The importance of adhesive bonds in the field joining technology is increasing due to their advantageous properties. One these attributes possibility reduce weight compared welded joints group components. For a safe design, knowledge lifetime components essential. Various methods are used for prediction under cyclic loading. On one hand there test-based methods, on other simulation-based approa...

The Wireless Sensor Networks (WSN) particularly for real time applications raise fundamental problems for the scientific community. These problems are related to the limit of energy resource and the real time constraints on the communication delay. The well functioning of such networks depends mainly on the network lifetime result of nodes energies and the communication delay which should meet ...

Over the last few years a theoretical treatment for the weak decays of heavy-flavour hadrons has been developed that is genuinely based on QCD. Its methodology is described as it applies to total lifetimes, and the underlying theoretical issues are discussed. Theoretical expectations are compared with present data. One discrepancy emerges: the beauty baryon lifetime appears to be significantly ...
