SFDL: MVC Applied to Workflow Design

Process management based on workflow systems is a growing trend in collaborative environments. One of the most notorious areas of improvement is that of user interfaces, especially since business process definition languages do not address efficiently the point of contact between workflow engines and human interactions. With that in focus, we propose the MVC pattern design to workflow systems. To accomplish this, we have designed a new dynamic view definition language called SFDL, oriented towards the easy interoperability with the different workflow definition languages, while maintaining enough flexibility to be represented in different formats and being adaptable to several environments. To validate our approach, we have carried out an implementation in a real banking scenario, which has provided continuous feedback and enabled us to refine the proposal. The work is fully based on widely accepted and used web standards (XML, YAML, JSON, Atom and REST). Some guidelines are given to facilitate the adoption of our solution

RJEŠAVANJE NEUOBIČAJENO VELIKIH BRZINA SEIZMIČKI NERAZLUČIVIH UPORABOM SINTETIČKIH MODELA, POLJE PENOBSCOT, KANADA

Penobscot Field is located in the Sable Sub-basin in Nova Scotia, Canada, where a 3D seismic acquisition campaign was carried out in 1991 and also two oil wells were previously drilled (L-30 and B-41). In the interpreted seismic data, a discrepancy was found in the travel times of the seismic waves near well B-41, causing a false structural height in the Naskapi Member, Mississauga Formation (Early Cretaceous or Lower Cretaceous) and deeper formations (10 to 15 ms, i.e. approximately 25 m). It was decided to find a solution of this problem using synthetic models. First, making a delimitation of the study area by means of a seismic subcube, which were later interpreted surfaces of interest, through the well data. The average velocity and density properties were found for each interpreted strata. Subsequently, a 2D seismic acquisition was simulated, choosing a line that crossed both wells and through the use of ray traces, synthetic shot gathers were obtained and processed through the use of different seismic migration tests, and the final solution was found to be Kirchhoff pre-stacking migration in depth.Polje Penobscot nalazi se u subbazenu Sable u Novoj Škotskoj, Kanada. Tamo je 1991. načinjeno 3D seizmičko snimanje te su izbušene dvije naftne bušotine (L-30 i B-41). U interpretiranim seizmičkim podatcima uočeno je odstupanje u očekivanim seizmičkim brzinama u okolici bušotine B-41. Tako je ocrtano lažno strukturno uzdignuće unutar člana Naskapi (formacija Missisauge) i dublje (anomalija od 10 do 15 ms ili približno 25 m). Odlučeno je taj problem riješiti uporabom sintetičkih modela. Prvo su određeni volumeni seizmičke kocke, zatim površine za analizu te su uporabom bušotinskih podataka izračunane prosječne brzine i gustoća za svaki interpretirani sloj. Nakon toga je načinjen 2D seizmički model, koji je obuhvatio obje bušotine, praćenje sintetskih oblika, te Kirchhoffovu preseizmičku i postseizmičku dubinsku migraciju

PREPOZNAVANJE ANOMALIJE PROUZROČENE VELIKOM BRZINOM SEIZMIČKIH VALOVA (NEOPAZIVE NA SKALI SEIZMIČKE RAZLUČIVOSTI) INTEGRACIJOM SEIZMIČKIH SVOJSTAVA, PRIMJER POLJA PENOBSCOT, KANADA

