Traditionally, clustering of multivariate data aims at grouping objects described with multiple heterogeneous attributes based on a suitable similarity (conversely, distance) function. One of the main challenges is due to the fact that it is not straightforward to directly apply mathematical operations (e.g., sum, average) to the feature values, as ...

Crystal size distribution (CSD) measurements are susceptible to the closure problem, just like chemical compositions. In its simplest form this means that the total crystal content of a rock cannot exceed 100%. Where chemical or thermal effects limit the total quantity of a single phase, closure can occur at lower volumetric phase proportions.

CSD (Crystal Size Distribution)
2021In this chapter, the basis for the tool to interpret crystal size distribution (CSD) will be explained. First, we will address the background of CSD introduction, the physical interpretation of the exponential CSD often observed in nature, and the examples of studies on CSD in nature.

This chapter presents a series of case studies illustrating how some specific central counterparties (CCPs), and central securities depositories (CSDs) have been governed in particular contexts. The following institutions and contexts are described in turn: the relationship between the Canadian Depository for Securities' owners, its users, and board ...

CSD – Commission On Sustainable Development
2000The Commission on Sustainable Development (CSD) was established in 1992 at the tEarth Summitt, the UN Conference on Environment and Development (UNCED) in Rio de Janeiro. In formal terms, the CSD is one of the nine functional commissions of the Economic and Social Council (ECOSOC), not to be confused with the Commission on Social Development.

CSD as a Therapeutic Target for Migraine
Cephalalgia, 2009To explore the effects of cortical spreading depression (CSD), an intrinsic brain event underlying migraine aura, on the excitability of the human neocortex, the authors conducted in vitro electrophysiological studies on slices from human temporal lobe that were obtained during epilepsy surgery.
