The aim of our research on AP1000 is to measure the overhead of some barrier algorithms and analyze how to take advantage of the AP100 architectural properties in order to obtain the best performance. We have measured the performance of various barrier algorithms on the AP1000. Our results were obtained by embedding barrier episodes inside a loop and averaging over a large number of operations....

The peculiar nature of electron scattering in graphene is among many exciting theoretical predictions for the physical properties of this material. To investigate electron scattering properties in a graphene plane, we have created a gate-tunable potential barrier within a single-layer graphene sheet. We report measurements of electrical transport across this structure as the tunable barrier pot...

The diffusion barrier properties of HfNx and Hf–Ge–N thin films for Cu metallization on Ge are examined. The diffusion barrier films were deposited by reactive sputtering on p-Ge 001 single crystal substrates with varying thicknesses. Cu thin films were then deposited in situ on the diffusion barrier. The multilayer film structure was subsequently annealed in an Ar atmosphere. X-ray diffraction...

Even though various multi-layered tablets have been developed for sustained release formulations, evaluations of mechanical properties during dissolution with drug release and imaging in the tablets have been limited. A novel geometric system consisting of an inner immediate release layer and two extended release barrier layers with swellable hydrophilic polymers was suggested as a once-a-day f...

We consider the volumetric barrier for semide2nite programming, or “generalized” volumetric barrier, as introduced by Nesterov and Nemirovskii. We extend several fundamental properties of the volumetric barrier for a polyhedral set to the semide2nite case. Our analysis facilitates a simpli2ed proof of self-concordance for the semide2nite volumetric barrier, as well as for the combined volumetri...

The film-forming ability of bagasse hemicellulose and its potential for packaging were investigated in terms of its mechanical and water vapor barrier properties. The films were prepared under various hemicellulose concentrations, chitosan/glycerol amounts (based on the amount of hemicellulose), and temperatures. These were subsequently evaluated by measurement of their mechanical and water vap...

Nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. Antimicrobial nanocomposite LDPE films containing ZnO nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-ZnO pulse 10% polyethylene grafted maleic anhydride (PE-g-MA), w/w pure LDPE), were p...

Six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. The thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. The impact resistance weight also varies fro...
