of wind energy deployment in the EU28 (28 Member States) using 2013 data. For this purpose, an innovated methodology internationally validated has been used. The results show that the benefits considered are relevant and should be taken into account when support costs are assessed and in the future development of energy policies in Europe.
