Modeling and Motion Control of Underwater Snake Robot by Peijuan LI, Gang YANG, Tiezheng GUO, Yang LU

“…A kinematic model was established based on the snake motion mechanism, and a motion control method based on fuzzy control and a central pattern generator(CPG) was proposed. The CPG model was constructed by several Hopf oscillators with double-coupled chain network structure after the stability analysis of the limit cycle in a single Hopf oscillator model, and a fuzzy controller and the CPG model were introduced to form a closed-loop control network. …”

Computed Tomography Scan and Clinical-based Complete Response Prediction in Locally Advanced Rectal Cancer after Neoadjuvant Chemoradiotherapy: A Machine Learning Approach by Seyyed Hossein Mousavie Anijdan, Daryush Moslemi, Reza Reiazi, Hamid Fallah Tafti, Ali Akbar Moghadamnia, Reza Paydar

“…According to the modeling based on combined clinical and radiomics data together, area under the curves for the nonresponders and complete respond group (responder group) was 0.97 and 0.99, respectively. Conclusion: Random forests modeling based on combined radiomics and clinical characteristics of the pretreatment tumor images has the ability to predict the response or non-response to neoadjuvant treatment in LARC to an acceptable extent.…”
