gait contains important information about the status of the human body and physiological signs. in many medical applications, it isimportant to monitor and accurately analyze the gait of the patient. since walking shows the reproducibility signs in several phases,separating these phases can be used for the gait analysis. in this study, a method based on image processing for extracting phases of...

The spread of Spartina alterniflora (smooth cordgrass) has put biodiversity and ecosystem function at risk since it was introduced to China just a few decades ago. A better understanding how the range S. will expand in future help manage invasion this species coastal wetlands. However, is difficult model extent saltmarshes China. To address issue, we combined multi criteria evaluation with trad...

A new wireless medium access control scheme is proposed for implementing collaborative codes on the carrier sense multiple access with collision avoidance (CSMA/CA) protocol. To simplify the analysis, a new backoff algorithm is suggested that is simple to implement and to model. Markov chain analysis is used for modelling the proposed CC-CSMA/CA protocol. The resulting model describes the regul...

in this paper semi-markov models are used to forecast the triple dimensions of next earthquake occurrences. each earthquake can be investigated in three dimensions including temporal, spatial and magnitude. semi-markov models can be used for earthquake forecasting in each arbitrary area and each area can be divided into several zones. in semi-markov models each zone can be considered as a state...
