Most modern Web browsers export a rich API allowing third-party extensions to access privileged browser objects that can also be misused by attacks directed against vulnerable ones. Web browser vendors have therefore recently developed new extension frameworks aimed at better isolating extensions while still allowing access to privileged browser state. For instance Google Chrome extension archi...

Scatterometry is presented as an optical metrology technique potentially capable of determining the critical parameters of phase shifting diffraction grating test structures (sidewall profile, linewidth, and etch depth where appropriate). The technique is noncontact, rapid and nondestructive. The test grating structure is illuminated by a laser beam and the intensities in the different diffract...

Traditional user-based permission systems assign the user’s full privileges to all applications. Modern platforms are transitioning to a new model, in which each application has a different set of permissions based on its requirements. Application permissions offer several advantages over traditional user-based permissions, but these benefits rely on the assumption that applications generally r...

A step towards minimizing the environmental pollution of leather tanning , chrome shavings wastes were treated with Li2CO3 to extract technical or industrial gelatin as an added value material. Isolation and characterization obtained from chrome-tanned done. The alkali hydrolysis products obtained, showed good physical chemical properties in terms gel strength, swelling thermal stability. optim...

The existing NIDSs involve various mechanisms in order to identify the patterns related to the network problems. In this paper we described the implementation of genetic algorithm using steady-state selection mechanism. We have performed various test cases in order to analyze the effect of varying iterations and varying initial chrome length along with different fitness functions. The analyzed ...

Persons working in nickel refineries, arsenic smelters and chrome plating factories are exposed to chromium compounds. Hexavalent chromium has been implicated for its toxic effects on the nasal mucosa. Detailed data of 108 workers, dealing in manufacturing of Chrome and its compounds, was collected concerning age, occupational history and clinical examination. Of the 108 cases, 52 cases had nas...
