This work investigates three aspects: (a) a network vulnerability as the non-uniform vulnerable-host distribution, (b) threats, i.e., intelligent malwares that exploit such a vulnerability, and (c) defense, i.e., challenges for fighting the threats. We first study five large data sets and observe consistent clustered vulnerable-host distributions. We then present a new metric, referred to as th...

Uniformity distribution of the corner rounding radius of curvature is investigated using reflectanceand transmittancebased optical scatterometry. Arrays of square contact holes are measured at multiple locations on an ACI photomask using a broadband spectrophotometer capable of collecting polarized reflectance (Rs and Rp) and polarized transmittance (Ts and Tp) spectra in 190 – 1000 nm waveleng...

It is not clear how various wetting agent products affect moisture distribution throughout sand-based putting green rootzones. The objective of this research was to determine how localized dry spot (LDS) incidence, and soil moisture values and uniformity were affected by the application of five commercially available wetting agents. Wetting agents were applied during the 2008 growing season and...

Thermoforming is a well-known manufacturing process in the productions of various plastic household and industrial solutions. The heating of a plastic sheet allows the plastic to soften and within its forming window temperature the sheet can replicate a required shape when pressed against a mould. Hence, the heating process is an important thermoforming stage that determine uniformity of the ma...

We examine the propagation of collisionless particles emitted from a spherical shell to infinity. The number distribution at infinity, calculated as a function of the polar angle, exhibits a small deviation from uniformity. The number of particles moving from the polar region toward the equatorial plane is slightly larger than that of particles in the opposite direction, for an emission radius ...

the scarcity of irrigation water and decrease of water resources are the most important limiting factors in crop production in countries such as iran. thus, studying the optimum use of water and increasing water use efficiency are essential to the agricultural sector. the use of a low pressure hydroflume has been suggested to replace traditional surface irrigation methods. the aim of this resea...

this research investigates the effect of the post-cure time on the residual stresses in laminated composites. laminated composites were made of t300 carbon fibers and epoxy resin. the post-cure process was carried out at the constant temperature of 120 °c for 6 and 12 hours for two specimens. the slitting method was employed to determine through-thickness residual stress distribution of the com...

this study explores the person/number suffixes in laki in a descriptive-analytic method. having a broad distribution, these suffixes can attach to subject and object nps, prepositions, and verbs. by considering the uniform syntactic behavior of subjects of transitive and intransitive predicates and it’s contrast with the behavior of objects of transitive predicates, the authors show that these ...
