Automated wordlength optimization framework for multi-source statistical interval-based analysis of nonlinear systems with control-flow structures

El uso de aritmética de punto fijo es una opción de diseño muy extendida en sistemas con fuertes restricciones de área, consumo o rendimiento. Para producir implementaciones donde los costes se minimicen sin impactar negativamente en la precisión de los resultados debemos llevar a cabo una asignación cuidadosa de anchuras de palabra. Encontrar la combinación óptima de anchuras de palabra en coma fija para un sistema dado es un problema combinatorio NP-hard al que los diseñadores dedican entre el 25 y el 50 % del ciclo de diseño. Las plataformas hardware reconfigurables, como son las FPGAs, también se benefician de las ventajas que ofrece la aritmética de coma fija, ya que éstas compensan las frecuencias de reloj más bajas y el uso más ineficiente del hardware que hacen estas plataformas respecto a los ASICs. A medida que las FPGAs se popularizan para su uso en computación científica los diseños aumentan de tamaño y complejidad hasta llegar al punto en que no pueden ser manejados eficientemente por las técnicas actuales de modelado de señal y ruido de cuantificación y de optimización de anchura de palabra. En esta Tesis Doctoral exploramos distintos aspectos del problema de la cuantificación y presentamos nuevas metodologías para cada uno de ellos: Las técnicas basadas en extensiones de intervalos han permitido obtener modelos de propagación de señal y ruido de cuantificación muy precisos en sistemas con operaciones no lineales. Nosotros llevamos esta aproximación un paso más allá introduciendo elementos de Multi-Element Generalized Polynomial Chaos (ME-gPC) y combinándolos con una técnica moderna basada en Modified Affine Arithmetic (MAA) estadístico para así modelar sistemas que contienen estructuras de control de flujo. Nuestra metodología genera los distintos caminos de ejecución automáticamente, determina las regiones del dominio de entrada que ejercitarán cada uno de ellos y extrae los momentos estadísticos del sistema a partir de dichas soluciones parciales. Utilizamos esta técnica para estimar tanto el rango dinámico como el ruido de redondeo en sistemas con las ya mencionadas estructuras de control de flujo y mostramos la precisión de nuestra aproximación, que en determinados casos de uso con operadores no lineales llega a tener tan solo una desviación del 0.04% con respecto a los valores de referencia obtenidos mediante simulación. Un inconveniente conocido de las técnicas basadas en extensiones de intervalos es la explosión combinacional de términos a medida que el tamaño de los sistemas a estudiar crece, lo cual conlleva problemas de escalabilidad. Para afrontar este problema presen tamos una técnica de inyección de ruidos agrupados que hace grupos con las señales del sistema, introduce las fuentes de ruido para cada uno de los grupos por separado y finalmente combina los resultados de cada uno de ellos. De esta forma, el número de fuentes de ruido queda controlado en cada momento y, debido a ello, la explosión combinatoria se minimiza. También presentamos un algoritmo de particionado multi-vía destinado a minimizar la desviación de los resultados a causa de la pérdida de correlación entre términos de ruido con el objetivo de mantener los resultados tan precisos como sea posible. La presente Tesis Doctoral también aborda el desarrollo de metodologías de optimización de anchura de palabra basadas en simulaciones de Monte-Cario que se ejecuten en tiempos razonables. Para ello presentamos dos nuevas técnicas que exploran la reducción del tiempo de ejecución desde distintos ángulos: En primer lugar, el método interpolativo aplica un interpolador sencillo pero preciso para estimar la sensibilidad de cada señal, y que es usado después durante la etapa de optimización. En segundo lugar, el método incremental gira en torno al hecho de que, aunque es estrictamente necesario mantener un intervalo de confianza dado para los resultados finales de nuestra búsqueda, podemos emplear niveles de confianza más relajados, lo cual deriva en un menor número de pruebas por simulación, en las etapas iniciales de la búsqueda, cuando todavía estamos lejos de las soluciones optimizadas. Mediante estas dos aproximaciones demostramos que podemos acelerar el tiempo de ejecución de los algoritmos clásicos de búsqueda voraz en factores de hasta x240 para problemas de tamaño pequeño/mediano. Finalmente, este libro presenta HOPLITE, una infraestructura de cuantificación automatizada, flexible y modular que incluye la implementación de las técnicas anteriores y se proporciona de forma pública. Su objetivo es ofrecer a desabolladores e investigadores un entorno común para prototipar y verificar nuevas metodologías de cuantificación de forma sencilla. Describimos el flujo de trabajo, justificamos las