Generating placated random shapes for an area estimation study

Almowanes A., Kakiashvili T., Koczkodaj W. W.

Journal of Applied Mathematics and Computational Mechanics

2013

Vol. 12, nr 2

5--13

Random but visually nice shapes are often needed for cognitive experiments and processes. This study describes a heuristic for generating random but nice shapes. We call them placated shapes. These shapes are produced by applying the Gaussian blur to randomly generated polygons. Subsequently, the threshold is set to transform pixels to black and white from different shades of gray. This transformation produces placated shapes for easier estimation of areas. Randomly generated placated shapes are used for testing the accuracy of cognitive processes by pairwise comparisons. They can also be used in many other areas such as computer games or software testing. Such shapes could also be used for camouflaging heavy army equipment.

Supporting a Medical Diagnostic Process by Selected AI Methods : an Asperger Syndrome Case Study

Kakiashvili T., Koczkodaj W. W., Matheson D., Montgomery P., Passi K., Rybakowski F., Tadeusiewicz R., Woodbury-Smith M.

Studia Informatica : systems and information technology

2008

Vol. 1(10)

5--13

A medical knowledge-driven diagnostic process can be supported by AI methods as presented here by an Asperger Syndrome case study. Two methods: consistency-driven pairwise comparisons (CDPC) and automatic understanding (AU) are presented in this study. Deficiencies of a data-driven model for the medical diagnostic p rocess and clinical reasoning are also discussed.

Internet Contamination as a Global Harm and a Social Problem

Babiy V., Janicki R., Bigelow B., Grewal R. S., Kakiashvili T., Koczkodaj W. W., Passi K., Tadeusiewicz R.

This position paper demonstrates that the global and cumulative cost of dealing with spam is at the level of some natural disasters. Internet email has been a very powerful new technology with enormous social and scientific benefits. However, Internet contamination has currently become a serious social problem. In particular, email spam is a significant irritant and personal stressor which impairs quality of life. Technology solutions, such as filtering tools, are useful but imperfect as they are either too tight or too loose and require their own daily management. Spam volume has impaired daily operations of individual computers and causes servers to crash. It also threatens data integrity as important messages are often filtered along with the unwanted ones. Excessive Internet usage already can threaten mental health and the huge growth of spam only threatens to make the problem intolerable in the very near future. Spam is driven by profit. Social solutions, such as collective action, are needed as spam is a global threat and needs to be prosecuted as a serious threat to security.
