The BioElectronics Department was set up in 2009. This original research group comprises researchers in electronics, biophysics and biology on the same floor of the building. Another original aspect is its Living Sciences Platform facilities, which are available to researchers and teachers throughout the University of Bordeaux.

Our research is pluridisciplinary at the interface of physics, electronics, biology and medicine.

The BioElectronics Department is composed of three research groups: BIOEM (Bioelectromagnetism), ELIBIO (Electronics Interfacing Biology) and AS2N (Architecture of Silicon Neural Networks).

Although each research group has its own research projects, the three groups work towards a common goal to develop “real-time closed-loop solutions dedicated to biological and human applications”. The close-loop paradigm involves three steps :

1. Real-time acquisition of physiological data
2. Processing and interpretation of these data
3. Decision and stimulation (cells, organ, organism, animal, human)

Methods and technologies used for signal processing are mainly based on bio-inspired computation. This hybrid approach combining biological and artificial components makes ​​it possible to optimize the performance of systems, especially in terms of robustness and power consumption.

Created in 1971, the GRAI was a laboratory on its own until 1991 when he became a scientific operation of the LAP (and then UMR 5131 LAPS). On January 1^st 2007 the GRAI becomes the Production Engineering group of IMS. The group is led from May 2012 by Prof. Yves Ducq.

The Production Engineering group (or production engineering team in the sense of HCERES) is animated as a single entity and deploys upstream research activities, valorization of research results in the economic environment, and training of researchers and executives for industry.

Upstream research is structured in three scientific thematics that represent the fields of competence established over time and are the backbone of scientific programme. The themes are specifically animated. The PhD topics can be intra- or inter-thematic.

The three scientific thematics are:

• Enterprise Modeling and Engineering (MEI) led by David Chen

• Control of Production Systems (PSP) led by Rémy Dupas

• Design Engineering (ICO) led by Philippe Girard

Through these three complementary thematics, the Production Engineering Group has the scientific objective to provide concepts and tools to improve production systems and enterprises in three streams that are modelling, performance and control. The main recent change is to consider distributed systems.

Since the beginning of the contract, the group wanted to also highlight in its scientific diagram some application domain, even if our research is not prohibited in any way to enroll in all areas of production of goods and services:

• Manufacturing

• Services

• Transport

Regarding these application domain, the wish of the group is to not link a thematic link to an application domain but to really consider these domains as transverses.

The manufacturing domain has been widely covered by the research group but the novelty is to develop our research in the field of transport and services.

Concerning the transport domain, the main research topic was initially focused on the search for coherence in planning decisions processes, which are distributed by nature and linking manufacturers and transport providers in charge of delivering the goods to their customers.

The extension of this work to the study of the interoperability of information systems of these providers, streamlining the organization of road transport, was subsequently relevant.

The highlights of this research work are reflected in the period by different achievements or studies:

1. PRODIGE project (2009-2013) - Routing for Intelligent products. This project has enabled the development of an organizational, technological (RFID, GPS, 3G) and software (web portal) solution to instrument the road transportation, to optimize flows. The originality of the approach thus developed is the inclusion of the concept of "opportunistic" transhipment or the suitability of a transported load to "change" vehicles extemporaneously during transportation, for purposes of optimizing performance.

2. Joint work with MEI thematic has been carried out in the NOSCIFEL project with the ambition to create a data sink making interoperable the different actors of transport chain. Some works in collaboration with EIGSI La Rochelle, aimed at providing a decision support tool to formalize a participative approach throughout the project design of sustainable urban transport in a multi-criteria and multi actors context.

 Finally, concerning the service application domain, work undertaken for several years enabled to become familiar with the service concept, to understand the ins and outs and highlight specific issues of design / engineering, control, modeling and service performance measurement. In this context, the scientific project is divided into two sector axes and a theoretical axis: 1 / Service orientation of industrial enterprises and "servicization" (PSS), 2 / field of pure services with application to health and 3 / generic services modeling through theoretical studies and the return of sector studies.