decisiones de diseño tomadas, explicamos su API pública y hacemos una demostración paso a paso de su funcionamiento. Además mostramos, a través de un ejemplo sencillo, la forma en que conectar nuevas extensiones a la herramienta con las interfaces ya existentes para poder así expandir y mejorar las capacidades de HOPLITE. ABSTRACT Using fixed-point arithmetic is one of the most common design choices for systems where area, power or throughput are heavily constrained. In order to produce implementations where the cost is minimized without negatively impacting the accuracy of the results, a careful assignment of word-lengths is required. The problem of finding the optimal combination of fixed-point word-lengths for a given system is a combinatorial NP-hard problem to which developers devote between 25 and 50% of the design-cycle time. Reconfigurable hardware platforms such as FPGAs also benefit of the advantages of fixed-point arithmetic, as it compensates for the slower clock frequencies and less efficient area utilization of the hardware platform with respect to ASICs. As FPGAs become commonly used for scientific computation, designs constantly grow larger and more complex, up to the point where they cannot be handled efficiently by current signal and quantization noise modelling and word-length optimization methodologies. In this Ph.D. Thesis we explore different aspects of the quantization problem and we present new methodologies for each of them: The techniques based on extensions of intervals have allowed to obtain accurate models of the signal and quantization noise propagation in systems with non-linear operations. We take this approach a step further by introducing elements of MultiElement Generalized Polynomial Chaos (ME-gPC) and combining them with an stateof- the-art Statistical Modified Affine Arithmetic (MAA) based methodology in order to model systems that contain control-flow structures. Our methodology produces the different execution paths automatically, determines the regions of the input domain that will exercise them, and extracts the system statistical moments from the partial results. We use this technique to estimate both the dynamic range and the round-off noise in systems with the aforementioned control-flow structures. We show the good accuracy of our approach, which in some case studies with non-linear operators shows a 0.04 % deviation respect to the simulation-based reference values. A known drawback of the techniques based on extensions of intervals is the combinatorial explosion of terms as the size of the targeted systems grows, which leads to scalability problems. To address this issue we present a clustered noise injection technique that groups the signals in the system, introduces the noise terms in each group independently and then combines the results at the end. In this way, the number of noise sources in the system at a given time is controlled and, because of this, the combinato rial explosion is minimized. We also present a multi-way partitioning algorithm aimed at minimizing the deviation of the results due to the loss of correlation between noise terms, in order to keep the results as accurate as possible. This Ph.D. Thesis also covers the development of methodologies for word-length optimization based on Monte-Carlo simulations in reasonable times. We do so by presenting two novel techniques that explore the reduction of the execution times approaching the problem in two different ways: First, the interpolative method applies a simple but precise interpolator to estimate the sensitivity of each signal, which is later used to guide the optimization effort. Second, the incremental method revolves on the fact that, although we strictly need to guarantee a certain confidence level in the simulations for the final results of the optimization process, we can do it with more relaxed levels, which in turn implies using a considerably smaller amount of samples, in the initial stages of the process, when we are still far from the optimized solution. Through these two approaches we demonstrate that the execution time of classical greedy techniques can be accelerated by factors of up to ×240 for small/medium sized problems. Finally, this book introduces HOPLITE, an automated, flexible and modular framework for quantization that includes the implementation of the previous techniques and is provided for public access. The aim is to offer a common ground for developers and researches for prototyping and verifying new techniques for system modelling and word-length optimization easily. We describe its work flow, justifying the taken design decisions, explain its public API and we do a step-by-step demonstration of its execution. We also show, through an example, the way new extensions to the flow should be connected to the existing interfaces in order to expand and improve the capabilities of HOPLITE.

