The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...

Three major approaches have been developed to predict outcomes for concerted reactions controlled by orbital symmetry analysis using (i) correlation diagrams1, (ii) frontier orbital interactions in transition states2 and (iii) incipient aromatic/ antiaromatic character in transition states3-5. The latter approach (Zimmerman-Dewar or Hückel-Möbius) is particularly simple to teach to undergraduat...

در حال حاضر چندین روش برای اندازه گیری چربی زیرپوستی بدن در حوزه های بالینی وجود دارد ، مانند : magnetic resonance imaging(mri)، (computer tomography(ct، ultrasound imaging(us) ، dual energy x-ray absorptiometry(dexa). این روش ها بطور وسیعی در حوزه های بالینی به عنوان وسایل دقیق و مفید ، مورد استفاده قرار می گیرند. به هر حال این روش ها محدودیت های زیادی مانند هزینه بالا و یا خطر تابش اشعه را دا...

The power system nonlinearity and its profound impact on the individual states of power system is first evaluated and the interaction between their constituent modes during the occurrence of internal mode resonance (IMR) is discussed in this paper. A typical dynamical feature of nonlinear systems is the frequency-energy dependence of their states and their corresponding constituent modes which ...

A lower vacuum housing (34) of a sensor dewar (26) is fabricated in a single brazing operation from ceramic and metallic components. The components are assembled with ceramic-to-metal interfaces and metal-to-metal interfaces. Brazing is accomplished by active brazing of the ceramic­ to-metal interfaces and non-active brazing of the metal-to­ metal interfaces. Specific combinations of active bra...
