In this study, we extended logic regression to longitudinal data with binary response and proposed “Transition Logic Regression Method” to find interactions related to response. In this method, interaction effects over time were found by Annealing Algorithm with AIC (Akaike Information Criterion) as the score function of the model. Also, first and second orders Markov dependence were allowed to capture the correlation among successive observations of the same individual in longitudinal binary response. Performance of the method was evaluated with simulation study in various conditions. Proposed method was used to find interactions of SNPs and other risk factors related to low HDL over time in data of 329 participants of longitudinal TLGS study.展开更多

For formalization of the description of interaction at a level of steps of the dialogue which is carried out in common by two spatially divided agents, the concept of synchronization of processes is analyzed. The approach to formalization of the description of conditions of synchronization when both the independent behaviour, and the communications of agents can be presented at a level of logic is offered. It is shown, that the collective behavior of agents can be described by the synthetic temporal logic that unite linear and branching time temporal logics.展开更多

Maneuvering patterns of the target are represented by model sets, including the constant velocity model （CA）, the Singer mode~, and the nearly constant speed horizontal-turn model （HT） in FIMM technology. The simulation results show that compared to conventional IMM, the reliability and real-time performance of underwater target tracking can be improved by FIMM algorithm.展开更多