Quality of experience of adaptive video streaming: investigation in service parameters and subjective quality assessment methodology

The usage of HTTP adaptive streaming (HAS) has become widely spread in multimedia services. Because it allows the service providers to improve the network resource utilization and user׳s Quality of Experience (QoE). Using this technology, the video playback interruption is reduced since the network and server status in addition to capability of user device, all are taken into account by HAS client to adapt the quality to the current condition. Adaptation can be done using different strategies. In order to provide optimal QoE, the perceptual impact of adaptation strategies from point of view of the user should be studied. However, the time-varying video quality due to the adaptation which usually takes place in a long interval introduces a new type of impairment making the subjective evaluation of adaptive streaming system challenging. The contribution of this paper is two-fold: first, it investigates the testing methodology to evaluate HAS QoE by comparing the subjective experimental outcomes obtained from ACR standardized method and a semi-continuous method developed to evaluate the long sequences. In addition, influence of using audiovisual stimuli to evaluate the video-related impairment is inquired. Second, impact of some of the adaptation technical factors including the quality switching amplitude and chunk size in combination with high range of commercial content type is investigated. The results of this study provide a good insight toward achieving appropriate testing method to evaluate HAS QoE, in addition to designing switching strategies with optimal visual quality.

Location of bioelectricity plants in the Madrid Community based on triticale crop: a multicriteria methodology

This paper presents a work whose objective is, first, to quantify the potential of the triticale biomass existing in each of the agricultural regions in the Madrid Community through a crop simulation model based on regression techniques and multiple correlation. Second, a methodology for defining which area has the best conditions for the installation of electricity plants from biomass has been described and applied. The study used a methodology based on compromise programming in a discrete multicriteria decision method (MDM) context. To make a ranking, the following criteria were taken into account: biomass potential, electric power infrastructure, road networks, protected spaces, and urban nuclei surfaces. The results indicate that, in the case of the Madrid Community, the Campiña region is the most suitable for setting up plants powered by biomass. A minimum of 17,339.9 tons of triticale will be needed to satisfy the requirements of a 2.2 MW power plant. The minimum range of action for obtaining the biomass necessary in Campiña region would be 6.6 km around the municipality of Algete, based on Geographic Information Systems. The total biomass which could be made available in considering this range in this region would be 18,430.68 t.

Methodology for instantaneous average exhaust gas mass flow rate measurement

This paper presents a new methodology for measurement of the instantaneous average exhaust mass flow rate in reciprocating internal combustion engines to be used to determinate real driving emissions on light duty vehicles, as part of a Portable Emission Measurement System (PEMS). Firstly a flow meter, named MIVECO flow meter, was designed based on a Pitot tube adapted to exhaust gases which are characterized by moisture and particle content, rapid changes in flow rate and chemical composition, pulsating and reverse flow at very low engine speed. Then, an off-line methodology was developed to calculate the instantaneous average flow, considering the ?square root error? phenomenon. The paper includes the theoretical fundamentals, the developed flow meter specifications, the calibration tests, the description of the proposed off-line methodology and the results of the validation test carried out in a chassis dynamometer, where the validity of the mass flow meter and the methodology developed are demonstrated.

Calidad ambiental electromagnética : atenuación de las radiaciones electromagnéticas en los espacios habitados

