The results of a project on news segmentation at Radio Nacional de España (RNE) carried out by the RTVE Technological Innovation and Media Management areas is presented. The aim of this project is to apply artificial intelligence to automatically transcribe and cut the news items that make up a radio news program. The main goals of this project are to increase the accessibility of the content and to allow its reusability on various platforms and social media. The project was planned in two phases, covering system configuration and service delivery. The minimum quality criteria required were defined in advance, both for automatic voice transcription and for news segmentation. For the speech-to-text process, the highest word error rate (WER) allowed was 10%, while the precision rate for the news segmentation was 85%. System performance in both transcription and segmentation was considered to be sufficient, although a higher degree of accuracy in news cutting is expected in the coming months. The results show that, despite using these quite mature technologies, adjustment and learning processes and human intervention are still necessary. Resumen Se presentan los resultados del proyecto para la segmentación en noticias de los informativos de Radio Nacional de España (RNE) llevado a cabo por el Área de Innovación Tecnológica de Radio Televisión Española (RTVE) en colaboración con la Dirección de Medios de RNE. El objetivo de este proyecto es aplicar la inteligencia artificial para el cortado automático de las noticias que componen un informativo radiofónico, para su posterior difusión en la web de RTVE y en medios de comunicación social. El proyecto se planificó en dos fases: una primera de configuración y ajuste del sistema, y una segunda de prestación del servicio propiamente dicho. Los criterios de calidad mínimos exigibles se definieron previamente, tanto para la transcripción automática del habla a texto, para la que se estableció una tasa de error por palabra máxima (WER) del 10%, como para la segmentación de noticias, para la que se definió una tasa de precisión superior al 85%. El rendimiento del sistema tanto en la transcripción como en la segmentación se considera suficiente, si bien se espera alcanzar un mayor grado de precisión en el cortado de noticias en los próximos meses. Los resultados ponen de manifiesto que, a pesar de ser tecnologías bastante maduras, son necesarios procesos de ajuste y aprendizaje con la intervención humana.

An Auto Smart Car Cover System is a car covering system which is invented for the purpose of protecting the vehicle here in this case vehicle is a car and this system can also be a good open Parking Solution. This system is guided by Electric Motors (Servo Motors), Sensor (IR or Ultrasonic Sensor), Bluetooth Module (HC-05), CP-2102 USB to TTL Module, A MC ATMega 328P on a Self Made ARD. Uno board. A Guiding Wire for guiding the Structure, and Software IDE (Arduino IDE) for Programming the MC. The Heart of the entire System is MC ATMega 328P which is completely responsible for entire operation of Cover from collecting data from sensors till Opening(Uncover) and Closing(Cover) of Vehicle.

The study proposed in the paper is aimed at determining the optimal (rational) parameters of building of an antiaircraft defense (AD) system of surface ships formation in case of anti-ship missiles attacks threat, namely: bearings and distances of the сore ships location and escort ships in the AD formations, taking into account the restrictions associated with the accomplishment of assigned combat missions, the target allocation of antiaircraft fire weapons of ships, both collective defense and self-defense, when repelling AShM attacks, combat readiness modes of the AFW, taking into account their technical reliability and duty schedule in the interests of AD, sectors of the combat use of electronic warfare, taking into account the electromagnetic compatibility (EMC) with the used AFW, orientation sectors of fighter aviation taking into account the compliance with security measures when using together with AFW. The multicriteria optimization methods using for the developed simulation model of the AD system functioning of surface ships formation in case of the AShM attacks threat in the specific conditions of the tactical situation allows obtaining the necessary practical recommendations on the ships formation in the AD formation, designation of combat readiness modes, duty schedule and the organization of the combat using of AFW, EW facilities, FA orientation in the case of the attack threat and the direct repelling of AShM attacks from one or several directions, it corresponds to the building of an equal-strength antiaircraft fire covering system, considering the available composition of the forces and AD facilities of the formation ships.

ABSTRACT The state-of-the-art silica–rubber coupling is based on forming chemical links between a silica surface and rubber macromolecules. However, the chemical links are relatively short and stiff, thus in case of a chemical breakage they are highly unlikely to recombine. This could result in a potential deterioration of the interphase properties over time. To overcome this drawback, a new approach to silica–rubber coupling was investigated in the current study. The new approach is inspired by the Velcro hook-and-loop system from nature that facilitates a re-connectability, thus re-formation of the interphase properties in case of a breakage. For this, various long oligomeric brushes were grafted onto silica surfaces considered to act as supramolecular hooks. Such modified silica were dispersed in rubber and vulcanized. The resulting cross-linked rubber matrix is considered to act as supramolecular loops. The prepared vulcanizates were compared with reference samples containing common coupling or covering agents. The reinforcing potential provided by the newly developed system is lower than the chemical coupling system but considerably higher than the covering system. The new system also provides better mechanical properties, recovery after cycling stretching, and heat treatment than the references. A new reinforcing mechanism is proposed for the silica grafted with oligomeric brushes that exhibits a good chemical compatibility to the rubber matrix.

Industrial Symbiosis (IS) is a collaborative cross-sectoral approach to connect the resource supply and demand of various industries in order to optimize the resource use through exchange of materials, energy, water and human resources across different companies, while generating ecological, technical, social and economic benefits. One of the main goals of IS is the set-up of advanced circular/cascading systems, in which the energy and material flows are prolonged for multiple utilization within industrial systems in order to increase resource productivity and efficiency, while reducing the environmental load. Many Information Communication Technology (ICT) tools have been developed to facilitate IS, but they predominantly focus on the as-is analysis of the IS system, and do not consider the development of a common desired target vision or corresponding possible future scenarios as well as conceivable transformation paths from the actual to the defined (sustainability) target state. This gap shall be addressed in this paper, presenting the software requirements engineering results for a holistic IT-supported IS tool covering system analysis, transformation simulation and goal-setting. This new approach goes beyond system analysis and includes the use of expert systems, system dynamics and Artificial Intelligence (AI) techniques, which turn the IT-supported IS tool to be developed into a comprehensive and holistic instrument with which future scenarios and transformation paths can be simulated.
