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...

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...

many studies on cold environments have been developed over the past two decades. highmountain freshwater presents high variability of nutrients and chemico-physical parameters, showing variations of ph, oxygen concentration, metals and temperature throughout the year. national park of sierra nevada (granada, spain) (37°032 n 03°182 w), has almost 40 lakes that are reported to be both endemic an...

en 1994, 125 carcases of camel (100 from isfahan and 25 from yazd) in slaughter - houses were studied for parasitic infections. seventy percent of the camels were infected with hydatid cyst and half of the males (50%) had testicular filaria identified as dipetalonema evansi. all the infected male camels except 3, demonstrated sheathed rnicrofilariae in their peripheral blood smears. although so...

the micro wire electrical discharge machining (micro wire-edm) process is a modern machining process with various applications in manufacturing micro-parts. the recast layer remaining on the machined surfaces is an inevitable complication of this process. this layer can subsequently affect the machined parts performance. to optimize the recast layer in the micro wire-edm of the molybdenum micro...

......This special issue represents the fifth anniversary of an important tradition in the computer architecture community: IEEE Micro’s Top Picks from the Computer Architecture Conferences. This tradition, initiated by IEEE Micro’s former Editor in Chief, Pradip Bose, attempts to share with the IEEE Micro readership a sampling of the top papers published in computer architecture in the past ye...

Mechanical testing of materials at the microscales is challenging. It requires delicate procedures not only for producing and handling the specimen to be tested, but also for applying an accurate and controlled force. This endeavor is even more challenging when it comes to investigating the behavior of brittle materials such as glass. Here, we present a microtensile tester for investigating sil...
