摘要:
A multilayer compensator includes one or more polymeric first layers and one or more polymeric second layers. The first layers comprise a polymer having an out-of-plane (Δnth) birefringence not more negative than −0.01 or not more positive than +0.01. The second layers comprise an amorphous polymer having an out-of-plane birefringence more negative than −0.01 or more positive than +0.01. An overall in-plane retardation (Rin) of the multilayer compensator is greater than 20 nm and the out-of-plane retardation (Rth) of the multilayer compensator is more negative than −20 nm or more positive than +20 nm. The in-plane retardation (Rin) of the one or more first layers is 30% or less of the overall in-plane retardation (Rin) of the multilayer compensator.

摘要:
A system for detecting a remotely controlled e-mail spam host. The system includes an E-mail spammer detection unit and a host traffic profiling unit. The E-mail spammer detection unit identifies E-mail Spammers based on SMTP traffic characteristics. The host profiling unit extracts traffic components from the plurality of Internet traffic associated with an E-mail Spammer; interprets the extracted traffic components and determines whether the E-mail Spammer is a compromised host. The system may also include a botnet controller detection unit that analyzes traffic associated with compromised E-mail Spammers and identifies the botnet Controller remotely controlling the compromised E-mail Spammer.
摘要:
A method and apparatus for generating a reconnaissance index for a communications network is described. In one embodiment, scan detection data is initially received. A number of scan flows and a number of unique source Internet protocol (SIP) addresses initiating said number of scan flows is then identified from said scan detection data. Afterwards, a reconnaissance index is generated by utilizing said number of scan flows and said number of unique SIP addresses.

摘要:
A nanocomposite optical plastic article has a plastic host material with a temperature sensitive optical vector (x) and a core shell nanoparticulate material dispersed into the plastic host material. The core shell nanoparticulate material is characterized by a core defined by a nanoparticulate material which has a temperature sensitive optical vector (x1) and a shell defined by a coating material layer coated onto the core. It is important to the invention that temperature sensitive vector (x1) is directionally opposed to the temperature sensitive optical vector (x) and nshell
