Introduction: There are many similarities between memory impairment in patients suffering from Alzheimer and animals treated by Cannabinoids. The agonists of Cannabinoid receptors affect on a variety of memories and leanings. The present study aims to investigate the role of α-1-adrenergic receptors in central region of amygdala in state-dependent learning induced by WIN55,212-2 (cannabin...

In this paper, the characteristics of the typical two models of parallel genetic algorithms are compared. Those models are the coarse grained model and the micro grained model. Especially, the parallel efficiency and the total calculation time on PC clusters that are build with commodity hardware are examined. The characteristics are examined through the numerical examples. There are two major ...

The parallel mechanism has become an alternative solution when micro manipulators are demanded in the fields of micro manipulation and micro assembly. In this paper, a threeDegree-Of-Freedom (3-DOF) parallel micro manipulator is presented, which is directly driven by three micro gas bubbles. Since the micro gas bubbles are generated and maintained due to the surface tension between the gas and ...

This paper examines the blood chamber of a left ventricular assist device (LVAD) under static loading conditions and standard operating temperatures. The LVAD’s walls are made of a temperature-sensitive polymer (ChronoFlex C 55D) and are covered with a titanium nitride (TiN) nano-coating (deposited by laser ablation) to improve their haemocompatibility. A loss of cohesion may be observed near t...

Electro active polymers (EAPs) exhibit large electrically induced strains (bending or stretching) with electrical stimuli. EAPs are utilized as actuators in micro gripper and micromanipulator in micro robotics activities. Remote center compliance (RCC) based micro gripper is developed to facilitate insertion of peg-in-hole (PIH) for micro assembly operations. An effect of RCC compliance during ...

waterwheels are the oldest types of hydraulic machines. these turbines are of relatively simple design, large diameter, low rotational speed and high torques. but applying them as micro hydros of high speed and small diameter is yet to be explored. a micro hydro waterwheel of one meter diameter was designed and manufactured at the iranian  esearc†h organization for science and technology (irost...

On the basis of discussing the information spreading mechanism under Internet environment, we have studied on how to build a public opinion monitoring model according to the semantic content or text mining in recent years. A micro-blog public opinion corpus named MPO Corpus on the content of micro-blog information as a test data set has been constructed by our research team. In this paper, it p...

We present in this paper the findings of a study on the role of macroadaptation in conversational intelligent tutoring. Macro-adaptivity refers to a system’s capability to select appropriate instructional tasks for the learner to work on. Micro-adaptivity refers to a system’s capability to adapt its scaffolding while the learner is working on a particular task. We compared an intelligent tutori...
