The KM3NeT research infrastructure being built at the bottom of the Mediterranean Sea will host water-Cherenkov telescopes for the detection of cosmic neutrinos. The neutrino telescopes will consist of large volume three-dimensional grids of optical modules to detect the Cherenkov light from charged particles produced by neutrino-induced interactions. Each optical module houses 31 3-inch photomultiplier tubes, instrumentation for calibration of the photomultiplier signal and positioning of the optical module and all associated electronics boards. By design, the total electrical power consumption of an optical module has been capped at seven watts. This paper presents an overview of the front-end and readout electronics system inside the optical module, which has been designed for a 1 ns synchronization between the clocks of all optical modules in the grid during a life time of at least 20 years.

IEEE PES Transmission and Distribution Conference and Exposition

Frequency regulation becomes a non-trivial issue due to an increase in renewable resources and power electronics-based loads. Direct load control (DLC), a strategy of autonomous demand response, has been applied to mitigate operational burdens on generation units for frequency regulation. Variable speed heat pumps (VSHPs) have been regarded as promising devices that can respond to the DLC signal updated every 2 or 4 seconds. This paper presents a dynamic model of the VSHP that is simplified for real-time simulation studies but still sufficiently comprehensive to analyze its physical and operational characteristics. Furthermore, a variable speed drive (VSD)-controlled induction motor model is designed together with an indirect torque controller for the adjustment of the VSHP input power. In addition, based on experimental setup and data, a test room was modeled to estimate the effect of the DLC-enabled VSHP on indoor temperature. Simulation case studies performed in Matlab/Simulink verify that the VSHP can be well utilized as DLC-enabled loads for frequency regulation while ensuring residents' comfort and long-term device performance.

This paper discusses a face image abstraction method by using SIFT features and Ford-Fulkerson algorithm. Ford-Fulkerson algorithm is used to compute the maximum flow in a flow network drawn on SIFT features extracted from a face image. The idea is to obtain an augmenting path which is a path from the source vertex to destination vertex with the available capacities on all edges along a set of paths and flow is calculated along one of these paths. The process is repeated until it is obtained more paths with the available capacities. At the initial stage, face image is characterized by SIFT (Scale Invariant Feature Transform) features and the keypoints descriptor information is taken as features set for further processing. Keypoints descriptor is used to generate several face representations by using a series of matrix operations which are further used to determine a Directed Acyclic Graph (DAG). The resultant directed graph contains sparse and distinctive face characteristics of a subject from which the face image is captured. We then apply the Ford-Fulkerson algorithm on the directed graph to maintain the capacity constraints, skew symmetry and flow conservation to obtain an augmenting path with available capacities (relation between SIFT points). Finally, we obtain a mathematical representation of a face image and this representation is further encoded to be used as a set of distinctive features for matching. The time complexity of the proposed face abstraction algorithm is found to be O(VE 2 ) where V is the set of vertices and E is the set of edges in a directed graph.

White Rabbit (WR) is an Ethernet-based technology that provides data transfer and synchronization in sensor networks with a sub-nanosecond accuracy and a precision of 20 picoseconds. WR networks are composed of switches and nodes forming a tree hierarchical model where end-nodes are connected to different sensors and actuators whilst WR switches are intermediate elements that are used as time reference distributors through the whole network. WR networks access requires the utilization of specialized timing interfaces. To allow their utilization on commodity hardware, we have developed a White Rabbit Network Interface Card (WR-NIC). The WR-NIC is composed of a WR node provided with the proper gateware that can be plugged in a PCIe slot of a conventional computer and can be controlled by a Linux kernel driver as a standard network interface card (NIC). The same node allows a stand-alone operation mode thanks to the utilization of a C/C++ library called CALoE, which provides the device with remotely control features. This work describes the different WR-NIC features and all its elements.