SKILLS

The research skills of the production engineering group are:

• The development of models and methods for enterprise engineering for interoperability and engineering of performance indicator systems
• The management of production and transportation activities, especially the study of operational and tactical levels of the supply chain planning
• The engineering of the new product design activity in order to improve performance by facilitating collaboration between stakeholders in the design

PROJECTS

The National influence and mostly international has always been a strength of the production engineering group as its researchers have been involved since the first framework program of the European projects and continuously in all these programs. We recall for example that in the past years, the group led a Network of Excellence on the topic of interoperability for which the group is recognized as a leading group at national and international levels. This position is justified first of all by its many research findings in this area (PhD, HdR and publications) but notably also by its action within the Virtual Laboratory INTEROP vLab that was created following INTEROP NoE and comprising more than 50 organizations grouped in 9 clusters. The group has ensured the creation of the INTEROP vLab (one of the very few from a NoE), his presidency since its inception and until June 2013 and provides leadership and coordination of the Pole Grand Sud Ouest whose University of Bordeaux is a member and which includes about 15 organizations (academic and business).

The research activity of the Signal and Image Group (GSI) is concerned with the design of advanced signal and image processing algorithms. It encompasses both fundamental and applied themes, directed at long-term academic and industrial partnerships.  The key concepts, underlying this activity are modeling, inference, optimization and sampling, with emphasis on multiscale and multidimensional aspects. During the last four years, GSI has focused on subjects of importance to the national and international research communities. These include inverse problems, especially in the case of incomplete data, characterization, filtering, optimal decision, and communication.

The research activity of the Automatic Control Group is organized around three thematics:

• Thematic 1 : « Approche Robuste et Intégrée de l'Automatique », developed by the ARIA team with David HENRY as head;
• Thematic 2 : « Fractional Systems», developed by the CRONE team with Pierre MELCHIOR as head;
• Thematic 3 : « Flatness and Fault Tolerant Guidance », developed by the FFTG team with Franck CAZAURANG as head.

The Electronic Design group of the IMS Laboratory relies on three teams (known as CAS, HSC and NSC) dedicated to analog, RF and digital circuit design. It forms a powerful complementary work force to provide fully integrated solutions to complex electronic systems. This team consists of 8 Professors, 11 Associate Professors, 15 PhD students, 1 IGE, 1 IR and 1 secretary. Below are summarized the major activities and highlights of this group over the period 2009-2014:

• SASP (Sampled Analog Signal Processing) circuit in the receiving system and original solutions to the transmitter, ie the system Riemann pump and Walsh transmitter to generate one or more modulated signals over very wide bands.
• Development of an original radio demodulation principle called "MOOD" to reduce the power consumption by a factor of 10 compared to the commercially available solutions. This new receiver has also the advantage of being compatible with 2 types of the most common modulations in WSN: Frequency (FSK) and amplitude (OOK).
• Realization of a 100 GB/s clock and data recovery in 130nm SiGe BiCMOS technology, STMicroelectronics.
• Design of RF power amplifiers (PA) and mmW for LTE applications (collaboration ETS), WiGig (Cifre common lab ST / IMS), RADAR X-band / Ku-band UWB using CMOS technology, CMOS SOI, SiGe, GaN.
• Development of PA linearization techniques such as Doherty, Cartesian loop feedback, Envelope Tracking ...
• Passive Filter Design using BAW technology and active filters design using AsGa and GaN technology.
• Characterization and modelling of analog to digital converters (ADC) and digital-to-analog converter (DAC)
• New method to compensate mismatch errors in Time Interleaved ADC (TI-ADC)
• Digital Improvement of analog and mixed circuits

Main Interests: Reliability is an essential challenge for remote electronic equipment as found in ICs. It enables cost-effective design (economic aspect), improvement of manufacturing capacity (eco-friendly aspect), lower early failure rate and better management of failure prediction (user-safety and -satisfaction aspects). The Reliability group deals with all of these issues in a component-to-system approach.

Context: The performances of components, assemblies, and systems, keep improving while their integration density keeps increasing. In this context, the technological fields addressed by the Reliability group regard the reliability of all the units that can be intended to all of the integration levels of on-board or embedded electronic equipment from the silicon state to a whole operating system. This research field is thus multidisciplinary and multi-domain by nature (multi-physics, multi-time-domain, multi-material and multi-scale).

Goals: The group expertise and research are focused on the development of innovative reliability methods for components and systems dedicated to embedded and on-board systems, in order to:- control chip-package interactions- assess electromagnetic disturbance influence on reliability- control the durability of semiconductor-based power components and novel energy storage systems- contribute to new qualification standards for components and systems in a specific environment- develop aging models and to add reliability considerations to virtual prototyping
