dear leonard
more or less one month ago a question of mean frequency has been posted on
the list.
on the median frequency there are papers by de luca and merletti on IEEE
trans. BME (1988 - 1990?).
as for the mean frequency, we designed a real time algorithm for its
evaluation starting from the time history of the signal, therefore without
a previous calculation of the spectrum. the algorithm is more efficient
than those with the FFT approach. the reference paper is: Conforto,
D'Alessio: Real time monitoring of muscular fatigue from dynamic surface
myoelectric signals using a complex covariance approach, Med. Eng. &
Physics, 1999, pp. 225-234.

to

> Biomch-L Colleagues,

> I have a query that relates very closely to a question recently posed by
> John Finan (University College Dublin) on joint stiffness. Within our
> research we are modelling the Standing Hybrid III Dummy on a moving
floor.
> The defined joint stiffness of the lower limbs (particularly the knee)
> consist of little or no stiffness throughout the normal range of motion
> with a dramatic increase when nearing the end of the joint ROM. This is
to
> simulate the physical end-limits of joint motion.Therefore any upward
> movement of the floor causes the dummy to crumble. Is there any data or
has
> there been any work done on the stiffness properties of these joints in
> anticipation of an upward force? For example, the stiffness in the knee
> before landing from a jump. We are not primarily concerned with any
> increased stiffness due to increased muscle activation during the impact.
> We would like some idea of joint stiffness applied by the semi-conscious
> muscle activation in anticipation of the upward force.
>
> Your help would be greatly appreciated and a summary will be posted.

>
> Hello All,
>
> I am a mechanical engineering student from Rice University in Houston,
TX,
> with an extensive interest in sports biomechanics, particularly as
applied
> to horizontal jumping in track & field.
>
> I have been doing studies of biomechanics in the triple jump since fall
of
> 1996, at which time I performed an analysis of horizontal speed in
> Jonathan Edwards' record leap from 1995. My work over the last 4 years
> has culminated in a thesis project which is my current focus. In this
> project, I hope to obtain and analyse as much horizontal velocity data in
> the triple jump as possible.
>
> To this end, I am searching for any and all such data from previous or
> current studies. I have found little data of this type in published
> work. However, I believe there must be a great deal of this data in
> existence. Even if only I could locate position data, I could readily
> derive the velocity data which I am interested in.
>
> If anyone could provide me with information as to where I might locate
> this type of data, I would be extremely appreciative. In addition, any
> suggestions with regard to the collection of new data, or possible
> research collaborations, would be welcomed.

> I have posted a project webpage at:

> Hi Everyone:
>
> We are in a process of making a decision about purchasing an eye-tracking
system
> ( it may be head band mounted or remote desk mounted).
>
> My questions:
>
> 1. Do you have any recommendations between Applied Sciences Laboratory
(ASL)
> and ISCAN eye tracking system?
> 2. Does anyone know of any technical limitations of either systems? For
example
> ease of calibration, stray spots causing error in tracking, loss of
calibration

> 3. If you are using any one of (or both) the eye tracking system(s) can
you
> please send me your contact information so that I can directly contact
you for
> more information about the system?
> 4. Do you have any papers published on the use of the eye tracking
systems?
>
> Thanks in advance for your help.
