 Correlation of the Church, Administration   (Site not responding. Last check: 2007-10-12)
Correlation is the process of identifying the role of each part of the Church, placing each in its proper relationship to the others, and ensuring that each functions properly.
Correlation is a unifying process in which each organization of the Church subordinates limited views to the good of the whole Church.
In 1907, the First Presidency appointed the Committee of Correlation and Adjustments; in 1908, the Correlation Committee and the General Priesthood Committee on Outlines; in 1916, the Social Advisory Committee (combined with the Correlation Committee in 1920); in 1939, the Committee of Correlation and Coordination; and in 1940, the Union Board of the Auxiliaries.

 What is Functionalism? Functionalism is one of the major proposals that have been offered as solutions to the mind/body ...
Functionalism says that mental states are constituted by their causal relations to one another and to sensory inputs and behavioral outputs.
Functionalism and Physicalism Theories of the mind prior to functionalism have been concerned both with (1) what there is and (2) with what gives each type of mental state its own identity, for example what pains have in common in virtue of which they are pains.
Functionalism tells us that what pains have in common--what makes them pains--is their function; but functionalism does not tell us whether the beings that have pains have any non-physical parts.

 Sampled speech compression system (US4270025)
A correlator, having inputs from the A/D converter and the buffer memory, correlates the digital signal received directly from the converter with a delayed signal from the buffer memory.
An "interval-select" circuit, whose input is connected to the output of the correlator, uses the autocorrelation value as a basis for comparison with subsequent peaks in the correlation value which are greater than a specified fraction of the autocorrelation value.
The interval-select circuit has an output which is connected to the buffer memory, the value of the fractional peaks and their timing being stored in the buffer memory.

 Functional Integration
The functions that are included in these systems offer a variety of capabilities and levels of access, from undocumented functions and silo applications to fully developed composite applications.
Functional Integration is based on the interaction between the components that are described in Table 1.
Many functional interfaces are tied to a specific programming language or technology because the stronger semantics of the conversation require a more detailed contract that includes the representation of method names, complex data structures, return values, exceptions, and other elements.

 ToyProblems - Traveling Termites
We introduce correlation function and correlation length as useful concepts to describe disordered structures.
Initially (for t=0), the correlation function drops immediately to 0.01 (the overall density of chips!), in other words, besides the self-correlation, chips are not correlated with each other at all.
For low overall density, the correlation lengths still seem to be growing, but for higher density (20% and 40% specifically), it sure looks as if we have reached a final state, where nothing is happening any more.

 Random sample statistical function analyzer (US3983379)
The spectra and correlation functions are sometimes required as prerequisites to deriving additional information, as for instance using the spectra of acoustic signals to identify their source and propagation paths for purposes of noise reduction or diagnosis, and similarly using mechanical signals for vibration reduction or diagnosis.
Applications of spectra and correlation function analysis, especially for high bandwidths signals exceeding 100 kHz, have traditionally been limited by the expense of the equipment that was needed.
The technique to be described is usable only for the characterization of stationary ergodic processes, examples of which are the analysis of jet engine exhaust velocity turbulence for quiet engine development and theoretical noise studies, and the analysis of acoustic and vibration signals as previously mentioned.

 BioMed Central | Full text | Correlated fragile site expression allows the identification of candidate fragile genes ...
We are motivated by the observation of a correlation between breakage levels at two very frequent fragile sites (FRA3B and FRA16D) and at a number of less frequent other ones in lymphocytes from subjects exposed to radiation and affected by radiation-induced thyroid cancer reported in [13].
Correlated patterns of expression among a few fragile sites have been recently observed by analysing a distinctive sample of subjects, exposed to radiation and affected by cancer reported in [13].
The functional characterization through GO of genes located at connected fragile sites clearly highlights that a great proportion of genes with significant annotated terms are involved in innate and adaptive immune responses and in particular in pathways characteristic of activated T lymphocytes.

 Mathematical Properties
First, note that the Wigner function derived from a steady-state (4.56) or transient solution of (4.33) is purely real-valued, because both the Liouville equation (4.33) and the boundary conditions (4.36) are purely real.
The Wigner function is obtained by transforming to the coordinates q and r, followed by a Fourier transform with respect to r.
The properties of the classical Liouville equation (4.35) employing the open system boundary conditions (4.36) are essentially the same as those of the quantum case with respect to the eigenvalue spectrum of the Liouville operator and the stability of the resulting solutions.

Abstract: An integral value calculating device is used for calculating an integral value of a function, and a function gradient calculating device is used for calculating the gradient of the graph for a function.
In the integral value calculating device, a graph display unit outputs a graph according to received data, for example, a graph of a time correlation function F(t) of the time differential W'(t) to the dynamics volume W(T), in the format applicable to an external unit, for example, a display unit.
In the function gradient calculating device, two points on a graph in which the gradient should be calculated are designated according to the position data input for a graph displayed on the display unit, for example.
