摘要:
Techniques are described for controlling the climate in a data center. Using the input of an administrator, multiple desired attributes of a data center (e.g., temperature, energy consumption, costs, or system performance) may be balanced using a utility function that maximizes the utility of the computing systems in the data center according to the administrator's preferences. Additionally, a cooling model is generated that represents the affect of a control parameter (e.g., the fan speed of a CRAC) on the desire attributes of the data center. The cooling model may then be substituted into the utility function to replace the desired attributes. Using this new utility function, the control parameters may be varied such that the maximum utility is achieved.

Methods and apparatus are provided for the dynamic placement, management and monitoring of Internet advertising. A provider of Internet content distributes the Internet content by embedding an advertisement placeholder in the Internet content; and provides the Internet content to an aggregator web site. The aggregator web site presents the Internet content to at least one end user with at least one advertisement in the advertisement placeholder. The advertisement placeholder is processed by a third party agent to automatically share revenue from the at least one advertisement with the provider of the Internet content and a provider of the aggregator web site. The advertisement placeholder can optionally be embedded in the Internet content using one or more templates. The third party agent also evaluates the content and at least one policy of multiple parties to identify at least one advertisement to present in the advertisement placeholder. The advertisement placeholder embodies a three party agreement between the provider of the Internet content, the provider of the aggregator web site and at least one advertiser.
摘要:
Documents returned by a search engine may be good keyword matches to the search query terms, but may not historically have been very effective in addressing user needs. Documents which have historically been effective in addressing user needs are said to have high efficacy. Disclosed are methods that try to assess the beginning and ending of user search sessions, assume that documents that are the last document looked at are those with the highest efficacy, and incorporate this notion of efficacy in returning-search results.

The invention enables server administrators (SAs) to improve their productivity and performance. With the methods and systems described herein, the prior art needed to search for appropriate tools for appropriate tasks is minimized and/or eliminated. Easier scripting and automation that does not require implementation across tools is provided. A consistent logical place is provided for all resources to be used. Standardization of tools enables improvements in service quality. Tools may be provided using one unambiguous authoritative data model, which eliminates data inconsistencies between sources. With the invention, updates to service delivery clients may be delivered more quickly. The invention also reduces costs for developing, deploying, and maintaining a tightly integrated service delivery client. Integration may be provided from the bottom up rather than after the fact. With the invention, common base objects are provided for events, problem and change records, and other system administration artifacts

A method and apparatus are disclosed for facilitating coinless transactions by rounding a fractional transaction cost up or down to a whole-unit amount. A fractional transaction cost is rounded up or down to a whole-unit amount based on a generated random number that ensures fairness to both buyers and sellers, over time. If a transaction purchase price is N.C units, where N is any non-negative integer and C is an integer between 0 and 99 indicating the fractional cost between 0 and 0.99, then a buyer will be charged N+1 units with a probability of p equal to C/100 and N units with a probability of 1−p. The random number generation process can ensure that the rounding process does not favor buyers or sellers, for example, by (i) incorporating a buyer-provided offset, or (ii) having the generation of the random number performed or supervised by a trusted third party. The buyer can increase his or her odds of having the final purchase price rounded down by exposing more than just the amount by which the rounded up cost exceeds the fractional cost.
摘要:
Techniques are provided for discovery and monitoring of an environment using a plurality of robots. A plurality of robots navigate an environment by determining a navigation buffer for each of the robots; and allowing each of the robots to navigate within the environment while maintaining a substantially minimum distance from other robots, wherein the substantially minimum distance corresponds to the navigation buffer, and wherein a size of each of the navigation buffers is reduced over time based on a percentage of the environment that remains to be navigated. The robots can also navigate an environment by obtaining a discretization of the environment to a plurality of discrete regions; and determining a next unvisited discrete region for one of the plurality of robots to explore in the exemplary environment using a breadth-first search. The plurality of discrete regions can be, for example, a plurality of real or virtual tiles.

Methods and apparatus are provided for automatically detecting spelling errors in one or more documents, such as documents being processed for the creation of a lexicon According to one aspect of the invention, a spelling error is detected in one or more documents by determining if at least one given word in the one or more documents satisfies a predefined misspelling criteria, wherein the predefined misspelling criteria comprises the at least one given word having a frequency below a predefined low threshold and the at least one given word being within a predefined edit distance of one or more other words in the one or more documents having a frequency above a predefined high threshold; and identifying a given word as a potentially misspelled word if the given word satisfies the predefined misspelling criteria.

Mechanisms are provided for determining the location of computing assets within an organization. These mechanisms determine first location information identifying a location of at least one first physical asset housing in a predetermined physical area of the organization relative to a predetermined coordinate system, and second location information identifying a location of at least one second physical asset housing within the at least one first asset housing. The mechanisms automatically determine third location information identifying a location of at least one computing asset within the at least one second physical asset housing. In addition, the mechanisms generate an asset location map data structure for the organization based on the first, second and third location information. The mechanisms also perform at least one management operation for managing resources of the organization, based on the asset location map data structure for the organization.

Methods and apparatus are provided for automated object classification using temperature profiles. An object in an environment (such as an exemplary data center) is classified by obtaining a surface temperature profile of the object; and classifying the object as a particular type of equipment based on the obtained surface temperature profile. The surface temperature profile of the object can be compared to a plurality of predefined characteristic surface temperature profiles each associated with a given type of equipment.
