Computational techniques are described for the automorphism groups of edge-weighted graphs. Fortran codes based on the manipulation of weighted adjacency matrices are used to compute the automorphism groups of several edge-weighted graphs. The code developed here took 37l/2 min of CPU time to generate 1 036 800 permutations in the automorphism group of an edge-weighted graph.

This study is an ethical analysis of the Global Positioning System (GPS) in the context of taxi business, i.e. it is an attempt to investigate the ethical consequences of installing GPS in taxis. The reason for installing GPS in taxis was to increase the taxi drivers’ security, but there are other effects of the installation as well. When the stakeholders that are possibly affected by the techn...

This paper presents an alternative approach for estimating task complexity. Construction of a self-organizing neural tree structure, following the paradigm “divide and rule”, requires knowledge about task complexity. Our aim is to determine complexity indicator function and to hallmark its’ main properties. A new approach uses IBM © Zero Instruction Set Computer (ZISC-036 ®) and applies for a r...

OBJECTIVE To compare postoperative respiratory and swallowing functions between patients who underwent classic supracricoid laryngectomy (SCL) and those who underwent SCL with laryngeal reconstruction using the sternohyoid muscle. STUDY DESIGN Prospective study. SETTING National cancer center. SUBJECTS AND METHODS Forty-four patients who consecutively underwent SCL for laryngeal squamous ...
