Advantageous methods for synthesis of fluorinated phthalocyanines are provided. Typical implementation involves a reaction mixture that includes perfluoro compound that is reacted for a reaction period sufficient to yield a fluorinated phthalocyanine of formula F64PcM, wherein “Pc” is any phthalocyanine macrocycle and “M” is hydrogen. Novel fluorinated phthalocyanine molecules/compounds are also provided herein, including specifically compounds that include fluorinated phthalocyanines wherein “M” is Cu or V═O. The fluorinated phthalocyanines have wide ranging applications, e.g., corrosion-related applications, coating-related applications, catalysis, and the production of optical and electronic materials.
摘要:
A method of hiding data comprising creating a histogram of an attribute of a first data set. The histogram includes occurrences of the attribute. Two adjacent occurrences are selected where a count of one of the two adjacent occurrences is zero. A second data set is embedded in data of the first data set associated with the selected adjacent occurrences.

A generalized multi-parameter mapping function aggregates decision criteria into a single virtual criterion to rank the potential relay candidates. Optimal rules for next hop relay as applicable to both transmitter-side selection and receiver-side election based forwarding schemes are also provided. Examples of network performance based on two optimization criteria include one-hop progress (greediness) and packet success rate (link quality). A suitable mapping function trades off the greediness for link quality. Simulation information is provided that indicates that the implementation according to the mapping function outperforms the reported transmitter-side link-aware forwarding schemes.

Embodiments are directed toward a method for Behavior-based Traffic Differentiation (BTD) that initially receives incoming packets and performs traffic classification to determine the protocol of the incoming packets. In addition, BTD performs bandwidth division/allocation to further support traffic classification amongst non-TCP traffic types such as UDP and ICMP. For TCP traffic, the method for BTD determines whether a TCP connection has been established and performs at least one of rate limiting, waiting time reduction for half-open connections, and incrementing backlog queue size, when the TCP connection has not been established. If the TCP connection has been established successfully, the method for BTD further includes proactive tests for traffic differentiation which identify normal traffic, which is admitted, and attack traffic, which is dropped.
摘要:
A dynamic upstream bandwidth allocation scheme is disclosed, i.e., limited sharing with traffic prediction (LSTP), to improve the bandwidth efficiency of upstream transmission over PONS. LSTP adopts the PON MAC control messages, and dynamically allocates bandwidth according to the on-line traffic load. The ONU bandwidth requirement includes the already buffered data and a prediction of the incoming data, thus reducing the frame delay and alleviating the data loss. ONUs are served by the OLT in a fixed order in LSTP to facilitate the traffic prediction. Each optical network unit (ONU) classifies its local traffic into three classes with descending priorities: expedited forwarding (EF), assured forwarding (AF), and best effort (BE). Data with higher priority replace data with lower priority when the buffer is full.

A system and method are disclosed which may include subjecting an original, pixel domain image to an Integer Wavelet Transform (IWT) to obtain a matrix of IWT coefficients; selecting a plurality of the IWT coefficients for incorporation of information therein; and setting signs for the plurality of selected IWT coefficients according to bit values of a plurality of respective data bits. The system and method can also include subjecting a marked pixel domain image to an Integer Wavelet Transform to obtain a matrix of wavelet coefficients; selecting a plurality of the coefficients from the matrix that contain embedded information; and for each selected coefficient, extracting the data bit embedded in the coefficient, a bit value of the extracted data bit determined based on a sign of the coefficient.
摘要:
Techniques for the delivery of metered amounts of liquid material include the use of a pin (3), such as an optical fiber. A sample of the liquid material may be placed on the tip (7A) of the pin for delivery to a target area, such as a specific location on a microarray, in a contactless manner. Light transmitted through the pin may be detected to facilitate accurate measuring of the pin's position.
