Abstract:
Abstract We present PeerFlow, a system to securely load balance client traffic in Tor. Security in Tor requires that no adversary handle too much traffic. However, Tor relays are run by volunteers who cannot be trusted to report the relay bandwidths, which Tor clients use for load balancing. We show that existing methods to determine the bandwidths of Tor relays allow an adversary with little bandwidth to attack large amounts of client traffic. These methods include Tor’s current bandwidth-scanning system, TorFlow, and the peer-measurement system EigenSpeed. We present an improved design called PeerFlow that uses a peer-measurement process both to limit an adversary’s ability to increase his measured bandwidth and to improve accuracy. We show our system to be secure, fast, and efficient. We implement PeerFlow in Tor and demonstrate its speed and accuracy in large-scale network simulations.

Abstract:
In this study, Kernel test equating methods were compared under NEAT and NEC designs. In NEAT design, Kernel post-stratification and chain equating methods taking into account optimal and large bandwidths were compared. In the NEC design, gender and/or computer/tablet use was considered as a covariate, and Kernel test equating methods were performed by using these covariates and considering bandwidths. The study shows that, in the NEAT design, Kernel chain equating methods exhibit higher error than the post-stratification equating methods do since the lowest error in the NEC design was obtained from the Kernel equating method with large bandwidth through the computer/tablet variable. Kernel test equating results based on the NEC design, which considers gender and computer tablet use variables as a covariate separately, showed lower SEE than that of the NEC pattern, which takes these variables together as covariates. In terms of the bandwidth, when all methods are compared within the pattern used (i.e., NEAT and NEC), it has been seen that generally Kernel test equating with large bandwidth results in fewer errors than the Kernel test equating with optimal bandwidth. When the NEAT and NEC designs are compared generally, the NEAT design has a lower SEE than that of the NEC design.

Abstract:
In the context of nonparametric regression estimation, the behaviour of kernel methods such as the Nadaraya-Watson or local linear estimators is heavily influenced by the value of the bandwidth parameter, which determines the trade-off between bias and variance. This clearly implies that the selection of an optimal bandwidth, in the sense of minimizing some risk function (MSE, MISE, etc.), is a crucial issue. However, the task of estimating an optimal bandwidth using the whole sample can be very expensive in terms of computing time in the context of Big Data, due to the computational complexity of some of the most used algorithms for bandwidth selection (leave-one-out cross validation, for example, has O ( n 2 ) complexity). To overcome this problem, we propose two methods that estimate the optimal bandwidth for several subsamples of our large dataset and then extrapolate the result to the original sample size making use of the asymptotic expression of the MISE bandwidth. Preliminary simulation studies show that the proposed methods lead to a drastic reduction in computing time, while the statistical precision is only slightly decreased.

Abstract:
The first aim of this study was to obtain a more detailed picture of the effect of masker bandwidth (20 Hz to 1000 Hz bandwidth) on the masking level difference (MLD) for a 500-Hz signal as a function of listener age. The results of the pure-tone signal experiment showed that the MLDs of older children differed from adults only for the narrowest masker bandwidth. In contrast, children younger than about 7 years of age tended to have smaller MLDs than adults at all but the widest masker bandwidths. These results suggest that the younger the listener, the wider the noise bandwidth must be for MLDs of adult magnitude to be observed. One interpretation of this effect is that younger listeners require relatively great spectral dissimilarity (and, therefore perceptual dissimilarity) between the signal and masker in order to obtain MLDs of adult magnitude. The second aim of this study was to test this possibility by determining the MLD for noise signals in cases where the signal and masker bandwidths were the same. The results of this experiment showed that the MLDs of children were as large as those of adults when the signal/masker bandwidth was 320 Hz, but were smaller than those of adults when the signal/masker bandwidth was 20 Hz. This indicates that the factor limiting the MLD for narrowband noise in children is related more to the masker bandwidth than to the perceptual similarity between the signal and the masker.

