Abstract

Debido al alto coste de realizar pruebas utilizando despliegues reales a la hora de trabajar con Redes Vehiculares, una de las técnicas más utilizadas es la simulación. Esta simulación, como es de suponer, debe contemplar todo tipo de detalles, siempre dirigidos a incrementar el nivel de realismo de dichas simulaciones, así como la precisión de los resultados obtenidos. En el presente seminario, se presentarán los detalles más importantes a tener en cuenta a la hora de realizar simulaciones, se dará un tutorial del simulador OMNeT++ y de sus modelos para simulación de entornos vehiculares, y finalmente se presentará la herramienta VACAMOBIL, que permite la simulación de movilidad realista de vehículos en entornos metropolitanos en base a parámetros predefinidos.

Abstract: The computer vision and image processing fields have witnessed remarkable advances on a wide range of problems, most of them with direct impact on the robotics field. Regardless of the advances, they assumed that the light rays travel through the medium without any alteration. However, the medium can change the intensity and the direction of the light rays being named participating medium. Among them, the most important in terms of robotics application and discussed here are the turbid water and haze/fog. This talk presents the adopted approaches to reduce the effects generated by the medium. They are based on a physical light attenuation model which is used to enhance the quality of visual features of the images and the applicability of traditional computer vision techniques for these images. Furthermore, the talk shows the recent works developed in NAUTEC/FURG on robotics and computer vision.

Title: “Federation Management (Cloud and Otherwise) Using the OpenStack Mitaka Release”

Abstract:

Federation is a fundamental goal of many distributed systems, including clouds, and more accurately, services. As a possible corollary to Metcalfes Law, the value of a cloud is proportional to the square of the number of users and services connected. A key concept to grasp is that in a service architecture, federation can be done at any level in the system stack. A cloud is simply a set of services, and a SaaS cloud can include any arbitrary, application-level services. As such, cloud federation is a special case of general service federation.

This talk establishes the basic requirements and properties for federation and reviews relevant, existing standards. We review the NIST Cloud Deployment Models to extract the more fundamental properties of _trust boundaries_ and _trust topologies_. This allows us to describe a set of Federation Deployment Models.

Armed with this clear understanding of the federation design space, we describe our current work in building a prototype, KeyVOMS, a Keystone-based Virtual Organization Management System. KeyVOMS uses the Virtual Organization concept (originating in the grid computing era) for managing federations, and is based on a re-purposed OpenStack Keystone v3 server. Our current implementation is a simple, centralized, third-party server, based on the Havana release. We are currently implementing a Peer-to-Peer version based on the Mitaka release that will leverage the latest Keystone capabilities. We conclude by reviewing related work and future work.

Abstract:

The presentation contains a brief overview of systems and computer engineering research and laboratories at Technical University of Iasi: sound of vision project [1], autonomous mobile robots - sample gathering project [2], and other small projects. This is followed by my research on holonic manufacturing systems [3] and [4]. Here, it is discussed about connecting the implementation of manufacturing systems with their behavioral models that can be obtained by the means of colored Petri nets [5]. Distributed algorithms are between the topical approaches used in manufacturing control architectures. Their validation and evaluation techniques are challengeable due the non-deterministic execution and the partial knowledge of each entity. The development phase can hide several issues; for example, to reproduce a failure or worse execution based on the simulation data may be difficult. With respect to this, one possibility is to develop a model-prototype enclosing some basic characteristics: simple and understandable, shareable, modifiable, catching the partial/entire system’s behavior, allowing space state analysis and simulations. Such a model can be built up through colored Petri nets, using the CPN Tool [5]. The considered example regards the model for three distributed constraint satisfaction algorithms [6]: synchronous backtracking, asynchronous backtracking and weak-commitment search. Following this approach, other distributed protocols can be designed and validated, too.

Abstract:

In this talk, I will first give an overview of my research in healthcare in France and in China since over 10 years. I will then focus on stochastic models for planning and dynamic scheduling of operating rooms.

