Lithium-ion secondary batteries are commonly used in electric vehicles, smart phones, personal digital assistants (PDA), notebooks and electric cars. These lithium-ion secondary batteries must charge and discharge rapidly, causing the interior temperature to rise quickly, raising a safety issue. Over-charging results in an unstable voltage and current, causing potential safety problems, such as...

This article presents a system level model of carbon nanotube (CNT) based mechanical sensor, which consists of micro-electro-mechanical (MEMS) platform that is served to actuate single-axis force and single CNT is placed between the movable and fixed electrodes. The change in conductivity of CNT, when strain is applied, is used to measure force or displacement. The simulation of the whole senso...

Micro reformers still face obstacles in minimizing their size, decreasing the concentration of CO, conversion efficiency and the feasibility of integrated fabrication with fuel cells. By using a micro temperature sensor fabricated on a stainless steel-based micro reformer, this work attempts to measure the inner temperature and increase the conversion efficiency. Micro temperature sensors on a ...

In this paper we introduce a two-sided Arnoldi method that can be used in the reduction of high order systems, based on a two-sided Krylov subspace approach. The presented method can find better results than the well known Arnoldi algorithm and leads to the same reduced models as the (numerically unstable and more complicated) Lanczos algorithm. The new algorithm can find two orthogonal bases f...

For the testing of micro electro-mechanical systems, we propose a taxonomy built-in self-testing methods. These solutions that are non-intrusive, cost-effective and typically non-intrusive during process being actively sought after as cost micro-electro-mechanical systems (MEMS) can account for 50% total end product. The selection methods is analyzed extensively, classification table such prese...
