The variation of vacuum level inside a field emission device when electron is emitted from multi-walled carbon nanotubes (MWCNTs) by electric field was measured where MWCNT gauge packaged with a vacuum device was used to measure the degree of a vacuum until the end of the vacuum device life. It was found that the electrical properties of MWCNTs altered with the degree of a vacuum. We fabricated...
Temperature variations are one of the most crucial factors that need to be compensated for in MEMS sensors. Many traditional methodologies require an additional circuit compensate temperature. This work describes a new active temperature compensation method capacitive strain sensors without circuits. The proposed is based on complement 2-D structure design. It consumes zero-power, which essenti...
Mid-infrared laser ablation of water-rich targets at the maximum of the 2.94 μm absorption band is a two-step process initiated by phase explosion followed by recoil pressure induced material ejection. Particulates and/or droplets ejected by this high temperature high pressure process can be ionized for mass spectrometry by charged droplets from an electrospray. In order to gauge the internal e...

در این پژوهش ساختار جدیدی یرای تغییردهنده ی فاز با استفاده از تکنولوژی mems ارائه می شود. ساختار ارائه شده ی جدید از ترکیب دو روش رایج موجود برای تغییردهنده ها ی فاز شکل می گیرد که سبب می شود محدودیت های حجم اشغالی بالا و عدم توانایی شیفت فاز بزرگ در فرکانس های پایین که هریک به ترتیب مربوط به روش سوئیچ لاین و dmtl می باشد، برطرف شود و همچنین ساختار دارای قابلیت عملکرد در چند باند فرکانس...
We introduce a quantale-valued generalization of approach spaces in terms of quantale-valued gauges. The resulting category is shown to be topological and to possess an initially dense object. Moreover we show that the category of quantale-valued approach spaces defined recently in terms of quantale-valued closures is a coreflective subcategory of our category and, for certain choices of the qu...
