Pneumatic active suspension system for a one-wheel car model using fuzzy reasoning and a disturbance observer

This paper presents the construction of a pneumatic active suspension system for a one-wheel car model using fuzzy reasoning and a disturbance observer. The one-wheel car model can be approximately described as a nonlinear two degrees of freedom system subject to excitation from a road profile. The active control is composed of fuzzy and disturbance controls, and the active control force is constructed by actuating a pneumatic actuator. A phase lead-lag compensator is inserted to counter the performance degradation due to the delay of the pneumatic actuator. The experimental result indicates that the proposed active suspension improves much the vibration suppression of the car model.

Counselling and demand-driven adult learning

This paper advocates various rolesfor counselling in order to promote lifelong adultlearning. Demand-driven adult learning underlines theimportance for counsellors to recognize the widediversity that is evident in adult learning. The paperargues that counselling for adults must fully takeinto consideration adult learners' psycho-socialdemands and economic realities: the need for adults tolearn throughout life, the economic contributions ofunpaid work by adults, and the sense of socialresponsibility manifested by adult learners.Counselling faces formidable challenges when assistingthe adult learning process: learner-focusedinformation services, psychological techniques tostimulate and support adult learning, a self-efficacyapproach to adult learning, a gender-sensitiveapproach to adult learning, support for workplaceadult learning activities, school violence managementby adults, an active and productive approach toageing, intergenerational learning, and psycho-socialmeasures to remove barriers to adult learning.

Kenya 1975‐1995: an introductory note on educational expansion

Expanding school enrolment in Kenya was given the highest priority in the leverage of development. The number of pupils has grown from 2.9 to 5.56 million in the 20 years since 1975. There has been a similar expansion at the secondary level. And the expansion at the university level has been even faster, which is more than four times than that in 1984/85. But still the increase in enrolments was not enough to absorb pent‐up demand. The female enrolment has significantly improved, and female teachers constitute 39.5% of the total number of teachers. The imbalance is vast between the educational supply and economic demand (employment). The question is whether the growth can be maintained; whether it is enough.     

Active suspension control of a one-wheel car model using single input rule modules fuzzy reasoning and a disturbance observer

INTRODUCTION Research and development of active suspensionsystems for car models are increasing much in recentyears because the active suspension systems offergood riding comfort to passengers of high speedground transportation. Investigation of linear activesuspension systems has been mainly developed basedon optimal control theory assuming that the car modelis described by a linear or approximately linear sys-tem (Hác, 1986; Hrovat, 1993; Yoshimura and Su-gimoto, 1990).
