Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for selecting actions for an agent in a target environment. In particular, the actions are selected using an environment model for the target environment that is parameterized using interactions of the agent with the target environment and one or more source environments.

Abstract: Sample size determination techniques in sequential hypothesis testing in a digital medium environment are described. The sample size may be determined before a test to define a number of samples (e.g., user interactions with digital marketing content) that are likely to be tested as part of the sequential hypothesis testing in order to achieve a result. The sample size may also be determined in real time to define a number of samples that likely remain for testing in order to achieve a result. The sample size may be determined in a variety of ways, such as through simulation, based on a gap between conversion rates for different options being tested, and so on.

Abstract: Embodiments of the present invention are directed at providing a sequential multiple hypothesis testing system. In one embodiment, feedback is collected for hypothesis tests of a multiple hypothesis tests. Based on the collected feedback, a sequential p-value is calculated for each of the hypothesis tests utilizing a sequential statistic procedure that is designed to compare an alternative case with a base case for a respective hypothesis test. A sequential rejection procedure can then be applied to determine whether any of the hypothesis tests have concluded based on the respective p-value. A result of the determination can then be output to apprise a user of a state of the multiple hypothesis test. This process can then be repeated until a maximum sample size is reached, termination criterion is met, or all tests are concluded. Other embodiments may be described and/or claimed.

Abstract: Paired testing techniques in a digital medium environment are described. A testing system receives data that describes user interactions, e.g., with digital content or other items. The data is organized by the testing system as pairs of user exposures to the different item. Filtering is then performed based on these pairs by the testing system to remove “tied” pairs. Tied pair are pairs of user interactions that result in the same output for binary data (e.g., converted or did not convert) or are within a defined threshold amount for continuous non-binary data. The filtered pair data is then tested, e.g., until criteria of a stopping rule are met as part of sequential hypothesis testing. The testing, for instance, may be used to evaluate which item of digital marketing content exhibits a greater effect, if any, on conversion and control subsequent deployment of this digital marketing content as a result.

Abstract: A method is provided for milling a thermal barrier coated metal part. This method includes selectively removing a portion of a ceramic coating using a mechanical cutting tool, thereby forming a counterbore, and machining the metal part through the counterbore. A drilling head for drilling thermal barrier coated metal parts is also provided. The drilling head comprises a mechanical cutting tool, which is operable to mill through ceramic, and an electrode for electrical discharge machining. The electrode may be used to mill the metal part, and may be interchangeable with the mechanical cutting tool.

Abstract: A GGSN receives a request associated with a session creation for a mobile entity. The GGSN begins a process (a four-way handshake) for obtaining network access configuration parameters for the mobile entity and responds to the request prior to the completion of the four-way handshake. The GGSN then completes the four-way handshake. A GGSN creates an association between a first IP address and a first mobile entity and thereafter requests an IP address for a second mobile entity. In response thereto, the GGSN receives the first IP address, which the GGSN declines for the second mobile entity and reserves for the first mobile entity. The GGSN requests an IP address for the second mobile entity a second time and receives a second IP address that is different from the first IP address.

Abstract: A method and apparatus for synchronized hand off from a cellular network (138) to a wireless network (100) includes an antenna (110) capable of receiving a synchronization channel and a pilot channel (112). Within the wireless network (100) is an access point (104) and a cellular timing recovery receiver (106) coupled to the antenna (110). The cellular timing recovery receiver (106) receives the synchronization channel and the pilot channel (112), which are provided to the access point (104) from a cellular base station (114). The cellular timing recovery receiver (106) thereupon generates a clock pulse (120) and a clock setting signal (122) which are provided to the access point (104), which are utilized to synchronize an internal clock with respect to the timing of the cellular base station (114). Thereupon, the wireless area network (100) may be synchronized with a cellular network (138) message information (150c).

Abstract: An apparatus and method provides synchronous communication in a communication environment (102) wherein multiple base stations are adapted to operate on the same frequencies. In particular, the base stations which operate within range of one another must be coordinated to minimize interference with other base stations which may otherwise operate independently. Each base station operating in a system will determine whether another base station operating on the same frequencies is within range (310). One of the base stations will assume a role as a master and the remaining base station will then synchronize to the master base station (312). The preferred methods for synchronizing the base stations includes signaling protocols (702, 902) and collision avoidance techniques for digital multiple access communication systems.

Abstract: A fast responding, low jitter, digital phase lock loop which is especially suited for synchronous, non return to zero, digitally encoded clock recovery applications.Both leading and trailing transitions of the digital waveform triggers a monostable multivibrator which generates well defined transition pulses. These pulses are fed to a phase comparator, where they are simultaneously compared with the output of a programmable frequency divider, whose input couples to a reference frequency oscillator. The detected phase relationship between the two compared signals causes the divider to either increase, or decrease its division factor and thereby readjust the relative phase relationship between the divided signal and the digital signal until they are in phase lock.During an absence of digital signal input, provision is made for selecting a third division factor whose value is between the first and second factors.
