Constructing and Understanding New and Old Scales on Slide Rules
Istvan Szalkai, Ace Hoffman
We discuss the practical problems arising when constructing any (new or old) scales on slide rules, i.e. realizing the theory in the practice. This might help anyone in planning an…
On the General Shape of Scales on Slide Rules
Istvan Szalkai
We give a thoroughful explanation of the general properties of different, general scales, corresponding to different (all possible) mathematical functions f(x), we mention and anal…
On Contact Numbers of Finite Lattice Sphere Packings of 20-27 Balls
Istvan Szalkai
Empirical constructions having maximal contact numbers of unit balls as putative best ones are presented for 20-27 balls.
Online Algorithms for a Generalized Parallel Machine Scheduling Problem
Istvan Szalkai, Gyorgy Dosa
We consider different online algorithms for a generalized scheduling problem for parallel machines, described in details in the first section. This problem is the generalization of…
