The Search for Indicators of ICT： Preliminary Study on Industrial Enterprises of Cordoba and Rosario

In this paper, the incorporation and use of ICT （Information and Communication Technologies） in organizations are recognized as a process that occurs in stages involving progressive levels of maturity towards the integration of the extended value chain. In the beginning, ICT are applied to the digitalization of tasks and processes within the organization that facilitates the transition to the stage of integration of information systems and internal communication. Once this level of maturity is reached, it is possible to extend the application oflCT in inter-organizational processes. The main objective of this work is to identify factors that encourage the integration of inter-organizational information systems and the development of the extended value chain. One of the difficulties that this kind of study has to face is on the lack of precise empirical tools that enable comparability of results, both in time and between sectors and countries. It is therefore necessary to perform specific works that shed light on whether the efforts of local organizations to integrate ICT enhance collaborative processes with the environment and the factors influencing these results. It was applied a mixed methodology that combines ad-hoc survey and Tool Assessment Websites, carried out on 23 industrial manufacturing companies located in Rosario and Cordoba Argentina. The search was oriented to the identification of a limited number of indicators, but with the advantage of being amenable to being followed in time, for a number of companies in the region under study. The results indicate that companies with customers and/or suppliers abroad denote a higher level of maturity in the application of ICT.

Tidal Current Energy Resource Assessment Technique and Procedure Applied in Western Coastal Region, South Korea

After the nuclear power plant accident in Japan, Korean government has set the national goal to produce the electricity by renewable energy sources up to 11% by 2035 which is not easy to achieve without ocean energy development. The demand on the clean energy supply has been increased recently and there are many renewable energy development projects and plans announced worldwide. The ocean energy can be produced from tidal current, wave, tidal barrage and ocean thermal sources. The first step is to estimate the resource assessment for each energy source. There are several assessment methods introduced from IEA （International Energy Agency）, IRENA （International Renewable Energy Agency）, NREL （National Renewable Energy Laboratory）, EU ERENE （European Community for Renewable Energy）, Bonn University, DLR （German Aerospace Center）, etc.. Even these known methods have some sort of similarity; there are different definitions and classifications among them. In this paper, the four-step energy potentials are defined and introduced as theoretical, geographical, technical and market potentials. The theories for each step are presented for ocean energies together with clear definitions. As the tidal current energy research and development are active in Korea having very strong tidal current speed along the west and south coastal regions, the detail procedure for each step of energy potential assessment is introduced for tidal current energy. The paper will illustrate the case study of tidal current power assessment in western coastal region, South Korea with highlighting the key aspects in determining the resource potentials.

Applications and research in frame longeron of hydroforming

The application feasibility of hydroforming in frame longeron large parts is verified for the first time at home. The result of the research on the structure design and process analysis for frame longeron shows that hydroforming can he fully realized. With stiffness is comparison, collision test simulation and cross section force with traditional drawing- assembly welding techniques, it has been found that hydroforming combining has multiple advantages such as light- weight, high stiffness, reduction in the number of parts, high precision, hence reduction the associated machining and welding and so on. It is especially suitable for forming various lightweight components used for the chassis parts in automotive.

Progress and trend of sensor technology for on-line oil monitoring

Oil monitoring constitutes an important and essential component of condition monitoring technologies and has distinguished advantages in revealing wear,lubrication and friction conditions of tribo-pairs.Newly developed on-line/in-line oil monitoring technologies extend the merits into real-time applications and demonstrate significant benefits in maintenance and management of equipment.This paper comprehensively reviews the progress of on-line/in-line oil monitoring techniques including sensor technologies,their scopes and industrial applications.Based on the existing developments and applications of the sensors for oil quality and wear debris measurements,the trends for future sensor developments are discussed with focuses on accurate,integrated and intelligent features along with exploring a fundamental issue,that is,acquiring the knowledge on degradation mechanisms which has not received sufficient attention until now.Current status of applications of on-line oil monitoring is also reviewed.Although limited reports have been found on this topic,increasing awareness and encouraging progress in on-line monitoring techniques are recognized in applications such as aircraft,shipping,railway,mining,etc.Key fundamental issues for further extending the on-line oil monitoring techniques in industries are proposed and they include long-term reliability of sensors in harsh conditions,and agreement with fault or maintenance determination.