La perspectiva del arquitecto en calidad ambiental, y salud en un contexto sostenible, se amplía al considerar las radiaciones electromagnéticas no ionizantes en el diseño arquitectónico. En ese sentido, además del confort higrotérmico, acústico, lumínico y de la calidad del aire, se podría considerar el confort electromagnético de un lugar. Dado que existe gran controversia en cuales han de ser los límites de exposición a radiaciones electromagnéticas no ionizantes, establezco como punto de referencia los valores límite más restrictivos, que son los recomendados por la norma SBM-2008, desarrollada por el Institut für Baubiologie & Oekologie Neubeuern (IBN)1. Se plantean como hipótesis que podemos modificar el entorno electromagnético con materiales de construcción y geometría; y que determinados trazados geométricos tienen la capacidad de reducir el impacto de los campos electromagnéticos sobre los organismos vivos. El objetivo consiste en demostrar experimentalmente que podemos trabajar sobre la calidad ambiental electromagnética de un espacio, a través de la elección de materiales de construcción y trazados geométricos, intentando demostrar que existe una relación causa - efecto entre ambos. La metodología plantea tres aproximaciones experimentales, cada una con un tipo de radiación electromagnética, pues se pretende abarcar las situaciones que comúnmente se pueden presentar en un entorno habitado, ya sea urbano o rural. La primera aproximación trata sobre las alteraciones del campo geomagnético natural (nT / m) provocadas por los materiales de construcción. Utilizo el geomagnetómetro BPM 2010, para realizar un ensayo con cuatro tipos de materiales de distinta procedencia: origen vegetal muy poco procesado (corcho aglomerado negro) y más procesado (OSB), origen derivado del petróleo (tablero rígido de poliuretano) y de origen mineral metálico (chapa minionda). De la lectura de los datos se observa relación causa-efecto entre los materiales de construcción estudiados y las modificaciones que pueden ejercer sobre el campo magnético de un lugar. A continuación se estudia el entorno de radiación electromagnética artificial a baja frecuencia (3 Hz a 3 kHz) y a alta frecuencia, (800 MHz a 10 GHz) en vivienda y en oficina utilizando unas geometrías concretas: las tarjetas de corrección de radiaciones. Estas tarjetas se ubican en paramentos verticales y horizontales de un espacio sometido a radiación propia de un entorno urbano. Se concluye que en una habitación inciden múltiples variables simultáneas muy difíciles de trabajar por separado y que aparentemente no se pueden identificar cambios significativos en las mediciones con y sin las tarjetas de corrección de radiaciones. A continuación estudio el entorno de radiación electromagnética artificial a baja frecuencia asociada a la red de distribución eléctrica. Para poder ver cómo este entorno electromagnético lo podemos modificar, utilizo las tarjetas de corrección de radiaciones ubicadas en relación directa con organismos vivos, por un lado germinados de semillas de haba mungo sometidas a campos electromagnéticos complejos a alta y baja frecuencia, propios de una oficina; y por otro lado germinados de semillas de haba mungo, sometidas a campos electromagnéticos puros a 50 Hz, sin influencias de radiación a alta frecuencia. Se concluye que se observa relación causa - efecto entre los trazados geométricos estudiados y su capacidad para reducir el impacto de los campos electromagnéticos a altas y bajas frecuencias sobre las semillas de haba mungo. También utilizo las tarjetas de corrección de radiaciones en un ensayo normalizado en el laboratorio de bioelectromagnetismo del Hospital Universitario Ramón y Cajal, con células de neuroblastoma humano. Se concluye que se observa relación causa - efecto entre los trazados geométricos estudiados y su capacidad para reducir el impacto de los campos electromagnéticos de 50 Hz Y 100 μT sobre células de neuroblastoma humano y además disminuyen la velocidad de proliferación celular respecto del grupo de células de control. Finalmente se estudia el entorno de radiación electromagnética artificial a alta frecuencia, asociado a comunicaciones inalámbricas. Para ello realizo simulaciones con el software CST Studio, sobre las tarjetas de corrección de radiaciones a alta frecuencia. A la luz de los datos se observa relación causa - efecto entre el trazado geométrico estudiado y su capacidad para reducir radiaciones electromagnéticas de alta frecuencia. Se comprueba además que, las tarjetas de corrección de radiaciones disminuyen la intensidad de la radiación acercándose a los límites de exposición establecidos por el instituto de la biología de la construcción alemán, que podrían estar señalando los estándares de biocompatibilidad. ABSTRACT The perspective of the architect in environmental quality, and health in a sustainable context is extended to consider non-ionizing electromagnetic radiation in architectural design. In that sense, besides the hygrothermal, acoustic, lighting and air quality comfort, the electromagnetic comfort of an indoor space could be considered. There is still great controversy about which should be the limits of exposure to nonionizing electromagnetic radiation, as a benchmark, the more restrictive limits are considered, by the SBM- 2008 standard, developed by the Institut für Baubiologie & Oekologie Neubeuern (IBN). The hypotheses that arise are the following: the electromagnetic environment can be modified by using certain construction materials and geometry; and certain geometric design have the ability to reduce the impact of electromagnetic fields on living organisms. The aim is to demonstrate experimentally that we can work on electromagnetic environmental quality of a indoor space, by using certain construction materials and geometric design, trying to demonstrate a cause - effect relationship between them. The methodology raises three experimental approaches, each with a type of radiation, it is intend to cover situations commonly may occur in an inhabited environment, whether urban or rural. The first approach discusses the alteration of the natural magnetic field (nT / m) caused by the building materials. Geomagnetometre BPM 2010 is used for conducting a test with four types of materials from different sources: vegetable origin less processing (black agglomerate cork) and vegetable origin more processed (OSB), petroleum origin (rigid polyurethane board) and metallic origin (miniwave plate). It is observed across the data information that exist cause-effect relationship between the construction materials studied and the modifications that they can exercise on the magnetic field of a place. Then I study the environment of artificial electromagnetic radiation at low frequency (3 Hz to 3 kHz) and high frequency (800 MHz to 10 GHz) in housing and office, using some specific geometries: correcting radiation cards. These cards are placed in vertical and horizontal surfaces of an indoor space concerned by radiation. I conclude that an indoor space is affected by multiple simultaneous variables difficult to work separately and apparently it is not possible identify significant changes in measurements with and without correcting radiation cards. Then the artificial electromagnetic environment of low-frequency radiation associated with the electricity distribution network is studied. To see how the electromagnetic environment can be changed, correcting radiation cards are placed directly related to living organisms. On one hand, mung bean seeds subject to complex electromagnetic fields at low and high frequency, typical of an office; and on the other hand mung bean seeds, subjected to pure electromagnetic fields at 50 Hz, no influenced by high frequency radiation. It is observed that exist cause-effect relationship between the geometric design and their ability to reduce the impact of electromagnetic fields at high and low frequencies that arrives on on mung bean seeds. The correcting radiation cards were also used in a standard test in the bioelectromagnetics laboratory of Ramón y Cajal University Hospital, on human neuroblastoma cells. It is observed that exist cause-effect relationship between the geometric design and their ability to reduce the impact of electromagnetic fields at 50 Hz and 100 μT on human neuroblastoma cells and also decrease the rate of cell proliferation compared to the group of cells control. Finally the artificial electromagnetic radiation environment at high frequency associated with wireless communications was studied. Simulations with CST Study software were made to determine the behavior of correcting radiation cards in high-frequency. It is observed across the data information that exist causeeffect relationship between the geometric design and the ability to reduce the levels of high-frequency electromagnetic radiation. It also checks that radiation correcting cards decrease the intensity of radiation approaching exposure limits established by Institut für Baubiologie & Oekologie Neubeuern (IBN), which could be signaling biocompatibility standards.

