The periodical transient impulses caused by localized faults are sensitive and important characteristic information for rotating machinery fault diagnosis. However, it is very difficult to accurately extract transient impulses at the incipient fault stage because the fault impulse features are rather weak and always corrupted by heavy background noise. In this paper, a new transient impulse ext...

This paper puts together a collection of a number of previously proposed signal processing techniques to detect and diagnose faults in rolling element bearings. The collection of previously proposed signal processing algorithms contains two main phases. Phase one includes a surveillance and diagnosis stage using time, frequency and an envelope analysis over the full frequency bandwidth. The sec...

fast enzyme linked immunosorbent assay (fast-elisa) was compared with the standard elisa for the diagnosis of human hydatidosis. seventy serum samples including 30 from hydatidosis patients (surgically confirmed), healthy control individuals not infected with any parasitic diseases (n=/20) and from others with different parasitic infections including, toxocariosis (n=5), fasciolosis (n=5), tric...

introduction electron linear accelerator (linac) can be used for neutron production in boron neutron capture therapy (bnct). bnct is an external radiotherapeutic method for the treatment of some cancers. in this study, varian 2300 c/d linac was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for bnct. materials and methods photoneutron sources w...
