This experimental work is divided into two main studies, neutron sources irradiations and optical photoionization on a range of organic scintillators. Let's scatter neutrons The material for this monograph will be covered in two volumes. The measurement setup consists of an OSLD crystal connected onto the extremity of an optical fiber and a laser stimulation system, manufactured by the CEA/LIST, Saclay, France. The electronic version of the 2019 … Verifying that a concurrent program satisfies a given property, such as deadlock-freeness, is computationally difficult. This paper is devoted to characterizing plastic scintillators with neutron/gamma (n/γ) discrimination abilities and understanding experimentally the photophysical processes down-stream. This work reports on the experience arising from the master internship contract-based design tailored to safety issues for cyber-physical systems (CPS). Online nuclear counting represents a challenge due to the stochastic nature of radioactivity. Such physiological information is however very scarce in the literature and in metabolomics databases so far. ISTC Projects. Corrosion of reinforced bar (rebar) in concrete structures represents a major issue in civil engineering works, being its detection and evolution a challenge for the applied research. Objective: In this study, we explored the time course of haptic stiffness discrimination learning and how it was affected by two experimental factors, the addition of visual information and/or knowledge of results (KR) during training. Recent research proposed a combined verification approach in which a program can be incrementally verified using alternatively deductive verification and testing. Laboratoire Léon Brillouin. In this paper, test measurements of a fibered optically stimulated luminescent dosimeter (OSLD) system performed during a dedicated experimental phase in EOLE zeropower reactor are presented. Both techniques should use the same specification expressed in a unique specification language. It is based on the measurement of the air-kerma rate at a given distance from the source and the Monte Carlo calculation of a conversion factor. DIVERSITY has been designed for the purpose of managing the diversity of different semantics, but also the diversity of possible analyses based on symbolic execution. 91191 Gif sur Yvette Cedex, France +33-169085241 llb-sec@cea.fr. Relational properties, on the other hand, link several function calls. It is the largest European gathering in the fields of microelectronic design and embedded systems.The CEA will notably be present through its two institutes CEA-List and CEA-Leti. A new post-processing approach which aims at reducing the dispersion effect of the wave travelling inside a waveguide is presented. The purpose of this monograph, number 5 of the series, is to present the recommended values of nuclear and decay data for a set of sixty-eight radionuclides. Epidemiological studies demonstrated the relationship between peripheral doses and second cancers or heart diseases. A DT neutron generator, based on the 3H(2H,n)a fusion reaction, produces 14 MeV neutrons which are tagged both in direction and time with an embedded alpha detector. Model checking is an effective technique for uncovering subtle errors in concurrent systems. Software verification and validation often rely on formal specifications that encode desired program properties. In this article, we present some specific aspects of symmetric Gamma process mixtures for use in regression models. Environmental Health and Safety / Environment; Cytology, Genetics and Molecular Biology / Biotechnology and Life Sciences; Modelling and Risk Assessment / Environment; Annual Reports Annual Reports. Even if the IMRT modality allows a more accurate definition of the target volume in radiotherapy, low doses are still delivered around the tumour to organs at risk. Laboratoire d'Integration des Systemes et des Technologies (CEA/DRT/LIST) Address Ile-de-France,France. However, they usually only describe what should happen during a single call. The amount of actinides, such as 235U or 239Pu, contained in a package can be determined using non-destructive active methods based on the fission process. Moreover, the large deployment of sensors within the stations of a production line has enabled the close monitoring of products being manufactured. Tech areas. Function contracts are a well-established way of formally specifying the intended behavior of a function. Urine metabolomics is widely used for biomarker research in the fields of medicine and toxicology. 