Passive, active and intra-active (self) touch.
A series of experiments are described in which magnitude estimates of the perceived size of steel balls were made when the balls were actively rolled between the fingertip and several other body sites (thumb, thenar eminence, forearm). This movement, called scripting, involves actively moving an object by a touching surface over another surface of the body which is passively being touched. We d...
متن کاملThe Effects of Cooperative Language Learning Strategies on Learning Active and Passive Structures among Iranian EFL Learners
This study aims at investigating the effects of cooperative language learning on learning active and passive structures among Iranian EFL students. The participants of the study were 60 high school students that were selected from third grade of Barikbin high school in Qazvin. All of the participants were male. Their level of proficiency was intermediate. Then the participants were divided into...

اغلب تحقیقات انجام شده در حوزه ی " یادگیری مشارکتی " نشان ازتاثیرات مثبت آن بر موفقیت تحصیلی ، افزایش دانش و توانش زبانی، انگیزه ، تعاملات میان دانش آموزان(مهارتهای گروهی و پذیرش افراد با سطح درسی ضعیفتردر گروه)، و هم چنین علاقه به محیط آموزشی دارد .البته لازم به ذکر است که تحقیقاتی هم حاکی از عدم تاثیر این نوع یادگیری وجود دارد. بر اساس این پیشینه ، پژوهش حاضر به بررسی تاثیر "مدل یادگیری با هم...
15 صفحه اولVibration Reduction and Performance Enhancement of Helicopter Rotors Using an Active/Passive Approach
Active/passive optimization of helicopter rotor blades for vibration reduction and performance enhancement at high advance ratios is studied. Dynamic stall is the dominant source of high vibration levels for this flight regime. In the active/passive approach, active control of vibration and required rotor power is implemented with partial span trailingedge flaps operating according to a closed-...
متن کاملMaximum velocity of self-propulsion for an active segment
The motor part of a crawling eukaryotic cell can be represented schematically as an active continuum layer. The main active processes in this layer are protrusion, originating from non-equilibrium polymerization of actin fibers, contraction, induced by myosin molecular motors and attachment due to active bonding of trans-membrane proteins to a substrate. All three active mechanisms are regulate...
