Abstract The structural stability failure is a critical factor for arch bridges which are not transversally braced and that must be considered when the bearing capacity has to determined. One of main parameters dictating behaviour arched structures in case loss their slenderness. Accordingly, with high stiffness low flexibility expected have significantly increased capacity. current paper consi...

There are many different approaches to elicit requirements each having its strengths and weaknesses. Hence, some approaches may be ore suitable to one domain then another. Moreover, some domains may require these approaches to be carefully applied or even adapted to work efficiently. Health care domain is one of these domains. It is a complex domain with many subtleties, such as political and l...

Biometric authentication systems are presented as the best way to reach high security levels in controlling access to IT systems or sensitive infrastructures. But several issues are often not taken properly into account. In order for the implementation of those systems to be successful, the hidden risks and the related liabilities have to be carefully analyzed before biometrics can be used on a...

Bilinear R-parity violation is a simple extension of the MSSM allowing for Majorana neutrino masses. One of the three neutrinos picks up mass by mixing with the neutralinos of the MSSM, while the other two neutrinos gain mass from 1-loop corrections. Once 1-loop corrections are carefully taken into account the model is able to explain solar and atmospheric neutrino data for specific though simp...

Endometrioma surgery should be planned and executed very carefully as it is associated with risks that may hamper future reproductive potential. Symptoms, age, risk of malignancy, bilaterality, ovarian reserve, and desire to have children should all be taken into account prior to surgical intervention. Cyclic and noncyclic severe pain may be an indicator or deep infiltrating diseases. Laparosco...

In order to take account of the spatial fluctuation beyond the dynamical mean field theory (DMFT), the two-particle self-consistent theory is carefully reinvestigated and is proved to be unable to reproduce the correct low energy scale in the strong correlation limit. An improved theory is proposed which starts from DMFT and is combined with the spin-fluctuation theory (SFT) in a phenomenologic...
