In Search of Memory Matter

Este artículo explora las preguntas planteadas en el desarrollo de varios proyectos artísticos durante mi investigaci.n posdoctoral, trabajando con estudios sobre memoria y materia (conceptos, metáforas, funcionamiento, perfeccionamiento). Problematizo la producción artística partiendo del entendimiento de que el observador no es independiente de la realidad y que la observación y la experiencia son construidas. En esa premisa, exploro las posibilidades de que la memoria y el conocimiento no reflejen s.lo un mundo exterior, sino un mundo interior e intento, en la obra, explorar varias posibilidades para crear empat.a y afectar al público. Los proyectos proponen una reflexión sobre los aspectos . ticos del perfeccionamiento humano y las tecnolog.as como ICC/BCI, farmacología o tatuajes digitales, planteando preguntas en torno a la memoria e identidad y posible próximos pasos en la evolución del cuerpo humano a trav.s de la instalación artística. Exploro la posibilidad de traducir las emociones directamente a un objeto como un recuerdo de un determinado momento y afirmo que cuando las emociones y las memorias están vinculadas directamente a la transformación del cuerpo y visibles al mundo exterior, cuando la tecnología nos permite enfatizar la percepci.n de las emociones en la piel, la frontera se desvanece y conlleva a la reflexión y la alteración de comportamientos colectivos.
Guaranteeing Quality of Service for the Web using Application REQUested IP over ATM

When using the Web over the TCP/IP protocol suite of the Internet there is (yet) no possibility to guarantee bandwidth or delay for the transmission of a document. For the multimedia documents of the Web, transmission with guaranteed quality of service (QoS) is however very desirable. ATM networks which are being deployed now are one means of solving this problem. They offer high bandwidths and QoS negotiation at connection establishment. Current implementations of IP over ATM do not pass these advantages of the underlying network to the application level. Making the hypothesis that standard solutions involving RSVP and NHRP will not soon be available we present a service built on a dual stack (IP \& ATM) approach which allows to transport IP streams over application requested ATM connections. We show how this service can be used to offer guaranteed QoS to Web users on ATM while preserving compatibility with users which can not benefit of ATM connections. Finally we show how this solution can even provide better QoS to Web users not directly connected to ATM.

Web-Based English Language Learning

Knowledge of another language is an advantage and it gives people to look at the world and in particular to the world’s cultures with a broader perspective. Learning English as a second language is the process by which students learn it in addition to their native language. Today, internet is an important part of our lives as English. For this reason, we can say that learning via internet is an alternative way to learn English. Web-based learning is a general term used to refer to computer-enhanced learning. It is used in so many contexts that are critical to be clear what one means when one speaks of “e-learning”. Web based technologies and powerful internet connections provide various new possibilities for the development of educational technology. The aim of this study is to review e-learning, while learning English, in a general perspective and to give brief information about web-based learning. On the other hand, it is aimed to guide learner how to use web while learning English language. The study is conducted on the base of literature survey. The study is divided into 4 parts, and all parts are entirely based on literature review. In the first part it is mentioned about the theory of web-based learning, in the second part objectives of web-based learning, in the third part some information about online students’ and teachers roles on the web are given and in the final part types of teaching-learning activities on English learning via the web are shown. This study is an attempt to give as complete a description of learning English language through the internet. There are a number of courses online which teach foreign languages. Courses usually offer a learning environment online, such as chat rooms, net meetings with the entire class, pen pal search engines and the like. In conclusion this study gives us brief information about English language learning through the internet. We can say that; this paper includes information that enables the users who want to learn English languages via the internet.
Um Estudo Empírico de Hiper-Heurísticas

