Biometrology in Tissue Engineering: Thoughts and Concepts

The range of measurement techniques have increased in number and quality in recent decades. Qualitative methods have been increasingly applied to research in biological and health fields.

However, Biotechnology and more specifically Tissue Engineering have reached a point that requires a step further.

This step will be the adoption of Metrology (metrological standardization and metrological traceability) as a fundamental practice in scientific research and development of new therapeutic approaches.

Radiation Measurements without Posing the Inversion Problem

Radiation measurement is an exponential analysis, which is an “illposed” problem, where the solution is not unique. Therefore, the accuracy of data points is critical.

If the radiation detector is sensitive during the dead time, usually an extended dead time signal processing method is necessary and the calculation of the dead time and pile up rate invoke the inversion problem, which is difficult to solve, and only approximated.

We have used two new approaches, where the inversion problem is not posed, and there is no need to assume the Poisson distribution or constant source strength.

Measurement and Characterization of Flexible Absorbing Materials for Applications in Wireless Communication

Absorbing materials are widely applied in applications of wireless communication. It is of great importance to measure and characterize these materials efficiently and precisely.

In this paper, the author first utilizes transmission line methods to acquire scattering parameters, which are used as input in the parameter retrieval process for EM properties.

After successful characterization of these materials, EM properties are imported in commercialized software for simulation of reflectivity. For comparison, NRL arch reflectivity test is conducted and good comparison is found. Discrepancy between the two is analyzed in this paper.
