Testo completoNon-destructive Evaluation (NDE) regroups a set of methods used to detect and characterize potential defects in mechanical parts. Current techniques uses ultrasonic phased array sensors associated with instrumentation channels and multi-sensor data acquisition in parallel. Given the amount of data to be processed, the analysis of the latter is usually done offline. Ongoing work at the French “Commissariat à l’Energie Atomique” (CEA), consist to develop and evaluate different methods of advanced imaging based on synthetic focusing. The Algorithms induced require extensive iterative operations on a large volume of data from phased array acquisition. This involves important time for calculations and implies offline processing. However, the industrial constraint requires performing image reconstruction in real time. This involves the implementation in the measuring device, the entire computing architecture on acquired sensor data. The thesis has been to study a synthetic focusing algorithm for a real-time implementation in a measuring instrument used to perform ultrasonic data acquisition. We especially studied an image reconstruction algorithm called Total Focusing Method (TFM). This work was conducted as part of collaboration with the French Institute of Fundamental Electronics Institute team of the University of Paris Sud. To do this, our approach is inspired by research theme called Algorithm Architecture Adequation (A3). Our methodology is based on an experimental approach in the first instance by a decomposition of the studied algorithm as a set of functional blocks. This allowed us to perform the extraction of the relevant blocks to parallelize computations that have a major impact on the processing time. We focused our development strategy to design a stream of data. This type of modeling can facilitate the flow of data and reduce the flow of control within the hardware architecture. This is based on a multi- FPGA platform. The design and evaluation of such architectures cannot be done without the introduction of software tools to aid in the validation throughout the process from design to implementation. These tools are an integral part of our methodology. Architectural models bricks calculations were validated functional and experimental level, thanks to the tool chain developed. This includes a simulation environment allows us to validate partial calculation blocks and the control associated. Finally, it required the design of tools for automatic generation of test vectors, from data summaries (from CIVA simulation tool developed by CEA) and experimental data (from the device to acquisition of M2M –NDT society). Finally, the architecture developed in this work allows the reconstruction of images with a resolution of 128x128 pixels at more than 10 frames / sec. This is sufficient for the diagnosis of mechanical parts in real time. The increase of ultrasonic sensor elements (128 elements) allows more advanced topological configurations (as a 2D matrix) and providing opportunities to 3D reconstruction (volume of a room). This work has resulted in implementation of validated measurement instrument developed by M2M -NDT

Testo completoNeural networks have seen impressive developments since the emergence of deep learning, around 2012, and are now the state of the art for diverse tasks, such as natural language processing, classification, prediction, autonomous systems etc. However, as the research tends to focus around the optimization of a single performance metric -- typically accuracy --, it appears that performances tend to scale reliably and even predictably with the size of the training dataset, the neural network's complexity and the total amount of training compute. In this context, we ask how much of the recent progress in the field of neural networks can be attributed to progress made in compute, software support, and hardware optimization. To answer this question, we created a new figure of merit illustrating tradeoffs between the complexity and capability of a network. We used the measured energy consumption per inference as an estimator of complexity and a way of representing the adequation between the algorithm and the architecture. We established a way of measuring this energy consumption, verified its relevance, and benchmarked networks from the state of the art according to this methodology. We then explored how different execution parameters influence our score, and how to further refine it, insisting on the need for diverse objective functions reflecting different usecases in the field of neural networks. We end by acknowledging the social and environmental responsibility of the neural network field, and lay out the envisioned continuation of our work
