![]() ![]() Conclusions: The two factors, namely blood rheological models and inlet velocity boundary condition, exert additive effects on variables that characterize vascular flows, with negligible interaction effects. Response variables that relate to the average tangential force on the wall over the entire cycle do not differ significantly across alternative factor levels, as long as one focuses on non-Newtonian specifications. Results: The selection of inlet velocity profiles appears as a more critical factor relative to rheological specifications, especially regarding differences in the oscillatory characteristics of computed flows. Outlier- and heteroscedasticity-robust ANOVA tests assessed the simultaneous effect of rheological specifications and boundary conditions on fourteen variables that capture important characteristics of vascular flows. For each case, five rheological models and three inlet velocity boundary conditions were considered. Methods: The finite volume method was employed for the numerical simulation of seven patient-specific abdominal aortic aneurysms. The majority of results present qualitative and/or quantitative conclusions that are not thoroughly assessed from a statistical perspective. I think talking to Joe Shaw and Peter Hutterer could also be of great value to see what the history in this is exactly, how to make it a great feature request and what to expect from it.Background: The effects of non-Newtonian rheology and boundary conditions on various pathophysiologies have been studied quite extensively in the literature. The main blockers I see is that this might be very much hardware specific and therefore hard to implement. It would be very much useful to have an interface in Xorg to be able to read the absolute position values of the touchpad. I see room for a feature request on the upstream bugtracker for the synaptics driver (and possibly others). Losing the ability for two-finger scrolling, tapping, etc. Also, by using evdev instead of synaptics you're Itself, not the data in the events but then again that data is alwaysĪbsolute anyway. ![]() Note that this only changes the behaviour of the touchpad You provided you're running server 1.8 or later. The following configuration snippet will do that for You need to configure your X server to use the evdev driver for the The synaptics driver doesn't do this, but the evdev driver does. Position of a finger on the touchpad rather than just relative It was discussed back in 2010 on the Xorg mailing list (an excerpt below): The only way I see this to be possible at this moment in Linux is using the evdev driver in Xorg. Joe Shaw, author of the code and only known user doesn't have a use for Little usage of it (I haven't seen bug reports from people claiming to use Moving a touchpad in absolute mode is unusual - touchpads are disconnectedįrom the output device, so direct interaction is hard. The capability of actually putting a Synaptics device in absolute mode in Xorg has been removed recently by this commit in the xf86-input-synaptics driver: Remove absolute mode My Synaptics touchpad reports the absolute positions as follows: Event type 3 (EV_ABS) Test this for yourself using evtest in a virtual terminal (to suspend X). The absolute data is really there, as the driver can detect whether you are touching it at the edges for scrolling for example. Unfortunately, even if you have a touchpad pretty much capable of reporting all absolute values, most touchpad drivers do not let you use them in Linux applications. ![]() Some more basic touchpads don't have the capability of reporting the absolute positions.Touchpads capable of both relative and absolute modes needs switching of modes, which is very hardware specific and not application-aware.A regular application can't talk to the touchpad directly (by design), so you really have to look for a solution in the driver. Touchpads reporting absolute positions data is being translated by the Xorg driver to relative movement for the applications.You won't find a program doing this, because of these three types of touchpads the drivers tries to abstract to a single representation to applications: ![]()
