Due to the scarcity of license exempt spectrum at low frequencies, next generation multi-gigabit wireless communication will use 60 GHz. Propagation characteristics make impossible to use omnidirectional high-rate low-power transmission at long distances. As for directional transmission, it cannot be efficient with random channel access while the usage of deterministic one even in the state-of-the-art 60 GHz technologies --- e.g. IEEE 802.11ad --- raises a question of how much channel time shall be allocated for a stream to satisfy its QoS requirement. The main contribution of the paper is the mathematical model of Constant Bit Rate (CBR) flow transmission in IEEE 802.11ad networks, which allows to answer this question.
Creature questions of the mathematical, informational and programming support for the practice network community control are considered. Community mathematical model is proposed. This model utilization as basis for realization of the control system principal functions in the context of the participant interaction improvement and object community regions forming is considered.
We propose a new mathematical growth model of primary tumor and primary metastases which may help to improve predicting accuracy of breast cancer process using an original mathematical model referred to CoM-IV and corresponding software. The CoM-IV model and predictive software: a) detect different growth periods of primary tumor and primary metastases; b) make forecast of patient survival; c) have higher average prediction accuracy than the other tools; d) can improve forecasts on survival of BC and facilitate optimisation of diagnostic tests. The CoM-IV enables us, for the first time, to predict the whole natural history of primary tumor and primary metastases growth on each stage (pT1, pT2, pT3, pT4) considering only on primary tumor sizes. Summarising: CoM-IV a) describes correctly primary tumor and primary distant metastases growth of IV (T1-4N0-3M1) stage with (N1-3) or without regional metastases in lymph nodes (N0); b) facilitates the understanding of the appearance period and manifestation of primary metastases.
