And Function

An integrated system to measure mechanical functions of material or structure is introduced. This system is able to provide more detection methods and experiment environments. And it can discover the characteristics and mechanisms of damnification and breakage in materials, considering the effects of loading and environments. Material functions were analyzed in many aspects, including loading, strain, light, sound, temperature and infrared to ensure the safety of materials and configuration of unmanned plane. Current study has laid a foundation for realizing optimal design of unmanned plane. In this paper, theory, components, and function of the system were discussed, as well as signal acquisition and analysis.

This paper presents a proposal for reconciliation between the warehouse of legal documents created during legislation and Knowledge Warehouse that is dedicated to assisting both citizens and public officers in the procedural legal rules of Public Administration in Hungary. The Knowledge Warehouse contains several thousand detailed rules that describe how to manage and handle life events of citizens. This description can be considered as generic legal cases within legal procedures of authorities. The citizens trigger specific instances of the generic ones. The evolving Knowledge Warehouse main purpose is to enable citizens to get their specific legal cases started either through Web on the Government Portal or with the help of public officers. The Knowledge Warehouse will be extended by ontologies and semantic search capabilities. An Integrated System for Supporting of Codification will be created in an on-going project that will serve as sound basis for the National Warehouse of Legal Rules. The National Warehouse pursues the prescription of MetaLex legal standards in the case of representation of electronic legal documents. The two Warehouse are strongly coupled to each other. However, the syntactic and semantic structure of both differs profoundly. The representation of e-documents within the National Warehouse is in line with ELI, the European Legislation Identifier, even the ontologies and attached semantic description concentrates on the legal documents structural elements and their interpretation. The Knowledge Warehouse focuses on ontologies of life events and procedures of authorities to leverage semantic searching. The proposed solution tries to reconcile and integrate the two differing approaches.

Resumen Compuestos alternativos en el sector de la envolvente se obtienen por extrusión de estirado de secciones y perfiles de panel de enclavamiento estrechas. Estos elementos estructurales, resistentes al impacto, tienen la ventaja de una instalación más rápida y segura, y su diseño modular les hace idóneos para muchos edificios y otras aplicaciones. Un desarrollo adicional en esta área puede ser la obtención de una alternativa sostenible a los perfiles compuestos actuales. Estudios anteriores han demostrado que los compuestos fabricados a partir de materiales naturales tales como fibras y polímeros bio-derivados, ofrecen una alternativa sostenible a los polímeros y materiales compuestos tradicionales. El objetivo de este desarrollo es reemplazar el típico perfil de acero ligero. Los perfiles de acabado también se pueden utilizar para terminar tabiques de mampostería existentes, revestimiento de ejes mecánicos y de extracción y revestimiento de la columna. Los perfiles se han diseñado utilizando bio-polímeros, reforzados con fibras naturales. Se han establecido los parámetros de procesamiento y las formulaciones apropiadas de bioresina y fibras naturales. También se ha evaluado la adaptación de las técnicas de procesamiento de pultrusión existentes a las características concretas de los nuevos biomateriales y fibras naturales. Como resultado, los perfiles de pultrusión adaptados a la construcción se han desarrollado con la incorporación de nuevos materiales y biomateriales basados en resina.Abstract An alternative composites answer in the envelope sector is the fabrication by pultrusion of narrow interlocking panel sections and profiles. These impact-resistant structural elements have the advantage of quicker, safer installation and their modular design equally answers many identical building and other applications¡Error! No se encuentra el origen de la referencia.. An additional development in this area can be the obtaining of a sustainable alternative to current composite profiles. Previous studies have shown that biocomposites manufactured from natural materials such as fibres and bio-derived polymers; offer a sustainable alternative to traditional polymers and composites. The goal of this development is to replace the typical light gauge steel profile with a state of the art bio-composite integrated system. The finish profiles can also be used to finish existing masonry partition walls, cladding mechanical and extraction shafts and column cladding. The profiles have been designed using bio-polymers, reinforced with natural fibres where possible and necessary. Proper formulations of the bioresin, natural fibres and processing parameters have been established. The adaptation of the existing processing pultrusion techniques to the specific characteristics of the new biomaterials and natural fibres has been also assessed. As a result, demonstrators of pultrusion profiles adapted to building envelopes have been carried out incorporating novel materials and bio based resin.

Gasification Process

The use of biomass due to the reduction in greenhouse gas emissions and environmental impacts has attracted many researchers’ attention in the recent years. Access to an energy conversion system which is able to have the optimum performance for applying valuable low heating value fuels has been considered by many practitioners and scholars. This paper focuses on the accurate modeling of biomass gasification process and the optimal design of a multigeneration system (heating, cooling, electrical power, and hydrogen as energy carrier) to take the advantage of this clean energy. In the process of gasification modeling, a thermodynamic equilibrium model based on Gibbs energy minimization is used. Also, in the present study, a detailed parametric analysis of multigeneration system for undersigning the behavior of objective functions with changing design parameters and obtaining the optimal design parameters of the system is done as well. The results show that with exergy efficiency as an objective function this parameter can increase from 19.6% in base case to 21.89% in the optimized case. Also, for the total cost rate of system as an objective function it can decrease from 154.4 $/h to 145.1 $/h.

The article substantiates the necessity of conducting complex ecological monitoring of agrolandscapes due to the ecologically groundless use of the land, insufficient technical and technological support, implementation of ineffective investment and innovative economic and technological solutions, disturbance of the balance of agrolandscapes through their significant plowing, consolidation of the soil, deterioration of the ratio of arable land and ecology -stabilization lands and nature reserve fund, inefficient implementation of ecological and the Emerald Network, destruction of soil (soil buffering capacity decrease), growing areas of degraded land. A scientifically-based methodology for improving environmental monitoring of agro-landscapes of Ukraine’s territory, their optimization and effective use is proposed. The stages and specifics of carrying out of complex ecological monitoring of various kinds of agro-landscapes, their functional-structural elements, main directions and parameters are presented. The necessity of carrying out of the proposed integrated system of the agro-landscapes ecological monitoring on the territory and creation of regional information and consultation centers on agro-ecological issues has been proved.