I first present stochastic models for Operating Room (OR) planning with two classes of patients: elective surgery and emergency surgery. Elective cases can be planned starting from an earliest date with a patient related cost depending on the surgery date. Emergency cases arrive randomly and have to be performed in the day of arrival. The planning problem consists in assign elective cases to different periods over a planning horizon in order to minimize the sum of elective patient related costs and overtime costs of operating rooms. We first propose a basic stochastic mathematical programming model and a Monte Carlo optimization method combining the Monte Carlo simulation and Mixed Integer Programming. The convergence to real optimal and properties of the convergence rate as the computation budget increase are established. We then extended the basic OR planning model to include important factors such as patient to OR assignment, random operating times and overtime capacity constraints. The Monte Carlo optimization method can be extended to solve the more general case but the computation time quickly goes beyond acceptable limit. We then propose a column generation approach that is able to provide efficient solutions for problems of realistic size with duality gap of less than 1%.

I will then address the daily surgery scheduling in a multi-OR setting with random surgery durations. We first address the dynamic assignment of a given set of surgeries with planned surgeon arrival times also called appointment times. Surgeries are assigned dynamically to ORs. The goal is to minimize the total expected cost incurred by surgeon waiting and OR idling/overtime. We first formulate the problem as a multi-stage stochastic programming model. An efficient algorithm is then proposed by combining a two-stage stochastic programming approximation and some look-ahead strategies. A perfect information-based lower bound of the optimal expected cost is given to evaluate the optimality gap of the dynamic assignment strategy. Numerical results show that the dynamic scheduling and optimization with the proposed approach significantly improve the performance of usual static scheduling and First Come First Serve (FCFS) strategies.

We then address the optimization of surgeon appointment times for a sequence of surgeries. Surgeries are assigned to ORs dynamically on a FCFS basis. It materially differs from past literature in the sense that dynamic assignments are proactively anticipated in the determination of appointment times. A discrete-event framework is proposed to model the execution of the surgery schedule and to evaluate the sample path gradient of a total cost incurred by surgeon waiting, OR idling and OR overtime. The sample path cost function is shown to be unimodal, Lipchitz continuous and differentiable w.p.1 and the expected cost function continuously differentiable. A stochastic approximation algorithm based on unbiased gradient estimators is proposed and extensive numerical experiments suggest that it converges to a global optimum. A series of numerical experiments are performed to show the significant benefits of Multi-OR and properties of the optimal solution with respect to various system parameters such as cost structure and numbers of surgeries and ORs.

The last part of this talk is devoted to the daily overtime management to provide OR-teams with different degrees of guarantee of on-time end of the day. This problem is modelled as two stochastic bin packing problems with chance constraints: a stochastic programming model and a robust formulation with moment information. We present a tailored branch-and-price approach based on a column generation reformulation for which CVaR and probabilistic sets are employed to speed-up the resolution of the pricing problems. For the distributionally robust formulation the worst-case distribution is shown to be a three-point distribution, analytical expression of the worst chance probability derived and simple mixed integer linear program model obtained. We implement a series of real-data-based numerical experiments to show that the benefits of optimal allocation and illustrate the value of robust solution.

Resumenbr Debido al desarrollo tecnológico, el coche inteligente se está convirtiendo en uno de los protagonistas indiscutibles del siglo XXI. En los últimos años han sido numerosos los avances que vienen siendo introducidos paulatinamente en nuestros vehiculos. Sin embargo, todavía existen dos factores clave en el vehículo del futuro, por un lado el combustible que dichos vehículos consumirán, siendo el vehículo eléctrico uno de los más prometedores, y por otro lado los sistemas de comunicación entre vehículos, que en un futuro a medio plazo podrán permitir la existencia del vehículo autónomo y la conducción cooperativa. Por otra parte, uno de los principales hándicaps de este sector es la lenta renovación del parque móvil existente, por lo que se hace necesaria la incorporación de tecnologías intermedias que nos permitan acelerar la introducción progresiva de las nuevas propuestas y servicios.

