Software evolves and thus developers frequently make changes to systems that are logged in version control systems. These changes are often poorly documented -- often commit logs are empty or only contain minimal information. Thus, it is often a challenge to understand why certain changes are made especially if they were introduced many months or even years ago. Understanding these changes is important...
The versatility of FTTH users i.e. the fact that users have much different characteristics in terms of requirements but also in terms of physical parameters creates an opportunity for FTTH transmission systems to optimize their performance and efficiency.
We demonstrate the co-existence of G-PON, XG-PON1 and TWDM-PON on the same infrastructure by wavelength overlay and measure the wavelength drift during the upstream burst of each technology.
Robots will be more and more present in our daily life. Even if we guess that they will help us doing our tasks, their future roles remain unclear. Thus, it is important to explore how robots implicitly influence people, in order to design their future roles. This paper investigates human's behaviors in three game conditions: game with a robot alone, a tablet alone, and both robot and tablet. Results...
This paper presents a 14nm technology designed for high speed and energy efficient applications using strain-engineered FDSOI transistors. Compared to the 28nm FDSOI technology, this 14nm FDSOI technology provides 0.55× area scaling and delivers a 30% speed boost at the same power, or a 55% power reduction at the same speed, due to an increase in drive current and low gate-to-drain capacitance. Using...
A new hybrid method, the DG-FDTD/IPO, has recently been proposed to analyze surrounded antennas mounted on large platforms. In this paper the capabilities of this method to go through such large and complex problems are shown. More precisely, a deep analysis of the far-field radiated for a canonical antenna-on-platform scenario is proposed.
This paper presents StimCards, an interactive and configurable Question and Answer game which can be applied to cognitive stimulation. This paper reviews experiments done to validate StimCards and draws up a report on these experiments and on StimCards contribution. This game is special because users can create their own questions and their own game scripts, and decide which digital devices will be...
Concern localization refers to the process of locating code units that match a particular textual description. It takes as input textual documents such as bug reports and feature requests and outputs a list of candidate code units that need to be changed to address the bug reports or feature requests. Many information retrieval (IR) based concern localization techniques have been proposed in the literature...
Spectrum-based fault localization refers to the process of identifying program units that are buggy from two sets of execution traces: normal traces and faulty traces. These approaches use statistical formulas to measure the suspiciousness of program units based on the execution traces. There have been many spectrum-based fault localization approaches proposing various formulas in the literature....
Debugging is a crucial yet expensive activity to improve the reliability of software systems. To reduce debugging cost, various fault localization tools have been proposed. A spectrum-based fault localization tool often outputs an ordered list of program elements sorted based on their likelihood to be the root cause of a set of failures (i.e., their suspiciousness scores). Despite the many studies...
This paper presents a new simulation strategy based on the hybridization of a full wave time domain multi-scale method, the Dual-Grid FDTD (DG-FDTD), and the Physical Optics (PO). This new method aims at simulating antennas mounted on large conducting platforms and whose nearby surrounding environment is very complex. Typical application fields of the hybrid DG-FDTD/PO method are the computation of...
Two types of antennas which produce Omni-directional Circularly Polarized radiation from a single feed are presented. The first antenna is a spiral top loaded crossed dipole and the second antenna is a conical helix crossed dipole. Both antennas are reduced in size to a kr of 0.3 where Left-Hand Circular Polarization (LHCP) spans across 360° of the axial ratio radiation pattern. The S11 of both antennas...
A new digital feedback control system has been developed, integrated and used successfully to control the TCV plasma. The system is designed to be modular, distributed, and easily expandable, accommodating hundreds of diagnostic inputs and actuator outputs. It offers the possibility to design advanced control algorithms using more information on the plasma state, as well as the ability to control...
This paper, proposes a new architecture to reduce the silicon area of the Cartesian feedback (CFB) used to linearize a power amplifier in WCDMA communication standard. The first stage of the previous version consists of two CORDIC structures in vector mode for the phase computation following by a subtractor. Here, we propose to merge these two CORDIC structures to obtain directly the phase difference...
The recently introduced m-vector approach uses Maximum Likelihood Linear Regression (MLLR) super-vectors for speaker verification, where MLLR super-vectors are estimated with respect to a Universal Background Model (UBM) without any transcription of speech segments and speaker m-vectors are obtained by uniform segmentation of their MLLR super-vectors. Hence, this approach does not exploit the phonetic...
Cutting-edge nanophotonic systems are increasingly displaying a magnetic, as well as an electric optical response that, for example, is integral to phenomena such as negative-index of refraction [1]. For these applications, and for many others such as those based on extraordinary optical transmission [2], the details of the response are important. For example, for negative index metamaterials the...
Near-field scanning optical microscopy (NSOM) using the aperture probe (AP) has helped to uncover exciting phenomena such as single molecule excitation [1], optical polarization singularities [2] and slow light [3]. However, the interpretations of these measurements have all been based on the assumption that what is collected is the in-plane electric near-field [2,3,4]. And, until the recent advent...
We propose a passive architecture mixing G-PON and VDSL2 technologies. We evaluate a single-user per port FTTdp prototype providing up to 100Mbit/s bidirectional bit rate per customer over 100m from the distribution point.
Nowadays, robots and virtual agents become companions for humans. They seem to have distinct roles in the Human-Machine Interaction. Thus, when developing a new application, it is judicious to wonder which the better is. In the Robadom project, a homecare robot has to assist elderly at home. The robot provides cognitive stimulation game. We developed StimCards, a cognitive card-based game. The principle...