Interleaved concatenated codes: New perspectives on approaching the Shannon limit

The last few years have witnessed a significant decrease in the gap between the Shannon channel capacity limit and what is practically achievable. Progress has resulted from novel extensions of previously known coding techniques involving interleaved concatenated codes. A considerable body of simulation results is now available, supported by an important but limited theoretical basis. This paper presents a computational technique which further ties simulation results to the known theory and reveals a considerable reduction in the complexity required to approach the Shannon limit.

Protein quantification from complex protein mixtures using a proteomics methodology with single-cell resolution

We have developed an extremely sensitive technique, termed immuno-detection amplified by T7 RNA polymerase (IDAT) that is capable of monitoring proteins, lipids, and metabolites and their modifications at the single-cell level. A double-stranded oligonucleotide containing the T7 promoter is conjugated to an antibody (Ab), and then T7 RNA polymerase is used to amplify RNA from the double-stranded oligonucleotides coupled to the Ab in the Ab-antigen complex. By using this technique, we are able to detect the p185her2/neu receptor from the crude lysate of T6–17 cells at 10−13 dilution, which is 109-fold more sensitive than the conventional ELISA method. Single-chain Fv fragments or complementarity determining region peptides of the Ab also can be substituted for the Ab in IDAT. In a modified protocol, the oligonucleotide has been coupled to an Ab against a common epitope to create a universal detector species. With the linear amplification ability of T7 RNA polymerase, IDAT represents a significant improvement over immuno-PCR in terms of sensitivity and has the potential to provide a robotic platform for proteomics.

A methodology for improving computed individual regressions predictions.

This research proposes a methodology to improve computed individual prediction values provided by an existing regression model without having to change either its parameters or its architecture. In other words, we are interested in achieving more accurate results by adjusting the calculated regression prediction values, without modifying or rebuilding the original regression model. Our proposition is to adjust the regression prediction values using individual reliability estimates that indicate if a single regression prediction is likely to produce an error considered critical by the user of the regression. The proposed method was tested in three sets of experiments using three different types of data. The first set of experiments worked with synthetically produced data, the second with cross sectional data from the public data source UCI Machine Learning Repository and the third with time series data from ISO-NE (Independent System Operator in New England). The experiments with synthetic data were performed to verify how the method behaves in controlled situations. In this case, the outcomes of the experiments produced superior results with respect to predictions improvement for artificially produced cleaner datasets with progressive worsening with the addition of increased random elements. The experiments with real data extracted from UCI and ISO-NE were done to investigate the applicability of the methodology in the real world. The proposed method was able to improve regression prediction values by about 95% of the experiments with real data.

Hayek and complexity: coordination, evolution and methodology in social adaptive systems

The affinity between the work of the Austrian economist Friedrich A. Hayek and the approach of Complexity Economics is widely recognized by the literature. In spite of this, there still is a lack of studies that seek to analyze in depth the relationship between Hayek and complexity. This dissertation is a contribution to the filling of this large gap in the literature. In the first part of the work, we analyze the various periods in the development of Hayek\'s vision of complexity, showing that this vision is strongly present in his works on knowledge, competition, methodology, evolution, and spontaneous order. In the second part, we explore how Hayek was influenced by two of the main precursors of modern complexity theory - cybernetics and general system theory - from the time he was working on his book on theoretical psychology, The Sensory Order (1952), until the end of his intellectual career.