Resumen:br Reliability assessment has been traditionally dominated by the Fault Trees vs Markov Chains discussion. Between this two extremes, Bayesian Networks are a valid alternative option since a greater modeling power than the Fault Trees and greater solution efficiency than Markov Chains. This talk introduces such language showing how it can be used in the modeling of reliability, safety and security of complex and critical systems. The talk also summarizes some experiences of framing the BN formalism into model-driven approaches.

Abstract:br La aparición reciente de cámaras de profundidad compactas y de bajo coste ha supuesto un revulsivo en la capacidad sensorial de los robots autónomos, hasta el punto que estamos asistiendo a avances que hacen presagiar a muy corto plazo aplicaciones robóticas que hasta hace pocos años se pensaban lejanas en el tiempo. El aprovechamiento en robótica de estas nuevas tecnologías (cámaras TOF y RGB¬D, fundamentalmente) exige métodos y algoritmos específicos que procesen eficientemente la ingente cantidad de datos suministrados y, en última instancia, proporcionen al robot información del entorno útil para navegar, tomar decisiones, interaccionar con personas, etc. En esta charla, el prof. González¬Jiménez revisa las aportaciones del grupo MAPIR¬UMA (http://mapir.isa.uma.es) en este campo.

Abstract:br This talk addresses the challenge of localizing mobile devices inside large building structures with a special focus on visual localization. In visual indoor localization, the position and orientation of a mobile device are recovered using the images captured by its built-in video camera. Given these images, location information can be obtained by comparing the captured images with a data base of geo-tagged reference images of the environment using concepts from the field of content-based image retrieval. Flexible and cost-efficient acquisition of this reference image data base is a key technology in this context. Hence, a significant part of the talk will be devoted to the acquisition of this data base for a previously unknown environment. Once this reference data is available, then pose estimation needs to be performed with minimum latency, and hence the talk will also cover concepts for minimizing the client server communication for visual localization. In order to improve the robustness and accuracy of the indoor localization process, the visual information needs to be fused with other sources of information, such as pedometer, WiFi, magnetometer, etc. To this end we present a graph-based fusion algorithm which substantially reduces the complexity of a particle filter-based sensor fusion approach and makes it applicable on standard mobile devices. The talk will end with a demonstration of our prototype visual indoor localization and navigation system and an overview of the remaining challenges on the way to GPS-free indoor navigation.br br

Abstract:br I will describe an approach for synthesizing time-lapse videos of popular landmarks from large community photo collections. The approach is completely automated and leverages the vast quantity of photos available online. First, we cluster 86 million photos into landmarks and popular viewpoints. Then, we sort the photos by date and warp each photo onto a common viewpoint. Finally, we stabilize the appearance of the sequence to compensate for lighting effects and minimize flicker. The approach is also extended to moving camera paths where a virtual camera moves both in space and time, creating time-lapse videos with compelling parallax effects. Our resulting time-lapses show diverse changes in the worlds most popular sites, like glaciers shrinking, skyscrapers being constructed, and waterfalls changing course p (see this a href=https://www.youtube.com/watch?v=wptzVm0tngc video /a ).

Titulo Conferencia: Proyecto Romol: Runtime Aware Architecturesbr Fecha: Lunes 1 de Junio, 18hbr Lugar: Aula A03, Edificio Ada Byron, Campus Rio Ebro

Abstract:br In the last years the traditional ways to keep the increase of hardware performance to the rate predicted by the Moores Law vanished. When uni-cores were the norm, hardware design was decoupled from the software stack thanks to a well defined Instruction Set Architecture (ISA). This simple interface allowed developing applications without worrying too much about the underlying hardware, while computer architects proposed techniques to aggressively exploit Instruction-Level Parallelism (ILP) in superscalar processors. Current multi-cores are designed as simple symmetric multiprocessors on a chip. While these designs are able to compensate the clock frequency stagnation, they face multiple problems in terms of power consumption, programmability, resilience or memory. The solution is to give more responsibility to the runtime system and to let it tightly collaborate with the hardware. The runtime has to drive the design of future multi-cores architectures. In this talk, we introduce an approach towards a Runtime-Aware Architecture (RAA), a massively parallel architecture designed from the runtimes perspective.

