A high sensitivity field asymmetric ion mobility spectrometer (FAIMS) was designed, fabricated, and tested. The main components of the system are a 10.6 eV UV photoionization source, an ion filter driven by a high voltage/high frequency n-MOS inverter circuit, and a low noise ion detector. The ion filter electronics are capable to generate square waveforms with peak-to-peak voltages up to 1000 ...

bilateral synchronous male breast cancer is very rare. a 63-year-old male presented with rapidly progressive enlarging bilateral breast masses without ulceration and bloody nipple discharge. synchronous bilateral breast cancer was diagnosed by fine needle aspiration cytology. pathology study revealed grade 2 invasive ductal carcinoma in both breasts. he underwent a bilateral modified radical ma...

this article presents a fuzzy robust mixed - sensitivity gain - scheduled h controller based on the loop -shaping methodology for a class of mimo uncertain nonlinear time - varying systems. in order to design this controller, the nonlinear parameter - dependent plant is first modeled as a set of linear subsystems by takagi and sugeno’s (t - s) fuzzy approach. both loop - shaping methodology and...

To reduce the amount of data transfer in networked control systems and wireless sensor networks, measurements are usually taken only when an event occurs, rather than at each synchronous sampling instant. However, this complicates estimation and control problems considerably. The goal of this paper is to develop a state estimation algorithm that can successfully cope with event based measuremen...

A comparison is considered of the experimentally obtained impedance locally reacting acoustic liner samples with calculated using semi-empirical Goodrich, Sobolev and Eversman models. The models are outlined. In experiment, synchronously measured on a normal incidence tube by transfer function method Dean’s method. modification conventional proposed to obtain these measurements. To automate mea...

This paper describes our current study in the development of collaborative design environment which considers ICT (Information and Communication Technology) and architectural space. Our study group has been developing a computerized prototype environment for collaboration, which attempts to support synchronous design collaboration in a continuously connected project-room at distributing sites. ...

A method is described for obtaining the rate constant of the photodegradation process of fluorophores illuminated by a focused laser beam. The explicit kinetic equations, describing the population dynamics of excited singlet and triplet states, are averaged over the illuminated volume to describe the resulting fluorescence signal. The illumination is modulated at frequencies from 1 Hz to 100 Hz...
