Passive and semi-active heave compensator: Project design methodology and control strategies
Heave compensator is a system that mitigates transmission of heave movement from vessels to the equipment in the vessel. In drilling industry, a heave compensator enables drilling in offshore environments. Heave compensator attenuates movement transmitted from the vessel to the drill string and drill bit ensuring security and efficiency of the offshore drilling process. Common types of heave co...
متن کاملStrategies for Control of Pandemic Influenza: Active and Passive Immunization
s S5 modulate antigenicity and receptor binding, confounds retrospective analysis of genetic variation in HA. The situation is complicated further by the occurrence of epistatic changes within HA and between HA and NA to maximizeviral fitness following selection. Moreover, substitutions selected to modulate receptor avidity will inevitably modify receptor specificity for various sialic acid ter...

تاثیر منبع کنترل رفتار بر روی موفقیت تحصیلی زبان آموزان انگلیسی بندرت در ایران ارزیابی شده است. هدف این تحقیق ارزیابی رابطه بین منبع کنترل رفتار زبان آموزان انگلیسی و موفقیت آنها در مهارت های خواندن و نوشتن زبان انگلیسی است. محقق همچنین رابطه بین منبع کنترل رفتار و راهبردهای یادگیری زبان انگلیسی را در این تحقیق جستجو می کند. بدین منظور محقق ابتدا نسخه فارسی پرسشنامه منبع کنترل رفتار (duttweiler...
15 صفحه اولControl Processes Optimization for Mechanical Systems with Active, Semi-Passive and Passive Actuators
The influence of the geometric parameters of two-link manipulator on the energy expenditure necessary for the implementation of a given movement is investigated. It is proposed approximation-compensatory approach to replace the active actuators in the joints of the manipulator on semi-passive and entirely passive actuators. Advantages and disadvantages of such replacement are analyzed and the f...
متن کاملActive Suspension Control of Ground Vehicle Heave and Pitch Motions
Ride quality depends on a combination of vertical displacement (heave) and angular displacement (pitch). Road irregularities are the main factor affecting ride comfort. Suspension elements between the road wheels and the vehicle body generate vertical forces which excite both heave and pitch motions. An active controller design based on time-scale separation and an "input decoupling transformat...