The online evolution and learning of fuzzy systems is highly important when dealing with changing environments over time. This capability is especially relevant in the field of control, due to the special characteristics of control problems. In this field, techniques capable of developing controllers with a minimum amount of prior knowledge about the plants to be controlled are desired. Furthermore, these controllers should provide a reduced number of interpretable rules. This paper presents a new Online Self-Evolving Neuro Fuzzy controller based on the Taylor Series Neuro Fuzzy (TaSe-NF) model. Under the assumption of no prior knowledge about the differential equations that define the plant to be controlled, this methodology is capable of incrementally evolving the structure of the controller and adapting its parameters online, while controlling the plant. The new methodology uses a scattered distribution of the fuzzy rules, thereby reducing the number of rules in the fuzzy controller. Moreover, the use of the TaSe-NF model to represent the antecedents of the rules enhances the interpretability of the obtained rules. The proposed evolving fuzzy controller is composed of two main blocks: On the one hand, the online local learning of the rule consequents tackles the task of providing a proper control at the present moment. On the other hand, a structure self-evolution method analyzes the error surface to determine which cluster/rule suffers the worst performance and therefore, needs to be further split. Simulation results are presented to illustrate the capabilities of this new online self-evolving controller. © 2012 Elsevier Inc. All rights reserved.

KM3NeT will be a network of deep-sea neutrino telescopes in the Mediterranean Sea. The KM3NeT/ARCA detector, to be installed at the Capo Passero site (Italy), is optimised for the detection of high-energy neutrinos of cosmic origin. Thanks to its geographical location on the Northern hemisphere, KM3NeT/ARCA can observe upgoing neutrinos from most of the Galactic Plane, including the Galactic Centre. Given its effective area and excellent pointing resolution, KM3NeT/ARCA will measure or significantly constrain the neutrino flux from potential astrophysical neutrino sources. At the same time, it will test flux predictions based on gamma-ray measurements and the assumption that the gamma-ray flux is of hadronic origin. Assuming this scenario, discovery potentials and sensitivities for a selected list of Galactic sources and to generic point sources with an E−2 spectrum are presented. These spectra are assumed to be time independent. The results indicate that an observation with 3σ significance is possible in about six years of operation for the most intense sources, such as Supernovae Remnants RXJ1713.7-3946 and Vela Jr. If no signal will be found during this time, the fraction of the gamma-ray flux coming from hadronic processes can be constrained to be below 50% for these two objects.

Feature selection is required in many applications that involve high dimensional model building or classification problems. Many bioinformatics applications belong to this type. Recently, some approaches for supervised and unsupervised feature selection as a multi-objective optimization problem have been proposed. As the performance of unsupervised classification is evaluated through the quality of the obtained groups or clusters in the data set to be classified, it is difficult to define a suitable objective function that drives the selection of the features. Thus, several evaluation measures, and thus multi-objective clustering characterization, could provide a suitable set of features for unsupervised classification. In this paper, we consider the parallel implementation of a multi-objective feature selection that makes it possible to apply it to complex classification problems such as those having many features to select, and specifically high-dimensional data sets with much more features than data items. In this paper, we propose master-worker implementations of two different parallel evolutionary models, the parallel computation of the cost functions for the individuals in the population, and the parallel execution of evolutionary multi-objective procedures on subpopulations. The experiments accomplished on different benchmarks, including some related with feature selection in classification of EEG (Electroencephalogram) signals for BCI (Brain computer Interface) applications, show the benefits of parallel processing not only for decreasing the running time, but also for improving the solution quality.

This paper presents an automated code generation and validation, verification approach to convert model based developments into IEC 61131-3 conform function blocks. IEC 61131-3 programming languages are supported by PLC manufacturers and software environment developers and provide the possibility that novel and intelligent algorithms can be directly operated on industrial accepted systems. Railway and transportation also receive drastic changes from purely hardware based systems to microcontroller + software driven systems. However, the conversion has to follow certain steps to ensure that the adaptation is done correctly and functionality is not alternated, added or deleted. Concepts suggested by different international standards such as the IEC 61508 can help to derive a tool chain to verify the generated code. © IFAC.

This paper describes the use of ant colony models for photographic rendering, that is, for the depiction or interpretation of photographic images. A description of a previously proposed ant-based edge detection method called pherographia is given in order to contextualize this paper's proposal. Then, the application of the KANTS algorithm to photo-rendering is introduced. KANTS is ant-based clustering algorithm described by a set of equations that model the local behavior of simple units (ants). These units represent data samples. When moving on a heterogeneous 2-dimensional lattice of vectors, global behavior emerges from the local interaction between the ants, which self-organize into clusters. In this paper, a data set consists of the RGB values of a digital (or digitalized) photograph. Two different approaches for the initialization of the environment are tested, each one resulting in radically different output images: when the environment is initialized with the RGB values of the same image that is used to generate the data set, the final result is very similar to the original photo;a random initialization of the environment leads to an abstract interpretation of the photo. The results are contextualized within previous swarm artworks by the authors. © 2013 IEEE.
