Abstract: This thesis is part of the research and development of surface elastic wave components for the harsh environments exceeding 600°C. The objective is the realization of surface elastic waves self-encapsulated components which can reach a temperature of 900 ° C. In this work, we introduce a modulization method allowing a finite element finite resolution of an inhomogeneous bias. This method allows to directly calculate the bias problem and to extract the parameters calculated with the perturbation method as well as other parameters. This method contributes to the improvement of the realism of numerical simulations of structures subjected to wide variations of environmental parameters. We describe in this manuscript the approach of the study, the design, the realization and the tests of unencapsulated surface wave resonators for air annealing cycles up to 900 ° C as well as a bench of measurements allowing to perform the measurements in situ. We also discuss the design and implementation of the encapsulation of these resonators by an innovative technology by Wafer-Level Packaging for high temperatures.

The 26th General Conference on Weights and Measures (CGPM) will take place in Versailles in November 2018. At this meeting, we expect the CGPM to approve a resolution to revise the definitions of the International System of Units, the SI, which is based on the second, the metre, the kilogram, the ampere, the kelvin, the mole and the candela (the SI base units).

Over the last 50 years, scientists have measured constants of nature, such as the speed of light and the Planck constant, with increasing accuracy; indeed the metre was already redefined back in 1983 in terms of the speed of light. The inherent stability of these constants make them ideal for underpinning new definitions of the SI units and preparing the measurement system to meet the future demands of science and technology.

If the resolution is approved, the SI will be based on seven physical constants, and thus inherently stable. Most notably, this will mark the end of the last remaining physical artefact in the SI system – a cylinder of metal known as the International Prototype of the Kilogram.

The work needed to reach this point has taken many years, and has been a truly international effort. The universality of access that it will afford has been a long-standing goal for the metric system, dating back more than 200 years.

L’émergence d’une métrologie quantique a permis de rattacher toutes les unités de base à des constantes fondamentales de la physique. Un nouveau système d’unités a donc été proposé à la Conférence Générale des Poids et Mesures de novembre 2018 qui supprime en particulier le kilogramme étalon matériel des unités de base. Cette évolution permet de garantir une universalité, une pérennité et une meilleure reproductibilité des mesures. Le choix des constantes va assurer une cohérence au nouveau système fondé essentiellement sur les progrès de l’interférométrie atomique et de la métrologie électrique quantique. Les développements de ces disciplines et leurs applications en métrologie seront discutés au cours de cette séance.

Conférence-débat de l’Académie des sciences, le 4 décembre 2018 de 14h30 à 16h45, dans la Grande salle des séances de l’Institut de France : “Le nouveau système international d’unités (SI) fondé sur un choix de constantes physiques fondamentales”.

The Workshop on Synchronization and Timing Systems (WSTS) is approaching 30 years of bringing together leading experts to discuss the latest timing and synchronization topics. Over this period, time synchronization has evolved from a niche application to an underpinning technology across Power, Telecommunication, Finance and many other industries and applications.

WSTS has tracked and helped the evolution of precision timing over these decades. This has allowed experts to meet and offers the opportunity to explore cross-industry innovation, as an array of timing technologies become increasingly essential to many sectors.

We particularly welcome presentations offered by the users of synchronization, especially new innovations/applications which provide an important perspective on the needs for timing and on related challenges.

For submitting a Presentation abstract, you will find that we seek either those that are relevant to a specific sector or technology area, and those that are sector independent.

Sector-related talks must choose:

• Telecom (e.g., 5G)
• Electric Grid/Power Industry
• Financial Services
• Transportation/Automotive
• Cyber-Physical Systems (Industrial Internet, Factory Automation, Computing,
  Sensor Data Fusion)
• Broadcasting and Multi-Media
• Other

For sector independent talks choose:

• Sources of Timing: GNSS, Network Links, Oscillators (Atomic, Qu, MEMS, Other)
• Timing Security/ Assured Timing
• Measurement/ System Validation
• Other

Presenting at this event positions your ideas in front of the top professionals in the timing and sync community. Please submit an abstract no later than Friday, October 5, 2018, to have your concepts considered.

The next joint meeting of the ESA Topical Teams: ACES & General Relativity and ACES & Geodesy, clocks and time transfer will be held at the Technical University of Munich, Germany, between Oct. 22, 2018 and Oct. 24, 2018. This meeting focuses on the utilization of ACES and highly accurate clocks in space, both from a point of view of space geodesy and fundamental physics. Topics of interest are:
1. The application and potential of highly accurate Clocks in Space such as ACES
2. Tests of the Einstein Equivalence Principle (EEP)
3. Laser Time Transfer using Satellites such as ACES and T2L2
4. Future applications of coherent time in space geodesy
5. The distribution of accurate time and frequency for metrology and geodesy

The colloquium will bring together the scientific community interested in the applications of highly accurate space clocks like ACES/PHARAO in all domains, from theoretical physics to cold atoms and application in geodesy and atmospheric studies. Furthermore we look at the scientific potential of near lossless links among high performing ground clocks and satellite clocks, both in time and frequency.

The meeting will consist of invited and contributed presentations on the details of ACES, data analysis and scientific applications. Whilst centered on ACES/PHARAO the colloquium is open to more general contributions on theory and experiments in any of the related subject areas. The aim is to prepare within the broad scientific community for the upcoming launch (2020), the  scientific exploitation of the data and the development of new applications in space geodesy.

The workshop will include both review and contributed talks with ample time for discussion.
