Supporting the early phases of design requires, among others, support for the specification and use of multiple and evolving representations, and for the exchange of information between these representations. We consider a complex adaptive system as a model for the development of design representations, and present a semi-constructive algebraic formalism for design representations, termed sorts...

An adaptive approach for dynamic voltage scheduling on processors is presented based on workload prediction by filtering a trace history. The effects of update frequency and filtering strategy on the energy savings is analyzed. A performance hit metric is defined and techniques to minimize energy under a given performance requirement are outlined. Our results demonstrate that up to two orders o...

The Multinational Enterprise (MNE) is recognized as a Complex Adaptive System (CAS). General characteristics of a CAS are identified and explored as to their particular relevance to organizational processes associated with MNEs. The exploration suggests useful insights into the macro behavior of MNEs. Analysis supports CAS research as a potentially valuable model in understanding the macro proc...

The natural immune system is a subject of great research interests because it provides powerful and exible information processing capabilities as a complex adaptive system. This paper describes our extensible framework named iNet for building arti cial immune systems, particularly arti cial immune networks, which has been used in our several projects developing biologically-inspired intelligent...

Biology-Inspired techniques for Self-Organization in dynamic Networks (BISON) is a three-year Shared-Cost RTD Project (IST-2001-38923) funded by the Future and Emerging Technologies initiative of the Information Society Technologies Programme of the European Commission. It runs from January 2003 until December 2005. The objective of BISON is the design and implementation of algorithms for manag...

International collaboration as measured by co-authorship relations on refereed papers grew linearly from 1990 to 2005 in terms of the number of papers, but exponentially in terms of the number of international addresses. This confirms Persson et al.’s (2004) hypothesis of an inflation in international collaboration. Patterns in international collaboration in science can be considered as network...

The development of adaptive skills is determined by factors inherent to a person, as well as by opportunities and expectations of the socio-cultural environment in which the person grows up. This paper analyses the adaptive behaviour of children with mild intellectual disability (MID) living with families or in institutions for children without parental care. The sample consisted of 95 children...

Very low birth weight (VLBW) infants require specialized care in neonatal intensive care units. In the United States (U.S.), such infants frequently are transferred between hospitals. Although these neonatal transfer networks are important both economically and in terms of infant morbidity and mortality, the national-level pattern of neonatal transfers is largely unknown. Using data on 44,753 i...

A lot of significant data describing the behavior or/and actions of systems can be collected in several domains. These data define some aspects, called features, that can be clustered in several classes. A qualitative or quantitative value for each feature is stored from measurements or observations. In this paper, the problem of finding independent features for getting the best accuracy on cla...