Penobscot Field is located in the Sable Sub-basin, in the Nova Scotia Basin, belonging to the Canadian territory, and for the year of 1991, a 3D seismic acquisition was carried out in this region. Also, two exploratory wells were previously drilled (L-30 and B-41). Then, with the subsequent interpretation of the area, a discrepancy was found around 10ms to 15ms (approximately 25m) in the travel times of the seismic waves in the vicinity of well B-41, resulting in a false structural high in the Mississauga Formation and Naskapi Member. It is possibly caused by changes in geological facies and thickness of the Wyandot formation, consequently, B-41 well became dry. For these reasons, to identify the possible problem which caused everything mentioned above, the area between the wells was delimited by a seismic subvolume (by reducing the seismic cube), making a seismic interpretation of the top of the formations of interest, as well as an analysis of certain petrophysical properties in the wells, in order to delimit the thickness of the anomaly and, consecutively, the use of the seismic attributes for lateral identification of the anomaly in the Wyandot Formation.Polje Penobscot nalazi se u podnožju Sable, u bazenu Nova Škotska koji pripada kanadskomu području, gdje je 1991. godine načinjeno 3D seizmičko snimanje. Prethodno su izbušene dvije istraživačke bušotine (L-30 i B-41). Zatim je, uz dodatnu interpretaciju, otkriveno vrijeme prolaska 10 do 15 ms (otprilike 25 metara) seizmičkih valova u blizini bušotina B-41, što je rezultiralo interpretacijom „lažnih” struktura unutar «lanova Missisauga i Naskapi. To je vjerojatno uzrokovano promjenama u sastavu i debljini Wyandotove formacije. Prepoznavanje uzroka lažnih signala bušotina B-41 dobro je izvedeno. Prepoznavanjem lažnih ocrta bilo je moguće područje između dviju spomenutih bušotina ocrtati kao seizmički podvolumen, odnosno kao dio „seizmičke kocke”. Time je seizmička interpretacija postala strukturno ispravna, uz dodatno omogućavanje analize određenih petrofizičkih svojstava u bušotinama. Nadalje, utvrđena je debljina područja „anomalnoga” odziva, kako po okomici tako i bočno, a unutar formacije Wyandot

PV Hosting Capacity Analysis and Enhancement Using High Resolution Stochastic Modeling

Reduction of CO2 emissions is a main target in the future smart grid. This goal is boosting the installation of renewable energy resources (RES), as well as a major consumer engagement that seeks for a more efficient utilization of these resources toward the figure of ‘prosumers’. Nevertheless, these resources present an intermittent nature, which requires the presence of an energy storage system and an energy management system (EMS) to ensure an uninterrupted power supply. Moreover, network-related issues might arise due to the increasing power of renewable resources installed in the grid, the storage systems also being capable of contributing to the network stability. However, to assess these future scenarios and test the control strategies, a simulation system is needed. The aim of this paper is to analyze the interaction between residential consumers with high penetration of PV generation and distributed storage and the grid by means of a high temporal resolution simulation scenario based on a stochastic residential load model and PV production records. Results of the model are presented for different PV power rates and storage capacities, as well as a two-level charging strategy as a mechanism for increasing the hosting capacity (HC) of the network

Analysis of Colombian Seismicity as a Way to Explain and Understand The Bucaramanga Nest

Colombia is region with high seismicity due to the convergence of Panama Block, Nazca and Caribbean plates with the South American Plate, however there is a complex area named The Bucaramanga Nest which was the motive of this research means of its complexity, being that there have been different studies which have not been able to explain the reason of this phenomenon, for that motive this work has as objective finding this answer by the use of 3679 earthquake information in Colombia, with a Mw higher than 3.5. Having information from all the earthquakes, they were localized on its epicenters to notice how they were distributed, after that, five lines were chosen to make, along them, The Benioff Zone, obtaining the geometry of the slabs for Nazca and Caribbean plates, knowing the angle of subduction of them and how it changed, also, thirty earthquakes near the five lines were selected to see the focal mechanisms along the slabs and knowing the fault system in The Bucaramanga Nest. Beside all it was said before, it was modeled an approximation of the subduction zones by a contour map along the studied region. At the end, it was able to reach an answer about the reason of why The Bucaramanga Nest happened, defining its vertical and lateral extension too

Cross-Platform Implementation of an SSVEP-Based BCI for the Control of a 6-DOF Robotic Arm

