Can a falling ball lose speed?
Paulo Murilo Castro de Oliveira, Suzana Moss de Oliveira, Felipe Augusto Pereira +1
A small and light polystyrene ball is released without initial speed from a certain height above the floor. Then, it falls on air. The main responsible for the friction force again…
Bit-strings and other modifications of Viviane model for language competition
P. M. C. de Oliveira, D. Stauffer, F. W. S. Lima +3
The language competition model of Viviane de Oliveira et al is modified by associating with each language a string of 32 bits. Whenever a language changes in this Viviane model, al…
Phase transition in a mean-field model for sympatric speciation
V. Schwämmle, K. Luz-Burgoa, J. S. Sá Martins +1
We introduce an analytical model for population dynamics with intra-specific competition, mutation and assortative mating as basic ingredients. The set of equations that describes…
Positive mutations and mutation-dependent Verhulst factor in Penna ageing model
S. Moss de Oliveira, D. Stauffer, P. M. C de Oliveira +1
We twice modify the Penna model for biological ageing. First we introduce back (good) mutations and a memory for them into the model. It allows us to observe an improvement of the…
Simulating Male Selfish Strategy in Reproduction Dispute
P. M. C de Oliveira, S. Moss de Oliveira
We introduce into the Penna Model for biological ageing one of the possible male mechanisms used to maximize the ability of their sperm to compete with sperm from other males. Such…
Bit-String Models for Parasex
S. Moss de Oliveira, P. M. C. de Oliveira, D. Stauffer
We present different bit-string models of haploid asexual populations in which individuals may exchange part of their genome with other individuals (parasex) according to a given p…
