OK so we move on to the final paper in this session which is constant and you set of tools for the jury integer morphological analysis going to grow the presented by value because not OK and then so
as I said to at the same thing I consider myself and the final user some of the things I am presenting so and that the complete you computer
science and scientists from that point of view I am pretty much and material and but the on the other side there are many bits of the issues using the fact that and when I find an Niagara it I want to be sure and the way it works so the idea of being the code of the of all what I am using is very important and then before and knowing that to to do some research on ideology and geomorphology and that that some of the properties and what I am presenting today someone of you so this time we toppled games and that's essentially the properly the set of all the routines that have much fewer than 2 because the with the Baron by and by 0 which means that we can defend the coordinates of each other essentially the tried to get where found that the moment and I wrote down some of the key is that the input and output In addition of all manner and whether a cold and the 2nd well everything cold maybe not much and optimize but they're easy to read and there are compatibility is done today and in the popular analyzes terrain so that in much of the thing that presenting the the work I did with that of the about novel and that that that that work is in the book so you can immediately property but networks published by Cambridge University Press when I think best thing I think it stuff like that so essentially things a network at the beginning I was thinking only to the network not the best thing between the branching structure that you see and the relation between the structure of the the branching and and the things later on
and thought to be encoded the the right of debate in which means you have little side but in the end that what I did in the last few years with the problem my my students another collaborator is implementing this that we call the hot and cold so much and it appears that do several things at that different color log in indeed the blue 1 of those that we will never implementing to last because they are already there and the group that the good news is that that they were completely that things so is independent they have all the all the work banging on graph the red wine out those we already implemented in the what we we call them In the talk we did this supplier in the inside the ground and then brown 1 of those that are related to characteristic of the network more than the data structure and the black line I don't know exactly how to classify by the model as they worked on the on the inside and the green ones are tools that used to collect into kind of statistics on that and I will show you some examples all of them later on and finally the the last time of the year and the only 1 of these is where I think that is really a problem of fundamental problem problem to understand maybe on the PGA public contributing Iike relation as well I think I have something to say and then filtering and direction we can and I would be there then put it on their monthly because all of this work is based on who knows routines so and now let's go to there implementing being the in the last an undersampled mandatory for it will prevent some days ago the then a very nice interface program graph which is the 1 you see and then that either some of the there there and the people that we already ported out here and the program and supply the the the the the and I thought or beta version is there I hope for the point of view of the parking and they say data from the point of view of their new and of the work and then so maybe you will write some ranging mediation macaroni English and the all of the cut on the cusp of common thing Italian irony that the kind of thing so I apologize for that and then you see that the 1st line of the program so when you choose for instance year I think that used to derive them this shows that the programmer which I illustrate later on then there
automaticaly are collective in red you see many other subprogrammes that other than the fact that the 2 to run the final 1 so that I think can mediate the fact that you have do to run may be that 1 of these applications and then the thing that they provide you with the right way obviously if you already got that be some of the some of the key you can then select and and work so there is also a need for the if you just right there the question mark on that famine explanation we sometimes more of you're it will evaluate your back but it would be much you in a few months and then OK and that when you select finally to run and then that run the program and you are for the the input
5 and you can feel this this form here so it should be it should be pretty easy to work with with it I'm not so sure we use some of the that's not all the views of the implementation of the sum of all the things that are more or less trivial from the point of view of the whole some presentation right so this morning 0 24 some purple or in or yesterday on the and maybe more or less so that we need some part of the work and about the I decide to to get the feature to that provide some some questions some open problems that I think it is important to know what do we call it the polarity and the flooding I agreed to that to have a brain and directions in the time that we used to have model and we cannibalize from software about by David Baltimore and their and reporting to the last solids modeler and uses this in black and the same the and then have the feeling that people have some problem in my view which is especially here where we and work with a larger we sometimes there we wanted to view that these 2 the to have running direction because many many times many being depends on the but and maybe this is it is not always the the option sometimes you want to add a lake like at the hold at the end then maybe we we want to have it so we have to I think to think in new format for there also being it in a