A hyperheuristic [54] is a heuristic that can be used to handle any optimization problem, provided that the algorithm is feeded with some parameters, in the form of structures and abstractions, related to the problem at hand. Hyperheuristics have been applied to some practical problems and presented [57, 2, 9, 14, 16, 17, 15, 8, 13, 34, 32, 33, 59] as methods with great potential to allow the quick development of algorithms that are able to successfully deal, from a practical standpoint, with complex ill-known optimization problems. However, it’s difficult to position hyperheuristics at some quality level and evaluate their robustness without applying them to problems for which there are many instances available in the public domain and already attacked by worthy algorithms. This work aims to give some important steps towards that process of evaluation, additionally increasing the number of available hyperheuristics, studying the impact of some natural development alternatives and comparing the results obtained by different methods, what also enables us to confront the two classes of hyperheuristics that we have identified. With those purposes in mind, we have developed 3 original hyperheuristics and implemented 2 of the most important hyperheuristics created by other authors ([57] – Section 5.3.2 – and [34]). For those latter two approaches, we have also experimented with some modifications and extensions. The two methods we have chosen for implementation may be seen as respectively representing two distinct classes, which seem to contain all hyperheuristics developed so far and that allow us to classify any of these methods as either being a direct neighbourhood search hyperheuristic or an indirect evolutive hyperheuristic. We have implemented each hyperheuristic as a library (in the C language), so as to clearly show and estimulate the independence between the level where the hyperheuristic is and that to which the structures and abstractions directly related to the problem at hand belong. Obviously, this separation of concerns is extremely important to make the immediate reuse of hyperheuristics possible and enforce in them the complete absence of information from a specific optimization problem.

A method for tailoring the information content of a software process model

The framework is defined for a general method for selecting a necessary and sufficient subset of a general software life cycle's information products, to support new software development process. Procedures for characterizing problem domains in general and mapping to a tailored set of life cycle processes and products is presented. An overview of the method is shown using the following steps: (1) During the problem concept definition phase, perform standardized interviews and dialogs between developer and user, and between user and customer; (2) Generate a quality needs profile of the software to be developed, based on information gathered in step 1; (3) Translate the quality needs profile into a profile of quality criteria that must be met by the software to satisfy the quality needs; (4) Map the quality criteria to a set of accepted processes and products for achieving each criterion; (5) select the information products which match or support the accepted processes and product of step 4; and (6) Select the design methodology which produces the information products selected in step 5.
Quantitative and Qualitative Extensions of Event Structures

An important application of formal methods is the specification, design, and analysis of functional aspects of (distributed) systems. Recently the study of quantitative aspects of such systems based on formal methods has come into focus. Several extensions of formal methods where the occurrence of actions can be assigned a (fixed) probability and/or the time of occurrence of actions can be constrained are known from the literature.
New scalable cache coherence protocols for on-chip multiprocessors

espanolEn esta tesis se lleva a cabo un analisis sobre la problematica asociada a la coherencia cache en el ambito de los Multiprocesadores en chip (CMPs) y se presentan dos nuevas propuestas de protocolos de coherencia basada en hardware. Ambas propuestas van dirigidas a mitigar el coste asociado a la imperiosa necesidad de emplear jerarquias de memoria complejas dentro del chip que buscan superar la limitacion del ancho de banda a memoria (bandwidth-wall). Asi, por un lado, considerando como objetivo los sistemas multicore, compuestos por unas decenas de procesadores dentro del chip, se propone LOCKE, un protocolo de coherencia basado en broadcast y centrado en mejorar la reactividad de la jerarquia de memoria on-chip. Por otro lado, para futuros sistemas CMPs de gran escala que incluiran cientos o miles de procesadores, se propone MOSAIC, un protocolo escalable hibrido broadcast-directorio que logra disminuir significativamente el coste del mantenimiento de la coherencia hardware. EnglishThis thesis includes an analysis of the problems associated with cache coherence in the field of chip multiprocessors (CMPs) and it introduces two new hardware-based coherence protocol proposals. Both proposals are focused on mitigating the associated cost brought by the necessity of having to use complex memory hierarchies inside the chip in order to face the memory bandwidth limitation (bandwidth-wall). On the one hand, considering as a target multicore systems with tens of processors within the chip, LOCKE is proposed. This proposal uses a broadcast-based approach, which focuses on improving the reactiveness of the on-chip memory hierarchy. On the other hand, for future large-scale CMPs which will include hundreds or thousands of processors, MOSAIC is proposed. This is a scalable hybrid coherence protocol (broadcast- and directory-based) that significantly reduces the maintenance costs of hardware coherence.
Circuito conversor de analizadores de espectro de bajo coste en analizadores de redes escalares

