On Optimal Dimension Reduction in Least-Square System Identification
HPL-2008-219 On Optimal Dimension Reduction in Least-Square System Identification - Fozunbal, Majid Keyword(s): Dimension reduction, echo control, least-square methods, manifold learning, and regularization Abstract: The least-square optimization problem in multi-channel echo control is severely ill-conditioned. Methods to mitigate this problem by decorrelating input signals result in undesired audio distortion. Recently, we demonstrated this approach can be tackled by dimension reduction [1]. In this paper we e ... Full Report

Hi All,
I need to identify the number of DIMMs installed on the system programatically. Are there any known methods to do this. I would like to know whether any of the UNIX kernels have support for this. I am using the SVR4.2 MP-RAS unix.

XtConfigureWidget(3) XT FUNCTIONS XtConfigureWidget(3)NAME
XtConfigureWidget, XtMoveWidget, XtResizeWidget - move and resize widgets
SYNTAX
void XtConfigureWidget(Widget w, Position x, Position y, Dimension width, Dimension height, Dimension border_width);
void XtMoveWidget(Widget w, Position x, Position y);
void XtResizeWidget(Widget w, Dimension width, Dimension height, Dimension border_width);
void XtResizeWindow(Widget w);
ARGUMENTS
width
height
border_width
Specify the new widget size.
w Specifies the widget.
x
y Specify the new widget x and y coordinates.
DESCRIPTION
The XtConfigureWidget function returns immediately if the specified geometry fields are the same as the old values. Otherwise,
XtConfigureWidget writes the new x, y, width, height, and border_width values into the widget and, if the widget is realized, makes an Xlib
XConfigureWindow call on the widget's window.
If either the new width or height is different from its old value, XtConfigureWidget calls the widget's resize procedure to notify it of
the size change; otherwise, it simply returns.
The XtMoveWidget function returns immediately if the specified geometry fields are the same as the old values. Otherwise, XtMoveWidget
writes the new x and y values into the widget and, if the widget is realized, issues an Xlib XMoveWindow call on the widget's window.
The XtResizeWidget function returns immediately if the specified geometry fields are the same as the old values. Otherwise, XtResizeWidget
writes the new width, height, and border_width values into the widget and, if the widget is realized, issues an XConfigureWindow call on
the widget's window.
If the new width or height are different from the old values, XtResizeWidget calls the widget's resize procedure to notify it of the size
change.
The XtResizeWindow function calls the XConfigureWindow Xlib function to make the window of the specified widget match its width, height,
and border width. This request is done unconditionally because there is no way to tell if these values match the current values. Note
that the widget's resize procedure is not called.
There are very few times to use XtResizeWindow; instead, you should use XtResizeWidget.