Abstract:
La généralisation des nouvelles applications des communications sans fil nécessitera dans un avenir proche des communications très haut débit qui avoisineront 1Gb/s. Une des solutions proposées pour répondre à cette demande est basée sur l’utilisation de réseaux d’antennes à l’émission et à la réception connue sous la terminologie Multiple-Input Multiple-Output (MIMO). Plus récemment, les techniques ultra large bande (ULB) ont connu un regain d’intérêt grâce aux débits très élevés qu’offre sa grande bande passante et les faibles puissances d’émission mises en jeux. Si on envisage l’association de ces deux techniques au sein même d’un système, il est nécessaire, lors de l’optimisation de la chaîne de communication, de connaître au préalable les caractéristiques du canal radio. L’objectif de cette thèse porte sur la caractérisation expérimentale multidimensionnelle (MD) du canal radio pour des communications en milieux confinés. L’intérieur des bâtiments et le tunnel ferroviaire seront deux exemples traités dans cette étude. Précisons que la demande de haut débit en tunnel ferroviaire concerne les communications multimédia pour des applications de vidéo surveillance et de contrôle commande. Les travaux originaux menés au cours de cette thèse ont porté sur :- Le développement d’un sondeur de canal MIMO large bande permettant une caractérisation directe dans le domaine temporel. - La caractérisation (MD) en polarisation croisée du canal de propagation à l’intérieur d’un bâtiment et en tunnel. - l’analyse phénoménologique de la technique de retournement temporel et des diversités de polarisation, fréquentielle et d’espace appliquées aux communications en tunnel
Recent and future wireless applications require large data rates. Multiple-Input Multiple-Output (MIMO) systems were proposed as one solution to achieve higher spectral efficiency. More recently Ultra-Wideband (UWB) systems, have gained interest owing its extremely high data rates. However, precise knowledge of the radio channel is an essential issue to design the global system and, thus to reach such improvement in the performances of wireless communications. This thesis is mainly focused on the experimental characterization of the radio channel for systems with large bandwidth and MIMO. In general, most of the research on MIMO and UWB are performed in indoor environments. However, there are other scenarios where reliable communications are also needed, for example, in tunnels. In this special environment, there is an increasing necessity of developing and implementing control/command equipment, in order to develop safe and efficient trains and infrastructures. Thus, the objectives pursued in this thesis are:- Improve an existing frequency-domain MIMO channel sounder to achieve more enhanced capabilities.- Develop a wideband time-domain MIMO channel sounder in order to perform measurements directly in the time-domain.- Characterize the MIMO-UWB radio channel in office environment by means of measurements carried out in the underground level of the Universidad Politécnica de Cartagena. Multi dimensional channel parameters have been deduced from numerous measurement campaigns.- Study the propagation in tunnels and give physical interpretation of the performances of space, frequency and polarization diversity, and of time reversal techniques

