The complexity of measuring complexity
Kybernetes, 2013PurposeThe purpose of this paper is to present a reflection that can contribute to the discussion of the possibility, or not, of measuring the complexity of any given system.Design/methodology/approachThe reflection takes place considering three aspects: the first one, of an etymological character, with the purpose to specify the semantics of ...

Complex signal processing is not-complex
The 2004 47th Midwest Symposium on Circuits and Systems, 2004. MWSCAS '04., 2004Wireless systems often make use of the quadrature relationship between pairs of signals to effectively cancel out-of-band and interfering in-band signal components. The understanding of these systems is often simplified by considering both the signals and system transfer functions as "complex" quantities.

COMPLEXITY IN THE MAJOR HISTOCOMPATIBILITY COMPLEX
International Journal of Immunogenetics, 1992SUMMARYThe human major histocompatibility complex (MHC) is one of the most intensively studied regions of the human genome, containing over 70 known genes and spanning about 4 million base pairs (4Mbp) of DNA on chromosome 6p21.3 (Klein, 1986). It can be divided up into three regions: the class I region (telomeric), the class II region (centromeric ...

SIAM Journal on Computing, 1991
The importance of reversal complexity as a basic computational resource has only been recognized in recent years. It is intimately connected to parallel time complexity and circuit depth. In this paper, some basic techniques necessary for establishing analogues of well-known theorems on space and time complexity are developed. The main results are, for

Groundwater, 2006
Abstract It is difficult to define complexity in modeling. Complexity is often associated with uncertainty since modeling uncertainty is an intrinsically difficult task. However, modeling uncertainty does not require, necessarily, complex models, in the sense of a model requiring an unmanageable number of degrees of freedom to ...

This is the core chapter of this book, about the complexity of complexity. After all of the rethinking in the preceding chapters, we think we are able to present a different notion and concept of complexity that can lead to a new way of thinking in complexity. We intend to develop a way of thinking in complexity that goes beyond the complexity as taken

The Complexity of Teaching, the Complexity of Treatment
Psychiatry: Interpersonal and Biological Processes, 2007There is an old adage I first encountered as a graduate student that goes something like this: “Those who can, do. Those who can’t, teach.” According to this disparaging maxim, any incompetent can teach. By contrast, the three authors of this spare and thoughtful paper demonstrate that the transmission of clinical knowledge to aspiring mental health ...

Complexity, Complexities and Complex Knowledges
2017This discussion aims at exploring the consequences of the existence of different types of complexities in the study of socio-technical systems. We illustrate links between three different type of complexities, namely weak emergence in the sense of Bedau (2002), computational complexity and informational complexity.

The Ethics of Complexity and the Complexity of Ethics
2012In this paper, we investigate the implications that a general view of complexity - i.e. the view that complex phenomena are irreducible - hold for our understanding of ethics. In this view, ethics should be conceived of as constitutive of knowledge and identity, rather than as a normative system that dictates right action.