[EN] Robotics has been successfully applied in the design of collaborative robots for assistance to people with motor disabilities. However, man-machine interaction is difficult for those who suffer severe motor disabilities. The aim of this study was to test the feasibility of a low-cost robotic arm control system with an EEG-based brain-computer interface (BCI). The BCI system relays on the Steady State Visually Evoked Potentials (SSVEP) paradigm. A cross-platform application was obtained in C++. This C++ platform, together with the open-source software Openvibe was used to control a Staubli robot arm model TX60. Communication between Openvibe and the robot was carried out through the Virtual Reality Peripheral Network (VRPN) protocol. EEG signals were acquired with the 8-channel Enobio amplifier from Neuroelectrics. For the processing of the EEG signals, Common Spatial Pattern (CSP) filters and a Linear Discriminant Analysis classifier (LDA) were used. Five healthy subjects tried the BCI. This work allowed the communication and integration of a well-known BCI development platform such as Openvibe with the specific control software of a robot arm such as Staubli TX60 using the VRPN protocol. It can be concluded from this study that it is possible to control the robotic arm with an SSVEP-based BCI with a reduced number of dry electrodes to facilitate the use of the system.Funding for open access charge: Universitat Politecnica de Valencia.Quiles Cucarella, E.; Dadone, J.; Chio, N.; García Moreno, E.

The Public and the Cine in Spain. Issues of identity and brand

El cine español ha sufrido una serie de vicisitudes a lo largo de su historia que han marcado tanto su producción, como el desarrollo de una industria solvente y sólida, y la valoración que de la misma ha hecho el público de cada época. Las relaciones que se han establecido entre el ciudadano español en la oferta cinematográfica realizada no han sido las más adecuadas para que la convivencia fuera eficaz. Desde la profesión no se ha hecho el esfuerzo por transmitir una imagen eficaz que pudiera consolidar la marca necesaria para el reconocimiento de la industria. Todas las partes intervinientes en el desarrollo de esta industria han sobrevivido a las novedades sin plantearse seriamente cómo afrontar cada uno de los retos que se le fueron presentando. El resultado no es otro que, en el momento presente, han de involucrarse en recuperar el tiempo perdido si realmente quieren seguir manteniendo activo el negocio. Posibilidades, todavía las hay, pero es necesario el empeño manifiesto de las instituciones, profesionales y público español.Spanish cinema has suffered a series of troubles along its history. They have determined its production, along with the development of a solvent and solid industry. This trajectory has also had influence in the assessment of the audience. The relationships developed between the Spanish audience and the cinema offer haven’t favored their coexistence. From the profession, the effort to transmit an effective image hasn’t achieved to consolidate the necessary branding for the recognition of the industry. All the parts involved in the development of this industry have survived the novelties without seriously consider how to deal with each one of the new challenges. At present, the result is that all those parts involved must join to update the business to keep it active. There are possibilities yet, but a clear determination is needed from the institutions, professionals and the Spanish audience

Predictive Fault Diagnosis for Ship Photovoltaic Modules Systems Applications

[EN] In this paper, an application for the management and supervision by predictive fault diagnosis (PFD) of solar power generation systems is developed through a National Marine Electronics Association (NMEA) 2000 smart sensor network. Here, the NMEA 2000 network sensor devices for measuring and supervising the parameters inherent to solar power generation and renewable energy supply are applied. The importance of renewable power generation systems in ships is discussed, as well as the causes of photovoltaic modules (PVMs) aging due to superimposed causes of degradation, which is a natural and inexorable phenomenon that affects photovoltaic installations in a special way. In ships, PVMs are doubly exposed to inclement weather (solar radiation, cold, rain, dust, humidity, snow, wind, electrical storms, etc.), pollution, and a particularly aggressive environment in terms of corrosion. PFD techniques for the real-world installation and safe navigation of PVMs are discussed. A specific method based on the online analysis of the time-series data of random and seasonal I¿V parameters is proposed for the comparative trend analyses of solar power generation. The objective is to apply PFD using as predictor symptom parameter (PS) the generated power decrease in affected PVMs. This PFD method allows early fault detection and isolation, whose appearance precedes by an adequate margin of maneuver, from the point of view of maintenance tasks applications. This early detection can stop the cumulative degradation phenomenon that causes the development of the most frequent and dangerous failure modes of solar modules, such as hot-spots. It is concluded that these failure modes can be conveniently diagnosed by performing comparative trend analyses of the measured power parameters by NMEA sensors.García Moreno, E.; Quiles Cucarella, E.; Zotovic Stanisic, R.; Gutiérrez, SC.