563 CEA Saclay. DIVERSITY is a multipurpose customizable platform based on symbolic execution. The count data have to be filtered in order to provide a precise and accurate estimation of the count rate, this with a response time compatible with the application in view. Naive exploration techniques are facing the state space explosion problem: they consider an exponential number of interleavings of parallel threads (relative to the program size). CEA LIST’s Laboratoire National Henri Becquerel has developed a new method to more accurately determine the iodine-125 dosages delivered to cancer patients during brachytherapy. As transistors have scaled to nanometer technology, maintaining acceptable power and energy consumption has become more challenging over the years. In the framework of the ORAMED project (Optimization of RAdiation protection for MEDical staff ), funded by the European Union Seventh Framework Programme, different studies were aimed at improving the quality of radiation protection in interventional radiology and nuclear medicine. Unfortunately, the state space explosion is the main bottleneck in model checking tools. A CEA test is often carried out after surgery to check carcinoembryonic antigen levels. Background: Stiffness perception may integrate both haptic and visual modalities. It is important to ensure the soundness of RAC verdicts, in particular when RAC reports the absence of failures for execution traces. However it becomes relatively slow when the number of memory locations in the tree becomes high. Developments involve both analogue and digital signal processing, covering all the acquisition chain … Purpose: Even if the IMRT modality allows a more accurate definition of the target volume in radiotherapy, low doses are still delivered around the tumour to organs at risk. Phone. As a consequence, characterization of the variations of the urine metabolome under basal conditions becomes critical in order to avoid confounding effects in cohort studies. A growing number of connected objects, with their high performance and low-resources constraints, are embedding lightweight ciphers for protecting the confidentiality of the data they manipulate or store. One of these techniques, known as neutron interrogation, uses a neutron beam to induce fission reactions on the actinides. Corrosion of reinforced bar (rebar) in concrete structures represents a major issue in civil engineering works, being its detection and evolution a challenge for the applied research. Partial order reduction is a standard method to address this difficulty. CoolCubeTM is a monolithic 3D (M3D) technology offering a vertical density of integration 20 times higher than face to face copper hybrid bonding (F2F Cu-Cu), thanks to ultra-thin Monolithic Inter-tier Vias (MIVs). We present WHODID: a turnkey intuitive web-based interface for fault detection, identification and diagnosis in production units. Runtime Assertion Checking (RAC) for expressive specification languages is a non-trivial verification task, that becomes even more complex for memory-related properties of imperative languages with dynamic memory allocation. An innovative filter is presented in this paper addressing this issue. Le CEA et sa start-up ARcure annoncent la création de leur laboratoire commun dédié aux systèmes de vision intelligents pour les engins industriels. One classical approach to ensuring memory safety of C programs is based on storing block metadata in a tree-like datastructure. Fault detection and identification is an extremely useful feature and is becoming a necessity in modern production units. The algorithm is tested on two examples, the mean regression problem with normal errors, and the reconstruction of two dimensional CT images. The tools use the experimental nuclear data adopted and compiled in the ENSDF file and experimental or estimated parameters of shape factors. Laboratoire d'Électronique et Traitement du Signal (LETS) stands for Signal Processing and Electronic Laboratory. CEA LIST Located at the heart of Saclay area (Paris region), the CEA LIST Institute focuses its research activities on developing innovative technologies for smart and complex systems. The main educational goal is to confront the student with realistic mixed-critical smart CPS systems, using the railway domain and autonomous trains as a case study. Here we propose a state space reduction technique for model checking concurrent programs written in C. The reduction technique consists in an analysis phase, which defines an approximate agglomeration predicate. UMR12 CEA-CNRS, Bât. They include such properties as non-interference, continuity and monotonicity. UMR12 CEA-CNRS, Bât. The Associated Particle Technique can be used to detect Special Nuclear Materials in cargo containers. A computer code for $\beta$-spectrum construction of 1300$+$ radionuclei has been created. The main objective is to improve the time domain reflectometry measurements performed over long-distance cables, relative to the wavelength λ. Let's scatter neutrons Activity measurements for thirty-two of these radionuclides have already been the subject of comparisons under the auspices of the Section II of the CCRI. Papyrus and Frama-C open source tools for example are being distributed in the whole world. Epidemiological studies demonstrated the relationship between peripheral doses and second cancers or heart diseases. It focuses its researches and development on real-time signal processing, especially for scientific instruments and measurement devices, mostly in basic physics and optics. Radiological characterization of nuclear waste drums is an important task for the nuclear industry. A real-case scenario is presented so that the gain of this method can be appreciated.