An ultra-low cost and high performance RF scalar network analyzer for research and educational purposes have been developed. This device is based on a low cost Schottky “zero-bias” sensor diode connected to a microstrip directional coupler to measure the reflection port and a basic spectrum analyzer with tracking generator to measure the transmission port. A high impedance video output has been added to the detector circuitry in order to make compatible this device with the usual circuitry available in a basic RF laboratory (multimeter and an educational spectrum analyzer). The able to measure the magnitude of S11 and S21 scattering parameters coupled with the ultra-low cost of the circuitry, makes this system interesting tool to use by users at any level.
Avenues to understanding: A qualitative study into how students learn from multimedia

Many interactive multimedia programs direct learners down a one-way street. This paper describes a program based on a situated learning model which sought to open up the 'avenues to understanding'. Nine critical characteristics were defined from the extensive literature on the situated learning and used to inform the instructional design of a program on assessment strategies in mathematics. The paper describes a preliminary evaluation of the situated learning framework by investigating the use of the multimedia program by two students, and their thoughts opinions and feelings about learning from this type of program. Early findings indicate that it is a successful approach enabling students to construct their knowledge about the topic in an effective, non-linear, and collaborative manner.
Driver drowsiness recognition based on computer vision technology

Driver drowsiness is one of the major causes of traffic accidents. This paper presents a nonintrusive drowsiness recognition method using eye-tracking and image processing. A robust eye detection algorithm is introduced to address the problems caused by changes in illumination and driver posture. Six measures are calculated with percentage of eyelid closure, maximum closure duration, blink frequency, average opening level of the eyes, opening velocity of the eyes, and closing velocity of the eyes. These measures are combined using Fisher's linear discriminant functions using a stepwise method to reduce the correlations and extract an independent index. Results with six participants in driving simulator experiments demonstrate the feasibility of this video-based drowsiness recognition method that provided 86% accuracy.
CONCA: An Architecture for Consistent Nomadic Content Access

Future access to web-based content is likely to be dominated by two trends: (a) increasing amounts of dynamic, personalized content, and (b) a significant growth in “on-the-move” access using various mobile resourceconstrained devices. These trends point to a situation where a user would have ubiquitous access to content, but require that content be efficiently delivered to the user irrespective of location, and in a form most suited to the user’s end device. Unfortunately, classical caching and transcoding solutions do not work well together, necessitating a new caching architecture built from the ground-up to handle problems caused by dynamic content, transcoded versions of objects, and the nomadic nature of users. This paper describes the goals and architecture of such a system: CONCA, an architecture for Consistent Nomadic Content Access.
Restricciones de funcionamiento en tiempo real de un sistema automático de diálogo

En este articulo se tratan algunos de los problemas relacionados con el funcionamiento en tiempo real de los sistemas automaticos de dialogo. El trabajo se centra en una metodologia utilizada para intentar que el tiempo de respuesta de un sistema de dialogo sea aceptable por los usuarios. En primer lugar, se realiza una breve descripcion del sistema y de las diversas tareas de reconocimiento consideradas. Posteriormente, se presentan los resultados de una evaluacion con respecto al tiempo de reconocimiento, exactitud de palabras, recuperacion implicita y comprension de frases. A partir de los resultados obtenidos se puede concluir que la estrategia utilizada es aceptable para la mayoria de las tareas de reconocimiento consideradas. Asimismo, los resultados muestran que es necesario realizar cambios en la estrategia usada para otras tareas, pues la tasa de comprension es insuficiente y el tiempo de reconocimiento es excesivo para un sistema interactivo. Finalmente, se indican algunas lineas de trabajo futuro.
Exploring the use of new technologies in participation practices in legislation

The use of information technology in governance generally, and in legislative processes specifically, has emerged as a significant trend over the last decade. The design and mobilization of such technologies in diverse settings have shown significant progress over time; however, such technologies and related practices continue to reflect limitations and difficulties. This study seeks to address a number of existing limitations in the use of technology in e-legislation. Using an applied research design combined with rapid applications development, the project examines avenues for e-participation in the current investigation-legislative practices of the Blue Ribbon Committee of the Philippine Senate. The project's applications development phase uses Web 2.0 as a platform, and combines it with electronic document and natural language techniques, thus enabling a shift from dominantly information dissemination approaches to multi-directional exchanges supported by new techniques like the automatic categorization of comments. The study explores the potential and the limitations of new technologies, and highlights the need for new institutional policies and capacity building to ensure the success and sustainability of e-participation initiatives. The technologies created can be considered as possible future directions by lawmakers in countries that are seeking to move beyond e-legislation practices that focus primarily on uni-directional information dissemination, into more participatory approaches.
A Robust Loose Coupling for Speech Recognition and Natural Language Understanding