Abstract:
The end-to-end Capacity and Available Bandwidth (AB) are fundamental characteristics of an Internet path and are essential for the operation of many emerging network applications. Unfortunately, ISPs have barely knowledge of the performance of the links under their control and are often unwilling to share this information. End-users are even less aware of the network conditions. Thus, several techniques have been proposed to measure the path capacity and AB just with the help of the end-hosts. However, most of these works are (i) agnostic of the underlying network technology, (ii) require a particular software to be installed on all end-hosts of the paths to be measured and (iii) ignore the impact of mutual interference when these estimation techniques are deployed at large-scale. Moreover, most studies evaluating AB tools neglect the new and emerging class of delay-based techniques which, potentially, are able to reduce the measurement overhead dramatically compared to classic approaches. In this thesis, the aim is three-fold: first, propose new measurement paradigms which take explicitly into account the network technology and do not require end-host cooperation. Second, to study the possibility of deploying AB measurements at large-scale, e. G. Including them in P2P systems or inside the TCP protocol. Third, to analyze the emerging delay-based AB estimation paradigm and compare its performance with other state-of-the-art techniques. After successfully designing three highly optimized tools, the issue of mutual interference in current AB techniques is analyzed and studied. Finally, a promising delay-based tool is implemented and evaluated against other AB techniques
La capacité et la bande disponible (available bandwidth, AB) de bout en bout sont caractéristiques fondamentales d'un chemin Internet et sont essentiels pour le fonctionnement de nombreuses applications réseaux. Malheureusement, les ISP ont à peine connaissance de la performance des liens sous leur contrôle et sont souvent peu disposés à partager cette information. Les utilisateurs finaux sont encore moins au courant des conditions du réseau. Ainsi, plusieurs techniques ont été proposées pour mesurer la capacité et AB des chemins Internet avec le seul aide des hôtes finals. Cependant, la plupart de ces œuvres (i) sont agnostique de la technologie réseau sous-jacent, (ii) exigent un logiciel particulier installé sur tous les hôtes à la fin des chemins à mesurer et (iii) ne tient pas compte de l'impact des interférences mutuelles lorsque ces techniques sont déployées à grande échelle. De plus, la plupart des études évaluant les outils pour l’AB négligent la nouvelle classe émergente des techniques basée sur le délai et qui, potentiellement, réduisent considérablement l’impact de la mesure elle même. Dans cette thèse, l'objectif est triple: d'abord, proposer des nouveaux paradigmes de mesure qui prennent explicitement en compte la technologie réseaux et ne nécessitent pas de la coopération des hôtes finals. En second lieu, d'étudier la possibilité de déployer des mesures AB à grande échelle, par exemple, les inclure dans les systèmes de P2P ou à l'intérieur du protocole TCP. En troisième lieu, d'analyser l'émergent paradigme d’estimation AB basé sur le délai et de comparer ses performances avec d'autres techniques de pointe. Après avoir réussi à concevoir trois outils hautement optimisé, la question de l'interférence mutuelle dans les techniques de AB est analysé et étudié. Enfin, un outil prometteur base sur le délai et est mis en œuvre et compare a d’autres techniques AB

Abstract:
Nowadays, Power Quality monitoring is an essential service many utilities perform for their industrial and other key commercial customers. Monitoring power quality has become specifically more effective in recent years due to the advent of the technology and software. Not only can a monitoring system provide information such as quality of the power and the causes of power system disturbances, but it is also able to identify problem conditions throughout the system prior they cause widespread customer complaints, equipment malfunctions, and even equipment failures. Power Quality problems are not necessarily limited to the utility power system. Many surveys have shown that most problems are localized within customer facilities. Essential requirements for a successful monitoring system include extensive data processing capabilities, easily understood reporting, and universal sharing of information.

Cette thèse a pour objectif d’instrumenter un contenant familier dans le domaine du biomédical et de la chimie (un tube à essai) avec des éléments piézoélectriques à ondes longitudinales (L) et d’implémenter, en les optimisant, diverses méthodes ultrasonores pour mesurer les viscosités rapidement, sans changer de banc de mesure et cela de quelques Hz à plusieurs dizaines de mégahertz au voisinage de la température ambiante. Grâce au système mis en place il est possible en quelques minutes de déterminer le comportement rhéologique du liquide, étudié en mesurant sa viscosité de cisaillement. Par ailleurs, la gamme de viscosité atteinte est extrêmement large puisque les mesures sont possibles de quelques dizaines de mPa.s à plusieurs centaines de Pa.s. Enfin, au-delà de résultats quantitatifs en terme de viscosité, le banc de mesure peut être aussi utilisé pour suivre de façon qualitative des cinétiques de réaction (polymérisation par exemple)
The main goal of this thesis is to set specific piezoelectric elements emitting longitudinal waves (L) on a well-known container in the field of biomedical and chemistry (a test tube) and to implement with some optimizations various ultrasonic methods to measure viscosities quickly, without changing the measurement bench. The measurement has to be done from a few Hz to several tens of megahertz around room temperature. Up to now it is possible to determine in a few minutes the rheological behavior of the liquid studied thanks to the evaluation of its shear viscosity. Furthermore, the viscosity range reached is extremely wide: the measurements are possible from a few tens of mPa.s to several hundred Pa.s. Finally, beyond quantitative results in terms of viscosity, the measurement bench can also be used to qualitatively monitor reactions (polymerization for example)

