System and method for correlating user data from a content provider and user data from an advertising provider that is stored on autonomous systems

An autonomous correlation system correlates user data from a content provider and advertising view data from an advertising provider, wherein the user data is present on one autonomous system and the advertising view data is present on another autonomous system distinct from the one autonomous system, the systems being autonomous in that each is normally secured against unconstrained access by another. The autonomous correlation system comprises logic to accept a first message from a user, wherein the first message contains an indication of an object being presented to the user, the object being at least one of a content page and an advertisement, a first user identifier associated with the user by a presenter of the object; a reference database for storing an association between the first user identifier and the user; logic to accept a second message from the user, wherein the second message contains an indication of an object being presented to the user, the object being at least one of a content page and an advertisement, a second user identifier associated with the user by a presenter of the object; wherein the reference database stores an association between the second user identifier and the user.

Comprehensive treatment agent for soda alkaline land and use method thereof

The invention discloses a soda saline-alkali land comprehensive treatment agent and a use method thereof, and belongs to the technical field of control agents for improving moderate and severe soda salinization. The comprehensive treatment agent consists of a modifier and an organic fertilizer, wherein, components of the modifier comprise humic acid, zeolite, a acid conditioner, fly ash and furfural residue; and the components of the organic fertilizer comprise fermented chicken manure, crushed straw and wood vinegar liquid. The comprehensive treatment agent is applied at 13-17t per 1 hectare of saline-alkali land before harrowing and transplanting. The action mechanism of the soda saline alkali land comprehensive treatment agent integrate physical and chemical functions of chemical salifying, complexing, neutralizing, ion exchange, adsorption, desorption, passivation, fixing, preventing salt accumulation, emulsion breaking and like; which increase CEC by times, desorbs and leaches base and basic group in soil, significantly decrease the pH value, greatly reduce soluble Na ions; and a formed anti-salt accumulation plow pan structure really takes effect of 'salt isolation' and 'alkali decrease', thus realizing rice harvest in the same year of construction and cultivation.

Secure content based routing in mobile ad hoc networks

The present invention describes methods and systems for information dissemination in mobile ad hoc networks founded on Content Based Routing. The method comprises generating a first data packet at a source node, encoding, via an encoding logic within the source node, a plurality of information categories associated with the first data packet in a header of the first data packet, encrypting the first data packet with an encryption key unique to the plurality of information categories, generating a second data packet having a unique dissemination group identity in its header and the encrypted first data packet as a payload of the second data packet, disseminating the second data packet across a dissemination mesh, and receiving the second data packet at a destination node. The system comprises a host within the source node that generates a first data packet comprising a first packet header and the content within a first payload of the first data packet, an identity generator within the source node to receive the first data packet and to generate a dissemination group identity for a dissemination group, an encoding unit to encode within the first packet header a plurality of information categories associated with the content, an encryption unit for encrypting the first data packet with an encryption key unique to the dissemination group identity, such that a second data packet is formed, the second data packet having in a second header the dissemination group identity and in a second payload the encrypted first data packet, and a routing unit to disseminate the second data packet to the dissemination mesh.

SiO2 nanoscale porous material with aerogel property prepared by microwave reaction and preparation method thereof

The invention provides a SiO2 nanoscale porous material with aerogel property prepared by microwave reaction and a preparation method thereof; the nanoscale porous material comprises silicon dioxide skeletons (1) and bubble-shaped nanoscale pores (2), wherein the foam-shaped nanoscale pores (2) are arranged among the silicon dioxide skeletons (1). The preparation method comprises four steps, namely preparation of silicon dioxide sol, preparation of wet gel, aging of mother solution and drying at normal pressure and the preparation of silicon dioxide sol comprises the following steps: adopting organosiloxane, organic solvent, water and acid catalysis as raw materials; mixing each components in a defined ratio in a container while adopting microwave radiation to perform hydrolytic polycondensation reaction or adopting microwave radiation to perform hydrolytic polycondensation reaction after mixing the components. Owning to adopting microwave radiation technology, a lot of bubbles are generated in silicon dioxide sol, a large quantity of nanoscale bubble-shaped pores are formed on the silicon dioxide substrate, and meanwhile silicon dioxide space skeletons are retained so that silicon dioxide porous material with extremely large specific area and higher intensity can be obtained. In addition, because carbon dioxide supercritical drying process is not needed, the production cost is greatly reduced.
