Terminal device having communication interface configured to communicate with printer, and non- transitory computer-readable recording medium containing instructions therefor
Whether there exists a side area image within side areas of the recording medium is determined. When it is determined that there exists no image within the side areas, a command is transmitted to a printer. The command causes a printer to start conveying of the recording medium at an earlier timing. The side areas of the recording medium are difficult to be heated by a heater arranged at a central portion of a fixing roller. Therefore, in order to heat the side areas, a long time for heating by the heater is necessary. When there is no image within the side areas, the heating time is shortened. Thereby, it is possible to start conveying the recording medium at an early timing, and a time period for completing a printing operation can be shortened. |

Non-rasterized image streaming system that uses ray tracing samples
Secure rendering system that creates ray tracing samples with obfuscated positions, so that images can only be viewed by an authorized consumer able to recover the sample positions. Obfuscation of ray directions is integrated into the rendering process, for example by incorporating encryption into a lens shader. The rendering system never stores or transmits an image without obfuscating positions, so even the rendering system cannot see the image it is rendering. Embodiments may use public key cryptography, so that encryption of sample positions is done with a public key, and only the owner of the secret private key can view the rendered image. Since keys are asymmetric, the rendering system cannot decrypt the obfuscated samples. Piracy of rendered images is therefore mitigated. Some compositing operations may be performed on the secure rendering output prior to decrypting sample positions; for example, colors may be modified globally or for selected objects. |

Methods and systems for performing a model driven domain specific search
This disclosure relates to a model driven framework for realizing domain specific search system for unstructured text. The framework has two parts: information extraction system for defining various models such as a meta model, an instance model, an extraction model and mention model and a generic domain agnostic search system that works by interpreting the models specified via the information extraction system. The components of the search system are completely domain agnostic with no hard coded knowledge of the domain. The search system interprets the domain models specified in terms of the meta model to impart domain specificity to the search engine. In this sense, the framework is domain agnostic and it can be tailored for a new domain by just specifying domain related information in terms of the meta model. The model driven approach obviates need for re-coding the search system for any new domain of interest. |

An exemplary method includes storing a control file identifying a test case for testing a software application. A first expected result may be extracted from a device storing expected results of the software application, the first expected result being identified by the control file. A first actual result may be extracted from a device storing actual results output by the software application, the first actual result being identified by the control file. The first expected result may be compared with the first actual result to determine whether the first actual result matches the first expected result. A result file indicating whether the test case passed or failed is generated, and the test case has passed when the first actual result matches the first expected result. The result file may be stored in a storage device. |

Diminution of test templates in test suites
A method, apparatus and product for reducing a number of test templates in a test suite. The method comprises determining, for a first test template of the test suite, a first probabilities vector comprising a first plurality of coverage probabilities with respect to a set of coverage events. The method comprises determining, for a second test template of the test suite, a second probabilities vector comprising a second plurality of coverage probabilities with respect to the set of coverage events. The method further comprises determining that the first test template is statistically dominant over the second test template based on the first probabilities vector and based on the second probabilities vector. The method further comprises providing an output based on the determination of the statistically dominant test template. |