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California
What do you do when your downlink telemetry needs outstrip your downlink bandwidth capability? The telemetry needed to support construction and operation of the largest, most complex engineering project ever undertaken, the International Space Station (ISS), already requires utilization of the full capacity of the downlink S-band capacity, yet there are additional systems and capabilities still to be added by NASA and the International Partners. The ISS Command and Telemetry Team has developed a method of swapping packets of telemetry that are intended for special operations, while simultaneously sending essential systems telemetry and less critical telemetry that is needed on a continuous basis. To support this attempt to “make available all of the data at least some of the time” the team developed concepts for grouping telemetry into families that would always be selected as a group and then created a set of metadata associated with these groups. This metadata is pre-defined to support automated selection and scrubbing of telemetry to correspond to major upgrades in the command and control software for the ISS. The new process will at least double the effective S-band downlink bandwidth. It will also provide automated selection, scrubbing, reporting and verification of telemetry selections.

Abstract:
This paper presents an overview of the research work currently being performed within the frame of project DAAB and its successor DAAB-TX towards the integration of ultra-wideband transceivers operating at mm-wave frequencies and capable of data rates up to 100 Gbits–¹. Two basic systemarchitectures are being considered: integrating a broadband antenna with a distributed amplifier and integrate antennas centered at adjacent frequencies with broadband active combiners or dividers. The paper discusses in detail the design of such systems and their components, fromthe distributed amplifiers and combiners, to the broadband silicon antennas and their single-chip integration. All components are designed for fabrication in a commercially available SiGe:C BiCMOS technology. The presented results represent the state of the art in their respective areas: 170 GHz is the highest reported bandwidth for distributed amplifiers integrated in Silicon; 89 GHz is the widest reported bandwidth for integrated-system antennas; the simulated performance of the two antenna integrated receiver spans 105 GHz centered at 148GHz, which would improve the state of the art by a factor in excess of 4 even against III-V implementations, if confirmed by measurements.

Abstract:
In Breaks in the Air John Klaess tells the story of rap’s emergence on New York City’s airwaves by examining how artists and broadcasters adapted hip hop’s performance culture to radio. Initially, artists and DJs brought their live practice to radio by buying time on low-bandwidth community stations and building new communities around their shows. Later, stations owned by New York’s African American elite, such as WBLS, reluctantly began airing rap even as they pursued a sound rooted in respectability, urban sophistication, and polish. At the same time, large commercial stations like WRKS programmed rap once it became clear that the music attracted a demographic that was valuable to advertisers. Moving between intimate portraits of single radio shows and broader examinations of the legal, financial, cultural, and political forces that indelibly shaped the sound of rap radio, Klaess shows how early rap radio provides a lens through which to better understand the development of rap music as well as the intertwined histories of sounds, institutions, communities, and legal formations that converged in the post-Civil Rights era.