Abstract: The challenges of controlling dynamic systems with multiple objectives are related to and furthermore include problems in multi-player dynamic games, multiobjective optimization, and decentralized control and estimation. The additional complexity is introduced through nonlinear dynamic models with possible delays and perturbations as well as various state, input and communication constraints. In this talk we will present a number of results related to control and coordination of multi-agent systems pursuing multiple objectives. To illustrate these results some particular examples of controlling multiple agents pursuing multiple objectives such as guaranteed capture or evasion, collision avoidance, coverage control, proximity, and tracking, will be presented.

Abstract:br This talk will present insights gained from the operation of an Australia-wide benthic observing program designed to deliver precisely navigated, time series imagery of the seafloor using Autonomous Underwater Vehicles (AUVs). This initiative makes extensive use of AUVs to collect high-resolution stereo imagery, multibeam sonar and water column measurements on an annual or semi-annual basis at sites around Australia, spanning the full latitudinal range of the continent from tropical reefs in the north to temperate regions in the south. In this talk, we will provide an update on the status of this observing program and outline examples of research that has been facilitated by this work in the areas of environmental monitoring, archaeology and geosciences. Examples of these outcomes highlight our ability to revisit survey sites across multiple years and illustrate how automated tools can be used to identify patterns within the large volumes of data being collected.

In this talk, I will present a new Machine Learning-based approach to detecting local image features, with application to contour detection in natural images, but also biomedical and aerial images, and to feature point extraction under drastic weather and lighting changes. I will then show that it is also possible to learn efficient object description based on low-level features for scalable 3D object detection.

Título: Aprendizaje directo y aplicaciones en percepciónbr En los últimos años se ha desarrollado una aproximación dinámica al estudio del aprendizaje perceptivo y perceptivo-motor. Este marco teórico se denomina teoría del aprendizaje directo. Esta aproximación describe el aprendizaje como un movimiento lento y continuo en un espacio de pocas dimensiones, habitualmente denominado espacio de información-calibración. Cada punto de un espacio de información-calibración representa una tupla de una variable informacional junto a una calibración específica. El aprendizaje es definido, por tanto, como un cambio en la variable informacional que es operativa en un momento dado y un cambio en la forma en que dicha variable es usada. El elemento central de esta teoría es que el aprendizaje mismo -el movimiento en ese espacio- es visto como un proceso guiado informacionalmente. En la presente charla se introduce la teoría de aprendizaje directo y se considera algunas posibles aplicaciones.

Abstract: There is a current demand for more dependable and autonomous technology. To guarantee mission-level resilience, the limited adaptivity of standard control techniques is not enough, there is a need for actual self-engineering by the system themselves at runtime. For that purpose we propose to leverage the engineering models and biologically inspired cognitive capabilities to build functional metacontrol loops capable of self-awareness and self-adaptation. Our approach goes beyond the customary applications in mobile robotics into the deep waters of autonomous systems engineering. A necessary technology for the machines of the future.

Abstract: Even relatively simple animals exhibit a remarkable combination of flexibility and robustness in their behavior. My research aims to address this challenge by constructing and analyzing empirically-grounded models of brain-body-environment systems. In the talk, I will argue that the nematode worm Caenorhabditis elegans is a convenient initial target for such integrated brain-body-environment modeling of a complete animal. My approach uses artificial evolution to explore the space of unknown electrophysiological parameters of the nervous system necessary to generate organism-like behavior.

Abstract: It is becoming increasingly evident that the temporal variability in behavior constitutes a rich source of information about its coordinative basis. In this presentation I will emphasize the fractal nature of coordination dynamics underlying human performance in the motor domain and beyond. Attention will be given to techniques for detecting and quantifying the temporal structure of behavior and to the implications of this structure for coordination dynamics.

