This plugin provides a RSSReader for TiddlyWiki. If TiddlyWiki is viewed over HTTP, RSSReaderPlugin requires a ProxyService.
See examples : <<tag RSSFeed>>.
See documentation : RSSReaderPluginDoc
if NestedSlidersPlugin is available, item contents are folded.
//last update: RSSReaderPlugin v 1.1.1//
!Description
This plugin provides a RSSReader for TiddlyWiki
* It accesses asynchronously an RSSFeed
*Depending on the chanel item format, each item could be written as :
**simple text wikified
**html
!Usage
{{{
<<rssReader noDesc|asHtml|asText rssUrl ['filtering string']>>
noDesc: only title of item is printed
asHtml: if you know that description contain html (links, img ...),
the text is enclosed with <html> </html> tags
asText: if the description should not be interpreted as html the
description is wikified
rssUrl: the rssFeed url that could be accessed.
'filtering string': if present, the rssfeed item title must contained
this string to be displayed.
If 'filering string' contained space characters only, the tiddler
title is used for filtering.
}}}
For security reasons, if the TiddlyWiki is accessed from http, a ProxyService should be used to access an rssFeed from an other site.

[[news.php]] is an RSSFeed reader. It accesses an RSS 2.0 file and displays the feed in a page using a CSS.
The full syntax is :
>news.php[?[rss=<rssfile>[&css=<cssfile>]]
with :
*<rssfile>: a RSSFeed (default index.xml)
*<cssfile>: a CssFile (default embeded css)
Some examples :

|Options|##Configuration|
|Description|Show tiddlers one at a time with automatic permalink, or always open tiddlers at top/bottom of page.|
This plugin allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one tiddler displayed at a time.
!!!!!Documentation
>see [[SinglePageModePluginInfo]]
!!!!!Configuration
<<<
<<option chkSinglePageMode>> Display one tiddler at a time
><<option chkSinglePagePermalink>> Automatically permalink current tiddler
><<option chkSinglePageKeepFoldedTiddlers>> Don't close tiddlers that are folded
><<option chkSinglePageKeepEditedTiddlers>> Don't close tiddlers that are being edited
<<option chkTopOfPageMode>> Open tiddlers at the top of the page
<<option chkBottomOfPageMode>> Open tiddlers at the bottom of the page
<<option chkSinglePageAutoScroll>> Automatically scroll tiddler into view (if needed)
Notes:
* The "display one tiddler at a time" option can also be //temporarily// set/reset by including a 'paramifier' in the document URL: {{{#SPM:true}}} or {{{#SPM:false}}}.
* If more than one display mode is selected, 'one at a time' display takes precedence over both 'top' and 'bottom' settings, and if 'one at a time' setting is not used, 'top of page' takes precedence over 'bottom of page'.
* When using Apple's Safari browser, automatically setting the permalink causes an error and is disabled.

!Current research projects
Automated analaysis of team sports
A recent application area is the analysis of team sports, where players’ positions on the field are tracked with very high accuracy. Currently the trajectories are obtained automatically from 6-8 cameras around the field but all the annotation and analysis is performed manually. In this project the aim is to develop algorithms and software to completely automate this process. The project requires a mix of theory and programming.
Contact Joachim Gudmundsson or Thomas Wolle for details.
Geometric Networks
Geometric networks arise frequently in our everyday life: road networks, telephone networks, and computer networks are all examples of geometric networks that we use daily. They also play a role in disciplines such as VLSI design and motion planning. Almost invariably, the purpose of the network is to provide a connection between the nodes in the network. Often it is desirable that the connection through the network between any pair of nodes be relatively short. From this point of view, one would ideally have a direct connection between any pair of nodes. This, however, is usually unfeasible due to the costs involved, so one has to compromise between the quality and the costs of the connections.
The ratio of the "direct" distance between two given nodes and their distance in the graph is called the dilation (or, stretch factor) for the pair of nodes, and the dilation of a graph is the maximum dilation over all pairs of nodes. A graph with dilation t is also called a t-spanner. What one would like to have is a network that is a t-spanner for small t and that is not too costly. The goal of this project is to study such t-spanners.

Currently the trajectories are obtained automatically from 6-8 cameras around the field but all the annotation and analysis is performed manually. In this project the aim is to develop algorithms and software to automatically detect the most common ways the ball is transported from defence to an attacking player, either by detecting common sequences of players when an attack is built up or detecting frequent patterns of the balls trajectory (subtrajectory clustering). We will primarily use tools from the fields of algorithms, computational geometry and data mining. The project requires a mix of theory and programming.