transparent way late of people and things like that to the pilot a way to read the fire in how to putting in the form of time other way that the other thing that I want to emphasize that the expansion of the network you is by far not the simple problem to define the word of the channel beginning is that is very debate I am reviewing 2 papers on it in this moment so in also on the side there is much attention has to be paid on their and what the researchers and doing that this is exactly the flow direction directions and that all OK I have another thing to say on all directions that the here I think that there much emphasis was in the last 2 years from the multiple directions and I think is more or less the and the wrong perspective in the sense that and you need more people call you have to problems and I think the most of you know a lot about the same sample not and that 1 problem is so when you have that the slope of the tree is not a new state that direction we see you see here when you read about it that it agreed boys it would be only this year the things you cannot address exactly their in the gravity and so you have with this kind of error that is much more very much important so I think that and I think that the the more the important area that we do when we put our about including the other areas that usually say that you have to distribute the water column there are and build fell just because you are but in convex a convex surveys sometimes people the then I don't understand that the are worth is that complex so grave and in my case I am rather water moves on on this so and when you are in a complex bar and the convex part of that of the things you and you use agreed you have been model and that that the people at the center is not well defined because you can have but if you get the friend there's going to be a directional 1 part and the direction and the other part of the peaks if the curvature is large but usually it is not and I think that this part of the work should be implemented not jumping the following their election indeed coup in there I during that Kuwaiti
I on that so that the point that they what I wanted to emphasize locations locally OK yes we did um about curvature I have an approach I put this 1 because they have that an approach to divide the uh this imperative there which is and minimally peak approach on what you call yesterday my mom mom orbital and my market of or less and use 9 Fiat faces and time the plot on curvature and then in the hope that and if you get get the right so afraid you put them in what number 1 2 3 4 provisions you get some more photo ponders replace it is not usually been there and the way it works but because of the DM are not so good and I think there are some their weighted by element of of of you that's a nice way to get the BEL-book pp things that we have also faces and the and we cannot deal with its use in the well and I think that the next time and when I have to do some more of that say a workshop on how to use the patient to avoid them and not the not the 2 catalyst way being honest with OK this is just the then I think the normal curvature we implemented there is essentially the same argument that page the by young and and the other 1 thing is that in our about aspect that the normal curvature is not their core I am time around and that if you have tangent curvature and you have provide curvature about the for many application is not by curvature is important so you eventually have to divide by the female patent that it won't let anything that but if should be that that levels so that option and that the way that is wonderful to implemented and that it is a simple way to do big uporabnik set subdivision actually freaky the operator DM from the classical point of view but if you got to investigate the reply curvature of this you see that you really have user waving that is valuable for many the perspective we call that plastic bottles that some because particles was 1 of Jim apologies to you will put the faces and then I discovered that you in 10 years before and another guy even 20 years before about the name the main and then you believe them to divide the this would be the induced in this way is that that have prostitutes acting on hill slopes or on the volleyball team are very different from the sediment transport point of view and also from that there I logical point of view we have review of maybe the 1 thing that it is not absolutely you knew but that the plot of the distance from the out from any point here the device the most of divide the more like that the ego's actually the the the Ivory water going downstream never upstream much easier much again also and then In this paper you say you want to know how long the the mainstream where you are thinking in on this quantity gives you better that nature and that it is important for either logical purposes because model Let interrelated today concentration times and we will see later but also there are some geomorphological low and no nodes I like hot flow that the and of a lady then it is a little bit more complex actually about model and this is the dialog lying on the on the ordinate you have the people who do not and you you have and is more or less and straight lines and the level of plane and the quality of the larger then on Friday so idea that they keep
the structural properties that are not fractality of the illuminating a thing that is going on from then yeah the of that other contributing out of up to slope catchment how someone calls maybe with more etymological regional is firm I already told the ball that is a single direction not multiple plot we implemented also people call about the uh from the statistical point of view that in no way to that correct I think and opinion that the water closing 1 the more or less in there and very fast floating into the but we can the data the on it and then I think that the in library at a player here in the convex part that there you should take into account all that eventually all of them curvatures not in the flowing direction that should be my opinion single the action another thing that we divide model from the other uh picture you so that that was Akilam there in which means that when you go be there and the ball a simple-minded to water if you want the way you do that a logical bonds you want to use a 1 particle that their presentation we don't we will want particle here and you will hear it is M if you have if you have only 1 that that is the case for time that that is along lead to the true that being extremely bank where there China polarity is more or less contribution you have on the page partially constant I have for what got all the lump well you have a different polarities so you have more or less this particle in this particles pain more time the in the hills some of to have ever in their right representation of the distance you have to stretch