Abstract: How does our brain work? How does it explain the way we behave and how we experience our world? These general questions are approached from the point of view of cognitive neuroscience, a research field which merges cognitive psychology and neuroscience. In this talk I will introduce the general concept of selective neuronal communication which lies at the center of functional network interactions in the so-called brainweb. In animal and human neural systems, selective communication is achieved through the mechanism of neuronal oscillatory synchronization. I will review various human and animal intracranial recording studies which focus on neuronal oscillatory synchronization.

Resumen:br In the last two years, we have heard a lot of news about Micro Aerial Vehicles (MAVs), in the form of small quadrotors. Quadrotors have numerous advantages over ground vehicles: they can easily reach environments that no human can access and have more agility and navigational capabilities than ground vehicles. Unfortunately, their dynamics makes them extremely difficult to control and this is particularly true in absence of external positioning systems, such as GPS.. In this talk, I will give an overview of my research activities on visual navigation of MAVs, from slow navigation (using standard frame-based cameras) to agile flight (using event-based cameras).br pa href=http://rpg.ifi.uzh.ch Robotics and Perception Group of University of Zurich/a./p pa href=https://plus.google.com/+DavideScaramuzza/posts Google + Davide Scaramuzza/a./p Bio:br Davide Scaramuzza is Assistant Professor of Robotics at the University of Zurich and Adjunct Faculty at ETH Zurich.

We are concerned with controllability and observability of timed continuous Petri nets (TCPN) under the infinite server semantics. In particular, we deal with structural and generic controllability (i.e., controllability for all values of the firing rates, and for almost all values of those parameters, respectively). Using ideas developed for linear structured systems theory, the concept of generic controllability is employed to characterize controllability for TCPN in terms of the structure of the Petri net graph. Joins, conflicts, forks and attributions are used to explain how control signals are transmitted or blocked through the net. Based on the net graph, the obtained results are viewed as the dual of the previous obtained for structural and generic observability in TCPN. Clear relationships are stated using the duality concept on Petri net graphs.

Lugar: Seminario del Departamento.br Día: 3 miércoles de Diciembre.br Hora: 13h.br Ponente: Manuel Navarro.

The dynamic behavior of TCPN under the infinite server semantics will be considered. In particular, we study the change of the throughput in steady state due to the variation of a firing rate. Jumps in this value (equivalently in the steady state marking) are considered as bifurcations. They occur in nets in which the equilibrium marking of a region goes from being stable to unstable. In _equal-conflict_ nets the bifurcation may occur depending on the firing rates of transitions in conflicts; if transitions are also joins, the steady state marking lies in the boundary between regions.br We show that in consistent and conservative _choice-free_ Petri nets the change in the steady state throughput is continuous. This kind of result can be extended to equal-conflict nets when we vary the firing rates of transitions which are persistent. So, the throughput in steady state is continuous, moreover also monotone for these classes of nets.br Similarly, the variation of the initial marking is considered. There are relationships between the observed behavior of the throughput due to the change of a firing rate and the variation of components of the initial marking. Bifurcations are critical for the performance of the net system, thus very interesting in order to control them

Green Computing meets Big Data Iván Rodero, Rutgers Discovery Informatics Institute, The State University of New Jersey Lunes, 30 de Junio de 2014, 10:30, Seminario DIIS - Edificio Ada Byron

As computational- and data-enabled scientific applications target extreme scales, energy/power-related challenges are becoming dominating concerns. As a result, it is critical to explore emerging architectures such as ongoing many-core processors and deep memory hierarchies as well as applications from an energy perspective, and investigate associated overheads and tradeoffs. For example, energy/power-efficiency has to be addressed in combination with the quality of the solution, performance, resiliency, and other objectives. At the same time, the deluge of big data does not come only from scientific instruments and simulations, but also from sensor networks and other sources such as web crawling and social networks. Being able to transform this data into insights also presents energy/power-related challenges that need to be addressed in the context of different data analytics frameworks.