Permission from IEEE must be obtained for all other users, including reprinting/ republishing this material for advertising or promotional purposes, creating new collective works for resale or redistribution to servers or lists, or reuse of any copyrighted components of this work in other works."This paper proposes a new method for fault diagnosis in electric power systems based on neural networks. With this method the diagnosis is performed by assigning a neural module for each type of component of the electric power system, whether it is a transmission line, bus or transformer. The neural modules for buses and transformers comprise two diagnostic levels which take into consideration the logic states of switches and relays, both internal and back-up. The neural module for transmission lines also has a third diagnostic level which takes into account the oscillograms of fault voltages and currents, as well as the frequency spectrums of these oscillograms, in order to verify if the transmission line had in fact been subjected to a fault. One important advantage of the diagnostic system proposed is that its implementation does not require the use of a network configurator for the system; it does not depend on the size of the power network, nor does it require retraining of the neural modules if the power network increases in size, making its application possible to only one component, a specific area, or the whole context of the power system..Flores, A.; Quiles Cucarella, E.; García Moreno, E.; Morant Anglada, FJ.

May the evaluation of nitrosative stress through selective increase of 3-nitrotyrosine proteins other than nitroalbumin and dominant tyrosine-125/136 nitrosylation of serum α-synuclein serve for diagnosis of sporadic Parkinson's disease?

Nitrosative stress, where nitrosylation of tyrosine (Tyr) leading to 3-nitrotyrosine proteins or free 3-nitrotyrosine is the most prominent change, has been proposed as a pathogenic mechanism in Parkinson's disease (PD). Levels of 3-nitrotyrosine proteins in serum and cerebrospinal fluid (CSF) of patients with PD have not been studied. Nitrosative stress-induced protein changes in serum and CSF were analyzed in patients with PD (n=54) and controls (n=40). Herein, we demonstrate the presence of nitrosative stress in serum and CSF of patients with early PD leading to selective increase of 3-nitrotyrosine proteins other than nitroalbumin, without free 3-nitrotyrosine (Hoehn-Yahr stage 1, p<0.05; stage 2, p<0.01). Among 3-nitrotyrosine proteins, nitro-α-synuclein (N-αSyn) was detected in serum, not CSF, and the sites of Tyr nitrosylation were observed to be modified in patients with early PD. Thus, the intensity of nitrosylation of Tyr125/136 residues is enhanced (stage 1, p<0.05; stage 2, p<0.01), and that of the Tyr39 site is reduced (stage 1, p<0.05), and the ratio between both parameters (α-synuclein with nitrosylated tyrosines 125 and 136 [N-αSyn-Tyr125/136]:α-synuclein with nitrosylated tyrosine 39 [N-αSyn-Tyr39] ratio) is significantly higher in patients with early PD (p<0.01). These observations lead to the hypothesis that evaluating nitrosative stress through enhanced levels of 3-nitrotyrosine proteins in serum and CSF without changes in nitroalbumin, together with the profile of tyrosine nitrosylation of serum αSyn characterized by dominant nitrosylation of Tyr125/136, could serve for the diagnosis of sporadic PD.Instituto de Salud Carlos III RD09/0076/00080Ministerio de Sanidad RETICS, RD06/ 001/002Ministerio de Sanidad RETICS, RD06/010/1007Unión Europea FEDER, European Fund for Regional Developmen
