Pantelis Rodis: On the computability of causal inference
http://pantelisrodis.blogspot.com/2015/04/on-computability-of-causal-inference.html
A blog about Computer Science and Programming. Friday, 3 April 2015. On the computability of causal inference. Causation (or else causality) refers to the cause-effect relation that may exist between two events or phenomena. The causal inference problem regards the determination of causation between events. Let’s formulate the general case of the causal inference problem as a decision problem. Let A. Be two sets of data. CAUSAL = { A. There is computable function f. Then there is function f. This describ...

Pantelis Rodis: Against the idea of a computable universe
http://pantelisrodis.blogspot.com/2015/10/against-idea-of-computable-universe.html
A blog about Computer Science and Programming. Friday, 9 October 2015. Against the idea of a computable universe. The computable universe hypothesis, states that every operation and phenomenon in the universe is computable. So if you can describe all the phenomena in state s 1. Of some part of the universe (or of the whole universe), then you can compute the physical operations in any state s i. That is a successor of s 1. To any state s i. Any not trivial system of logic is incomplete. This is a ver...

A blog about Computer Science and Programming. Saturday, 29 October 2016. Zombies and other freaks in GIS workplaces. In the past, in certain jobs and certain offices I had the sense that I was surrounded by zombies and freaks. It seems I 'm not the only one to have had such experiences. Read this post. By geobreadbox.com which I can't decide if it is funny or horrifying serious. Http:/ www.geobreadbox.com/blog-1/2016/10/27/53-geospatial-friday-halloween-special. Subscribe to: Post Comments (Atom).

Pantelis Rodis: June 2016
http://pantelisrodis.blogspot.com/2016_06_01_archive.html
A blog about Computer Science and Programming. Saturday, 25 June 2016. The way in which players navigate the game will help researchers to understand the mental process of 3D navigation, which is one of the first skills lost in dementia. It is hoped that a large number of people will play the game, thus contributing much more data than could easily be obtained in a laboratory experiment. Find it in Google Play. There is also a greek version. Sunday, 5 June 2016. It is safe to consider a description that ...

Pantelis Rodis: System security as a computational problem
http://pantelisrodis.blogspot.com/2015/06/system-security-as-computational-problem.html
A blog about Computer Science and Programming. Friday, 26 June 2015. System security as a computational problem. In this post I talk about system security and I examine it as a computational problem. The motivation of thinking about this came from a very interesting post. By Dick Lipton and Ken Regan that was published on their blog. A few days ago. The problem of developing a secure system regards the development of a system that will maintain a set of information F. As a set of strings and w. Then the ...

Pantelis Rodis: Synchronizing zoom and pan among multiple map tiles using OpenLayers
http://pantelisrodis.blogspot.com/2015/03/synchronizing-zoom-and-pan-among.html
A blog about Computer Science and Programming. Monday, 16 March 2015. Synchronizing zoom and pan among multiple map tiles using OpenLayers. What can you do if you have more than two or more maps in a html page and you want to synchronize their pan and zoom, so they all show the same location, at the same scale, each time you look at them? Div style="width:100%; height:50%" id="map" /div. Map1 = new OpenLayers.Map('map', options);. Map2 = new OpenLayers.Map('map', options);. Map1setCenter( new OpenLayers&...

Pantelis Rodis: January 2016
http://pantelisrodis.blogspot.com/2016_01_01_archive.html
A blog about Computer Science and Programming. Thursday, 28 January 2016. Geometry and randomness reduction. Think of a 2-dimensional space, say a piece of paper. Let’s call it d. Is random on the sense that on there is nothing special about p. In comparison with any other point in d. Now let us define arbitrarily in d. A coordinate system and place in some point that we also choose arbitrarily coordinates (0, 0). Based on our coordinate system and its metrics the points in d. Or else algorithmic complex...

A blog about Computer Science and Programming. Wednesday, 24 August 2016. Maps are better displayed on big (TV) screens. TV sets these days have become more powerful than ever. They are equipped with powerful operating systems like Android and WebOS and their screens seem more magnificent than they could ever be. So why not to use them for map display? To Android TV and Amazon TV. The result is really great try it. Subscribe to: Posts (Atom). The illegal and misleading practices of mobogenie.com. In this...

Pantelis Rodis: How to reduce a spatial problem to an easier one
http://pantelisrodis.blogspot.com/2014/05/how-to-reduce-spatial-problem-to-easier.html
A blog about Computer Science and Programming. Thursday, 1 May 2014. How to reduce a spatial problem to an easier one. The reduction of the computation of a problem A. To the computation of an easier problem B. Is a traditional method of building a more efficient algorithm for the resolution of A. Especially useful when A. Is computationally hard. This method is efficient when it comes to spatial analysis and spatial query problems. In a dataset E. With some other set of objects S’. In dataset E’. Analyz...
