a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
با پیشرفت و همگانی شدن کامپیوترها، نیاز برای انتقال داده به کامپیوترها افزایش پیدا کرد. پورت ها وسیله ای برای ارتباط با device های جانبی متنوع از جمله کیبورد، میکروفون و ... هستند. با گذشت زمان پورتها به منظور پشتیبانی از گستره وسیعی از device ها، پیشرفته تر و کابردی تر شدند. با روی کار آمدن پورت usb دراواسط دهه 1990، این پورت توانست جایگزین سایر پورت های موجود شود چراکه این پورت ها به تنوع نا...
in this paper the optimal design of a dissipator made of aluminium and steel and principallysubjected to shear forces and the preliminary results of the characterization tests are described.the device has been designed on the basis of an optimization procedure with the objective tomaximize the energy dissipated in the device. the response of a 3d frame equipped with thedevice and subjected to 7...
multiwall carbon nanotubes (mwcnts) are grown via chemical vapour deposition method directly on a stainless steel substrate. raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. after their removal from the stainless steel substrate, the as-grown mwcnts are then a...
This paper presents a platform for power autonomous wireless energy meter device using piezoelectric energy harvesters. This device can be mainly used for measuring the share of heat energy consumption in a fair manner in building complex with central heat energy system. In the suggested device, the piezoelectric energy harvester is also used as a flow-meter to reduce the power consumption of t...