The focus of this thesis proposal is to improve the ability of a computational system to understand spoken utterances in a dialogue with a human. Available computational methods for word recognition do not perform as well on spontaneous speech as we would hope. Even a state of the art recognizer achieves slightly worse than 70\% word accuracy on (nearly) spontaneous speech in a conversation about a specific problem. pp To address this problem, I will explore novel methods for post-processing the output of a speech recognizer in order to correct errors. I adopt statistical techniques for modeling the noisy channel from the speaker to the listener in order to correct some of the errors introduced there. The statistical model accounts for frequent errors such as simple word/word confusions and short phrasal problems (one-to-many word substitutions and many-to-one word concatenations). To use the model, a search algorithm is required to find the most likely correction of a given word sequence from the speech recognizer. The post-processor output should contain fewer errors, thus making interpretation by higher levels, such as parsing, more reliable. pp Spontaneous speech is also challenging to process because it is more incremental than written language. Utterances frequently form brief phrases and fragments rather than full sentences; they tend to come in installments and refinements. Known methods for parsing do not perform as well as we would like in the face of these linguistic ambiguities and idiosyncrasies. Even state of the art algorithms for parsing spontaneous language sustain high error rates. pp To address the incrementality of spontaneously spoken utterances, I will develop methods for segmenting a given utterance into ``chunks'''' representing individual thoughts. Given an utterance of spontaneous speech, a tool for automatic prosodic feature extraction will analyze the output of the error-correcting post-processor and the acoustic waveform to generate prosodic cues. These cues will aid a robust parser using a prosody-wise grammar to identify the incremental phrases in the utterance and to provide a syntactic analysis. pp These components will augment the {\sc Trains-95} conversational planning assistant.
Network Flexibility and Policy making in Software Defined Networks

Today’s computer networks are complex which is very challenging to manage as well as these traditional networks struggle to scale to the requirements of some of today’s environment. SDN gives solution to all these requirements with new dynamic networking features that enhance server value and user services. SDN supplements traditional networking by offering much flexibility and software centric control creating a more policy based process for adding intelligence into today’s networks. Traditionally tweaking a policy/network configuration, network administrators typically rely on a combination of manual intervention and ad-hoc scripts. In this paper we have made an attempt to show how SDN is more robust and provides users flexibility to program the network according to their needs and requirements. We have used KINETIC – a domain specific language and SDN controller to write our priority based switching application.
A Tool for Lap Time Simulation

The top Formula 1 and Indycar teams make large use of computer simulation to improve the performance of their cars and make the set-up process quicker on the circuit. The paper aims to present a lap time simulation software dedicated to racing cars. It is based on the background of vehicle dynamics research developed at the University of Brescia, Italy (see [1]). It should be stated that racecar dynamics is strongly nonlinear due to the fact that tyres are always very near the limit of adhesion. Moreover this makes the effect of lateral load transfer fundamental for the general balance of the car. Therefore Pacejka's Magic Formula has been used for lateral force/slip while longitudinal force computation is based on the assumption of a maximum longitudinal coefficient of friction μ. This is not only for simplicity but it is also due to lack of available data. The combined case is then based on the so-called "traction circle". Lateral and longitudinal load transfer and downforce as well as their effects on tyre load are taken into account. The vehicle model is capable of following a trajectory acquired with the on-board instrumentation. Also, the use of genetic algorithms enables the program to find the optimum cornering line for any given track. Some results are shown and compared with real world data.
Effects of product and experimental variability on model verification of automobile structures

Experimental verification of a structural dynamic model requires vibration testing to obtain frequency response and modal data. The data are used to refine the model and assess its predictive accuracy. Although the existence of product variability and experimental variability are acknowledged, they are typically ignored in the model verification process. Models are "tuned" to match a particular set of data, usually by trial and error, and used to evaluate structural performance deterministically. Predictive accuracy is assessed heuristically, if at all. This paper describes an effort to quantify product and experimental variability based on multiple tests of multiple automobiles of the same design. These data are used to evaluate the modeling uncertainty and predictive accuracy of structural dynamic models updated by statistical parameter estimation. Quantitative results on product variability and experimental variability are presented, along with their effects on the predictive accuracy of the model.
