| 1 | Discrete-time based sliding-mode control of robot manipulators显示文摘Purpose-The purpose of this paper is to develop sliding mode control with linear and nonlinear manifolds in discrete-time domain for robot manipulators.Design/methodology/approach–First,a discrete linear sliding mode controller is designed to an n-link robot based on Gao’s reaching law.In the second step,a discrete terminal sliding mode controller is developed to design a finite time and high precision controller.The stability analysis of both controllers is presented in the presence of model uncertainties and external disturbances.Finally,sampling time effects on the continuous-time system outputs and sliding surfaces are discussed.Findings–Computer simulations on a three-link SCARA robot show that the proposed controllers are robust against model uncertainties and external disturbance.It was also shown that the sampling time has important effects on the closed loop system stability and convergence.Practical implications-The proposed controllers are low cost and easily implemented in practice in comparison with continuous-time ones.Originality/value-The novelty associated with this paper is the development of an approach to finite time and robust control of n-link robot manipulators in discrete-time domain.Also,obtaining an upper bound for the sampling time is another contribution of this work. | Sajjad Shoja Majidabad Heydar Toosian Shandiz | 2012 | International Journal of Intelligent Computing and Cybernetics2012，5，3： | 2 |

| 11 | Evaluation of imatinib mesylate(Gleevec) on KAI1/CD82 gene expression in breast cancer MCF-7 cells using quantitative real-time PCR显示文摘Objective: To evaluate the effect of imatinib mesylate on cell viability, anti cancer effect through modulation of KAI1/CD82 gene expression in breast cancer MCF-7 cell line.Methods: The effects of imatinib mesylate on cell viability in MCF-7 cell line were assessed using MTT assay and IC_(50) value was determined. GAPDH and KAI1/CD82 were selected as reference and target genes, respectively. Quantitative real time PCR technique was applied for investigation of KAI1/CD82 gene expression in human breast cancer MCF-7 cells. Subsequently, the quantity of KAI1 compared to GAPDH gene expressions were analyzed using the formula; 2^(-DDCt).Results: Imatinib was showed to have a dose-dependent inhibitory effect on the viability of MCF-7 cells. CD82/GAPDH gene expression ratios were 1.322 ± 0.030(P > 0.05),2.052 ± 0.200(P < 0.05), 2.151 ± 0.270(P < 0.05) for 10, 20 and 40 mmol/L of imatinib concentrations.Conclusions: Based on the present data, imatinib mesylate might modulate metastasis by up-regulating KAI1/CD82 gene expression in human breast MCF-7 cancer cell line. | Seyed Ataollah Sadat Shandiz Marjan Khosravani Sepideh Mohammadi Hassan Noorbazargan Amir Mirzaie Davoud Nouri Inanlou Mojgan Dalirsaber Jalali Hamidreza Jouzaghkar Fahimeh Baghbani-Arani Behta Keshavarz-Pakseresht | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，2： | 1 |
