Network Growth with Feedback

Existing models of network growth typically have one or two parameters or strategies which are fixed for all times. We introduce a general framework where feedback on the current state of a network is used to dynamically alter the values of such parameters. A specific model is analyzed where limited resources are shared amongst arriving nodes, all vying to connect close to the root. We show that tunable feedback leads to growth of larger, more efficient networks. Exact results show that linear scaling of resources with system size yields crossover to a trivial condensed state, which can be considerably delayed with sublinear scaling.Comment: 4 pages, 4 figure

An RPC-based Technical Trigger for the CMS Experiment

In the CMS experiment, sub-detectors may send special trigger signals, called "Technical Triggers", for special purposes like test and calibration. The Resistive Plate Chambers are part of the Muon Trigger System of the experiment, but might also produce a cosmic muon trigger as Technical Trigger to be used during the commissioning to the detectors, the CMS magnet Test Cosmic Challenge and the later running of CMS. The proposed implementation is based on the development of a new board, the RBC Balcony Collector (RBC); the test results on prototypes and their performance during the recent CMS Cosmic Challenge are presented

An agile supply chain for a project-oriented steel product network

Abstract Agility – namely, the ability of a supply chain to rapidly respond to changes in market and customer demands – is regarded as the bearer of competitive advantage in today's business world. The need for agility has traditionally been associated with supply chains in high technology industry products. However, traditional industries also face similar challenges in terms of speed, flexibility, increased product diversity and customization. This study contributes to the discussion on agility in supply chain management (SCM) and provides a novel focus on the development of an agile supply chain in a traditional industry. The object of this study is the development of an agile supply chain in a steel product network in the Raahe area in Northern Finland. The case network is undergoing a shift towards project-oriented business, where quick responses are the priority and agility is recognised as the facilitating factor. Using a constructive approach, an agile supply chain for a steel product network, SteelNet system, is developed. SteelNet system functions through the Internet and agent software technology. In identifying the new challenges raised by advanced information and communication technologies (ICT) in the development of an agile supply chain, the study presents some valuable ICT options for SCM. Following a review of the current understanding of agility in SCM literature, the study identifies the key elements of agile supply chains and proposes a four-dimensional agile supply chain framework by which to assess levels of agility. Using the framework, the study describes how the key elements appear in the case network. The study assesses the change process, and the necessary improvement steps, towards agility. It is concluded that agile supply chains have a major role also in traditional industry, and comprehensive implementation of ICT throughout the chain is of utmost importance in the development of an agile supply chain. Further insights to the discussion on agility are provided, and these and the conclusions extend a drawbridge to other companies and business networks in traditional industry to consider the clear advantages to developing their own agile supply chains

The 1st Nordic Innovation Research Conference—Finnkampen

Abstract The 1st Nordic Innovation Research PhD Conference, "Finnkampen", held in December 2006 in Oulu, Finland, focuses on a wide field from Innovation Management, Entrepreneurship to the whole field of Industrial Engineering and Management representing the specific areas of interest: regional innovation systems; technology strategy thinking and planning; product concept development, product visions, product development and process development, and product launch; evaluation and assessment of technologies; and academic entrepreneurship as well as human aspects of entrepreneurship and innovation. This book is a selection of papers written by the participating PhD students from the universities of Oulu, Vaasa and Luleå. 16 papers, presented in this book, provide best practices and novel concepts for managing innovation, improving creativity and quality, entrepreneurship, and developing regional innovation systems. The 1st Nordic Innovation Research Conference is a start for the Nordic research community's continuing development in the field on Innovation. Together the Nordic universities will build an annual Innovation Reseach Forum. In 2007, the Forum will be held in Luleå, Sweden