Abstract:
This handbook is aimed at helping users of PMTs who are faced with the challenge of designing sensitive light detectors for scientific and industrial purposes. The raison d’être for photomultipliers (PMTs) stems from four intrinsic attributes: large detection area, high, and noiseless gain, and wide bandwidth. Detection involves a conversion process from photons to photoelectrons at the photocathode. Photoelectrons are subsequently collected and increased in number by the action of an incorporated electron multiplier. Photon detection, charge multiplication, and many PMT applications are statistical in nature. For this reason appropriate statistical treatments are provided and derived from first principles. PMTs are characterized by a range of photocathodes offering detection over UV to infra-red wavelengths, the sensitivities of which can be calibrated by National Laboratories. The optical interface between light sources and PMTs, particularly for diffuse or uncollimated light, is sparsely covered in the scientific literature. The theory of light guides, Winston cones, and other light concentrators points to means for optimizing light collection subject to the constraints of Liouville’s theorem (étandue). Certain PMTs can detect single photons but are restricted by the limitations of unwanted background ranging in magnitude from a fraction of a photoelectron equivalent to hundreds of photoelectrons. These sources, together with their correlated nature, are examined in detail. Photomultiplier biasing requires a voltage divider comprising a series of resistors or active components, such as FETs. Correct biasing provides the key to linear operation and so considerable attention is given to the treatment of this topic. Electronic circuits and modules that perform the functions of charge to voltage conversion, pulse shaping, and impedance matching are analysed in detail.

Abstract:
AbstractOur society critically depends on data, Big Data. The humanity generates and moves data volumes larger than ever before and their increase is continuously accelerating. The goal of this research is to evaluate tools used for the transfer of large volumes of data. Bulk data transfer is a complex endeavour that requires not only sufficient network infrastructure, but also appropriate software, computing power and storage resources. We report on the series of storage benchmarks conducted using recently developed elbencho tool. The tests were conducted with an objective to understand and avoid I/O bottlenecks during data transfer operation. Subsequently Ethernet and InfiniBand networks performance was compared using Ohio State University bandwidth benchmark (OSU BW) and iperf3 tool. For comparison we also tested traditional (very inefficient) Linux scp and rsync commands as well as tools designed specifically to transfer large datasets more efficiently: bbcp and MDTMFTP. Additionally the impact of using simultaneous multi-threading and Ethernet jumbo frames on transfer rate was evaluated.

Abstract:
An overview of the design, construction, and performance testing of a small scale, uncooled, Deformable Mirror (DM) is presented. The design approach was to produce a DM which represents a low cost, high reliability device with small signal bandwidths of greater than 1 kHz, full power bandwidth greater than 100 Hz, and 4 pm of mirror surface motion (stroke). The mirror incorporates 21 actuators arranged in a 5 × 5 square array on 1 cm center-to-center spacings. Each actuator is individually addressable to provide 21 discrete correction subapertures. The mirror is constructed from conventional optical materials in a simple configuration designed to minimize manufacturing and assembly costs. Test data will be presented which indicates that all of the key design goals have been met or surpassed. A scaled version of this DM with similar temporal (stroke and bandwidth) and spatial (actuator spacing and number) characteristics would be suitable for correction of atmospheric turbulence on moderate aperture (2-4 meter) telescopes. Potential applications of this technology include ground based astronomy, ground-based surveillance and tracking, ground to space optical communication, and low power laser beam clean-up.

Abstract:
Wide-bandwidth semiconductor lasers are essential components of both long-haul multigigabit intensity modulated systems and large-bandwidth analog systems that use subcarrier modulation. Many authors have reported wide-bandwidth bulk active devices in the InP/InGaAsP system.1-3 However, despite several authors suggesting that multiple quantum-well (MQW) lasers could provide larger bandwidths,4,5 few have been reported.6

Abstract:
This document presents an analysis of the state of digital connectivity in Trinidad and Tobago and an action plan to close the existing gap between the countries of Latin America and the Caribbean and those of the Organisation for Economic Co-operation and Development. There is also a large gap within the country between urban, densely populated regions and rural, remote, or difficult-to-access regions. Among the impediments to closing the gap are: lack of investment in infrastructure in the most remote areas; limited bandwidth of citizens, institutions and companies that are far from this infrastructure; and lack of competition among internet companies. The government is making efforts in the areas of a universal service fund, spectrum management, and the formulation of the national ICT plan to improve access conditions in the country. Finally, the document estimates the investment gap in the region and in Trinidad and Tobago specifically.
