The Logistic model and simulation algorithms in the ecological species were introduced to analyze the remote collaborative structure of weapons model development and the equilibrium and stability condition of its mode. The weapons development remote collaborative structure was designed, and two collaborative logistic models of the model development was built as “O—A” and “A—A”. The stability co...

This work explores a novel approach to the analysis and modelling of computer supported collaborative writing. The aim of this dynamic modelling approach is to capture the structure of user behaviour as they interact with a computer system. Markov chains models are derived from the empirical data on the use of the system. These models are compared so as to highlight how the dynamic structure of...

This study investigated the comparative effects of audio-visually prompted collaborative dialogue on the listening comprehension development of symmetrical, asymmetrical, and asymmetrical teacher-fronted EFL learner groups. Besides, it explored the attitude of the participants of the groups concerning the effectiveness of collaborative dialogue for their listening comprehension improvement. The...

conclusions the growth rate of information in bioinformatics databases could facilitate studies of live organisms prior to observation studies. two different protein classes could be causative agents of one disease. however, two related diseases from one disease group could consist of different protein classes. future research in the field of proteomics could allow modern insight to reshuffling...

recommender systems (rs) provide personalized recommendation according to user need by analyzing behavior of users and gathering their information. one of the algorithms used in recommender systems is user-based collaborative filtering (cf) method. the idea is that if users have similar preferences in the past, they will probably have similar preferences in the future. the important part of col...

Professional interactions among health providers are critical to an efficient shared-care model. This research investigates whether the collaborative structure between general practitioners and specialists affects either the health status of patients or their pharmacy costs. The more concentrated collaborative structure results in lower pharmacy costs, but not in higher patient.
