Inelastic interaction and splitting of strain solitons propagating in a rod
The results of original research of the soliton interaction and the interaction of solitons
with a boundary of a rod are presented in this paper. Moreover, the paper contains a brief
analytical review of publications devoted to the theoretical study of the formation and
peculiarities of propagation of longitudinal strain solitons in nonlinearly-elastic rods, as
well as publications devoted to the experimental detection of such waves.
We consider an application of power indices, which take into account preferences of agents for coalition formation proposed for an analysis of power distribution in elected bodies to reveal most powerful (central) nodes in networks. These indices take into account the parameters of the nodes in networks, a possibility of group influence from the subset of nodes to single nodes, and intensity of short and long interactions among the nodes.
The article summarizes results of a mail survey and face-to-face interviews carried in 2016 among the directors of medium-size fast-growing Russian high-tech companies aimed at analysis of intensity, directions, forms, problems and prospects of their cooperation with higher education institutes. Data from 155 questionnaires was complimented with the 15 deep interviews demonstrates that companies prefer to interact with universities in educational sphere while they are most satisfied with their joint research. One of the serious problems is lack of qualification among the university professionals. Despite some problems, the majority of surveyed companies plan to expand their cooperation with higher educational institutes. The surveyed companies believe that the government may help to facilitate university— industry cooperation proposing various financial instruments.
This paper attempts to model network dynamics of MOOC discussion interactions. It contributes to providing alternatives to conducting null hypothesis significance testing in educational studies. Using data collected from two successive psychology MOOCs in 2014 and 2015, the probabilistic longitudinal network analysis was performed by employing stochastic actor-based models with statistical accuracy. Understanding the mechanisms that drive the dynamics of discussions shed light on the design of a self-generated and learner-supported learning environment to meet the challenges of accommodating a massive and global student body.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