In this talk, I will explore these issues and will describe selected ongoing research efforts directed towards the scalability and efficiency of the next generation computing systems, including: in-situ data analytics for combustion simulations and co-processing at extreme scales; a framework for exascale co-design; energy/power-efficient data management for big data analytics on systems with deep memory hierarchies and accelerators; and other relevant efforts focused on understanding the cost of data movement and computation scheduling.

Iván Rodero is Assistant Research Professor in the department of the Electrical and Computer Engineering, at the Rutgers Discovery Informatics Institute and at the NSF Cloud and Autonomic Computing Center at Rutgers, The State University of New Jersey. He received an integrated BS and MS degree in Computer Engineering in 2004 and a PhD degree in 2009 from Technical University of Catalonia, Spain. Before joining Rutgers, he was permanent researcher at Barcelona Supercomputing Center. His research interests fall in the broad area of parallel and distributed computing and include high performance computing, data management, energy efficiency, and autonomic and cloud computing. Rodero’s current research activities are in the intersection of green computing and scientific (big) data management and analytics, and have been funded by the National Science Foundation and the U.S. Department of Energy. His research also comprises distributed computing systems, including cloud computing mechanisms and abstractions, federation of large-scale computing systems and cyber-security.

Abstract. The talk informally presents some techniques for solving problems with immediate applications to mobile robots. The common point of these techniques is to develop a discrete event system that models the environment and/or the robot movements. Based on the mission requirements and on the problem assumptions, we investigate different types of discrete-event models, ranging from automata/graphs to Petri nets. Feasible solutions on the finite state models are found by involving various tools, such as translations to typical optimization problems or resource allocation techniques. Most of the developed frameworks are applicable for a whole team of cooperating robots. The determined discrete solutions yield sequences of simple decisions and routines that should be executed by the mobile robots such that the given task is accomplished.

Speakers short biography. M. Kloetzer received B.S. (2002) and M.Sc. (2003) degrees in Computer Science from the Technical University of Iasi, Romania, and Ph.D. (2008) in Systems Engineering from Boston University, Boston, MA, USA. He is currently an associate professor at the Technical University of Iasi, Romania. In May-June 2014 he is a guest researcher at the University of Zaragoza, within a mobility grant for guest researches at Campus Iberus. His research interests include planning algorithms for mobile robots based on discrete event systems and high-level specifications.

The biotechnology industry has grown in an unprecedented way in recent years owing to advances in fields like molecular modelling, systems biology, disease characterization, or pharmaceutical discovery. Systems biology aims to achieve a quantitative phenotypic description of a biological system. Advances in this particular field have been incorporated in fundamental and applied research. Efforts were focused mainly on the high-throughput analysis of cell parts and genome-scale metabolic modelling. The utilization of such approaches in biotechnology aims to achieve a systems level understanding of the microorganisms that are suitable models in biomedical research or are efficient cell factories for the production of high value commodities. Currently, vast amounts of data are being produced with the new experimental technologies, producing a bottleneck in their analysis. Improved bioinformatics tools and models are currently being developed and employed to capitalize the data on becoming accessible in biotechnology applications. This talk will focus on currently faced challenges in systems biology and several initiatives taken towards addressing several different problems in the topic.

Pedestrian detection is of paramount interest for many applications. Most promising detectors rely on classifiers trained with annotated samples. However, the annotation step is a human intensive and subjective task worth to be minimized. By using virtual worlds we can automatically obtain precise and rich annotations. Thus, we face the question: can a pedestrian appearance model learnt in realistic virtual worlds work successfully for pedestrian detection in real world images? Conducted experiments show that virtual-world based training can provide excellent testing accuracy in some real-world datasets, but it also appears the dataset shift problem in many others. Accordingly, during the last years we have explored different domain adaptation ideas for several state-of-the-art pedestrian detection approaches. In this talk, we review this work. Therefore, we will report adaptation results for different features as HOG, LBP, Haar and EOH, different pedestrian models as the Holistic-SVM/AdaBoost and Deformable Part-Based Models (DPM), as well as different strategies as supervised/unsupervised and batch/incremental. Overall, we will see that we have been able to actually adapt virtual and real worlds.
