In this paper, an extended simulation study is presented by which the power of modern digital identification and control methodology is tested against the nontrivial dynamics of a relatively simple yet nonelementary plant. Many critical issues which may significantly affect the success of the entire design process can be discussed along the lines of this study. The plant considered here is a liquid-saturated steam heat exchanger, where the liquid flow-rate is manipulated to regulate the outlet liquid temperature. All the numerical experiments have been conducted by digital simulation of a fairly standard nonlinear distributed parameter model. 相似文献

This paper investigates the link between firm-level innovative performance and innovation prone external environments where knowledgeable individuals tend to cluster. Organizational ambidexterity and absorptive capacities (potential and realized) make it possible for firms to leverage the availability of external knowledge and boost their innovation performance. The empirical analysis focuses on England and is based on a novel combination of Community Innovation Survey (CIS) firm-level data and patent data. The results show that only firms complementing potential and realized absorptive capacities are able to take advantage of favorable external environments by actively combining internal and external sources of knowledge. 相似文献

As universities are increasingly called by their national governments for a more entrepreneurial management of public research results, they started to develop internal structures and policies to take a proactive role in the commercialisation of university research. For the first time, this paper presents a detailed chronicle of how country-level reforms on Intellectual Property Rights (IPRs) were translated into organisation-level mechanisms to regulate university-patenting activity. The analysis is based on the complete list of patent policies issued between 1993 and 2009 by the population of Italian universities. Our evidence suggests that universities first dealt with legislative changes on IPRs by enacting isomorphic behaviours, then by creating a community of practices, and finally by leveraging on such community to influence government reforms on IP-related matters. We discuss our results in the light of institutional theory and public policy. 相似文献
