Topology Aware Leader Election Algorithm for Dynamic Networks
This paper proposes an algorithm that eventually elects a leader for each connected component of a dynamic network where nodes can move or fail by crash. A node only communicates with nodes in its transmission range and locally keeps a global view, denoted topological knowledge, of the communication graph of the network and its dynamic evolution. E...
Isolation Enhancement in Microstrip Patch Antenna Arrays
Collinearly placed patch antenna arrays, printed on high permittivity dielectric substrates, suffer from an unwanted inter element coupling due to strong surface waves. A new shaped Defected Ground Structure (DGS) is proposed to suppress such waves in between elements. A low dimensional μ shaped DGS is carved out in between two E-plane patch antenn...

HOMOLOGY OF CATEGORIES VIA POLYGRAPHIC RESOLUTIONS
In this paper, we extend a result of Lafont and Métayer and prove that the polygraphic homology of a small category, defined in terms of polygraphic resolutions in the category ωCat of strict ω-categories, is naturally isomorphic to the homology of its nerve. Along the way, we prove some results on homotopy colimits with respect to the Folk model s...
Simulation of Damage Scenarios in a Bituminous Pavement Tested under FABAC ALT using M4-5n
This paper presents the use of a specific layer-wise approach to analyze the results of a FABAC accelerated loading test (ALT) carried out on a flexible pavement with an initial flaw. The approach relies on M4-5n (Multi-particular Model of Multilayer Materials) initially developed for the analysis of debonding in composite materials. M4-5n was rece...
Design of reinforced pavements with glass fiber grids: from laboratory evaluation of the fatigue life to accelerated ful...
...
In this paper we present the results of the national French project SolDuGri dealing with pavement reinforcement by glass fiber grids. In this project, an accelerated pavements test (APT) was performed on 6 pavement sections to evaluate the in situ performance of the reinforcement on their lifetime. The tests consisted in building test sections wit...
Towards an adapted ovalization system for flexible airfield pavement interface characterization using rolling-wheel or H...
Monitoring pavement condition during its service life is paramount in order to antici-pate and optimize the potential maintenance work. For this purpose, different non-destructive techniques (NDT) are used to evaluate the structure distresses condition and to provide necessary information for the maintenance tasks. On their own, they are limited to...
Controlling Packet Drops to Improve Freshness of information
Many systems require frequent and regular updates of certain information. These updates have to be transferred regularly from the source(s) to a common destination. We consider scenarios in which an old packet (entire information unit) becomes completely obsolete, in the presence of a new packet. We consider transmission channels with unit storage ...
Maximizing amount of transferred traffic for battery powered mobiles
There is a fast growing demand for mobile telephones. These rely on batteries to provide the power needed for transmission and for reception (up and downlink communications). Considering uplink, we analyse how the characteristics of the battery affect the amount of information that one can draw out from the terminal. We focus in particular on the i...
