Abstract: Aspects automatically minimize marketing rates as a function of optimized response rate models. Response rates are estimated from marketing offers targeted from a first entity to topic-entity pairs at respective specified marketing rates as a function of relative differences in their consumer sentiment scores. Marketing offers are targeted to a subset of the topic-entity pairs that each have estimated response rates meeting a threshold response rate constraint. Respective costs and actual rates of response from consumers are determined for the targeted offers. Response rates are modeled to determine modeled response parameters for the topics and entities of the subset topic-entity pairs as regressions of minimized differences in value between estimated and actual response rates. Marketing rates of the subset entity-topic pairs are minimized to meet the threshold response rate constraint and a marketing cost constraint as a function of the modeled response parameters.

The device includes a frame having at least four frame members, including two generally parallel and oppositely spaced apart lengthwise members, and two generally parallel and oppositely spaced apart widthwise members. Lateral edges of the frame members form an outside periphery and an inside periphery of the frame, the inside periphery surrounding an inside opening extending through the frame. At least two rabbets are positioned generally spaced apart and opposite each other on the frame members along the inside periphery of the frame for therein receiving edges of a breaking board so as to support the board positioned across the inside opening of the frame, and a plurality of adjustable fasteners is positioned on the frame members adjacent the at least two rabbets for fastening the breaking board on the frame.

Abstract: A method and apparatus for ensuring the coherence of multiple copies of the same data at multiple geographic locations is presented. The system operating system, the system operator or some combination of both may determine the physical disks having the file or comprising the disk families containing data which requires protection. Using the MIRROR CREATE commands in a Unisys MCP operating system environment, a mirrored disk pack set is made for each relevant physical disk identified. The disk pack set is distributed amongst at least two geographic locations. For each member of each disk pack set, the STORESAFE+command associates a site identifier with the member corresponding to the member's geographic location. During application processing, disk writes for one member of a mirrored set are performed for each member of the set. The MCP operating system checks the results of each disk write to each of the members of the mirrored disk set.

Abstract: A mainframe computing system is adapted to be loaded with one of a plurality of different operating systems and different associated microcode to provide a computing system which is capable of running user programs adapted to be executed by the loaded operated system comprises a main memory for receiving the desired operating system coupled to a system bus.

Abstract: The present invention provides a novel programmable data communications controller employed to accept data from a host computing system and for transmitting the data to a terminal designated by the host computer system. The data computer communications controller is further provided with protocols, parameters and poll tables stored in a dedicated memory of the data communications controller which enables the controller to receive data and address information from a main memory of a host computer and to reformat and pre-package the information in a protocol format block acceptable by a terminal coupled to the data communications controller. Different protocols, parameters and polls are provided in the data communications controller in the form of preprogrammed information which enables different terminals employing different protocols and protocol formats to be coupled directly to a data link interface bus without hardware modifications.

Abstract: In a high speed data processing system, there is provided a circuit for shifting either right or left as data is transmitted to or from the main storage unit. Apparatus for high speed parallel byte shifting is connected to the data bus which connects the main storage unit to the system and comprises logic which selects predetermined byte lines. Information from the individually selected byte lines is temporarily stored in parallel buffer registers and subsequently returned to a different byte line to provide byte shifting without the requirement of shift registers or complex logic.

Abstract: A switching circuit for automatically selecting one of a plurality of normally operable asynchronous oscillators is provided with a selection switch for selecting a new oscillator while the formerly selected oscillator is still producing an output. The switching circuit employs the output of the newly selected oscillator to disable the formerly selected oscillator and to subsequently enable the output of the newly selected oscillator to be coupled to the oscillator output of the switching circuit, thus, preventing switch-over from one oscillator to the other during a metastable period.

When predetermined byte lines to the byte shifters are selected, control means are provided to activate a set of shift select means connected to error checking circuits. The error checking circuits comprise logic gating means for checking the proper selection of byte lines and for storing a signal indicative of an error or absence of an input error in the error storage means. When the data byte is being transferred out or read out of the byte shifter, the error storage means is read out to determine the presence or absence of an output error from the error storage means.