their use own and and that is the other scalable but if you do that but this is the distribution of this 1 you obtain another doctor that we function which is a concept that more about less that came out from Michael Carrick being made but obviously there is a work by other read think 1921 that moral the preemptive use this kind of thing then the but there's 1 more or less the the the coordinate logical the unit tied around the core of a transformation that is that if we convolve this part we then uh with the effective rank you can get these so the helpless and I can tell you that this method ethene bulletin he keys users the barrier is working very well within several simulations that there is another story more or less at the view of the local ideology From the point of view albeit speech of Berkeley University which means that in there and there what you see on their on their own on the vertical if the degree is destroyed then is spending time Italian animal work should be lobbying degree and that's why I and that she so you have been contributing divided by the unit called the way is supposed to be applied to to smaller cage mandatory you love and also here at the anode and then depending on different processes different properties that different equations and the you you are you in in the idealized world world aware ideology is is more or less in equilibrium you get you get some solution you can frame and you can divide this playing end here you have a lot more or less land you you have to hold off on the part of the the formation of all the models the world and you can the and you know that laughter line that they need a lot of work in the Parliament dependent on the end of the week you from the of the or maybe slide the broader welcome to the and you have clue there are a you can you the travel if you find problem the theoretical point of view is to understand what is In any case the was my future is that the moral and the blue line divided concave points from convex what In yeah it is not true if you put that normal M over here you don't have the illusion and that is why are mostly when there is division to mark all of you won't feel and you would have been gone too long where most of the geological on the and that's what I was looking being there yeah yeah we look at the whole statement we have about so we may have a little bit that's now that we have the small medium and you and so the afraid it also in this way and the based on the 3rd and that was in the previous in the previous 3 minutes the pitch and collaborators the that the simple form of model of land sliding you that you that you can explain the foreign the rupture of additional so in end and the simple ideology equilibrium ideology we don't know we can eat this really like that but there not of which is more or less effective reasonable In that you define actually not 2 classes but for classes because of class is that this is the slope the slope more than and yet and yet and internal angle of the Xerox Europe there so if they have their but they much of Iraq you have no solid that the yellow part here is not coming down because it's not rock actually is that in this case the particle is that is a long studied the particular type of work and the table Bloom is more if table the Green is the table but conditionally to the ideological condition then the dark red is in Table the model is pretty much you have a confirmation that I had model and that out other tool the model that I know that works more at the same 1 if you to tune I don't remember the names of aII due to that at the bottom and the arc and because the model you can always find it in the find being the online and they you work on the same concept they changed the little bit the classification of the of the output and otherwise you who and other guy In this remember the name of problem this moment and should everything you about that is that the model is more or less the same he died the day the ideology we with a model of the regardless of ideology and a little bit complicated I hope to have shown you some of the problem that we have and many of them can come out we talk later on them what the next week you want to port all the repeating that our model duplicates and that work over time and on the right in the communication is not a 2nd it is not it's very important might life to actually I wrote that small command to them to get the communication from the and my source code my now I know that when I and my market for all to see it as a sole attack ideally about and ideally I hope that you can work so many 5 have to build up with more or less the know with some maybe by going over shallow managing because a win I We need to collecting and little way and there and the communication which is seen that there 105 so it's going to and then the problem too so correctness of whom but particularly we began constructing less time with from the Klaus will bring you to you for really the of this kind of thing and another thing if the 2 and fractal analysis that was pretty much involved the many type of fractal analysis in the path and I never produce actually there the final of what I know how to do it won't last if someone want to that I have been mounted delete I can tell you it is enough to work that they want to do by myself and I believe I know about walk the they 1 quick
