The role of type II FB (I):Tl+ color center at low coordination surface sites of AgBr thin films in providing tunable laser activity and photographic sensitization is examined. The double-well potential at this site is ...

This paper introduces a framework for security-oriented software service composition and evolution. Key building blocks of the framework are a semantic model for specifying the security objectives and properties at the ...

Observations of vacancy clusters formed in Czochralski (Cz) Si after high energy ion implantation are reported. Vacancy clusters were created by 2 MeV Si ion implantation of 1 × 10 15 ions/cm 2 and after annealing between ...

The corrosion properties of duplex-treated and nitrided Ti-6Al-4V have been investigated in 0.025, 0.25 and 2.5 M NaCl using electrochemical techniques, Positron Annihilation Spectroscopy (PAS), X-ray diffraction (XRD), ...

This study has investigated the effect of shelf aging, for up to one year in air, on the properties of gamma-irradiated ultra-high molecular weight polyethylene (UHMWPE). A variety of techniques were used to characterize ...

The influence of 70 keV He + ion implantation and subsequent annealing of Cz-indium phosphide (InP) samples has been investigated using a slow positron beam-based Doppler broadening spectrometer. Three samples with ion ...

Two potentiometric sensors responsive to sildenafil citrate (SC) drug (the active component of viagra) are described, characterized, compared and used for drug assessment. The sensors are based on the use of the ion-association ...

This paper presents a unique storage architecture that utilizes the multiplicity of storage nodes in LAN and WAN network environments to achieve high reliability, high-performance, scalability, and cost effectiveness. The ...

Nonlinearity of the extraction process is addressed via the application of instantaneous linearization to control the extract and raffinate concentrations. Two feed-forward neural networks with delayed inputs and outputs ...