title:
Improved Approximation Algorithms for Relay Placement
http://www.ams.sunysb.edu/~jsbm/papers/relays.pdf
Prof. Michiel Smid from Carleton University
title:
Spanning trees with O(1) average stretch factor
Abstract:
Let G be a connected graph in which each edge has a weight, and let T be a spanning tree of G. The stretch of two vertices p and q is the ratio of the the distance between p and q in T and the distance between p and q in G. In SODA 2007, Abraham, Bartal and Neiman showed that a spanning tree T exists such that the average stretch (over all (n choose 2) vertex pairs) is bounded by a constant.
I will prove this result for the case when G is the complete graph on a set of points in the plane, and the edge weights represent Euclidean distances.
Abstract:
What does it mean for two geometric graphs to be similar?
We propose a distance for geometric graphs that we show
to be a metric, and that can be computed by solving an integer
linear program. We also present experiments using a heuristic
distance function, and relate it to our metric.
Abstract:
Algorithms for determining quality/cost/price tradeoffs in saturated
markets are considered. In the model considered, a product is defined by
d real-valued qualities whose sum determines the unit cost of producing
the product. The optimization problem considers the following scenario:
given a set of n customers, each of whom has certain minimum quality
requirements and a maximum price they are willing to pay, the goal is to
design a new product and select a price for that product in order to
maximize the resulting profit.
An O(n log n) time algorithm is given for the case, d=1, of linear
products, and O(n(log n)^{O(d)}) time approximation algorithms are given
for products with any constant number, d, of qualities.
This is joint work with Michiel Smid and Joachim Gudmundsson
Gabriel graphs (Gabriel and Sokal 1969) and Yao graphs (Yao 1982) are two types of proximity graphs defined on a set of points in the plane. In recent years, these two graphs have found applications in (the theory of) wireless ad hoc networks. Gabriel graphs have been used in the design of guaranteed delivery routing protocols (Bose et al 2001, Karp and Kung 2000) while Yao graphs have been used in the design of power-efficient routing protocols (Li et al. 2001, Bahl et al. 2001).
In this talk we define Gabriel graphs and Yao graphs and sketch their applications to wireless networks. We then consider the maximum degree of any vertex in a Gabriel graph or a Yao graph. We show that for points uniformly distributed in a unit square, the maximum degree of any vertex is Theta(log n/log log n) with probability that tends to 1 as n tends to infinity.
In many traditional approaches, research has focused on data with `perfect precision'. However, data that is obtained from the real world has often a certain error or imprecision. For instance, a single `imprecise' point could be modelled by a disc.
For many applications areas it is important to measure the similarity between geometric objects. The Hausdorff distance is one way to measure such a similarity. The geometric objects we look at are two sets of imprecise points.
For a given measure and objects with imprecision, one of the simplest question one could ask is: What are the possible values of that measure for the imprecise objects?
Some results on the computation of the Hausdorff distance between imprecise point sets are presented. The focus is on a hardness result together with some theoretical background.
Abstract: Oblivious online routing (OOR) algorithms are suitable for the
applications with only local information to make routing decisions. This
paper presents two new OOR algorithms for Delaunay triangulations: the
Ellipse Routing algorithm and the Arc Routing algorithm. Both of their names
come from the shapes of their searching areas for a next-hop neighbor. This
paper also evaluates and compares the presented algorithms with three
existing OOR algorithms in terms of link distances and Euclidean distances.
The experimental results show that (1) the two new algorithms both perform
better than the other three OOR algorithms in terms of Euclidean distance,
but worse in terms of link distance and (2) Delaunay triangulations with
random node placement have the property that the shortest paths in link
distance metric and in Euclidean distance metric are discrepant in a large
proportion. Finally, this paper poses two interesting open problems based on
the experimental results.
Title: An introduction to Network Utility Maximization (NUM) theory
Papers: Frank Kelly's classical papers [[Rate control in communication networks: shadow prices, proportional fairness and stability|http://www.statslab.cam.ac.uk/~frank/rate.html]] and [[Charging and rate control for elastic traffic|http://www.statslab.cam.ac.uk/~frank/elastic.html]].
Title: Exploiting the broadcast nature of wireless
The papers to be presented:
ExOR: Opportunistic Multi-Hop Routing for Wireless Networks by Biswas & Morris, SIGCOMM 2005
XORs in the air: Practical Wireless Network Coding by Katti et al, SIGCOMM 2006
(Also in Transactions on Networking 16(3), 2008)
Title: Density Theorems for ~Right-Angle-Crossing graphs
Abstract: This seminar is motivated from two very diffent directions. The
first is from HCI: a series of human experiments by Weidong (Tony) Huang
have shown that edge crossings in a graph visualization do not inhibit
readability if they are at 90 degrees. The second is from the long
tradition of so-called "Turan-type problems" in combinatorial geometry:
such problems ask for the largest density of a geometric graph satisfying
certain constraints. The talk will describe recent results, jointly
obtained with Liotta and Didimo, on the density of geometric graphs in
which every crossing is at 90 degrees.
The theory of compressed sensing is about how to encode signals which are sparse or have a sparse representation in some basis and then decode them accurately (sometimes exactly) and efficiently. A key theorem is is that if the encoding matrix has the Restricted Isometric Property (RIP), which roughly means that the columns of the matrix are nearly orthogonal, and the signal is sufficiently sparse, then exact reconstruction is possible using L1-minimization. I will present a relatively new proof of this theorem by Baraniuk et. al. which uses the Johnson-Lindenstrauss lemma. Compressed Sensing is a rapidly developing area (see http://www-dsp.rice.edu/cs) and I will end with some observations and potential applications.
Correlated equilibrium, existence proof and algorithms through linear programming and primal-dual methods.
