In order to extend the life time of their Nuclear Power Plants (NPPs), most utilities are looking for ways to implement the renovation of their existing instrumentation and control (I&C) systems. For the time being, systems proposed by the I&C suppliers are mainly microprocessor-based products. These digital products provide advantages (flexibility, processing power...), but some drawbacks have to be taken into account: e.g. complexity of microprocessors, shorter life time, increasing difficulty to qualify. Electricité de France (EDF) research & development division and data systems & Solutions (DS&S) propose to share a prospective vision of the future of I&C systems for NPPs: the new generation could be favorably based on FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit) technology, with some additional work to be done regarding their qualification. After a short presentation of the two first generations of I&C systems, the paper introduces the issues attached to the introduction of such Programmable logic hardware-based technology for critical I&C systems. The expected properties and potential uses are discussed, from the utility point of view (refurbishment of existing systems) as well as from a supplier point of view. The paper then focuses on the interest of EDF for this programmable logic hardware for Safety Critical systems, with a presentation of several actions carried out with DS&S such as the IEC 62566 standard elaboration and the development of an IP for cloning the MC 6800 microprocessor.

The authors present TARO, an interactive tool to assist linguists in designing, building, testing, and extending natural language processing (NLP) systems. TARO (text analysis and representation with objects) is implemented in KSL, a reflective, object-oriented programming language. The architecture of TARO takes advantage of encapsulation, polymorphism, and inheritance of object-oriented programming to provide an environment in which testing and refinement of complex NLP components can be achieved without major program modifications. It also benefits from the reflectivity of KSL to allow building and extending NLP prototypes dynamically. These qualities, coupled with the ability of TARO to integrate syntactic with semantic analysis, provide the opportunity to achieve greater modularity, extensibility, and integration in the design of natural language systems.< >

To make higher density on optical disk, a new recording method-two dimensional recording-which can increase the track-density rather than the linear density was proposed. The performance of this method on increasing density is estimated by the simulation and confirmed by measuring the read-out signal. Consequently, it is clarified that this method can attain more than twice the areal density independently and realize the density of 2.2Gbit/in2 which is 8 times as large as that of first generation using 680 nm laser diode. © 1995 SPIE.

Vascular anomalies (VA) refer to abnormal blood or lymphatic vessel architecture, most often as a result of dysregulated growth. Venous malformations (VM), a subgroup of VAs, are triggered by activating mutations in the Angiopoietin/TIE2-PI3K/AKT/mTOR signaling pathway with TIE2 L914F (gene name TEK) being one of the most frequent mutations in patients with VMs. Although systemic targeting of the overactivated pathway is possible, it would be a therapeutic advantage to restrict treatment to only the affected lesions. To identify peptides with potential selective binding to TIE2 L914F lesions we applied in vivo phage display to TIE2 L914F-overexpressing endothelial cells (ECs) in a subcutaneous matrigel xenograft mouse model of VMs. By panning for lesion-targeting phages in combination with subcellular fractionation, a screen for cell-penetrating candidate phages was established. Employing Next Generation Sequencing (NGS) and a refined bioinformatic analysis we were able to identify many novel cell-penetrating peptides (CPPs). To pinpoint the most selective and viable CCP candidates a hierarchical clustering algorithm was utilized. This method aggregated CPPs with highly similar sequences into a small number of clusters from which consensus sequences could be derived. Selected candidate CPPs exhibited uptake in TIE2 L914F-expressing human umbilical vein endothelial cells (HUVEC) in culture and were able to deliver siRNA into these cells. In conclusion, our NGS bioinformatic-supported approach led to the identification of novel and selective CPPs capable of transporting a siRNA cargo into targeted cells. © 2024

International Conference on Tools for Artificial Intelligence (ICTAI)

作者： Saikat Mukherjee Dmitriy Fradkin Michael Roth Integrated Data Systems Department Siemens AG Corporate Research and Development USA

Analyzing spend transactions is essential to organizations for understanding their global procurement. Central to this analysis is the automated classification of these transactions to hierarchical commodity coding systems. Spend classification is challenging due not only to the complexities of the commodity coding systems but also because of the sparseness and quality of each individual transaction text description and the volume of such transactions in an organization. In this paper, we demonstrate the application of off-the-shelf machine learning tools to address the challenges in spend classification. We have built a system using off-the-shelf SVM, logistic regression, and language processing toolkits and describe the effectiveness of these different learning techniques for spend classification.

The controller for the head positioning system of a hard disk drive must have both high performance and high robustness. This paper presents a user-friendly loop-shaping design method employing the Robust Bode (RBode) plot for the head positioning system. By using the RBode plot, control engineers can easily design controllers that can suppress disturbances and account for perturbations of the controlled object with frequency response data alone. A transfer function-based nominal model is not required. As a result, the engineer can avoid the excessively conservative designs while accommodating perturbations in the plant and improve the controller performance. The design results for a benchmark hard disk drive problem show the usefulness of proposed method. © 2010 AACC.

10th International Workshop on Agents in Traffic and Transportation, ATT 2018

Transportation and traffic are currently undergoing a rapid increase in terms of both scale and complexity. At the same time, an increasing share of traffic participants are being transformed into agents driven or supported by artificial intelligence resulting in mixed-intelligence traffic. This work explores the implications of distributed decision-making in mixed-intelligence traffic. The investigations are carried out on the basis of an online-simulated highway scenario, namely the MIT DeepTraffic simulation. In the first step traffic agents are trained by means of a deep reinforcement learning approach, being deployed inside an elitist evolutionary algorithm for hyperparameter search. The resulting architectures and training parameters are then utilized in order to either train a single autonomous traffic agent and transfer the learned weights onto a multi-agent scenario or else to conduct multi-agent learning directly. Both learning strategies are evaluated on different ratios of mixed-intelligence traffic. The strategies are assessed according to the average speed of all agents driven by artificial intelligence. Traffic patterns that provoke a reduction in traffic flow are analyzed with respect to the different strategies. © 2018 CEUR-WS. All rights reserved.

We have developed an expert system for determining manufacturing order in the hot-rolling process of seamless steel pipe based on the knowledge engineering. The purpose of this expert system is to decide optimal manufacturing order, satisfying various requirements. This kind of decision making is one of the synthesis type problems which are known as the hardest one for a practical use. We paid close attention to the professionals for their ability of optimized problem solving using various broadened and unstructured standards, and then attended to systematize with the knowledge-based system technology. In this development, we confirmed effectiveness of the expert system in relation to problems involved in sequence composition, and developed its inference method.

The U.S. Coast Guard commissioned an evaluation of the appropriateness of adjusting the current limits of liability for oil spills from transportation-related onshore facilities, based on the requirements of the Oil Pollution Act of 1990. Extensive data collection and analysis revealed that the type and quality of the data needed to support recommendations for setting limits of liability for oil spills from specific categories of facilities were either not available or not reliable. Therefore, no recommendation can be made regarding a change in the limits of liability. Further, the lack of accessible data cripples decision making in the entire subject of oil spills. Recommendations are made regarding the data acquisition process and the systems needed to support it.
