Abstract: Safety in façade systems realized with stone materials is linked to a multitude of factors, as regards the stone materials, such as: mechanical resistance values, behavior in specific environmental conditions, inner stress related to applied static and dynamic loads; as concerns the implementation process, in order to achieve safety the following specific aspects emerge: the production processes carried out to realize the elements, the quality in projecting anchorage systems and the modes of material placing. In order to define and maintain over time the desired safety levels, it is important activate a process aiming at controlling the above mentioned factors by carefully determining morphologies and dimensional characteristics, techniques of production and realization of coating and anchorage components so that slab shedding is avoided. In the text, the phases and the critical elements of such process are detected in order to define a safe-life or fail-safe façade system.

Abstract: Non-thermal plasma technique can be used to degrade radioactive liquid waste involving Tributylphosphate (TBP) producing in nuclear fuel reprocessing. The dissociation reaction caused by the collision of electrons with neutral molecules can generate active radicals which play a central role in removing TBP. And the electron reacting with vapor to generate OH radicals is the key reaction in removing TBP. A model is derived from the Boltzmann equation and molecule collision theory to predicate the dissociation reaction rate coefficients. Upon comparing with available literature, the model is confirmed to be acceptably accurate in general. Reaction rate coefficients of vapor dissociation in non-thermal plasma are derived according to the Arrhenius formula.

Abstract: The setup structure for the power grid faults diagnose system is analysed, the Multi-Agent System technique is used to the system. The functional modular of the system is transformed into Multi-Agent System, which has the same function as the entity system. The modular of the system can be in reconfiguration state when trouble appears by using Agent technique. The system running mechanism is also given.

Abstract: The problems of the multifunction sensors development make inefficient of design traditional methods application. Work purpose is an effective approach creation to the analysis and synthesis of sensors physical functional principle and creation on its basis mathematical, algorithmic and informational software for multifunction quantity sensors conceptual design automation. Authors propose the problem solution method based on fractal approach application to the theory of energy and information circuit models. For this purpose the physical functional principle sensor modeling fractal concept and mechanisms of its realization are created. This work results are new computer technique, software for the automatic synthesis of the multifunction sensors physical functional principle and two new multifunction sensors utility models automatically generated by developed software.

Abstract: A modeling analysis and verification of tunable metamaterial absorbers (MA) comprised of a new combination shaped metal elements printed on a dielectric substrate loaded with PIN diodes were presented. Unlike conventional transmission line analysis, new modeling analysis allows arbitrarily shaped elements to be calculated. A qualitative analysis by a simple equivalent circuit model is carried out on the parameters of the tunable MA. Thus, samples of the tunable MA are fabricated. The measured results are in good agreement with the predicted ones. The study shows that the modeling analysis is simple and practicable to describe the working principle of the tunable MA structure.

Abstract: The life excess of shaft part of the traditional design is a major source of industrial waste. This paper presents a vision for excess life of the shaft parts, which is expected to use the crack initiation life instead of the traditional fatigue endurance limit, achieve the purpose of reducing the excess life, try to give the method of calculation of the crack initiation life, and provide technical support for the shaft parts life design.

Abstract: A growing number of industries feel the need of formalizing their innovation approaches. Modern innovation theories and methods use different knowledge sources for solving inventive design problems. These sources are generally about similar notions, but the level of detail of their description can be very different. We are interested in finding semantic links among these sources and developing an intelligent way of managing this knowledge, with the goal of assisting the inventive design expert during his activities. This paper explores a short text semantic similarity approach to search potential links among these sources. These links available could facilitate the retrieval for the heuristic solutions of inventive problems for TRIZ users.

Abstract: A migration-driven aggregation model with catalyzed decline process of two species is proposed, in which migration-driven aggregation occurs between any two aggregates of the same species with the size-dependent rate kernel . Meanwhile, a monomer decline of A-species aggregates occurs under the catalysis by B-species aggregates with the catalyzed decline rate kernel . The kinetic behavior of A species is investigated by means of the mean-field theory, which is found to depending crucially on the catalysis rate kernel parameter μ: in case, the migration-driven aggregation reaction dominates the process, and the aggregate size distribution of A species approaches the conventional scaling form, and A species will survive in the end; while incase, the catalyzed decline reaction dominates the process, the aggregate size distribution of A aggregate does not scale, and A species will die out in the end.

Abstract: The paper describes the design, the test and the optimization of a prototype for the European Shell Eco-Marathon (SEM) competition. The design step includes the definition of vehicle shape, materials, structure, tires, power-train and control with an inter-disciplinary approach. The test phase was performed both numerically and experimentally. The vehicle, named Carla 2012 has been build at the DII (Department of Innovation Engineering) at Università Del Salento and tested on the facilities available at the Nardò Technical Center and was able to satisfy all the specifics of SEM regulation in 2012 edition. The optimization step is aimed at defining an innovative powertrain and an high-efficiency race strategy in order to achieve 3000 km with the equivalent of 1 liter of gasoline.

Abstract: With the development of computer technology, CAD / CAM technologies have been widely used in the machinery manufacturing industry. They have brought fundamental changes to product design and manufacturing method. Based on the characteristics of punching machine processing technology, the main content of this paper is the study on boards CAM key technology taking NC machining applications for boards punching as the background. This study takes VC + + software as the platform and widely applies VC + + development tools and OpenGL technology in the process of developing graphical simulation system. The purpose of this study is to achieve drawing function, automatically extract pixels in AutoCAD graph such as holes, and automatically generate NC machining program by the extracted pixels on the basis of the pixel extraction. This can ensure the uniqueness and accuracy of the data, so as to improve the efficiency of programming.
