Abstract: A method and system is provided for calculating importance of documents b ased on transition probabilities from a source document to a target document based on looking ahead to information content of target documents of the so urce document. A look-ahead importance system generates transition probabili ties of transitioning between any pair of source and target documents based on analysis of links to target documents of the source document. The system may calculate the transition probabilities based on the number of links on d ocuments a look-ahead distance away. The system then solves for the stationa ry probabilities of the transition probabilities. The stationary probabiliti es represent the importance of the documents.

Abstract: We describe a model for multilevel information security. Information security is defined as combinations of confidentiality, integrity and availability. These three aspects are regarded as properties of a generic information object, and are treated as mutually independent. Each aspect is represented by an axis in an n-dimensional vector space, where n is the number of independent security aspects of interest. The model can ensure directed information flow along an arbitrary number of axes simultaneously. An information object is assigned a security label denoting the security level along an arbitrary number of axes. The model is role based. A role is assigned an access label along the same axes. Verification of a role's access to information is performed by comparing access label with security label. Since the aspects represented by each axis are mutually independent, each axis may be treated by itself. This enables a very efficient algorithm for verification of access. The model will therefore be suited for systems having low processing capacity. Based on this model, we describe a method and an apparatus to ensure confidentiality, integrity and availability for information from peripheral equipment in communications networks. Such peripheral equipment may be, but is not limited to personal terminals for rescue personnel, soldiers etc, sensors (detectors) for smoke, gases, motion, intrusion etc. The invention supports decision support systems in that the information has known confidentiality, integrity and availability even from inexpensive sensors, which do not include a processor or the like. The invention differs from prior art in that it, among other features: - Treats an arbitrary number of mutually independent aspects of information security, - Assumes that confidentiality, integrity and availability are mutually independent variables, - On this basis can verify access to information by means of simple binary operations, by a simple logic gate circuit or by a processor.

Title: Universal distributing tower
Inventor: FUKS VLADIMIR
IPC: B65G3/04
Filed: 2009-11-05
Abstract: Storage of a bulk material by build-up longitudinal piles is the most common methods of the mining industry. Building of the longitudinal piles requires long conveyors for stacking and reclaiming. Direction of the conveyors depends on the type of the piled material. Coal as hazardous materials must be stored on such manner that recirculation will be available for any point of pile and at any time. This can be reached by directing of the reclaiming conveyors opposite to stacking that allows delivering the reclaimed material to the feed point (tail) of the stacking conveyor. This way making recirculation process the most economical. In order to reach recirculation feature for more than two piles the conveying system of a coal stockyard requires additional conveyors.  In this case the conveying system for recirculation process becomes expensive and complicated. Using of bucket wheel stacker-reclaimer simplifies arrangement, but in terms of the cost and versatility makes system expensive and not always economically justified. In case of using single-boom or twin-boom stackers the recirculation requires additional conveyors and transfer towers. All the above mentioned methods implemented for high volume piles require long and complicated conveying systems. This often requires adding of transfer chutes and diverters/flop gates. Design of the stockyard handling system based on the using of sophisticated multi-way diverters allows reducing of the total length of conveyors and makes system capable to provide the required functions without high capital and operational cost (see description of the following patent).

Abstract: The present invention relates to a device for feeding and controlling of secondary air from secondary air ducts into flue gas channels of horizontal coke oven chambers. The flue gas channels are located underneath the coke oven chamber floor on which coal carbonization is realized. The flue gas channels serve for combustion of partly burnt coking gases from the coke oven chamber. The partly burnt gases are burnt with secondary air, thus heating the coke cake also from below to ensure even coal carbonization. Secondary air comes from the secondary air ducts connected to atmospheric air and to the flue gas channels.  Controlling elements are mounted in the connecting channels between the flue gas channels and secondary air ducts which can precisely control the air flow into the flue gas channels. Thereby, it is possible to achieve a much more regular heating and heat distribution in coke oven chambers. The actual controlling devices in the connecting channels can be formed by turnable pipe sections, wall bricks, or metal flaps.  It is particularly advantageous to utilize a hump-like facility (tabouret) which sits in the secondary air ducts and which is comprised of a tabouret plate with a central opening that is slid under the corresponding embranchment to regulate the gas stream. The controlling mechanism can be actuated manually, electrically, or pneumatically. Thereby, the controlling device can also be automated.
