An electronically accessible server receives, stores, and sends value information from customers. The server or other digital medium stores the value information generated by independent users. Triggers or interactions can be used to determine when value information would be useful for a user of a client system. The value information can include customer assessments, usage frequency, navigational pointers, executable program code, instructions, product information, and service information. A digital medium is used to store value information generated by independent users. The medium can be coupled to an electronic communication network to allow for interchange of information.

A new recommendation technique, referred to as "personality diagnosis", can be seen as a hybrid between memory-based and model-based collaborative filtering techniques. Using personality diagnosis, all data can be maintained throughout the processes, new data can be added incrementally, and predictions have meaningful probabilistic semantics. Each entity's reported attributes can be interpreted as a manifestation of their underlying personality type. Personality type can be encoded simply as a vector of the entity's "true" values for attributes in the database. Given an active entity's known attribute values, the probability that they have the same personality type as every other entity can be determined. Then, the probability that they will have a given value for a valueless attribute can then be determined based on the entity's personality type. The probabilistic determinations can be used to determine expected value of information.

The present invention discloses a method for performing a stochastic analysis of one or more hydrocarbon reservoir exploitation strategies taking into consideration one or more uncertain parameters. The method optimizes an objective function that considers the gain in value of a reservoir management goal attributable to these exploitation strategies. The methodology may be used to decide whether or not to implement a strategy. Alternatively, it may be used to decide which competing strategy will yield the maximum benefit. In another embodiment of the present invention, the value of information obtained from the installation of additional sensors or new measurements is also considered.

Methods, devices and systems for moderating and policing voluntarily established transparency regarding past and present, and personal and professional relationships via online networking services. Identity of a person or commercial entity is verified before registration as a user. Each user is permitted a single profile. A profile includes a record of all relationships entered in the profile, some of which may be hidden by user. Each user is capable of linking his profile to profiles of other consenting users. Owner of a profile may flag inaccurate information on other linked profiles. The reliability or value of information in a profile is measured as a function of duration of existence of profile, transparency of the information in the profile, periods of inactivation, and number of times the profile is correctly flagged. A code is generated and used to allow gradual exposing of the profile of a user to his prospective contacts.

Augmenting processing of information objects transferred among processors within a network. Processing is performed by a process, or processor, (called a "robot") at any point in the network where an information object is transferred, or where the object resides. By allowing processing at source, destination and at "interim" points between the source and destination, the ability to add functionality, services, control and management of objects and object transfers is greatly enhanced. The robots, can reside at any point in the system. A robot can be local to an end-user's computer, can reside on a content source server, or can be on another computer, processor, storage location or device on the network. Any type of processing can be performed by the robots. For example, access rights can be maintained so that certain attributes and values of information objects are restricted on a per user, per machine, chronological or other basis. Robots can use conditions which, when satisfied by attribute/value pairs within a specific object, or conditions which are satisfied by other, external, conditions, trigger specific processing. The processing can include one or more objects, other information processing, software or hardware control functions, etc. Information can be appended to objects. Statistics on object use, publication, subscription or transfers can be compiled. Groups of robots can operate in cooperation. Robots can share information.

The present invention leverages analysis methods, such as expected value of information techniques, rate-based techniques, and random selection technique, to provide a fusion of low-level streams of input data (e.g., raw data) from multiple sources to facilitate in inferring human-centric notions of context while reducing computational resource burdens. In one instance of the present invention, the method utilizes real-time computations of expected value of information in a greedy, one-step look ahead approach to compute a next best set of observations to make at each step, producing “EVI based-perception.” By utilizing dynamically determined input data, the present invention provides utility-directed information gathering to enable a significant reduction in system resources. Thus, of the possible input combinations, the EVI-based system can automatically determine which sources are required for real-time computation relating to a particular context.

User interfaces for relaying notifications to users are disclosed. In a pulsing mode, information is faded into a predetermined area of a display, where the information has a net value greater than a predetermined or dynamically computed threshold. In a stream-cycling mode, for a number of different information sources, a display time is determined for each notification based on the information's importance. Each information is displayed in turn for a length of time equal to the display time, within the predetermined area of the display. In a stream-stacking mode, information from each of a number of sources is displayed in a corresponding source summary window. When the net value of information in a notification is greater than a predetermined or computed threshold, the information may be streamed in a main notification window and can be journaled in a journal window.

A supercritical refrigeration cycle comprises a radiator 2 for cooling the refrigerant discharged from a compressor 1, a cooling fan 2a for blowing the atmospheric air to the radiator 2, a decompression unit 4 for decompressing the refrigerant at the outlet of the radiator 2 and having the opening degree thereof controlled to achieve a target high pressure, and an evaporator 5 for evaporating the low-pressure refrigerant decompressed by the decompression unit 4. The high pressure exceeds the critical pressure of the refrigerant. A value of information representing the difference between the actual radiation state of the refrigerant at the outlet of the radiator 2 and the ideal radiation state determined by the atmospheric temperature is calculated, and based on this value of information, the air capacity of the cooling fan 2a is controlled to decrease the difference. Thus, the cooling fan of the high-pressure radiator can be properly controlled in the supercritical refrigeration cycle.

A diagnostic system and method for enabling multistage decision optimization in aircraft preflight dispatch. The diagnostic system includes an interface for receiving one or more inputs relating to one or more observed symptoms indicative of a failed component in an aircraft. The diagnostic system extends an entropy-based value of information (VOI) diagnostic model by adding an explicit value function into the VOI diagnostic model to accommodate various variables associated with the aircraft preflight dispatch problem. The construction of the entropy-based VOI diagnostic model and thus the extended VOI diagnostic model are both based upon at least one of systemic information relating to aircraft components and input-output relationships of the aircraft components, experience-based information relating to direct relationships between aircraft component failures and observed symptoms, and factual information relating to aircraft component reliability.

The invention provides a method and a device for correcting an energy value. The method comprises the following steps: presetting an energy correction coefficient table; calculating the product of the to-be-corrected energy value of each to-be-corrected single event and the energy correction coefficient of the each to-be-corrected single event to obtain the corrected energy value of the each to-be-corrected single event; counting an energy value-count value curve according to the corrected energy value. The energy correction coefficient is the ratio of a theoretical energy peak value in the energy valve-count value curve obtained by counting an extensive source radiation scintillation crystal array to a detected energy peak, thus the obtained corrected energy value of each to-be-corrected single event deviates towards the theoretical energy value of information about the position of the to-be-corrected single event, thereby eliminating the deviation between an energy value corresponding to a detected count peak value and an energy value corresponding to the theoretical count peak value on the premise of not reducing the statistical information of a scintillation crystal array edge single event.
