say, the center frequency of the spectrum of the signals, and transform the subspace at each frequency bin into the subspace created by the span of the location vectors at the focusing frequency. Then, they use a high-resolmion algorithm such as MUSIC [SI to estimate the DOA's of the sources. They show that focusing reduces the resolution threshold signal-to-noise ratio (SMZ), which is defined ...

Maximizing shareholders’ value has always been an indispensable goal for publicly traded companies. Shareholders value is highly dependent on the operating expenses, profit margin, return on investment and the overall performance in public companies. We propose a hybrid fuzzy multi-criteria decision making method for measuring the performance of publicly held companies in the Pharmaceutical ind...

The objective of this project is to explore the characteristics of inertial systems by using the MTx Motion Tracker technology for indoor geolocation. MTx is an inertial sensing technology that can be used to provide position data without the use of external reference sources. Xsens Technologies from Netherlands has developed this device to record parameters relating to dynamic movements. This ...

It is well known that damaged structural members may alter the behavior of the structures considerably. Careful observation of these changes has often been viewed as a means to identify and assess the location and severity of damages in structures. Among the responses of a structure, natural frequencies are both relatively easy to obtain and independent from external excitation, and therefore, ...
