Fixed content storage within a partitioned content platform, with disposition service
A content platform (or “cluster”) that comprises a redundant array of independent nodes is logically partitioned. Using a web-based interface, an administrator defines one or more “tenants” within the cluster, wherein a tenant has a set of attributes: namespaces, administrative accounts, data access accounts, and a permission mask. A namespace is a logical partition of the cluster that serves as a collection of objects typically associated with at least one defined application. Each namespace has a private file system with respect to other namespaces. This approach enables a user to segregate cluster data into logical partitions. Using the administrative interface, a namespace associated with a given tenant is selectively configured without affecting a configuration of at least one other namespace in the set of namespaces. One configuration option is a “disposition service” that, once enabled for a namespace, automatically deletes objects that were once under retention and whose retention time has expired. Preferably, the disposition service deletes objects that do not have a “retention hold” associated therewith. The service enables the content platform to automatically reclaim cluster capacity while minimizing external involvement and archive load.

Returns-timing for multiple market factor risk models
Until recently, risk models have been built using low frequency data, such as weekly or monthly data. This approach has resulted in a necessary compromise between model stability for which one needs a long history of data, and model responsiveness, for which, the shorter the history, the better. Stability plus responsiveness can be achieved if one uses daily data, which allows for a large number of observations to be used in model estimation without using long out-of-date data. Daily data have other problems, however, as the differing closing times of markets worldwide may induce spurious relationships across model factors. In particular, correlations between markets may appear lower than they truly are due to a market lag effect. To address such issues, a stable, daily data-based factor risk model is described which takes account of the differing market closing times and corrects the model factor correlations and specific returns accordingly.

Pulse oximeter probe-off detector
A processor provides signal quality based limits to a signal strength operating region of a pulse oximeter. These limits are superimposed on the typical gain dependent signal strength limits. If a sensor signal appears physiologically generated, the pulse oximeter is allowed to operate with minimal signal strength, maximizing low perfusion performance.

The first type of data codes are coded as the codewords and indicating data to be disclosed. An end identification code is added to an end of a code string composed of the first type of data codes, the end identification code showing the end. Second type of data codes are mapped after the end identification code in the code area, the second type of data codes being coded as the codewords and indicating data to be kept in secret. Filler codes showing no data after the second type of data codes are mapped to fill up the code area, when a total amount of the codewords in the code area is less than a capacity of the code area.
Encryption key distribution method in mobile broadcasting system, and system for the same
An encryption key distribution method for service and content protection in a mobile broadcasting system, and a system for the same which includes generating, by a network, a first encryption key when the broadcast service is first provided; transmitting a generalized rights object message, which includes identification information for identifying the generated first encryption key, to the terminal; generating a second encryption key before the lifetime of the first encryption key expires; and transmitting the generalized rights object message, which includes identification information for identifying the generated second encryption key, to the terminal.
Techniques for transmitting control channel information
Techniques for protecting information elements transmitted to mobile stations from intruders. The technique can involve applying a randomized mask over an information element and then providing a scrambled cyclic redundancy check (CRC) value. A seed for the randomized mask can be different from a seed for the scrambled CRC value.

Integrating embedded links with call center operation
In various embodiments, advertising campaigns can be defined that incorporate technologies such as two-dimensional bar codes or embedded links in electronic material, for directing a user to communicate with a call center. For instance, in particular embodiments, the reading of a two-dimensional bar code may cause a communication to be sent to, and received at, the call center, where a calling campaign associated with an advertising campaign is identified using information associated with the communication. Likewise, in particular embodiments, the activation of an embedded link may cause a communication to be sent to a publisher, who sends a communication to the call center. Upon determining the calling campaign, an appropriate agent is selected and a communication, such as a voice call, is initiated to the user. In particular instances, if a no-answer condition is reached as a result of the communication, another communication may be scheduled for a later time.
Cloud-based virtual tandem
Peering partners register with a peering grid for direct broadband routing of call offers. The peering grid terminates call offers on behalf of peering partners, collecting call detail records, summarizing termination usage, and calculating a payment to be provided to the peering partner in return for using the services of the peering grid. A call detail record may be generated for the peering partner, which may include a market value of call traffic, a variable cost of the call traffic, and a determined compensation amount. The market value is based on revenue for terminations of the call traffic from the peering grid, the variable cost is a function of sharing the market value between the peering grid and the peering partner, and the compensation amount due is a function of the variable cost.
Cybercrime detecting and preventing method and system established by telephone number code, authorization codes and source identification code
A cybercrime detecting and preventing method and system includes a website, an interface dynamic web page, a search program, and a database. When a network user inputs a “telephone number code” and “authorization code” of a network server using an internet accessing device, the user is also required to input a “source identification code.” When access to a network receiver or server is requested, a “telephone number code and authorization code” set is input to the website for comparison with “telephone number codes” and “authorization codes” stored in the database. If the input “telephone number code and authorization code” set does not match the stored “telephone number code and authorization code” set, the “source identification code” is transmitted to a computer to be analyzed and determine the location of the cybercriminal and relay information on the cybercrime to an appropriate public security organization.
